Sasobit - The Additive For A Cleaner Future

For decades, hot mix asphalt (HMA) had governed road and pavement construction all over the world. Hot mix asphalt was easy to produce but required a high temperature to maintain transportation and application to road surfaces. Hot mix asphalt also takes a longer time to dry up and get the surface ready for use. But the requirement of warmer temperatures often postponed road construction projects until the summer months because the hot mix asphalt just could not set right in the rains or at cooler temperatures. Another disadvantage of hot mix asphalts in road construction was that the higher temperatures required to sustain the mix resulted in consumption of more resources to fuel and sustain the mix before application.

The introduction of warm mix asphalt (WMA), made road and pavement construction a lot more efficient and cleaner. Although both hot mix asphalt and warm mix asphalt consist of the same mixture, it includes the addition of an additive like Sasobit. Sasobit, a bitumen additive, helps in reducing the viscosity of the mixture allowing itto be used at a significantly lower temperature than hot mix asphalt. The addition of Sasobit to the liquid asphalt mix brings down the operating and laying temperature by 50 to a 100 degrees resulting in better flexibility during the laying process making it beneficial for long haul projects. Introducing an additive like Sasobit to the mix reduces the temperature needed to sustain the mixture leading to a lesser amount of fuel which in turn yields fewer emissions compared to hot mix asphalts. This leads to a better working environment with fewer green house emissions being released into the atmosphere, thus making the road pavement construction process more efficient and environment-friendly.

Today more than more than 50 million tons of Sasobit modified asphalt is being used under various climatic conditions. It has been used for demanding applications such as interstate highways, airports including Doha, Frankfurt, as well as in container ports and car race tracks. With so many uses, it is only essential to get the right amount of additive in a timely manner which is why businesses and construction companies in the Middle East and North Africa region prefer Global Trust Enterprises as their trusted supplier.

The Uses Of Morpholine

Morpholine is a colorless, hygroscopic liquid bearing the chemical formula O(CH2CH2)2NH. In appearance, it is colorless, clear and free of suspended matter. It has a characteristic amine odor that is detectable above 0.1 ppm. Morpholine has a maximum water content of 0.3%.
Morpholine is mainly used as an additive in the steam systems of large power plants and refineries. It is often added in parts per million concentrations to adjust the pH levels in water that runs in the steam systems because it behaves exactly like water and also has volatility similar to water. Due to its similar volatility, it breaks up evenly in both water and steam phases which helps prevent corrosion through out the system, keeping the pH level in check.

Globally, Morpholine is also used as an emulsifier to wax fruits. By nature, almost all fruits already have a protective coating on them, but this layer wears off after being cleaned for the packing procedure. Morpholine is added in the form of a wax like substance as morpholine oleate because it dissolves well and hence can be applied evenly as a water-based liquid. Once the layer present on the fruit gets dried, only trace levels of Morpholine will be left behind. Morpholine is used for waxing fruits to help them last longer and remain fresh even during prolonged transit. It also serves as a protective coating to prevent the fruits from getting contaminated by pests and diseases.

Global Trust Enterprises provides its clients with high quality Morpholine and other organic and inorganic solvents at the most competitive prices. Its large and extended global network enables GTE to source products quickly and make just in time deliveries.

Earth Moving Equipment, How It All Began

Earth moving equipment today is being utilized in a lot of applications all over the world, from mining to construction to agriculture, and even military applications. Ever wondered how such equipment came into use and why are they used on a large scale all over the world today?

Initially before the industrial revolution companies and businesses were local and small scale which did not require a lot of man power to build them. Moreover labor was cheap (still is in certain developing countries) which is why land owners used them for their farms and smaller building projects. With the onset of the industrial revolution there was a sudden boom of large projects which required enormous amounts of man power and even the largest amount of man power was not enough which led to the slow down of most large scale projects leading to delays and increased costs for hiring laborers. With the inventions of vehicles, transportation became much easier but the shoveling and digging needed increased amounts of workers that needed to work tirelessly. Increased amount of laborers easily translated into reduced profits for development companies. Gradually, construction machines were invented which brought down the time taken to build large projects and facilities. Such equipment seemed to deliver a much better output and a lot of contractors and tradesmen soon realized their value of getting more work done in a minimal amount of time and with reduced costs.

Today earth moving equipment offers a wide variety of choices to contractors who completely rely on the smooth functioning of such equipment for their building and construction plans. The bulldozer is one of the most widely used types of earth moving equipment today for moving material, with it being available from small ones which are used for backyard shoveling for local earth moving purposes to  the massive and extremely powerful ones that are used on mining projects. The technology that goes into new age bull dozers is also very complex requiring them to have trained servicemen and operators. The most commonly used type of earth moving equipment is the excavator which is used for digging and delivering material onto dumper trucks. They consist of a boom and a bucket and are available in a large variety of sizes from the mini-excavator which weighs about 3,549 pounds, to the largest excavator used in mining which is in excess of 2,160,510 pounds. Such excavators have a heavy capacity which makes them more productive and help increase profits.

But in the end it all boils down to having the right suppliers to getting the best equipment to get your work done. This requires expertise and commitment that only Global Trust Enterprises a general trading company in Dubai can deliver. Global Trust Enterprises delivers various types of equipment and spares to its customers in the Middle East and North Region, including heavy earth moving equipment from world renowned brands such as Caterpillar, Hitachi, Kubota and Hyundai.

An Insight Into The Production And Refinement Of Aluminum

Also known as one of the most widely recycled metals on earth, aluminum is naturally occurring, although in mineral form in bauxite ores. These ores need to be processed and unlike most other metals, it is rather difficult to extract aluminum from bauxite ores because of the amount of energy required for the same. Today bauxite ores are converted to aluminum through the Hall-Heroult process of electrolysis, which results in a 99% pure aluminum metal. Better purification of aluminum can be obtained via the Hoope process which gives a more pure form of aluminum at 99.99%.

The process of electrolysis requires an enormous amount of electricity which is why most aluminum smelters are usually located near power stations. Hence it is not surprising to know that aluminum production takes place in countries where electricity is cheaper. Although there are sufficient reserves of aluminum available here on earth for future generations, it is still easier for companies to recycle existing aluminum and save on electricity costs thereby reducing the cost of the raw material itself. Recycling aluminum barely consumes 5 percent of the energy needed to produce similar virgin aluminum through the process of mining. Recycling aluminum from scrap and old parts not only makes it cheaper to obtain raw aluminum but also reduces the damage done to the environment.  

With both mining and recycling production processes set in place the applications for aluminum usage have vastly increased due to its now reduced price. Reduced prices along with aluminum’s already excellent ductility and malleability have found new applications in multiple industries. These multiple applications found their way in the form of aluminum being mixed with other metals such as copper, manganese and zinc to form alloys of aluminum. Aluminum is today used in everything from electronic devices to cars to airplanes and even rockets.

Hydraulic Vs Non-hydraulic Cement

Cement is technically a binder a chemical substance made to either hold itself to take up a form or to hold two other objects together. With an existence that traces back to the Romans, it initially consisted of a mixture of crushed rock and lime which was used as the binding substance in construction. Today, the most commonly used form of cement worldwide is Portland cement which is purpose built for the field of construction. Cement can be broadly classified into non-hydraulic cement and hydraulic cement.

Non-hydraulic cement is a basic and cheaper alternative compared to hydraulic cement. Non-hydraulic cement was the initial mixture of the original cement that was discovered centuries ago. As opposed to hydraulic cement, it does not harden when exposed to water after the cement has been set after use. What makes it a bad contender against hydraulic cement is that it takes a substantially longer time to dry off and gain strength after being set. Even in use for bricklaying in mortar, non-hydraulic cement takes a very long time to gain strength.

Due to many problems and issues faced with long drying periods along with a requirement for dry weather conditions, non-hydraulic cement proved to be a failure which lead to the development of hydraulic cement.

Hydraulic cement unlike non-hydraulic cement did not require a substantial amount of time to dry. Unlike hydraulic cement, it did not demand for the right weather conditions and dried in almost any weather. Today with various improvements in science and with new chemicals being developed, hydraulic cements have reached new heights and many more applications. Stucco mixed with hydraulic cement is now being used for finishing brick buildings in wet weather conditions. Their ability to harden lies in the process called hydration in which chemical reactions take place in the mixture without any specific requirement for the water content which is why such cements can even be set underwater.

Steel - Its Inception And Where It Is Today

Steel  is an alloy that is made of a mixture of mainly iron and 0.2% to 2.1% carbon. The production of iron plays a major role in the process of making steel. Carbon in turn is the alloying material used for alloying iron. Chromium, manganese, tungsten and vanadium are the few other materials used to alloy iron. The varying use of a mixture of these materials results in different types of steel with varied properties such as hardness and ductility which are required for different applications in multiple industries. An alloy that possesses carbon content in iron which is more than 2.1% is called cast iron and not steel. Cast iron has other purposes in the industry because of its lower melting point and enhanced castability.

Steel although first produced somewhere around 1400 BC was not easily available because the procedure which was used to produce steel was rather difficult to follow and control which made it uneconomical. But later in the mid eighteen hundreds with the invention of the Bessemer process, by Henry Bessemer, it finally became economically viable and hence the production and demand of steel increased greatly. The Linz-Donawitz process of basic oxygen steel making again made steel much easier to produce and was more economical resulting in an even wider demand for steel. The increased craving for steel at that time lied in steel’s properties of resisting rust which was much better than other metals. Steel also had better weldibility along with being easier to produce than other metals which had such properties.

Hence steel became a popular with industries that were in those days using wrought metal as the metal of choice for building tools, machinery and other equipment. Steel manufacturing today is much different and has changed leaps and bounds compared to the techniques used in the 1800s.The modern steel electric arc furnaces (EAF) have made steel production dependent more on the availability of cheap electricity, than the mining of iron ore because the furnaces being highly productive use large amounts of electricity. Today there have been vast improvements in the field of mining as well as in the production equipment. Steel industries in the Middle East and all over the world have increased the production of steel to 1,413.5 mmt in 2010, which is widely used from the enormous building and constructions projects, to the ship building industry to the automotive industry and even in day to day electronics and appliances.

Nylon Its Creation And Applications

Created during World War II to replace the silk which was used in World War II parachutes, this synthetic polymer unlike others was designed for the purpose and then used in multiple applications. During World War II the production of silk including trade routes to silk producing countries had diminished leading to silk becoming extremely expensive for the properties that it offered which is why nylon was produced by Wallace Carothers at the DuPont Experimental Station.

Worldwide demand for nylon grew immediately after it was created and even more after the War ended. The new found applications of nylon were endless and moreover it could be extensively modified for multiple applications in different industries, which is why today there are many forms of nylon available.

The most widely applied form of nylon refers to nylon 6,6 which consists of hexamethylenediamine and adipic acid. These chemicals give nylon 6,6 excellent abrasion resistance, a higher melting point and a rather compressed molecular structure.

Having such a great combination of chemicals gives nylon 6,6 a variety of characteristics such as being able to create it in a more lustrous or even dull form as per the requirement or its resistance to insects, fungi, mould, and even its ability to be resilient under severe stress. Such outstanding characteristics and being able to produce it economically make nylon a great polymer to be used in a wide variety of textiles and plastics. It has been used in making apparel, airbags, tires, ropes, hoses and much more. Solid nylon is used for a wide variety of mechanical and electronic components mainly for those that are not stressed heavily.

With vast industrial, commercial and everyday uses the demand for nylon in manufacturing is enormous.

Isododecane - It's Creation And Uses

Isododecane is a specialty oligomer which contains a mixture of highly branched C12 isoparaffins and mainly the 2, 2, 4, 6, 6-pentamethylheptane isomer. It is a chemical best suited for applications which calls for stringent demands in terms of purity and chemical stability. Isododecane is used for such applications because it is synthetic due to which it is in effect, free of aromatics, sulphur containing molecules and polar compounds.

Produced by a patented process from a pre-purified isobutene (branched C4) containing feedstock, Isododecane is used extensively for the most reactive (short half life) peroxide catalysts such as diacylperoxides and peroxy diesters. Isododecane is mainly used as either a solvent or as a dispersing agent for high reactivity organic peroxide catalysts in the polymerization process.

Isododecane is utilized in multiple forms in different applications, the most important of which is the production of polymer films. LDPE or Low Density Polyethylene is extensively produced around the world and is used for major food packaging applications. Isododecane is free of all aromatic and naphthenic molecules, which ensures that the finished LDPE film remains odor free. With the ability to with stand temperatures of about 80 degrees continuously, this film can be created in translucent and opaque varieties which can be flexible and tough but eventually breakable. LDPE is used for manufacturing various types of plastic containers, plastic bottles, packaging bags for computer components and a variety of molded laboratory paraphernalia.

Lubricants And Their Key Functions

A lubricant is a substance often in a liquid form, introduced between two moving surfaces to reduce the friction between them, improving efficiency and reducing wear. A lubricant is oil based and almost all types of machinery require the use of lubricants in order to function properly. Lubricants reduce direct metal to metal contact and protect the machinery parts against wear and corrosion for a long lasting performance. Lubricants are used widely in sectors like construction, agriculture, transport, petrochemical industries, oil & gas industries, etc.

Let’s check out some of key functions performed by lubricants:

•    Keeps moving parts apart: Lubricants are typically used to separate moving parts in a system or a machine by forming a thin layer between the moving parts. This helps to reduce friction, and heat generation while delivering less noise and vibrations.

•    Reduces friction: Another key point of using a lubricant is that it reduces friction within the system or machinery. It contains certain additives known as friction modifiers that chemically bind to metal surfaces to reduce surface friction and improve efficiency.

•    Removes contaminants and debris: This is one of the most important advantages of using a lubricant. Machines that regularly generate debris and contaminants such as automotive engines use a lubricant which easily removes and filters those particles out of the system.

•     Protection against wear and corrosion: Lubricants contain anti-wear or extreme pressure additives that boost their performance against wear, fatigue and corrosion.

There are about 3 types of lubricants in general, biolubricants, the ones that are made from vegetable oils and other animal and plant sources, synthetic oils which are developed and well engineered for the demanding applications they are used in and finally dry lubricants such as Teflon or graphite which are used to reduce friction without the use of a liquid.

Polymers, Its Types And Its Uses

A polymer is a large molecule which is held together by a number of repeating structural units obtained through the process of polymerization. In recent years, polymers have gained an increased presence in the chemical industry with their highly defined properties and uses. Polymers are widely used in petrochemical industries, oil & gas companies, steel & aluminum industries, plastic industries, and so on.

Types of Polymers & Its Uses:

1) Polycarbonate: It is a clear plastic used to make shatterproof windows, lightweight eyeglass lenses, and many other items that have lightweight applications. There are two types of polycarbonates, thermoplastic and thermoset. A thermoplastic can be molded in any shape when it is hot whereas a thermoset does not melt, and it cannot be remolded nor recycled. They are used to make things that need to be really strong and heat resistant.

2) Polyethylene: This is probably the polymer that you see and use the most in your day to day routine. Polyethylene is the most popular and widely used plastic in the world. It is used to make items like grocery bags, shampoo bottles, children's toys, plastic food containers and even bullet proof vests.

3) Polyesters: Polyesters are the polymers, in the form of fibers which are now also made into a fabric. It is used to make normal clothing since polyester is economical. Apart from clothes it is also a plastic, and is often used to make shatterproof bottles that hold your favorite refreshing beverages and drinks.

4) Polystyrene: Polystyrene is an inexpensive and hard plastic commonly used in everyday life. The outside housing of the computer you are using is probably made of polystyrene, as well as the housings of electrical equipment like hairdryers, TVs and kitchen appliances. Model cars and airplanes are made from polystyrene, as well as many other toys. There is also foam packaging and insulation and a lot of molded parts on the inside of your car, like the radio knobs.
