Polystyrene (PS) G1551, G1461, G1161 in Iran

Image
  Polystyrene (PS) G1551, G1461, G1161 in Iran Polystyrene is a synthetic polymer made from monomer styrene . It is a rigid, transparent, and lightweight plastic that is commonly used in packaging materials, insulation, disposable cups and containers, and toys. Polystyrene can be produced in two forms: solid (commonly used for packaging) and foam (used for insulation and cushioning). What is Polystyrene (PS)? Polystyrene is an inexpensive material that is easy to manufacture and mold into different shapes. It has good insulation properties, making it an ideal material for use in building insulation and packaging materials. However, polystyrene is not biodegradable and can take hundreds of years to decompose, which has led to concerns about its impact on the environment. Application of polystyrene Polystyrene foam is often used as a cushioning material for fragile items during shipping because of its ability to absorb shock. It is also used in disposable food containers bec...

Gasoline D2 or Diesel D2 in Iran

Gasoline D2 or Diesel D2 in Iran A refinery abbreviation for Gasoil is Diesel D2 or Gasoline D2 . Unlike crude distillate, it does not require reformers or additives for use. Before petrol cars as we know them today were invented, diesel engines used D2 as fuel. This is due to the fact that a German engine called Diesel requires no spark plugs. When pressure increases, the diesel engine will ignite and combust so that the heated “plug” explodes. As a result, diesel engines are based on the same principles. As a result, the refinery will add additives to the automotive diesel that you fill to make the engine more efficient and easier to start over the winter season. The “Flash Point” of diesel changes in the winter, according to the small print. Like petrol , diesel also has additives to absorb water that condenses in the cylinder – but because the nozzles are injected directly into the cylinder, ice will destroy the nozzles before the engine. Your fuel pipes may freeze and burst ...

Urea

  Urea The world’s most widely used solid nitrogen fertilizer is urea CO(NH2)2. Animal urine also contains urea , which is commonly found in nature. This material is efficient for transferring to farms and applying to fields because of its high N content. The method of production of Urea In order to produce urea fertilizer , ammonia gas (NH3) and carbon dioxide (CO2) are combined at elevated temperatures and pressures. By using specialized granulation equipment, molten urea is formed into spheres or hardened into a solid prill by falling from a tower. Biuret can be harmful when sprayed on plant foliage when two urea molecules combine during urea production. Due to carefully controlled conditions during manufacturing, most commercial urea fertilizers contain only low levels of biuret. In some cases, though, the chemical with lower biuret content can be used for special purposes. NH3 is the main input for urea production , so the material manufacturing plants are generally located...
