Isododecane is an important ingredient in cosmetics. It can be used as an emulsifier for pastes in cosmetic products to help mix water and oil-based ingredients together to achieve a uniform distribution and texture of the product. Since it is colorless, tasteless and odorless, it does not affect the aroma or color of the cosmetic. It is used as a cosmetic solvent to make the product fresh, easy to wipe, and can reduce and prevent the outflow of water from the skin. In addition, due to its stability, isododecane is often used as a solvent for chemical reactions. In analytical chemistry, it is also commonly used as an internal standard to determine the yield and conversion rate of a reaction, and a known concentration of Isododecane can be added to the analytical sample to correct the analytical data and ensure accuracy.

The compressed air first enters the pre-cooler for initial cooling, and then passes through the pre-cooling/reheating section of the high-performance 3-in-1 plate heat exchanger for further cooling. It subsequently enters the evaporator section, where it is rapidly cooled and the condensed moisture is separated. The treated low-temperature compressed air then returns to the pre-cooling/reheating heat exchanger, where it exchanges heat with the incoming hot compressed air. This reheats the dry compressed air before it is discharged from the dryer. The refrigeration system precisely adjusts the compressor speed according to changes in system load. The operating frequency is automatically regulated to match the actual air treatment demand, ensuring stable and energy-efficient operation.

Agricultural urea N46 46%


Properties of urea
Urea, also known as carbamide, carbamide and urea. Pure urea is white, tasteless, odorless, needle shaped or prismatic crystal, with a melting point of 132.7 under normal pressure. It is hygroscopic, deliquescent, hydrolyzable, and weakly alkaline. It is made into compound fertilizer with acid fertilizer. Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. Urea is one of the simplest organic compounds. The most important use of urea is as fertilizer. Its nitrogen content is more than 46%. After being converted into ammonium carbonate in soil, urea is hydrolyzed and absorbed by plants. It is the nitrogen fertilizer with the highest nitrogen content at present.
Molecular formula of urea: CO (NH2) 2, molecular weight 60.06, density 1.335g/cm The melting point is 132.7. Soluble in water and alcohol, insoluble in ether and chloroform. It is slightly alkaline. It can react with acid to form salt. It has hydrolysis. Condensation reaction can be carried out at high temperature to produce biuret, triuret and cyanuric acid. Heat to 160 and decompose to generate ammonia gas and turn into cyanic acid at the same time. Urea can be hydrolyzed into ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). Unstable to heat, heat to 150 160 to deamination to biuret. Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20 , and the aqueous solution shows neutral reaction. There are two kinds of urea products: crystalline urea is white acicular or prismatic crystal with strong hygroscopicity; Granular urea is a translucent particle with a particle size of 1~2mm, which has a smooth appearance and improved moisture absorption.
Urea is a physiologically neutral fertilizer, which does not leave any harmful substances in the soil and has no adverse effects after long-term application. However, a small amount of biuret, also known as biuret, will be produced when the temperature is too high during granulation, which has an inhibitory effect on crops. Urea is molecular before conversion and cannot be adsorbed by soil, so it should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. Urea is the first synthetic organic substance and widely exists in nature, such as 0.4% urea in fresh human feces.

The new version of national standard GB/T2440-2017 for urea has been officially implemented since July 1, 2018. Compared with the replaced 2001 standard, certain adjustments have been made.
New standard GB/T2440-2017

Dx51d galvanized sheet material is a non-ferrous alloy mainly composed of zinc as the matrix and other elements. The main alloy elements are aluminum, copper, magnesium, etc. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and is resistant to atmospheric corrosion. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy. The commonly used cast zinc alloy is zinc aluminum copper magnesium alloy. Its casting process performance is good, and the cooling rate has little impact on the mechanical properties. It is mainly used to manufacture mechanical parts, toys, decorations, household appliances, etc. The commonly used wrought zinc alloys are zinc aluminum alloy and zinc copper alloy. The former contains 4%~15% aluminum. In order to improve the strength and hardness of the alloy, a small amount of copper, magnesium and other alloy elements are added. It has high strength and is easy to form. It can replace some brass or duralumin to make precision forgings. The latter is 0.7%~1.5% copper, which can increase the strength and impact toughness of the alloy and reduce the plasticity. Zinc copper alloy is suitable for making daily hardware products or replacing part of brass.

Galvanized sheet G550 belongs to high-strength series galvanized sheet, with high requirements for tensile strength and yield strength. Its minimum yield strength is 560Mpa, minimum tensile strength is 650Mpa, and zinc layer thickness is 275g/m2. It has strong corrosion resistance and is mainly used for building structures with high strength requirements, such as Z-shaped steel, C-shaped steel, floor bearing plate, etc.

Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel.
The following are some specifications that we often export, for reference only, if you have special requirements, we can customize, we will have professional designers to provide you with the most satisfactory style.

Vanadium catalyst could be applied in many fields, such as sulfur-based acid production, pyrite-based acid production, nonferrous smelting gas-based acid production, gypsum-based acid production etc.

Type S108 Series sulfuric acid catalysts were invented in early 80s�¢?? by China. The advantages of them are outstanding. In general, they are low ignition temperature, high activity in low temperature, high-resistant crushed strength etc. If can be used together with medium temperature type catalyst, such as, S101, you can make more profits; for instance, high conversion, and lowering environmental pollution.

Type S108 series are low temperature catalysts which suit for 1/3 top of the first bed to decrease inlet operating temperature, and 4th bed, 5th bed to improve equilibrium conversion and decrease gas emission.
