High-speed copper plating of welding wire is brown brown liquid, which is used for non electrodeposition of high-speed copper plating film on iron to facilitate wire drawing process. It can make copper ions deposit orderly, make copper deposit compact, and have strong adhesion. At the same time, the complexing agent can also effectively complexe excessive iron ions in the tank solution, so that the tank solution remains stable. The deposition film is golden yellow and pink, which is loved by users. It can be used as immersion or continuous production line. The weight of copper film is 5-20g/m2

Ammonium nitrate content is more than 99%, the appearance is white granular crystals, no impurities visible to the naked eye.
2. Purpose:
Explosive material: granular ammonium oil explosive is made by mixing porous ammonium nitrate with raw oil. Its speed can reach more than 3 200 m/s. This explosive has strong explosive power, safe and reliable use, low price, cost saving, and can usually reduce the cost by 20%-40%. At present, this kind of explosive has been widely used in mining, construction, railway and highway construction, agricultural and water conservancy construction and national defense and other fields.
Methyl tert-butyl ether (MTBE) is a colorless, transparent, low-viscosity, volatile liquid with a distinctive odor and an oxygen content of 18.2%.
lts vapor is heavier than air. Diffuses along the ground and burns when co-existing with strong oxidants.
The main use of methyl tert-butyl ether is as an organic solvent and can also be used as a gasoline additive to make it more antiknock.
Application
ethyl tert-butyl ether (MTBE) is mainly used as gasoline additive, has excellent knock resistance, improves octane number, and can also be cracked to produce isobutene has good miscibility with gasoline, less water absorption, no pollution to the environment, can be improved as an analytical solvent, extractant, in chromatography especially high pressure liquid chromatography as a removal agent, and some polar solvents such as water, methanol, ethanol and other azeotrope formation. Mtbe also has a mild narcotic effect.

Acetonitrile is an organic compound with the molecular formula CH3CN or c2h3n. It is a colorless liquid, highly volatile, with a special smell similar to ether, excellent solvent performance, and can dissolve a variety of organic, inorganic and gaseous substances. It has certain toxicity and is infinitely miscible with water and alcohol. Acetonitrile is an important organic intermediate, which can undergo typical nitrile reactions and is used to prepare many typical nitrogen-containing compounds. Acetonitrile can be used as a solvent for the synthesis of vitamin A, cortisone, carboamine drugs and their intermediates, and also as an active medium solvent for the manufacture of vitamin B1 and amino acids. It can replace chlorinated solvent. It is used in vinyl coating, fatty acid extractant, alcohol denaturant, butadiene extractant and solvent of acrylonitrile synthetic fiber. It is also used in fabric dyeing, lighting, perfume manufacturing and photosensitive material manufacturing.
Chemical analysis and instrumental analysis
Acetonitrile is an organic modifier and solvent used in thin layer chromatography, paper chromatography, spectroscopy and polarographic analysis in recent years. Since high-purity acetonitrile does not absorb ultraviolet light at 200nm ~ 400nm, an application being developed is as a solvent for high-performance liquid chromatography HPLC, which can make the analytical sensitivity as high as 10-9 levels.
Intermediate of synthetic medicine and pesticide
Acetonitrile can be used as an intermediate in the synthesis of various medicines and pesticides. In medicine, it is used to synthesize a series of important pharmaceutical intermediates, such as vitamin B1, metronidazole, ethambutol, aminopteridine, adenine and antitussive; In pesticides, it is used to synthesize pyrethroid insecticides, acetaminophen and other pesticide intermediates.
Semiconductor cleaning agent
Acetonitrile is an organic solvent with strong polarity. It has good solubility in grease, inorganic salt, organic matter and polymer compounds. It can clean grease, wax, fingerprints, corrosive agent and flux residues on silicon wafers. Therefore, high purity acetonitrile can be used as semiconductor cleaner.

Appearance: Light yellow colloid,Yellow cream
Grade: Cosmetic and pharma grade
Standard: USP, EP
Features:Lanolin is a natural waxy substance derived from crude wool wax (also often referred to as wool grease or wool fat). It's obtained from the liquids resulting from scouring sheep wool. The wax is separated from the liquid using high speed centrifugation. It's then processed and refined in various stages, including:
#Reducing free fatty acids, soap and water content
#Eliminating contaminants
#Deodorising and bleaching.
