Lysine is an alkaline essential amino acid that cannot be synthesized autonomously in animals and must be supplemented through feed. The ε-amino group in its molecular structure has high reactivity and can effectively promote protein anabolism and increase the growth rate of muscle tissue. Adding lysine to feed can make up for the imbalance of amino acids in grain raw materials.
MEA As Corrosion Inhibitor In Metal Surface Coatings
MEA can be used directly as a corrosion inhibitor, but in actual industrial applications, it is often compounded with other solvents or additives to optimize performance. The specific formula needs to be designed according to the metal type, environmental conditions and coating syste.
Common retarders in mineral processing chemical products
The more commonly used retarders in mineral processing reagents are: sodium sulfide, zinc sulfate, sodium nitrate, potassium dichromate, water glass, lime, yellow blood salt, tannin, starch (dextrin), carboxymethyl cellulose, etc.
Based on the dispersion form of inorganic compounding agents in rubber, the mechanism of action of nano zinc oxide in rubber and its effect on the properties of rubber are studied. During the vulcanization process, zinc oxide as an active agent reacts with organic accelerators, stearic acid, sulfur, etc. on the surface of zinc oxide particles. Replacing ordinary indirect zinc oxide with an equal a
Traditional off-season prices doubled. Why did the shipping costs rise "off-se
Since mid-April this year, shipping costs have continued to rise, and prices have changed almost every week. Now, according to inquiries, the price of a standard container from Shanghai to Hong Kong is between US$5,500 and US$6,000 in late June, which has doubled compared to a month and a half ago.

Plastic Additives are key materials used to improve plastic performance, processing technology or give special functions, and there are many types. The following are the main classifications and representative additives, summarized in combination with current industry applications:
Ethanol is a volatile, colorless, and transparent liquid at room temperature and pressure, with a characteristic wine-like odor and mild irritancy. It exhibits low toxicity and is highly miscible with water in all proportions, as well as with most organic solvents. When mixed with air, ethanol vapor can form explosive mixtures. As a fundamental organic chemical feedstock, it serves as a versatile
