iHeir-FT bamboo and wood anti-mildew powder is a new type of anti-mildew powder that further enhances the effectiveness of anti-mildew and has a fresh aroma based on the original product formula. iHeir-FT bamboo and wood anti-mildew powder, as a new type of anti-mildew agent, does not contain toxic substances such as lithosulfide, heavy metals, sulfur, dimethyl fumarate (DMF), etc.
and meets the environmental requirements of the European Union, and the product does not produce waste after use and can be recycled, and is a new generation of comprehensive anti-mildew fungicide. Anti-mold fungicide.
1-(β-Hydroxyethyl)-2-alkyl-2-imidazoline compounds are prepared from higher fatty acids and N-(aminoethyl)ethanolamine through reduced compression and dehydration reactions.
N-CH: RC OH+HgN-CH, CHy NH-CH, C Hz OH- reduced pressure dehydration,
They can not only be used directly as antistatic agents, but also important intermediates for the synthesis of quaternary ammonium salts and amphoteric imidazoline antistatic agents.
Amine salt antistatic agent
Broadly speaking, quaternary ammonium salts, alkyl imidazoline salts, alkyl amine salts, cycloalkyl amine salts and cyclic amine salts belong to the category of amine salt antistatic agents. Salts and alkylimidazoline salts have a relatively important position in the field of antistatic agents, and are generally listed as an independent system. Therefore, amine salt antistatic agents usually refer to the direct reaction of alkylamines and cycloalkylamines with acids. Neutralized products, including alkylamine hydrochloride and phosphate, alkylamine ethylene oxide adduct salt compounds, higher fatty acid and ethanolamine (including monoethanolamine, ft wax applications diethanolamine, triethanolamine) ester salts, The salt of stearamidoamine and the phosphate of cyclohexylamine, etc. Such antistatic agents are particularly sensitive to heat.
The main cationic antistatic agent.
Non-ionic antistatic agent
Non-ionic antistatic agents are not as effective as ionic antistatic agents. That is, to achieve the same antistatic effect, the amount of non-ionic antistatic agents is usually twice or more than that of ionic antistatic agents. However, non-ionic antistatic agents have good thermal stability and low toxicity, so they have become the category with the largest output among polymer antistatic agents. As far as the current situation is concerned, non-ionic antistatic agents mainly include polyols and polyols. Ethylene oxide adducts of esters, fatty alcohols or alkylphenols, ethylene oxide adducts of fatty amines or fatty amides, etc. Among them, fatty amine ethylene oxide adducts, fatty amide ethylene oxide adducts, and fatty acid polyol esters are the most consumed, accounting for about 65% of the entire polymer antistatic agent.
