Cov tshuaj nquag ntawm epoxy compounds

Tso lus

1. Ethylene oxide
Kuj tseem hu ua ethylene oxide, 1, 2-ethylene oxide, dihydroethylene oxide. Flash point -28.9 degree . Sib tov nrog huab cua los tsim cov khoom tawg. Kev sib cuag nrog amines, ammonia, potassium, covalent hydrides los tsim cov tshuaj tiv thaiv polymerization tawg, cov tshuaj tiv thaiv yog txaus ntshai. Tiv tauj nrog cov khoom siv catalytic (anhydrous hlau, tin, aluminium chloride, hlau ntshiab, aluminium oxide, sodium hydroxide) los tsim cov tshuaj phem. Rearrangement los yog polymerization exothermic cov tshuaj tiv thaiv. Cov kua qaub me me, alkali hlau, thiab oxidants tuaj yeem ua rau muaj kev cuam tshuam. Tsis txhob sib cuag nrog tooj liab, magnesium, mercury, nyiaj thiab lawv cov alloys (xws li solder) los tiv thaiv kev tsim cov hlau tawg acetylated.
Tiv thaiv lub thawv puas, cua sov, thiab lub teeb. Nws tuaj yeem hnov mob hauv ib qho insulator los ua polyethylene glycol, uas ua rau cov cua sov tsis tu ncua thiab ignites ntawm<100℃. It reacts violently with strong oxidants, alcohols, aluminum, amines, glycerol, nitrogen pentoxide, and m-nitroaniline; it is incompatible with ethyl bromide, magnesium perchlorate, mercaptans, salts, alkanethiols, and flammables. Low conductivity, static electricity will be generated when flowing or agitating. Attacks some rubber, plastic and cotton fabrics.
2. Propylene oxide
Kuj tseem hu ua propylene oxide, methyl ethylene oxide, 1, 2-propylene oxide, 2, 3-propylene oxide. Flash point -37 0 degree . Sib tov nrog huab cua lossis oxygen los tsim cov khoom tawg. Kev phom sij polymerization tshwm sim nrog acids, caustic alkalis, thiab perhalides; reacts nrog dej thiab dej vapor los tsim peroxides tsis ruaj khov. Reacts nrog acids, ammonia, amines, acetylated hlau, thiab av nplaum-raws li absorbents; incompatible nrog anhydrous hlau chlorides, ammonium hydroxide, thiab ntsev. Tsawg conductivity, hluav taws xob zoo li qub yuav raug tsim thaum ntws los yog agitating, thiab nws cov vapor yuav ignite. Tawm tsam qee cov roj hmab, yas thiab paj rwb ntaub.
