Kev Taw Qhia
Ib yam kua nplaum uas tsis muaj xim, tsis muaj ntxhiab, pob tshab, thiab hygroscopic. Nws muaj qhov qab zib ntsim. Nws cov solubility zoo ib yam li ethylene glycol, tab sis nws cov solubility rau hydrocarbons muaj zog dua. Diethylene glycol tuaj yeem sib xyaw nrog dej, ethanol, ethylene glycol, acetone, chloroform, furfural, thiab lwm yam. Nws tsis sib xyaw nrog ether, carbon tetrachloride, carbon disulfide, straight chain aliphatic hydrocarbon, aromatic hydrocarbon, thiab lwm yam. Rosin, shellac, cellulose acetate, thiab feem ntau cov roj tsis yaj hauv diethylene glycol, tab sis tuaj yeem yaj cellulose nitrate, alkyd resins, polyester resins, polyurethane, thiab feem ntau cov xim. Flammable, tsis muaj tshuaj lom. Muaj cov khoom siv tshuaj lom neeg zoo li cawv thiab ether.
Txoj Kev Khaws Cia
1. Khaws cia rau qhov chaw txias thiab qhuav. Xyuas kom muaj cua nkag tau zoo hauv lub hoobkas.
2. Khaws cia kom deb ntawm hluav taws thiab dej. Khaws cia kom deb ntawm cov tshuaj oxidants
Siv
1. Feem ntau siv ua cov roj dehydrating agent thiab aromatics extraction solvent. Nws kuj siv ua cov solvent rau cellulose nitrate, resin, grease, printing ink, textile softener, finishing agent, thiab extraction ntawm coumarone thiab indene los ntawm thee tar. Tsis tas li ntawd, diethylene glycol kuj siv ua cov roj nres, celluloid softener, antifreeze thiab diluent hauv emulsion polymerization. Kuj siv rau roj hmab thiab resin plasticizer; Polyester resin; Fiberglass; Carbamate ua npuas ncauj; Kev tsim cov roj lubricating viscosity improver thiab lwm yam khoom. Siv rau synthetic unsaturated polyester resin, thiab lwm yam.
2. Siv ua cov tshuaj polyester tsis muaj roj, plasticizer, thiab lwm yam. Kuj siv rau antifreeze, roj dehydrating agent, plasticizer, solvent, aromatics extraction agent, cigarette hygroscopic agent, textile lubricant thiab finishing agent, paste thiab txhua yam adhesive anti-drying agent, VAT dye hygroscopic solvent, thiab lwm yam. Nws yog ib qho tshuaj solvent rau roj, resin thiab nitrocellulose.
