Taw qhia
Cov xim tsis muaj xim, tsis muaj ntxhiab, pob tshab, hygroscopic viscous kua. Nws muaj ib tug ntsim qab zib. Nws solubility zoo ib yam li ethylene glycol, tab sis nws solubility rau hydrocarbons muaj zog dua. Diethylene glycol tuaj yeem ua rau miscible nrog dej, ethanol, ethylene glycol, acetone, chloroform, furfural, thiab lwm yam. Nws yog immiscible nrog ether, carbon tetrachloride, carbon disulfide, ncaj saw aliphatic hydrocarbon, aromatic hydrocarbon, thiab lwm yam Rosin, shellac, cellulose acet thiab cov roj feem ntau yog insoluble hauv diethylene glycol, tab sis muaj peev xwm yaj cellulose nitrate, alkyd resins, polyester resins, polyurethane, thiab feem ntau dyes. Flammable, tsawg toxicity. Muaj cov tshuaj lom neeg ntawm cawv thiab ether.
Txoj kev khaws cia
1. Khaws rau hauv qhov chaw txias thiab qhuav. Xyuas kom muaj qhov cua zoo hauv lub rooj cob qhia.
2. Khaws kom deb ntawm qhov hluav taws kub thiab dej. Khaws kom deb ntawm oxidants
Siv
1. Feem ntau yog siv los ua cov roj dehydrating tus neeg sawv cev thiab cov tshuaj tsw qab extraction hnyav. Nws kuj yog siv los ua hnyav rau cellulose nitrate, resin, roj, luam ntawv number case, textile softener, xov tus neeg sawv cev, thiab extraction ntawm coumarone thiab indene los ntawm thee tar. Tsis tas li ntawd, diethylene glycol kuj tseem siv los ua cov roj nres, celluloid softener, antifreeze thiab diluent hauv emulsion polymerization. Kuj tseem siv rau roj hmab thiab resin plasticizer; Polyester cob; Fiberglass; Carbamate ua npuas ncauj; Kev tsim cov roj lubricating viscosity improver thiab lwm yam khoom. Siv rau hluavtaws unsaturated polyester cob, thiab lwm yam.
2. Siv los ua hluavtaws polyester cob, plasticizer, thiab lwm yam. Kuj tseem siv los ua cov tshuaj tua kab mob, cov roj dehydrating tus neeg saib xyuas, plasticizer, hnyav, cov tshuaj tsw qab extraction tus neeg saib xyuas, cov luam yeeb hygroscopic tus neeg saib xyuas, cov khoom siv roj nplua nyeem thiab cov khoom tiav, muab tshuaj txhuam thiab txhua yam ntawm cov nplaum los tiv thaiv kom qhuav. , VAT dye hygroscopic hnyav, thiab lwm yam Nws yog ib qho hnyav hnyav rau roj, resin thiab nitrocellulose.
