Lub hauv paus rau phau ntawv
Ib qho tsis muaj kob, tsw ntxhiab, pob tshab, hygroscopic viscous kua. Nws muaj qhov qab zib ntsim. Nws qhov solubility zoo ib yam li ethylene glycol, tab sis nws solubility rau hydrocarbons muaj zog dua. Diethylene glycol tuaj yeem ua kom tsis meej nrog dej, ethylene glycoleide, carbon disciscibride, fidfacic, floculose acetate, thiab cov roj feem ntau yog insoluble hauv Diethylene glycol, tab sis tuaj yeem tshem cellulose nitrate, alkyd resins, polyester resins, polyester resins, polyourethane, thiab cov neeg ua ke. Flammable, tsawg toxicity. Muaj cov tshuaj tiv thaiv cov tshuaj tiv thaiv dej cawv thiab ether.
Cia Txoj Kev
1. Khaws cia rau hauv qhov chaw txias thiab qhuav. Ua kom zoo rau qhov cua hauv lub rhiav.
2. Txav deb ntawm hluav taws thiab dej los. Khw kom deb ntawm oxidants
Kev siv
1. Siv tau raws li cov roj txiav plaub hau thiab cov ntxhiab extraction cov kuab tshuaj. Nws tseem raug siv los ua cov kuab tshuaj rau cellulose nitrate, roj, tshuab luam ntawv, thiab rho tawm ntawm Coumarone thiab kev tawm tsam los ntawm cov tar thee. Ib qho ntxiv, diethylene glycol kuj tau siv los ua lub roj nres, celluloid mosenener, tshuaj tua kab mob polulsion. Kuj siv rau roj hmab thiab cov tshuab yas ua kom yooj yim; Polyester Resin; Fiberglass; CARBAMATE UA HAUJ LWM; Kev tsim cov roj lubricating viscosity brocority improve thiab lwm yam khoom. Siv rau cov khoom siv hluavtaws tsis ruaj khov polyester resin, thiab lwm yam.
2. Siv cov khoom siv hluavtaws tsis ruaj khov, yas, siv cov roj pleev thiab txhua yam ntawm cov tshuaj tua kab mob Resin thiab nitrocellulose.
