Kev Siv
Cov khoom no yog siv ua cov kuab tshuaj rau ntau yam roj thiab cov rog, lignin, nitrocellulose, cellulose acetate, cov xim yaj hauv cawv, thiab cov resins hluavtaws; ib qho reagent rau kev txiav txim siab hlau, sulfates, thiab carbon disulfide; ib qho diluent rau coatings; thiab hauv kev ntim khoom thiab kev kaw ntawm cellophane, cov varnishes qhuav sai, thiab enamels. Nws kuj tseem siv tau ua tus neeg nkag mus thiab tus neeg sawv cev leveling hauv kev lag luam zas xim, lossis ua plasticizer thiab brightener. Raws li ib qho nruab nrab hauv kev tsim cov organic compounds, ethylene glycol monomethyl ether feem ntau yog siv hauv kev tsim cov acetate thiab ethylene glycol dimethyl ether. Nws kuj yog ib qho khoom siv raw rau kev tsim cov bis (2-methoxyethyl) phthalate plasticizer. Cov sib tov ntawm ethylene glycol monomethyl ether thiab glycerol (ether:glycerol = 98: 2) yog ib qho additive rau roj dav hlau tub rog, uas tuaj yeem tiv thaiv kev khov thiab tiv taus cov kab mob corrosion. Thaum ethylene glycol monomethyl ether siv los ua tus neeg sawv cev tiv thaiv sludging rau roj dav hlau, qhov ntxiv dav dav yog 0.15% ± 0.05%. Nws muaj hydrophilicity zoo. Hauv roj, nws cov hydroxyl pawg tsim cov hydrogen bond koom tes nrog cov molecules ntawm cov dej me me hauv cov roj. Tsis tas li ntawd, nws tus kheej qhov chaw khov yog qis heev, yog li txo qhov chaw khov ntawm dej hauv cov roj thiab tiv thaiv cov dej los ntawm precipitating li te. Ethylene glycol monomethyl ether kuj yog ib qho tshuaj tiv thaiv kab mob.
Nws ua haujlwm ua cov tshuaj reagent rau kev txiav txim siab ntawm hlau, sulfate thiab carbon disulfide, thiab ua haujlwm ua cov kuab tshuaj rau ntau yam roj thiab cov rog, lignin, nitrocellulose, cellulose acetate, cawv-soluble dyes thiab cov resins hluavtaws.
Cov tshuaj reagent analytical, siv rau kev txiav txim siab ntawm cov dej noo hauv cov cawv, cov hydrocarbons saturated, benzene, chloroform, pyridine, carbon tetrachloride, thiab lwm yam.
Ntim thiab Xa Khoom
Ntim: 200kg / nruas los yog raws li cov neeg siv khoom xav tau.
Kev xa khoom: yog cov tshuaj lom neeg thiab tuaj yeem xa los ntawm tsheb ciav hlau, dej hiav txwv thiab huab cua.
Tshuag: muaj 500MTs kev nyab xeeb Tshuag
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
