Kev siv 1,4-dioxane yog dab tsi?

[Siv 1] 1,4-dioxane yog siv los ua cov kuab tshuaj rau cellulose acetate, resin, zaub roj, ntxhia roj, soluble dyes, thiab lwm yam, thiab yog siv los ua tshuaj tsuag xim, kua roj vanish, plasticizer, lubricant, thiab lwm yam. . Cov roj zaub, roj ntxhia, cov dyes soluble, thiab lwm yam, thiab yog siv los ua cov tshuaj tsuag, kua roj vanish, plasticizer, lubricant, thiab lwm yam. extractant hauv kev tsim cov tshuaj zoo tshwj xeeb xws li tshuaj, tshuaj pleev ib ce, thiab tshuaj tsw qab, nrog rau kev tshawb fawb tshawb fawb. Hauv Nyij Pooj, cov khoom no feem ntau yog siv los ua tus stabilizer rau 1,1, 1-trichloroethane, nrog rau qhov ntxiv ntawm 2.5-4%; thib ob, nws yog dav siv los ua cov tshuaj tiv thaiv hnyav rau polyurethane hluavtaws tawv, amino acid hluavtaws tawv, thiab lwm yam. Cov khoom no muaj peev xwm ua kom muaj zog, zoo ib yam li dimethylformamide, thiab muaj zog dua li tetrahydrofuran. Kev siv cov tshuaj dioxane hauv qab no yog tsim nyog:
(1) Nws tsim ib txoj hauv kev nrog sulfur trioxide thiab tuaj yeem siv los ua tus neeg sawv cev sulfating hauv kev sib txuas ntawm ntau lub tebchaw;
(2) Nws yog siv rau kev rho tawm cov tshuaj thiab tshuaj tua kab, dewaxing roj av, thiab lwm yam.;
(3) Nws yog siv los ua dispersant rau dyes, dispersants rau wood colorants, thiab solvents rau roj-soluble dyes;
(4) Nws yog siv los ua tus neeg ua haujlwm siab purity hlau saum npoo, thiab lwm yam. Cov khoom no yog khaus rau ntawm daim tawv nqaij, lub ntsws, thiab cov mucous membranes. Cov tshuaj lom hnyav tuaj yeem ua rau lub siab thiab lub raum puas.
