Khoom siv
MAIN SIV
1. Siv rau kev tsim cov ntawv ua thiab cellulose pulp;Nws yog siv nyob rau hauv zus tau tej cov xab npum, hluavtaws detergent, hluavtaws fatty acids thiab refining ntawm tsiaj thiab zaub roj.
2. Kev lag luam textile luam ntawv thiab dyeing yog siv los ua tus neeg sawv cev desizing, tus neeg sawv cev kub hnyiab thiab mercerizing tus neeg sawv cev rau cov ntaub paj rwb, thiab sodium hydroxide feem ntau yog siv los ua kom txo qis thiab sib txuas cov tshuaj tiv thaiv ntawm cov xim molecules los txhim kho nws cov dyeing thiab ceev ceev.Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem dyeing ntawm amino acid dyes, sodium hydroxide muaj ib tug zoo dyeing nyhuv.Tsis tas li ntawd, nyob rau hauv cov tshuaj tiv thaiv ntawm dyes thiab fibers, sodium hydroxide tuaj yeem tsim cov txheej txheem oxidation ruaj khov ntawm cov fiber ntau, yog li txhim kho qhov adhesion thiab ceev ntawm cov xim.
3. Kev lag luam tshuaj rau kev tsim cov borax, sodium cyanide, formic acid, oxalic acid, phenol thiab lwm yam.Kev lag luam roj av yog siv los kho cov khoom siv roj av thiab hauv cov roj av drilling av nkos.
4. Nws kuj yog siv rau kev kho deg ntawm alumina, hlau zinc thiab hlau tooj liab, nrog rau iav, enamel, tawv, tshuaj, dyes thiab tshuaj tua kab.
5. Cov khoom noj khoom haus yog siv los ua kua qaub rau hauv kev lag luam khoom noj khoom haus, tuaj yeem siv los ua tev tus neeg sawv cev rau citrus, txiv duaj, thiab lwm yam., kuj tseem tuaj yeem siv los ua cov tshuaj ntxuav tais diav, cov kaus poom thiab lwm cov ntim khoom, nrog rau decolorizing tus neeg sawv cev. , deodorizing tus neeg sawv cev.
6. Siv dav siv cov tshuaj analytical reagents.Standard lye rau kev npaj thiab tshuaj xyuas.Ib qho me me ntawm carbon dioxide thiab dej nqus dej.Neutralization ntawm acid.Sodium ntsev manufacturing.Dav siv nyob rau hauv papermaking, tshuaj lom neeg kev lag luam, luam ntawv thiab dyeing, tshuaj, metallurgy (aluminium smelting), tshuaj fiber ntau, electroplating, dej kho, tail gas kho thiab lwm yam.
7. Siv los ua neutralizer, masking agent, precipitating agent, precipitation masking agent, nyias txheej tsom xam txoj kev los txiav txim ketone sterol xim tus neeg sawv cev.Siv rau sodium ntsev npaj thiab saponification tus neeg sawv cev.
8. Siv nyob rau hauv kev tsim ntau yam sodium ntsev, xab npum, pulp, xov paj paj ntaub, txhob lo lo ntxhuav, viscose fiber, roj hmab khoom regeneration, hlau tu, electroplating, bleaching thiab hais txog.
9. Nyob rau hauv cov tshuaj pleev ib ce, cov khoom no thiab stearic acid saponification plays lub luag hauj lwm ntawm emulsifier, siv los ua daus cream, tshuaj zawv plaub hau thiab lwm yam.
