Corrodes fibers, daim tawv nqaij, iav, ceramics, thiab lwm yam, thiab tso tawm thaum tshav kub kub thaum yaj los yog diluted nyob rau hauv concentrated kev daws; Cov tshuaj tiv thaiv neutralization nrog inorganic acid kuj tuaj yeem tsim cov cua sov ntau thiab tsim cov ntsev ua kom zoo nkauj. Rov qab siv nrog txhuas thiab zinc, tsis yog xim hlau boron thiab silicon tso hydrogen; Kev tsis txaus siab tau tshwm sim nrog halogens xws li chlorine, bromine thiab iodine. Puas yog nag los puas tuaj yeem siv cov hlau ions los ntawm kev daws teeb meem los ua hydroxide; Nws tuaj yeem ua rau cov roj saponification, tsim cov qauv organic acid sodium ntsev thiab cawv, uas yog lub hauv paus ntsiab lus ntawm kev tshem cov roj ntawm cov ntaub.
Evenbright® 'LL tseem muab cov ntsiab lus customized: Cov ntsiab lus / Partenize / Phaj Cov Khoom Siv thiab cov khoom tshwj xeeb uas haum rau koj siv cov xwm txheej, thiab muab cov qauv dawb.

Lub ntsiab siv
1. Siv rau kev tsim cov ntawv ua thiab cellulose pulp; Nws yog siv nyob rau hauv kev tsim cov xab npum, hluavtaws xab npum, hluavtaws fatty acids thiab cov roj thiab roj zaub.
2. Cov ntawv luam luam ntawv thiab dye zas kev lag luam, cov tshuaj tiv thaiv boiling rau cov zas xim molecules txhawm rau txhim kho nws cov xim pleev xim rau nws cov xim daj thiab nrawm. Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem dyeing ntawm cov amino acid dyes, sodium hydroxide muaj qhov ua kom tawg zoo. Tsis tas li ntawd, hauv cov tshuaj tiv thaiv nruab nrab ntawm dyes thiab fibers, sodium hydroxide kuj tseem tuaj yeem tsim cov txheej txheem ntawm cov tshuaj nplaum thiab kev txhim kho cov nplaum thiab nrawm ntawm cov xim.
3. Cov tshuaj lom neeg kev lag luam rau kev tsim cov borax, sodium cyanide, formic acid, oxalic acid, phenol thiab lwm yam. Kev lag luam roj av yog siv los ua cov khoom siv roj av thiab hauv cov av roj av drilling av nkos.
4. Nws kuj tseem siv rau kev kho mob saum npoo Alumina, hlau zinc thiab hlau Tooj Liab, thiab cov tshuaj pleev, duab, dyes thiab tshuaj tua kab.
5. Khoom noj khoom noj yog siv los ua cov kua ntses rau cov citrus
6. Siv dav siv cov tshuaj tiv thaiv yooj yim. Cov qauv lus lye rau npaj thiab tsom xam. Ib qho me me ntawm cov pa roj carbon dioxide thiab dej nqus. Neutralization ntawm acid. Sodium ntsev tsim. Dav siv nyob rau hauv papermaking, kev lag luam tshuaj, luam ntawv thiab dyeing, txhuas kev kho, kev kho dej, kho mob thiab lwm yam.
7. Siv rau sodium ntsev npaj thiab saponification.
8. Siv nyob rau hauv kev tsim cov ntsev ntau si, xab npum, cov khoom siv roj hmab, ntxuav roj hmab, tshuaj dawb, tshuaj dawb thiab.
9. Hauv tshuaj pleev ib ce, cov khoom lag luam acid thiab stearic acid saponification ua lub luag haujlwm ntawm emulsifier, siv los ua daus cream, zawv plaub hau thiab lwm yam.
