Sodium carbonate yog ib qho ntawm cov ntaub ntawv lom neeg lom neeg cov tshuaj lom neeg txhua hnub, tshuaj tua tsiaj, tshuaj ntxuav tshuaj, tshuaj ntxuav tshuaj, thiab tseem siv rau hauv kev yees duab thiab tshuaj ntsuam xyuas. Nws yog ua raws Metallurgy, Textiles, Roj av, Kws Muaj Txuj Ci, Tshuaj thiab lwm yam kev lag luam. Cov iav kev lag luam yog cov neeg siv ntau tshaj plaws ntawm cov dej tshauv qab zib, kev siv 0.2 tons ntawm cov dej tshauv. Nyob rau hauv cov kev lag luam dej tshauv
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 khob
Lub hauv paus tseem ceeb ntawm cov iav yog sodium silicate, calcium silicate, calcium silicate, silicon dioxate yog cov khoom siv tseem ceeb siv los sodium silicate. Sodium carbonate reacts nrog silicon dioxide ntawm qhov kub kom ua los ntawm cov dej socium silicate thiab carbon dioxide. Sodium carbonate tseem tuaj yeem hloov kho cov coefficient ntawm kev nthuav dav thiab tshuaj lom neeg tiv thaiv ntawm lub khob. Cov sodium carbonate tuaj yeem siv los ua ntau hom iav, xws li iav zoo, thiab lwm yam
Xus npus
Raws li tus neeg sawv cev ntawm tus neeg sawv cev hauv xab npum, nws tuaj yeem txhim kho cov nyhuv ntxuav, thiab nce cov ntsiab lus ntawm cov tshuaj yeeb dej, kom cov tshuaj ntxuav tau zoo heev. Sodium carbonate muaj qee qhov tshuaj ntxuav, tshwj xeeb yog roj stains, yog acidium carbonate yog siv los ua kom lawv los tsim cov ntsev-soluble ntsev. Ntau lub xab npum ntawm kev ua lag luam ntxiv qee yam ntawm sodium carbonate, lub luag haujlwm tseem ceeb tshaj plaws ntawm cov tshuaj alkaline zoo ntawm cov tshuaj ntxuav tes ua kom zoo.
Dyeing ntxiv
1. Alkaline Action:Kev daws teeb meem sodium carbonate yog ib qho tsis muaj zog alkaline uas tuaj yeem ua rau cellulose thiab protein molecules nqa cov nqi tsis zoo. Kev tsim cov nqi tsis zoo no yooj yim rau cov adsorption ntawm cov xim sib txawv, yog li cov xim muaj peev xwm ua tau zoo dua nyob rau saum npoo ntawm cov cellulose lossis protein.
2. Txhim kho cov solubility ntawm cov xim:Qee cov pigments hauv cov dej solubility yog tsawg, sodium carbonate tuaj yeem txhim kho pigments dej tuaj yeem txhim kho los ntawm cov xim hauv cov dej tuaj yeem ua kom tau adsorbated los ntawm cellulose los yog protein.
3. Meshralizing sulfuric acid los yog hydrochloric acid:Nyob rau hauv deating cov txheej txheem, qee cov pigments yuav tsum tau hnov cov sulfuric acid los yog hydrochloric acid los ua kom tiav cov nyhuv dyeing. Sodium carbonate, raws li ib qho khoom siv alkaline, tuaj yeem cuam tshuam nrog cov tshuaj acidic no, yog li ua tiav lub hom phiaj ntawm dyeing.
Papermaking
Sodium carbonate hydrolyzes nyob rau hauv dej los tsim sodium peroxolarbonate thiab carbon dioxide. Sodium peroxacarbonate yog ib hom kev ua qias tuaj dawb, uas tuaj yeem ua tau yooj yim rau hauv dej, thiaj li ua kom tiav cov nyhuv ntawm decolorization thiab ntxuav hniav dawb.
Cov Khoom Noj Ntxiv (Khoom Noj Khoom Noj)
Raws li tus neeg sawv cev xoob xoob, siv los ua cov khoom noj, khob cij, thiab lwm yam, ua zaub mov hnav thiab muag muag. Raws li neutralizer, nws yog siv los kho cov kua zaub, xws li ua dej qab zib. Raws li tus neeg sawv cev sib xyaw, nws ua ke nrog lwm cov tshuaj los tsim cov hmoov ci sib xyaw ua ke nrog alkali ua ke nrog sodium bicarbonate. Raws li cov tshuaj tiv thaiv, siv los tiv thaiv cov zaub mov lwj lossis mildew, xws li butter, pastry, thiab lwm yam.
