Caustic sis dej qab zib

Cov lus piav qhia luv luv:

Caustic sis dej qab zib yog cov khoom dawb nrog muaj zog hygroscopicity. Nws yuav yaj thiab ntws tom qab kev nqus noo. Nws tuaj yeem nqus dej thiab carbon dioxide nyob rau hauv huab cua los tsim sodium carbonate. Nws yog brittle, soluble hauv dej, haus dej cawv, glycerin, tab sis insoluble hauv acetone. Thaum tshav kub kub ntau tso tawm. Cov kua aqueous yog nplua thiab alkaline. Nws yog xeb heev thiab tuaj yeem hlawv cov tawv nqaij thiab rhuav tshem cov ntaub so ntswg. Sib cuag nrog aluminium ntawm qhov kub siab tshaj tawm ua cov khoom siv hydrogen. Nws tuaj yeem ua kom sib xyaw nrog cov kua qaub thiab tsim kom muaj ntau hom ntsev. Cov kua dej ua kua sodium hydroxide (piv txwv li, soluble alkali) yog kua-xim xiav ua kua nrog cov xus xaim thiab ntxig xav, thiab nws cov khoom zoo li khoom alkali.
Qhov kev npaj ntawm caustic sis dej qab zib yog electrolytic lossis tshuaj. Kev siv tshuaj lom neeg suav nrog kev ua kua qaub ua rau lub cev tsis muaj mob lossis ferrite.
Kev siv cov caustic sis dej qab zib yog siv hauv cov xab npum hluavtaws, xab npum, papermaking; kuj siv los ua cov kuab tshuaj rau vat dyes thiab insoluble nitrogen dyes; kuj siv rau hauv kev tsim cov roj av, tshuaj fibers thiab rayon; kuj siv rau hauv cov tshuaj, xws li cov khoom lag luam ntawm vitamin C Tos. Nws kuj tseem siv tau hauv cov organic synthesis thiab roj av kev lag luam thiab siv ncaj qha ua desiccant.


Khoom Nthuav dav

Cov khoom lag luam

Tooj liab sulfate yog cov siv lead ua xim xiav pob zeb, nplua xim hauv dej thiab diluted acetic acid. Kev daws tshwm sim li cov tshuaj acidity tsis muaj zog. Nws yuav yog effloresces maj mam nyob rau hauv huab cua qhuav, thiab nws saum npoo yuav dhau los ua tshuaj dawb.

Tooj liab sulfate yuav plam plaub qhov dej ntshiab thaum muab kho kom sov li 110 ° C, thiab yuav hloov mus ua dawb Copper sulfate anhydrous uas yooj yim nqus dej thaum qhov kub siab tshaj 200 ° C.

1) Kev hloov kho reagent hauv kev lag luam tsuas; kev lag luam electroplating; reagent hauv kev npaj cov tshuaj pleev xim nruab nrab; mordant hauv dyeing; khaws cia ntawm ntoo thiab lwm yam.

2) Siv dav hauv kev lag luam pub khoom noj ntxiv pub ntxiv Kev txhim kho ntawm tooj liab tsis txaus hauv tsiaj;

3) Siv dav hauv kev ua liaj ua teb raws li chiv; fungicides; tshuaj tua kab; kev loj hlob kev loj hlob rau kev tua cov npua thiab cov broiler qaib thiab lwm yam

Copper Sulphate yog siv rau kev rho tawm lwm tus tooj liab, kuj yog siv los ua cov ntxig mordant, tshuaj tua kab ua liaj ua teb, fungicides, thiab rau kev kho dej. Raws li mordant rau paj rwb thiab lo lo ntxhuav; siv los tsim cov xim ntsuab thiab xiav; siv raws li tshuaj tua kab, bactericide rau dej, antiseptics rau ntoo, catalyst rau tannage, electrocopper, roj teeb. carving thiab hais txog; siv nyob rau hauv kev lag luam mining thiab raws li raw cov ntaub ntawv ntawm lwm yam tshuaj lom neeg.

1. Siv rau kev tsim cov ntawv thiab cellulose pulp.

2. Siv rau kev tsim cov tshuaj ntxuav tes, xab npum hluavtaws, roj ua hluavtaws.

3. Siv raws li daim ntaub desizing tus neeg sawv cev, tus neeg saib xyuas scouring thiab silk polish tus neeg sawv cev hauv textile luam ntawv.

4. Siv rau hauv kev tsim cov tshuaj borax, sodium cyanide, formic acid thiab lwm yam hauv kev lag luam chemical.

5. Nws suav tias yog qhov tseem ceeb ua rau cov khoom lag luam muaj ntau cov tshuaj muaj txiaj ntsig zoo (ntau dua 30% cov caustic ntau lawm mus rau hauv daim ntawv thov no).

6. Cov tshuaj tua kab mob xws li xim pleev xim, iav thiab ceramics thiab siv hauv kev tsim cov roj thiab tshuaj pleev ib ce kuj tseem ceeb heev.

7. Cov ntawv, pulp thiab cellulose kev lag luam yog cov neeg siv loj ntawm caustic dej qab zib.Lub thaj chaw uas caustic yog qhov tseem ceeb yog: kev lag luam khoom noj khoom haus, kev kho dej (rau cov flocculation ntawm hnyav hlau thiab acidity tswj), cov xab npum thiab xab npum cov nplais, textile cov roj (ua ib tus neeg saib xyuas tshuaj dawb), cov roj ntxhia (npaj cov roj thiab roj ntxiv) thiab cov hluavtaws fiber ntau hluavtaws

8. Txog plaub feem pua ​​ntawm kev cog qoob loo yog siv nyob rau hauv cov txheej txheem ntawm kev txhim kho txhuas los ntawm nws cov aux bauxite.

9. cov seem ntawm cov kev ua qoob loo ntau dua (ntau dua 17%) muaj cov ntawv thov hloov tshiab, zoo li kev sib txuas ntawm cov kws tshuaj, cov roj hmab thim rov qab thiab kev cuam tshuam ntawm cov kua qaub.
