Daim ntawv thov ntau yam thiab siv sodium hydroxide

Yangzhou Everbright Tshuaj Co.Ltd.

Caustic Cov ntsiav tshuaj Soda yog ib hom Caustic dej qab zib Hydrocide, nrog tus neeg sawv cev rau cov kua ntses, tus neeg saib xyuas xim, pleev xim rau tus neeg sawv cev, tshuaj ntxuav zaub mov, xab npum thiab lwm yam

Ntau yam ntau yam. Feem ntau siv Ceustric Soda ntsiav tshuaj yog piav qhia raws li hauv qab no:

1, papermaking:

Cov khoom siv raw khoom nyoos yog ntoo lossis cov nroj tsuag nyom, tab sis kuj muaj cov khoom txiav txim siab tsis yog (liignin, thiab lwm yam). Flake alkali yog siv rau kev daws teeb meem, thiab cov fiber tsuas yog tau txais los ntawm kev tshem cov lignin los ntawm cov ntoo. Qhov tsis-cellulose tivthaiv tuaj yeem yog yaj los ntawm kev ntxiv dilute caustic soda tov, yog li ntawd cellulose raws li lub ntsiab ntawm pulp tuaj yeem npaj tau.

2, refinum:

Tom qab cov khoom siv roj hmab tau ntxuav nrog cov sulfuric acid, qee cov tshuaj acidic yuav tsum tau ntxuav nrog Tableti tov, thiab tom qab ntawd ntxuav kom tau txais cov khoom lag luam zoo.

3. Textile:

Paj rwb thiab cov ntaub ntawv raug kho nrog cov sodium sodium hydroxide (Caustic dej qab zib) kev daws teeb meem kom txhim kho cov khoom muaj fiber ntau. Cov khoom cuav xws li cov paj rwb paj rwb, cov ntaub plaub tsiaj cuav, cov ntaub qhwv ntsej muag, thiab lwm yam.

4, luam ntawv thiab dylying:

Cov ntaub qhwv paj rwb nrog cov tshuaj alkaline kho, tuaj yeem tshem tawm cov ntaub npuag hauv cov ntaub, thaum nce cov xim zoo nkauj ntawm cov ntaub, yog li ntawd cov khaub ncaws loj dua.

5, Ua xab npum:

Lub ntsiab tivthaiv ntawm cov xab npum yog cov ntsev sodium ntawm cov roj ntsha ua tau zoo, feem ntau yog ua los ntawm cov roj thiab alkali ntsiav tshuaj li cov khoom nyoos los ntawm saponification cov tshuaj tiv thaiv. Ntxiv nrog rau cov roj av ua kom zoo, xab npum tseem muaj Rosin, dej iav, txuj lom, dyes thiab lwm fillers. Kev Tsim qauv, cov roj fattey ntau dua sodium muaj cov tsis yog-polar hydrophobic part (Hydrocarbon Group) thiab ib pawg hydrophilic feem (carboxyl pab pawg). Cov pab pawg hydrophobic muaj Oloughilic cov khoom. Thaum ntxuav, cov roj hauv cov av yog do rau hauv cov pa roj me, thiab tom qab muaj cov roj av roj hmab, thiab tom qab cov roj molecules tau khi ua ke los ntawm cov van der WAsals rog. Lub Hydrophilic pab pawg (Carboxyl Group), uas yooj yim yaj hauv dej, yog ncua sab nraud cov roj poob thiab tso rau hauv dej. Lub ntsiab ntawm xab npum yog naoh, tab sis naoh tsis yog xab npum. Nws cov kua aqueous yog roj ntau thiab tuaj yeem siv ua cov xab npum. Xab npum yog emulsifier. Lub hauv paus ntsiab lus yog Saponification Ch3coch3 + Naoh = Ch3Coona + Ch3ch2oh, thiab Ch3Coona yog cov khoom siv nquag ua kom cov xab npum.

6, Kev Lag Luam Kev Lag Luam:

Ua cov pa roj hmab, cov dej electrolytic yog siv cov ntsiav tshuaj ntawm alkali. Kev tsim cov ntsev ntau inrorganic, tshwj xeeb tshaj yog kev npaj ntawm qee cov ntsev sochote, sodium dichromate, sodium sulfite, etc.) yog siv nyob rau hauv cov ntsiav tshuaj alkali. Nws tseem siv nyob rau hauv synthesis ntawm dyes, tshuaj thiab cov organic intermediates.

7, metallurgical kev lag luam:

Feem ntau los hloov cov kev nquag tiv thaiv ntawm lub ore rau hauv soluble ntsev, nyob rau hauv thiaj li yuav tshem cov insoluble impurities, yog li ntawd, feem ntau yuav tsum tau ntxiv alkali ntsiav tshuaj. Piv txwv li, hauv cov txheej txheem smelting ntawm txhuas, kev npaj ntawm cryolite thiab kev kho mob ntawm bauxite siv.

8, kev siv cov txiv qaub los txhim kho cov av:

Hauv av, vim tias cov organic teeb meem hauv cov txheej txheem decomposition yuav tsim cov organic acids, huab cua ntawm cov zaub mov tseem tuaj yeem tsim cov kua txiv hmab txiv ntoo. Tsis tas li ntawd, kev siv cov chiv hauv cov chiv xws li ammonium sulfate, ammonium chloride, thiab lwm yam, kuj tseem ua rau cov av acidic. Thov cov txiv qaub muaj peev xwm neutralize cov kua qaub hauv av, ua kom cov av kom haum rau cov qoob loo loj hlob, thiab txhawb nqa kev tawm tsam ntawm cov kab mob me me. Tom qab qhov nce ntawm ca2 + hauv av, nws tuaj yeem txhawb nqa cov hws ntawm cov av hauv av, uas yog qhov tsim kom muaj kev sib sau ua ke, thiab tib lub sijhawm, nws tuaj yeem muab cov calcin uas yuav tsum tau rau cov nroj tsuag kev loj hlob.

9. Alumina Ntau Lawm:

Naoh daws yog rhuab kom yaj alumina hauv bauxite thiab muab sodium alnoj tshuaj. Tom qab kev daws teeb meem los ntawm cov chaw seem (cov av nkos liab), qhov kub thiab txias, thiab calcined, thiab calcined rau hauv 950 ~ 1200 ℃, oxide tiav lawm. Kev daws tom qab daus ntawm Aluminium hydroxide yog hu ua niam cawv, uas yog evaporated thiab concentricated thiab rov ua dua tshiab. Vim yog cov qauv sib txawv crystalline, diaspore thiab diaspore, lawv yog qhov tsim nyog los muab sib txawv kev sib txawv ntawm cov xwm txheej, feem ntau yog sib txawv qhov kub. Lub diaspore hom bauxite yuav yaj ntawm 125 ~ 140c, thiab lub diaspore hom bauxite yuav yaj ntawm 240 ℃ thiab ntxiv rau ntawm txiv qaub (3 ~ 7%).

10, ceramics:

caustic dej qab zib hauv cov ceramic tsim lub luag haujlwm muaj ob lub ntsiab lus: ua ntej, hauv cov txheej txheem tua hluav taws ntawm ceramics, caustic dej qab zib raws li ib tug menyuam. Thib ob, cov nplaim hluav taws xob yuav kos tau kos los yog ntxuav, thiab tom qab tu nrog caustic cov dej qab zib, cov khoom sib luag ceramic yuav yog smoother.

11, Kev Tiv Thaiv:

Tus kab mob protein denaturation. Cov no feem ntau yog siv rau kev ntxuav thiab tshuaj tua fwj hauv cov kua txiv cawv.

12, Ntxiv rau rau neeg lim dej:

Muaj zog sodium oxide kom kho tus nqi pH, dej phwj tuaj, yog li ntawd cov peev txheej rov ua dua tshiab.

13, Kev Muaj Tshuaj Tso Cai, Muaj Ntxiv Ntxiv:

Ntsiav tshuaj Alkali feem ntau yog siv nyob rau hauv kev lag luam kws tshuaj rau cov kev daws teeb meem alkalize lossis kho cov lej PHQU ntawm cov tshuaj.

14, electroplating, tungsten refining.:

Cov ntsiav tshuaj alkali hauv hlau plating ua cov tshuaj electroplating daws, ua lub luag haujlwm ntawm tus neeg saib xyuas!

15, tsim cov ntaub ntawv silk, ua cov chaw ua khoom siv.

16. Kev lag luam tawv (kev ua ntawm ob siv ntawm alkali ntsiav tshuaj):

(1) Rau cov txheej txheem recycling tshauv ua kua, soak thiab ntxiv sodium sulfide aqueous daws hauv cov txheej txheem nthuav dav

Nruab nrab ntawm ob kauj ruam ntawm cov hmoov hmoov ua kom zoo, kev siv 30% siv tau rau cov khoom tawv nqaij kom ua tau zoo 0.3-0.5% yog nce rau cov khoom lag luam zoo nkauj.
(2) Raws li cov khoom nruab nrab alkaline thiab ib qho dej ntawm cov tshuaj tua kab, thiab tom qab ntawd txias txog 80 ° C Tom qab yaj tag nrho. Tom qab nplawm, ntxiv hydrochloric acid nyob rau hauv ib tug trickle, txuas ntxiv mus do rau 20 mus rau 30 feeb, thiab ntxiv tus nqi ntawm formulayde. Cia nws sov ntawm 78 ~ 80 ℃, cia nws ua kom muaj kev cuam tshuam rau kev kho mob hydroxide, thiab lim cov kua nplaum ntawm cov xov paj rau kev siv tshwj tseg.

17, Polyester Tshuaj Kev Lag Luam:

siv rau kev tsim cov formic acid, oxalic acid, boralic cyanide thiab xab npum, hluavtaws fatty acids, thiab lwm yam.

18, Textile luam ntawv thiab tawg kev lag luam:

Siv ua cov neeg sawv cev rwb, cov neeg sawv cev npau npau, muaj kev lom zem thiab cov xim txo qis, hauchang xiav zas xim.

19, smelting kev lag luam:

Siv los tsim cov txhuas hydroxide, txhuas oxide thiab hlau deg kho tus neeg sawv cev.

20, ntsuas kev lag luam,:

Siv ua cov kua qaub nruab nrab, decolorizing tus neeg sawv cev, deodorizing tus neeg sawv cev.

21, kev lag luam nplaum:

Siv raws li cov hmoov txhuv nplej siab Gelatinizer, ntawm nruab nrab.

22, tsim cov tshuaj phosphote, tsim cov khoom lag luam manganate.

23. Kev tsim kho ntawm cov roj hmab qub roj hmab.

24, tuaj yeem siv tau ua cov citrus, peach peeling tus neeg saib xyuas thiab tus neeg sawv cev tsis txaus ntseeg, deodorant.

25, ntsiav tshuaj Alkali tseem siv hauv kev ua tshuaj tua kab.
