Cia:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Cia kom deb ntawm qhov hluav taws kub, cua sov. Lub caij txias yuav tsum tswj qhov kub siab tshaj 16 ° C, kom tsis txhob muaj kev sib zog. Thaum lub caij txias, qhov kub yuav tsum tau khaws cia siab tshaj 16 ° C los tiv thaiv / tsis txhob khov.
3. Khaws lub thawv kaw. Yuav tsum tau sib cais los ntawm oxidant thiab alkali. Kev sib tov yuav tsum zam los ntawm txhua txoj kev.
4. Siv lub teeb pom kev tawg, qhov chaw ua pa.
5. Cov cuab yeej siv tshuab thiab cov cuab yeej uas txwv tsis pub siv yooj yim los tsim cov nplaim taws.
6. Cov chaw khaws cia yuav tsum tau nruab nrog cov cuab yeej kho mob xwm txheej ceev thiab cov khoom siv vaj tse tsim nyog.

Siv:

1.Derivative: Mas siv nyob rau hauv synthetising acetic anhydride, acetic ether, PTA, VAC / PVA, CA, ethenone, chloroacetic acid, thiab lwm yam
2. Pharmaceutical: Acetic acid ua kuab tshuaj thiab tshuaj raw cov ntaub ntawv, feem ntau yog siv rau zus tau tej cov penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfamethoxazole, thiab sulfamethoxazole isoxazole, norfloxacin, ciprofloxacin, licacetylephenone salicylic acid. caffeine, thiab lwm yam.
3.Intermediate: acetate, sodium hydrogen di, peracetic acid, thiab lwm yam
4.Dyestuff thiab textile printing thiab dyeing: Feem ntau yog siv los tsim disperse dyes thiab vat dyes, thiab textile printing anddyeing processing
5. Synthesis ammonia: Nyob rau hauv daim ntawv ntawm cuprammonia acetate, siv nyob rau hauv refining syngas kom tshem tawm ib tug litl CO thiab CO2.
6. Duab: Tus tsim tawm
7. Ntuj roj hmab: Coagulant
8. Kev tsim kho kev lag luam: Tiv thaiv pob zeb los ntawm frezing9. Hauv addtin kuj tau siv dav hauv kev kho dej, hluavtaws fiber, tshuaj tua kab, yas, tawv, xim, hlau ua thiab roj hmab kev lag luam

1 Cov dej qub: hais txog cov dej nyoos yam tsis muaj kev kho cov dej ntuj lossis dej hauv lub nroog.

2 Cov dej ntshiab: Tshem tawm cov dej tsis huv hauv cov dej nyoos.

3 Kev tshem tawm ntsev: yog hais txog yang thiab anion hauv dej hauv paus tshem tawm lossis txo qis rau qee qhov dej. Txoj kev tshem cov ntsev yog distillation, electrolytic txhais txoj kev, rov qab osmosis txoj kev, ion pauv txoj kev, thiab lwm yam.

4 turbidity: yog hais txog cov dej turbidity, uas yog ib qho kev kho qhov muag uas tsim los ntawm ib qho kev ncua (suav nrog cov tshuaj colloidal) hauv dej. Unit yog sawv cev los ntawm NTU. Lub turbidity yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm seb cov dej puas muaj paug hauv qhov tsos. Tus qauv chav tsev ntawm turbidity yog teev tias turbidity ntawm 1mgsio2 yog 1 degree.

5 flocculant: Cov chaw muag tshuaj uas tuaj yeem ua rau coagulation los tsim cov condensate thiab condensate.

6 Tag nrho alkali: yog hais txog tag nrho cov khoom uas tuaj yeem nruab nrab hauv cov dej hauv dej.

7 acidity: yog hais txog tag nrho cov khoom uas tuaj yeem tshwm sim nrog cov alkali muaj zog hauv dej.

8 hardness: yog hais txog qee cov hlau ions uas yooj yim tsim cov sediments hauv dej, feem ntau yog xa mus rau calcium thiab magnesium ions.

9 conductivity conductivity: Ntawm qhov kub thiab txias, qhov chaw hla-sectional yog 1 square centimeter thiab ob-parallel electrode-rau-ob parallel electrode-rau-ob-kauj ruam electrode-rau-tus-electrode-hauv-txoj cai. Nws tuaj yeem qhia ncaj qha rau cov ntsiab lus ntsev hauv dej.

10 resistivity: Nws kuj yog ib qho taw qhia uas qhia txog cov dej conductivity. Qhov dej tsis kam ntawm cov dej ntau dua, qhov dej conductivity ntawm cov dej tsis zoo, thiab cov ions tsawg dua hauv dej. Nws chav tsev yog mΩ.cm. Nws yog countdown nrog cov conductivity. Piv txwv li: lub conductivity ntawm dej yog 0.2 μs / cm, ces nws kuj yog 1/0.2 = 5 (mΩ.cm).
