Nkag siab Zinc Chloride: Cov Khoom Siv thiab Cov Khoom Siv Siv

Zinc chloride yog ib qho tseem ceeb raw khoom rau kev tsim cov khoom siv tshuaj nrog ntau yam khoom thiab siv. Qhov tsab xov xwm no yuav qhia nyob rau hauv kom meej cov khoom, ntau lawm txoj kev thiab kev siv ntawm Zinc Chloride nyob rau hauv txawv teb.

1. Cov khoom ntawm zinc chloride

Zinc chloride yog xim tsis muaj xim, pob tshab, crystalline khoom nrog muaj zog hygroscopicity. Nws yog yooj yim soluble nyob rau hauv dej, thiab kuj nyob rau hauv cov organic solvents xws li ethanol, methanol, thiab acetone. Zinc chloride yog ib qho yooj yim heev rau deliquesce nyob rau hauv cov huab cua, yog li nws yuav tsum tau kom qhuav thaum lub sij hawm cia thiab siv.

Zinc chloride muaj cov tshuaj tiv thaiv siab thiab tuaj yeem ua rau muaj ntau yam hlau, tsis yog hlau, acids, alkalis thiab lwm yam khoom. Tsis tas li ntawd, zinc chloride kuj muaj thermal stability thiab corrosion kuj.

2. Cov txheej txheem ntau lawm ntawm zinc chloride

Zinc chloride tuaj yeem tsim los ntawm ntau txoj hauv kev, feem ntau yog raws li hauv qab no:

• Acid hydrolysis: ua rau zinc oxide lossis zinc carbonate nrog hydrochloric acid los tsim zinc chloride thiab dej.

• Cov tshuaj tiv thaiv ntawm cov hlau zinc nrog hydrochloric acid: Ntxiv cov hlau zinc ncaj qha rau hauv hydrochloric acid kom hnov ​​​​mob thiab tsim zinc chloride thiab hydrogen.

• Ammonium chloride txoj kev: Sib tov zinc oxide thiab ammonium chloride thiab cua sov rau lawv los tsim zinc chloride, ammonia thiab dej.

Hauv cov txheej txheem tsim khoom tiag tiag, txoj kev tsim khoom tsim nyog tuaj yeem raug xaiv raws li yam xws li cov khoom siv raw thiab cov nqi tsim khoom.

3. Kev siv cov zinc chloride

Zinc chloride muaj ntau yam kev siv hauv cov khoom siv raw rau kev tsim tshuaj. Cov hauv qab no yog qee qhov kev siv tseem ceeb:

• Catalyst: Zinc chloride tuaj yeem siv los ua ib qho catalyst rau ntau cov tshuaj tiv thaiv, xws li esterification, condensation, thiab lwm yam.

• Desiccant: Zinc chloride tuaj yeem siv los ua cov desiccant kom tshem tawm cov dej noo ntawm cov pa los yog kua vim nws cov hygroscopicity.

• Cov tshuaj electroplating: Zinc chloride tuaj yeem siv los npaj cov tshuaj electroplating thiab muab tso rau ntawm cov hlau nto thaum lub sij hawm electroplating txheej txheem los txhim kho corrosion kuj thiab zoo li zoo ntawm cov hlau.

• Preservative: Zinc chloride tuaj yeem siv los ua cov khoom khaws cia rau cov ntaub ntawv xws li ntoo thiab tawv kom ntev lawv lub neej kev pab.

Nyob rau hauv luv luv, zinc chloride plays lub luag hauj lwm tseem ceeb nyob rau hauv lub teb ntawm raw cov ntaub ntawv rau kev tsim tshuaj. Los ntawm kev nkag siab txog nws cov khoom, kev tsim khoom thiab kev siv hauv ntau qhov chaw, peb tuaj yeem ua lub luag haujlwm zoo ntawm zinc chloride thiab txhawb kev txhim kho kev lag luam tshuaj.
