Calcium chloride (CaCl₂) yog ib qho tseem ceeb inorganic ntsev dav siv nyob rau hauv kev lag luam daim ntaub ntawv vim nws siab solubility, hygroscopicity, low-temperature antifreeze zog, thiab tshuaj stability. Hauv qab no yog nws cov kev lag luam loj siv:
1. Kev lag luam thiab kev tsim kho
Deicing thiab Antifreeze Agent:
Siv rau melting dej khov thiab daus ntawm txoj kev, tshav dav hlau khiav, thiab chaw nres tsheb hauv lub caij ntuj no los ntawm kev txo qhov dej khov ntawm cov dej khov.
Zoo dua ntsev (NaCl) thiab tsawg corrosive rau pob zeb thiab hlau.
Concrete Additive:
Accelerates thaum ntxov-theem qhob hardening, txhim kho kev tsim kho efficiency nyob rau hauv txias ib puag ncig.
Txo lub sijhawm kho, ua rau nws tsim nyog rau cov phiaj xwm xwm txheej ceev thiab kev tsim kho lub caij ntuj no.
2. Desiccant thiab Humidity Control
Industrial Gas Drying:
Siv rau dehydrating natural gas, hydrogen, oxygen, thiab lwm yam gases los tiv thaiv pipeline corrosion thiab khoom tsis ua hauj lwm.
Moisture-proof Ntim:
Ua haujlwm zoo li desiccant hauv cov thawv ntim khoom, warehouses, thiab ntim khoom noj / tshuaj tiv thaiv kev puas tsuaj.
3. Kev lag luam roj thiab roj
Drilling Fluid Additive:
Ua kom cov dej drilling ceev, stabilizes cov phab ntsa zoo, thiab tiv thaiv kev sib tsoo.
Inhibits av nplaum o, optimizing drilling efficiency.
Ua kom tiav thiab Fracturing Fluids:
Siv hauv kev ua tiav zoo thiab kev ua haujlwm stimulation los kho cov kua dej.
4. Kev lag luam tshuaj thiab kev tsim khoom
Refrigerant thiab Coolant:
Siv nyob rau hauv cov tub yees tshuab, ua zaub mov khov, thiab cov chaw sim ntsuas kub qis kom tswj tau qhov xwm txheej tsis zoo.
Dye thiab Pigment Production:
Ua raws li tus neeg sawv cev pabcuam txhawm rau txhim kho dye solubility thiab stability.
Rubber thiab Plastics Kev Lag Luam:
Muaj nuj nqi raws li tus neeg sawv cev tso tawm thiab desiccant los txhim kho cov txheej txheem ntau lawm.
5. Kev kho dej thiab kev tiv thaiv ib puag ncig
Kev kho dej khib nyiab:
Tshem tawm cov pa phem xws li phosphates thiab fluorides, kho pH, thiab txhawb kev coagulation thiab sedimentation.
Dust Control:
Txau rau ntawm qhov chaw mining, thaj chaw tsim kho, lossis txoj kev uas tsis tau tsim kho kom tshem tawm cov plua plav thiab txhim kho huab cua zoo.
6. Khoom noj khoom haus thiab tshuaj lag luam
Khoom noj khoom haus additive (E509):
Siv hauv kev tsim cheese (txhawb kev coagulation), cov khoom noj hauv kaus poom (tso kev ntxhib los mos), thiab cov dej haus ua si (electrolyte replenishment).
Ua raws li stabilizer thiab thickener los txhim kho cov zaub mov zoo nkauj.
Kev siv kho mob:
Siv nyob rau hauv cov tshuaj calcium ntxiv, hemostatic agents, thiab anticoagulant npaj.
7. Lwm yam kev siv
Tyre Ballast:
Siv los ua kua ballast hauv kev sib tw lossis cov tsheb tshwj xeeb los kho qhov hnyav tis.
Cov Khoom Siv Hluav Taws Xob:
Ntxiv rau qhov hluav taws kub-resistant coatings los yog nplaim retardants los txhim kho hluav taws kub.
Environmental thiab Safety Considerations
Corrosiveness: High-concentration calcium chloride yuav corrode hlau thiab pob zeb, yuav tsum tau siv kom raug.
Environmental Impact: Kev tso tawm ntau dhau tuaj yeem ua rau cov av salinization, yuav tsum ua raws li kev cai ib puag ncig.
Xaus
Vim nws cov versatility, calcium chloride yog indispensable nyob rau hauv deicing, ziab, roj drilling, tshuaj tsim tshuaj, thiab lwm yam teb. Cov kev tsim kho yav tom ntej yuav tsom mus rau kev txhim kho ib puag ncig tus phooj ywg (xws li, cov qauv tsim qis-corrosion) thiab nthuav dav cov ntaub ntawv muaj txiaj ntsig (xws li, cov khoom siv roj teeb tshiab).
