Calcium Chloride yog cov ntsev ua kom tsis muaj ntxhiab tsw, lub ntsej muag yog hmoov lossis dawb-dawb, flake, prill lossis ntau, muaj Calcium Chloride anhydrous thiab Calcium Chloride dihydrate. Calcium Chloride yog siv dav hauv ntau qhov chaw lag luam vim nws lub cev thiab tshuaj. Cov ntawv sau, plua plav tawm thiab ua kom qhuav yog sib cais tsis tau los ntawm Calcium Chloride, thiab kev siv roj av thiab kev tua tsiaj, uas cuam tshuam txog kev lag luam thiab lub neej, yog sib cais los ntawm lub luag haujlwm ntawm Calcium Chloride. Yog li, Calcium Chloride ua si dab tsi hauv ob daim teb no?
Roj Drilling
Hauv kev siv cov roj, Calcium Chloride anhydrous yog cov khoom siv tseem ceeb, vim hais tias nyob rau hauv cov txheej txheem ntawm kev siv roj siv ntxiv anhydrous calcium chloride muaj cov ntawv thov hauv qab no:
1. Kho cov av nkos txheej:
Ntxiv Calcium Chloride tuaj yeem ruaj khov cov av nkos txheej ntawm ntau qhov tob;
2. Lub tshuab nqus roj: kom ntub cov drilling txhawm rau kom ua haujlwm ntawm cov mining;
3. Ua lub hau ntsaws: kev siv Calcium Chloride nrog lub siab huv kom ua lub qhov ntsaws tuaj yeem ua lub luag haujlwm ruaj khov rau ntawm cov roj kom zoo;
4. Kev Rhuav tshem: Calcium Chloride tuaj yeem tuav qee yam kev ua haujlwm ionic, cov calcium calcium chloride muaj lub luag haujlwm ntawm kev rhuav tshem tawm.
Calcium chloride siv dav hauv cov roj qhov tshij vim nws tus nqi qis, yooj yim cia thiab yooj yim siv.
Kev ua dej tsiaj
Lub hauv paus tseem ceeb siv nyob rau hauv kev aquaculture yog Calcium Chloride dihydrate, uas ua rau pH ntawm pas dej tsis zoo.
Tsim nyog pH tus nqi rau cov tsiaj dej feem ntau hauv cov dej ntses aquaculture yog qhov nruab nrab rau me ntsis alkaline (pH 7.0 ~ 8.5). Thaum pH tus nqi yog qhov tsis xws luag siab dhau (pH≥9.5), nws yuav ua rau cov kev tsis zoo xws li kev loj hlob qeeb, nce ntawm pub coefficient thiab morbidity ntawm aquaculture cov tsiaj. Yog li, yuav ua li cas txo pH tus nqi tau dhau los ua qhov tseem ceeb hauv kev ntsuas kev tswj dej hauv pas dej, thiab tseem yog qhov chaw tshawb fawb kub hauv kev tswj dej. Hydrochloric acid thiab acetic acid feem ntau siv cov kua qaub-tswj lub zog, uas tuaj yeem ncaj qha rau hydroxide ions nyob rau hauv dej kom txo tau tus nqi pH.Calcium Chloride precipitates hydroxide ions los ntawm calcium ions, thiab cov txiaj ntsig colloid tuaj yeem ua kom ncaj thiab muaj qee qhov phytoplankton, qeeb qeeb noj ntawm cov pa roj carbon dioxide los ntawm algae, yog li txo qis pH.A ntau ntawm cov kev sim tau ua pov thawj tias Calcium Chloride muaj cov txiaj ntsig zoo tshaj plaws ntawm pH degradation ntawm aquaculture pas dej piv nrog hydrochloric acid thiab acetic acid.
Thib ob, calcium chloride nyob rau hauv aquaculture kuj tseem ua lub luag haujlwm hauv kev txhim kho cov dej ua kom tawv ncauj, cuam tshuam ntawm nitrite toxicity.
