Cov khoom siv kho dej muaj qhov ua tau zoo thiab hnav tsis kam, thiab tsim nyog rau kev lim dej thiab dej phwj kho. Nws adsorption tus nqi nce mus txog 30%, ntsev thiab alkali solubility Tsawg dua los yog sib npaug li 4%, pom tus nqi tuaj yeem ncav cuag 20, thiab nws muaj kev ua haujlwm siab thiab acid thiab alkali tsis kam. Cov khoom siv tshwj xeeb yog 3 hli, porosity 52%, thiab nws tuaj yeem siv tsis muaj hluav taws xob. Cov kev pabcuam kev cai kuj muaj.
Cov khoom siv kho dej yog cov cuab yeej siv rau cov dej muag muag hauv cov chaw muag tshuaj, zaub mov thiab lwm yam lag luam. Lawv tsuas yog siv hauv chav boilers, dej kub boilers thiab exchangers. Lawv ua tiav cov dej softening los ntawm adsorbing calcium thiab magnesium ions hauv dej los ntawm ion txauv resin. Cov resin yog regenerated los ntawm kev hloov nrog NaCl tov. Cov fiberglass resin tank siv nyob rau hauv tag nrho cov dej tsis siv neeg softeners feem ntau yog ua los ntawm siab -cov ntaub ntawv ua tau zoo thiab iav fiber ntau. Nws muaj cov yam ntxwv ntawm corrosion kuj, lub teeb yuag thiab siab zog. Kev ua haujlwm siab feem ntau yog 0.15Mpa-0.6Mpa, thiab kev ua haujlwm kub yog 5-50℃. Nws cov thev naus laus zis tuaj yeem muab faib ua kev kho inlet thiab kev kho qhov taw tes ntawm kev siv raws li daim ntawv thov scenario. Qee cov qauv tsim yuav siv cov cuab yeej tswj kev khiav dej num thiab cov khoom ntsuas dej kom zoo.
