Daim ntawv thov ntawm cov hlau tshwj xeeb hauv dej hiav txwv desalination teb:
Cov khoom siv thiab cov ntaub ntawv siv rau hauv cov txheej txheem desalination dej hiav txwv yuav tsum muaj cov yam ntxwv tiv taus corrosion, thiab cov ntsiab cai xaiv thiab tsim cov ntaub ntawv nyob ntawm qhov chaw ua haujlwm ntawm cov ntaub ntawv. Stainless hlau tau dhau los ua cov khoom siv zoo tagnrho vim nws tiv taus corrosion thiab durability, thiab yog siv rau hauv ntau txoj kev desalination.
Vim tias dej hiav txwv muaj ntau cov tshuaj corrosive, thiab lub plhaub, lub twj tso kua dej, evaporator thiab cov kav dej kub siab uas xav tau rau kev tsim cov khoom siv dej hiav txwv desalination yog txhua qhov chaw uas sib cuag ncaj qha nrog dej hiav txwv concentration siab, thiab yuav tsum muaj kev tiv thaiv corrosion muaj zog, yog li cov hlau carbon dav dav tsis haum rau kev siv. Txawm li cas los xij, super austenitic stainless hlau, super duplex stainless hlau thiab txias dov titanium muaj kev tiv thaiv corrosion dej hiav txwv zoo heev, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm dej hiav txwv desalination engineering, thiab yog cov ntaub ntawv zoo tagnrho rau ntau yam kev cuam tshuam distillation thiab rov qab osmosis desalination nroj tsuag.
