GB/T 32373-2025, "Kev Ntsuas Cov Txheej Txheem rau Reverse Osmosis Membranes," yog tus qauv tseem ceeb hloov pauv xyoo 2015, kos lub cim tseem ceeb hauv kev ntsuas kev rov qab osmosis membrane. Cov txheej txheem no nthuav dav nws cov peev txheej kom suav nrog ntau hom membrane, xws li hauv tsev, ultra- tsis tshua muaj siab, tsis tshua muaj siab, dej tsis txaus, thiab dej hiav txwv desalination membranes. Tus txheej txheem qhia txog cov kev sim rau cov tsis tshua muaj siab rov qab osmosis daim nyias nyias: sodium chloride concentration 1500 ± 20 mg / L, ntsuas siab 1.03 ± 0.02 MPa, thiab siv dej flux 20 ~ 25 L / (m²·h). Tsis tas li ntawd, tus qauv tshiab ntxiv peb pawg ntawm fouling resistance tests, ua tiav kev txhim kho tus qauv siv tau thiab nce qib.
Industrial low-pressure membranes yog siv dav hauv kev kho dej hauv dej. Lawv yog siv rau kev siv dej, dej khib nyiab, thiab dej phwj kho hauv ntau yam lag luam, suav nrog hluav taws xob, nroog, hlau metallurgy, petrochemical, thee chemical, papermaking, food, and pharmaceutical. Ntawm cov no, ultra-tsis tshua muaj siab fouling- tiv thaiv rov qab osmosis daim nyias nyias yog dav siv hauv cov dej hauv nroog thiab dej hiav txwv desalination pretreatment, txo qis kev siv zog siv. Hauv kev npaj hluav taws xob - qib dej ultrapure, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov dej tsis kam ntawm 18.2 MΩ·cm, ua rau nws tsim nyog rau kev lag luam xws li semiconductors.
