Nrog cov thev naus laus zis tshiab xws li cov neeg hlau tsim khoom thiab Is Taws Nem kev lag luam, cov txheej txheem tshiab xws li cov neeg siv tshuab electrostatic txau, kev kho lub ntsej muag laser, kev cog cov ion thiab cov yeeb yaj kiab molecular tau nce zuj zus hauv kev kho tsheb qhov chaw kho tsheb, thiab tag nrho cov txuj ci theem ntawm kev lag luam yuav nkag mus rau qib tshiab.
Kev faib pawg ntawm cov khoom siv kho qhov chaw kho tsheb
Tam sim no, muaj ntau dua 1000 lub tuam txhab koom nrog hauv kev kho saum npoo ntawm qhov pib tsheb hauv Suav teb. Cov lag luam feem ntau tau faib tawm hauv Hiav Txwv Bohai, Yangtze River Delta, Pearl River Delta thiab nruab nrab Hubei, qhia txog qee yam ua haujlwm.
Hais txog kev lag luam nplai, kev lag luam feem ntau yog cov lag luam me thiab nruab nrab. Ntawm cov tuam txhab koom nrog hauv kev kho tsheb ntu ntu, feem ntau ntawm lawv muaj peev txheej sau npe tsawg dua 10 lab yuan.
Tam sim no, cov txheej txheem thev naus laus zis kho mob ntawm cov khoom siv kho tsheb sab hauv hauv tsev tseem muaj kev cuam tshuam los ntawm kev siv hluav taws xob ib txwm, electrophoresis, phosphating, passivation blackening, carburizing thiab nitriding, thiab daim ntawv thov kev faib ua feem ntawm cov txheej txheem kho tshiab saum npoo av xws li lub zog siab nqaj nto ntxiv dag zog, Kev txau ntshav, nplaim nano ntxiv dag zog rau thiab kev sib xyaw ua kom muaj zog thev naus laus zis tseem qis, Cov txheej txheem txheej txheem ntawm kev lag luam tseem muaj chav zoo rau kev txhim kho.
