Hauv kev lag luam niaj hnub, hlau nto deg yog ib kauj ruam tseem ceeb hauv kev txhim kho kev ua tau zoo, txuas ntxiv lub neej pabcuam, thiab txhim kho cov tsos ntawm cov ntaub ntawv hlau. Txawm li cas los xij, cov txheej txheem hlau hlau ib txwm muaj, cov khoom hnyav thiab siv cov kuab tshuaj uas muaj kev cuam tshuam rau ib puag ncig thiab kev noj qab haus huv. Nrog kev txhim kho kev txuas ntxiv ntawm kev tswj hwm thoob ntiaj teb thiab kev tsim kho cov tshuaj ntsuab tau tshwm sim los ua cov qauv tshiab hauv kev lag luam kev lag luam.
Teeb meem ib puag ncig ntawm cov txheej txheem hlau ua cov tshuaj kho
Cov txheej txheem hlau hlau saum npoo av, xws li hexavalent chromium passivation nyob rau hauv electroplating, tau siv dav los txhim kho kom muaj cov hlau corrosion. Tab sis hexavalent chromium yog lub zog carcinogen, thiab nws cov khib nyiab thiab kev tso pa tawm ua kom muaj kev phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv. Nyob rau hauv cov txheej txheem tha xim thav duab, ntau tus naj npawb ntawm cov organic muaj teeb meem (VOCS), uas tuaj yeem tsim cov kev ua haujlwm ntawm lub cev ua pa. Tsis tas li ntawd, cov nyiaj khib nyiab loj thiab pov tseg los ntawm cov txheej txheem ib txwm muaj, yog tsis kho kom av, tuaj yeem ua rau cov av thiab cuam tshuam rau kev ua kom ecological.
Kev txhim kho keeb kwm ntawm ntsuab tshuaj siv tshuab
Nrog kev txuas ntxiv ua nruj ntawm cov kev cai ib puag ncig, xws li cov kev cai EU ntawm kev tso npe, ncav cuag), kev tso cai thiab kev siv tshuaj tsis zoo rau hauv cov hlau sib txawv. Yog tias kev lag luam tsis ua rau txheej txheem txhim kho, lawv yuav ntsib txoj kev pheej hmoo ntawm kev nplua ntau lossis ntau lawm shutdowns. Nyob rau tib lub sijhawm, kev nce ntxiv rau cov khoom lag luam ib puag ncig ntawm cov neeg siv khoom tau txais cov qauv kev ua phooj ywg ntau. Hauv cov ntsiab lus no, Green Chemistry cov txheej txheem tau yooj yim los ua kev tshawb fawb hauv kev tshawb fawb txog kev lag luam hlau nto, thiab kev nyab xeeb kom muaj kev nyab xeeb kom siab.

Chromium freelivation txheej txheem
Chromium Kev Ua Haujlwm Dawb Passivation yog ib puag ncig cov kev kho kom zoo nkauj hlau saum npoo av uas tau tsim kho sai sai nyob rau xyoo tas los no. Nws hloov cov khoom noj qab zib chromium sib txuas nrog titanium ntsev corrosion, thiab lwm yam ua tiav. Piv txwv li, cov yeeb yaj kiab passivation tsim los ntawm titanium zirconium raws cov passoriste thiab adcesion, thiab tsis muaj cov hlau hnyav, ua kom muaj dej khib nyiab yooj yim. Tus txheej txheem no tsis yog txo cov kev puas tsuaj rau ib puag ncig, tab sis kuj tseem ua tau raws li qhov yuav tsum muaj ntawm cov khoom siv hluav taws xob thiab lwm yam khoom.
Dej Raws Txheej Txheej Txheem
Dej raws txheej thev naus laus zis yog cov txheej txheem txheej txheej uas siv cov dej ua cov kuab tshuaj los yog dispersing nruab nrab. Piv nrog cov kev siv ua yeeb yam raws li cov txheej txheej, dej sib xyaw tuaj yeem txo cov pa hluav taws xob voc los ntawm ntau dua 90%, zoo heev txo cov pa phem. Dej ua cov txheej txheem muaj kev ua haujlwm zoo thiab tuaj yeem siv los ntawm ntau txoj kev xws li txau, txhuam hniav, thiab ntsw. Lawv kuj tau ziab nrawm nrawm nrawm nrawm nrawm, cov dej tsis zoo, corrosion tsis kam, thiab cov khoom zoo nkauj. Hauv kev teb cov xim hauv tsheb, dej los ntawm cov xim pleev xim thiab cov dej sib txawv hauv cov dej muaj zog tau siv, txo cov pa phem ib puag ncig hauv kev ua lag luam ntau lawm.
Tshuab Ua Tshuab Ntshav
Cov txheej txheem ntshav ntshav kho mob siv cov khoom siv ntshav ua ntu zus rau lub cev nqaij daim tawv thiab tshuaj lom neeg nrog cov khoom sib txawv ntawm cov hlau. Tus txheej txheem no tsis tas yuav siv tshuaj lom neeg tshuaj lom neeg thiab tsis tsim cov dej khib nyiab lossis pa roj thaum lub sijhawm kho mob, ua rau ib tus txheej txheem ntsuab thiab ib puag ncig zoo nkauj. Piv txwv li, ntshav nitridoning kev kho mob tuaj yeem tsim cov txheej nitride nrog cov txheej txheem hardness thiab zoo txheej txheem muaj hluav taws xob tsis muaj zog thiab kev ua haujlwm siab.
