Vim li cas Chelating Agent ntxiv rau Cov Tshuaj Ntxuav?

Cov dej ntxuav muag softens thiab dissolves av, los yog nkag mus rau hauv lub sab hauv ntawm lub teev, txo cov binding quab yuam ntawm av hais thiab ua rau lawv tawg deb ntawm lub nto ntawm cov khoom kom ua tiav cov nyhuv tu.
Nrog rau kev txhim kho ntawm kev tiv thaiv ib puag ncig, phosphorus-dawb yuav dhau los ua txoj hauv kev tsis muaj kev cuam tshuam rau kev lag luam tu tus neeg sawv cev. Cov emission Performance index yuav tsum tau ntxuav cov kua khib nyiab tau zoo dua thiab zoo dua. Cov tshuaj ntxuav cov pa yog tam sim no nyob rau hauv kev siv vim cov emissions tom qab uas muaj phosphorus, ammonia nitrogen, COD emissions thiab lwm yam teeb meem. Tshwj xeeb, kev siv yuav raug txwv yav tom ntej. Nyob rau hauv lub ntsej muag ntawm cov xwm txheej zoo li no, peb lub tuam txhab tsim ib qho ntsuab, phosphorus-dawb thiab ib puag ncig tus phooj ywg chelating dispersant, uas daws qhov teeb meem ntawm phosphorus-muaj chelating agents siv nyob rau hauv cov pa tshuaj ntxuav. Cov molecules tuaj yeem sib cais rau hauv H + hauv dej thiab dhau los ua Cov anions nrog cov nqi tsis zoo ntawm qhov chaw nrog cov hlau ions xws li Ca2+, Mg2+, Fe2+, Cu{{7} } nyob rau hauv cov tshuaj los tsim ib tug ruaj khov complex.
Cov molecules ntawm ntsuab phosphorus-dawb 133709 ib puag ncig tus phooj ywg chelating 90396 dispersant muaj zog adsorption zog tom qab ionized rau hauv anions nyob rau hauv dej, thiab muaj zog adsorption muaj peev xwm, ua rau particle nto muaj tib nqi, yog li ua rau electrostatic repulsion ntawm hais thiab tsis txhob particle collisions. . Qhov tshwm sim tsub zuj zuj ua rau cov khoom ua kom tawg thiab tshem tawm hauv dej.
Nws yog dav siv nyob rau hauv kev lag luam tu xws li tshuaj ntxuav txhua hnub, hlau nto tu, photovoltaic tu, kho qhov muag iav tu, PCB Circuit Court board tu, tsheb qhov chaw tu, yas tu, thiab lwm yam. txawv teb chaws yav tom ntej.
Nta:
1. Ntsuab, ib puag ncig tus phooj ywg thiab phosphorus-dawb, nws tuaj yeem hloov cov pa phosphorus-muaj chelating agents.
2. Nws muaj peev xwm chelate muaj zog thiab tuaj yeem hloov cov khoom siv EDTA series.
3. Muaj zog dispersion quab yuam los tiv thaiv deposition.
4. Tiv thaiv corrosion thiab scaling ntawm tu cov cuab yeej thiab cov kav dej.
