Tam sim no, iav thiab iav sib sib zog nqus ua kev lag luam hauv Suav teb tab tom txhim kho sai. Hauv cov txheej txheem tsim cov kua qaub etching thiab frosting ntawm iav, hydrofluoric acid feem ntau yog siv los ua cov khoom siv raw khoom. Hauv kev kho cov dej khib nyiab tom qab hydrogen fluoride corrodes polycrystalline silicon, nws yuav tsim cov kua qaub ntxuav cov dej khib nyiab thiab ntxuav cov dej khib nyiab uas muaj hydrogen fluoride. Cov kua qaub ntxuav cov dej khib nyiab yuav muaj ntau dua 100000 ppm lossis ntau dua cov fluoride ions, thiab cov dej khib nyiab yuav muaj ntau pua lossis ntau dua fluoride ions, uas ua rau muaj cov tshuaj fluoride siab heev hauv cov dej khib nyiab thiab yooj yim fluorine pollution. Nyob rau hauv xyoo tas los no, lub tuam tsev tiv thaiv ib puag ncig tau nce cov kev cai nruj rau ib puag ncig thiab cov qauv dej zoo, xav tau cov nroj tsuag tshuaj kom huv huv fluorinated dej khib nyiab kom muaj cov fluoride ion cov ntsiab lus qis dua 10mg / L ua ntej nws tuaj yeem tso tawm. Yog li ntawd, nws yog ib qho tseem ceeb kom tshem tawm cov tshuaj fluoride los ntawm cov dej khib nyiab fluorinated hauv cov iav sib sib zog nqus ua kev lag luam.
Cov teeb meem hauv kev kho cov tshuaj fluoride uas muaj cov dej khib nyiab hauv iav ntau lawm:
Qhov qis dua cov ntsiab lus fluoride hauv cov dej khib nyiab, Nyab Laj ntau dua nws. Txoj kev kho mob ib txwm siv calcium ntsev los nag, uas feem ntau yog siv cov tshuaj fluoride thiab calcium los tsim cov calcium fluoride precipitates me ntsis soluble. Cov txheej txheem calcium ntsev nag lossis daus muaj kev kho mob tsis zoo ntawm cov dej khib nyiab uas tsis muaj fluoride, vim tias nws nyuaj rau tsim cov khoom siv lead ua los ntawm cov nag lossis daus hauv cov dej tsis muaj fluoride.
Yog tias cov dej khib nyiab iav xav ua kom tau raws li cov qauv tso tawm rau cov ntsiab lus fluoride, nws tuaj yeem ua tau raws li kev siv cov tshuaj fluoride tshem tawm. Cov tshuaj fluoride tshem tawm rau cov iav dej khib nyiab tuaj yeem txo cov fluoride cov ntsiab lus hauv iav dej kom sai thiab ruaj khov.<0.2mg/L. They are not only suitable for glass wastewater, but also for surface treatment of metals such as coal-fired thermal power plants, coal chemical industry, coking wastewater, stainless steel cleaning, photovoltaics, rare earths, metallurgy, mining, aluminum and aluminum products, as well as advanced treatment of various industrial wastewater such as semiconductors, panel production, fertilizers, chemicals, electroplating, etc.
Cov yam ntxwv thiab qhov zoo ntawm cov tshuaj fluoride tshem tawm cov iav dej khib nyiab:
Efficient: Sib sib zog nqus fluoride tshem tawm tus neeg saib xyuas, tsom rau kev kho cov tshuaj fluoride uas tsis muaj cov dej khib nyiab. Cov dej ntws tawm ruaj khov thiab ua tau raws li tus qauv tsawg dua 0.2mg/L, nrog rau ntau yam teebmeem xws li kev tshem tawm fluoride, coagulation, thiab pH tswj;
Cov tshuaj fluorine tshem tawm tau zoo: siab purity, tsawg npaum li cas, cov ntsiab lus sludge tsawg, tsis muaj hardness, siv ntev yuav tsis ua rau scaling, blockage thiab lwm yam tshwm sim nyob rau hauv pipelines thiab valve lub cev;
Yooj yim rau siv: Tsis tas yuav hloov cov txheej txheem dej nyoos, tsis tas yuav ntxiv cov khoom siv loj, tsis tas yuav muaj kev debugging nyuaj, cov tshuaj tiv thaiv ceev ceev, thiab kev ua haujlwm yooj yim;
Economy: Kev ua haujlwm siab, kev siv cov khoom siv tsawg, thiab tus nqi qis ntawm kev kho ib tuj dej.
