Ua ntej txau los yog pleev xim, qhov saum npoo ntawm cov hlau yuav tsum tau hloov los ua ib zaj duab xis hloov dua siab tshiab. Conversion coatings muaj xws li phosphate coatings, passivation coatings, organic coatings, tsawg lub ntiaj teb conversion txheej, thiab sol silane coatings. Ntawm lawv, kev npaj ntawm phosphating zaj duab xis yog muab cov hlau rau hauv cov ntsev tov uas muaj cov kua qaub phosphates xws li Zn, Ni, Mn, Fe, thiab lwm yam, thiab ntxiv ntau yam khoom sib xyaw ua ke tib lub sijhawm. Tom qab kev kho tshuaj, cov hlau qhov chaw yog A phosphate hloov dua siab tshiab zaj duab xis nrog ib tug tej thickness uas yog nyuaj rau yaj nyob rau hauv dej yog tsim nyob rau saum npoo.
Lub hom phiaj tseem ceeb ntawm phosphating yog muab kev tiv thaiv rau lub hauv paus hlau thiab tiv thaiv cov hlau los ntawm corroded mus rau ib qho twg; siv los ua primer ua ntej tha xim los txhim kho cov adhesion thiab anti-corrosion peev xwm ntawm cov xim zaj duab xis txheej; kom txo kev sib txhuam hauv cov hlau txias ua hauj lwm txheej txheem Lubricating nyhuv. Tam sim no, nruab nrab-kub thiab high-temperature phosphating feem ntau yog siv rau phosphating kev kho mob nyob rau hauv tsev thiab txawv teb chaws, uas tsis tsuas yog siv ntau lub zog, siv sij hawm ntev rau kev ua, thiab muaj ntau cov sediment, tab sis kuj yuav tsum tau sealing kev kho mob. tom qab phosphating, uas nyuaj rau cov txheej txheem phosphating thiab ncaj qha cuam tshuam rau qhov zoo, tawm los lossis nqi ntawm txheej txheej. Tam sim no, cov tshuaj phosphating kua siv los kho phosphating cov ntaub ntawv steel ntawm lub khw tseem muaj ntau yam tsis xws luag, thiab kev ua haujlwm ntawm phosphating kua tseem yuav tsum tau txhim kho nyob rau hauv txhua yam.
Qhov nruab nrab kub zinc phosphating tov yog haum rau ntau yam kub thiab muaj zog corrosion kuj. Qhov siab tshaj plaws dripping lub sij hawm ntawm tooj liab sulfate tuaj yeem ncav cuag li 43 feeb, uas tshaj qhov nruab nrab nruab nrab thiab kub phosphating. Tsis tas li ntawd, kev kho ua ntej tsis tas yuav tsum tau kho qhov chaw, thiab kev kho tom qab tsis tas yuav tsum muaj kev sib khi lossis saponification sealing, thiab tsis tsim cov sediments.
