SWD969 Hlau anticorrosion txheej
Cov khoom siv dav siv
Kev tiv thaiv corrosion tiv thaiv roj av, tshuaj lom neeg, tsheb thauj mus los, kev tsim kho, hluav taws xob fais fab thiab lwm yam lag luam, tshwj xeeb tshaj yog cov tso tsheb hlau luam, cov cuab yeej siv tshuaj, cov qauv hlau, cov khoom siv kos duab (xws li cov khoom siv hluav taws xob), lub ru tsev thiab cov phab ntsa ntawm cov chaw tsim khoom thiab chav cia khoom.
Khoom nta thiab qhov zoo
* Zoo heev corrosion kuj, nyias txheej kuj ua lub luag hauj lwm ntawm tuab zaj duab xis txheej.
Nrog zoo adhesion thiab tsis tshua muaj kev kho deg yuav tsum, nws tuaj yeem siv ncaj qha rau saum npoo ntawm cov hlau ua haujlwm, uas tsis tsuas yog muaj cov nyhuv primer, tab sis kuj muaj cov haujlwm ntawm txheej txheej sab saum toj.
Cov txheej yog tuab thiab tawv, uas tuaj yeem tiv thaiv kev puas tsuaj rau kev ntxhov siab.Cov khoom siv zoo heev, hnav tsis kam, cuam tshuam tsis kam thiab khawb tsis kam.Kev ua haujlwm zoo heev los tiv thaiv corrosion, tiv taus yaig thiab kev puas tsuaj ntawm ntau yam tshuaj lom neeg corrosion media, xws li tshuaj tsuag ntsev, kua qaub los nag, thiab lwm yam. Zoo heev aging kuj, tsis tawg thiab tsis muaj pulverization rau sab nraum zoov siv.Cov txheej tuaj yeem cuam tshuam lub teeb thiab cua sov hauv lub hnub kom ua tiav cov txiaj ntsig ntawm kev ua kom txias thiab txuag hluav taws xob.Nws muaj peev xwm ua tau los tiv thaiv hluav taws xob zoo li qub los ntawm kev sib sau ua ke.Ib qho khoom siv sib xyaw, cov txheej txheem tes siv tau yooj yim siv thiab tuaj yeem siv rau ntau hom kev thov.
