Yog vim li cas Rust Converters tsis pab
Scars adorn ib tug txiv neej, tab sis tsis yog lub tsheb lub cev, tshwj xeeb tshaj yog thaum chips thiab khawb ntawm cov paintings ncav cuag hlau, thiab nws pib oxidize intensive. Yog li ntawd, muaj cov kab mob ntawm corrosion nyob rau hauv daim ntawv ntawm liab me ntsis thiab streaks, uas, ntawm chav kawm, spoil lub tsos ntawm lub tsheb. Txawm li cas los xij, qhov no tsuas yog ib sab ntawm qhov teeb meem ...
Yog tias cov txheej txheem corrosion tsis raug tso tseg rau lub sijhawm, tom qab ntawd dhau sijhawm qhov no yuav ua rau pom los ntawm qhov hauv lub cev thiab ua rau nws lub zog tsis muaj zog. Ntxiv mus, qhov teeb meem tshwj xeeb tshaj yog nyob rau hauv cov tsheb laus, raws li txoj cai, nrog kev khiav zoo. Lawv lub cev muaj ntau qhov chaw ntawm corrosion, nrog rau cov nyob rau ntawm qhov chaw ntawm lub cev. Yog tias kev ntsuas tsis tau ua raws sijhawm, ces cov ntsiab lus vuam thiab cov seams txuas rau ib leeg yuav poob lub zog thiab lub cev yuav pib sib kis. Yog li ntawd, kev tiv thaiv raws sij hawm yog qhov tseem ceeb hauv kev tawm tsam corrosion. Nws yog ib txwm yooj yim dua los tshem tawm me me "liab kab" dua li kho lub qhov.
Yuav ua li cas nres thiab ua kom zoo corrosion? Rau cov hom phiaj no, tshwj xeeb cov tebchaw yog siv - xeb converters. Lawv yog ib hom active compound, uas nkag mus rau hauv cov tshuaj tiv thaiv nrog oxides ntawm ob / trivalent hlau (qhov tseeb, xeb), tsim ib tug insoluble complex ntawm hlau phosphate ntsev. Txhua yam yog meej thiab yooj yim…. Tab sis tsuas yog thaum xub thawj siab ib muag. Kev xyaum qhia tau hais tias qhov sib xyaw ua ke sib txawv.
Muaj ntau ntau nuances, ib qho thiab qhov tseem ceeb tshaj plaws ntawm lawv yog impregnating zog ntawm cov khoom. Nws nyob ntawm qhov no yuav ua li cas ua tib zoo txhua qhov chaw ntawm corrosion yuav raug tshem tawm. Qhov khoom yog tias xeb muaj cov qauv xoob, uas yuav tsum tau ua tib zoo impregnated thiab neutralized kom corrosion tsis tshwm sim nws tus kheej dua. Nws yog nyob rau hauv qhov kev sib tw no uas txawv kev npaj qhia lawv cov khoom ua haujlwm thiab cov khoom zoo. Ntawm chav kawm, nws yog ib qho nyuaj rau kev ntsuam xyuas zoo npaum li cas cov muaj pes tsawg leeg impregnated thiab, yog li, neutralized xeb. Tsuas yog lub sijhawm yuav qhia ntawm no.
Txhawm rau kom tsis txhob muaj kev pheej hmoo tsis muaj txiaj ntsig, peb xav kom koj mloog cov lus qhia ua pov thawj. Ntawm ntau yam kev sib xyaw ntawm kev muag khoom, cov cuab yeej nkag mus tau zoo yog qhov txawv, piv txwv li, los ntawm xeb hloov pauv nrog zinc los ntawm ASTROhim. Nws nkag mus rau tag nrho qhov tob ntawm oxides (txog 100 microns) thiab nres cov txheej txheem ntawm hlau oxidation. Nyob rau tib lub sijhawm, zinc muaj nyob rau hauv nws cov muaj pes tsawg leeg txhim kho cov khoom ntawm cov tshuaj thiab muab kev tiv thaiv electrochemical (cathodic) ntxiv rau cov hlau. Active ions, tso rau ntawm qhov chaw kho mob, hnov mob nrog oxidizing tus neeg sawv cev, noj lub tshuab. Thiab txawm hais tias nws tsis yog panacea rau corrosion, nws tiv nrog nws lub luag haujlwm zoo kawg nkaus.
