Nyob rau hauv tsab xov xwm dhau los, peb tau hais txog yuav ua li cas txiav txim qhov ua tiav ntawm qhov rooj kho vajtse los ntawm qhov chaw.Lub sijhawm no peb yuav tham txog yam kev sim yuav tsum tau ua rau kev kho saum npoo.Kev ua tiav ntawm lub qhov rooj kho vajtse tsis tsuas yog cuam tshuam rau kev zoo nkauj thiab kev xav ntawm lub qhov rooj kho vajtse, tab sis kuj muaj feem xyuam rau oxidation tsis kam ntawm lub qhov rooj kho vajtse, tshwj xeeb tshaj yog nyob rau hauv cov ntug hiav txwv dej los yog thaj chaw uas muaj huab cua ntub.Yog tias qhov ua tiav ntawm qhov rooj kho vajtse tsis ua tiav zoo, nws yuav yooj yim rau oxidize thiab ua rau cov pob dawb ntawm qhov chaw.
Peb tseem yuav coj qhov rooj kov ua piv txwv nyob rau lub sijhawm no.Qhov kawg ntawm lub qhov rooj kov yog txiav txim siab los ntawm hom kev kho saum npoo ntawm lub qhov rooj kov.Txawm li cas los xij, muaj qee qhov kev sim uas yuav tsum tau ua rau txhua qhov kev kho saum npoo.
1. Tshuaj tsuag ntsev.Cov txheej txheem ntau tshaj plaws ntawm cov tshuaj tsuag tshuaj ntsev yog muab cov khoom tso rau hauv cov khoom siv tshuaj tua ntsev, thiab tshuaj xyuas qhov kev tiv thaiv corrosion ntawm cov khoom los ntawm kev tsim cov tshuaj tsw qab simulated ib puag ncig.Qhov tshwm sim ntawm qhov kev ntsuam xyuas feem ntau yog ib qho tseem ceeb qhia txog qhov durability ntawm cov khoom.Cov qauv ntsuas feem ntau yog muab faib ua 48h, 72h, 96h, thiab lwm yam. Lub sijhawm ntev dua, qhov zoo dua corrosion kuj ntawm cov khoom nto.
2. Kev kuaj dej cawv abrasion.Wrapping 500g hnyav nrog gauze, dipped nyob rau hauv ib tug 95% kev kho mob cawv tov, thiab so nws rov qab thiab tawm 50 zaug ntawm ib tug ceev ntawm 2 rov qab thiab tawm / sec nyob rau hauv ib tug 60mm ntev ntawm cov khoom.Yog hais tias cov khoom nto tsis faded raws li tsim nyog, qhov kev ntsuam xyuas yog tsuas yog los xyuas cov cawv tsis kam ntawm cov khoom nto.
Yog tias lub qhov rooj kho vajtse dhau ob qhov kev ntsuam xyuas saum toj no, nws txhais tau tias qhov chaw ntawm cov khoom no muaj lub neej ntev, thiab nws tsis yooj yim kom muaj cov pob dawb thiab xeb.Ib qho ntxiv uas yuav tsum tau hais ntawm no, yog tias qhov ua tiav ntawm lub qhov rooj kho vajtse yog cov xim pleev xim, xav tau ib qho kev sim ntxiv:kev xeem hlais.
Hla hla kev xeemyog siv cross-cut tester los kos 10 * 10 1mm * 1mm daim phiaj me me rau ntawm qhov chaw ntawm cov khoom, thiab tom qab ntawd siv 3M 600 daim kab xev los lo rau daim phiaj me me, rub tawm daim kab xev sai sai, thiab ua ob qhov kev xeem tib yam. txoj hauj lwm.Cov xim pleev xim tuaj yeem muab faib ua 5B, 4B, 3B, 2B, 1B thiab 0B.Tus naj npawb loj dua, qhov muaj zog ntawm cov xim adhesion, thiab qhov tsawg dua cov khoom yuav tev tawm.
Hnub no kev sib koom xaus ntawm no, yog tias koj xav paub ntau ntxiv txog qhov rooj kho vajtse, txais tos tuaj xyuas peb lub vev xaib.
