Daim zaj duab xis no tuaj yeem tiv thaiv cov dej noo, oxygen, thiab cov tshuaj corrosive kom tsis txhob nkag mus rau hauv qhov chaw ntawm cov hlau, yog li ua tiav lub hom phiaj ntawm kev tiv thaiv xeb. Tsis tas li ntawd, alkyd enamel kuj muaj kev nplaum zoo thiab tiv taus huab cua, thiab tuaj yeem tswj tau kev ua haujlwm ruaj khov hauv ntau qhov chaw ib puag ncig.
Kev sib raug zoo ntawm cov khoom ntawm cov xim alkyd enamel thiab nws txoj haujlwm tiv thaiv xeb
Tsis yog txhua cov xim alkyd enamel muaj cov xim tiv thaiv xeb, yog li lawv tsis tuaj yeem tiv thaiv xeb. Thaum siv cov xim alkyd enamel, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xyuas cov khoom sib xyaw thiab lub hom phiaj ntawm cov khoom kom ntseeg tau tias nws muaj cov yam ntxwv tiv thaiv xeb. Cov xim alkyd enamel sib txawv muaj peev xwm tiv thaiv xeb thiab lub neej ua haujlwm sib txawv, uas nyob ntawm cov xim tiv thaiv xeb uas lawv muaj thiab qhov tuab ntawm cov txheej.
Qhov sib txawv ntawm cov xim alkyd enamel thiab lwm cov xim tiv thaiv xeb
Cov xim sib nqus yog ua los ntawm cov kua roj vanish ua cov khoom siv hauv paus thiab tau npaj los ntawm kev sib tsoo hauv cov xim. Tom qab cov txheej qhuav, nws nthuav tawm cov xim sib nqus thiab muaj qhov chaw tawv. Cov hom feem ntau suav nrog phenolic magnetic xim thiab alkyd magnetic xim. Lawv yog qhov tsim nyog rau cov hlau qhov rai mesh thiab lwm yam khoom siv. Cov xim tiv thaiv xeb tuaj yeem tiv thaiv cov hlau nto los ntawm cov tshuaj lom neeg lossis electrochemical xeb los ntawm huab cua thiab dej hiav txwv. Nws yog feem ntau muab faib ua ob pawg: lub cev thiab tshuaj lom neeg tiv thaiv xeb xim. Cov xim sib nqus suav nrog zinc daj, hlau liab epoxy primer. Cov zaj duab xis xim yog tawv thiab ruaj khov, nrog kev nplaum zoo. Yog tias siv ua ke nrog ethylene phosphating primer, nws tuaj yeem txhim kho kev tiv thaiv cua sov thiab kev tiv thaiv ntsev tsuag. Nws yog qhov tsim nyog rau kev siv ua lub hauv paus rau cov khoom siv hlau hauv thaj chaw ntug dej hiav txwv thiab thaj chaw sov.
Cov xim alkyd enamel tuaj yeem suav hais tias yog cov xim tiv thaiv xeb zoo heev, tab sis tsis yog txhua cov xim alkyd enamel muaj cov yam ntxwv tiv thaiv xeb. Ua ntej siv, nws yog ib qho tsim nyog yuav tsum xaiv cov khoom kom zoo thiab ua raws li cov lus qhia rau kev siv thiab kev saib xyuas kom ntseeg tau tias nws cov txiaj ntsig tiv thaiv xeb thiab kev pabcuam lub neej.
