Iipeyinti Ubushushu-resistant, metal: iintlobo kunye nesiqulatho

iimveliso yepeyinti Resistant ezilungiselelwe unyango umphezulu metal, Usebenzela ukukhusela izakhiwo ezahlukeneyo kwimiphumo eyonakalisayo nokumelana okubangelwa iikhemikhali yemozulu kwenzeka phantsi kweemeko zokusebenza kwiqondo lobushushu ephakamileyo ngumsindo. Ukuba neendonga ayiqabe i paint eqhelekileyo emlilweni mveliso kunye nemibhobho, radiator ekhaya okanye naziphi na ezinye izixhobo, phantsi kwempembelelo ngokushushubeza ukuwa ukutyabeka umaleko ngasemva kwamanzi, kunye nentsimbi Wayechanabeka. Kusenokubakho ngaphantsi anokuwuchitha intsimbi, kodwa emibi ukusuka kwindawo yobuhle lwembono, isenzeko - yellowing le yepeyinti.

Okwangoku, kushishino yemichiza uvelisa iintlobo ezininzi inks ubushushu-resistant eyenzelwe ngenxa yokudweba imiphezulu isinyithi, kuxhomekeka kokusingqongileyo iqondo lobushushu apho aya kusebenza imveliso omnye okanye omnye.

Le eliphakathi apho umphezulu but is ndinobushushu lobushushu ka-80 ° C, evumela ukusetyenziswa kwalo naluphi na ipeyinti.

Ubushushu-enganyangekiyo ipeyinti ngenxa metal, lenziwa okusekelwe alkyd kunye acrylic emahlamvini, esetyenziswa zentlelo yokudaya ekucaca ukuba amaqondo ukuya ku-100 ° C, iqulathe i ongeziweyo ubushushu-enganyangekiyo ezizodwa ethintela yellowing lwe kumphezulu xa itshiswe. Ngokuqhelekileyo, le hlobo isetyenziselwa amabala radiators zasekhaya kunye neenkqubo namanzi ashushu.

Kuba Umbala kwemiphezulu iindlela ezahlukeneyo izakhiwo nezinto zokusebenza kwiqondo lobushushu ukuya kwi-120 ° C. besebenzisa ipeyinti ubushushu-resistant ukuba metal, wenza usebenzisa i primer epoxy kwakunye ne kongezwe macandelo nezinki nezinki-phosphate. Epoxy wayesebenzisa nazo zisetyenziswa kumaqondo obushushu aphezulu - up ku 200 ° C.

Xa ulawulo ubushushu Kucetyiswa ukuya kwi-400 ° C ukuba usebenzise omnye-component ukutyabeka, undoqo equlethe ethyl silicate kunye epoksiefirnye resin. Kule lobushushu, zombala eqhelekileyo nokudinwa kwenzeka kweso, ngoko eli ipeyinti ubushushu-enganyangekiyo iqulethe metal kumafa yayo ngumgubo yesinyithi. Le ukwahluka linokusetyenziswa inqaku umaleko ube mnye.

Xa iimeko zokusebenza, imveliso okanye isakhiwo lobushushu isukela ku 650ºC, iingcali bacebisa ukuba kusetyenziswe icandelo ukutyabeka olunye, undoqo equlethe abicah nentlaka. Xa kunjalo, ipeyinti ubushushu-enganyangekiyo isicelo kumphezulu ngemethali okanye umaleko obhityileyo kakhulu ukuba ixabiso ukusuka microns-30 ukuya 100.

Isigqibo sokwahlulwa lobushushu elingaphaya 650ºC kubandakanya ukusetyenziswa njengendlela ukutyabeka izinto Umbala eyenziweyo ngokusekelwe iglasi ubushushu-ukumelana nezinto ahlanganisiweyo.

ngeo for umbala iimveliso ebuntsimbi ababandakanyekayo iimeko lobushushu eliphezulu, yiba ukumelana eliphezulu lingonakali, ziziimfidi kusenziwa irubhrikhi, ngokukhuselekileyo kwendalo, ixesha elide. Inokusebenziseka ukuya kumphezulu njengoko kwigumbi evaliweyo, nangaphandle. Bobubi ukusebenzisa i-inki ubushushu-enganyangekiyo iquka indlela yokusebenzisa - iipeyinti data, umzekelo ipeyinti epoxy , metal, isicelo ebusweni by ospeyita ngalo, yaye lo msebenzi ubandakanya nentabalala yezinto eziphathekayo.
