Kodi mbale yachitsulo yokhala ndi utoto wamitundu yosiyanasiyana imakwaniritsa bwanji anti-corrosion? Chitsulo chachitsulo chokhala ndi utoto, chomwe chimadziwikanso kuti mbale yachitsulo yophimbidwa ndi utoto, ndi chifukwa cha kuphatikiza kwa zokutira, kusanjikiza koyambirira, koyambira, ndi topcoat. Timachitcha kuti "four in one anti-corrosion system of color coated steel plate". Bolodi yathu yokhala ndi utoto imapangidwa ndi mitundu yosiyanasiyana ya zokutira ndikukutidwa m'magulu 5 ndi njira 48, yokhala ndi anti dzimbiri.
Kukana kwa dzimbiri ndi kukana kuzimiririka kwanthawi yayitali.

Kodi timapeza bwanji anti-corrosion ya mbale zokutira zachitsulo? Chitsulo chachitsulo chokhala ndi utoto, chomwe chimadziwikanso kuti mbale yachitsulo yophimbidwa ndi utoto, ndi chifukwa cha kuphatikiza kwa zokutira, kusanjikiza koyambirira, koyambira, ndi topcoat. Timachitcha kuti "four in one anti-corrosion system of color coated steel plate".
Kupaka mbale yachitsulo yamtundu kumagwira ntchito yolimbana ndi dzimbiri. Mwachidule, imakulitsa moyo wautumiki wa mbale yachitsulo mwa kuwononga nthawi zonse zokutira zake. Zoonadi, mtundu, khalidwe, ndi makulidwe a zokutira ndizinthu zazikulu pautali wa nthawi yogwiritsira ntchito zokutira. Mabala athu okhala ndi zitsulo zamitundu yambiri amagwiritsa ntchito malata, aluminiyamu zinki, malata a aluminiyamu magnesiamu ndi mbale zina zachitsulo zochokera kuzitsulo zazikulu zapakhomo, zomwe zimakhala ndi mphamvu zambiri komanso kukana dzimbiri.
Tiyeni tikambiranenso za kusanjikiza chisanadze mankhwala. Ichi ndi gawo lofunika kwambiri la anti-corrosion la mbale zachitsulo zamtundu, zomwe nthawi zambiri zimanyalanyazidwa. Chosanjikiza chisanadze, chomwe chimadziwikanso kuti passivation layer, chimafunika kugwiritsa ntchito njira za passivation monga phosphate kapena chromate kuti zidutse gawo lapansi musanayambe kupaka utoto. Izi sizimangowonjezera kumamatira kwa zokutira, komanso zimathandizira kuti pakhale kukana kwa dzimbiri. Kafukufuku wasonyeza kuti pakuyesa kusalowerera ndale kwa mchere wamchere wa mbale zokutidwa ndi malata, kuchuluka kwa chithandizo chamankhwala osanjikiza bwino kumafikira 60%.
Tiye tikambiranenso zoyambira. Kumbali imodzi, primer imathandizira kukulitsa kumamatira kwa zokutira. Pambuyo filimu ya penti ikutha, sichitha kuchoka ku zokutira, kuteteza kuphulika ndi kutsekedwa kwa zokutira. Kumbali ina, chifukwa cha kukhalapo kwa utoto wotulutsa pang'onopang'ono monga ma chromates mu primer, imatha kutsitsa anode ndikuwongolera kukana kwa dzimbiri kwa zokutira.

Pomaliza, tiyeni tikambirane za topcoat. Kuphatikiza pa kukongola, topcoat makamaka imathandizira kutsekereza kuwala kwa dzuwa ndikuletsa kuwonongeka kwa UV pakuphimba. Pambuyo topcoat kufika makulidwe enaake, akhoza kuchepetsa m'badwo wa micropores, potero kutchinga malowedwe a zowononga TV, kuchepetsa permeability madzi ndi mpweya wa ❖ kuyanika, ndi kuteteza ❖ kuyanika dzimbiri. Kukaniza kwa UV ndi kachulukidwe ka zokutira kosiyanasiyana kumasiyanasiyana, ndipo kwa mtundu womwewo wa zokutira, makulidwe a filimu ya utoto ndi chinthu chofunikira chomwe chimakhudza dzimbiri. Ma board athu okhala ndi utoto amapangidwa posankha mitundu yosiyanasiyana ya zokutira zomwe zidachiritsidwa pakutentha kwambiri, zomwe zimapangitsa kuti tisawononge dzimbiri komanso magwiridwe antchito a nthawi yayitali.
