Zotsatira za Curing Agent Ration

Zotsatira za Chiŵerengero cha Wothandizira Kuchiritsa Ndi kukula kwachuma kwachangu, kupanga ndi kugwiritsira ntchito zitsulo zawonjezeka mofulumira, ndipo makampani onse azitsulo awonanso kukula mofulumira. Panthawi imodzimodziyo, chifukwa cha zifukwa zosiyanasiyana za kuwonongeka kwa zida ndi zowonongeka chifukwa cha zitsulo zowonongeka chaka chilichonse, zimabweretsa kuwonongeka kwakukulu kwachuma ndi kuwononga chuma ndi mphamvu. Chifukwa chake, uinjiniya wotsutsana ndi dzimbiri muzogwiritsa ntchito zitsulo wakopa chidwi chochulukirapo. Kuwonongeka kwachitsulo kumawonongeka makamaka ndi zochita za sing'anga yozungulira. Panthawi ya corrosion, mankhwala kapena electrochemical multiphase reactions zimachitika pamwamba pa chitsulo kuti zitsulo zikhale za ionic, zida zamakina zachitsulo monga mphamvu ndi kulimba zimachepetsedwa, ndipo mawonekedwe amkati amawonongeka. Kufupikitsa moyo wautumiki wa zida, komanso kupangitsa kuti zidazo zichotsedwe. Mu engineering yachitsulo yolimbana ndi dzimbiri, pali njira zambiri komanso njira zopewera kuwonongeka kwachitsulo. Pakalipano, kugwiritsa ntchito zokutira zowonongeka ndizofunika kwambiri, zogwira mtima, zotsika mtengo, komanso zogwiritsidwa ntchito kwambiri. Pakati pawo, ntchito yotsutsana ndi dzimbiri ya epoxy primer imakhala yodziwika kwambiri Yogwiritsidwa ntchito pachitetezo cha dzimbiri chachitsulo.

The epoxy primer yolimba kwambiri imagawidwa mu zigawo ziwiri, A ndi B. Chigawo A chimagwiritsa ntchito bisphenol A epoxy resin monga filimu yopangira mafilimu, ndipo chigawo B ndi polyamide kuchiritsa wothandizira. Polyamide kuchiritsa wothandizila ali yogwira magulu amino ndipo akhoza kuwoloka ulalo ndi magulu epoxy mu epoxy utomoni kutentha firiji kupanga khola ndi wandiweyani dongosolo maukonde, kuti ❖ kuyanika kukhala zabwino adhesion ndi odana ndi dzimbiri katundu. Mlingo wongoyerekeza wa polyamide wochiritsa wothandizira amawerengedwa molingana ndi n (gulu la epoxy): n (yogwira haidrojeni) = 1: 1. Pambuyo posakaniza choyambira cholimba kwambiri cha epoxy ndi mankhwala osiyanasiyana ochiritsa, bolodi imapangidwa ndikuyikidwa mu kutentha. ndi bokosi lowongolera chinyezi kuti lichiritsidwe, chinyezi chachibale chimasinthidwa kukhala 50%, ndipo kumamatira kwa zokutira zonse kumayesedwa pambuyo pochiritsidwa kwathunthu. Pamene kuchuluka kwa machiritso kuli kochepa kuposa mtengo wongoganizira, gulu la epoxy mu utomoni wa epoxy silingathe kutenga nawo mbali pazomwe zimagwirizanitsa ndipo silingathe kupanga mawonekedwe osakanikirana, kotero kuti adhesion ndi osauka kwambiri, makamaka kuchuluka kwa machiritso. ndi theka la mtengo wamalingaliro Pa nthawiyo, idawonetsa chodabwitsa chonse. Pamene kuchuluka kwa machiritso ndi 1.0 ~ 1.2 nthawi zamtengo wapatali, zokutira zonse zimasonyeza kumamatira kwabwino. Pamene wothandizira machiritso ndi 1.5 nthawi zamtengo wapatali, zomatira zidzachepa. Pogwiritsira ntchito, poganizira zinthu zosiyanasiyana, mlingo wa mankhwala ochiritsa nthawi zambiri amakhala 1.0 ~ 1.2 nthawi zamtengo wapatali.
