1. Yazi kahle amapharamitha ayisisekelo
Amapharamitha obuchwepheshe bomkhiqizo angabonisa isimo esiphelele somkhiqizo. Uma uqonda imikhiqizo yopende elwa nokugqwala kwe-epoxy, amapharamitha obuchwepheshe abe yingxenye ebaluleke kakhulu yokuthenga. Ngokombono wamapharamitha obuchwepheshe ayisisekelo, umbala, ubuncane, okuqukethwe okuqinile, ukuguquguquka, amandla omthelela kanye nezinye izingxenye zefilimu yopende sezibe yingxenye edingekayo. Kuphela ngemva kokuba izingxenye eziningi seziqondiwe kahle, Uzokwazi ukuqonda kangcono ikhwalithi yomkhiqizo.
2. Yazi ukuthi umkhiqizo uyakwazi ukuzivumelanisa nezimo kanjani
Kuphela ngokuqonda ngokucophelela ukuzivumelanisa nomkhiqizo ngesikhathi sokusetshenziswa lapho singazi khona ukuthi yimiphi imikhiqizo engasetshenziswa ngempela ekukhiqizeni. Ngokombono wokuzivumelanisa nomkhiqizo, ukumelana namanzi kanye nokumelana ne-alkali kufanele kucatshangelwe kangcono. Ngemva kokuba ulwazi oluhambisanayo selugcwalisiwe, umphumela wokuzivumelanisa nomkhiqizo uzoba ngcono.
Ngakho-ke, enkambisweni yokuthenga upende we-epoxy ovimbela ukubola, izingxenye eziningi zemingcele yobuchwepheshe kufanele zinakwe. Kuphela ngemva kokuhlaziywa okungcono kwengxenye ngayinye yemingcele yobuchwepheshe, ikhwalithi yomkhiqizo iyonke ingawina ukuvunyelwa kwabantu. Ngithemba ukuthi bonke abangani bangakuhlaziya ngokucophelela ukuze umphumela wangempela wokuthenga kokugcina ube ngcono.
