Taupānga

Me whakamahi te whakapiri-waahanga e rua i roto i te waa e tika ana i muri i te whakaurunga ki roto RE.Ko te roa o te waa e tika ana ehara i te mea e pa ana ki te ihirangi polymer o te whakapiri, engari ano hoki etahi atu waahanga e tika ana (penei i te resin, antioxygen, plasticizer, solvent, etc.
Ka tata ki te wa e tika ana, he iti noa nga haora, kotahi ra mahi ranei, ka uaua ake te mahi a te whakapiri, ka tere ake te pokey.Ka mutu, ka waiho hei tiēre korekore.100 te whakapiri kounga, Hydroxyl polyurethane (Polyurethane kaute mo te 20%), RE horopeta 4-7.rapa Chloroprene (Rubber account for around 20%), RICHEST RE e 4-7.
