Polyvinyl chloride kapia S-700
Ko te Polyvinyl Chloride, e kiia ana ko PVC, ko tetahi o nga momo kirihou ahumahi, ko te putanga o naianei he tuarua anake ki te polyethylene.Kua whakamahia whānuitia te Polyvinyl chloride i roto i te ahumahi, te ahuwhenua me te oranga o ia ra.Ko te Polyvinyl chloride he pūhui polymer kua polymerized e vinyl chloride.He werawera.He paura ma, he kowhai marama ranei. Ka whakarewahia i roto i nga ketones, esters, tetrahydrofurans me te waiwaro maota.He pai te aukati matū.He iti te pumau o te waiariki me te atete marama, neke atu i te 100 ℃, te roa ranei o te puaretanga ki te ra ka timata te pirau hauwai hauwai, me whakauru te hanga kirihou ki te whakapumau.He pai te whakamaarama hiko, kaore e wera.
Koeke S-700ka whakamahia te nuinga ki te whakaputa i nga pepa maramara, ka taea te huri ki roto ki nga pepa maro me nga pepa ahua-maroke mo te kete, te papanga papa, te kiriata pakeke mo te ararewa (mo te pepa takai monamona, kiriata takai hikareti ranei), me etahi atu. kiriata āhua-mārō, pepa, pae kōhikohiko ranei mo te kete.Ka taea ranei te werohia ki te hanga hononga, takirere, waahanga hiko, taputapu motuka me nga oko.
