He aha te Polyethylene Whakarerekē?
He aha te Polyethylene Whakarerekē?
Ko te nuinga o nga momo polyethylene kua whakarereketia ko te polyethylene chlorinated, te polyethylene chlorosulfonated, te polyethylene hono-whiti me nga momo rereke kua whakaranuhia.
Polyethylene māotao:
He pūhaumāota matapōkere i whiwhi mā te whakakapi i tētahi wāhanga ngota hauwai i roto i te polyethylene ki te māota. Ko te whakamaaramatanga ka mahia i raro i te tiimata o te marama, te peroxide ranei, a ko te nuinga o te mea ka mahia e te tikanga whakatārewa wai i roto i te umanga. Na te rereketanga o te taumaha me te tohatoha o te ngota, te tohu pekanga, te tohu maaota i muri i te whakamaarama, te tohatoha ngota ngota me te toenga tioata o te polyethylene mata, te polyethylene maata mai i te rapa ki te kirihou pakari ka taea. Ko te whakamahinga matua ko te whakarereke i te polyvinyl chloride hei whakapai ake i te paanga o te polyvinyl chloride. Ka taea hoki te whakamahi i te polyethylene kua whakamaarama hei taonga whakamaarama hiko me te papanga whenua.
Polyethylene Chlorosulfonated:
Ina tauhohe te polyethylene ki te chlorine kei roto sulfur dioxide, ka whakakapia tetahi wahanga o nga ngota hauwai i roto i te ngota ki te chlorine me te iti o nga roopu sulfonyl chloride ki te whiwhi polyethylene chlorosulfonated. Ko te tikanga ahumahi matua ko te tikanga whakatara. Ko te polyethylene Chlorosulfonated he ātete ki te ozone, te waikura matū, te hinu, te wera, te marama, te abrasion me te kaha tensile. He elastomer me nga ahuatanga matawhānui pai ka taea te whakamahi ki te hanga i nga taputapu taputapu e pa ana ki te kai.
XLPE:
Ma te whakamahi i te tikanga iraruke (X-hihi, te hiko hiko, te rauropi ultraviolet, me etahi atu) me te tikanga matū (peroxide, silicone cross-linking ranei) ki te hanga i te polyethylene raina ki roto i te kupenga, te polyethylene hono-whakawhitinga nui ranei. I roto i a raatau, ko te tikanga honohono silicone he mahinga ngawari, he iti nga utu whakahaere, a ka taea te mahi i te hanga me te whakawhiti i roto i nga hikoinga, na reira he pai te pupuhi pupuhi me te werohanga. Ko te parenga o te wera, te awangawanga o te taiao me nga taonga miihini o te polyethylene hono-whakawhitinga kua tino pai ake ki te polyethylene, a he pai mo nga paipa nui, nga taura me nga waea, me nga hua rotomolding.
Te whakakotahitanga o te polyethylene:
I muri i te whakakotahitanga o te polyethylene iti kiato me te polyethylene kiato iti, ka taea te whakamahi ki te tukatuka kiriata me etahi atu hua, a he pai ake te mahi o te hua i te polyethylene iti. Ka taea te whakakotahi i te polyethylene me te ethylene propylene rapa ki te whakaputa i te whānuitanga o nga momo hangareka ngā elastomers
