Ko te polyethylene motuhake kua whakakōkōhia ki te kōroine rakau (CPE) i whakawhanakehia e Bontecn Group China Co., Ltd. he whakarerekētanga PVC mahi-teitei i arotauhia mō ngā rauemi hiato kirihou rakau. Ko te nuinga o te wā ka whakarei ake i te pakari, te ātete mura, me te ātete huarere o te kirihou rakau mā te CPE.
Te mahi matua me te mahi:
1. Te Whakapakari me te Whakakaha: Ko te CPE, hei wāhanga rapa kua marara, ka taea te mimiti i te kaha pānga mā te tāpiri i te anga kirihou rakau, te pehi i te horapa o te pakaru, te whakapai ake i te ātete pānga rauemi, ā, he pai mō ngā āhuatanga e pāngia ana e te kaha o waho pērā i ngā kōtaha me ngā panera o te tatau me te matapihi.
2. Ārai mura, ā, ātete huarere: Nā te hanganga kei roto he chlorine ka tineia e ia anō, ka whakaiti i te tāpiri o ngā ārai mura, ā, ka ātete hoki ki te koroheketanga o te UV i ngā taiao o waho, ka whakarite kia pumau tonu ngā hua kirihou rakau mō te wā roa.
3. Mātao me te ārai-waikura: Kia mau tonu te ngāwari i ngā pāmahana iti (i raro i te -30 ℃) me te ātete ki te waikura waikawa me te kawakore, he pai mō ngā taiao haumākū, ngā taiao rerekētanga pāmahana teitei rānei.
Ngā painga o te whakamahinga i roto i te kirihou rakau:
1. Hototahi pai: Ka whakaranua te CPE ki te kirihou rakau polyethylene (PE) me te polyvinyl chloride (PVC) rānei, ka taea te whakapai ake i te rere o te tukatuka me te whakarei ake i te piri o te mata.
2. Te whai huatanga o te utu: Whakakapia ngā kaihoko whakapakeke tuku iho (pērā i ngā elastomer), whakaitihia ngā utu whakaputa, me te whakatutuki i ngā whakaritenga taiao (karekau he konganuku taumaha).
3. Te horopaki noa: Mō ngā panera kirihou rakau, ngā panera whakapaipai whare, me ētahi atu, ko te nui o te tāpiri he 5-10% o te papa hei whakarite i te taurite i waenga i te pakeke me te pakari, me te ārai i te pakarukaru.
Hei whakarāpopototanga, ka taea e te CPE motuhake kirihou rakau te whakatutuki i te mahi hua ritenga, ā, he tāpiri matua hei whakapai ake i te roa me te haumaru o te kirihou rakau.
