He rauemi pūmua motuhake te polyethylene chlorinated (CPE) e whakakotahi ana i te kaha kirihou me te ngāwari o te rapa. Ka taea te whakarerekē i te nui o te chlorine (25% -45%). He tino ātete ki te huarere, he ātete mura, he pumau matū hoki, ā, he whānuitia te whakamahinga i roto i ngā mara e whai ake nei:
1. Kaiwhakarerekē ahumahi kirihou
Hei whakarerekētanga mō ngā kapia pērā i te polyvinyl chloride (PVC), ABS, me ngā polyolefins, ka taea e ia te whakarei ake i te pakari, te whakapai ake i te āheinga tā, me te ātete mura o te PVC, ā, e whakamahia ana hoki i roto i te hanga papa kore-mura, hiako hangai, papa, me ētahi atu.
Mā te whakaranu ki te polyurethane ka taea te whakapai ake i te mahi a ngā kirihou pahuka, ngā kiriata, te uhi taura me ētahi atu hua.
2. Ngā rauemi rerekē mō ngā hua rapa
Hei rapa motuhake e pai ana ki te taiao (pērā i te rauemi momo-B polyethylene kua whakakōkōhia ki te hauota), ka whakamahia hei paparanga whakamahana o ngā waea me ngā taura, ngā ngongo rapa, ngā whitiki kawe, ngā potae motuhake, me ētahi atu, hei whakakapi i te rapa tuku iho, ā, he pai ake te ātete ki te makariri, te ātete ki te hinu, me te ātete ki te mura.
Mā te whakaranu ki te rapa ethylene propylene (EPR), te rapa nitrile (NBR), me ētahi atu rauemi ka taea te whakapai ake i te mahi whānui o ngā hua rapa.
3. Ngā rauemi hanga me ngā mahi ārai-wai me te ārai-waikura
Ko te umanga hanga, pērā i ngā kiriuhi ārai wai me ngā rīpene hiri, te mākete kaihoko nui rawa atu, inā koa mō ngā hua nui te hauota (te ihirangi hauota >40%) e tika ana mō ngā āhuatanga hou pērā i te kiriata photovoltaic me ngā ringaringa teihana turanga 5G.
4. Te Ahumahi Hikohiko me te Aunoa
Te hanga i ngā wāhanga anga hiko e ātete ana ki te pakaru o te pewa, me ngā wāhanga kirihou e ātete ana ki te tawhito mō ngā waka.
Ko ngā āhuatanga pēnei i ngā hipoki waea waka e whakawhirinaki ana ki tōna ātete mura me te ātete huarere.
5. Ētahi atu tono
Te whakarerekētanga piri (hei whakapakari i te pakari me te ātete ki te mura), ngā muka, ngā rauemi pahuka, me ētahi atu.
