1. Ngā painga matua
Ātete ki te huarere me te ātete ki te waikura: He pumau te hanganga ngota ngota o te HCPE, he tohatoha matapōkere o ngā ngota chlorine, ā, ka taea te ātete ki te waikura mai i te UV, te ozone, te waikawa, te alkali, te tote me ētahi atu matū, e pai ai mō ngā taiao uaua.
Ātete mura: Ka taea te tineia i a ia anō i muri i te 15 hēkona o te tahunga, kia tutuki ai ngā whakaritenga haumaru ahi.
Te pakari i te pāmahana iti: ka mau tonu te ngāwari ahakoa i raro i te 30 ℃, he pai mō te whakamahi i ngā rohe makariri.
He atawhai taiao: kāore he paitini, kāore he kakara, he iti te parahanga i te wā e hangaia ana, kia rite ki ngā paerewa rauemi matomato.
2. Ngā mahi matua
(1) Mara paninga ārai-waikura
Hei rauemi turanga, ka whakamahia hei paninga ārai-waikura kotahi-wāhanga mō ngā kaipuke, ngā piriti, ngā taputapu matū, me ētahi atu. He ātete ki te wai, te hinu, te waikawa, te kawakore, te tote, me te waikura o te hau, he kaha te piri, ā, he ngāwari ki te tiaki (ka taea te whakaranu i ngā paninga hou me ngā paninga tawhito).
(2) Te Whakarerekētanga Piripiri me te Waituhi
Piripiri: Ka taea e te HCPE-H matotoru te whakakapi i te piri vinyl chloride, ā, ka whakamahia hei here i ngā paipa PVC me ngā rauemi whakarewa. I muri i te rewa ki roto i ngā whakarewa pēnei i te toluene, ka hangaia he wairewa piripiri kaha-teitei.
Waituhi: ka whakarei ake i te ātete ki te kakahu, te ātete ki te waikura, me te ātete ki te mura, he pai mō te tānga kounga teitei.
(3) Ētahi atu tono ahumahi
Hei whakarerekē pānga mō te PVC, ka whakarei ake i te pakari o ngā hua kirihou.
Whakamahia mō ngā hipoki taura, ngā hua rapa (pērā i ngā ngongo, ngā rīpene), me te whakarerekētanga rauemi aukume.
3. Te whakarōpūtanga hua me te takai
HCPE-H: Te matotoru teitei, 25kg/pēke, i hangaia mō ngā piripiri PVC.
HCPE-M: Matotoru waenga, e whakamahia ana mō ngā paninga ārai-waikura/ātete ahi.
HCPE-L: He iti te matotoru, he hototahi ki te kapia kiriaku, he pai mō te tiaki i ngā paipa o raro whenua.
