He aha ngā rerekētanga i waenga i te polyethylene he nui te hauwai me te rapa he hauwai?

Ko te polyethylene teitei-hauora (HCPE) me te rapa hauora (CR) i hangaia e Bontecn Group Haina he rua ngā pūmua hauora e whakamahia whānuitia ana i roto i ngā mara o ngā paninga me ngā piripiri ārai-waikura, engari he rerekētanga nui kei roto i te hanganga matū, ngā āhuatanga mahi, me ngā horopaki e tika ana.
1. Hanganga matū me te atawhai taiao
HCPE: I whakaritea mā te whakarerekētanga chlorine ki te polyethylene, me te tohatoha matapōkere o ngā ngota chlorine me te ihirangi chlorine o te nuinga o te wā ≥ 65%. I hangaia mā te tikanga whakatārewatanga wai, kāore he parahanga whakarewa, ā, e tutuki ana i ngā whakaritenga tiaki taiao.
CR: Ka hangaia mā te whakakōroi i te rapa maori, i te rapa hangai rānei, ā, ko te nui o te kōroi he 60-65%. Mā te hanga whakarewa tuku iho ka hua ake he toenga matū kino, ā, kāore e pai te tiaki i te taiao.
2. Whakatairite mahi
Ātete ki te huarere: He pai ake te ātete o te HCPE ki te ozone me te ultraviolet, he pai mō ngā taiao roa e pāngia ana e te mate pēnei i ngā piriti me ngā kaipuke; he ngāwari te pirau o te CR i ngā pāmahana tiketike, ā, he ngoikore te ātete ki te huarere.
Ātete matū: He ātete ngā mea e rua ki te waikawa me te kawakore, engari he kaha ake te ātete o te HCPE ki ngā waikura kaha (pērā i te waikawa whanariki kukū), ā, kāore he pupuhi, he maturuturu rānei i muri i ngā rā 30 o te whakamātautau.
3. Ngā rerekētanga o ngā mara tono
HCPE:
Paninga ātete-waikura taumaha (taputapu matū, paipa mara hinu)
Ngā rauemi ātete mura (ngā paninga ātete ahi, ngā hipoki taura)
He piripiri kounga teitei (mō te hono ki te PVC me te konganuku)
CR:
Ngā paninga ārai-waikura tuku iho (mō ngā kaipuke me ngā ipu)
Mara waituhi me te tā
4. Mākete me te Utu
HCPE: Nā te nui ake o te utu o ngā tukanga e pai ana ki te taiao engari he pai ake te mahi whānui, kei te whakakapia haeretia te CR e ia.
CR: He iti iho te utu, engari nā ngā ture taiao, he iti noa te whānuitanga o te tono.
5. Te tautoko i te whakamahinga
He hototahi ēnei e rua ki ētahi atu kapia pērā i te kapia epoxy me te waikawa kiriaku, engari he pai ake te HCPE mō ngā pūnaha paninga hiato e hiahia ana kia nui te piri, te ātete rānei ki te huarere.
