Ko te polyethylene whai kōrotini teitei (HCPE) ka whakarerekētia i roto i ngā piripiri mā te āhua polarity, te pumau, me te mahi e tukuna ana e tōna hanganga ngota. Ko te tikanga me te whakamahinga motuhake koia ēnei:
1, Mahi matua kua whakarerekētia
1. Whakapai ake i te mahi piri
Whakapai ake i te piri: Kei roto i te mekameka ngota HCPE o Bontecn Group Haina he maha o ngā ngota chlorine (te ihirangi chlorine>61%), e hanga ana i tētahi hanganga porowhita kaha, e whakapai ake ana i te kaha o te makuku me te kaha o te here matū o te piripiri ki ngā rauemi pēnei i te PVC, te konganuku, me te rapa.
Arotau i te ngāwari: Ka whakakīia, ka tohatoha matapōkeretia ngā mekameka ngota ngota, ka karo i te kukū o te ahotea, ka whakawhiwhi i te kiriata piri ki te ātete pānga pai me te ngāwari, me te urutau ki ngā taiao hononga hihiri.
2. Whakapakari i ngā āhuatanga mahi
Ātete ki te waikura me te ātete mura: Ko te nui o te hauwai (>65) ka hanga he ārai matū hei ātete i te waikura mai i te waikawa, te kawakore, me te hinu, ā, ka tineia e ia anō ina mura mā te tikanga hopu i ngā rauropi kore hauwai (te taupū hāora mutunga ≥ 60%).
Ātete ki te kakahu me te ātete ki te huarere: Ko te hanganga kore-hononga takirua ka aukati i te pirau waikura, ka whakaroa i te roa o te ora o te paparanga piri i roto i ngā taiao makuku, wera, me te ultraviolet.
| Momo piripiri | Tauira HCPE | Pānga whakarerekētanga |
| Piripiri motuhake PVC | HCPE-H (Teitei te matotoru) | Te whakakapi i te kapia vinyl chloride hei whakatutuki i te hononga kaha o ngā paipa/pepa PVC |
| Piripiri whakarewa rapa | HCPE-L/M (Matotoru Iti/Waenga) | Rapa chloroprene/rapa nitrile kua whakapakeketia hei whakarei ake i te ātete wera (≥ 130 ℃) me te piri o te mata |
| Paparanga piri mō te paninga ārai-waikura | HCPE-M (Matotoru Waenga) | Whakapai ake i te piri i waenga i ngā paninga, ā, ka whakapai ake i te roa o te ārai-waikura. |
3. Tikanga whakarerekētanga
1. Tikanga whakarei ake i te pōraruraru
Mā te whakaurunga o ngā ngota chlorine ka whakanui ake i te polaritanga ngota, ka whakatairanga i te hanganga o ngā kaha van der Waals me ngā here hauwai i waenga i te piripiri me te mata piri, ā, ka whakapai ake i te mākū.
2. Te whakatikatika hototahi
Whakaranua ki ngā mea whakakoi kirihou (pērā i te paraffin whai kōro), te kapia kiriaku, me ētahi atu hei whakapai ake i ngā āhuatanga rheological me te whakaiti i te ahotea o roto.
4. Ngā wāhi rokiroki
Ngā tikanga rokiroki: Kua hiritia, ā, kua rongoatia ki te pōuri (te pāmahana <30 ℃) hei ārai i te mimiti o te makuku me te hekenga o te mahi, ā, e 24 marama te roa o te oranga.
