I ngā tau tata nei, ko te mama, te iti-waro, me te mahi-teitei kua noho hei kaupapa matua e toru o te umanga hanga. Ahakoa he kaha te rauemi whakarewa tuku iho, he nui te kiato, he nui te whakapaunga pūngao tukatuka, ā, he ngāwari ki te waikura; Ahakoa ka whakaitihia te taumaha e te kirihou whakakaha muka karāhe poto noa, he maha ngā wā ka ngoikore te mahi i raro i te kawenga roa, te pāmahana teitei me te iti, me ngā whakaritenga kaha teitei pakitara angiangi. I roto i tēnei horopaki ka tū te polypropylene whakakaha muka karāhe roa (LGF-PP) me te polyamide whakakaha muka karāhe roa (LGF-PA66) hei tētahi o ngā kāwai tino tere te tipu i roto i te mara kirihou whakarerekē o te ao.

Ngā painga hangarau matua o ngā rauemi whakakaha muka karāhe roa

He rerekē tēnei i ngā kirihou poto kua whakapakarihia ki te muka karāhe (ko te roa o te muka kei waenga i te 0.2 ki te 0.6mm), ko ngā rauemi roa kua whakapakarihia ki te muka karāhe ka mau tonu te roa o te 10-25mm i roto i te hanganga kapia mā roto i ngā tukanga whakakī me te whakaputa motuhake, ā, ka hanga he hanganga whatunga toru-ahu i muri i te whakahāngai werohanga.

E toru ngā whakapainga mahi matua ka puta mai i tēnei hanganga:

1. Ātete pānga tino teitei

Ka taea e te whatunga muka karāhe roa te ārai i te horapa o ngā kapiti, ā, ko te kaha pānga o te koki he 40-80% teitei ake i te muka poto PP/PA. I te pāmahana iti o te -40 ℃, ka pakarukaru ngā rauemi noa, engari ka taea tonu e ngā rauemi muka karāhe roa te pupuri i te neke atu i te 80% o tā rātou mahi pānga i te pāmahana rūma.

2. He ātete ngokingoki pai rawa atu me te pumau o te āhua

I raro i ngā kawenga pumau mō te wā roa (pērā i ngā anga o roto o te motuka me ngā waewae tautoko taputapu kāinga), ka nui te rerekētanga o te ngoki o ngā rauemi muka poto, ko ngā rauemi muka karāhe roa ia ka heke te tere ngoki neke atu i te 50% nā te pānga tautoko o te anga muka. I taua wā, i roto i ngā whakamātautau huringa pāmahana teitei me te iti i waenga i te -40 ℃ me te 120 ℃, ko te rerekētanga o te ngoki o ngā hua muka karāhe roa he tata ki te hautoru noa iho o te rerekētanga o ngā muka poto.

3. He kaha teitei, he mama hoki

Ko te mātotoru he 1/2~1/3 noa iho o ngā koranu konumohe (ko te LGF-PP he tata ki te 1.0~1.2 karamu/cm³, ko te LGF-PA66 he tata ki te 1.3~1.5 karamu/cm³), engari ko te kaha motuhake (kaha/mātotoru) he tata, he nui ake rānei i ētahi koranu konumohe, he mea pai rawa atu mō te "whakakapi maitai ki te kirihou".

Ngā wāhi tono noa me ō rātou whakaritenga motuhake mō ngā rauemi

Ngā Raraunga Auahatanga Mākete

E ai ki ngā tatauranga tuatoru, e matapaetia ana ka eke te rahi o te mākete o te ao mō ngā hiato kirihou whakakaha muka karāhe roa ki te 2.8 piriona tāra US i te tau 2023, ā, e matapaetia ana ka eke ki te 4.5 piriona tāra US i te tau 2030, me te tere tipu ā-tau o te 7.2%. I roto i ēnei, ko te rohe o Āhia me te Moana-nui-a-Kiwa te rohe e tere tipu ana, ā, ko Haina, hei kaihanga me te kaweake nui o ngā kirihou kua whakarerekētia, kei te whakakapi haere i ngā rauemi mata utu nui mai i Ūropi me Amerika.

四, to tatou turanga

Neke atu i te 20 tau te arotahi a tā mātou kamupene ki te rangahau me te hanga i te LGF-PP me te LGF-PA66, me ngā mana pupuri hinengaro motuhake mō te hangarau whakaurunga muka roa tonu. Kua kaweakehia ā mātou hua ki te nuinga ki Ūropi, ki Rūhia, ki te Tonga-mā-rāwhiti o Āhia, ki te Waenganui Rawhiti, ki Amerika ki te Tonga me ētahi atu rohe. Ehara i te mea ko ngā tohu paerewa anake tā mātou e whakarato ana, engari ka whakarite hoki i ngā tātai kia rite ki ngā taiao whakamahinga a ngā kiritaki (te pāmahana teitei me te iti, te haumākū, ngā paru hinu, te pānga o waho), ka āwhina i ngā kiritaki ki te whakaiti i ngā utu rauemi me te whakarite i te mahi.
