I te mea kei te piki haere tonu te tono mō te pūngao hou, e matapaetia ana ka uru anō te mākete pūngao kiriata o Haina ki tētahi wā tipu nui i roto i ngā tau torutoru e whai ake nei. Kei te piki haere tonu te rerekētanga o te tuku me te tono a te kiriata polypropylene, te rauemi matua o ngā pūngao kiriata, nā te tere o te pikinga o te tono me te puhoi o te tukunga o te kaha whakaputa. Ka tirohia i roto i te tuhinga o tēnei wiki te rauemi matua o ngā pūngao kiriata - te kiriata polypropylene (kiriata PP).

I te mutunga o te tekau tau atu i 1960, ko te kiriata hiko polypropylene tētahi o ngā kiriata hiko matua e toru nā ōna āhuatanga hiko me te tukatuka ahurei me te utu pai rawa atu, ā, i whakamahia whānuitia i roto i te umanga pūnga hiko. I te tīmatanga o te tekau tau atu i 1980, kua tīmata kē te hanga o ngā pūnga kiriata polypropylene whakarewa i ngā whenua whakawhanake i Ūropi me Amerika, i te wā tonu kei te wāhanga whanaketanga o Haina o ngā pūnga kiriata polypropylene whakarewa. Nā te whakaurunga o te hangarau hanga pūnga kiriata polypropylene whakarewa me ngā taputapu matua anake i whiwhi ai tātou i ngā pūnga kiriata polypropylene whakarewa i te tikanga tūturu.

Kia mōhio tātou ki te whakamahinga o te kiriata polypropylene i roto i ngā pūnga kiriata me ētahi kupu whakataki poto. Nō te akomanga pūnga kiriata waro ngā pūnga kiriata polypropylene, ko tōna reo he kiriata polypropylene, he momo manaaki whakarewa te irahiko, he momo kiriata whakarewa hoki, ko te matua o te pūnga he mea takai ki te kapia epoxy, he mea whakauru rānei ki roto i te kirihou me te pouaka whakarewa. Ko te pūnga polypropylene i hangaia ki te irahiko kiriata whakarewa ka kiia ko te pūnga kiriata polypropylene whakarewa, e mōhiotia whānuitia ana ko te pūnga kiriata. Ko te kiriata polypropylene he kapia thermoplastic i hangaia mā te polymerizing propylene. He matotoru ake, he pakari ake, he kaha ake te kume, ā, ka taea te whakamahi mō ngā kiriata kati kōtuhi, ngā putea amo kawenga, me ētahi atu. Ko te polypropylene he polymer kore-paitini, kore kakara, kore reka, he ma miraka, he tino tioata me te mātotoru o te 0.90-0.91g/cm³ anake. Ko tētahi o ngā momo kirihou māmā rawa atu o ngā kirihou katoa e wātea ana. He tino pumau ki te wai, ko te tere mimiti wai i roto i te wai he 0.01% noa iho, ko te taumaha ngota o te ngota he 80,000-150,000.

Ko te kiriata polypropylene te rauemi matua o ngā pūnga kiriata. Ko te tikanga hanga o te pūnga kiriata e kiia ana ko te kiriata whakarewa, e hangaia ana mā te whakamahana i tētahi paparanga angiangi o te konganuku ki runga i te kiriata kirihou hei hikohiko. Mā tēnei ka taea te whakaiti i te rahinga o te kaha o te wae pūnga, kia māmā ake ai te hanga i ngā pūnga iti, kaha-teitei o te kiriata. Ko te nuinga o te pūnga kiriata ko te kiriata turanga, te pepa whakarewa, te waea, te takai o waho, me ētahi atu. I roto i ēnei, ko te kiriata turanga te rauemi mata matua, ā, ko te rerekētanga o te rauemi ka rerekē te mahi a ngā pūnga kiriata. Ko te kiriata turanga ka wehea whānuitia ki te polypropylene me te polyester. Ko te matotoru o te kiriata turanga, ko te teitei ake o te ngaohiko ka taea e ia te tu atu, ā, ko te iti iho o te ngaohiko ka taea e ia te tu atu. Ko te kiriata turanga te kiriata hiko taumata hiko, nā te mea ko te dielectric o ngā pūnga kiriata te rauemi mata matua nui, e whakatau ana i te mahi a ngā pūnga kiriata, ā, e 60%-70% o te utu rauemi te noho. Mō te āhua o te mākete, ko ngā kaihanga Hapanihi te tino rangatira i roto i ngā rauemi mata mō ngā pūnga kiriata kounga teitei, ko Toray, Mitsubishi me DuPont ngā kaiwhakarato kiriata kounga teitei o te ao.

Ko ngā kiriata polypropylene hiko mō ngā waka hiko hou, te hiko photovoltaic me te hiko hau, he nui te rahi i waenga i te 2 me te 4 microns, ā, kua heke te kaha whakaputa neke atu i te haurua i taua wā anō, ki te whakaritea ki te 6 ki te 8 microns mō ngā taputapu whare noa, ā, ka heke te nui o te whakaputanga katoa me te hurihanga o te tuku me te tono mākete. Ka iti te tuku o te kiriata polypropylene hiko i ngā tau e haere ake nei. I tēnei wā, ko ngā taputapu matua o te kiriata polypropylene hiko o te ao e hangaia ana i Tiamana, i Hapani me ētahi atu whenua, ā, ko te huringa hanga o te kaha hou he 24 ki te 40 marama. Hei tāpiri, he teitei ngā whakaritenga mahi o ngā kiriata motuka hiko hou, ā, he torutoru noa ngā kamupene ka taea te whakaū i te whakaputanga papatipu o ngā kiriata polypropylene hiko hiko hou, nō reira, i te ao whānui, kāore he kaha whakaputa kiriata polypropylene hou i te tau 2022. Kei te whiriwhiria ētahi atu haumitanga ki ngā raina whakaputa. Nō reira, tera pea he āputa kaha nui ake mō te umanga katoa i te tau e tū mai nei.
