Ngā Pūrongo

He wero te whakamahinga o ngā kirihou hangai i ahu mai i te hinu nā runga i ngā take tino mōhiotia o te parahanga mā. Kua tino nui, kua tere hoki te rapu i ngā rauemi waro whakahou hei huarahi kē atu. Kua whakaarohia whānuitia te waikawa Polylactic (PLA) hei huarahi kē atu pea hei whakakapi i ngā rauemi hinu tuku iho. Hei rauemi whakahou i ahu mai i te koiora me ngā āhuatanga miihini tika, te hototahitanga pai ki te koiora, me te pirau, kua kite te PLA i te tipu tere o te mākete i roto i ngā kirihou hangarau, ngā rauemi hauora, ngā kakahu, me ngā tono takai ahumahi. Heoi, ko tōna ātete wera iti me te iti o te pakari ka tino whakawhāiti i tōna whānuitanga o ngā tono.

I whakahaerehia te ranunga rewa o te waikawa polylactic (PLA) me te elastomer silicone thermoplastic polyurethane (TPSiU) hei whakapakari i te PLA.

I whakaatuhia e ngā hua i whakaranua pai a TPSiU ki roto i te PLA, engari kāore he tauhohenga matū i puta. Kāore he pānga kitea o te tāpiri o TPSiU ki te pāmahana whakawhiti karāhe me te pāmahana rewa o te PLA, engari i whakaitihia paku te tioata o te PLA.

I whakaatuhia e ngā hua o te āhua me te tātaritanga miihini hihiri te ngoikore o te hototahitanga pāmahana i waenga i te PLA me te TPSiU.

I whakaatuhia e ngā rangahau whanonga rheological ko te PLA/TPSiU rewa he wai rūpahu noa iho. I te pikinga ake o te ihirangi o te TPSiU, i whakaatuhia e te matotoru kitea o ngā ranunga PLA/TPSiU te ia o te pikinga tuatahi, kātahi ka heke iho. He pānga nui te tāpiri o te TPSiU ki ngā āhuatanga ā-pūkaha o ngā ranunga PLA/TPSiU. I te 15 wt% te ihirangi o te TPSiU, ka eke te roanga i te whati o te ranunga PLA/TPSiU ki te 22.3% (5.0 ngā wā i te PLA parakore), ā, ka eke te kaha pānga ki te 19.3 kJ/m2 (4.9 ngā wā i te PLA parakore), e whakaatu ana i te pānga whakapakari pai.

Ki te whakaritea ki te TPU, he pai ake te pānga whakapakeke o te TPSiU ki te PLA i te taha kotahi, ā, he pai ake te ātete ki te wera i te taha kē.

Heoi anō,SILIKE SI-TPVHe mea hanga ki te silicone thermoplastic whakamomona hihiri kua patenttia. He nui te āwangawanga mō tōna mata, he maeneene, he pai hoki mō te kiri, he ātete pai ki te kohi paru, he ātete pai ki te rakuraku, kāore he hinu whakangawari me te hinu whakangawari, kāore he toto/piripiri, kāore he haunga.

Waihoki, he pai ake te pānga whakapakeke ki te PLA.

He rauemi ahurei, haumaru hoki tēnei, he pai hoki mō te taiao, ā, he pai te whakakotahitanga o ngā āhuatanga me ngā painga mai i ngā kirihou wera me te rapa silicone honohono-katoa. He pai mō ngā mata mau, ngā kirihou hangarau, ngā rauemi hauora, ngā kakahu, me ngā tono takai ahumahi.
