5 ngā rauemi mata kirihou noa mō te waea me te taura

Ahakoa ngā momo o waeame taurahe rerekē, engari he rite te nuinga o te hanganga o ngā hua, he rite tonu ngā rauemi mata e whakamahia ana, ko ngā rauemi mata noa ko ngā rauemi kawe hiko, ngā rauemi whakamahana, ngā rauemi tiaki, ngā rauemi whakamarumaru, ngā rauemi whakakī, me ētahi atu, me te acTauraE ai ki ō rātou āhuatanga rerekē, ka taea te wehewehe ki ngā wāhanga e rua, arā, ko ngā rauemi mata whakarewa, pērā i te parahi konumohe, te koranu konumohe, me ngā rauemi mata kirihou. Ko ngā momo rauemi mata kirihou e rima e whakamahia whānuitia ana i roto i te PVC, PE, PP, me ētahi atu.waeame taura.

1. PVC, koinei te rauemi mata kirihou e whakamahia whānuitia ana mō te waea me TauraKo te PVC te mea e whakamahia whānuitia ana mō te whakamarumaru waea me te taura, me te rauemi tiaki hoki, nā te mea he maha ngā āhuatanga tiaki pai o te PVC hei tiaki pai i te roto o te waea me te taura, pērā i te kore e ngawari ki te tahu, te ātete ki te koroheketanga, te ātete ki te hinu, te ātete ki te waikura matū, te ātete ki te pānga. Nā ēnei āhuatanga he pai te pānga wehe me te tiaki, nō reira ko te nuinga o ngā rauemi whakamarumaru o te waea me te taura he rauemi PVC.

2. KI RĀ(Polyethylene), ko tōna āhua ā-tinana he ma, he mārama, he rite ki te ware pi, he tino ngāwari, ka taea te totoro ki tētahi roa, he mama ake i te wai, kāore he paitini, engari ki te whakatauritea ki te PVC, he ngāwari te tahu o te polyethylene. Ahakoa ka wehe atu i te ahi, ka noho tonu te āhua mura, he maha ngā momo polyethylene kua whānuitia, tae atu ki te LDPE, MDPE, HDPE, ko te LDPE tētahi o ngā mea tino iti te mātotoru, e mōhiotia ana ko te polyethylene pēhanga-iti, he tino pai te ngāwari. Ko te MDPE he polyethylene mātotoru reo, e mōhiotia ana ko te polyethylene pēhanga-waenga, he rite tonu te mahi me te polyethylene mātotoru teitei. E mōhiotia ana hoki te HDPE ko te polyethylene pēhanga-teitei, he tino pai ake tana mahi whānui, inā koa kua arotauhia te ātete wera me te kaha miihini. He tino pai ngā āhuatanga whakamarumaru hiko o te Polyethylene, ā, he whānuitia te whakamahinga i roto i te whakamarumaru o ngā taura whakawhitiwhiti kōrero.

3. EVA(te kopolymer etilena - winira acetate), he kirihou wera rite ki te rapa, he hononga pai tōna mahi me te ihirangi vinyl acetate (VA), ko te iti o te ihirangi VA he rite ki te polyethylene, ko te teitei ake o te ihirangi he rite ki te rapa ngā āhuatanga, he pai te ngāwari o te EVA me te ātete pāmahana iti, ā, he ātete matū. I te whakaranua ki te LDPE, ka taea te whakapai ake i te raruraru he ngāwari te pakaru o te LDPE, ā, ka taea te whakarite me te whakapakari i te ātete pānga, te ngawari me te pakeke, me te piri i waenga i te kaiarahi me te whakamarumaru.

4. PP(Polypropylene), koinei te mea he iti rawa te ōwehenga i waenga i ngā kirihou e whakamahia whānuitia ana i tēnei wā, he kaha miihini teitei, he ātete pāmahana iti, he ātete koroheketanga tino pai, me te kaha pakaru teitei, me ngā āhuatanga mimiti wai iti, ka taea e te rauemi PP te pai mō te tūranga o ngā rauemi whakamarumaru auau teitei.

5. Polyester, he nui te ātete haehae, te ātete kakahu, te ngāwari me te iti o te hysteresis o tēnei momo rauemi, ko te rohe o runga o te pāmahana e tika ana ka eke ki te 1500 nekehanga Celsius, he nui ake i ērā atu rapa thermoplastic, engari he pai hoki te ātete hinu me ngā āhuatanga ātete whakarewa.
