Te rerekētanga i waenga i ngā mīhini PP me ngā mīhini TPR

I roto i tō tātou oranga o ia rā, he taputapu noa ngā wira hurihuri, e whakamahia whānuitia ana i roto i ngā taonga whare, taputapu me ngā taputapu maha. I roto i ēnei, e rua ngā momo wira hurihuri PP me ngā wira hurihuri TPR. Ka whakamāramahia e tēnei tuhinga te rerekētanga i waenga i ngā wira hurihuri PP me ngā wira hurihuri TPR.

I. Ngā Rerekētanga Rauemi
Ko ngā wira PP he mea hanga ki te rauemi polypropylene, ko ngā wira TPR he mea hanga ki te rauemi rapa thermoplastic. He tino rerekē te āhua me ngā āhuatanga o ēnei rauemi e rua.

Polypropylene (PP): He kirihou wera-haurua-kiriata te polypropylene, he ātete nui ki te pānga me te ātete matū, ā, he ngāwari ki te tukatuka. He pakeke me te kaha te nuinga o ngā wira PP, he pai mō ngā wā e hiahia ana ki te kaha kawenga nui.
Rapa kirihou wera (TPR): he momo rapa kirihou wera te rapa, he ngāwari te rapa, he pai te ngāwari me te ātete ki te kakahu, he ngawari ake te kakano o ngā wira TPR, he pai mō ngā wā e hiahia ana kia whakamarietia, kia ata noho hoki.

Tuarua, ngā āhuatanga mahi
Ātete ki te Waro: He pai ake te ātete o ngā wira TPR ki te waro i ērā o ngā wira PP nā te mea he ngawari ake te mata ka pai ake te urutau ki te whenua.
Ātete pānga: Ahakoa he pai ake te ātete pānga o ngā wira PP, i ētahi wā, he pai ake te ātete pānga o ngā wira TPR.
Te Āhuatanga Tukatuka: He māmā te tukatuka i ngā wīra PP, ā, ka taea te werohanga i ngā pāmahana teitei. He uaua ake te tukatuka i ngā wīra TPR, ā, me whakamahi i te werohanga tuarua.
Utu: I te nuinga o te wā, he nui ake te utu o ngā mīhini huri TPR i ngā mīhini huri PP nā te mea he uaua ake te tukanga whakaputa.

Tono
Ngā wira PP: he pai mō ngā wā e hiahia ana kia nui te kaha ki te kawe kawenga me te ātete ki te kakahu, pērā i ngā taputapu taumaha, ngā whata, me ētahi atu.
Ngā wira TPR: e tika ana mō te hiahia mō te ngāwari pai, te ātete pānga pai, te ātete kakahu, pērā i ngā taputapu hauora, ngā taputapu taiwhanga.
