Pepa Polyethylene Kiato Teitei (HDPE/PE300)
Whakaahuatanga:
Rau Polyethylene PE300 - He kirihou hangarau mama, kaha hoki te HDPE, he kaha te pānga. He tino ātete ki ngā matū me te iti o te mimiti makuku, ā, kua whakaaetia e te FDA. Ka taea hoki te hanga me te whakarewa i te HDPE. Rau Polyethylene PE300.
Ngā Āhuatanga Matua:
He mea hanga te polyethylene kiato teitei hei tetahi o ngā kirihou tino maha ngā whakamahinga o te ao, ā, he maha ngā painga o tēnei. Kua hangaia tā mātou HDPE kia roa te ora, kia iti te tiaki, kia haumaru hoki. Kua whakaaetia te rauemi e te FDA mō te whakamahi i roto i te umanga tukatuka kai, ā, he painga anō hoki ko te ātete ki te makuku, te paru, me te haunga.
Haunga ngā painga maha kua whakarārangihia i runga ake nei, he ātete te HDPE ki te waikura, arā, kāore e pakaru, e pirau, e pupuri rānei i ngā huakita kino. Nā tēnei āhuatanga matua, me tōna ātete ki te huarere, he mea tino pai te HDPE mō te whakamahi i ngā wāhi e tūtaki ana ki te wai, ki ngā matū, ki ngā whakarewa, me ētahi atu wai.
E mōhiotia ana hoki te HDPE he nui te ōwehenga kaha ki te mātotoru (mai i te 0.96 ki te 0.98 karamu), engari he ngāwari ki te rewa me te hanga. Ka taea te tapahi, te mīhini, te hanga, me te whakarewa me/ranei te whakapiri mā te mīhini kia tutuki ai ngā whakaritenga e hiahiatia ana mō ngā tono maha.
Hei whakamutunga, pērā i te nuinga o ngā kirihou hangarau, he ngāwari te hangarua o te HDPE, ā, ka taea te whakaiti i te para me te hanga kirihou.
