I te whanaketanga tonu o te hangarau hanga kakahu, kua nui haere ngā muka hou kua waiho hei rauemi mata mō ngā kakahu. I tēnei rā, ka whakaatu atu ahau ki a koutou i te hangarau tautuhi o te muka polyester hangarua.
E mārama ana i mua, nā te kore o ngā tikanga tirotiro me te kore e taea e ngā tari whakamātautau te tuku pūrongo kounga, kāore i taea e ngā umanga te whai hua ki ngā kaupapa here ā-motu e tika ana, ā, i taua wā anō ka whakapoauautia te tapanga o ētahi hua polyester.
He aha te muka polyester hangarua (PET)?
Arā, ka hangaruatia ngā rauemi para polyester (PET) me ngā rauemi para kakahu polyester (PET) ka tukatukahia hei muka polyethylene terephthalate.
Ki te kōrero whānui, ko te muka polyester hangarua (e kiia nei i konei ko te polyester hangarua) e pā ana ki te polyester hangarua (pērā i ngā maramara pounamu, te pahuka, te para hiraka, te para penupenu, te para kakahu, me ētahi atu) i hangaia mā roto i ngā tukanga hangarua. Muka Ester.
Te Kaupapa o te Tāutuhi
I runga i te rerekētanga nui i waenga i te tukanga tukatuka o te polyester hangarua me te polyester wahine, e hua ake ai he rerekētanga o ngā āhuatanga, ka tukatukahia te tauira kia rite ki ngā tikanga kua tohua, ā, ka whakamatautauria ki runga i te chromatograph wai mahi teitei. E ai ki te rerekētanga o te horahanga tihi whanaunga o te tauira i raro i ngā wā pupuri rerekē, kia tutuki ai te kaupapa o te tautuhi kounga.
Te taahiraa tautuhi
1. Te Whakapūtanga Mētano
2. Tango Pupuhi
3. Te kimi i te chromatography wai mahi teitei
Ko ngā wai maimoatanga i tukatukahia i roto i te 1 me te 2 i runga ake nei ka tukuna ki te kimi i te chromatography wai mahi teitei.
4. Te tukatuka raraunga me te tautuhi
Ka puta he panoni i roto i te ihirangi me te tohatoha o ngā hononga mekameka heterogeneous macromolecular me ngā oligomers i te wā o te tukanga whakarite i te polyester hangarua, ka taea te whakamahi hei pūtake mō te tautuhi i te polyester hangarua me te polyester tauhou.
Kei te whakaatuhia ngā mōhiohio mō te wāhi motuhake o te tihi me ngā mōhiohio mō ngā tihi āhuatanga i te ripanga i raro nei.

Titiro ki te heke mai
I te pikinga ake o te kai polyester me te mōhiotanga o te tangata ki te tiaki taiao, ka nui haere te aro ki te hangarua o ngā para polyester. Mā te whakamahi i ngā para polyester hei hanga muka polyester hangarua ka taea te whakaiti i ngā utu, te whakaiti i te kai hinu, me te whakapai ake i ngā painga ōhanga, he mea nui tēnei ki te whanaketanga pumau o te umanga muka matū.
I taua wā anō, me te pikinga ake o te nui o te polyester hangarua, kua nui haere te aro o te umanga ki te whakakapinga o te polyester hangarua me te polyester tauhou. E whakaatu ana hoki te ia o te utu o ngā mea e rua i tētahi hononga pai, ā, kei te piki haere te aro ki te kitenga i te rerekētanga i waenga i ngā mea e rua.
