Ka taea e te ine matotoru o te polymeter te whakakaha, te whakakore rānei i te tukanga whakaputa katoa o te hanga PET. Mō te hunga kua uru ki te umanga PET, ko te nekehanga mai i ngā tikanga ā-ringa uaua ki ngā hangarau hou e tohu ana i tētahi peke nui ki te whai huatanga, te kounga, me te pumau. Ko teIne Rona Ine Marau Whakatū Ine Mataoka puta hei kaiwhakarerekē kēmu, e tuku ana i ngā māramatanga wā-tūturu kimatotoru o te pūmuae whakamana ana i ngā kaihanga ki te arotau i ia wāhanga o ā rātou mahi.
Te Hiranga o te Ine i te Matatini PET
Tematotoru o te pūmuapērā i te PET ehara i te tau noa iho, e tohu ana i te rere o te pūmua rewa, te pupuri i te āhua o ngā pounamu, te pupuri rānei i te kaha o ngā muka. He tikate ine i te matotoru o te pūmuaMā te whakamahi i te taputapu ine matotoru ā-roto matatau, ka taea e koe te ārai i ngā hapa, te whakaiti i te para, inā koa ka whakauruhia te PET hangarua (rPET).
He aha te Polyethylene Terephthalate?
Ko te Polyethylene terephthalate, PET rānei, he polyester thermoplastic i whānau mai i te polycondensation o te waikawa terephthalic me te ethylene glycol, e rongonui ana mō tōna ranunga āhuatanga tino pai. Ko tōna ārai pakari ki ngā hau me te makuku, me te kaha miihini teitei me te māramatanga whatu, e waiho ana hei rauemi whiriwhiri mō ngā mea katoa mai i ngā pounamu inu ki ngā wāhanga motuka. Ko tete matotoru ā-roto o te PETe pā tika ana ki tōna taumaha ngota, e whakatau ana mēnā he pai mō ngā muka kakahu iti-matotoru (0.4–0.7 dL/g) ngā momo pounamu matotoru-teitei rānei (0.7–0.85 dL/g). I te tipu haere o te roa o te mekameka i te wā hanga, ka pērā anō te tipu haere o tematotoru o te pūmua, te hanga i tōna āheinga tukatuka me te whakahohe i ngā tono kua whakaritea kia tutuki ai ngā hiahia kanorau o te ahumahi, tae atu ki te whakaurunga pikinga ake o ngā rauemi hangarua.
He aha te matotoru o roto o te PET?
Tete matotoru ā-roto o te PETHe inenga nui tēnei e wehewehe ana i te takoha a te pūmua ki te whanonga rere, e whakaaturia ana i roto i ngā terita ia karamu (dL/g). E whakaata ana i te rōrahi waiora o ngā mekameka PET i roto i te otinga waimeha, hei tohu pono mō te taumaha ngota me te kore e pāngia e ngā pānga whakararuraru o te kukū. Hei tauira, ko ngā tohu kakahu kei waenga i te 0.4 ki te 0.7 dL/g, ko ngā kirihou hangarau e hiahia ana ki te 1.0 ki te 2.0 dL/g. Ka ārahi tēnei tawhā i ngā tukatuka ki te matapae i te whanonga rewa, te kaha miihini, me te pai mō ngā tono motuhake. Ka taea e ngā rerekētanga o te tioata, te pirau rānei te whakapē.te matotoru ā-roto o te PET, he mea nui te ine tika hei whakarite i te ōritetanga i roto i ngā awa PET hou me ngā awa PET hangarua, hei tiaki i te kounga hua me te pono o te tukanga.

Te matotoru ā-roto o te PET i runga i tōna whakamahinga
Me pēhea te ine tonu i te matotoru ā-roto o te PET
Te ine i te matotoru ā-roto o te PET i te wā tūturu, mai i te huarahi mahi-nui ki te huarahi tonu, e tuku ana i tētahi matapihi wā tūturu ki te tukanga whakapūhui. Tuku Iho.te matotoru o te otinga waimeha o ngā pūmuaKo te whakamātautau, mā te whakamahi i ngā inenga karāhe, me whakarite ā-ringa te tauira me te nui o ngā rahinga whakarewa, ka whakaroa i te whakaputanga.
I roto i te rainangā mita viscometer polymeter, pērā i te Lonnmeter, ka hurihia tēnei mā te whakauru tika ki roto i ngā tauhohenga, i ngā raina whakaputanga rānei, me te inematotoru o te pūmuamā roto i ngā nekehanga auau oro i roto i te pūoko marau whakarārangi. Ka tātarihia tonutia ngā tauira iti, me te tatau i ngā ōwehenga matotoru whanaunga, ka tāpirihia kite matotoru ā-roto o te PETmā te whakamahi i ngā tauira pēnei i te whārite Solomon-Ciutà. Mā te whakatikatika pāmahana ka tika, ka taea e ngā kaiwhakahaere te whakarerekē tonu i ngā tawhā tauhohenga, ka whakarei ake i te mana whakahaere i te taumaha ngota me te pumau o te tukanga.
Ngā Wero i roto i te Ine i te Matatini PET
Te inematotoru o te pūmuaHe maha ngā wero i roto i te hanga PET e hiahia ana ki ngā otinga matatau. Ka puta te rerekētanga o te PET hangarua (rPET) nā te koretake o te pūtake rauemi, ka hua ake he koretake.matotoru o te pūmuangā pānui ka whakararuraru i te tukatuka. Me whakarewa ngā taumata tioata teitei i ngā pāmahana neke atu i te 100°C, ka tūpono te haehae mekameka me te pirau ka pikote matotoru ā-roto o te PETngā hua. Tuku Ihomatotoru o te otinga whakaranuEhara i te mea he roa noa te wā e pau ana i ngā tikanga engari ka tūpono hoki ngā kaiwhakahaere ki ngā whakarewa morearea pērā i te phenol, te tetrachloroethane rānei, ka tū hei mōrearea haumaru. Hei tāpiri, he uaua tonu te hononga o te matotoru o te otinga ki te matotoru rewa i raro i ngā tikanga tukatuka kutikuti teitei, engari ka taea e te waikura i puta mai i te makuku te whakaiti ake i te matotoru, ka uaua ake te whakahaere kounga. E whakaatu ana ēnei arai i te hiahia mō ngā pūnaha aunoa, ā-roto hei tuku raraunga pono, ā-wā tūturu.
