He aha te PP, ā, he aha tōna hiranga i roto i te mīhini hanga wera iti?
He rauemi tino whānui te whakamahinga o te PP (Polypropylene), ā, he tūranga matua tōna, inā koa i roto i te ao o ngā mīhini hanga wera iti. Ahakoa he paepae kai, he ipu kai, he taupoki kapu, he takai hauora, he arai roto rānei mō ngā hua hiko, kua noho te rauemi PP hei tetahi o ngā rauemi mata e whakamahia whānuitia ana mō ngā mīhini hanga wera iti nā tōna mahi tino pai me te ngāwari ki te tukatuka. Nō reira, he aha rawa te PP? Ā, he aha te hiranga o tēnei mō ngā mīhini hanga wera iti?
He kirihou thermoplastic te PP i whakapūhuitia mai i ngā monomer propylene, he iti te mātotoru, he kaha teitei, he ātete wera pai, ā, he tino pai te pumau matū. Ki te whakatauritea ki ētahi atu kirihou noa pēnei i te PS me te PET, he tino kaha ake te ātete pāmahana teitei o te PP, ā, ka taea te tu atu i ngā pāmahana neke atu i te 100℃, he tino pai mō te hanga ipu whakamahana kai me ngā ipu kai ngaruiti. Hei tāpiri, he pakari pai te PP, ā, kāore e pakarukaru. Ka taea e ia te pupuri i te kaha hanganga pai ahakoa he matotoru angiangi, he mea nui tēnei mō te whakaiti i ngā utu rauemi me te whakatutuki i te hanga mama.
1. Te Āheitanga Tukatuka Pai rawa atu
He whānui te awhe pāmahana whakahāngai o ngā pepa PP i muri i te whakamahana, he rite te whakangawari me te whakahāngai pumau, ā, kāore e ngāwari te pakaru, te mā rānei i te taumahatanga. Mā tēnei ka māmā ake te whakahaere i te pāmahana me ngā tawhā whakahāngai i te wā whakaputa, ka whakapai ake i te tere tohu hua. I taua wā anō, he ngāwari te whakahaere i te tere whakaheke o te rauemi PP i muri i te whakamatao, ka taea te pupuri i te pumau o te taha, ā, he pai hoki mō te whakaputa papatipu me te paerewa.
2. Ngā Āhuatanga Kore-paitini, Kore-Reka hoki
He painga tō te PP, arā, kāore he paitini, kāore he reka, ā, e tutuki ana i ngā paerewa haumaru mō te whakapā atu ki ngā kai, ka taea te whakatutuki i ngā whakaritenga pakari o ngā whenua maha mō ngā rauemi tākai kai. Mō ngā umanga iti me ngā umanga rahi-waenga, mō ngā kaihanga tīmatanga rānei, ehara i te mea he iti noa te utu haumi e hiahiatia ana mō te hanga hua PP me ngā mīhini hanga wera iti, engari ka taea hoki te whakatutuki i te hiahia whakaputa o ngā momo maha i roto i ngā puranga iti.
3. Ātete Wera
Nā te teitei o te pāmahana rewa o te PP, ka nui ake ngā whakaritenga e whakatakotoria ana mō te ōritetanga me te pumau o te pūnaha whakamahana. Mā te whakahaere pāmahana hē ka arahi pea ki ngā raruraru pēnei i te wera kore taurite o ngā pepa, te totoro koretake, te whakarerekētanga rānei o te hua. Nō reira, me whai pūnaha whakamahana whai hua te mīhini hanga wera iti kounga teitei , he waeine whakahaere pāmahana tika, me te pēhanga hanga pumau kia taea ai e ngā pepa PP te whakaoti i te tukanga hanga i te āhua tino pai.
4. Te pakari
He āhuatanga whakaora ngāwari te rauemi PP i te wā e totoro ana, e whakatairanga ana hoki i ngā whakaritenga teitei ake mō te hanganga whakahāngai o ngā taputapu me te hoahoa whakahāngai, ā, ka taea te karo i ngā raruraru pēnei i te matotoru koretake o te pakitara, te whakarerekētanga taha rānei o ngā hua. Mō ngā umanga e tumanako ana ki te whakaputa hua PP mārama, mārama rānei, he mea tino nui te pumau me te tika o ngā taputapu.
5. Utu iti
Tuatahi, he pumau te utu o ngā rauemi mata PP, ā, kua pakari te mekameka tuku, he pai mō te hanga nui mō te wā roa. Tuarua, he iti te matotoru o te rauemi PP, he iti ake te rauemi e hiahiatia ana i raro i te āhua o te rahinga kotahi, ā, ka āwhina tēnei ki te whakaiti i te utu o ia hua. Hei tāpiri, he mama te taumaha o ngā hua PP, he iti hoki te utu kawe, e āhei ai ngā umanga ki te whai painga utu pai ake i roto i te whakataetae mākete.
6. Ngā Taonga Tiaki Taiao
He kirihou hangarua te PP, ā, ka taea te whakamahi anō i raro i te whakaritenga o te pūnaha hangarua. Nā te aro nui o te ao ki te tiaki taiao me te whanaketanga tauwhiro, kua tīmata te maha o ngā umanga ki te whiriwhiri i ngā rauemi hangarua mō te hanga. I te tukatuka PP, ka taea hoki e ngā Mīhini Hanga Mahana PP te tāpiri i tētahi wāhanga o ngā rauemi hangarua e hiahiatia ana, ā, ka whakaitihia ngā utu rauemi mata me te whakaiti i te para rauemi i runga i te kaupapa o te whakarite i te mahi pai o te hua.
I roto i te tukanga whakaputa tuturu, me arotahi te whakataurite i te rauemi PP me ngā mīhini hanga wera iti ki ngā āhuatanga e whai ake nei:
1. Me rite te matotoru o te pepa ki te kaha o te taputapu ki te hanga; ka uaua ake te whakamahana mēnā he pepa matotoru rawa, engari ka pāngia te kaha o te hua e te pepa angiangi rawa;
2. Ko te pāmahana whakamahana ka whakahaeretia i roto i te awhe e tika ana mō te whakangawari PP, ā, me whakarite kia rite te whakamahana o ngā mata o runga me raro o te pepa;
3. Me whakarite kia tika te wā hanga me te wā whakamatao kia kore ai e rerekē te āhua o te hua, e uaua rānei te tango;
4. He pānga tika te āhua o te mata o te pokepokea ai ki te kounga o te āhua o ngā hua kua oti, he mea tino nui tēnei ina koa i te hanga hua mārama.
Ngā taputapu hanga wera iti Kei te whanake haere ki te aunoatanga, te whai huatanga o te pūngao me te tino tika. Mō ngā umanga, ko te māramatanga hōhonu ki ngā āhuatanga o te rauemi PP me te whiriwhiri i ngā mīhini hanga wera iti kounga teitei e rite ana ki tēnā he mea nui hei whakatutuki i te whakaputanga pumau me te whakarei ake i te whakataetae hua.
