Kirihou Polypropylene (PP)
* He kirihou wera haurua-kiriata te polypropylene. He ātete nui ki ngā pānga, he kaha ngā āhuatanga miihini, ā, he ātete ki ngā momo whakarewa waro me te waikura waikawa-pūtake.
* He ātete matū tino pai. E wātea ana ngā momo haumaru mō te kai.
* Ngā hua kirihou PP kua whakaritea, ngā wāhanga rānei
Ko te Polypropylene, e whakarāpopototia ana ko PP, he pūmua i hangaia mai i te propylene mā te tauhohenga pūmua. He rauemi mā, he rite ki te ware pi, he mārama, he māmā te āhua. Ko te tātai matū (C3H6)n, te kiato 0.89 ~ 0.91g/cm3, he mura, ko te ira rewa he 164 ~ 170 °C, he whakangawari i te 155 °C pea, ko te awhe pāmahana e whakamahia ana he -30 ~ 140 °C.
He ātete ki te waikura i te waikawa, te kawakore, te tote wai me ngā momo whakarewa rauropi maha i raro i te 80℃, ā, ka taea te pirau i raro i te pāmahana teitei me te waikura. He whānuitia te whakamahinga, tae atu ki te takai kaihoko, ngā wāhanga kirihou mō te umanga motuka me ngā kakahu.
He aha ngā mea ka taea te hanga mai i te kirihou PP?
Ko te polypropylene te rauemi kirihou māmā rawa atu i runga i te mātotoru. Ko tōna āhua he kirikiri kore tae, he mārama hoki, ā, hei kirihou kai-kai, he whānuitia te whakamahinga i roto i ngā takai kai, pērā i ngā pouaka Styrofoam, ngā kapu kirihou PP, me ētahi atu. E rima ngā wāhanga matua o te polypropylene e ai ki ōna whakamahinga matua: te whakahāngai werohanga PP, te tuhi PP, te muka PP, te kiriata PP, me te paipa PP.

Ngā Āhuatanga o te Polypropylene (PP)
Ātete matū: Kāore ngā kakano waimeha me ngā waikawa e tauhohe ki te PP, ā, he ipu pai rawa atu tēnei mō aua wai (hei tauira, ngā kai horoi, ngā hua āwhina tuatahi, me ētahi atu).
Te ngāwari me te pakari: He ngāwari te PP i roto i tētahi whānuitanga o te piko, ā, ka pāngia e te āhua kirihou i te tīmatanga o te tukanga whakarerekētanga, kāore e pakaru, nō reira e kiia ana he rauemi "pakari".
Ātete ki te ngenge: Ka mau tonu te āhua o te PP ahakoa te maha o ngā takahuri me ngā piko. He tino whai hua tēnei āhuatanga mō te hanga i ngā inihi nekeneke.
Ārai Mate: He nui te ātete hiko o te rauemi PP, ā, he rauemi ārai mate hoki.
Te whakawhiti: Ka taea te hanga i roto i ngā tae mārama, engari he maha ngā wā ka hangaia i roto i ngā tae māori koretake me te nui o te whakawhiti. Mena e hiahiatia ana he whakawhiti teitei, me whiriwhiri te kiriaku, te PC rānei.
Me pēhea te hanga rauemi PP?
Pērā i ētahi atu kirihou, ka tīmata te Polypropylene (PP) hei "wāhanga" (rōpū māmā ake) mai i te whakahoro o ngā wahie hauwaiwai, ka honoa ki ētahi atu whakakorikori hei whakaputa kirihou mā te whakapūhui, mā te tauhohenga whakapūhaumāota rānei.

Polypropylene (PP)– Te tukanga hanga:
Ko te paura i whiwhihia ka haria ki ngā silo paura, kātahi ka hurihia hei pire e whakauru ana i te whānuitanga katoa o
ngā tāpiringa kua marara pai.
Te hangarua kirihou Polypropylene (PP) me te tiaki taiao
Ina hangaruatia te polypropylene, ka whakaitihia te whakamahinga o ngā rauemi mutunga kore pēnei i te hinu me te hau propane. Tata ki te 8% o te hinu o te ao (tata ki te 400 miriona tana) e whakamahia ana i roto i ngā tikanga hanga kirihou tuku iho, e 4% o ēnei e whakamahia ana hei "kaimāori" me te 4% anō e whakamahia ana i roto i te hanga. Mena ka hangaia ngā kirihou mai i ngā kirihou hangarua, ka whakaitihia hoki te whakamahinga pūngao mā te 88%. Nō reira, he pai ki te taiao te hangarua i ngā kirihou polypropylene!
