Ko te nuinga o ngā papa kirihou he HDPE te mea hanga i tēnei wā, ā, he rerekē ngā āhuatanga o ngā momo HDPE rerekē. Ko ngā āhuatanga ahurei o te HDPE ko te huinga tika o ngā taurangi matua e whā: te mātotoru, te taumaha ngota, te tohatoha taumaha ngota me ngā tāpiringa. Ka whakamahia ngā whakakorikori rerekē hei whakaputa i ngā pūmua mahi motuhake kua whakaritea. Ka whakakotahihia ēnei taurangi hei whakaputa i ngā taumata HDPE mō ngā kaupapa rerekē, kia tutuki ai he taurite o te mahi.
I roto i te hanga me te tukatuka o ngā papa kirihou, ka pā te kounga o ēnei taurangi matua tetahi ki tetahi. E mōhio ana tātou ko te ethylene te rauemi mata matua mō te polyethylene, ā, he maha ngā wā ka whakamahia ētahi atu comonomers, pērā i te 1-butene, 1-hexene, 1-octene rānei, hei whakapai ake i ngā āhuatanga polymer. Mō te HDPE, ko te ihirangi o ngā monomers i runga ake nei kāore e neke ake i te 1%-2%. Mā te tāpiri o ngā comonomers ka whakaitihia te tioata o te polymer. Ko tēnei huringa ka inehia mā te mātotoru, ā, he hononga rārangi te mātotoru ki te tioata.
Ina hoki, ka rerekē te mahi a ngā papa kirihou i ngā momo matotoru o te HDPE. Ko te matotoru o te polyethylene matotoru-waenga (MDPE) kei waenga i te 0.926 ki te 0.940g/CC. Ko ētahi atu whakarōpūtanga ka whakarōpū i te MDPE hei HDPE, hei LLDPE rānei. Ko ngā homopolymers te mea tino matotoru, te pakari, te pai o te ātete wai, me te teitei o te ira rewa.
I te nuinga o te wā, i roto i te tukanga hanga papa kirihou, ka hiahiatia ētahi tāpiri hei whakarite i te mahi e hiahiatia ana. Ko ngā whakamahinga motuhake me whai whakatakotoranga tāpiri motuhake, pērā i te tāpiri i ngā antioxidants hei ārai i te pirau o te polymer i te wā tukatuka me te ārai i te waikura o te hua kua oti i te wā e whakamahia ana. Ka whakamahia ngā tāpiri antistatic i roto i te maha o ngā momo takai hei whakaiti i te piri o te puehu me te paru ki ngā pounamu, ki ngā takai rānei.
Hei tāpiritanga, kia pai ai te kounga o ngā papa kirihou, me aro nui ki te takai me te penapena rauemi mata. I te nuinga o te wā, i te wā e penapena ana i ngā rauemi HDPE, me matara atu i ngā pūtake ahi, me ārai i te wera, ā, me noho maroke, me noho pai hoki te whare putunga. Kāore e whakaaetia kia whakaranua ngā poke, ā, kāore hoki e whakaaetia kia pāngia e te rā me te ua. Hei tāpiritanga, i te wā e kawe ana, me penapena ki roto i tētahi kāpata, ki tētahi kāpata rānei, he ma, he maroke, he kua hipokina, ā, kaua e whakaaetia kia mau ki ngā mea koi pērā i ngā whao.
