1. Whakamāramahia te whakaritenga mō te ihirangi chlorine
Te nui o te haumāota 24% -30%: he pai mō te hanga hua rapa (pērā i ngā paparanga waea ārai, ngā potae).
Te nui o te haumāota 35% -38%: He tino hototahi ki te PVC, e whakamahia whānuitia ana mō te whakarerekētanga pānga o ngā hua PVC mārō (pērā i ngā kōtaha tatau me te matapihi, ngā paipa).
Te nui o te haumāota >40%: ka taea te whakamahi hei mea hanga kirihou, hei rauemi ārai-waikura me te ārai-mura.
2. Aromatawaihia te taumaha ngota me te momo rauemi mata
CPE taumaha ngota teitei: He matotoru me te kaha kume teitei, ka whakaiti pea i tōna piri ki te PVC.
CPE taumaha ngota iti: matotoru iti, rere pai, he pai mō ngā horopaki me ngā whakaritenga mahi tukatuka teitei.
Papa polyethylene kiato teitei: He pai ake te ātete ki te wera o tēnei momo CPE, ā, he pai mō ngā taiao tono pāmahana teitei.
3. Whakatauritehia ngā tukanga whakaputa me ngā whakaritenga mahi
Hangarau mirumiru moroiti hauota: Mena e tika ana kia whakapai ake i te whai huatanga me te ōritetanga o te tauhohenga hauota (pēnei i te whakapoto i te huringa whakaputa), ka taea te whakarite i ngā hua CPE e whakamahi ana i te tukanga tauhohenga mirumiru moroiti.
Te whakamahinga pahuka: Ina whakamahia mō te papa pahuka PVC, me whakakotahi te ōwehenga pahuka (2-3 ngā wā), te mātotoru (0.6-0.7 g/cm³), me te pakeke o te mata hei whiriwhiri i ngā tauira CPE e whakarei ake ana i te kaha rewa.
4. Te hototahitanga me te mahi tahi
Hototahi ki te PVC: Ko te CPE me te ihirangi chlorine o te 35% -38% te mea tino hototahi ki te PVC, ka taea te whakapai ake i te ātete pānga me te kore e pā ki te rere o te tukatuka.
Ātete matū me te ātete mura: He pai te CPE me te nui o te hauwai (>50%) mō ngā āhuatanga ārai-waikura me te ātete mura (pērā i ngā paipa matū me ngā rauemi hanga ātete ahi).
5. Te whakahaere kounga me te tirotiro a te kaiwhakarato
Te ōritetanga o ngā matūriki: Me whakarite kia whakahaeretia te rahi o ngā matūriki CPE i waenga i te 0.1-200 μm hei karo i te piri, i te ngoikore rānei o te wairewa nā te iti o ngā matūriki.
Waitohu me te Whakamātautau: Kōwhiria ngā kaiwhakarato e whakarato ana i te tiwhikete kounga katoa (pēnei i ngā pūrongo whakamātautau ihirangi hauwai, ngā whakamātautau pumau wera), me te whakarite kia manatokohia te mahi a ā rātou hua i roto i te tātai whāinga (pēnei i te tere kirihou, te ōritetanga pūtau). Mā te polyethylene hauwai a Bontecn Group Haina koe e whakarato ki te ratonga me te whakapumautanga kounga.
6. Taurite te utu me te mahi
CPE Whānui: He nui te whai huatanga o ngā hua he iti te nui o te hauwai (35% -38%), ā, ka taea te whakatutuki i te nuinga o ngā hiahia whakarerekētanga PVC.
Ngā āhuatanga papai: Ko ngā whakaritenga mahi motuhake (pēnei i te pahuka tino iti te kiato me te ātete ki te pāmahana teitei) me whai tātai ritenga, ka piki ake pea te haumitanga utu.
Whakarāpopototanga: Me whiriwhiri te CPE i runga i ngā whakaritenga tono, me te taurite tika i ngā horopaki mahi mā roto i ngā tawhā pēnei i te nui o te hauwai, te taumaha ngota, te hototahi, me ētahi atu, me te whakakotahi me te whakamana tukanga whakaputa me te aromatawai tohu kaiwhakarato, kia tutuki ai he taurite pai i waenga i te mahi me te utu.
