HDPEme te PVC

He tino ngāwari, he ngāwari hoki te whakakorikori i ngā rauemi kirihou. Ka taea te whakakorikori, te pēhi, te whakarewa rānei kia rerekē ngā āhua. He hinu me te hau māori te nuinga o ēnei mea. E rua ngā momo kirihou; he kirihou wera me he kirihou pūwero wera.

Ahakoa kotahi anake te wā ka taea te rewa me te hanga i ngā pūmua thermoset, ā, ka noho totoka ina whakamataohia, ka taea te rewa me te hanga i ngā kirihou thermoplastic i ngā wā maha, nō reira ka taea te hangarua.

E whakamahia ana ngā kirihou wera hei hanga ipu, pounamu, tāke wahie, tēpu me ngā tūru whakapiko, whare tiaki whare, putea kirihou, ārai taura, panera ātete matā, taonga takaro kaukau, whakapaipai whare, kākahu me ngā paipa wai.

He maha ngā momo kirihou wera, ā, ka whakarōpūtia ēnei hei momo kore-āhua, hei momo haurua-kiriata rānei. E rua o ēnei he momo kore-āhua.PVC(polyvinyl chloride) me te HDPE haurua-kiriata (polyethylene kiato teitei). He polymer taonga ēnei e rua.

Ko te Polyvinyl chloride (PVC) he polymer vinyl iti te utu, he pakari hoki e whakamahia ana i roto i ngā kaupapa hanga. Ko te tuatoru o ngā kirihou e whakamahia whānuitia ana i muri i te polyethylene me te polypropylene, ā, e whakamahia whānuitia ana i roto i te hanga paipa. He mama, he kaha hoki, e tino rongonui ana i roto i ngā mahi paipa i runga ake i te whenua me raro i te whenua. He tino pakari, ā, he pai mō te tanu tika me te tāutanga kore-awa.

I tētahi atu ringa, ko te polyethylene kiato teitei (HDPE) he kirihou polyethylene thermoplastic i hangaia mai i te hinu. He kaha ake, he mārō ake, ā, ka taea te tu atu i ngā pāmahana tiketike.
He pai te whakamahi i ngā paipa HDPE i roto i ngā paipa o raro whenua, nā te mea kua kitea ka taea e rātou te whakamakuku me te mimiti i ngā ngaru ru, ā, ka whakaitihia ngā ngaru e pā ana ki te pūnaha. He pai rawa atu hoki te ātete ki te pēhanga hononga, ā, he ātete ki te pakū me te wera.

Ahakoa he pakari, he roa hoki ngā rauemi e rua, he rerekē te kaha me ētahi atu āhuatanga. I tētahi taha, he mea hanga kia tu atu ki ngā taumahatanga rerekē. Kia rite te pēhanga ki te paipa PVC, me 2.5 ngā wā matotoru ake te pakitara o te paipa HDPE i te paipa PVC.

Ahakoa e whakamahia ana ngā rauemi e rua hei hanga ahi,HDPEkua kitea he pai ake, he haumaru ake hoki te whakamahi nā te mea ka taea e ia te tahu i ngā ahi ahi ki te teitei tika. Ki te kore e tīmata i roto i te ipu, ā, ka pakaru, e kore te ipu HDPE e pakaru me te kaha nui pērā i te ipu PVC.

Hei whakarāpopototanga:

1. Ko te Polyvinyl Chloride (PVC) he polymer vinyl iti te utu, he pakari hoki e whakamahia ana i roto i ngā kaupapa hanga, ko te High Density Polyethylene ia (HDPE) he thermoplastic polyethylene i hangaia mai i te hinu.
2. Ko te polyvinyl chloride te tuatoru o ngā kirihou e whakamahia whānuitia ana, ā, ko te polyethylene tētahi o ngā kirihou e whakamahia whānuitia ana.
3. He amorphous te PVC, ko te HDPE he haurua-kirihou.
4. He kaha, he pakari hoki ngā mea e rua, engari he rerekē te kaha me te whakamahinga. He taumaha ake, he kaha ake te PVC, ko te HDPE ia he mārō ake, he ātete ki te pakū, he ātete hoki ki te wera.
5. Kua kitea te kaha o ngā paipa HDPE ki te pehi me te mimiti i ngā ngaru ru, ā, ka whakaitihia ngā ngaru e pā ana ki te pūnaha, engari kāore e taea e te PVC.
6. He pai ake te HDPE mō te tāutanga pēhanga iti, ko te PVC ia he pai ake mō te tanu tika me te tāutanga kore-awa.
