Te rerekētanga i waenga i te PVC ngohengohe me te PVC mārō

E rua ngā rauemi e taea te wehewehe i te PVC: te PVC mārō me te PVC ngohengohe. Ko te ingoa pūtaiao o te PVC ko te polyvinyl chloride, koinei te wāhanga matua o te kirihou, ā, e whakamahia whānuitia ana hei hanga hua kirihou. He iti te utu, ā, he whānui te whakamahinga. Tata ki te rua hautoru o te mākete te PVC mārō, ko te kotahi hautoru ia o te PVC ngohengohe. Nā, he aha ngā rerekētanga i waenga i te PVC ngohengohe me te PVC mārō?

1. Ngā taumata rerekē o te ngawari me te pakeke

Ko te rerekētanga nui kei roto i ō rātou pakeke rerekē. Kāore he whakangawari o te PVC mārō, he ngāwari te hanga, he ngāwari te pakarukaru, kāore e paitini, kāore hoki e poke, he roa te wā rokiroki, ā, he pai te whanaketanga me te uara tono. Ko te PVC ngohengohe ia, kei roto ngā whakangawari he ngāwari te ngohengohe, engari he ngāwari ki te pakarukaru me te uaua ki te tiaki, nō reira he iti noa te whakamahinga.

1. Tengā whānuitanga tonohe rerekē

Nā tōna ngāwari pai, ka whakamahia te PVC ngohengohe mō te mata o ngā tauera tēpu, ngā papa, ngā tuanui, me te hiako; ko te polyvinyl chloride mārō ka whakamahia nuitia mō ngā paipa PVC mārō, ngā hononga, me ngā kōtaha.

3. Tengā āhuatangahe rerekē

Mai i te tirohanga o ngā āhuatanga, he pai ngā rārangi totoro o te PVC ngohengohe, ka taea te toro atu, ā, he pai te ātete ki ngā pāmahana teitei me te pāmahana iti. Nō reira, ka taea hoki te whakamahi hei hanga tauera tēpu mārama. Ko te pāmahana whakamahinga o te PVC mārō kāore e neke ake i te 40 nekehanga, ā, ki te tino teitei te pāmahana, ka pakaru pea ngā hua PVC mārō.

4. Tengā āhuatangahe rerekē

Ko te mātotoru o te PVC ngohengohe he 1.16-1.35g/cm³, Ko te tere mimiti wai he 0.15~0.75%, ko te pāmahana whakawhiti karāhe he 75~105 ℃, ā, ko te tere whakahekenga whakakoi he 10~50 × 10-³.cm/henimita. Ko te PVC mārō he whānui 40-100mm te nuinga, he maeneene ngā pakitara o roto, he iti te ātete, kāore he unahi, kāore he paitini, kāore he parahanga, ā, he ātete ki te waikura. Kāore te pāmahana whakamahinga e neke ake i te 40 nekehanga, nō reira he paipa wai matao. He ātete pai ki te tawhito, ā, he ātete mura.
