PVC putorino (kua wehea ki te paipa PVC-U, te paipa PVC-UH me te paipa PVC-O) he mea hanga ki te kapia PVC, te whakau me te hinu whakahinuhinu, kātahi ka peia mā te pēhi wera. Koinei te paipa kirihou tuatahi kia whakawhanakehia, kia whakamahia hoki.
1, Hanganga mowhiti rapa hiri anga maitai whakauru Kua whakauruhia te mowhiti rapa hiri anga maitai me te mura ki roto i te hanga. Kāore te mowhiti rapa hiri anga maitai kua oti te hanga e piko, e whakapēpē, e nekehia rānei i te wā tāutanga. He nui te āheinga whakawhānui o te pūwero, ā, e kore e ngāwari te hutia ki waho kia turuturu, ka whakanui ake i te piri o te hononga, ka whakapai ake hoki i te kounga tāutanga.
2. Teitei o te akuaku. E ai ki ngā paerewa o te ao, he pūnaha tine waro tōna, kāore he tote mata me ngā konganuku taumaha. He matomato, kāore he paitini, he kaha te ātete ki te waikura, he maeneene te pakitara o roto, ā, kāore e mimiti i ngā poke, e whakatupu ai hoki i ngā rimurimu me ngā moroiti. Ehara i te mea ka whakarite noa i te haumaru o te wai inu i roto i te huarahi kawe, engari ka whakarite hoki i te haumaru o te taiao oneone.
3, Roa te ora mahi He hanganga paipa totoka te paipa, he pumau te kounga, he ātete pai ki te waikura. Kāore e pāngia e ngā taunekeneke koiora, ā-tinana me te matū. Kāore e hiahiatia he maimoatanga ārai-waikura mō te whakatakotoranga paipa. E 50 tau te roa o te ora kounga o te whakarōpūtanga rauemi whakauru, ā, ka taea te manatoko ko te 100-150 tau te roa o te ora mahi tuturu e tumanakohia ana.
4, Paerewa kitea teitei Ko te whakamātautau waipū o te paipa pvc-uh ka mahia i runga i te ahotea mowhiti o te 42 MPa, he teitei ake i te paipa PVC-U o te 38 MPa. Ko ia paipa e puta ana i te wheketere ka oti ipurangi 2 ngā wā o te pēhanga ingoa o te whakamātautau waipēhi, teitei ake i te paipa kore-whakarewa o te whare 1.5 ngā wā o te pēhanga ingoa o ngā whakaritenga whakamātautau waipēhi.
5, He iti te utu hanga. He tino nui te diameter o ngā paipa, he kirihou katoa, he ngāwari ki te tāuta, he māmā hoki, he tere hoki. I te wa ano, kāore e pāngia e te pāmahana iti, te puehu, te ua me te hukarere, ā, he mama te taumaha. Ka taea te whakamahi i te hononga hiko ki te papa hanga, kāore he utu wai me te hiko mō te tāutanga, he iti te utu mahi, he iti te utu mīhini, ka taea te hanga i te rā katoa, ka penapena i te wā hanga.
6, Utu whakahaere iti Ka taea e te pakitara o roto o te paipa te noho maeneene mō te wā roa, te whakapai ake i te tere rere, te whakaiti i te ātete mahi, me te iti o te ngaronga o te upoko mō ia roa, ka taea ai te whakaiti i te upoko o te papu me te penapena i te utu whakahaere. He hononga whakatikatika kua pakeke, he ngawari ki te tiaki me te whakaiti nui i te utu tiaki.
7, Teitei o te mahi ā-ru whenua. He momo kōhao te hononga, he hoahoa ngāwari whānui. Mēnā ka tau te papa, ka nekehia rānei, ehara i te mea ngāwari te pakaru. He pai te toronga, te ngāwari me te ātete ki te pēhanga o te paipa. Mēnā ka huri te whenua, ka taea te huri i te tuaka, kia pai ai te ātete ki te ru whenua.

He kaha te ātete o ngā paipa PVC-U ki te waikura, he ngāwari te piri, he iti te utu, ā, he mārō te kakano. Heoi, nā te mimiti o te monomer PVC-U me ngā tāpiringa, he pai anake mō te pūnaha tuku wai me te pāmahana kawe i raro i te 45 ℃. Ka whakamahia ngā paipa kirihou mō te rerenga wai, te wai para, ngā matū, te whakamahana me te whakamatao wai, te kai, ngā wai tino parakore, ngā paru, ngā hau, te hau kōpeke me ngā pūnaha korehau.
Ko te paipa PVC-O te momo whanaketanga hou o PVC putorinoKa whakaputahia te paipa i hangaia mā te hangarau tukatuka aronga motuhake hei whakaputa i te paipa PVC-U mā te totoro axial me te radial, kia whakaritea ai ngā ngota mekameka roa o te PVC i roto i te paipa ki te ahunga biaxial, ā, ka puta he momo paipa PVC hou he kaha teitei, he pakari teitei, he ātete pānga teitei me te ātete ngenge.
PVC putorino ka taea te penapena ki roto, ki waho rānei i te marae. Me tiaki ngā paipa mai i te rā tika ina penapenahia ki waho, ā, me tautoko tika i te wā e penapena ana kia kore ai e tau te rere, e piko rānei. Āraia te hinga me te pikau i ngā kawenga o waho i te wā e kawe ana.
