Ko te kaupapa matua o te whakahaere pahuka PVC ka tutuki mā te whakahaere i ngā āhuatanga ā-tinana me te matū o te rewa PVC. Ko ngā mahi motuhake koia ēnei:
1. Whakatairanga i te kirihou me te rewa ōritetanga
Mā te mekameka roa o te pūhui pūhui (ACR) ka tere ake te whakakirikiri o ngā rauemi mā te takai i te mekameka pūhui pūhui PVC, ka whakaitihia te pāmahana tukatuka, ā, ka hanga he hanganga whatunga tiēre. Ehara i te mea ka tere ake te tere rewa i tēnei tukanga, engari ka whakatairangahia hoki te horapa ōrite o ngā tāpiringa me ngā kaihoko pūhui, ka whakaitihia ngā hapa o roto i te rewa.
2. Whakarei ake i te kaha me te ngāwari o te whakarewa
Ko te hanganga whatunga toru-ahu i hangaia e te hononga o ngā mekameka ngota ka whakapai ake i te kaha o te rewa, ka taea ai e ia te kapi i te hau me te ātete i te whakakotahitanga o ngā pūtau i te wā e pupuhi ana. I taua wā anō, ka whakawhiwhia te rewa ki te ngāwari, ka taea ai e ngā pūwero te whānui me te whakaiti ōrite, ka mau tonu te hanganga pūtau kati.
3. Te whakahaere i te taurite viscoelasticity o te rewa
Ka whakatikatika te kaiwhakahaere i te kaha o te waikura o te PVC rewa, ka whakaroa i te wā pahuka, ā, ka whakataurite i te tere pirau o te kaihoko pahuka ki te tere horapa o te hau. Ka taea e tēnei whakahaere te whakaiti i te tere o te pakaru o te mirumiru (e ai ki ngā raraunga whakamātautau, kua heke te tere pakaru mai i te 25% ki te 8%) me te arotau i te ōritetanga o te tohatoha hau i roto i te rewa.
4. Whakapai ake i te hanganga me te pumau o ngā pore
Mā te kaha rewa me te ngāwari kua whakapaitia ka taea te pehi i te pakaru o ngā pūwero tata, ka hanga he hanganga pūtau iti, ōrite hoki. Ka taea e ngā kaiwhakahaere he taumaha ngota teitei ake, pērā i te HL530, te whakaiti ake i te mātotoru o te hua, me te whakahaere anō hoki i te rere o te mekameka ngota hei ārai i te hinganga o ngā pūwero i puta mai i te nui rawa o te whakangā.
5. Whakapai ake i te mata me ngā āhuatanga miihini o te hua
Mā te whakapai ake i te ōritetanga o te rewa ka whakaitihia ngā tohu rere o te mata me ngā hapa whakaheke, ā, ka whakarei ake i te ma o te mata. Mā te pikinga ake o te kaha rewa ka whakarei ake i te ātete pānga me te pumau o ngā āhuatanga o te hua.
Hei whakarāpopototanga, ko tōna kaupapa matua he whakatutuki i te whakahaere tika o te kaha rewa, te viscoelasticity, me te nekehanga huka mā te takai ā-tinana me ngā pānga mahi tahi matū, kia taurite ai te kiato pūtau, te pumau hanganga, me te whai huatanga tukatuka.
