te tukanga hanga o te paipa CPVC#whakaputa paipa#paipa CPVC#paipa PVC

He rite tonu ngā āhuatanga o te tukanga hanga extrusion o te paipa CPVC ki ērā o te paipa noa Paipa PVC , engari ko te rerekētanga ko te whakaritenga kounga o ngā wāhanga taputapu mō te hanga extrusion he teitei ake; ko te whakaritenga whakahaere awhe piki me te heke o te pāmahana tukanga he tino kaha ake.

(1) Te raupapatanga o te tukanga hanga paipa CPVC:

 inehia ngā momo rauemi mata katoa e ai ki te tauira o te rauemi hanga paipa CPVC → Tāpirihia ngā rauemi mata ki roto i te mīhini whakaranu ka whakaranu kia ōrite → Whakaranua kia pai, whakamataohia, ka whakaohokia → kia whakaatuhia ngā rauemi mata kirihou kia rite ki te āhua rewa → Korekore te ngongo hanga pokepokea → Tautuhinga korehau tautuhinga whakamatao diameter → Whakamataohia te paipa me te tāke wai whakamatao → tōia atu → tohu tautuhi → tapahi → Whakawhanui pito paipa → tirohia → Tākai ki roto i te whare putunga

(2) Kōwhiringa taputapu: 

Whakaranua ngā kai ki te mīhini whakaranu tere-teitei, ko te tere hurihuri e hiahiatia ana mai i te 800 ki te 1,000 rpm, ka hipokina ki te taputapu whakaputa hau. Kia ōrite te ranunga o ngā rauemi mata, tomo ki te mīhini whakaranu whakamatao, he iti te tere, ka taea te whakamatao mā te wai whakamatao e rere ana.

Ka taea te whakamahi i te extruder tīwiri kotahi, te extruder tīwiri takirua rānei hei whakakirikiri i ngā rauemi mata. Mena he extruder tīwiri kotahi te mea e whakamahia ana, me āta whakahōhonu haere te hohonutanga o te miro o te hanganga tīwiri.

Mena kei te whakamahi koe i te mīhini whakaputa tīwiri-rua. Me whiriwhiri te momo hurihuri-tahi.

Ina tangohia e te mīhini whakaputa tīwiri kotahi ngā rauemi mata kirihou, me pai ake te taputapu whakaputa hau; he pai ki te whakamatao ki te wai rere, ki te hinu rere rānei. Me whakahaere te piki me te heke o te pāmahana o te tukanga i te ± 5℃. He pai te mīhini whakaputa CPVC. Kāore he pereti porowhita i waenganui i te oko o te mīhini whakaputa me te pokepokea ai; me whakarato he taputapu tiaki taumaha ki te mahi tīwiri.

(3) Te whakahaere i te tukanga whakapūkara me te whakahaere pāmahana:

①Me whakamaroke te kapia CPVC i roto i te oumu 80 mō te 2~4h hei tango i te makuku mai i te rauemi mata

②I muri i te ine, ka konatunatua ngā rauemi mata ki roto i te mīhini whakaranu tere-rahi, ā, ko te pāmahana o te rauemi he tata ki te 115℃.

③Ka whakamataohia te ranunga tere-teitei i roto i te mīhini whakaranu tere-iti kia tae rā anō te pāmahana o te rauemi ki te 40℃.

⑷Ngā kaupapa matua o te tukanga whakahaere:

He uaua ake te hanga i te whakapūtanga o te paipa CPVC ki te whakapūtanga o te paipa PVC. Nā te matotoru me te kore e rere o te wai o te rewa PVC kua whakapūtāhia ki te hauota, he uaua ki te hanga. Ā, he ngāwari te pirau o te rewa i roto i te tukanga whakaputa, nō reira me aro atu ki ēnei raruraru i roto i te hanga whakapūtanga o te kapia polyvinyl chloride kua whakapūtāhia ki te hauota:

①Me whakamaroke te kapia PVC kua whakakīia ki te hauota i mua i te whakamahinga. Me whakamaroke ki roto i te oumu 80℃ mō ngā haora e 2 ~ 4. Mēnā e tika ana, me mata kotahi te mata o ngā rauemi mata, kātahi ka maka ki roto i te hopper o te extruder mō te whakamahinga.

②Me aro nui ki te whiriwhiri i ngā rauemi mata mō te hanga o ngā paipa whakapūtā, ngā mea whakaū me ētahi atu tāpiringa tukatuka, kia kaha ake ai te rere o te wai rewa, kia pai ake ai hoki te pumau o ngā rauemi mata. Whakaranua pai te hanga tuatahi mēnā e tika ana. Whakamātauria te tauira ki roto i te oumu 230℃ mō te 2 hāora. Mēnā kāore he āhua rerekē o te tae me te pirau e kitea ana, he tohu tēnei he tika, he whai take hoki te whiriwhiri rauemi āwhina.

③He paku teitei ake te pāmahana o te tukanga whakaputa o te paipa CPVC i te pāmahana o te tukanga whakaputa o te paipa PVC. Heoi, me mōhio kei neke ake te rerekētanga o te pāmahana whakahaere i te ± 5℃.

④I te tukanga whakaputa paipa CPVC, mēnā he ngoikore te hiko, he ngoikore ngā taputapu, he tohu pirau rewa, he hau paru rānei mai i te waha o te pokepokea ai, me mutu tonu te whāngai ki te rango, whakamahia te kapia PVC hei tango i te rewa CPVC i roto i te pokepokea ai, kātahi ka mutu ki raro hei whakakore i te hapa.

⑤ He kino te hau HCI i tukuna i te wā e pirau ana te CPVC rewa ki te tinana tangata, nō reira kia aro ki te awheawhe whakaputa

⑥Mō te rango whakaputa e whakamahia ana hei hanga kapia CPV, me ārai te rere rewa i roto i te tīwiri me te pokepokea ai ki te waikura hei whakaroa i te roa o te ora o ngā wāhanga taputapu.

⑦Me taupoki te putanga hau kia māmā ake ai te rere o te kohu wai.

⑧Whakamahia te extruder mō te hanga extrusion ngongo CPVC. Me aro ki ngā āhuatanga mahi pēnei i te pūmautanga o te hau me te pāmahana tukatuka o te rango extruder. Mena kāore e taea e ēnei āhuatanga e rua te whakatutuki i ngā whakaritenga whakaputa, ka uaua ake te hanga extrusion o te ngongo CPVC, ka kore rānei e taea.

⑨I te wā e hanga ana i te paipa CPVC, me whai taputapu whakamahana me te whakamatao te tīwiri, ā, me whakarerekē me te whakahaere i te pumau o te pāmahana tukanga kia tika, kia pai ake ai te rere o te rauemi rewa me te whakarite i te kounga hanga o ngā hua.

⑩Ina kore e ōrite te pakitara o roto o te paipa hanga, me tāpiri ngā tāpiri tukatuka acrylate (ngā copolymer rānei) ki te tauira rauemi mata hei whakapai ake i te pāmahana rewa o te CPVC me te PVC; i taua wā, ko te whakahaere pumau o te pāmahana mandrel.
