Me pehea te ine a te Vicat i te parenga wera o te pupa me te takirere UPVC?
Me pehea te ine a te Vicat i te parenga wera o te pupa me te takirere UPVC?;
Ko te rohe pāmahana mahi o upvc vaolo, paipa ko 0-70 ℃. Ko te pāmahana noa he pai mo te mahi i nga rauemi UPVC. ki te nui haere te pāmahana mahi, me tino whakaitihia te ōwehenga o te kaha pehanga o roto. Ko te ōwehenga o te ātete pehanga i raro i ngā momo pāmahana ka whakaatuhia ki te ripanga e whai ake nei hei tohutoro.
Ko te hononga i waenga i te pāmahana mahi o te putorino putunga UPVC me te aukati pehanga:
Te pāmahana mahi | 20 | 25 | 30 | 40 | 50 | 60 |
ōwehenga pēhanga | 100 | 95 | 85 | 65 | 35 | 10 |
UPVC putorino parenga wera i roto i te whakamātautau motuhake he tikanga whakamatautau motuhake ko te Vicat whakamarumaru pāmahana whakamātautau. I muri mai ka whakauruhia e matou te kaupapa o tenei whakamatautau me nga tikanga whakamatautau.
01 te kaupapa whakamatautau: Ko te putorino UPVC he ngawari ki te whakarereke i muri i te wera, ki te pāmahana Vicat ki te ine i te parenga wera o te putorino me te takirere
02 Nga taputapu whakamatautau: Vicat miihini whakamatautau
03 whakaahuatanga whakamatautau:
(1) ka whakanohoia te tauira ki roto i te reo wai, i raro i te ahuatanga o te pikinga o te pāmahana ineohe ki te whakatau i te ngira pehanga paerewa (waahanga-waahanga o te 1mm2) i raro i te mahi o te kaha 50 N, ka pehia ki roto i te tauira lmm ka te pāmahana, ara, ko te Vicat Softening Temperature (VST) o te tauira.
(2) Vicat softening pāmahana he ki te arotake i te ātete wera o ngā rauemi, whakaata i te āhuatanga tinana me te hangarau o ngā hua i roto i te tikanga wera o tetahi o nga tohu.
(3) Ko te teitei ake o te whakamahana whakamahana Vicat, ka pai ake te whakapumautanga o te ahua o nga mea ka pa ki te wera, ka iti ake te rerekee o te waiariki, ara, ko te pai ake o te aukati o te wera.
(4) whakaritenga paerewa motu mo PVC-U putorino tuku wai Vicat whakangohengohe pāmahana ≥ 80 ℃, matou Chuanli Plastics Co., Ltd. hanga o te wai supply ahumahi matū vaolo putorino Vicat pāmahana ko te tikanga 82 ~ 83 ℃. Rauemi putorino wairere tikanga paerewa motu Vicat whakangohengohe pāmahana ≥ 79 ℃, matou chuanli Plastics Co., Ltd. hanga o PVC-U putorino wairere Vicat ngohengohe pāmahana ko te tikanga 80 ~ 81 ℃.
