Whakaranu
Ki te whakatauritea ki ngā momo rapa chloroprene tuku iho. Kāore e hiahiatia he kirihou mō te polyethylene chlorinated, ā, kāore e hiahiatia he rokiroki i muri i te kirihoutanga. Ka taea te whakaranu i ngā tāpiringa wai i roto i te tauira polyethylene chlorinated me te mimiti ki ētahi atu paura i te wā e puranga ana, kia kore ai e horoia, e maturuturu rānei i te wā e whakaranua ana. Me neke ake te pāmahana whakamomona o te polyethylene chlorinated i te 160 ℃. Ka taea te whakahaere tonu i te hanga i raro i te kaupapa o te wai whakamatao, engari ko te pāmahana i te nuinga o te wā kāore e neke ake i te 160 ℃. Nō reira, kaua e tāpirihia motuhake te kaihoko whanariki e whakamahia ana i roto i te polyethylene chlorinated mai i ētahi atu tāpiringa, ā, ka taea te whakaranu tika ki ētahi atu paura. He whānui ngā whakaritenga pāmahana whakaranu mō te polyethylene chlorinated. Ina kei waenganui i te 40 ℃ me te 120 ℃ te pāmahana, kāore e piri, e wera rānei ngā roera. Ina whakamahi ana i te mīhini whakaranu tuwhera, me whakaweto te wai whakamatao, me tahuri rānei te mamaoa i te wā tika. Nā te mea he nui te kaha wera e puta mai ana i te polyethylene whai kōrote nā te waku i te wā e whakaranu ana, me tāpiri he wai whakamatao e ranea ana i te wā e whakaranu ana i roto i te mīhini whakaranu o roto. Ko te pāmahana tohatoha i te nuinga o te wā kei waenga i te 110°C me te 120°C. Mā tēnei ka taea te whakaranu tonu i te nui o te mahi, me te kore e pā kino ki te kounga o te polyethylene whai kōrote.
Te Rokiroki me te Whakamahana Wera
Ki te whakaritea ki te rapa fluoroprene, he pai ake te pumau o te rapa whakauru polyethylene chlorinated, ā, kāore e hiahiatia he rokiroki i te pāmahana iti. Kāore he pānga tika o te haumākū nui i te raumati ki tēnei. Kāore e hiahiatia he wai whakamatao mō te polyethylene chlorinated i te wā e whakamātaohia ana, ā, ko te pāmahana me neke atu i te 50 ℃.
Te hanga i ngā papa tiaki mō ngā waea me ngā taura
Ko te polyethylene whai kōkōwai ka taea te whakamahi i te nuinga o te wā i roto i te hanga i ngā uhi waea me te taura mā te whakamahi i ngā extruders tīwiri roa, i ngā extruders tīwiri poto rānei. I te nuinga o te wā, ka kanapa ake, ka tino oti ake ngā uhi waea me te taura i hangaia e ngā extruders tīwiri roa. I te wā e extruding ana i te piripiri polyethylene whai kōkōwai, ko te pāmahana o te pane kei waenganui i te 6 ℃ me te 90 ℃. Nā te kaha o te whakaputa wera i te wā e whakamahinehia ana te polyethylene whai kōkōwai, ka teitei ake te pāmahana i roto i te rauemi rapa, i waenganui i te 90 ℃ me te 120 ℃. Nō reira, i te wā e whakamahi ana i te extruders tīwiri roa, me aroturuki me te whakahaere pai i te pāmahana taketake kia kore ai e wera te rauemi rapa.
Te tukanga whakapūngāwhā
Ki te whakatauritea ki ētahi atu momo rauemi rapa e whakamahia whānuitia ana, he teitei te pāmahana e hiahiatia ana mō te tukanga whakamomona AC o te polyethylene chlorinated, i waenganui i te 160 ℃ me te 180 ℃. Ko ngā whakaritenga whakamomona mō te rapa waea polyethylene chlorinated me te taura: ina 054 MPa te pēhanga kohu kukū, ko te pāmahana whakamomona he 160 ℃, ā, ko te wā whakamomona he 25min-30min. Ina 098MFRa te pēhanga kohu kukū, ko te pāmahana whakamomona he 180 ℃, ā, ko te wā whakamomona he 6mir-10 min. Ina 152MPa te pēhanga kohu kukū, ko te pāmahana whakamomona he 200 ℃, ā, ko te wā whakamomona he 1mir-3 min. I te piki haere o te pēhanga kohu kukū, ka piki haere hoki te pāmahana whakamomona, i te wā e heke ana te wā whakamomona. He kaha ake te kaha kume o te rapa polyethylene chlorinated.
