Ko ngā rauemi o te mowhiti papa e wehea ana ki ngā mowhiti papa kirihou, pērā i te PVC/PTFE/PP, ngā mowhiti papa whakarewa, pērā i te 304/316/410/waro maitai me te mowhiti papa uku. Engari ko ngā rauemi matua e toru, kotahi te momo, pērā i te mea whakarewa me te kirihou, e wehea ana hoki ki ngā rauemi rerekē. He rerekē ngā āhuatanga o ia rauemi.
Mowhiti papa uku
Ngā Painga: He tino ātete ki te waikawa me te wera, me te pāmahana whakamahinga neke atu i te 1300 ℃. Ka taea e ia te tu atu ki te waikura mai i ngā waikawa inorganic, ngā waikawa waro, me ngā whakarewa waro engari ko te waikawa hydrofluoric, me te ātete waikawa o te ≤ 99% me te ātete kawakore o te ≤ 85%. He iti te utu, ā, he maha ngā whakatakotoranga hei whiriwhiri māu, pērā i te φ 16, φ 25, φ 38, φ 50, φ 76, φ 80, φ 100, me ētahi atu, ka taea te whakamahi i roto i ngā āhuatanga pāmahana teitei me te pāmahana iti, ā, he whānui ngā tono.
Mowhiti papa kirihou
Ngā Painga:He mama, kāore e pakarukaru, he ātete ki te wera me te ātete ki ngā matū, he utu whakaputa taurite, he nui te porowhita, he iti te hekenga pēhanga me te teitei o te waeine whakawhiti papatipu, he teitei te pūwāhi waipuke, he rawaka te pa o te hau-wai, he nui te pai o te whakawhiti papatipu. Ko te pāmahana whakamahinga i roto i ngā momo pāpāho ko te 60-280 ℃, he whānui te whakamahinga i roto i ngā ahumahi pēnei i te hinu, te matū, te waikawa kawakore, te hau me te tiaki taiao.
Ngā ngoikoretanga:Kāore e ātete ki ngā pāmahana tiketike, ki ngā waikawa kaha me ngā kawakore, ā, he ngāwari ki te waikura.
Ngā rauemi me ngā āhuatanga rerekē:
PP(polypropylene): ātete ki te wera tae atu ki te 100°C, he iti te utu, engari he ngoikore te ātete ki te waikura.
RPP(Poriporopere Whakakaha): I runga i te PP, kua whakapaitia te kaha ā-pūkaha me te ātete ki te kakahu mā te whakarerekētanga whakakaha, kia pai ake ai mō ngā tono e hiahia ana ki te kaha ā-pūkaha teitei.
PVC(polyvinyl chloride): He pai tōna ātete ki te waikura matū, engari he iti noa iho tōna ātete pāmahana.
CPVC(Polyvinyl Chloride Kua Whakakīia ki te Chloride): He nui ake tōna ātete ki te pāmahana i te PP, e eke ana ki te 110°C, ā, he pai tōna ātete ki te waikura matū.
PVDF(polyvinylidene fluoride): Ka taea e ia te tu atu i ngā pāmahana tae atu ki te 150°C, ā, he tino ātete ki te waikura matū, he mea e tika ana mō te whakamahinga roa i roto i ngā taiao ahumahi uaua.
PTFE(Polytetrafluoroethylene): Ka taea e ia te tu atu i ngā pāmahana tae atu ki te 260°C, ā, koinei tētahi o ngā rauemi tino ātete ki te waikura e mōhiotia ana i tēnei wā, he tino pai mō ngā tukanga matū pāmahana teitei me te tino waikura.
Mowhiti papa whakarewa
Ngā Painga:He pakitara angiangi, he ātete ki te wera me te makariri, he nui te porous, he nui te rere, he iti te whakaiti i te pēhanga, he iti te ātete, he pai te pānga wehewehe, he roa te ora mahi, ā, ka taea te whakamahi katoa i te pūmanawa o ngā taputapu. He pai mō ngā pourewa whakakore hau korehau, ngā pourewa tango hauhā waro, te whakahaere i ngā rauemi e pāwera ana, e ngāwari ana te pirau, e ngāwari ana te whakakīkī, ā, e ngāwari ana ki te whakatakotoranga waro, e whakamahia whānuitia ana i roto i ngā pourewa kua whakakīia i roto i ngā ahumahi pēnei i ngā matū hinu, ngā maniua, ngā matū, me te tiaki taiao.
Ngā ngoikoretanga:Kāore e ātete ki ngā waikawa kaha me ngā kawakore.
Ngā rauemi me ngā āhuatanga rerekē:
Te maitai waro:he iti te utu, engari he ngoikore te ātete ki te waikura, he pai mō ētahi āhuatanga mahi me te ātete waikura ngoikore.
304 kowiri tira:He pai tōna ātete ki te waikura me te wera, ā, ka taea te whakamahi pumau i roto i ngā momo rauemi matū. He rauemi mowhiti pōro whakarewa e whakamahia whānuitia ana.
316L kowiri tira:He pai ake te ātete ki te waikura i te maitai kore waikura 304, inā koa i ngā taiao he kaha te waikura pēnei i ngā katote pūhaumāota. He iti ake te ihirangi waro o te maitai kore waikura 316L, ā, he pai ake te mahi whakarewa, ka taea ai te whakaiti i ngā raruraru waikura intergranular ka puta pea i te wā o te tukanga whakarewa.
