Ko te kirihou polypropylene roa kua whakapakarihia ki te muka karāhe e pā ana ki tētahi rauemi hiato polypropylene kua whakarerekētia, ko te roa o te muka karāhe he 10-25mm, ka hangaia hei hanganga toru-ahu mā te werohanga me ētahi atu tukanga, e whakarapopototia ana ko te LGFPP. Nā tōna mahi whānui tino pai, kua nui haere te whakamahinga o te polypropylene roa kua whakapakarihia ki te muka karāhe i roto i te ao motuka.
Ngā āhuatanga me ngā painga o te polypropylene kua whakapakarihia ki te muka karāhe roa
- He pai te pumau o ngā āhuatanga
- He ātete tino pai ki te ngenge
- Mahi ngoki iti
- He iti te anisotropy, he iti te whakarerekētanga o te whatu
- He tino pai ngā āhuatanga ā-pūkaha, inā koa te ātete pānga
- He pai te rere, he pai mō te tukatuka hua angiangi
He nui ake te kaha, te pakari, te pakari, te pumau o ngā āhuatanga, me te iti o te piko o te polypropylene whakakaha muka karāhe 10~25mm te roa (LGFPP) ki te whakataurite ki te polypropylene whakakaha muka karāhe poto 4~7mm noa (GFPP). Hei tāpiri, kāore e nui te ngoki o te rauemi polypropylene whakakaha muka karāhe roa ahakoa ka tukuna ki te pāmahana teitei o te 100 ℃, ā, he pai ake te ātete ngoki i te polypropylene whakakaha muka karāhe poto.
I roto i te hua i werohia, ka whakararahia ngā muka karāhe roa ki roto i tētahi hanganga whatunga toru-ahu. Ahakoa kua tahuna te papa polypropylene, ka hanga tonu te whatunga muka karāhe roa i tētahi anga muka karāhe me tētahi kaha, ko te muka karāhe poto ia ka huri hei muka kore-kaha i muri i te tahunga. anga. Ko te take o tēnei āhuatanga ko te ōwehenga roa-ki-te-whānui o te muka whakakaha e whakatau ana i te pānga whakakaha. Ko ngā whakakī me ngā muka karāhe poto he ōwehenga āhua nui ake i te 100 kāore he whakakaha, ko ngā muka karāhe roa he ōwehenga āhua nui ake i te 100 ia he mahi whakakaha.
Ki te whakaritea ki ngā rauemi whakarewa me ngā rauemi hiato whakamahana, he iti te mātotoru o te kirihou muka karāhe roa, ā, ka taea te whakaiti i te taumaha o te wāhanga kotahi mā te 20% ki te 50%. Ka taea e te kirihou muka karāhe roa te whakarato i te ngāwari hoahoa nui ake ki ngā kaihoahoa, pērā i ngā āhua ka taea te hanga me ngā āhua uaua. Mā te maha o ngā wāhanga me ngā wāhanga whakauru e whakamahia ana ka penapena i ngā utu pokepokea ai (i te nuinga o te wā, ko te utu o ngā pokepokea ai werohanga kirihou muka karāhe roa he tata ki te 20% o te utu o ngā pokepokea ai tā whakarewa), ā, ka whakaiti i te whakapaunga pūngao (ko te whakapaunga pūngao whakaputa o ngā kirihou muka karāhe roa he 60% noa iho o te whakapaunga pūngao o ngā hua maitai. %~80%, 35%~50% o ngā hua konumohe), ka whakangawari i te tukanga huihuinga.
Te Whakamahinga o te Polypropylene Whakakaha Muka Karāhe Roa i roto i ngā Wāhanga Motuka
Ka whakamahia te polypropylene kua whakapakarihia ki te muka roa i roto i te anga tinana o te papaaho o te motuka, te whāriki pākahiko, te kōwae pito-mua, te pouaka whakahaere, te anga tautoko nohoanga, te whenua tāpiri, te pare paru, te taupoki anga, te ārai haruru, te anga tatau o muri, me ētahi atu.
Kōwae pito-mua: Mō ngā kōwae pito-mua motuka, mā te whakamahi i te rauemi LGFPP (30% te ihirangi LGF), ka taea te whakauru i te neke atu i te 10 ngā wāhanga whakarewa tuku iho pērā i ngā radiator, ngā kaikorero, ngā whakamātao, me ngā whāriki ki roto i te katoa; he ātete ake ki te waikura i ngā wāhanga whakarewa. He iti te mātotoru, he 30% te whakaiti i te taumaha, ā, he nui ake te herekoretanga hoahoa. Ka taea te hangarua tika me te kore e whakarōpūtia, e tukatukahia rānei; ka whakaitihia ngā utu hanga, ā, he mārama ngā painga ki te whakaiti i te utu.
Angaanga tinana o te papa taputapu: Mō ngā rauemi angaanga papa taputapu ngohengohe, he kaha ake te rauemi LGFPP, he piko ake, he pai ake te rere i ngā rauemi PP kua whakakīia. I raro i te kaha kotahi, ka taea te whakaiti i te matotoru o te hoahoa papa taputapu hei whakaiti i te taumaha, ko te pānga whakaheke taumaha whānui he tata ki te 20%. I taua wā anō, ka taea te whakawhanake i te whāriki papa taputapu maha-wāhanga tuku iho hei kōwae kotahi. Hei tāpiri, ko te kōwhiringa rauemi o te tinana paipa whakarewa o mua me te anga waenga o te papaaho he rite tonu te rauemi ki te anga matua o te papaaho, ka taea ai te whakapai ake i te pānga whakaheke taumaha.
Tua o te nohoanga: Ka taea te whakakapi i te anga maitai tuku iho kia whakaitihia te taumaha o te 20%, ā, he tino pai te herekoretanga hoahoa me te mahi miihini, me ngā āhuatanga pēnei i te whānui o te wāhi nohoanga.
Te hiranga o te whakamahinga o te polypropylene kua whakapakarihia ki te muka karāhe roa i roto i te mara motuka
Mō te whakakapinga rauemi, ka taea e ngā hua polypropylene kua whakapakarihia ki te muka karāhe roa te whakaiti i te taumaha me te utu i te wā kotahi. I mua, i whakakapia ngā rauemi whakarewa e ngā rauemi kua whakapakarihia ki te muka karāhe poto. I ngā tau tata nei, me te tono me te whanaketanga o ngā rauemi māmā, kua piki haere te whakakapinga o ngā kirihou kua whakapakarihia ki te muka karāhe poto e ngā rauemi polypropylene kua whakapakarihia ki te muka karāhe roa i roto i te maha o ngā wāhanga motuka, ā, kei te whakatairangahia tonutia tēnei. Ko te rangahau me te tono o ngā rauemi LGFPP i roto i ngā motuka.
