He aha te Polypropylene Huka-tinana?
Whakamāramatanga me te Hanganga
Polypropylene pahuka ā-tinanaHe momo pahuka polypropylene tēnei i hangaia mā te whakawhanui i te polymer me te whakamahi i tētahi kaihoko pahuka. Ka hurihia e tēnei tukanga te whakaritenga ngota o te rauemi, ka hangaia he hanganga pūtau-kati kua whakakiia ki ngā mirumiru hau ririki. Ko te hua he rauemi mama me ngā āhuatanga ahurei. He rerekē ki te polypropylene paerewa, he totoka, he kikī hoki, he maha ngā pūtau iti, kua kati i roto i te polypropylene pahuka-tinana e whakaiti ana i te taumaha me te whakapai ake i te whakamarumaru. Mā te whakamahinga o tētahi kaihoko pupuhi-tinana, pērā i te hauhā waro, ka āwhina i te hanga i ēnei pūtau i te wā e hangaia ana. Mā tēnei hanganga ka hoatu ki te polypropylene pahuka-tinana tōna hangarau pahuka moroiti matatau, e pai ai mō ngā tono maha e hiahia ana ki te kaha me te taumaha iti.
Ko ngā mahi matua mō te whakaputa PP pahuka ko te pahuka tauhohe, te pahuka wairewa, te pahuka tinei pēhanga, me te whakapai ake i te hanga pehanga. Ka whakamahia e ia tikanga he matū, he matū pupuhi ā-tinana rānei hei hanga i te pahuka. Hei tauira, ka whakamahia e te pahuka tinei pēhanga te CO2 hei whakaputa i tētahi hanganga pūtau-kati, ko te hanga pehanga pai ake ka whakamahia te azodicarbonamide hei whakahaere i te kiato me te rahi o te pūtau.
Ngā Āhuatanga Matua o te Pahuka Polypropylene
Ko te pahuka polypropylene e tū motuhake ana mō ōna āhuatanga miihini me te wera. Ko te hanganga pūtau-kati e whakarato ana i te pumau o te āhua me te whakamarumaru wera pai rawa atu. I te pikinga ake o te nui o te matū pupuhi, ka mama ake te pahuka, ka heke iho tōna kawe wera, ko te tikanga ka pupuri pai ake i te wera ki roto, ki waho rānei. Heoi, ka taea e ngā pūtau hau nui ake te whakaiti i te pakeke me te kaha miihini, engari he kaha tonu te ātete pānga o te rauemi. Ka ātete hoki te pahuka polypropylene ki ngā matū me te makuku, ka roa ai i roto i ngā taiao uaua. Nā ēnei āhuatanga ka waiho te polypropylene kua pahukahia hei whiringa matua i roto i ngā polymer kua pahukahia. Ka whakamahia hoki i roto i ngā hua pēnei i te pepa polypropylene pahuka microporous, he mea nui te māmā me te whakamarumaru.
Ngā Painga Matua o ngā Kōtaha PP Huka Nui
Māmā, ngāwari hoki te whakahaere
Ko ngā kōtaha pp pahuka e tūwhera ana mō tō rātou mama. Ko te hanganga pūtau-kati o te polypropylene pahuka-tinana ka whakaiti i te mātotoru me te pupuri tonu i te kaha. Mā tēnei ka māmā ake te whakahaere me te kawe. Ka taea e ngā kaimahi te hiki me te neke i ngā panera nui, i ngā wāhanga rānei me te iti ake o te kaha.
