Ko te rauemi o te mono waea o te taura hiko ko te nuinga o tePE (polyethylene), PP (polypropylene) me ABS (acrylonitrile-butadiene-styrene copolymer).
He rerekē ngā āhuatanga o ēnei rauemi, ā rātou whakamahinga me ā rātou āhuatanga.
1. PE (polyethylene) :
(1) Ngā Āhuatanga: He kapia kirihou wera te PE, kāore e paitini, kāore hoki e kino, he iti te ātete ki te pāmahana, he pai ngā āhuatanga whakamarumaru hiko me ētahi atu āhuatanga. He iti hoki te ngaronga me te kaha kawe hiko teitei, nō reira he maha ngā wā e whakamahia ana hei rauemi whakamarumaru mō te waea me te taura ngaohiko teitei. Hei tāpiri, he pai ngā āhuatanga hiko o ngā rauemi PE, ā, he whānuitia te whakamahinga i roto i ngā waea me ngā taura coaxial e hiahia ana ki te kaha waea iti.
(2) Te Whakamahinga: Nā ōna āhuatanga hiko tino pai, he maha ngā wā ka whakamahia te PE ki te whakamahana waea, taura rānei, ki ngā rauemi whakamahana waea raraunga, me ētahi atu. Ka taea hoki e te PE te whakapai ake i tōna ātete mura mā te tāpiri i ngā ātete mura.
2. PP (polypropylene):
(1) Ngā Āhuatanga: Ko ngā āhuatanga o te PP ko te iti o te toronga, te kore e ngāwari, te huruhuru ngawari, te pumau o te tae me te ngāwari o te tuitui. Heoi, he ngoikore te kukume. Ko te awhe pāmahana whakamahinga o te PP he -30℃ ~ 80℃, ā, ka taea te whakapai ake i ōna āhuatanga hiko mā te pahuka.
(2) Te Whakamahinga: He pai te rauemi PP mō ngā momo waea me ngā taura katoa, pērā i te taura hiko me te waea hiko, ā, e tutuki ana i ngā whakaritenga kaha pakaru UL, kāore e taea te hono.
3. ABS (kopolymer acrylonitrile-butadiene-styrene):
(1) Ngā Āhuatanga: He hanganga rauemi pūmua kirihou wera te ABS, he kaha teitei, he pakari pai, he ngāwari hoki te tukatuka. He painga ōna o te acrylonitrile, te butadiene me te styrene e toru ngā monomer, nō reira he ātete ki te waikura matū, he ātete ki te wera, he pakari teitei te mata, ā, he tino ngāwari, he pakari hoki.
(2) Te Whakamahinga: Ko te ABS te mea e whakamahia ana i ngā mahi e hiahia ana kia kaha, kia pakari hoki, pērā i ngā wāhanga waka, ngā whare hiko, me ētahi atu. Mō ngā taura hiko, he mea whakamahi te ABS hei hanga i ngā ārai me ngā whare.
Hei whakarāpopototanga, he rerekē ngā painga me ngā āhuatanga tono o te PE, PP me te ABS i roto i ngā rauemi mono waea o ngā taura hiko. He whānuitia te whakamahinga o te PE i roto i te whakamarumaru waea me te taura nā te mea he pai rawa atu ōna āhuatanga whakamarumaru hiko me te ātete pāmahana iti. He pai te PP mō ngā momo waea me te taura nā te mea he ngawari me te pumau tae; he kaha me te pakari te ABS, e whakamahia ana hei whakamarumaru i ngā wāhanga hiko me ngā raina hiko e hiahia ana ki ēnei āhuatanga.
Me pēhea te whiriwhiri i ngā rauemi PE, PP me ABS e tika ana mō te taura hiko?
I te wā e whiriwhiri ana i ngā rauemi PE, PP me ABS e tino tika ana, me whai whakaaro whānui ki ngā whakaritenga tono o te taura hiko.
1. Rauemi ABS:
(1) Ngā āhuatanga miihini: He kaha, he pakeke hoki te rauemi ABS, ā, ka taea e ia te tu atu i ngā kawenga miihini nui.
(2) Te kanapa o te mata me te mahi tukatuka: He pai te kanapa o te mata me te mahi tukatuka o te rauemi ABS, he mea e tika ana mō te hanga i ngā wāhanga whare hiko, i ngā wāhanga mono rānei he āhua teitei, he pai hoki te tukatuka.
2. Rauemi PP:
(1) Te ātete wera, te pumau matū me te tiaki taiao: E mōhiotia ana te rauemi PP mō tōna ātete wera, te pumau matū me te tiaki taiao.
(2) Te ārai hiko: He tino pai te ārai hiko o te PP, ka taea te whakamahi tonu i te 110℃-120℃, he pai mō te paparanga ārai o roto o te raina hiko, hei rauemi hipoki rānei mō te waea.
(3) Ngā mara tono: He whānuitia te whakamahinga o te PP i roto i ngā taputapu o te whare, ngā taonga tākai, ngā taonga whare, ngā hua ahuwhenua, ngā hua hanga me ētahi atu mara, e tohu ana he whānuitia te whakamahinga me te pono.
3, rauemi PE:
(1) Ātete ki te waikura: He tino pai te ātete o te pepa PE ki te waikura, ā, ka taea te noho pumau i roto i ngā matū pēnei i te waikawa me te kawakore.
(2) Te whakamarumaru me te iti o te mimiti wai: He pai te whakamarumaru o te pepa PE, he iti hoki te mimiti wai, ā, he mea noa te whakamahinga o te pepa PE i roto i ngā mara hiko me te hikohiko.
(3) Ngāwari me te ātete pānga: He pai hoki te ngāwari me te ātete pānga o te pepa PE, he pai mō te tiaki o waho o te raina hiko, hei rauemi hipoki rānei mō te waea hei whakapai ake i tōna pakari me te haumaru.
Mena e hiahia ana te aho hiko kia kaha, kia kanapa hoki te mata, ko te rauemi ABS pea te mea pai rawa atu;
Mena e hiahiatia ana te ātete wera, te pumau matū me te tiaki taiao mō te raina hiko, he pai ake te rauemi PP;
Mena e hiahia ana te raina hiko ki te ātete ki te waikura, ki te whakamarumaru, ā, ki te iti hoki te mimiti wai, he mea pai te rauemi PE.
