Pahuka Viscoelastic (pahuka VE), e mōhiotia ana ko te pahuka mahara, he rauemi polyurethane mahi-teitei e whakamahia whānuitia ana i roto i ngā moenga, ngā urunga, ngā nohoanga motuka, me ngā urunga ahumahi. Ko ōna āhuatanga ahurei o te puhoi-whakahoki me te hanga-tinana i ahu mai i tētahi tukanga tauhohenga polyurethane e āta whakahaeretia ana — ā, kei te ngākau o tēnei tukanga ko tewhakakorikori polyurethane.
Te Mārama ki te VE Foam me tōna Hanganga
Ka hangaia te pahuka VE mā te tauhohengangā polyolmengā isocyanatei te aroaro o te wai, ngā mea pupuhi, ngā mea horoi, me ngāngā whakakorikori polyurethaneKa hangaia e tēnei tauhohenga he hanganga pūtau e whakakotahi ana i te ngāwari me te mimiti pūngao.
Ko te mea nui ki te hanga pahuka VE kounga teitei ko te whakahaere i ngā tauhohenga nui e rua:
- Tauhohenga whakapūkara– Te tauhohenga i waenga i ngā polyol me ngā isocyanate, e hanga ana i te whatunga polymer polyurethane.
- Te tauhohenga pupuhi– Te tauhohenga i waenga i te wai me ngā isocyanate, e tuku ana i te hau CO₂ hei hanga i ngā pūtau pahuka.
Ki te kore e tino whakahaerehia ēnei tauhohenga, ka rerekē pea te mātotoru, te ngawari, te wā whakaora, me te pakari o te pahuka, ka hua ake ai te mahi koretake.
Te Tūranga o ngā Kaiwhakaoho Polyurethane
Ngā whakakorikori polyurethanewhakateretere me te whakataurite i ngā tauhohenga whakapūkara me te pupuhi, e āhei ai ngā kaihanga ki te whakatutuki i te hanganga pūtau me ngā āhuatanga ā-tinana e hiahiatia ana mō te pahuka VE. Ka taea te wehewehe whānui i ēnei whakakorikori ki ngā momo e rua:
- Ngā whakakorikori amine– Ka whakatairanga i te tauhohenga pupuhi, ka pā ki te ngohengohe o te pahuka, te nui o te pūtau tuwhera, me te rere o te hau.
- Ngā whakakorikori whakarewa– Te whakatairanga matua i te tauhohenga whakapūpū, ka pā ki te mārō o te pahuka, te kaha kume, me te pumau.
I roto i te hanga pahuka VE, he huinga hoahoa āta o te amine me te konganukungā whakakorikori polyurethanehei whakatikatika i te kōtaha tauhohenga.
Te Mātāpono o te Mahi Whakakorikori i roto i te Pahuka VE
Ko te mātāpono kei muri i te whakamahi i ngā whakakorikori polyurethane i roto i te hanga pahuka VE e hangai ana kiwhakaterenga whiriwhiriHe rerekē ngā hononga o ngā whakakorikori rerekē mō ngā hononga matū e uru ana ki ngā tauhohenga matua e rua. Mā te whiriwhiri i te ranunga whakakorikori tika me te horopeta, ka taea e ngā kaihanga te:
- Whakahaerehia te wā piki– Te ārai i te hinganga me te whakarite kia rite te whānui o te pahuka.
- Whakahaere i te hanganga pūtau– Te whakatutuki i te hoahoa pūtau-tuwhera e tika ana mō te whakaora puhoi me te manawa ngāwari.
- Tauritehia te ngawari me te tautoko– Te whakatikatika i te auautanga pēhanga pahuka hei whakamarie me te pakari.
- Whakapai ake i te ōritetanga– Te whakaiti i te rerekētanga o ia puranga kia pono ai te kounga.
Hei tauira, i roto i te pahuka mahara, ka āwhina te tauhohenga whakapūmau puhoi ake me te pupuhi taurite ki te waihanga i te pānga puhoi-whakahoki motuhake, me te ārai i te nui o te wera e puta ana i te wā e whakamaroke ana.
Ngā Take e Pā Ana ki te Kōwhiringa Whakakōkī
I te wā e whiriwhiri ana i tētahiwhakakorikori polyurethanemō te pahuka VE, ka whakaarohia e ngā kaihanga:
- Te matotoru o te pahukame ngā whakaritenga mō te mārō.
- Tere tauhohengae hiahiatia ana mō te raina whakaputa (tonu, puranga rānei).
- Ngā paerewa VOC me te kakaramō ngā hua whakamarie.
- Hototahitangame ētahi atu tāpiringa, pērā i ngā ārai mura, ngā tae rānei.
- Ngā ture taiao— te whiriwhiri i ngā kōwhiringa whakakorikori iti-tukunga, pumau hoki.
Ngā Painga o ngā Pūnaha Whakakorikori Arotau i roto i te Pahuka VE
He mea kua arotau paiwhakakorikori polyurethaneka taea e te pūnaha te tuku:
- Te whakamarie me te whakaiti i te pēhanga.
- He roa ake te ora o te pahuka me te manawanui.
- Ka whakaitihia ngā hapa pēnei i te āputaputa, te whakaheke rānei.
- Te whakatutuki i ngā ture taiao me te haumaru.
- Te pai ake o te whakaputa me te whakaiti i te para.
Whakamutunga
Te whakaputanga opahuka viscoelastice hiahia ana kia nui atu i ngā rauemi mata tika anake — me whakahaere tika hoki ngā matū, ā,ngā whakakorikori polyurethanekoinei te kī ki te whakatutuki i tēnei. Mā te mārama ki ngā mātāpono o te mahi whakakorikori me te whiriwhiri i te ranunga tika mō ngā tono pahuka VE, ka taea e ngā kaihanga te whakarite i te kounga pumau, te mahi pai rawa atu, me te painga whakataetae i te mākete.
Ki te mea kei te rapu koengā whakakorikori polyurethane mahi teiteimō te hanga pahuka VE, ka taea e tā mātou tīma hangarau te whakarato i ngā otinga ritenga hei whakatutuki i ō hiahia tukanga me te hua.
