Kupu Whakataki
I roto i ngā kiriata tiaki waka, he rite tonu te tangi o ngā tapanga rauemi ahakoa he rerekē te arorau tono. E kōrerohia ana te TPU me te PCU hei pūnaha polymer mahi-teitei, engari ko te uara o ia rauemi e whakawhirinaki ana ki te whakamahinga whakamutunga. Ko te TPU, inā koa ko te TPU aliphatic, he whānuitia te tūnga mō te tiaki mata nā te mea e whakakotahi ana i te ngāwari, te ātete UV, te ātete ki te pakū, me te pumau tae. E whakaahua ana a Lubrizol i ngā matū TPU aliphatic he pumau tae, ā, he pai mō te tiaki mata, me te ātete kaha ki te pakū me te rakuraku.
Ko te PCU, i roto i te reo mākete o nāianei, e whakamahia ana hei whakaahua i tētahi whānau kiriata polyurethane e ahu mai ana i te polycarbonate, kaua ki tētahi kāwai tiaki motuhake. E whakaatu ana ngā rangahau mō te polyurethane e ahu mai ana i te wāhanga ngohengohe o te polycarbonate ka taea e ēnei pūnaha te whakarato i ngā āhuatanga miihini kaha me te pumau wai, e whakamārama ana i te take he mea ātaahua te matū polycarbonate i roto i ngā tono polymer uaua. Ko te pātai i roto i te kiriata motuka ehara i te mea ka taea e te PCU te mahi, engari ko te mea pai rawa atu mō ngā whakaritenga whatu, mata, me te pakari o te whakamahinga waka tūturu.
Te Tikanga o te TPU me te PCU i roto i te Hanganga Rauemi
He whānau polyurethane thermoplastic wehewehea te TPU. Ko ōna āhuatanga e whakawhirinaki ana ki te matū o te wāhanga ngohengohe me te wāhanga mārō, ko te tikanga ka taea te whakarite i te TPU mō ngā taurite rerekē o te ngāwari, te mārama, te hoki whakamuri, me te pakari. E whakaahua ana ngā arotake mātauranga i te TPU hei akomanga rauemi he kaha te tukatuka me te taurite āhuatanga o te ngāwari me te pakari, ko Lubrizol ia e whakaatu ana i ngā kōwhiringa whānui o te pakeke me te pai o te tiaki mata.
PCU, ina whakamahia i roto i tengā tae o te motukaKo te mākete, e hono ana ki te matū polyurethane e ahu mai ana i te polycarbonate. Kua pūrongohia te whakaatu a te PU wāhanga ngohengohe polycarbonate i te mahi miihini pai rawa atu me te pumau hydrolytic, ā, kua honoa ngā macrodiol polycarbonate ki te whakapai ake i te whakauru wāhanga me te whanonga kume i roto i ngā pūnaha polyurethane wāhanga. Ko te tikanga ka taea te whakapono hangarau PCU. Ko te take matua ko te whakapono hangarau anake ehara i te mea ko te tūāpapa kiriata pai rawa atu mō te tiaki motuka o waho.
He aha te nuinga o te wā ka pai ake te uru o te TPU ki te kiriata motuka
Ehara i te matū pūmua anake te mea e aromatawaihia ai te kiriata motuka. Me noho mārama, me ātete ki te rakuraku, me ora i te pānga o te hihi UV, ā, me noho pumau tonu i muri i te tāutanga. E whakaatu ana a Lubrizol i te TPU aliphatic hei kōwhiringa kaha mō te tiaki mata nā te mea he ātete ki te hihi UV, he ātete ki te pakū me te rakuraku mō te wā roa, me te pumau o te tae i roto i ngā tono mārama, mārama rānei. Koinei tonu ngā āhuatanga e whai tikanga ana i roto i te kiriata tiaki peita, te kiriata tiaki matapihi, me ētahi atu mata motuka e kitea ana.
He whānui ake te whakamahinga o te TPU i roto i ngā kiriata tiaki, nō reira kua pakari ake te mōhiotanga o te mākete mō te hanganga, te hototahitanga o te paninga, me te pupuri i te āhua mō te wā roa. I roto i te mahi, ko te tikanga he māmā ake te whakanoho i ngā kiriata TPU ina he mea nui te māramatanga, te pakari, me te kounga o te mata kounga teitei i te wā kotahi. Mō te whakamahinga motuka, he painga nui tēnei nā te mea ehara te hua i te pepa polymer anake; he pūnaha paparanga e tika ana kia ātaahua te āhua me te mahi tonu i runga i ngā mata waka tūturu.
Ngā Wāhi e Whai Hua ai te PCU, me te He aha i Kei a Ia Ngā Taurite Tonu
Kāore he painga o te PCU. Ka taea e ngā pūnaha PU e ahu mai ana i te polycarbonate te whakarato i ngā āhuatanga miihini kaha me te pumau wai, e pai ai ki ngā taiao e āwangawanga nui ana mō te ātete ki te makuku me te kaha o te polymer. I ētahi wā, he mea nui tēnei mō ngā tono motuhake, mō ngā kiriata hangarau rānei e arotahi ana ki te hanganga matū.
Ko te painga, kāore te kiriata motuka e arotauhia ana i te taha o te pumau wai anake. Me pupuri hoki te kiriata e anga ana ki te waka i te koretake o te tirohanga, te ātete ki te kakahu o te mata, me te pupuri i te āhua tirohanga ma i raro i te rā me te horoinga auau. He pai ake te hangai o te TPU ki aua whakaritenga. He rerekē, ko ngā pūnaha polyurethane e hangai ana ki te polycaprolactone, he whānau wāhanga ngohengohe anō hoki i roto i tēnei kōrero, e whakanuia ana mō te ngāwari me te pirau koiora, engari he nui ake te hiranga o aua āhuatanga i roto i ngā tono rauemi hauora, rauemi pumau rānei i roto i te tiakitanga o waho o te motuka mō te wā roa. Kua pūrongohia hoki ētahi kiriata polyurethane e hangai ana ki te PCL he ngawari ki te pirau wai, e whakaatu ana ko ngā kaha o tētahi rauemi i roto i tētahi mara kāore e waiho hei whiringa pai rawa atu mō tētahi atu mara.
Whakataurite i runga i te Taupānga
Mai i te tirohanga tono, ko te TPU te whiringa haumaru ake mō te kiriata motuka nā te mea he pai ake te hangai ki te puranga mahi tūturu e hiahiatia ana mō ngā waka. Kei roto i taua puranga te pumau o te UV, te ātete ki te rakuraku, te mārama o te whatu, te ngāwari i te wā tāutanga, me te pupuri i te āhua mō te wā roa. E hokohokohia ana te TPU Aliphatic mō ēnei āhuatanga i roto i ngā whakamahinga tiaki mata, koia te take e kiia whānuitia ana ko te rauemi paearu mō te kiriata motuka kounga teitei.
Tērā pea ka whai hua tonu te PCU ina whakaarohia e te kaupapa ētahi āhuatanga taumata-pūmua pēnei i te pumau waiora, te whanonga miihini motuhake rānei. Engari mō te kiriata motuka o waho, ko te pātai matua ko te mahi whaihua i runga i te karāhe, i te peita rānei, kaua ko te ingoa whānau pūmua mata. I roto i taua tikanga, ko te TPU te mea e toa ana nā te mea kua hangaia e te umanga he otinga pakari ake, he rite ki te tono huri noa i a ia.
Whakamutunga
He pūnaha rauemi whai tikanga hangarau te TPU me te PCU, engari kāore i te ōrite te arotau mō ngā mahi motuka. Ka taea e te PCU te tuku i ngā āhuatanga miihini me te waiora kaha, engari ko te TPU, inā koa ko te TPU aliphatic, he rite ake ki ngā tono o te kiriata tiaki motuka nā te mea e whakakotahi ana i te māramatanga, te ātete UV, te ātete rakuraku, me te pumau tae mo te wā roa. Mō tetahi ckaihanga tae matapihi ar, ko te kōwhiringa kaha ake ko te mea e tino pai ana te mahi i roto i te taiao tūturu, ehara i te mea e ahua matatau ake ana i runga i te pepa whakatakotoranga. I roto i taua whakataurite, ko te TPU tonu te tūāpapa rauemi kua tino whakamātauhia mō ngā hua kiriata kounga teitei.
Ngā Pātai Auau
He aha te rerekētanga matua i waenga i te kiriata TPU me te kiriata PCU?
He whānau whānui o te polyurethane thermoplastic te TPU, engari ko te PCU ia e pā ana ki te pūnaha polyurethane e ahu mai ana i te polycarbonate e whakamahia ana i te mākete. Kua roa ake te TPU e whakamahia ana hei tiaki i ngā mata o ngā motuka.
He aha te nuinga o te wā e pai ake ai te TPU i roto i te kiriata motuka?
Nā te mea he hononga kaha tō te TPU aliphatic ki te ātete ki te UV, te ātete ki te karawarawa, te ātete ki te rakuraku, me te pumau o te tae, koinei ngā whakaritenga matua mō te tiakitanga o waho o ngā motuka.
He painga anō kei a PCU?
Āe. Ka taea e ngā pūnaha polyurethane e hangai ana ki te polycarbonate te whakaatu i ngā āhuatanga miihini kaha me te pumau waikura, nō reira ka pai pea mō ētahi tono hangarau, tono motuhake rānei.
He pai te TPU polycaprolactone mō te kiriata motuka?
Ka taea e ia te tuku ngāwari, engari ko tōna pirau koiora me ētahi atu āhuatanga rauemi he mea nui ake mō ngā tono hauora, pumau rānei, i te tiaki i ngā taha waho o te motuka mō te wā roa. Kua whakaatuhia hoki e ētahi kiriata polyurethane PCL-based te aro ki te pirau wai.
