Polybutylene terephthalate(PBT)) he polyester kukū kirihou-wera haurua-kiriata, he mā te nuinga o te wā, he totoka kirikiri i te pāmahana rūma, e whakamahia whānuitia ana i roto i te hanga rauemi paninga tuarua kirihou-wera taura whatu.
He tukanga tino nui te paninga tuarua o te muka whatu i roto i te hanga muka whatu. He māmā noa iho, mā te tāpiri i tētahi paparanga tiaki ki te paninga tuatahi o te muka whatu, ki te paparanga ārai rānei, ka taea te whakapai ake i te kaha o te muka whatu ki te ātete i te ahotea roa me te ahotea radial, ā, ka whakahaere i te tukatuka muri o te muka whatu. Nā te mea he tata te rauemi paninga ki te muka whatu, he nui ake tōna pānga ki te mahi a te muka whatu, nō reira me iti te tauwehenga whānui raina o te rauemi paninga, he teitei te tioata i muri i te whakaputanga, he pai te pumau matū me te wera, he maeneene ngā pakitara o roto me waho o te paparanga paninga, he kaha kume me te modulus a Young, ā, he pai te mahi tukanga. E rua ngā wāhanga o te paninga muka: te uhi korekore me te uhi piri. I roto i ēnei, ko te rauemi uhi korekore e whakamahia ana i roto i te paninga uhi korekore ko te paparanga paninga tuarua e whakaputahia ana i roto i te āhua ringaringa korekore i waho o te muka paninga tuatahi.
He rauemi ringaringa korekore noa te PBT, he pai rawa ngā āhuatanga hanga me te tukatuka, he iti te mimiti makuku, ā, he nui te utu. E whakamahia whānuitia ana i roto iPBTwhakarerekētanga, tuhi waea PBT, anga, tuhi kiriata me ētahi atu mara. He pai ngā āhuatanga miihini o te PBT (pēnei i te ātete kume, te ātete piko, te ātete pēhanga taha), te ātete whakarewa pai, te ātete hinu, te ātete waikura matū, me te whakapiri muka, te whakapiri taura me ētahi atu wāhanga o te taura he hototahi pai, ā, he pai te mahi tukatuka hanga, he iti te mimiti makuku, he utu-whai hua. Ko ōna paerewa mahi hangarau matua ko: te matotoru ā-roto, te kaha hua, te modulus rapa kume me te piko, te kaha pānga (notch), te tauwehenga whānui raina, te mimiti wai, te ātete waikura me ētahi atu.
Heoi, nā te panonitanga o te hanganga taura muka me te taiao whakahaere, he nui ake ngā whakaritenga e tukuna ana mō te pūwero muka. Ko te tioata teitei, te iti o te whakahekenga, te iti o te tauwehenga whānui raina, te pakari teitei, te kaha pēhi teitei, te ātete matū pai rawa atu, te pai o te mahi tukatuka, me ngā rauemi iti te utu, koinei ngā whāinga e whaia ana e ngā kaihanga taura whatu. I tēnei wā, he ngoikoretanga kei roto i te tono me te utu o te ngongo kurupae i hangaia mai i te rauemi PBT, ā, kua tīmata ngā whenua ke ki te whakamahi i ngā rauemi koranu PBT hei whakakapi i ngā rauemi PBT parakore, he pai te pānga me te mahi. I tēnei wā, he maha ngā kamupene taura nui o te motu kei te kaha te whakarite, me te hiahia tonu ngā kamupene rauemi taura ki te auahatanga hangarau, te rangahau me te whakawhanake i ngā rauemi hou.
Ae, i roto i te umanga PBT whānui, he iti noa te wāhanga o te mākete PBT e whakamahia ana mō ngā taura muka whatu. E ai ki ngā puna o te umanga, i roto i te umanga PBT katoa, ko te nuinga o te wahanga mākete e whakamahia ana e ngā mara e rua o te motuka me te hiko. Ko ngā hononga, ngā whakawhiti me ētahi atu hua i hangaia mai i ngā rauemi PBT kua whakarerekētia e whakamahia whānuitia ana i roto i ngā taputapu motuka, hiko me te hiko, ngā taputapu miihini me ētahi atu mara, ā, he tono anō hoki a PBT i roto i te mara kakahu, pērā i te mea he mea hanga anō hoki ngā paraihe niho mai i te PBT. Ko ngā tono whānui o te PBT i roto i ngā mara rerekē:
1. Ngā mara hiko me te hikohiko
He whānuitia te whakamahinga o ngā rauemi PBT i roto i ngā mara hiko me te hiko, pērā i ngā pūwero hiko, ngā mono, ngā pūwero hiko me ētahi atu wāhanga hiko o te whare. Nā te mea he pai te mahi ārai wera o te rauemi PBT me te ātete ki te pāmahana teitei, he tino pai mō te anga, te whāriki, te pepa ārai wera me ētahi atu wāhanga o ngā taputapu hiko me te hiko. Hei tāpiri, ka taea hoki te whakamahi i ngā rauemi PBT hei hanga i te uhi o muri o te mata LCD, te anga pouaka whakaata me ētahi atu.
2. Te mara o ngā motuka
E whakamahia whānuitia ana hoki ngā rauemi PBT i roto i te ao motuka. Nā ōna painga o te pāmahana teitei, te waikura me te ātete ki te kakahu, e whakamahia whānuitia ana ngā rauemi PBT i roto i te hanga o ngā wāhanga motuka, pērā i te manifold whakauru, te whare papu hinu, te whare pūoko, ngā wāhanga pūnaha parai, me ētahi atu. Hei tāpiri, ka taea hoki te whakamahi i ngā rauemi PBT mō ngā urunga o te nohoanga motuka, ngā tikanga whakatikatika nohoanga, me ētahi atu.
3. Te umanga mīhini
I roto i te umanga mīhini, he maha ngā wā ka whakamahia ngā rauemi PBT hei hanga kakau taputapu, pana, pātene, me ētahi atu. He tino kaha te rauemi PBT me te ātete ki te kakahu, ka taea te tu atu ki ngā kaha mīhini rerekē, ā, he pai te ātete ki te waikura matū, he pai mō ngā wāhanga rerekē i roto i te mara o te umanga mīhini.
4. Te umanga taputapu hauora
He pai te ātete o te rauemi PBT ki te pāmahana teitei, ā, he tino pumau te matū, he mea tino pai mō te hanga taputapu hauora. Hei tauira, ka taea te whakamahi i ngā rauemi PBT hei hanga whare taputapu hauora, paipa, hononga, me ētahi atu. Hei tāpiri, ka taea hoki te whakamahi i ngā rauemi PBT hei hanga ngira hauora, huinga werohanga me ngā momo taputapu rongoā.
5. Te whakawhitiwhiti kōrero whatu
I roto i te ao whakawhitiwhiti kōrero whatu, e whakamahia whānuitia ana te PBT i roto i te hanga taura whatu hei rauemi ringaringa korekore noa. Hei tāpiri, e whakamahia whānuitia ana ngā rauemi PBT i roto i ngā taputapu whatu. Nā ōna āhuatanga whatu pai me te ātete pāmahana teitei, e whakamahia ana ngā rauemi PBT hei hanga hononga muka whatu, anga tohatoha muka whatu, me ētahi atu. Hei tāpiri, ka taea hoki te whakamahi i ngā rauemi PBT hei hanga karāhe, whakaata, matapihi me ētahi atu wāhanga whatu.
Mai i te tirohanga a te umanga katoa, i ngā tau tata nei, kua whakapau kaha ngā umanga e tika ana ki te whakawhanake i ngā momo tono hangarau hou me ngā hua hou, ā, kua whanake te PBT i te huarahi ki te mahi teitei, te mahi me te kanorau. He iti te kaha kume, te kaha piko me te modulus piko o te kapia PBT parakore, kāore e taea te whakamahi whānui i roto i te mara ahumahi, nō reira, mō ngā hiahia o te mara ahumahi, mā te whakarerekētanga o te umanga hei whakapai ake i te mahi a te PBT. Hei tauira, ka tāpirihia te muka karāhe ki te PBT - he painga te muka karāhe o te kaha tono, te tukanga whakakī ngāwari me te utu iti. Mā te tāpiri i te muka karāhe ki te PBT, ka whakauruhia ngā painga taketake o te kapia PBT, ā, ka tino whakapaitia te kaha kume, te kaha piko me te kaha pānga o ngā hua PBT.
I tēnei wā, ko ngā tikanga matua o te kāinga me tāwāhi ko te whakarerekētanga copolymerization, te whakarerekētanga whakakī rauemi inorganic, te hangarau nanocomposite, te whakarerekētanga whakaranu, me ētahi atu, hei whakapai ake i te mahi whānui o te PBT. Ko te whakarerekētanga o ngā rauemi PBT e aro nui ana ki ngā āhuatanga o te kaha teitei, te ātete mura teitei, te iti o te warpage, te iti o te rerenga me te iti o te dielectric.
I te nuinga o te wā, mō te umanga PBT katoa, he nui tonu te tono mō ngā tono i roto i ngā mara rerekē, ā, ko ngā whakarerekētanga rerekē i runga i te tono o te mākete ko ngā whāinga rangahau me te whanaketanga noa o ngā umanga umanga PBT.
