I roto i te ao whānui o ngā pūmua hangai, ko te polyester tētahi o ngā whānau tino maha ngā whakamahinga, ā, e whakamahia whānuitia ana. Heoi anō, ka puta he whakapoauautanga e pā ana ki ngā kupu polyester "kūkū" me te "korekū". Ahakoa he wāhanga o te ingoa kotahi, he rerekē rawa ō rāua hanganga matū, ō rāua āhuatanga, me ā rāua whakamahinga whakamutunga.
Ehara i te mea he mea mātauranga anake te mārama ki tēnei rerekētanga—he mea nui hoki mā ngā kaihangarau, mā ngā kaihoahoa hua, mā ngā kaihanga, me ngā tohunga hokohoko te whiriwhiri i te rauemi tika mō te mahi, kia pai ai te mahi, te pakari, me te whai hua o te utu.
Mā tēnei aratohu tino mārama e whakamārama ēnei momo pūmua nui e rua, ka hoatu ki a koe te mōhiotanga e hiahiatia ana hei whakatau whai whakaaro mō tō kaupapa e whai ake nei.
Te Rerekētanga Matua: Kei roto katoa i ngā Here Matū
Ko te rerekētanga matua kei roto i tō rātou tuara ngota, inā koa ko ngā momo here waro-waro e kitea ana.
● Polyester Kore-mākū (UPR):Koinei te "polyester" e tino kitea ana, e mōhiotia whānuitia ana hoki i roto i te umanga hiato. Kei roto i tōna mekameka ngota ngā hononga takirua tauhohe (C=C). Ko ēnei hononga takirua ngā pūwāhi "kore-mākū", ā, ka mahi hei pae honohono pea.UPRKo te tikanga he kapia matotoru, he rite ki te tirikara, he wai i te pāmahana rūma.
● Polyester Kūkū (SP):E ai ki te ingoa, he hononga takitahi (CC) te pūtake o tēnei pūhui. Kāore he hononga takirua tauhohe e wātea ana mō te hononga whakawhiti. Ko ngā polyesters kukū he kirihou wera raina, he taumaha ngota teitei, he totoka i te pāmahana rūma.
Whakaarohia pēnei: Ko te Polyester Taumaha he huinga pereki Lego me ngā pūwāhi hononga tuwhera (ngā hononga takirua), kua rite ki te raka tahi me ētahi atu pereki (he kaihoko hononga whakawhiti). Ko te Polyester Taumaha he huinga pereki kua honoa kētia hei mekameka roa, totoka, pumau.
Ruku Hōhonu: Polyester Kore-mākū (UPR)
Ngā Resin Polyester Kore-Makuku He pūmua whakawerawera ngā (UPR). Me whai tauhohenga matū hei whakamaroke mai i te wai hei totoka mārō, ka taea te whakauru.
Te Matū me te Tukanga Whakaora:
UPRngā kapiaka hangaia mā te tauhohenga o te diol (hei tauira, te propylene glycol) me te ranunga o te waikawa dibasic kua kōtuitia me te waikawa kāore i kōtuitia (hei tauira, te Phthalic Anhydride me te Maleic Anhydride). Ko te Maleic Anhydride te pūtake o ngā hononga takirua nui.
Ka puta te mahi makutu i te wā e whakamaroke ana. TeUPRkapiaka konatunatua ki tētahi monomer tauhohe, ko te Styrene te nuinga. Ina he whakakorikori (he peroxide waro pērā iMEKP) ka tāpirihia, ka tīmatahia he tauhohenga whakapūhui rauropi kore utu. Ka honoa e ngā ngota styrene te taha tataUPRngā mekameka mā roto i ō rātou hononga takirua, ka hanga he whatunga matotoru, toru-ahu. Kāore e taea te whakakore i tēnei tukanga.
Ngā Āhuatanga Matua:
Kaha Mīhini Tino Pai:Ina rongoatia, he mārō, he pūmau.
Ātete Matū me te Wera Pai Rawa:He tino ātete ki te wai, ki ngā waikawa, ki ngā kawakore, me ngā whakarewa.
Te Pūmautanga o te Ahu:He iti te mimiti i te wā e whakamaroke ana, inā koa ina whakakahangia.
Ngāwari o te Tukatuka:Ka taea te whakamahi i roto i ngā momo tikanga maha pēnei i te whakatakoto-ā-ringa, te rehu-ā-ringa, te hanga whakawhiti kapia (RTM), me te pultrusion.
Whai hua te utu:He iti ake te utu i te nuinga o te wāepoxykapiame ētahi atu kapia mahi-teitei.
Ngā Taupānga Matua:
UPRsko rātou te hoiho mahi o tekirihou whakakaha karāhe (FRP) ahumahi.
Moana:Ngā takere me ngā papa o te poti.
Te kawe waka:Ngā panera tinana waka, ngā whakapaipai taraka.
Te Hanganga:Ngā panera whare, ngā papa tuanui, ngā taputapu horoi (ngā kaukau, ngā ua).
Ngā Paipa me ngā Tāke:Mō ngā tipu matū me ngā tipu maimoatanga wai.
Kohatu Horihori:Ngā mata totoka mō ngā papa kaute.
Ruku Hōhonu: Polyester Kūkū (SP)
Ngā Polyester KūkūHe whānau pūmua kirihou wera ēnei. Ka taea te whakarewa mā te wera, te hanga anō, me te whakapakeke i te whakamatao, he tukanga ka taea te huri.
Te Matū me te Hanganga:
Ngā momo tino noa ongā polyesters kua mākūko te PET (Polyethylene Terephthalate) me te PBT (Polybutylene Terephthalate). Ka hangaia ēnei mā te tauhohenga o te diol me te waikawa diacid kua kōtuitia (hei tauira, te Waikawa Terephthalic, te Dimethyl Terephthalate rānei). Kāore he pae mō te hononga whakawhiti o te mekameka hua, ka waiho hei pūmua raina, ngāwari.
Ngā Āhuatanga Matua:
Te Tino Pakari me te Ātete Pānga: He tino pakari, he ātete hoki ki te ngatata.
Ātete Matū Pai:He ātete ki te whānuitanga o ngā matū, ahakoa kāore i te whānui pērā i teUPRs.
Te āhua wera:Ka taea te werohanga, te whakaputa ki waho, me te hanga i roto i te wera.
Ngā Āhuatanga Ārai Pai rawa atu:E mōhiotia ana a PET mō ōna āhuatanga ārai hau me te makuku.
He Ātete Pai ki te Mau me te Ātete ki te Waro:He mea e tika ai mō ngā wāhanga e neke ana.
Ngā Taupānga Matua:
Ngā polyesters kua kōkōtiahe mea noa i roto i ngā kirihou hangarau me ngā takai.
Tākai:Ko te PET te rauemi matua mō ngā pounamu wai me te houra kirihou, ngā ipu kai, me ngā putea mirumiru.
Ngā kakahu:Ko te PET te "polyester" rongonui e whakamahia ana i roto i ngā kākahu, ngā whāriki, me ngā taura potae.
Ngā Kirihou Hangarau:E whakamahia ana te PBT me te PET mō ngā wāhanga motuka (ngā taputapu, ngā pūoko, ngā hononga), ngā wāhanga hiko (ngā hononga, ngā pana), me ngā taputapu kaihoko.

Me pēhea te whiriwhiri: Ko tēhea te mea tika mō tō kaupapa?
Ko te kōwhiringa i waenga iUPRā, onge noa iho te raruraru o te SP ina tautuhia e koe ō hiahia. Pātai atu ki a koe anō ēnei pātai:
Kōwhiria te Polyester Kore-Makuku (UPR) mēnā:
Me whai wāhanga nui, mārō, kaha hoki koe ka hangaia i te pāmahana rūma (pēnei i te anga poti).
He mea nui te ātete matū teitei (hei tauira, mō ngā tāke rokiroki matū).
Kei te whakamahi koe i ngā tikanga hanga hiato pērā i te whakatakoto-ā-ringa, te pultrusion rānei.
He mea nui te utu hei ārahi.
Kōwhiria te Polyester Kūkū (SP – PET, PBT) mēnā:
Me whai wāhanga pakari, ātete ki te pānga (pēnei i te taputapu, i te whare tiaki rānei).
Kei te whakamahi koe i ngā mahi hanga nui pēnei i te whakarewa werohanga.
He mea nui te hangarua, te whakamahi anō rānei i ngā rauemi mō tō hua, mō tō waitohu rānei.
Me whai ārai pai rawa atu koe mō te tākai i ngā kai me ngā inu.
Whakamutunga: Ngā Whānau e Rua, Ingoa Kotahi
Ahakoa he rite te tangi o te polyester "kūkū" me te "korekū" (unsaturated), e tohu ana rāua i ngā peka e rua o te whānau polymer me ngā ara rerekē.Polyester Kore-Makuku Resinko ia te toa whakawerawera o ngā hiato kaha-teitei, ātete-waikura. Ko te Polyester Kūkū te mea tino kaha ki te whakawerawera i muri i ngā kirihou me ngā kakahu tino noa o te ao.
Mā te mārama ki ngā rerekētanga matū matua o aua rauemi, ka taea e koe te neke atu i te whakapoauautanga me te whakamahi i ngā painga ahurei o ia rauemi. Mā tēnei mōhiotanga koe e āhei ai ki te tohu i te pūmua tika, ka hua ake he hua pai ake, he tukanga kua arotauhia, ā, i te mutunga, he angitu nui ake i te mākete.
