Ko te nuinga o tēnei tuhinga e matapakihia ana ngā āhuatanga, te whakataurite mahi me te whakamahinga o ngā elastomers thermoplastic TPE me te TPU rauemi waea me te taura.

01 Te whakamahinga o te TPE i roto i te mara o te waea me te taura

Ko te TPE e pā ana ki tētahi elastomer thermoplastic me te SEBS hei kapia matrix. Ko te SEBS he copolymer poraka i hangaia mai i te styrene (S)-ethylene (E)/butene (B)-styrene (S).

Ka whakakīia ngā hononga takirua i roto i te SEBS, arā, te SBS, e te hauwai, nō reira he pai te ātete o te SEBS ki te huarere, te ātete ki te wera, te ātete ki te pēhanga me ngā āhuatanga miihini tino pai.

(1) He tino pai te mahi ārai hiko o ngā hua SEBS, kāore e pāngia e te paitini, he ātete ki te huarere me te koroheketanga, he ngāwari me te kaha teitei, ā, he whānui te awhe pāmahana. He rauemi pai ēnei mō te hanga uhi o waho me ngā rīpene ārai o ngā waea me ngā taura. Ko te nuinga o te wā ka whakamahia i roto i ngā taunga atamai pūkoro me ngā taputapu kāinga me ētahi atu mara.

I tēnei wā, kua noho hei ia te whakakapinga o te PVC i roto i te ao o ngā waea ngaohiko iti (pērā i ngā taura paneoro, ngā taura rihi, ngā taura USB, ngā taura oro/ataata, ngā taura rorohiko, me ētahi atu).

(2) Nā te mea he tere te whakahou me te poto o te ora ratonga o ngā hua hiko kaihoko, i te taenga mai o te wā o te whakapai ake i te whakamahinga, he nui te wāhi e taea ai te whakawhanake i ngā hua e pā ana ki te SEBS i roto i tēnei ahumahi.

I te pikinga ake o ngā tono mō te ātete ahi taura me te mahi tiaki taiao i te kāinga me tāwāhi, kei te piki haere tonu te taumata kai a te tangata, ā, kei te piki haere te ia o ngā hua SEBS aukati mura mahi teitei ki te whakakapiKo tēnei taura Kei te piki haere te kitea o ngā papa pēnei i te PVC me te CPE i ngā rā kei te heke mai, ā, he whānui hoki ngā tirohanga mō ngā tono ā muri ake nei. I tēnei wā, he nui te hiahia o te mākete mō te whakarerekētanga ātete mura SEBS me te whanaketanga mahi-teitei.

Rauemi TPE mahi motuhake: I te whakamahinga me te whanaketanga o ngā hangarau hou o ngā rauemi TPE, ko te mahi motuhake o nāianei ko te TPE kawe hiko, te TPE ārai-patū, te rauemi ārai TPE, te XLTPO honohono-ira, te TPE ātete-teitei, te TPE ātete-mumura teitei, me ētahi atu.

02 Te whakamahinga o te TPU i roto i te mara o te waea me te taura

Ko te elastomer polyurethane thermoplastic TPU, he copolymer poraka rārangi i hangaia mā te tauhohenga o te diisocyanate me te polyol macromolecular, te mekameka whakaroa/whakawhiti me te iti o ngā tāpiringa. Ko tētahi he rauemi polyurethane te nuinga, ko tētahi he momo polyether te nuinga.

He poraka pūhui te nuinga o te wā, ā, ko te PU e whiwhi ana mā te tauhohe i te polyol mekameka-roa me te isocyanate ka whakamahia hei wāhanga ngohengohe, ā, ko te PU e whiwhi ana mā te tauhohe i te diol mekameka-poto me te isocyanate ka whakamahia hei wāhanga mārō.

Ko ngā tono a ngā elastomers TPU i roto i ngā waea me ngā taura e whai ake nei:

03 Te whakataurite i te mahi a ngā rauemi waea me te taura TPE me te TPU

(1) He kaha ake te TPU i te TPE, he kaha kume me te tere roa: Ko te kaha kume o te TPU e 2 ki te 3 ngā wā i te rapa maori me te rapa hangai, ā, he pai te ātete piko o te TPU; he pai te ātete kakahu, ko te uara kakahu o Taber he 0.35-0.5mg, koinei te mea iti rawa i roto i ngā kirihou, nō reira he pai te ātete pakaru kiri.

(2) Te āhua o te TPE me te TPU me te mahi ngohengohe: Ka taea e te TPE te whakarerekē i te pakeke me te ngāwari mai i te whānuitanga o te 0 nekehanga ki te 99A, ko te whānuitanga o te pakeke o te TPU he 60~95A, ā, ka mau tonu te ngāwari ina neke ake te pakeke i te 85A. He āhuatanga tēnei kāore i ētahi atu elastomers, nō reira he kaha tautoko kawenga teitei a te TPU me te pānga momi me te tuku pai; he tino rerekē te āhua o te rua i roto i ngā whānuitanga pakeke rerekē, ā, ka urutau ki ngā wā rerekē e ai ki ngā whakaritenga; he nui te ngaronga ngāwari o te TPE i ngā wā pakeke teitei.

(3) He pai te ātete wai o te Polyether TPU me te TPE, engari he ngoikore te ātete wai o te polyester TPU; he pai ake te ātete hinu o te TPU i te TPE.

(4) He iti te ātete UV o te polyester TPU, ā, he ngāwari ki te kōwhai. Nā te mea kua honoa te mowhiti benzene o te wāhanga mārō polyurethane me te kaihoko whakamaroke kakara ki te ester waikawa carboxylic, ka puta he waikura me te whakaritenga anō, ka hanga he hanganga quinone me ngā rōpū chromogenic, ā, ka hangaia he hononga kore-māku i roto i te wāhanga polymer; i raro i te mahi a ngā hihi ultraviolet, ka whakaratohia he pūngao "ngā rauropi kore utu" mō te tauhohenga huringa tae, e whakarato ana i te pūngao nui hei whakangaro i ngā hononga matū o te nuinga o ngā polymer, hei whakaoho i te tauhohenga waikura aunoa, ā, ka puta te koroheketanga me te pirau.

He pai ake te mahi kōwhai o te TPU polyether i tērā o te TPU polyester. Ka taea e ia te whakapai ake i te kaha ārai-UV i muri i te whakarerekētanga, kia kore ai e kōwhai i roto i te 1 ki te 2 tau. Ko te ārai-UV o te TPE he pai ake i tērā o te TPU, nō reira he pai ake te TPE ātete-tae i tērā o te TPU.

Hei whakarāpopototanga, he pai ngā painga o ngā TPU polyether ki te ātete ki te waikura, ki te harore, ki te pakari me te mahi pāmahana iti. Ko ngā painga o ngā TPU polyester ko te kaha kume teitei, te ngāwari, te ātete ki te kakahu, te ātete ki te whakarewa, te ātete ki te waikura me te ātete ki te pāmahana teitei.

04 Te tukatuka me te hanga i ngā rauemi waea me te taura TPE me te TPU me te whakatairite utu

Te whakataurite i te tukatuka me te hanga rauemi waea me te taura TPE me te TPU:

(1) He tino ngāwari te mimiti i te wai ki te TPU. Me whakamaroke i te 100℃*3~4H i mua i te tukatuka, ko te TPE ia ka whakamarokehia i te 70~80℃*2H;

(2) Ngā whakaritenga TPU mō ngā mīhini whakaputa. He pai ngā mīhini whakaputa kotahi-tīwiri-toru-wāhanga me te ōwehenga L/D i waenga i te 20-30 me te ōwehenga kōpeketanga i waenga i te 2-4 mō te tukatuka TPU; ko te āputa i waenga i ngā tīwiri me ngā paipa rauemi he tata ki te 0.1-0.2mm. Me karo te hoahoa tīwiri tino pai i te waku nui me te wera nui, ka pirau, ka pakaru hoki te rauemi, ā, ka whakaiti i ngā āhuatanga miihini o te hua.

Ko te tere o te tīwiri e whakawhirinaki ana ki te whānui o te tīwiri. Nā te mea he tairongo te TPU ki te parai me te tapahi, ka taea e te tere nui rawa te arahi ki te pakaru o te TPU. Ki te iti rawa, ka arahi hoki ki te pakaru nā te roa o te wā noho. I te nuinga o te wā, ka whakatakotoria te tere o te tīwiri ki te awhe 25-60rpm, ko te TPE ia me whakamahi i te extruder wetekina.

(3) I mua i te tīmatanga o te TPU, kia tino horoia te tīwiri, te pane mīhini me te rango tīwiri kia kore he kokonga mate. Kua oti ngā whakaritenga katoa, pērā i te whakarite hua haurua-oti, te tā me te patuiro, me ētahi atu. Ko te taahiraa whakamutunga ko te whakatuwhera i te hua kua oti i mua i te kukume i te hopper kia tukuna te rauemi ki te tīwiri. I te wāhanga tuatahi o te tīmatanga o te mīhini, ngana ki te whakaiti i te wā noho o te rapa i runga i te tīwiri. I muri i te tukunga o te rauemi, ka tere te tīmata o te mīhini i roto i te 5 meneti. Me whakahaere pai tēnei wā nui i te tīmatanga. Kia aro ki te ota, ā, ka rua ngā hua ka puta me te haurua o te kaha.

(4) Kāore te TPE e pāngia e te kutikuti, ā, e kore e pirau wawe mēnā ka roa te noho. He māmā ake te tukatuka.

Te whakataurite i ngā utu tukatuka o ngā rauemi waea me te taura TPE me te TPU:

(1) Kāore i tino rerekē te utu o te rauemi TPE me te polyester TPU. He paku teitei ake te polyester TPU, engari he tino teitei te utu o te polyether TPU.

(2) Ko ngā mea e toru he iti rawa te mātotorutanga o te TPE, ā, ko te mātotorutanga o te polyether TPU te mea whai muri, me te mātotorutanga nui rawa o te polyester TPU, ā, ko te utu iti rawa hoki mō te whakamahi i te TPE.

Mā te whakataurite i ngā āhuatanga taketake o ngā rauemi TPE me te TPU me te hangarau tukatuka rauemi, he pai, he ngoikoretanga hoki ō rāua. Heoi, mai i te tātaritanga o ngā mekameka ahumahi TPU me te TPE o te whare, he pumau ake, he watea ake te huarahi mākete rauemi mata TPE, ko te nuinga o ngā rauemi mata whakaputa TPU e whakawhirinaki ana ki ngā kawemai, ā, he āhua tawhito te tukanga whakaputa o te whare, nō reira he uaua ki te whakarite i te pumau o te hua. He tino rerekē ngā āhuatanga rauemi mata o ia kaihanga. Me mārama ō tātou hoa elastomer ki te whakahaere i te whanaketanga o te tono me te whakarerekētanga.

Mā te tūhuratanga hōhonu o te hanganga ā-roto o te rauemi, te aroturukitanga wā-tūturu o ngā huringa mahi me te tautuhi tonu i te pumau, ka whakaatuhia te hototahitanga me te manawanui o ngā waea i raro i ngā rohe moana pakari. I te titiro whakamua ki te heke mai, ko te whakapai tonu i ngā rauemi me te hanganga o ngā raina tuku wai i raro i te moana ka whakatakoto i tētahi turanga pakari ake mō te keri me te whakamahi i ngā rauemi moana.
