Ngā Pūrongo - Ngā Otinga mō ngā Wero Whakairoiro Noa, me te Whakarei ake i te Whakamarie, te Ataahua me te Pakari i roto i te Hoahoa Pa-Ngāwari

Te Whanaketanga: Te Whakakorikori TPE

He rauemi maha ngā mahi a te TPE, arā, te thermoplastic elastomer, e whakakotahi ana i te ngāwari o te rapa me te pakari o te kirihou. Ka taea te hanga, te whakaputa tika rānei, me te whakamahi i te TPE-S (styrene-based thermoplastic elastomer) e whakamahia whānuitia ana, e whakauru ana i ngā SEBS, SBS rānei elastomers mō ngā kirihou hangarau thermoplastic. E kiia ana te TPE-S ko te TPE, ko te TPR rānei i roto i te umanga elastomer.

Heoi, ko te TPE overmolding, e mōhiotia ana ko te thermoplastic elastomer overmolding, he tukanga hanga e uru ana ki te hanga i tētahi rauemi thermoplastic elastomer (TPE) ki runga i tētahi papa, i tētahi rauemi turanga rānei. Ka whakamahia tēnei tukanga hei whakakotahi i ngā āhuatanga o te TPE, pērā i tōna ngāwari me tōna ngawari, me ngā āhuatanga motuhake o te papa kei raro, arā, he kirihou pakari, he konganuku, he rauemi kē atu rānei.

E rua ngā momo o te whakakī TPE, ko tētahi he whakakī tūturu, ko tētahi he whakakī rūpahu. Ko ngā hua whakakī TPE he kakau me ngā hua kakau, nā te mea he pai te pā o te rauemi kirihou ngohengohe TPE, ka whakarei ake te whakaurunga o te rauemi TPE i te kaha hopu me te pā o te hua. Ko te mea e wehewehe ana ko te reo o te rauemi whakakī, ko te tikanga he whakakī werohanga tae-rua, he whakakī werohanga tuarua rānei hei hipoki i te kirihou ko te whakakī tūturu, ko te whakakī pere he whakakī rūpahu. I roto i te mara o te whakakī tūturu, ka taea te hono i te rauemi TPE ki ētahi kirihou whānui, pērā i te PP, PC, PA, ABS me ētahi atu, he whānuitia ngā whakamahinga.

Ngā Painga o te Rauemi TPE

1. Ngā Āhuatanga Ārai-Paheke: Ka whakaratohia e te TPE he mata kore-paheke, ka whakarei ake i te kaha pupuri mō ngā momo hua pēnei i ngā kakau karapu korowha, ngā kakau taputapu, ngā kakau paraihe niho, me ngā taputapu hākinakina TPE kua whakakikoruatia.
2. Ngāwari me te Whakamarie: Ko te āhua ngawari o te TPE, ina whakamahia hei paparanga o waho i runga i ngā rauemi rapa mārō, ka whakarite kia whakamarie, kia kore hoki e piri.
3. Whānui te Awhe Pakari: He whānui te awhe pakeke: Kei waenganui i te 25A-90A te nuinga o te wā, ā, he ngāwari te hoahoa a te TPE, e āhei ai te whakarerekē i te ātete ki te kakahu, te ngāwari, me ētahi atu.
4. Ātete Tino Pai ki te Pakeketanga: He kaha te ātete a te TPE ki te koroheketanga, e whai wāhi ana ki te roa o te ora o ngā hua.
5. Whakaritenga Tae: Mā te TPE ka taea te whakarite tae mā te tāpiri i te paura tae, te tae masterbatch rānei ki te hanganga rauemi.
6. Ngā Āhuatanga Mimi Ru me te Ārai Wai: He kaha te TPE ki te mimi ru me te ārai wai, e pai ai mō te here i ngā wāhi e hiahiatia ana, ā, hei rauemi hiri hoki.

Ngā Take mō te Whakakorikori TPE Kore-Haumaru

1. Te uaua o te tātaritanga kirihou whakakīkī: ko ngā kirihou e whakamahia whānuitia ana ko ABS, PP, PC, PA, PS, POM, me ētahi atu. Ko ia momo kirihou, kei a ia te taumata rauemi whakakīkī TPE e rite ana. I te taha whakataurite, ko te PP te takai pai rawa atu; ko te PS, ABS, PC, PC + ABS, PE te tuarua, engari kua tino pakari te hangarau takai, kia kore ai e uaua te whakatutuki i te whakakīkī totoka; ka nui ake ngā uauatanga o te whakakīkī nairona PA, engari i ngā tau tata nei kua tino ahu whakamua te hangarau.

2. Ko te whānuitanga matua o te pakeke TPE mō te whakakikorua kirihou: ko te pakeke o te whakakikorua PP he 10-95A; ko te pakeke o te whakakikorua PC, ABS he 30-90A; ko te pakeke o te whakakikorua PS he 20-95A; ko te pakeke o te whakakikorua nairona PA he 40-80A; ko te pakeke o te whakakikorua POM he 50-80A.

Ngā Wero me ngā Otinga i roto i te TPE Overmolding

1. Te Whakatakotoranga me te Whakakore: Whakapai ake i te hototahitanga TPE, whakarerekētia te tere me te pēhanga werohanga, me te arotau i te rahi o te kuaha.

2. Te Whakakorenga Kino: Whakarerekētia te rauemi TPE, tāpirihia rānei he kakano pokepokea ai kia iti ake te kanapa.

3. Te Mā me te Piri: Whakahaerehia ngā rahinga tāpiri hei whakatika i te putanga hau mai i ngā tāpiringa ngota iti.

4. Te Whakarerekētanga o ngā Wāhanga Kirihou Mārō: Whakatikatikahia te pāmahana, te tere, me te pēhanga werohanga, whakakahangia rānei te hanganga o te pokepokea ai.

Te Anamata: Te Whakautu a Si-TPV ki ngā Wero Noa i roto i te Overmolding kia Pumau te Ataahua
