Ngā Mea e Hiahiatia ana e Ngā Kaihanga kia Mōhio mō te Hangarau TPU Kua Whakarerekētia me ngā Otinga Rauemi Auaha mō ngā Taura me ngā Ngongo Puranga Utu EV!

1. Hangarau TPU (polyurethane wera) kua whakarerekētia

He mea nui te whakarerekētanga o ngā mata TPU mō te whakawhanake i ngā rauemi ka taea te whakanui ake i te mahi i roto i ngā tono motuhake. Tuatahi, me mārama tātou ki te Pakeke me te Āhua TPU. Ko te pakeke TPU e pā ana ki te ātete o te rauemi ki te kōpiko, ki te whakarerekētanga rānei i raro i te pēhanga. Ko ngā uara pakeke teitei ake e tohu ana i tētahi rauemi pakari ake, ko ngā uara iti ake e tohu ana i te ngāwari ake. Ko te Āhua e pā ana ki te kaha o te rauemi ki te whakarerekē i raro i te ahotea me te hoki ki tōna āhua taketake i te tangohanga o te ahotea. Ko te āhua teitei ake e tohu ana i te pai ake o te ngāwari me te manawanui.

I ngā tau tata nei, kua arohia te whakaurunga o ngā tāpiringa silicone ki roto i ngā whakatakotoranga TPU hei whakatutuki i ngā whakarerekētanga e hiahiatia ana. He mea nui te mahi a ngā tāpiringa silicone ki te whakapai ake i ngā āhuatanga tukatuka me te kounga o te mata o te TPU me te kore e pā kino ki ngā āhuatanga papatipu. Ka puta tēnei nā te hototahitanga o ngā ngota silicone ki te matrix TPU, e mahi ana hei kaiwhakangawari me te hinu whakahinuhinu i roto i te hanganga TPU. Mā tēnei ka māmā ake te nekehanga mekameka me te whakaiti i ngā kaha intermolecular, ka hua ake he TPU ngawari ake, he ngāwari ake me ngā uara pakeke kua whakaitihia.

Hei tāpiritanga, ka mahi ngā tāpiringa silicone hei āwhina tukatuka, hei whakaiti i te waku, hei whakahohe hoki i te rere o te rewa kia maeneene ake. Mā tēnei ka māmā ake te tukatuka me te whakaputa i te TPU, ka whakarei ake i te hua me te whakaiti i ngā utu hanga.

Kua mōhiotia te GENIOPLAST PELLET 345 Siliconmodifier hei tāpiri silicone whai hua i roto i ngā tono TPU. Nā tēnei tāpiri silicone kua whānui ake te whānuitanga o ngā tono mō ngā polyurethane thermoplastic. He nui te tono i roto i ngā taonga kaihoko, ngā motuka, ngā taputapu hauora, ngā paipa wai, ngā ngongo, ngā taputapu hākinakina, ngā kakau kakau, ngā taputapu, me ētahi atu rāngai mō ngā wāhanga TPU whakarewa he pai te āhua, he whakamarie hoki, ā, ka mau tonu te āhua ina roa te whakamahinga.

He rite tonu te mahi a ngā tāpiri kirihou me ngā whakarerekētanga pūmua Si-TPV a Silike ki ō rātou hoa i te utu whaitake. Kua whakaatuhia e ngā whakamātautau he whai hua, he haumaru, he pai hoki te taiao mō ngā tono TPU me ngā pūmua hei whakakapi mō ngā tāpiringa silicone hou.

Ka whakarei ake tēnei tāpiringa silicone i te maeneene o te mata mō te wā roa me te āhua pā, me te whakaiti i ngā tohu rere me te taratara o te mata. He mea nui, ka whakaiti i te pakeketanga me te kore e whakararu i ngā āhuatanga miihini; hei tauira, mā te tāpiri i te 20% Si-TPV 3100-65A ki te 85A TPU ka whakaiti i te pakeketanga ki te 79.2A. Hei tāpiri, ka whakapai ake te Si-TPV i te ātete ki te koroheketanga, te kōwhaitanga, me te paru, ā, ka hoatu he mutunga matte, ka whakarei ake i te ataahua o ngā wāhanga TPU me ngā hua kua oti.

Ka tukatukahia te Si-TPV pērā i te kirihou wera. He rerekē ki ngā tāpiringa silicone tuku iho, ka marara pai, ka horapa hoki puta noa i te hanganga polymer. Ka herea ā-tinana te copolymer ki te hanganga..Kāore koe e manukanuka kei arahi pea koe ki ngā raruraru hekenga (te iti o te 'pua').

2. Ngā Matū TPU Kua Whakarerekētia me ngā Otinga Rauemi Auaha mō ngā Ngongo

He mea nui te whiriwhiri i ngā rauemi tika mō ngā ngongo o roto me ngā ngongo kaukau ngāwari mō te mahi tino pai, te roa, me te ngāwari. Ko ngā ngongo kaukau TPU, hei whakaurunga hou ki te mākete, ka whakarato i te taurite pai o te pakari me te ngāwari, ka taea ai te nekeneke ngāwari me te kore e piko, e raranga rānei. He ātete hoki ki te ngatata, te pakaru, me te turuturu, ka whai wāhi ki te roa o te ora ki te whakataurite ki ngā rauemi tuku iho.

Ahakoa e mōhiotia ana te TPU mō tōna pakari me tōna maha o ngā whakamahinga, ka kitea tonu he hapa. Mā te whakatikatika i te pakeketanga me te whakapai ake i te ngāwari ka taea te whakapai ake i te mahi a ngā ngongo kaukau ngāwari me ētahi atu whakamahinga motuhake. Mō te hunga e rapu ana i te ngāwaritanga teitei, te ātete hurihuri, te pumautanga, me te ataahua, he kōwhiringa pai rawa atu ngā ngongo TPU kua whakapakarihia e Si-TPV. Ko te Si-TPV he whakarerekētanga tāpiri auaha e ahu mai ana i te silicone ka taea te whakakotahi ki te TPU me ētahi atu rauemi hei whakaiti i te pakeketanga me te whakanui ake i te ngāwaritanga, te ngāwaritanga, me te pakari i roto i ngā hua whakamutunga, pēnei i ngā rauemi ngongo.

Hei tāpiritanga, he rauemi iti te kakara o te Si-TPV thermoplastic elastomer, kāore he plasticizer, e ngāwari ana te hono atu ki ngā papa porotaka pēnei i te PC, ABS, me te PA6. Nā tōna ngawari ka pai mō ngā hononga paipa ngāwari i roto i ngā pūnaha kaukau me te wai, e whakaatu ana i te kaha nui o te tono.

Hei tauira, ka whakamahia e te ngongo kaukau he uho Si-TPV ngohengohe, he pai mō te kiri, e whakarato ana i te pakari, te ātete ki te pēhanga me te pāmahana teitei, te ātete matū, me te ngāwari me te kore e piko, e whakarite ana i te wheako kaukau roa me te whakamarie. Ko te āhua ā-wai o Si-TPV, me ōna āhuatanga ngāwari ki te horoi, e whakarei ake ana i tōna ataahua.

Ngā Painga Matua o te Si-TPV i roto i ngā Whakamahinga Ngongo:

● He hoahoa ātete-kikī, ātete-wai hoki

● Ātete ki te pakū me te rakuraku

● He mata maeneene, he pai mō te kiri

● Tino ātete ki te pēhanga, e whakapūmau ana i te kaha kume

● Haumaru, ngāwari hoki te horoi

Hei whakarāpopototanga, ko ngā matū TPU kua whakarerekētia, inā koa ko ērā e whakauru ana i te Si-TPV, e tuku ana i ngā otinga matatau mō ngā rauemi ngongo me ngā hononga paipa i roto i ngā pūnaha kaukau me te wai, e tutuki ai ngā tono o ēnei rā, me te whakarei ake i te wheako kaiwhakamahi.
3. Te Arotau i ngā Taura Pūnaha Utu Waka Hiko: Ngā Otinga Whai Hua me te TPU Kua Whakarerekētia

Hei whakatika i ngā wero o te tere hurihuri o te whiri me te pakaru o ngā taura pou, mā te whakauru i te Si-TPV (ngā elastomer silicone-based thermoplastic kua whakamomonatia) ki roto i ngā hanganga TPU ka tukuna he otinga auaha hei whakarei ake i te mahi me te roa o ngā taura utu waka hiko (EV).

● Te Maeneene me te Ātete o te Mata kua Whakapai ake:

Mā te whakauru i te 6% Si-TPV ka pai ake te maeneene o te mata o te TPU, ka nui ake te ātete ki te rakuraku me te pakū. Ko te hua o tēnei whakarerekētanga he ātete ake ki te piri o te puehu, ka puta he āhua kore-piri e āwhina ana ki te ātete i te kohikohinga paru.

● Te Āhuatanga me ngā Āhuatanga Hangarau kua Whakapaitia:

Mā te tāpiri atu i te neke atu i te 10% Si-TPV ki ngā whakatakotoranga TPU ka whakangawari i te rauemi, ka whakanui ake hoki i tōna ngāwari. Ehara i te mea ka pai ake ngā āhuatanga miihini o tēnei whakarerekētanga engari ka āwhina hoki i ngā kaihanga ki te waihanga i ngā taura utu tere kounga teitei, pakari, me te whai hua e tu atu ana ki te whakamahinga o ia rā.

● Ngāwari te Pā me te Ātaahua o te Tirohanga:

Mā te whakauru i te Si-TPV ki roto i te TPU ka whakarei ake i te āhua pā ngāwari o ngā taura utu EV, ā, ka tutuki hoki he āhua matte ātaahua ki te titiro. Ka tutuki i tēnei huinga o te whakamarie pā me te pakari ataahua ngā tumanakohanga a te kaihoko mō ngā taura mahi teitei.

Ka whakamahia e ēnei otinga ngā āhuatanga ahurei o Si-TPV hei whakarei ake i te mahi me te wheako kaiwhakamahi o ngā taura pūnaha utu EV e hangai ana ki te TPU, ā, hei whakamana i te umanga waka hiko me ngā rauemi auaha, pumau hoki.
He aha te mea ngaro ki te mahi tino pai i runga i te TPU?

Ko te whakatutuki i te mahi teitei o te Thermoplastic Polyurethane (TPU) me whakarerekē āta te rauemi. He tukanga maha-āhua te kimi i te taurite i waenga i te whakaiti i te pakeke me te whakapakari i te ātete ki te pakū, me ētahi atu mahi nui. Ka taea e ngā kaihanga TPU te arotau i ngā āhuatanga o te rauemi mā te whiriwhiri i ngā ranunga tika, te whakauru i ngā whakakī ātete-pakū, ngā mea whakakoi kirihou, me ngā mea whakangawari, me te whakahaere tika i ngā tawhā whakaputa kia tutuki ai ngā whakaritenga motuhake o ngā tono rerekē.

Mā te whakauru i te Si-TPV ki roto i ā rātou hanganga, ka taea e ngā kaihanga te whakarei ake i te mahi a te TPU. Ka whakapai ake tēnei tāpiri kirihou auaha me te whakarerekētanga polymer i ngā āhuatanga matua pērā i te ngawari, te ngāwari, te pakari, te āhua pā, me te whakaotinga o te mata. Nō reira, ka whakawhānui ake i te whānuitanga o ngā tono pea puta noa i ngā ahumahi maha, ka taea ai e ngā kaihanga te whakatutuki i ngā tono mahi rerekē.
