I te tere haere o te whanaketanga o ngā "Whakahoutanga Hou e Whā" o te umanga motuka (Te Māmā, Te Hiko, Te Matauranga), kei te whanake haere ngā kirihou hangarau i roto i te auahatanga mahi kāore i kitea i mua. I roto i ngā momo huarahi kē atu i te whakarewa, ko te **rauemi PP roa muka karāhe whakapakari (PP-LGF)** kua waiho hei whiringa pai mō ngā wāhanga hanganga motuka me ngā wāhanga mahi o roto, nā tōna kaha motuhake, tōna ātete ki te ngenge, me tōna pūmanawa ahurei mō te "whakarewatanga kirihou."

Hei kamupene e aro nui ana ki tēnei mara, ka hangaia e Jurong Best Composite Materials Co., Ltd. ngā raupapa PP-GF30, PP-GF40, me PP-GF50, e kapi tika ana i te whānuitanga o ngā hiahia mai i ngā hanganga kawenga tuarua ki ngā wāhanga angaanga pakari. Kei raro nei, ka rukuhia e mātou te arorau tono motuhake me te uara o ēnei rauemi i roto i ngā wāhanga matua e toru: te turanga rīpene neke, te uhi miihini, me te reera tuanui rā.

I. Te Tūāpapa o te Rīpene Neke (Te Pūtake Tikanga Nekeneke): Te Taurite i waenganui i te Pakari Nui me te Ātete Ngoki

Whakaahuatanga o te Tauira Taupānga:

Kei te pokapū o te papatohu o te waka te turanga o te rīpene whakawhiti. Ehara i te mea ko te kaha whakawhiti a te taraiwa anake te mea e mau ana, engari e mau ana hoki te pūnaha whakawhiti hiko matatini. He taumaha ngā turanga whakarewa tuku iho, ā, he ngāwari ki te pāngia e ngā raruraru NVH (Haruru, Wiri, Kaha).

Otinga Rauemi: PP-GF40 (Te Tauwehenga Koura) Mō tēnei tono, he kōwhiringa utu-pai te PP-LGF me te 40% o te muka karāhe.

Te Mahi Ā-Mīhini: Ki te whakatauritea ki te PP-GF30, ko te tikanga ka eke te PP-GF40 ki te neke atu i te 6000 MPa, ka nui ake te ātete ki te hurihanga. Mā tēnei ka kore te turanga e ngoki, e neke rānei i te wā e panaia ana, e tōia ana e te taraiwa, kia mau tonu ai te ahua o te nekenga ā-mīhini.

Akoranga Take me ngā Hua: I roto i tētahi whakahoutanga tauira, i whakawhitihia e tētahi kamupene hanga waka nui te turanga ki te PP-GF40. I whakaatuhia e ngā hua i roto i ngā whakamātautau huringa wera mai i te -35°C ki te 85°C, kāore i te pupuri noa te PP-GF40 i te pakari e rite ana ki te nairona, engari i whakaitihia hoki ngā utu mā te 20-25%. I tua atu, mā te whakamahi i te iti o te mātotoru o te PP, i tutuki ai te whakahekenga taumaha kotahi-wāhanga neke atu i te 15%.

Ngā Whakaarohanga Whakaputa:

Whakahaere Wāhanga: He āhua uaua te turanga o te rīpene neke me ngā kōhao maha mō te whakairi me te taunga. Ahakoa he pai ake te rere o te PP-GF40 i te PA, me tika te hoahoa kuaha (ko ngā kaitahuri wera kuaha takirere te mea pai) hei whakahaere i te whakatakotoranga muka karāhe me te karo i te wēhanga i puta mai i te whakahekenga anisotropic.

Kaha Hononga: Nā te iti o te polarity o te PP, ki te hiahia he tīwiri pikau kawenga te turanga, he mea tika kia hoahoahia he whakaurunga whakarewa, kia whakamahia rānei he whakarewa ultrasonic hei karo i te pakaru ahotea i puta mai i te miro tīwiri-tāpiri-ake.

II. Taupoki Mīhini (Taupoki Manifold Whakauru / Taupoki Upoko Pūwero): He Pakanga Manawanui i roto i te "Steamer" Pāmahana-Tiketike

Whakaahuatanga o te Tauira Taupānga:

Kei roto i te pokapū o te wāhanga miihini te taupoki miihini, kia roa te pa atu ki te hau wera, te kohu hinu, me ngā pāmahana teitei (120-140°C mō te wā roa). Ko ngā whakaritenga matua ko te ātete roa ki te tawhitotanga wera me te pumau o ngā āhuatanga.

Otinga Rauemi: PP-GF30 (Whakapai ake i te Wera-Whakapūmau)

Ahakoa he momo whakapakari whānui te PP-GF30, me whakarerekētanga motuhake te whakapūmautanga wera-pakeke (Heat Aging Stabilized) mō ngā tono huri noa i te mīhini.

Kaha o te Ngenge i te Mahana Teitei: I roto i te PP muka-karaehe poto tikanga, ka piki ake te nekenekehanga o te mekameka ngota i ngā pāmahana teitei, ka heke tere te pakari. Heoi, ko te hanganga whatunga toru-ahu i hangaia e te muka-karaehe roa PP-GF30 ka hoatu he kaha ngenge pāmahana teitei i te 120°C, he rua te nui ake i te PP noa kua whakapakarihia ki te muka-karaehe poto, ā, he 10% teitei ake i te nairona kua whakapakarihia ki te muka-karaehe, e mōhiotia ana mō tōna ātete wera.

Akoranga Take me ngā Hua: I whakakapia te konumohe e tētahi kaihanga waka Pākehā ki te PP-LGF30 hei uhi whakapaipai mō te mīhini. He mea nui ngā hua: haunga te whakahekenga taumaha neke atu i te 40%, i tino whakaitihia e te rauemi LGF te tuku wiri mīhini auau-teitei ki te kāpini. I paahitia e ia ngā whakamātautau tawhito hau wera 150°C / 1000-hāora me te kore e pakaru, e rerekē rānei te āhua.

Ngā Whakaarohanga Whakaputa:

Iti te Kakara me te Iti te VOC: Ka anga te taupoki miihini ki te wāhi noho o te waka, ā, ka tere ake te tukunga VOC i ngā pāmahana tiketike. I te wā e whakaranua ana me te werohanga, me tino whakahaere te wera kutikuti kia kore ai e pakaru te PP me te whakaputanga o ngā aldehydes me ngā ketones, kia mau ai te taumata kakara ≤ 3.0.

Te Roa Pupuri Muka Karāhe: Koinei te mea ngaro matua o ngā rauemi LGF. Me whakamahi ngā tīwiri kutikuti iti i te wā e hangaia ana te whakarewa werohanga kia mau tonu ai te roa o te muka karāhe i te wāhanga kua oti i waenga i te 3 mm me te 6 mm (ka rerekē ki te 0.2-0.4 mm mō ngā muka poto noa). Ki te kore, ka ngaro te painga o te whakakaha "muka karāhe roa".

III. Reriwe o te tuanui rā (Awaawa/Anga Waipuke): Te Whainga Tino Pai mō te Whakamāmā me te Tika o te Ahu

Whakaahuatanga o te Tauira Taupānga:

Ko ngā reera tuanui rā panoramic e horapa ana i te tuanui o te waka, e hiahia ana kia tino pakari, kia iti hoki te tauwehenga o te whakawhānui wera raina (CLTE). Ehara i te mea he taumaha noa ngā reera whakarewa tuku iho, engari me mahi hoki i ngā mahi tukatuka uaua, utu nui.

Otinga Rauemi: PP-GF50 (Teitei-Pakeke Matua)

Me te 50% o te muka karāhe, koinei te taumata "tuanui" mō te whakakaha PP, i hangaia mō ngā whakaritenga tino pakari.

Te Pakari e rite ana ki te Mea Whakarewa: Ko te PP-GF50 ka eke ki te taumata piko neke atu i te 10,000 MPa. Mā tēnei ka taea e ngā reera tuanui angiangi, angiangi te pupuri i te tika i raro i te huringa pāmahana, kia maeneene ai te paheke o te karāhe me te kore he haruru rerekē.

CLTE Iti: Ka ārai te hanganga whatunga o ngā muka karāhe roa i te whānui/whakaiti wera o te matihiko PP, ka whakaiti i tana CLTE mai i te 10-15×10⁻⁵/K mō te PP noa ki te 2-3×10⁻⁵/K (tata ki ngā taumata konumohe), ka whakaoti rapanga here rēri i puta mai i te whānui/whakaiti wera.

Akoranga Take me ngā Hua: I whakamahia e tētahi kaihanga waka Hainamana matua te PP-LGF50 hei whakakapi i ngā whakapuru konumohe mō ngā reera tuanui o tana SUV matua. Nā tēnei i whakaitihia te taumaha o ia wāhanga mā te 30%, ā, i whakauruhia hoki ngā whāriki whakarewa maha ki roto i te wāhanga i hangaia, i whakaitihia ai ngā taahiraa huihuinga mā te rima, ā, i tino whakaitihia ai ngā utu hanga katoa.

Ngā Whakaarohanga Whakaputa:

Te Puāwaitanga o te Muka Karāhe: Nā te nui o te muka o te GF50, he mea noa te "puāwaitanga o te muka karāhe" i runga i te mata o te wāhanga, ka pā ki te āhua. E taunakihia ana kia teitei te pāmahana pokepokea ai (80-100°C) me te hangarau tere wera/matao me ngā mata pokepokea ai kia kapi, kia mimiti rānei i ngā muka.

Ātete ki te Huarere: Ka pāngia ngā tuanui e te wai me te hihi UV. Me tāpiri he pango waro me ngā whakaū UV ki te hanganga hei ārai i te pirau o te rauemi me te kirikiri i raro i te hihi UV.—

IV. Whakarāpopototanga me te Tirohanga Ahumahi

Ehara i te mea he "kirihou" noa iho ngā rauemi muka karāhe roa PP, engari he "otinga rauemi hiato" matatini.

He momo whānui te PP-GF30, he pai mō ngā wāhanga huri noa i te mīhini (pērā i ngā taupoki) e hiahia ana kia taurite te ātete wera me te mahi whānui. Koinei hoki te kōwhiringa tuatahi mō ngā wāhanga hanganga o roto, e whakataurite ana i te pakari me te pakari, ā, ka taea te whakarerekē mō ngā turanga rīpene neke me ngā reera tuanui rā.

Ko te PP-GF40 te whiringa pai rawa atu mō te whakakapi i te nairona. Hei momo whānui kaha-waenga ki te-tiketike, ka hipokina e ia ngā wāhanga matua e toru, e whakataurite ana i te mahi me te utu. Ka tukuna e ia te mahi me te whai huatanga utu i roto i ngā wāhanga hanganga pēnei i ngā turanga rīpene neke.

He taputapu kaha a PP-GF50 mō te "whakakapi i te konganuku ki te kirihou," he mea motuhake ki ngā wāhanga hanganga nunui me ngā whakaritenga tino pakari, pērā i ngā reera tuanui me ngā kōwae pito-mua. I hangaia mō ngā tono wāhanga miihini kawenga-nui, he tino pakari, he ātete wera, he ātete ngoki, me te arotahi matua ki ngā taupoki miihini.

I te mea kei te huri haere te hiahia mō te whakamama i ngā waka mai i te "taunakitanga" ki te "whakahaunga," kei te whānui haere tonu ngā rohe tono o ngā rauemi PP muka karāhe roa i roto i ngā wāhanga hanganga waka.

Mēnā he hiahia whakatikatika ki te whakamāoritanga, ki te hōputu rānei, tena koa whakamōhio mai.
