Tare da ci gaban da aka samu cikin sauri a masana'antar kera motoci ta "Sabbin Sabbin Zamani Huɗu" (Mai Sauƙi, Lantarki, Hankali), robobi na injiniya suna fuskantar sabbin dabarun aiki marasa misaltuwa. Daga cikin zaɓuɓɓuka da yawa fiye da ƙarfe, **PP mai tsawon fiber gilashi mai ƙarfi (PP-LGF)** ya zama zaɓi mafi kyau ga sassan tsarin mota da abubuwan da ke cikin aikin ciki, godiya ga kyakkyawan ƙarfinsa, juriyar gajiya, da kuma damar musamman ta "ƙarfe filastik."

A matsayin kamfani mai himma a wannan fanni, Jurong Best Composite Materials Co., Ltd. tana samar da jerin PP-GF30, PP-GF40, da PP-GF50, waɗanda suka cika dukkan buƙatun da ake buƙata tun daga tsarin ɗaukar kaya na biyu zuwa sassan kwarangwal masu ƙarfi. A ƙasa, mun zurfafa cikin takamaiman dabarun amfani da ƙimar waɗannan kayan a cikin manyan sassa uku: tushen lever ɗin juyawa, murfin injin, da kuma layin rufin rana.

I. Tushen Canjin Canji (Maƙallin Tsarin Gearshift): Daidaito Tsakanin Babban Tauri da Juriyar Rarrafe

Bayanin Yanayi na Aikace-aikace:

Tushen lever ɗin juyawa yana cikin yankin tsakiyar motar. Ba wai kawai yana ɗauke da ƙarfin juyawar direba ba, har ma yana tabbatar da tsarin sauyawar lantarki mai rikitarwa. Tushen ƙarfe na gargajiya suna da nauyi kuma suna iya fuskantar matsalolin NVH (Hayaniya, Girgiza, da Tauri).

Maganin Kayan Aiki: PP-GF40 (Rabon Zinare) Don wannan aikace-aikacen, PP-LGF tare da abun ciki na fiber gilashi 40% zaɓi ne mai araha.

Daidaita Aikin Inji: Idan aka kwatanta da PP-GF30, PP-GF40 yawanci yana samun ƙarfin lanƙwasa sama da 6000 MPa, wanda ke ba da juriya ga lalacewa. Wannan yana tabbatar da cewa a lokacin turawa da ja akai-akai, tushen ba ya rarrafe ko canzawa, yana kiyaye daidaitaccen yanayin motsi na inji.

Nazarin Shari'a & Sakamako: Wani babban kamfanin kera motoci na haɗin gwiwa ya canza tushe zuwa PP-GF40 a cikin haɓaka samfurin. Sakamakon ya nuna cewa a cikin gwaje-gwajen hawan zafi daga -35°C zuwa 85°C, PP-GF40 ba wai kawai ya kiyaye tauri kamar nailan ba har ma ya rage farashi da kusan 20-25%. Bugu da ƙari, ta amfani da ƙarancin yawan PP, ya sami raguwar nauyi na sassa ɗaya na sama da 15%.

Sharuɗɗan Samarwa:

Kula da Yaƙi: Tushen lever ɗin juyawa yana da tsari mai rikitarwa tare da ramuka da yawa da aka ɗora da kuma gano wuri. Duk da cewa PP-GF40 yana da sauƙin kwarara fiye da PA, ana buƙatar ƙirar ƙofa mai kyau (zai fi dacewa masu gudu a ƙofar bawul) don sarrafa yanayin zaren gilashi da kuma guje wa yaƙi da raguwar anisotropic ke haifarwa.

Ƙarfin Haɗi: Saboda ƙarancin polarity na PP, idan tushen yana buƙatar sukurori masu ɗauke da kaya, yana da kyau a tsara abubuwan da aka saka na ƙarfe ko amfani da walda ta ultrasonic don guje wa tsagewar damuwa da zaren sukurori mai danna kai tsaye ke haifarwa.

II. Murfin Inji (Murfin Shiga Mai Yawa / Murfin Kan Silinda): Yaƙin Jurewa a cikin "Turamin Tururi" Mai Zafi Mai Tsanani

Bayanin Yanayi na Aikace-aikace:

Murfin injin yana cikin yankin tsakiyar ɗakin injin, yana fuskantar iska mai zafi, tururin mai, da kuma yanayin zafi mai yawa (na dogon lokaci 120-140°C). Babban buƙatun sune juriyar tsufa na zafi na dogon lokaci da kwanciyar hankali na girma.

Maganin Kayan Aiki: PP-GF30 (Haɓaka Zafi Mai Daidaita)

Duk da cewa PP-GF30 wani nau'in kayan aiki ne da aka ƙarfafa musamman don amfani da shi, aikace-aikacen da ke kewaye da injin suna buƙatar gyara na musamman na daidaita tsufa da zafi (Heat Aging Stabilized).

Ƙarfin Gajiya Mai Yawan Zafi: A cikin tsarin PP na fiber na gilashi na yau da kullun, motsi na sarkar kwayoyin halitta yana ƙaruwa a yanayin zafi mai yawa, yana haifar da raguwar ƙarfi. Duk da haka, tsarin hanyar sadarwa mai girma uku wanda PP-GF30 mai dogon gilashi ya samar yana ba shi ƙarfin gajiya mai yawan zafin jiki a 120°C wanda ya ninka na PP na yau da kullun mai gajeren gilashi, har ma da kashi 10% sama da nailan mai ƙarfin gilashi, wanda aka san shi da juriyar zafi.

Nazarin Shari'a da Sakamako: Wani kamfanin kera motoci na Turai ya maye gurbin aluminum da PP-LGF30 don murfin ado na injin. Sakamakon ya kasance mai mahimmanci: bayan rage nauyi sama da kashi 40%, kayan LGF sun rage watsa girgizar injin mai yawan mita zuwa ɗakin. Ya wuce gwaje-gwajen tsufa na iska mai zafi na 150°C / awanni 1000 ba tare da fashewa ko lalacewa ba.

Sharuɗɗan Samarwa:

Ƙarancin Wari da Ƙarancin VOC: Murfin injin yana fuskantar sashin fasinja, kuma yanayin zafi mai yawa yana hanzarta fitar da iskar VOC. A lokacin haɗawa da ƙera allura, dole ne a sarrafa zafin yankewa sosai don guje wa lalacewar PP da samar da aldehydes da ketones, wanda ke tabbatar da ƙarancin ƙamshi ≤ 3.0.

Tsawon Rike Fiber na Gilashi: Wannan shine babban sirrin kayan LGF. Dole ne a yi amfani da sukurori masu ƙarancin yankewa yayin ƙera allura don tabbatar da cewa tsawon fiber na gilashi a cikin ɓangaren da aka gama ya kasance tsakanin mm 3 zuwa 6 mm (sabanin 0.2-0.4 mm ga zare na yau da kullun). In ba haka ba, fa'idar ƙarfafa "dogon fibre na gilashi" ta ɓace.

III. Layin Jirgin Ruwa na Rufin Rana (Tashar Magudanar Ruwa / Firam): Babban Binciken Sauƙi da Daidaito na Girma

Bayanin Yanayi na Aikace-aikace:

Layin rufin rana mai faɗi yawanci yana ratsa rufin abin hawa, yana buƙatar tauri mai yawa da ƙarancin ƙarfin faɗaɗa zafi (CLTE). Layin ƙarfe na gargajiya ba wai kawai yana da nauyi ba, har ma yana buƙatar matakai masu rikitarwa da tsada.

Maganin Kayan Aiki: PP-GF50 (Matsayin Babban Taurin Kai)

Tare da kashi 50% na fiber na gilashi, wannan shine matakin "rufi" don ƙarfafa PP, wanda aka tsara don buƙatun tauri mai tsanani.

Tauri Mai Kama da Karfe: PP-GF50 yawanci yana samun ƙarfin lanƙwasa sama da 10,000 MPa. Wannan yana ba da damar siraran layukan rufin rana masu sirara don kiyaye madaidaiciyar yanayi a lokacin zagayowar zafin jiki, yana tabbatar da zamewar gilashi mai santsi da rashin hayaniya mara kyau.

Ƙarancin CLTE: Tsarin hanyar sadarwa na dogon zare na gilashi yana takaita faɗaɗa/matsewar zafi na matrix na PP yadda ya kamata, yana rage CLTE ɗinsa daga 10-15 × 10⁻⁵/K ga PP na yau da kullun zuwa 2-3 × 10⁻⁵/K (kusa da matakan ƙarfe na aluminum), yana magance matsalolin ɗaure layin dogo da faɗaɗa/matsewar zafi ke haifarwa yadda ya kamata.

Nazarin Shari'a da Sakamako: Wani fitaccen kamfanin kera motoci na kasar Sin ya yi amfani da PP-LGF50 don maye gurbin bututun aluminum da aka yi amfani da su wajen fitar da sinadari mai rufi a saman rufin motar SUV ta farko. Wannan ya cimma raguwar nauyin kashi 30% a kowane bangare kuma ya hada maƙallan ƙarfe da yawa a cikin sashin da aka yi amfani da shi, wanda hakan ya rage matakan haɗawa da biyar kuma ya rage yawan farashin kera.

Sharuɗɗan Samarwa:

Fulawar Fiber na Gilashi: Tare da yawan sinadarin fiber na GF50, “fulawar fibre na gilashi” a saman ɓangaren abu ne da ya zama ruwan dare, wanda ke shafar bayyanarsa. Ana ba da shawarar yawan zafin mold (80-100°C) tare da fasahar kekuna mai sauri/sanyi da kuma saman mold mai laushi don rufe ko sha zare.

Juriyar Yanayi: Rufin rana yana fuskantar ruwa da hasken UV. Dole ne a ƙara abubuwan daidaita carbon da UV a cikin tsarin don hana lalacewa da kuma yin alli a ƙarƙashin hasken UV.—

IV. Takaitawa da Hasashen Masana'antu

Kayan zare na gilashi masu tsayi na PP ba wai kawai "robobi" ba ne, amma a maimakon haka, "maganin kayan haɗin gwiwa" ne masu rikitarwa.

PP-GF30 wani nau'in ma'auni ne na duniya baki ɗaya, wanda ya dace da abubuwan da ke kewaye da injin (kamar murfi) waɗanda ke buƙatar haɗin juriya ga zafi da aiki gabaɗaya. Hakanan shine zaɓi na farko don sassan tsarin ciki, daidaita ƙarfi da tauri, kuma ana iya daidaita shi don tushen lever na motsi da layukan rufin rana.

PP-GF40 shine mafi kyawun zaɓi don maye gurbin nailan. A matsayin ƙarfin matsakaici zuwa babban matakin duniya, yana rufe dukkan manyan sassa uku, yana daidaita aiki da farashi. Yana ba da aiki da ingantaccen farashi a sassan gini kamar tushen lever na canzawa.

PP-GF50 kayan aiki ne mai ƙarfi don "maye gurbin ƙarfe da filastik," wanda ya ƙware a manyan sassan gini waɗanda ke da buƙatar tauri mai yawa, kamar layin rufin rana da na'urori na gaba. An ƙera shi don aikace-aikacen ɗakunan injin masu ɗaukar nauyi, yana ba da tauri mai yawa, juriya ga zafi, da juriya ga rarrafe, tare da mayar da hankali kan murfin injin.

Ganin cewa buƙatar sauya kayan rage nauyi na mota daga "shawarwari" zuwa "wajibi," iyakokin aikace-aikacen kayan PP masu dogon gilashi a cikin sassan tsarin mota suna ci gaba da faɗaɗawa.

Ku sanar da ni idan kuna buƙatar wasu gyare-gyare ga fassarar ko tsarin.
