Babban Haɗin Fiberglass Molding Compound
Gabatarwar Samfur
Bulk phenolic gilashin fiber gyare-gyare fili ne mai thermosetting gyare-gyaren fili sanya daga phenolic guduro a matsayin tushe abu, karfafa da gilashin zaruruwa, kuma sanya ta impregnation, hadawa da sauran matakai. Abubuwan da ke tattare da shi yawanci sun haɗa da guduro phenolic (binder), fiber gilashi (kayan ƙarfafawa), filler ma'adinai da sauran abubuwan ƙari (kamar ƙarancin wuta, wakili mai sakin mold, da sauransu).
Halayen Aiki
(1) Kyakkyawan kayan aikin injiniya
Ƙarfin lanƙwasawa: wasu samfurori na iya kaiwa 790 MPa (nisa fiye da ma'aunin ƙasa ≥ 450 MPa).
Ƙarfin tasiri: Ƙarfin tasiri mai mahimmanci ≥ 45 kJ/m², dace da sassan da ke ƙarƙashin nauyi mai ƙarfi.
Heat Juriya: Martin zafi-resistant zafin jiki ≥ 280 ℃, mai kyau girma da kwanciyar hankali a high yanayin zafi, dace da high-zazzabi muhalli aikace-aikace.
(2) Kayayyakin rufewar lantarki
Resistance surface: ≥1 × 10¹² Ω, juriya juriya ≥1 × 10¹⁰ Ω-m, don saduwa da babban rufi bukatun.
Juriya na Arc: wasu samfuran suna da lokacin juriya na baka ≥180 seconds, dace da manyan kayan aikin lantarki.
(3) Juriyar lalata da jinkirin wuta
Juriya na lalata: danshi da juriya na mildew, dace da yanayin zafi da zafi ko gurɓataccen yanayi.
Matsayi mai hana harshen wuta: wasu samfuran sun kai darajar UL94 V0, ba mai ƙonewa idan akwai wuta, ƙaramin hayaki da mara guba.
(4) Gudanar da daidaitawa
Hanyar gyare-gyare: goyon bayan gyare-gyaren allura, canja wurin gyare-gyare, matsawa gyare-gyare da sauran matakai, dace da hadaddun tsarin sassa.
Low shrinkage: gyare-gyare shrinkage ≤ 0.15%, high gyare-gyaren daidaici, rage bukatar post-aiki.
Ma'aunin Fasaha
Waɗannan su ne wasu sigogin fasaha na samfuran samfura:
| Abu | Mai nuna alama |
| Girma (g/cm³) | 1.60 ~ 1.85 |
| Ƙarfin lanƙwasawa (MPa) | ≥130 ~ 790 |

Aikace-aikace
- Masana'antar Electromechanical: Kera manyan sassa masu ƙarfi kamar su bawo, masu tuntuɓar juna, masu zirga-zirga, da sauransu.
- Masana'antar kera motoci: ana amfani da su a cikin sassan injin, sassan tsarin jiki, don haɓaka juriya na zafi da nauyi mai sauƙi.
- Jirgin sama: sassa na tsarin da ke jure zafin zafin jiki, kamar sassan roka.
- Kayan lantarki da na lantarki: sassa masu ɗaukar wutan lantarki mai ƙarfi, sauya gidaje, don biyan buƙatun mai hana wuta da aikin lantarki.
Tsare-tsare da Ajiyewa
Latsa tsari: zazzabi 150 ± 5 ℃, matsa lamba 18-20Mpa, lokaci 1 ~ 1.5 min / mm.
Yanayin ajiya: Kare daga haske da danshi, lokacin ajiya ≤ 3 watanni, gasa a 90 ℃ na 2 ~ 4 mintuna bayan danshi.
