Bulk Phenolic Fiberglass Molding Compound
Gabatarwar Samfuri
Babban sinadarin phenolic na gilashin fiber wani sinadari ne na thermosetting molding wanda aka yi da resin phenolic a matsayin kayan tushe, wanda aka ƙarfafa shi da zaruruwan gilashi, kuma an yi shi ta hanyar dasawa, haɗawa da sauran hanyoyin aiki. Yawancin lokaci yana haɗa da resin phenolic (mai ɗaurewa), zaren gilashi (kayan ƙarfafawa), cika ma'adinai da sauran ƙari (kamar mai hana harshen wuta, wakilin sakin mold, da sauransu).
Halayen Aiki
(1) Kyakkyawan halayen injiniya
Ƙarfin lanƙwasa mai girma: wasu samfura na iya kaiwa 790 MPa (wanda ya wuce ma'aunin ƙasa ≥ 450 MPa).
Juriyar Tasiri: ƙarfin tasiri mai ƙarfi ≥ 45 kJ/m², ya dace da sassan da ke ƙarƙashin nauyin aiki mai ƙarfi.
Juriyar Zafi: Zafin Martin mai jure zafi ≥ 280 ℃, kyakkyawan kwanciyar hankali a yanayin zafi mai yawa, ya dace da aikace-aikacen muhalli mai zafi mai yawa.
(2) Kayayyakin rufin lantarki
Juriyar saman: ≥1×10¹² Ω, juriyar girma ≥1×10¹⁰ Ω-m, don biyan buƙatun kariya mai yawa.
Juriyar baka: wasu samfura suna da lokacin juriyar baka ≥ daƙiƙa 180, wanda ya dace da abubuwan lantarki masu ƙarfin lantarki mai yawa.
(3) Juriyar tsatsa da kuma jinkirin harshen wuta
Juriyar Tsatsa: Yana jure danshi da mildew, wanda ya dace da yanayi mai zafi da danshi ko kuma mai lalata sinadarai.
Matsayin hana harshen wuta: wasu kayayyaki sun kai matakin UL94 V0, ba za a iya ƙonewa ba idan wuta ta tashi, ƙarancin hayaƙi kuma ba za a iya ƙonewa ba.
(4) Sarrafa daidaitawa
Hanyar ƙera: tallafawa ƙera allura, ƙera canja wuri, ƙera matsi da sauran hanyoyin aiki, waɗanda suka dace da abubuwan da suka shafi tsarin.
Ƙarancin raguwa: raguwar ƙira ≤ 0.15%, daidaitaccen ƙira mai girma, rage buƙatar bayan sarrafawa.
Sigogi na Fasaha
Ga wasu daga cikin sigogin fasaha na samfuran yau da kullun:
| Abu | Mai nuna alama |
| Yawan yawa (g/cm³) | 1.60~1.85 |
| Ƙarfin lanƙwasawa (MPa) | ≥130~790 |
| Juriyar Fuskar (Ω) | ≥1×10¹² |
| Ma'aunin asarar Dielectric (1MHz) | ≤0.03~0.04 |
| Shakar ruwa (mg) | ≤20 |
Aikace-aikace
- Masana'antar lantarki: Kera sassan kariya masu ƙarfi kamar harsashin mota, na'urorin haɗa abubuwa, na'urorin haɗa abubuwa, da sauransu.
- Masana'antar kera motoci: ana amfani da shi a sassan injin, sassan tsarin jiki, don inganta juriyar zafi da nauyi mai sauƙi.
- Sararin Samaniya: sassan gini masu jure zafi mai yawa, kamar sassan roka.
- Kayan lantarki da na lantarki: sassan kariya masu ƙarfin lantarki, gidajen canzawa, don biyan buƙatun hana ƙonewa da aikin lantarki.
Gargaɗi kan Sarrafawa da Ajiya
Tsarin latsawa: zafin jiki 150±5℃, matsin lamba 18-20Mpa, lokaci 1~1.5 min/mm.
Yanayin Ajiya: A kare daga haske da danshi, lokacin ajiya ≤ watanni 3, a gasa a zafin 90℃ na tsawon mintuna 2 ~ 4 bayan danshi.
