Bulk Phenolic Fiberglass Molding Compound
Chiyambi cha Zamalonda
Chochuluka phenolic galasi CHIKWANGWANI akamaumba pawiri ndi thermosetting akamaumba pawiri wopangidwa ndi phenolic utomoni monga zinthu m'munsi, analimbitsa ndi ulusi galasi, ndipo opangidwa ndi impregnation, kusakaniza ndi njira zina. Kapangidwe kake kamakhala ndi phenolic resin (binder), ulusi wagalasi (zowonjezera), mineral filler ndi zina zowonjezera (monga retardant lawi, chotulutsa nkhungu, ndi zina).
Makhalidwe Antchito
(1) Makina abwino kwambiri
Mphamvu yopindika kwambiri: zinthu zina zimatha kufikira 790 MPa (kuposa muyezo wadziko lonse ≥ 450 MPa).
Kukana kwamphamvu: Notched mphamvu yamphamvu ≥ 45 kJ/m², yoyenera magawo omwe ali ndi katundu wosunthika.
Kutentha kwa kutentha: Martin kutentha kosagwira kutentha ≥ 280 ℃, kukhazikika kwabwino pa kutentha kwakukulu, koyenera kugwiritsa ntchito chilengedwe cha kutentha kwambiri.
(2) Mphamvu zotchingira magetsi
Kulimbana kwapamtunda: ≥1×10¹² Ω, kusinthasintha kwa voliyumu ≥1×10¹⁰ Ω-m, kukwaniritsa zosowa zazikulu zotchinjiriza.
Kukaniza kwa Arc: zinthu zina zimakhala ndi nthawi ya arc resistance ≥180 masekondi, oyenera zida zamagetsi zamphamvu kwambiri.
(3) Kulimbana ndi dzimbiri komanso kuchedwa kwamoto
Kukana kwa dzimbiri: kugonjetsedwa ndi chinyezi ndi mildew, koyenera kumadera otentha komanso onyowa kapena owononga mankhwala.
Gulu loletsa moto: zinthu zina zafika kalasi ya UL94 V0, zosayaka ngati moto, utsi wochepa komanso wopanda poizoni.
(4) Kusintha kusinthasintha
Kuumba njira: kuthandizira jekeseni akamaumba, kusamutsa akamaumba, psinjika akamaumba ndi njira zina, oyenera zigawo zikuluzikulu structural.
Kuchepa kwapang'onopang'ono: shrinkage ≤ 0.15%, kuwongolera kwakukulu, kuchepetsa kufunikira kwa post-processing.
Magawo aukadaulo
Zotsatirazi ndi zina mwaukadaulo wazinthu zamtundu uliwonse:
| Kanthu | Chizindikiro |
| Kachulukidwe (g/cm³) | 1.60-1.85 |
| Mphamvu yopindika (MPa) | ≥130~790 |
| Kukaniza Pamwamba (Ω) | ≥1 × 10¹² |
| Dielectric loss factor (1MHz) | ≤0.03~0.04 |
| Kumwa madzi (mg) | ≤20 |
Mapulogalamu
- Makampani a Electromechanical: Kupanga zida zotchingira zolimba kwambiri monga zipolopolo zamagalimoto, zolumikizira, zoyendera, ndi zina zambiri.
- Makampani opanga magalimoto: amagwiritsidwa ntchito m'magawo a injini, mawonekedwe a thupi, kukonza kukana kutentha ndi kulemera kopepuka.
- Azamlengalenga: Zigawo zomangika zolimbana ndi kutentha kwambiri, monga zida za roketi.
- Zipangizo zamagetsi ndi zamagetsi: zida zotchingira zokwera kwambiri, zosinthira nyumba, kuti zikwaniritse zofunikira zoletsa moto komanso magetsi.
Kusamala Pokonza ndi Kusungirako
Kukanikiza ndondomeko: kutentha 150 ± 5 ℃, kuthamanga 18-20Mpa, nthawi 1 ~ 1.5 min / mm.
Kusungirako: Tetezani ku kuwala ndi chinyezi, nthawi yosungirako ≤ miyezi 3, kuphika pa 90 ℃ kwa 2 ~ 4 mphindi pambuyo pa chinyezi.
