Chopangira Chopangira Fiberglass Chochuluka cha Phenolic
Chiyambi cha Zamalonda
Chomera cha ulusi wagalasi cha phenolic ndi chomera cha thermosetting chomwe chimapangidwa ndi phenolic resin ngati maziko, cholimbikitsidwa ndi ulusi wagalasi, ndipo chimapangidwa ndi impregnation, kusakaniza ndi njira zina. Kapangidwe kake nthawi zambiri kamakhala ndi phenolic resin (binder), ulusi wagalasi (zinthu zolimbitsa), mineral filler ndi zina zowonjezera (monga choletsa moto, chotulutsa nkhungu, ndi zina zotero).
Makhalidwe Ogwira Ntchito
(1) Kapangidwe kabwino kwambiri ka makina
Mphamvu yopindika kwambiri: zinthu zina zimatha kufika 790 MPa (yoposa muyezo wa dziko lonse ≥ 450 MPa).
Kukana kugwedezeka: mphamvu ya kugwedezeka yodulidwa ≥ 45 kJ/m², yoyenera ziwalo zomwe zimayang'aniridwa ndi mphamvu zamagetsi.
Kukana kutentha: Kukana kutentha kwa Martin ≥ 280 ℃, kukhazikika bwino pa kutentha kwambiri, koyenera kugwiritsidwa ntchito pa kutentha kwambiri.
(2) Kapangidwe ka magetsi koteteza kutentha
Kukana pamwamba: ≥1×10¹² Ω, kukana kwa voliyumu ≥1×10¹⁰ Ω-m, kuti zikwaniritse zosowa zambiri zotetezera kutentha.
Kukana kwa Arc: zinthu zina zimakhala ndi nthawi yokana arc ≥masekondi 180, zoyenera zida zamagetsi zamagetsi amphamvu kwambiri.
(3) Kukana dzimbiri ndi kuchedwa kwa moto
Kukana dzimbiri: Kukana chinyezi ndi bowa, koyenera malo otentha komanso onyowa kapena owononga mankhwala.
Mtundu woletsa moto: zinthu zina zafika pamtundu wa UL94 V0, sizingayaka ngati moto wayaka, utsi wochepa komanso sizili ndi poizoni.
(4) Kusinthasintha kwa ntchito
Njira yopangira: kuthandizira kupanga jakisoni, kusamutsa kupanga, kupanga kuponderezana ndi njira zina, zoyenera zigawo zovuta za kapangidwe kake.
Kuchepa kwa kuumba: kuchepa kwa kuumba ≤ 0.15%, kulondola kwambiri kwa kuumba, kuchepetsa kufunikira kokonza pambuyo pake.
Magawo aukadaulo
Izi ndi zina mwa zinthu zaukadaulo zomwe zimagwiritsidwa ntchito pazinthu wamba:
| Chinthu | Chizindikiro |
| Kuchulukana (g/cm³) | 1.60~1.85 |
| Mphamvu yopindika (MPa) | ≥130~790 |
| Kusakhazikika Pamwamba (Ω) | ≥1×10¹² |
| Dielectric loss factor (1MHz) | ≤0.03~0.04 |
| Kuyamwa madzi (mg) | ≤20 |
Mapulogalamu
- Makampani opanga zamagetsi: Kupanga zida zotetezera kutentha kwambiri monga zipolopolo zamagalimoto, zolumikizira, zoyendera, ndi zina zotero.
- Makampani opanga magalimoto: amagwiritsidwa ntchito m'zigawo za injini, ziwalo za kapangidwe ka thupi, kuti awonjezere kukana kutentha ndi kulemera kopepuka.
- Ndege: zigawo za kapangidwe kake zomwe sizimatentha kwambiri, monga zigawo za roketi.
- Zipangizo zamagetsi ndi zamagetsi: zida zotetezera kutentha kwambiri, nyumba yosinthira, kuti zikwaniritse zofunikira za kuletsa moto ndi magwiridwe antchito amagetsi.
Njira Zotetezera Kukonza ndi Kusunga
Njira yokanikiza: kutentha 150±5℃, kupanikizika 18-20Mpa, nthawi 1~1.5 min/mm.
Mkhalidwe Wosungira: Tetezani ku kuwala ndi chinyezi, nthawi yosungira ≤ miyezi itatu, kuphika pa 90℃ kwa mphindi 2-4 mutatha chinyezi.
