Mankhwala opangira phenolicZigawidwa m'magulu awiri kutengera kusiyana kwa njira zopangira:

Ma Compound Opangira Ma Compression: Amakonzedwa kudzera mu compression molding, pomwe zinthu zimayikidwa mu nkhungu ndikutenthedwa ndi kutentha kwambiri (nthawi zambiri 150-180°C, 10-50 MPa) kuti zitheke kuchira. Zoyenera kupanga mawonekedwe ovuta, zigawo zomwe zimafuna kulondola kwakukulu, kapena zigawo zazikulu zokhala ndi makoma okhuthala monga mabulaketi oteteza mu zida zamagetsi ndi zigawo zosagwirizana ndi kutentha mozungulira injini zamagalimoto. Ndi kufalikira kofanana kwa filler, izi zimapereka mphamvu yapamwamba kwambiri yamakina komanso kukana kutentha kwambiri. Amagwiritsidwa ntchito kwambiri m'zigawo zamafakitale zapakati mpaka zapamwamba ndipo amayimira mtundu wazinthu wamba.

Ma Injection Moulding Compounds: Opangidwa kuti azigwiritsidwa ntchito popanga ma injection molding, zipangizozi zimakhala ndi mphamvu zabwino kwambiri zoyendera. Zimadzaza ma injection mwachangu ndikuchiritsa pogwiritsa ntchito makina opangira ma injection, zomwe zimapangitsa kuti pakhale kupanga bwino komanso kudzipangira zokha. Zabwino kwambiri popanga zinthu zazing'ono mpaka zapakati zomwe zimakhala ndi kapangidwe kofanana, monga ma switch panels a zida zapakhomo, zolumikizira zamagetsi zamagalimoto, ndi zotchingira zamagetsi zazing'ono. Chifukwa cha kugwiritsa ntchito ma injection molding komanso kuyenda bwino kwa zinthu, msika wa gulu la zinthuzi ukuwonjezeka pang'onopang'ono, makamaka kukwaniritsa zosowa zazikulu za zinthu zamafakitale.

Ma Domain a Ntchito: Zochitika Zoyambira zaMa Phenolic Molding Compounds

Kugwiritsa ntchito mankhwala opangira phenolic kumayendetsedwa kwambiri popanga mafakitale, ndipo kumagawidwa m'magawo anayi osiyana:

Zipangizo Zamagetsi/Zamagetsi: Gawo lofunikira kwambiri limaphatikizapo zinthu zotetezera kutentha ndi zomangamanga zama mota, ma transformer, ma circuit breaker, ma relay, ndi zida zina zofanana. Zitsanzo zikuphatikizapo ma motor commutator, ma transformer insulating cores, ndi ma terminals a circuit breaker. Mapulasitiki opangidwa ndi phenolic molded insulation komanso kukana kutentha kumatsimikizira kuti zipangizo zamagetsi zikugwira ntchito bwino pansi pa mphamvu yamagetsi komanso kutentha kwambiri, zomwe zimaletsa ma short circuit omwe amayamba chifukwa cha kulephera kwa insulation. Mapulasitiki opangidwa ndi compression molded amagwiritsidwa ntchito makamaka pazinthu zofunika kwambiri zotetezera kutentha, pomwe mapulasitiki opangidwa ndi jakisoni amayenerera kupanga zinthu zazing'ono zamagetsi.

Makampani Ogulitsa Magalimoto: Amagwiritsidwa ntchito m'zigawo zosatentha pazida zamagetsi zamagalimoto, makina amagetsi, ndi chassis, monga ma gasket a mutu wa silinda ya injini, ma ignition coil housings, ma sensor brackets, ndi zigawo za brake system. Zigawozi ziyenera kupirira kutentha kwa injini kwa nthawi yayitali (120-180°C) ndi kugwedezeka/kukhudzidwa. Mapulasitiki opangidwa ndi phenolic amakwaniritsa zofunikira chifukwa cha kukana kwawo kutentha kwambiri, kukana mafuta, ndi mphamvu yamakina, pomwe amapereka kulemera kopepuka kuposa zitsulo kuti achepetse kulemera kwa galimoto ndi kugwiritsa ntchito mafuta. Mapulasitiki opangidwa ndi compression amayenerera zigawo za injini zosatentha kwambiri, pomwe mapulasitiki opangidwa ndi jakisoni amagwiritsidwa ntchito pazinthu zamagetsi zazing'ono mpaka zapakati.

Zipangizo Zapakhomo: Zoyenera kugwiritsidwa ntchito popanga zinthu zogwirira ntchito komanso zogwira ntchito bwino monga zophikira mpunga, ma uvuni amagetsi, ma microwave, ndi makina ochapira. Zitsanzo zikuphatikizapo mabulaketi amkati mwa mphika wa mpunga, zomangira zotenthetsera uvuni zamagetsi, zida zotenthetsera zitseko za microwave, ndi zipewa za makina ochapira. Zipangizozi ziyenera kupirira kutentha pang'ono mpaka kwakukulu (80-150°C) komanso malo onyowa nthawi zonse. Mapulasitiki opangidwa ndi phenolic amapereka ubwino waukulu pakukana kutentha kwambiri, kukana chinyezi, komanso kugwiritsa ntchito ndalama zochepa. Mapulasitiki opangidwa ndi jakisoni, chifukwa cha kupanga kwawo bwino, akhala chisankho chachikulu m'gulu la zida zapakhomo.

Ntchito Zina:Mapulasitiki opangidwa ndi phenolicamagwiritsidwanso ntchito mumlengalenga (monga zida zazing'ono zotetezera kutentha kwa zida zomwe zili m'bwato), zida zachipatala (monga zida zoyeretsera kutentha kwambiri), ndi ma valve a mafakitale (monga mipando yotsekera ma valve). Mwachitsanzo, ma treyi oyeretsera kutentha kwambiri m'zida zachipatala ayenera kupirira kuyeretsa kwa nthunzi ya 121°C, komwe mapulasitiki opangidwa ndi phenolic amakwaniritsa zofunikira zonse ziwiri kukana kutentha komanso ukhondo. Zisindikizo za mipando ya ma valve a mafakitale zimafuna kukana dzimbiri la media ndi kutentha kwina, zomwe zimasonyeza kuti zimatha kusinthasintha pa ntchito zosiyanasiyana.
