Phenolic molding mankhwala ndi thermosetting poumba zipangizo zopangidwa ndi kusakaniza, kukanda, ndi granulating phenolic utomoni monga matrix ndi fillers (monga nkhuni ulusi, galasi ulusi, ndi mchere ufa), machiritso agents, lubricant, ndi zina zowonjezera. Ubwino wawo waukulu wagona pakukana kwawo kutentha kwanthawi yayitali (kutentha kwanthawi yayitali mpaka 150-200 ℃), katundu wotchinjiriza (kuchuluka kwa mphamvu yamagetsi, kutsika kwa dielectric), mphamvu zamakina, komanso kukhazikika kwa mawonekedwe. Zimakhalanso zosagonjetsedwa ndi dzimbiri za mankhwala, zimakhala ndi ndalama zomwe zingathe kulamuliridwa, ndipo zimakhala zokhazikika ngakhale pansi pa kutentha kwambiri, kutentha kwakukulu, kapena malo a chinyezi.

Mitundu yaPhenolic Molding Compounds 

Compression Molding Compounds:Izi zimafuna compresses akamaumba. Zinthuzo zimayikidwa mu nkhungu kenako zimachiritsidwa ndi kutentha kwambiri komanso kupanikizika (nthawi zambiri 150-180 ℃ ndi 10-50MPa). Ndioyenera kupanga mawonekedwe ovuta, zofunikira zolondola kwambiri, kapena zigawo zazikulu, zokhuthala, monga zotetezera pazida zamagetsi ndi zinthu zosagwira kutentha mozungulira injini zamagalimoto. Ndi kubalalitsidwa yunifolomu yodzaza, zinthuzo zimawonetsa mphamvu zamakina apamwamba komanso kukana kutentha kwambiri, zomwe zimawapangitsa kuti azigwiritsidwa ntchito kwambiri m'mafakitale apakatikati mpaka apamwamba komanso mtundu wazinthu zachikhalidwe.

Mapangidwe a jekeseni:Zoyenera kupangira jekeseni, zidazi zimakhala ndi kutuluka kwabwino ndipo zimatha kudzazidwa mwachangu ndikuchiritsidwa mumakina opangira jakisoni, zomwe zimapangitsa kuti pakhale ntchito yabwino komanso yodzichitira yokha. Ndioyenera kupanga zinthu zambiri zazing'ono mpaka zapakatikati, zokhazikika mokhazikika, monga ma switch mapanelo a zida zapakhomo, zolumikizira zamagetsi zamagalimoto, ndi tizigawo tating'ono tamagetsi. Ndi kutchuka kwa njira zopangira jakisoni komanso kukhathamiritsa kwa zinthu zomwe zikuyenda bwino, gawo la msika wazinthuzi likuwonjezeka pang'onopang'ono, makamaka pamene akukumana ndi zofunikira zazikulu zopanga zinthu zamakampani ogula.

Magawo ofunsira aPhenolic Molding Compounds

Zida Zamagetsi/Zamagetsi:Uwu ndi mawonekedwe oyambira ogwiritsira ntchito, omwe amaphimba zida zotchingira ndi zida zamakina monga ma mota, ma transfoma, ma circuit breaker, ndi ma relay, monga ma commutators, mafelemu otsekereza ma transfoma, ndi ma terminal breaker. Kutsekemera kwapamwamba komanso kutentha kwapamwamba kwa mankhwala opangira phenolic kumapangitsa kuti zipangizo zamagetsi zizigwiritsidwa ntchito motetezeka pansi pa voteji komanso kutentha kwambiri, kuteteza maulendo afupipafupi omwe amayamba chifukwa cha kulephera kwazitsulo. Compression akamaumba mankhwala makamaka ntchito kwambiri kutchinjiriza zigawo zikuluzikulu, pamene jekeseni akamaumba mankhwala ndi oyenera kupanga misa ya tinthu tating'onoting'ono zamagetsi.

Makampani Agalimoto:Amagwiritsidwa ntchito pazinthu zolimbana ndi kutentha m'mainjini agalimoto, makina amagetsi, ndi ma chassis, monga ma gaskets a injini yama cylinder head, ma coil housings, mabulaketi a sensor, ndi zida zama braking system. Zidazi zimayenera kupirira kutentha kwa injini yayitali (120-180 ℃) ndi kugwedezeka kwamphamvu. Mankhwala opangira phenolic amakwaniritsa zofunikira izi chifukwa cha kukana kwawo kutentha kwambiri, kukana mafuta, komanso mphamvu zamakina. Amakhalanso opepuka kuposa zida zachitsulo, zomwe zimathandizira kuchepetsa kulemera komanso kuyendetsa bwino mafuta m'magalimoto. Compression akamaumba mankhwala ndi oyenera pakatikati kutentha zosagwira zigawo zikuluzikulu mozungulira injini, pamene jekeseni akamaumba mankhwala ntchito yaing'ono ndi sing'anga magetsi magetsi.

Zida Zapakhomo:Zoyenera pazida zosagwira kutentha komanso zogwira ntchito pazida monga zophika mpunga, mauvuni, mavuvuni a microwave, ndi makina ochapira, monga zopangira zamkati zamkati zophikira mpunga, zoyikapo zotenthetsera mu uvuni, zida zotchinjiriza zitseko za uvuni wa microwave, ndi zophimba zomaliza zamakina ochapira. Zida zamagetsi zimayenera kupirira kutentha kwapakati mpaka kumtunda (80-150 ℃) ndi malo achinyezi pakagwiritsidwe ntchito tsiku lililonse.Phenolic molding mankhwalaperekani zabwino zazikulu pakukana kutentha kwambiri, kukana chinyezi, komanso mtengo wotsika. Zopangira jekeseni, chifukwa chopanga bwino kwambiri, zakhala chisankho chachikulu pamakampani opanga zida zapakhomo.

Ntchito zina zikuphatikizapo zamlengalenga (monga zing'onozing'ono zotetezera zipangizo zoyendetsa ndege), zipangizo zachipatala (monga zigawo za kutentha kwambiri), ndi ma valve a mafakitale (monga mipando yosindikizira ma valve). Mwachitsanzo, ma trays otenthetsera kwambiri m'zida zamankhwala amayenera kupirira 121 ° C high-pressure steam sterilization, ndi ma phenolic molding compounds amatha kukwaniritsa zofunikira pakutentha ndi ukhondo; Mipando yosindikizira ma valve a mafakitale iyenera kugonjetsedwa ndi corrosion ya media ndi kutentha kwina, kuwonetsa kusinthika kwawo ku zochitika zingapo.
