Ma phenolic molding compounds ndi zinthu zopangira thermosetting zomwe zimapangidwa mwa kusakaniza, kukanda, ndi granulating phenolic resin ngati matrix yokhala ndi zodzaza (monga ufa wamatabwa, ulusi wagalasi, ndi ufa wa mchere), zophikira, mafuta, ndi zina zowonjezera. Ubwino wawo waukulu uli mu kukana kwawo kutentha kwambiri (kutentha kwanthawi yayitali mpaka 150-200℃), mphamvu zotetezera kutentha (kukana kwakukulu kwa voliyumu, kutayika kochepa kwa dielectric), mphamvu yamakina, ndi kukhazikika kwa magawo. Amakhalanso osagwirizana ndi dzimbiri la mankhwala, ali ndi ndalama zowongolera, ndipo amakhala ndi magwiridwe antchito okhazikika ngakhale kutentha kwambiri, magetsi ambiri, kapena chinyezi.

Mitundu yaMa Phenolic Molding Compounds 

Ma compounds Opangira Kupanikizika:Izi zimafuna kuponderezedwa. Zipangizozo zimayikidwa mu nkhungu kenako zimatsukidwa pansi pa kutentha kwakukulu ndi kupanikizika (nthawi zambiri 150-180℃ ndi 10-50MPa). Ndizoyenera kupanga mawonekedwe ovuta, kulondola kwakukulu, kapena zigawo zazikulu, zokhala ndi makoma okhuthala, monga zothandizira zotetezera kutentha mu zida zamagetsi ndi zida zotsutsana ndi kutentha mozungulira injini zamagalimoto. Ndi kufalikira kofanana kwa zodzaza, zinthuzi zimakhala ndi mphamvu yapamwamba kwambiri yamakina komanso kukana kutentha kwambiri, zomwe zimapangitsa kuti zigwiritsidwe ntchito kwambiri m'zigawo zamafakitale zapakati mpaka zapamwamba komanso mtundu wazinthu wamba.

Mankhwala opangira jakisoni:Zoyenera kugwiritsa ntchito popangira jekeseni, zinthuzi zimatha kuyenda bwino ndipo zimatha kudzazidwa mwachangu ndikuchiritsidwa mumakina opangira jekeseni, zomwe zimapangitsa kuti pakhale kupanga bwino komanso kudzipangira zokha. Ndizoyenera kupanga zinthu zazing'ono mpaka zapakati, zokhazikika bwino, monga ma switch panels a zida zapakhomo, zolumikizira zamagetsi zamagalimoto, ndi zida zazing'ono zamagetsi zotenthetsera. Chifukwa cha kufalikira kwa njira zopangira jekeseni komanso kukonza kuyenda bwino kwa zinthu, msika wa zinthuzi ukuwonjezeka pang'onopang'ono, makamaka pamene zikukwaniritsa zosowa zazikulu zopangira zinthu zamafakitale.

Madera Ogwiritsira NtchitoMa Phenolic Molding Compounds

Zipangizo Zamagetsi/Zamagetsi:Iyi ndi njira yofunika kwambiri yogwiritsira ntchito, yomwe ikuphatikizapo zinthu zotetezera kutentha ndi zida zomangira zida monga ma mota, ma transformer, ma circuit breaker, ndi ma relay, monga ma motor commutator, ma transformer insulation frames, ndi ma circuit breaker terminals. Kuteteza kutentha kwambiri komanso kukana kutentha kwambiri kwa zinthu zopanga phenolic molding kumatsimikizira kuti zida zamagetsi zimagwira ntchito bwino pansi pa mphamvu yamagetsi komanso kutentha kwambiri, zomwe zimateteza ma short circuit omwe amayamba chifukwa cha kulephera kwa insulation. Zinthu zopanga compression molding zimagwiritsidwa ntchito kwambiri pazinthu zofunika kwambiri zotetezera kutentha, pomwe zinthu zopanga jekeseni molding ndizoyenera kupanga zinthu zazing'ono zamagetsi.

Makampani Ogulitsa Magalimoto:Amagwiritsidwa ntchito pazinthu zosatentha m'mainjini a magalimoto, machitidwe amagetsi, ndi chassis, monga ma gasket a mutu wa silinda ya injini, nyumba zoyatsira moto, mabulaketi a sensor, ndi zida zama braking system. Zinthuzi zimafunika kupirira kutentha kwa injini kwa nthawi yayitali (120-180℃) ndi kugwedezeka. Ma phenolic molding compounds amakwaniritsa zofunikira izi chifukwa cha kukana kwawo kutentha kwambiri, kukana mafuta, ndi mphamvu yamakina. Ndi opepuka kuposa zipangizo zachitsulo, zomwe zimathandiza kuchepetsa kulemera ndi kugwiritsa ntchito bwino mafuta m'magalimoto. Ma compression molding compounds ndi oyenera pazinthu zosatentha kwambiri kuzungulira injini, pomwe ma injection molding compounds amagwiritsidwa ntchito pazinthu zamagetsi zazing'ono komanso zapakati.

Zipangizo Zapakhomo:Zoyenera kugwiritsidwa ntchito pazinthu zogwirira ntchito komanso zosatentha monga zophikira mpunga, ma uvuni, ma uvuni a microwave, ndi makina ochapira, monga zogwirizira mphika wamkati wa mpunga, zoyikapo zinthu zotenthetsera uvuni, zotchingira zitseko za uvuni wa microwave, ndi zophimba za makina ochapira. Zipangizo zogwirira ntchito ziyenera kupirira kutentha kwapakati mpaka kwakukulu (80-150℃) komanso chinyezi mukamagwiritsa ntchito tsiku lililonse.Mankhwala opangira phenolicamapereka ubwino waukulu pakukana kutentha kwambiri, kukana chinyezi, komanso mtengo wotsika. Majekeseni opangira jakisoni, chifukwa cha kupanga bwino kwambiri, akhala chisankho chachikulu mumakampani opanga zida zapakhomo.

Ntchito zina zikuphatikizapo zinthu monga ndege (monga zida zazing'ono zotetezera kutentha kwa zipangizo zoyendera m'mlengalenga), zipangizo zachipatala (monga zida zotetezera kutentha kwambiri), ndi ma valve a mafakitale (monga mipando yotsekera ma valve). Mwachitsanzo, ma treyi otsekera kutentha kwambiri m'zida zachipatala amafunika kupirira kuyeretsa kwa nthunzi ya 121°C, ndipo mankhwala opangidwa ndi phenolic amatha kukwaniritsa zofunikira pa kutentha ndi ukhondo; mipando yotsekera ma valve a mafakitale iyenera kukhala yolimba ku dzimbiri la media ndi kutentha kwina, zomwe zimasonyeza kuti imatha kusintha malinga ndi zochitika zosiyanasiyana.
