Tekinoloje yopanga ndi njira ya bakelite

1. Zopangira
1.1 Zinthu za Bakelite
Dzina la mankhwala a Bakelite ndi pulasitiki ya phenolic, yomwe ndi mtundu woyamba wa pulasitiki kuyikidwa m'makampani opanga mafakitale.Lili ndi mphamvu zamakina apamwamba, kutsekemera kwabwino, kukana kutentha ndi kukana kwa dzimbiri, choncho nthawi zambiri amagwiritsidwa ntchito popanga zipangizo zamagetsi, monga ma switch, nyali, makutu, ma casings a telefoni, zida za zida, ndi zina zotero.Kubwera kwake kuli ndi tanthauzo lalikulu pakukula kwa mafakitale.
1.2 Njira ya Bakelite
Phenolic ndi aldehyde mankhwala akhoza kukhala phenolic utomoni ndi condensation anachita pansi pa zochita za acidic kapena maziko chothandizira.Sakanizani utomoni wa phenolic ndi ufa wamatabwa wocheka, talcum powder (filler), urotropine (ochiritsa), stearic acid (lubricant), pigment, etc., ndi kutentha ndi kusakaniza mu chosakanizira kuti mupeze ufa wa Bakelite.Ufa wa bakelite umatenthedwa ndikukanikizidwa mu nkhungu kuti upeze mankhwala apulasitiki a thermosetting phenolic.

2.Makhalidwe a bakelite
Makhalidwe a bakelite ndi osayamwitsa, osayendetsa, kukana kutentha kwambiri komanso mphamvu zambiri.Nthawi zambiri amagwiritsidwa ntchito pazida zamagetsi, motero amatchedwa "bakelite".Bakelite amapangidwa ndi ufa wa phenolic resin, womwe umasakanizidwa ndi utuchi, asibesitosi kapena Taoshi, kenako ndikukankhira mu nkhungu kutentha kwambiri.Pakati pawo, phenolic resin ndiye utomoni woyamba padziko lapansi.
Phenolic pulasitiki (bakelite): pamwamba ndi olimba, Chimaona ndi osalimba.Pamamveka phokoso la nkhuni pogogoda.Nthawi zambiri imakhala yowoneka bwino komanso yakuda (yofiirira kapena yakuda).Sichifewa m'madzi otentha.Ndi insulator, ndipo chigawo chake chachikulu ndi phenolic resin.
