Ipulasitiki ye-Phenolic, eyaziwa ngokuthi i-bakelite powder, yasungulwa ngo-1872 futhi yafakwa ekukhiqizeni izimboni ngo-1909. Ipulasitiki endala kunazo zonke emhlabeni, igama elijwayelekile lamapulasitiki asekelwe ku-phenolic resin, kanye nenye yepulasitiki ebaluleke kakhulu ye-thermosetting.Ngokujwayelekile, ingahlukaniswa ngamapulasitiki angewona aminated phenolic kanye namapulasitiki e-phenolic aminated.Amapulastiki e-phenolic angewona amlaminated angahlukaniswa abe amapulasitiki e-phenolic acindezelwe kanye namapulasitiki e-phenolic acindezelwe.Isetshenziswa kabanzi njengezinto zokufakelwa kukagesi, izingxenye zefenisha, izidingo zansuku zonke, imisebenzi yezandla, njengeigobolondo irayisi cooker, isibambo se-bakelite, shintsha izesekeli, njll. Ngaphezu kwalokho, kukhona amapulasitiki e-asbestos phenolic ikakhulukazi asetshenziselwa ukumelana ne-asidi, i-adhesive camera camera nendwangu yokwahlukanisa, ama-phenolic foam plastic kanye nama-honeycomb plastics for insulation thermal and sound insulation, njll.
I-Phenolic laminated plastic yenziwe nge-sheet filler efakwe nge-phenolic resin solution, engenziwa ibe amaphrofayili namapuleti ahlukahlukene.Ngokusho kwama-fillers ahlukene asetshenzisiwe, kukhona iphepha, indwangu, izinkuni, i-asbestos, indwangu yengilazi kanye namanye amapulasitiki alaminated.Indwangu yendwangu kanye nengilazi i-phenolic laminated plastics inezakhiwo ezinhle kakhulu zemishini, ukumelana nowoyela kanye nezakhiwo ezithile ze-dielectric.Asetshenziselwa ukwakha amagiya, amagobolondo athwalayo, amasondo aqondisayo, amagiya angathuli, amabherengi, izinto zikagesi zesakhiwo kanye nezinto zokufaka ugesi.Amapulasitiki anenziwe ngezinkuni afaneleka ama-bearings namagiya ngaphansi kokugcotshwa kwamanzi nokupholisa.Indwangu ye-asbestos eyenziwe ngepulasitiki elaminate isetshenziswa ikakhulukazi izingxenye ezisebenza ngaphansi kwezinga lokushisa eliphezulu.
Ipulasitiki yokucindezelwa okumise okwe-phenolic fiber ingashiswa futhi ibunjwe ibe izingxenye eziyinkimbinkimbi zemishini nezikagesi, ezinokufakwa okuhle kakhulu kukagesi, ukumelana nokushisa, ukumelana namanzi nokumelana nokugqoka.Ingenza ama-coil racks ahlukahlukene, ibhokisi lesiphetho, izindlu zamathuluzi kagesi, amaqabunga abalandeli, izixhumi zephampu ezingazweli acid, amagiya, amakhamera, njll.
