1. Izinto zokusetshenziswa
1.1 Impahla-Bakelite
Igama lekhemikhali lika-Bakelite yipulasitiki ye-phenolic, okuwuhlobo lokuqala lwepulasitiki oluzofakwa ekukhiqizweni kwezimboni.Inamandla amakhulu emishini, ukufakwa okuhle, ukumelana nokushisa nokumelana nokugqwala, ngakho-ke kuvame ukusetshenziselwa ukwenziwa kwezinto zikagesi, njengokushintshwa, izibambisi zezibani, izindlebe, ama-casing ocingo, ama-instrument casings, njll.Ukufika kwayo kubaluleke kakhulu ekuthuthukisweni kwezimboni.
1.2 Indlela ye-Bakelite
I-Phenolic ne-aldehyde compounds ingenziwa ibe yi-phenolic resin ngokusabela kwe-condensation ngaphansi kwesenzo se-acidic noma i-catalyst eyisisekelo.Hlanganisa i-phenolic resin ne-sawn wood powder, i-talcum powder (filler), i-urotropine (i-ejenti yokwelapha), i-stearic acid (i-lubricant), i-pigment, njll., nokushisa bese uxuba ku-mixer ukuze uthole impushana ye-Bakelite.I-bakelite powder iyashiswa futhi icindezelwe esikhunjeni ukuze ithole umkhiqizo wepulasitiki we-phenolic we-thermosetting.
2.Izici ze-bakelite
Izici ze-bakelite azikwazi ukumunca, azihambisani, ukumelana nokushisa okuphezulu namandla aphezulu.Ivame ukusetshenziswa ezintweni zikagesi, ngakho-ke ibizwa ngokuthi "i-bakelite".I-Bakelite yenziwe ngempuphu ye-phenolic resin, exutshwa ne-sawdust, i-asbestos noma i-Taoshi, bese icindezelwa ngaphandle kwesikhunta ekushiseni okuphezulu.Phakathi kwazo, i-phenolic resin iyi-resin yokuqala yokwenziwa emhlabeni.
Ipulasitiki ye-Phenolic (i-bakelite): ingaphezulu liqinile, liyaphuka futhi lintekenteke.Kuzwakala umsindo wezinkuni uma kungqongqoza.Ikakhulukazi i-opaque futhi imnyama (nsundu noma emnyama).Ayithambile emanzini ashisayo.Kuyi-insulator, futhi ingxenye yayo eyinhloko yi-phenolic resin.
