1. Imathiriyeli ekrwada
1.1 Izinto eziphathekayo-Bakelite
Igama lekhemikhali ye-Bakelite yiplastiki ye-phenolic, luhlobo lokuqala lweplastiki oluza kufakwa kwimveliso yoshishino.Inamandla amakhulu omatshini, ukugquma okulungileyo, ukuchasana nokushisa kunye nokumelana nokugqwala, ngoko isoloko isetyenziselwa ukuveliswa kwezinto zombane, ezifana nokutshintsha, izibane, ii-earphones, ii-casings zefowuni, ii-casings instrument casings, njl.Ukufika kwayo kubaluleke kakhulu kuphuhliso lwemizi-mveliso.
1.2 Indlela yeBakelite
Iikhompawundi ze-Phenolic kunye ne-aldehyde zingenziwa kwi-phenolic resin ngokuphendula kwe-condensation phantsi kwesenzo se-acidic okanye i-catalyst esisiseko.Xuba i-phenolic resin kunye ne-sawn wood powder, i-talcum powder (i-filler), i-urotropine (i-agent yokunyanga), i-stearic acid (i-lubricant), i-pigment, njl., kunye nobushushu kwaye udibanise kwi-mixer ukufumana i-Bakelite powder.I-bakelite powder ishushu kwaye icinezelwe kwi-mold ukufumana imveliso yeplastiki ye-phenolic ye-thermosetting.
2.Iimpawu ze-bakelite
Iimpawu ze-bakelite aziyi-absorbent, ayi-conductive, ukumelana nobushushu obuphezulu kunye namandla aphezulu.Ihlala isetyenziselwa izixhobo zombane, ngoko ibizwa ngokuba yi "bakelite".I-Bakelite yenziwe nge-powder phenolic resin, exutywe ne-sawdust, i-asbestos okanye i-Taoshi, kwaye icinezelwe ngaphandle kwi-mold kwiqondo lokushisa eliphezulu.Phakathi kwazo, i-phenolic resin yi-resin yokuqala yokwenziwa emhlabeni.
Iplastiki yePhenolic (i-bakelite): umphezulu unzima, ubhityile kwaye ubuthathaka.Kuvakala isandi sokhuni xa kunkqonkqozwa.Ikakhulu i-opaque kwaye imnyama (imdaka okanye emnyama).Ayithambile emanzini ashushu.Yi-insulator, kwaye inxalenye yayo ephambili yi-phenolic resin.
