1. Raw materials
1.1 Material-Bakelite
Bakelite's chemical name is phenolic plastic, inova ndiyo yekutanga mhando yepurasitiki kuiswa mukugadzirwa kwemaindasitiri.Iine simba rakakwirira remagetsi, kunaka kwekudzivirira, kupisa kwekushisa uye kusagadzikana kwehutu, saka inowanzoshandiswa mukugadzirwa kwezvinhu zvemagetsi, zvakadai sema switch, mwenje, maearphone, casings foni, simbi casings, nezvimwewo.Kuuya kwayo kwakakosha zvikuru mukusimudzira maindasitiri.
1.2 Bakelite nzira
Phenolic uye aldehyde makomisheni anogona kugadzirwa kuita phenolic resin ne condensation reaction pasi pekuita kwe acidic kana basic catalyst.Sanganisa phenolic resin nesawn huni hupfu, talcum hupfu (filler), urotropine (curing agent), stearic acid (lubricant), pigment, nezvimwewo, uye kupisa uye sanganisa mumixer kuti uwane hupfu hweBakelite.Iyo bakelite poda inopisa uye inotsikirirwa muforoma kuti iwane thermosetting phenolic plastic product.
2.Zvinhu zvebhakelite
Hunhu hwebakelite hahuna kunyura, husina-conductive, kukwirira kwekushisa kwekudzivirira uye simba rakawanda.Inowanzoshandiswa mumidziyo yemagetsi, saka inonzi "bakelite".Bakelite inogadzirwa nehupfu phenolic resin, iyo yakasanganiswa nesawdust, asbestos kana Taoshi, uye yobva yatsindirwa kunze muforoma pane tembiricha.Pakati pavo, phenolic resin ndiyo yekutanga resin yekugadzira munyika.
Phenolic plastiki (bakelite): pasi yakaoma, brittle uye isina kusimba.Pane ruzha rwehuni pakugogodza.Iyo yakawanda opaque uye yakasviba (brown kana dema).Haina kupfava mumvura inopisa.Iyo insulator, uye chikamu chayo chikuru phenolic resin.
