Ukupakisha nokugcina
i-flake / powder: 20kg / isikhwama, 25kg / isikhwama, Ipakishwe esikhwameni esilukiweyo, noma esikhwameni sephepha se-Kraft esine-plastic liner ngaphakathi. I-resin kufanele igcinwe endaweni epholile, eyomile futhi engenamoya kahle kude nomthombo wokushisa ukuze kugwenywe umswakama kanye namakhekhe. Umbala wayo uzoba mnyama ngesikhathi sokugcina, okungeke kube nathonya ebangeni le-resin.
i-bakelite powder kanye ne-phenolic resin powder ehlukile.
Uyini umehluko phakathi kwe-phenolic resin powder ne-bakelite powder? Igama lekhemikhali le-bakelite yipulasitiki ye-phenolic, okuwuhlobo lokuqala lwamapulasitiki okufanele afakwe ekukhiqizweni kwezimboni. I-Phenolic resin ingalungiswa nge-polycondensation yama-phenols nama-aldehydes phambi kwama-catalysts ane-acidic noma alkaline. Impushana ye-Bakelite itholakala ngokuxuba ngokugcwele i-phenolic resin ne-sawn wood powder, i-talc powder (filler), i-urotropine (i-ejenti yokwelapha), i-stearic acid (i-lubricant), i-pigment, njll., kanye nokufudumeza nokuxuba ku-mixer. I-Bakelite powder yashiswa futhi yacindezelwa ekubunjweni ukuze kutholwe imikhiqizo yepulasitiki ye-phenolic ye-thermosetting.
I-Bakelite inamandla amakhulu okusebenza, i-insulation enhle, ukumelana nokushisa kanye nokumelana nokugqwala.ngakho-ke, ivamise ukusetshenziselwa ukwenza izinto zikagesi, njengamaswishi, izikepisi zamalambu, ama-headphone, amakesi ocingo, amabhokisi wezinsimbi, njll.“I-Bakelite” iqanjwe ngayo .
