Ukupakisha kunye nokugcinwa
iflake / umgubo: 20kg / ibhegi, 25kg / ibhegi, Ipakishwe kwibhegi elukiweyo, okanye kwingxowa yephepha yeKraft eneplastiki ngaphakathi. I-resin kufuneka igcinwe kwindawo epholileyo, eyomileyo kwaye engenamoya kakuhle kude nomthombo wobushushu ukunqanda ukufuma kunye nokuqhaqha. Umbala wayo uya kuba mnyama kunye nexesha lokugcina, elingayi kuba nempembelelo kwibakala le-resin.
i-bakelite powder kunye ne-phenolic resin powder eyahlukileyo.
Uthini umahluko phakathi kwe-phenolic resin powder kunye ne-bakelite powder? Igama lekhemikhali ye-bakelite yiplastiki ye-phenolic, luhlobo lokuqala lweeplastiki eziza kufakwa kwimveliso yoshishino. I-Phenolic resin inokulungiswa nge-polycondensation ye-phenols kunye ne-aldehydes phambi kwe-acidic okanye i-alkaline catalysts. I-Bakelite powder ifunyenwe ngokuxuba ngokupheleleyo i-phenolic resin kunye ne-sawn wood powder, i-talc powder (i-filler), i-urotropine (i-agent yokunyanga), i-stearic acid (i-lubricant), i-pigment, njl., kunye nokufudumeza kunye nokuxuba kwi-mixer. I-Bakelite powder yayishushu kwaye icinezelwe kwi-mold ukufumana iimveliso zeplastiki ze-phenolic ze-thermosetting.
I-Bakelite inamandla amakhulu omatshini, ukugquma okulungileyo, ukuxhathisa ubushushu kunye nokumelana nokukhula.ngoko, isetyenziselwa ukwenza izinto zombane, ezifana nokutshintsha, izibane zesibane, ii-headphones, iifowuni zefowuni, izixhobo zesixhobo, njl. .
