Kulongedza ndi kusunga
flake / ufa: 20kg / thumba, 25kg / thumba, ankanyamula mu thumba nsalu, kapena Kraft pepala thumba ndi pulasitiki liner mkati. Utoto uyenera kusungidwa pamalo ozizira, owuma komanso olowera mpweya wabwino kutali ndi gwero la kutentha kupewetsa chinyontho ndi kufota. Mtundu wake udzakhala wakuda ndi nthawi yosungira, zomwe sizingakhudze kalasi ya utomoni.
bakelite ufa ndi phenolic utomoni ufa osiyana.
Kodi pali kusiyana kotani pakati pa phenolic resin powder ndi bakelite powder? Dzina la mankhwala a bakelite ndi pulasitiki ya phenolic, yomwe ndi mitundu yoyamba ya mapulasitiki omwe amapangidwa m'mafakitale. Phenolic resin ikhoza kukonzedwa ndi polycondensation ya phenols ndi aldehydes pamaso pa acidic kapena zamchere catalysts. Bakelite ufa umapezeka posakaniza bwino phenolic resin ndi macheka nkhuni ufa, talc ufa (filler), urotropine (mankhwala wothandizila), stearic acid (lubricant), pigment, etc., ndi kutentha ndi kusakaniza mu chosakanizira. ufa wa Bakelite udatenthedwa ndikuunikizidwa mu nkhungu kuti upeze mankhwala apulasitiki a thermosetting phenolic.
Bakelite ali ndi mphamvu zamakina apamwamba, kutchinjiriza kwabwino, kukana kutentha komanso kukana dzimbiri.chifukwa chake, nthawi zambiri amagwiritsidwa ntchito popanga zida zamagetsi, monga masiwichi, zisoti za nyali, zomverera m'makutu, makaseti amafoni, ma casings a zida, etc. "Bakelite" amatchulidwa pambuyo pake. .
