Iyini i-Polytetrafluoroethylene Micro Powder?
I-Polytetrafluoroethylene Micro Powder, eyaziwa nangokuthi isisindo esiphansi se-polytetrafluoroethylene i-micro powder, i-polytetrafluoroethylene ultrafine powder, ne-polytetrafluoroethylene wax, iyi-resin emhlophe eyimpuphu etholwe yi-polymerization ye-tetrafluoroethylene oketshezini oluhlakazekile, oluhlakazekile, lukhiqize uketshezi oluhlakazekile nolomile. isisindo-free-flowing powder.
Isingeniso
I-Polytetrafluoroethylene micropowder, eyaziwa nangokuthi isisindo esiphansi se-molecular polytetrafluoroethylene micro powder noma i-polytetrafluoroethylene ultrafine powder noma i-polytetrafluoroethylene wax, iyi-resin emhlophe eyimpuphu etholwe yi-polymerization ye-tetrafluoroethylene oketshezini oluhlakazekile, i-washing, iwashi. Inezici ezinhle kakhulu ezifana nokumelana nokushisa, ukumelana nesimo sezulu, ukumelana nokubanda, ukungqubuzana okuphansi, ukunganamatheli, ukuqina kwamakhemikhali, kanye nokufakwa kukagesi. Ukwengeza, ngenxa yobuncane bezinhlayiyana ezimaphakathi, inokuhlakazeka okuhle futhi kulula ukuyihlanganisa ngokufana nezinye izinto. I-Polytetrafluoroethylene (PTFE) I-ultrafine micro powder iyimpushana emhlophe ephansi enesisindo esingagelezi kahle enesakhiwo samangqamuzana esizinzile esihlanganisa -(-CF2-CF2-)n, enokumelana okuhle kakhulu kwamakhemikhali, ukuzinza okushisayo, ukumelana nesimo sezulu esiphezulu (iminyaka engaphezu kweshumi), UV ukumelana, ukumelana nezinga lokushisa eliphezulu (izinga lokushisa lesikhathi eside lesicelo lizungeze ama-260°C), izinga lokushisa elibanzi (-200 kuya ku-260°C), izakhiwo ezinhle ezingezona izinduku, ukufakwa kukagesi okuphezulu (1017Ωcm), ukubambezeleka komlilo okuphezulu, nokuhle kakhulu. izinto zokuzithambisa.
Izakhiwo ezihlukile
PTFE i-micro powder imikhiqizo inokuhlanzeka kwe-100%, isisindo samangqamuzana esingaphansi kuka-10,000, kanye nosayizi wezinhlayiyana ebangeni lika-0.5-15μm. Abagcini nje ngokugcina zonke izici ezinhle kakhulu ze-polytetrafluoroethylene kodwa futhi banezici eziningi eziyingqayizivele, njengokungabikho kwe-self-agglomeration, akukho mphumela kagesi omile, ukuncibilika okuhle, isisindo esiphansi samangqamuzana, i-dispersibility enhle, i-self-lubrication, kanye nokunciphisa okukhulu kwe-friction coefficient. .
Izicelo zePolytetrafluoroethylene Micro Powder
I-Polytetrafluoroethylene micropowder ingasetshenziswa njengesithambiso esiqinile sodwa noma njengesithasiselo samapulasitiki, irabha, okokunamathela, oyinki, amafutha okugcoba, namafutha. Uma ixubene namapulasitiki noma irabha, izindlela ezehlukene ezijwayelekile zokucubungula impushana ezinjengokuxuba zingasetshenziswa, kanti inani elingeziwe lingu-5-20%. Ukwengeza i-polytetrafluoroethylene impushana encane kuwoyela namafutha kunganciphisa i-coefficient yokungqubuzana, futhi amaphesenti ambalwa nje angandisa impilo yamafutha okugcoba. I-organic solvent dispersion yayo ingasetshenziswa futhi njenge-ejenti yokukhulula.
