Yintoni iPolytetrafluoroethylene Micro Powder?
IPolytetrafluoroethylene Micro Powder, ekwaziwa ngokuba yi-polytetrafluoroethylene micro powder, i-polytetrafluoroethylene ultrafine powder, kunye ne-polytetrafluoroethylene wax, yiresin emhlophe engumgubo efunyenwe yipolymerization ye-tetrafluoroethylene kulwelo olusasaziweyo kunye nokusabalalisa ulwelo oluphantsi, ukuvelisa ulwelo olusasaziweyo kunye nolomileyo. ubunzima obungaguqukiyo umgubo.
intshayelelo
I-Polytetrafluoroethylene micropowder, eyaziwa ngokuba yi-low molecular weight polytetrafluoroethylene micro powder okanye i-polytetrafluoroethylene ultrafine powder okanye i-polytetrafluoroethylene wax, i-resin emhlophe engumgubo efunyenwe yi-polymerization ye-tetrafluoroethylene kulwelo olusasaziweyo kunye nolwelo olusasaziweyo, ilandelwa yi-condensing, i-washing. Ineempawu ezibalaseleyo ezinjengokumelana nobushushu, ukumelana nemozulu, ukumelana nokubanda, ukukhuhlana okuphantsi, ukunganamatheli, ukuzinza kweekhemikhali, kunye nokugqunywa kombane. Ukongeza, ngenxa yobungakanani bamasuntswana asezantsi, inokwabiwa kakuhle kwaye kulula ukuyixuba ngokufanayo nezinye izinto. Polytetrafluoroethylene (PTFE) ultrafine umgubo micro imhlophe ephantsi ubunzima molekyuli umgubo free-oqukuqelayo kunye nesakhiwo ezinzileyo molecular equlathe -(-CF2-CF2-)n, nto leyo ebalaseleyo ukumelana imichiza, uzinzo thermal, ukumelana nemozulu ephezulu (ngaphezu kweminyaka elishumi), UV ukumelana, ukumelana nobushushu obuphezulu (ubushushu bexesha elide besicelo bujikeleze i-260 ° C), uluhlu olubanzi lobushushu (-200 ukuya + 260 ° C), iipropati ezilungileyo ezingabambekiyo, ukufakwa kombane okuphezulu (1017Ωcm), ukubuyiswa komlilo, kunye nokugqwesa. iipropati zokuzithambisa.
Iimpawu ezizodwa
PTFE umgubo omncinci iimveliso zihlambuluke kwi-100%, ubunzima be-molecular obungaphantsi kwe-10,000, kunye nobukhulu be-particle kuluhlu lwe-0.5-15μm. Abagcini nje ngokugcina zonke iipropathi ezigqwesileyo zepolytetrafluoroethylene kodwa banezinto ezininzi ezizodwa, ezinje ngokungazihlanganisi, akukho siphumo sombane esingatshintshiyo, ukunyibilika kakuhle, ubunzima bemolekyuli obuphantsi, ukusasazeka okuhle, ukuzithambisa okuphezulu, kunye nokuncipha okubonakalayo kwi-friction coefficient. .
Ukusetyenziswa kwePolytetrafluoroethylene Micro Powder
I-Polytetrafluoroethylene micropowder ingasetyenziswa njenge-lubricant eqinileyo yodwa okanye njenge-additive for plastics, irabha, i-coatings, i-inki, i-oyile yokuthambisa, kunye negrisi. Xa ixutywe neeplastiki okanye irabha, iindlela ezahlukeneyo zokusetyenzwa komgubo ezifana nokuxuba zingasetyenziswa, kwaye isixa sokongeza yi-5-20%. Ukongeza i-polytetrafluoroethylene i-powder encinci kwi-oyile kunye negrisi inokunciphisa i-coefficient ye-friction, kwaye iipesenti ezimbalwa zinokunyusa ubomi be-oyile yokuthambisa. I-organic solvent dispersion yayo ingasetyenziswa njenge-arhente yokukhulula.
