Chii chinonzi Polytetrafluoroethylene Micro Powder?
Polytetrafluoroethylene Micro Powder, inozivikanwawo seyakaderera molecular uremu polytetrafluoroethylene micro powder, polytetrafluoroethylene ultrafine poda, uye polytetrafluoroethylene wax, iwhite powdery resin inowanikwa ne polymerization ye tetrafluoroethylene mune yakapararira yakaderera uye inoomeswa mvura, inoteverwa neyakaparadzirwa mvura, inopera kuoma, inogadzirwa. uremu husina kuyerera hupfu.
ziviso
Polytetrafluoroethylene micropowder, inozivikanwawo seyakaderera molecular uremu polytetrafluoroethylene micro powder kana polytetrafluoroethylene ultrafine poda kana polytetrafluoroethylene wax, is white powdery resin inowanikwa ne polymerization ye tetrafluoroethylene mumvura yakapararira uye yakapararira, inoputika, inoputika, inoputika. Iine zvinhu zvakanakisa zvakadai sekudzivirira kupisa, kuramba kwemamiriro ekunze, kutonhora kwechando, kukwesha kwakaderera, kusanamatira, kugadzikana kwemakemikari, uye kuvharwa kwemagetsi. Pamusoro pezvo, nekuda kwehukuru hwayo hudiki hwepakati, ine yakanaka dispersibility uye iri nyore kusanganisa zvakafanana nezvimwe zvinhu. Polytetrafluoroethylene (PTFE) ultrafine micro poda ichena yakaderera molecular uremu isina-inoyerera poda ine yakagadzikana molecular chimiro inosanganisira -(-CF2-CF2-)n, ine yakanakisa makemikari kuramba, kugadzikana kwekupisa, kukwirira kwemamiriro ekunze (kupfuura makore gumi), UV. kuramba, tembiricha yakakwira (yenguva yakareba tembiricha yakatenderedza 260 ° C), yakafara tembiricha yemhando (-200 kusvika +260 ° C), yakanaka isina-tsvimbo zvivakwa, yakakwira magetsi ekudzivirira (1017Ωcm), kunonoka kwemurazvo, uye zvakanakisa. self-lubricating properties.
Unique ehupfumi
PTFE micro powder zvigadzirwa zvine kuchena kwe100%, huremu hwemamorekuru husingasviki zviuru gumi, uye saizi yechikamu muhuwandu hwe10,000-0.5μm. Ivo havango chengetedza zvese zvakanakisa zve polytetrafluoroethylene asi zvakare vane akawanda akasiyana zvivakwa, senge pasina self-agglomeration, hapana static magetsi mhedzisiro, yakanaka solubility, yakaderera molecular uremu, dispersibility yakanaka, yakakwira yekuzvizora, uye kudzikisira kwakanyanya mukukweshana. .
Zvishandiso zvePolytetrafluoroethylene Micro Powder
Polytetrafluoroethylene micropowder inogona kushandiswa semafuta akasimba ega kana sekuwedzera kune mapurasitiki, rabha, machira, ingi, mafuta ekuzora, uye girizi. Kana yakasanganiswa nemapurasitiki kana rabha, nzira dzakasiyana-siyana dzekugadzirisa hupfu dzakadai sekusanganisa dzinogona kushandiswa, uye huwandu hwekuwedzera i5-20%. Kuwedzera polytetrafluoroethylene micro poda kuoiri uye girizi kunogona kuderedza friction coefficient, uye mashoma muzana anogona kuwedzera hupenyu hwemafuta ekuzora. Yayo organic solvent dispersion inogona zvakare kushandiswa seyakaburitsa mumiriri.
