Kodi Polytetrafluoroethylene Micro Powder ndi chiyani?
Polytetrafluoroethylene Micro Powder, wotchedwanso low molecular weight polytetrafluoroethylene yaying'ono ufa, polytetrafluoroethylene ultrafine ufa, ndi polytetrafluoroethylene sera, ndi woyera powdery utomoni wopezedwa ndi polymerization wa tetrafluoroethylene mu omwazika otsika madzi, kutsatiridwa ndi omwazika otsika madzi, ndi kutulutsa madzi omwazika, otsika ndi otayira owuma. ufa wopanda kulemera.
Introduction
Polytetrafluoroethylene micropowder, yemwenso amadziwika kuti otsika maselo kulemera polytetrafluoroethylene yaying'ono ufa kapena polytetrafluoroethylene ultrafine ufa kapena polytetrafluoroethylene sera, ndi woyera powdery utomoni akamagwira polymerization wa tetrafluoroethylene mu omwazika madzimadzi omwazika, kutsatiridwa ndi condensing, kupukuta, kupukuta, kuchapa. Ili ndi zinthu zabwino kwambiri monga kukana kutentha, kukana nyengo, kukana kuzizira, kukangana kochepa, kusamata, kukhazikika kwamankhwala, komanso kutsekereza magetsi. Kuphatikiza apo, chifukwa cha kukula kwake kwa tinthu tating'onoting'ono, imakhala ndi dispersibility yabwino ndipo ndiyosavuta kuphatikiza ndi zida zina. Polytetrafluoroethylene (PTFE) ultrafine yaying'ono ufa ndi woyera otsika maselo kulemera kwaulere-othamanga ufa ndi khola maselo dongosolo wopangidwa -(-CF2-CF2-) n, amene ali kwambiri kukana mankhwala, matenthedwe bata, mkulu weathering kukana (zaka zoposa khumi), UV kukana, kukana kutentha kwanthawi yayitali (kutentha kwa nthawi yayitali kumakhala kozungulira 260 ° C), kutentha kwakukulu (-200 mpaka +260 ° C), zinthu zabwino zopanda ndodo, kutchinjiriza kwamagetsi apamwamba (1017Ωcm), kuchedwa kwamoto kwambiri, komanso zabwino kwambiri. zodzipangira mafuta.
Katundu wapadera
PTFE micro powder Zogulitsa zimakhala ndi chiyero cha 100%, kulemera kwa maselo osakwana 10,000, ndi kukula kwa tinthu mumtundu wa 0.5-15μm. Sikuti amangosunga zabwino zonse za polytetrafluoroethylene komanso amakhala ndi zinthu zambiri zapadera, monga kusakhala ndi agglomeration, palibe mphamvu yamagetsi yokhazikika, kusungunuka kwabwino, kutsika kwa maselo, kufalikira kwabwino, kudzipangira mafuta, komanso kuchepetsa kwambiri kukangana kokwanira. .
Kugwiritsa ntchito Polytetrafluoroethylene Micro Powder
Polytetrafluoroethylene micropowder ingagwiritsidwe ntchito ngati mafuta olimba okha kapena ngati chowonjezera cha mapulasitiki, mphira, zokutira, inki, mafuta opaka mafuta, ndi mafuta. Mukasakaniza ndi mapulasitiki kapena mphira, njira zosiyanasiyana zopangira ufa monga kusakaniza zingagwiritsidwe ntchito, ndipo kuchuluka kwake ndi 5-20%. Kuonjezera polytetrafluoroethylene ufa wawung'ono ku mafuta ndi mafuta kumatha kuchepetsa kugundana, ndipo ochepa peresenti amatha kuwonjezera moyo wamafuta opaka mafuta. Kubala kwake kosungunulira kwachilengedwe kungagwiritsidwenso ntchito ngati chotulutsa.
