Waa maxay Polytetrafluoroethylene Micro Powder?
Polytetrafluoroethylene Micro Powder, oo sidoo kale loo yaqaano miisaan yar oo polytetrafluoroethylene budada micro ah, budada polytetrafluoroethylene ultrafine, iyo polytetrafluoroethylene wax, waa budada cad ee budada ah ee laga helay polymerization of tetrafluoroethylene dareere kala firdhiyey, oo ay ku xigto uumi, dhaqid, iyo qalajin hoose si loo soo saaro molecular budo aan qulqulin miisaan.
Hordhac
Budada polytetrafluoroethylene, oo sidoo kale loo yaqaan budada yar ee polytetrafluoroethylene ama budada polytetrafluoroethylene ultrafine ama polytetrafluoroethylene wax, waa xabagta budada cad ee laga helay polymerization of tetrafluoroethylene dareere kala firdhiyey, oo ay ku xigto uumi, dhaqid, iyo qalajin. Waxay leedahay sifooyin aad u wanaagsan sida caabbinta kulaylka, caabbinta cimilada, caabbinta qabowga, khilaaf hoose, dhegeysi la'aan, xasiloonida kiimikada, iyo dahaarka korantada. Intaa waxaa dheer, sababtoo ah cabbirkeeda dhexdhexaadka ah ee yar, waxay leedahay kala firdhisanaan wanaagsan oo ay fududahay in si isku mid ah loogu daro alaabta kale. Polytetrafluoroethylene (PTFE) budada ultrafine micro waa budo lacag la'aan ah oo miisaankeedu yar yahay oo leh qaab dhismeed deggan oo ka kooban -(-CF2-CF2-) n, kaas oo leh caabbinta kiimikada heer sare ah, xasilloonida kuleylka, caabbinta cimilada sare (in ka badan toban sano), UV iska caabin heerkul sare ah (heerkulka codsiga muddada-dheer wuxuu ku dhow yahay 260 ° C), kala duwanaansho heerkul ballaaran (-200 ilaa +260 ° C), guryaha wanaagsan ee aan dhejiska lahayn, dahaarka sare ee korantada (1017Ωcm), dib u dhigista ololka sare, iyo heerkul aad u fiican guryaha is-saliimaynta.
Guryo aan caadi ahayn
PTFE budo yar Alaabooyinku waxay leeyihiin nadiif ah 100%, miisaan kelli ah oo ka yar 10,000, iyo cabbirka qayb ka mid ah inta u dhaxaysa 0.5-15μm. Ma aha oo kaliya inay ilaaliyaan dhammaan sifooyinka wanaagsan ee polytetrafluoroethylene, laakiin sidoo kale waxay leeyihiin sifooyin badan oo gaar ah, sida is-agglomeration, wax saameyn ah oo koronto ah, milmayn wanaagsan, miisaan yar oo kelli ah, kala firdhisanaan wanaagsan, is-saliid sare, iyo hoos u dhac weyn oo ku yimaada isku-xirnaanta isku-dhafka. .
Codsiyada Polytetrafluoroethylene Micro Powder
Micropowder Polytetrafluoroethylene waxaa loo isticmaali karaa sidii saliid adag oo kali ah ama wax lagu daro balaastikada, caag, dahaarka, khadadka, saliidaha saliidda, iyo dufanka. Marka lagu daro balaastiig ama caag, hababka kala duwan ee wax lagu sameeyo budada caadiga ah sida isku-dhafka ayaa la isticmaali karaa, iyo qadarka dheeriga ah waa 5-20%. Ku darista budada yar yar ee polytetrafluoroethylene ee saliidda iyo dufanku waxay yareyn kartaa isku-dhafka isku-dhafka, iyo kaliya boqolkiiba dhowr ayaa kordhin kara nolosha saliidda saliidda. Kala firdhisa dareeraha dabiiciga ah waxa kale oo loo isticmaali karaa sidii wakiilka sii daynta.
