PTFE Daaweynta Hydrophilic Plasma Budada
PTFE Daaweynta Hydrophilic Plasma Budada
PTFE budo waxaa si weyn loo isticmaalaa sida wax lagu daro ee daahan kala duwan dareere ku salaysan iyo daahan budo, sida daahan caag ah, rinji alwaax, daahan gariiradda, daahan UV daawaynta, iyo rinji, si loo hagaajiyo ay wax qabad sii daayo caaryada, caabbinta dusha xoqan, lubricity, caabbinta kiimikada. iska caabinta cimilada, iyo biyo-celinta. PTFE budada yar-yar ayaa loo isticmaali karaa sidii saliid adag halkii laga isticmaali lahaa saliidaha dareeraha ah. Waxa kale oo loo isticmaali karaa si loo hagaajiyo qulqulka khad iyo sida wakiilka ka-hortagga xidhashada, oo leh qadarka caadiga ah ee lagu daro 1-3wt%. Waxa kale oo loo isticmaali karaa dahaarka aan dhegta lahayn ee qalabka wax lagu karsado, oo leh qaddarka caadiga ah ee lagu daro oo aan ka badnayn 5wt%. Kala firdhinta dareeraha dabiiciga ah sidoo kale waxa loo isticmaali karaa sidii wakiilka sii daynta. Waxa kale oo loo isticmaali karaa sida wakiilada wax-ku-oolka ah ee waxtarka leh ee caagadaha kala duwan, sida ABS, polycarbonate (PC), polyurethane (PU), iyo polystyrene (PS).
PTFE waa polymer aad u crystalline ah oo laga sameeyay monomers tetrafluoroethylene, oo leh dahaar koronto oo heer sare ah, xiisad dusha hoose oo hooseeysa iyo iskuxiran iskuxiran, dabci la'aan, caabbinta gabowga atmospheric, laqabsiga heerkulka sare iyo hooseeya, iyo sifooyinka farsamada sare.
Si kastaba ha ahaatee, iyada oo ay ugu wacan tahay qaab-dhismeedkeeda aadka u siman iyo kuwa aan cirridka ahayn, la'aanta kooxo firfircoon, iyo crystallinity sare. PTFE waa shay aad u heersare ah oo aan polar-ka ahayn oo leh hydrophobicity xoog leh, kimikal la'aan, tamar hoose oo dusha sare ah, iyo qoyaan liidata iyo ku dhegganaanta agabka kale, taas oo si weyn u xaddidaysa codsigeeda. Sidaa darteed, si loo ballaariyo codsiga PTFE, oogada sare waa in lagu daaweeyaa si kor loogu qaado tamarta dusha sare loona wanaajiyo biyo-mareenkeeda.
Daaweynta Plasma waa mid ka mid ah tignoolajiyada sida degdega ah u koraya PTFE wax ka beddelka dusha sare ee sannadihii la soo dhaafay. Mabda'a wax ka beddelka balaasmaha waa in la isticmaalo bam-bam ama duritaan dusha sare ee polymer-ka si loo soo saaro curaarta jaban ama loo soo bandhigo kooxo shaqeynaya, sidaas darteed kor u qaadista dusha sare si kor loogu qaado ku dheggan dusha walxaha. Gaasaska caadiga ah ee la isticmaalo waxaa ka mid ah oxygen, hydrogen, nitrogen, carbon tetrafluoride, iyo argon. Duminta balasmaha gaaska aan shaqayn waxay bedeli kartaa qaabka dusha sare ee kopolimer-ka.
Plasma waxay ka kooban tahay qaybo firfircoon sida elektaroonnada, ions, iyo xagjirrada xorta ah. Wax ka beddelka dusha sare ee balasmaha waxaa ka mid ah beddelka jirka iyo kiimikaad. Wax ka beddelka jireed waa duqeynta elektaroonigga iyo ions ee dusha sare ee polymer, kaas oo jebiya curaarta kiimikada ee silsiladda polymer, sababa falcelinta nabaad-guurka, oo sameeya badeecooyin nabaad-guur ah oo dhigaa dusha polymerka. Wax ka beddelka kiimikadu waxay ku lug leedahay soo bandhigida kooxaha shaqeeya iyada oo loo marayo xag-jiryo xor ah oo ka falcelinaya dusha polymer, beddelidda isku-dhafka kiimikada ee dusha sare. Beddelka jirka iyo kiimikaad labaduba waxay keeni doonaan isbeddel ku yimaadda hantida dusha sare. Inta lagu jiro daawaynta balasmaha, soo bandhigida kooxaha shaqada iyo falcelinta nabaad-guurka lama kala saari karo laakiin waxay dhacaan isku mar, falcelinta nabaad-guurka waa lama huraan. Furaha wax-ka-beddelka dusha sare ee waxtarka leh waa in la yareeyo falcelinta nabaad-guurka oo la kordhiyo doorka hordhaca kooxeed ee shaqeynaya.
The PTFE wax ka beddelka budada waxay isticmaashaa mashiinka nadiifinta balaasmaha budada ah. Plasma waxay ku shaqeysaa budada si ay si ula kac ah u bedesho sifooyinka jireed iyo kiimikaad, iyada oo la ilaalinayo sifooyinka asalka ah ee budada, si ay u siiso guryaha cusub ee dusha sare, beddelka sifooyinka dusha sare ee hydrophobic ilaa hydrophilic ama lid ku ah, sidaas awgeed hagaajinta qoyaanka qaybaha budada iyo kor u qaadida adhesion ee qaybaha budada ee dhexdhexaadka ah.
