In alaabta PTFE, buuxiyeyAlaabta PTFEwaa wax soo saarka ugu weyn, ee dalalka shisheeye buuxiyey PTFE guud ahaan la dhamaystiray by PTFE resin warshad soo saarka, sida Germany Hoechst HosTaflonTF4000 taxane, HosTaflonTF3000 taxane iyo HosTaflon2000 taxane.Shiinaha, maadaama tignoolajiyada wax soo saarka resin PTFE ay ka danbeyso tignoolajiyada farsamaynta, tignoolajiyada buuxinta PTFE waxaa lagu sameeyaa warshadda wax soo saarka.Adigoo ku daraya buuxinayaal kala duwan sida inorganic, birta iyo polymer in resin PTFE si loo hagaajiyo iska caabinta cadaadiska, xidho caabbinta, caabbinta socodka qabow, caabbinta kulaylka, xasiloonida cabbirka ee PTFE.Alaabooyinka la buuxiyey marka la barbar dhigo PTFE saafi ah, iska caabbinta cadaadiska ayaa kordhay 5 ilaa 10 jeer, xirashada caabbinta ayaa kordhay 1000 jeer, isku-dhafka fidinta tooska ah ayaa hoos u dhacay 80%, kuleylka kuleylka ayaa kordhay 5 jeer, wuxuuna yareeyaa caabbinta mugga iyo caabbinta dusha sare, inta badan loo isticmaalo warshadaha makaanikada ee saliida saliidda aan saliidda lahayn, bushings, siddooyinka piston, hagaha qalabka mashiinka, iwm. Sanadihii la soo dhaafay, kiimikooyinka shisheeye ee anti-daxalka, oo ay ka buuxaan PTFE sida dhuumaha, valves, bambooyin, iwm. Codsiga dahaarka ayaa si degdeg ah u koraya, taas oo ah aag cusub oo codsi ah oo PTFE ah.
Marka loo eego shuruudahan sida caadiga ah loo isticmaalo buuxinta waa: fiber galaas, fiber carbon, graphite, ciid quartz, molybdenum disulfide, carbon amorphous, calcium fluoride, budada bronze, ceramics, polyimide, polyphenylene, poly-p-hydroxyformate iyo wixii la mid ah.
Alaabooyinka PTFE ee buuxa ayaa guud ahaan la qaabeeyey: tayada la buuxiyeyAlaabta PTFEwaxay kuxirantahay doorashada buuxinta resin, naqshadeynta qaacidada, heerka homogeneity ee isku dhafka walxaha iyo arrimo kale.Waqtigan xaadirka ah waxaa jira saddex hab oo isku dhafan oo loo isticmaalo in lagu buuxiyo PTFE: (1) habka isku-dhafka qalalan wuxuu u baahan yahay qalab isku-dhafan oo degdeg ah oo aan lahayn meel dhintay, oo lagu dabaqi karo shuruudaha guud ee alaabta.(2) isku dhafka dareeraha, dareeraha waa acetone ama methanol, loogu talagalay PTFE galaas-buuxiyey.Cadaadiska qaabeynta ee alaabada PTFE ee buuxisay waxay kuxirantahay saamiga mugga buuxinta ee PTFE, sida: oo leh 5% cadaadiska wax-qabashada ee 250 bar;oo leh 6% ilaa 10% cadaadiska buuxinta ee 350 bar;oo leh 12% ilaa 25% cadaadiska buuxinta ee 500 bar;oo leh in ka badan 25% cadaadiska wax-qabashada ee 700 bar.Habka shaandhaynta ee alaabta la buuxiyey waxay la mid tahay PTFE saafi ah.Laakin badeecooyinka la buuxiyey ee ay ku jiraan MoS2 waxay u baahan yihiin in lagu shubo dhexdhexaad hawo ah 360 ℃, ama in lagu dhex geliyo nitrogen dhexdhexaad ah 380 ℃.Alaabooyinka la buuxiyey oo ay ku jiraan fiber galaas ah ayaa ku habboon in lagu daro dhexdhexaadiyaha nitrogen.
