PTFE PFA ee dahaaran tuubooyinka kala duwan ee birta waxay ku habboon yihiin gaasaska daxalka leh iyo dareerayaasha heerkulka sare leh.Noocyada kale ee tuubooyinka isku dhafan ee birta-caaga ah iyo tuubooyinka birta ah kuma habboona gudbinta warbaahinta.Tuubooyinka isku dhafan ee PTFE ee birta ayaa ku habboon.Intaa waxaa dheer, birta polyvinylidene fluoride tuubooyinka isku dhafan ayaa ku habboon in lagu qaado warbaahinta daxalka leh heerkulka shaqada ee -40 ℃ ~ + 150 ℃.

Hordhac Kooban ee Tignoolajiyada Habaynta ee Dhuumaha PTFE ee Birta Leh

Habka isku xidhka daawaynta xalalka tetrafluorotube sodium naphthalene ee birta ku dahaaran

Polytetrafluoroethylene (PTFE) -sodium naphthalene xalka daaweynta habka isku xirka: sodium naphthalene daawaynta maaddooyinka fluorine ku jira, inta badan iyada oo loo marayo falcelinta kiimikada dareeraha wasakhaysan ee caagga PTFE, jeexjeexa qayb ka mid ah atomyada fluorine ee dusha alaabta, si ay dusha sare ugu jirto Lakab kaarboonaysan iyo kooxo polar ah ayaa ku dul hadhay.

Daawaynta xalalka sodium naphthalene ee walxaha ay ku jirto fluorine inta badan waa falcelinta kiimikaad ee u dhaxaysa dareeraha wasakhaysan iyo balaastiga PTFE si ay u jeexjeexaan qayb ka mid ah atamka fluorine ee dusha walaxda, sidaas awgeedna ka tagaysa lakab kaarboonaysan iyo kooxo dabaysha qaarkood dusha sare.Muuqaalka infrared ayaa muujinaya in kooxaha polar sida hydroxyl, carbonyl iyo bonds aan saturated ahayn lagu soo bandhigo dusha sare.Kooxahani waxay kordhin karaan tamarta dusha sare, waxay yareeyaan xagasha xidhiidhka, waxay wanaajiyaan qoyaanka, waxayna ka beddelan karaan mid adag ilaa dhegdheg.Tani waa habka ugu waxtarka badan uguna badan ee la isticmaalo dhammaan hababka hadda la darsay.Guud ahaan, sodium naphthalene tetrahydrofuran waxaa loo isticmaalaa xal etching ah.
