Habka isku-xidhka ee polytetrafluoroethylene (PTFE) - sodium naphthalene xal Polytetrafluoroethylene (PTFE) - Habka daawaynta xalinta sodium naphthalene: Daaweynta xalinta sodium naphthalene ee maadada fluorine-ka ku jirta, inta badan iyada oo loo marayo xalalka daxalka iyo falcelinta kiimikada caaga ah ee PTFE, ka jeex qayb ka mid ah fluorine atamka dusha sare ee maaddada, si ay uga tagaan lakabka carbonization iyo qaar ka mid ah kooxaha polar ee dusha.Daawaynta maaddooyinka fluorine-ku ku jiro ee sodium naphthalene sodium inta badan waa iyada oo loo marayo fal-celinta kiimikada ee u dhaxaysa xalalka daxalka ah iyo balaastiga PTFE si ay u jeexjeexaan qaar ka mid ah atamka fluorine ee dusha sare ee alaabta, sidaas darteed ka tagaya lakabka carbonization iyo kooxaha polar ee dusha sare.IR spectra waxay muujinaysaa in kooxaha polar sida kooxda hydroxyl, kooxda carbonyl iyo bond unsaturated la soo geliyo dusha sare, taas oo kordhin karta tamarta dusha sare, hoos u dhigta xagasha xidhiidhka iyo hagaajinta qoyaanka.Tani waa habka ugu waxtarka badan uguna badan ee loo isticmaalo cilmi-baarista hadda.Sodium naphthalene tetrahydrofuran waxaa guud ahaan loo isticmaalaa xal daxalka.Habka isku xidhka waa sida soo socota: (1) Diyaarinta xal daawaynta: xaddi gaar ah oo biraha sodium waxaa lagu daraa xalka tetrahydrofuran iyo naphthalene, kaas oo jajabka tirada badan ee birta sodium lagu xakameeyo at 3% ~ 5%, iyo Xalka waxaa lagu walaaqayaa heerkulka qolka ilaa 2 saacadood ilaa inta xalku yahay madow madow ama madow;(2) Geli qalabka shaqada ee PTFE si loogu daaweeyo xalka ilaa 5 ~ 10 daqiiqo, ka soo saar, ka dibna ku dhex geli xalka acetone 3 ~ 5 daqiiqo. biyo nadiif ah, ka dibna ku rid mugdiga si ay si dabiici ah u engegaan;( 4) Dooro xabagta epoxy resin, silicone ama polyurethane sidii xabag, si siman u mari dusha si loogu xidho, oo isla markiiba xidho.Ka dib markaad istaagto 24 ~ 30 ℃ 24 saacadood, waxay si adag u xidhi kartaa.
