Kuma nintambwe ikomeye mubikorwa bya PTFE yubushyuhe bwo hejuru. Inenge zisanzwe zirimo: guturika (gukama vuba cyane, uruhu rwo hejuru), kwimuka kwimuka (ibice byimuka hejuru, guhuza imbere imbere), pinholes / ibisebe (umwuka wafashwe cyangwa umwuka), ibibara byera hamwe na chalking (kwimuka kwa surfactant cyangwa fusion ituzuye), umuhondo / kokiya (gushyuha cyane) ariko imbere imbere (uruhu rwo gufata imitego yubushyuhe), nimpande zimbitse (ingaruka yikawa-impeta). Ibisubizo bikubiyemo imyirondoro yumye, guhumeka neza, hamwe no kwitegura.

Imyenda ya PTFE ikoreshwa cyane mu nganda zikoreshwa mu miti ikoreshwa mu bintu birindwi byingenzi: gasketi ya flange hamwe nu miyoboro (irwanya acide ikomeye / alkalis), reaction ya tank hamwe na tanki (irinda kwangirika kwicyuma, gusukura byoroshye), imifuka yo kuyungurura gaze ya gaz yangirika (kugeza kuri 260 ° C), guhuza amashyanyarazi hamwe no gufunga amashanyarazi, gupfunyika amashanyarazi. Amanota ya FDA na UL arahari.

Ibikoresho byo kurangiza bikoreshwa kumyenda ya fiberglass mbere yo gutwikira PTFE nibyingenzi mubikorwa bya nyuma bya PTFE yubushyuhe bwo hejuru. Ibikoresho byo guhuza organosilane birema ibiraro bya molekuline hagati ya fibre yikirahure idasanzwe na PTFE kama, byongera imbaraga zishishwa kuva <2 N / cm kugeza 4-8 + N / cm. Kuvura neza kandi byongera imbaraga zo kurwanya ubushyuhe (260 ° C +), imikorere ya dielectric, hamwe no kurwanya imiti. Imyenda itavuwe iganisha ku gusiba, kubyimba, no kubaho igihe gito.
