Iyi ngingo igereranya ubunyangamugayo butatu bwo gukiza impamyabumenyi ya silicone yangiza-yumuti. Gukuramo ibishishwa (ibirimo gel) bipima igice cyurusobe rudacogora binyuze mu gukuramo Soxhlet - kurenza urugero bitewe nuduce twiziritse kumubiri twibeshye nko guhuza, neza ± 2-5%, ubuziranenge bwa chimique. DSC ipima ubushyuhe bwibisigisigi (α = 1-ΔUmuntu / ΔHtotal) - byizewe mugihe gito-giciriritse ariko birenze urugero muguhinduka kwinshi kubera gukwirakwiza amatsinda asigaye, gusubiramo <± 2%.

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 yubushyuhe bwo hejuru ya PTFE ikoreshwa cyane munganda zikora imiti mubikorwa birindwi byingenzi: gasketi ya flange hamwe nu miyoboro (irwanya acide / alkalis ikomeye), reaction ya tank hamwe na tank (irinda kwangirika kwicyuma, gusukura byoroshye), imifuka yo kuyungurura gaze ya gaz yangirika (kugeza kuri 260 ° C), kwangirika kwamashanyarazi hamwe no gufunga amashanyarazi, gupfunyika amashanyarazi. Amanota ya FDA na UL arahari.

Ibikoresho byo kurangiza bikoreshwa mubitambaro bya fiberglass mbere yo gutwikira PTFE nibyingenzi mubikorwa bya nyuma bya PTFE. Ibikoresho bifata organosilane birema ibiraro bya molekuline hagati ya fibre yikirahure idasanzwe na PTFE kama, bikongerera imbaraga ibishishwa kuva kuri <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 gusibanganya, kubyimba, no kubaho igihe gito.
