Iyi ngingo igereranya ubunyangamugayo butatu bwo gukiza impamyabumenyi yo gupima silicone yumuvuduko ukabije. Gukuramo ibishishwa (ibirimo gel) bipima igice cyurusobe rudacogora binyuze mu gukuramo Soxhlet - kurenza urugero bitewe nibice byiziritse kumubiri bibeshye nkibihuzabikorwa, 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 zikunze kuboneka zirimo: guturika (gukama vuba cyane, uruhu rwo hejuru), kwimuka kwimuka (uduce twimuka hejuru, inkomoko yimbere imbere), pinholes / blistes (umwuka wafashwe cyangwa umwuka), ibibara byera hamwe na chalking (kwimuka kwa surfactant cyangwa fusion ituzuye), umuhondo / kokiya (ubushyuhe bukabije bwinyongeramusaruro), gusibanganya (kugabanuka kwinshi) 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 ikomeye / alkalis), reaction ya tanki (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 byo guhuza organosilane birema ibiraro bya molekuline hagati ya fibre yikirahure kama 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.
