Nkhaniyi ikufanizira kulondola kwa njira zitatu zoyezera digirii ya zomatira za silicone. Zosungunulira zosungunulira (zokhala ndi gel osakaniza) zimayesa kagawo kakang'ono ka netiweki kosasunthika kudzera pa Soxhlet m'zigawo - kuyerekezera mopitilira muyeso chifukwa cha magawo omangika mwakuthupi molakwika ngati ma crosslinks, kulondola ± 2-5%, kulondola kwamankhwala otsika kwambiri. DSC imayesa kutentha kotsalira (α = 1-ΔHresidual / ΔHtotal) - yodalirika pa kutembenuka kwapakati-pakatikati koma imapitirira pa kutembenuka kwakukulu chifukwa cha kufalikira-ochepa magulu otsalira, kubwereza <± 2%.

Kuyanika ndi gawo lofunika kwambiri pakupanga nsalu za PTFE zotentha kwambiri. Zowonongeka zodziwika bwino ndi izi: kung'amba (kuyanika mwachangu, kupukuta khungu), kusuntha (tinthu tating'onoting'ono tating'onoting'ono), mapini / matuza (mpweya wotsekeka kapena nthunzi), mawanga oyera ndi choko (kusuntha kwa surfactant kapena kusakanizika kosakwanira), chikasu / kuphika (kutenthedwa kwa zowonjezera), delamination (kutsika kwapang'onopang'ono) shrinkage), pamwamba youma koma mkati monyowa (kukopa misampha chinyontho), ndi m'mbali mwake (zakudya za khofi). Zothetserazo zimaphatikizapo mbiri yowumitsa bwino, mpweya wokwanira, ndi kusamalidwa bwino kwa gawo lapansi.

PTFE mkulu-kutentha nsalu chimagwiritsidwa ntchito makampani mankhwala kwa ntchito zisanu ndi ziwiri zofunika: flange gaskets ndi linings chitoliro (amakana zidulo amphamvu / alkalis), riyakitala ndi linings thanki (kupewa dzimbiri zitsulo, kuyeretsa mosavuta), matumba fyuluta kwa dzimbiri chitoliro mpweya (mpaka 260 ° C), odana dzimbiri kukulitsa, zomangira zomangira, zomangira zomangira, zomangira zomangira, zomangira zomangira, zomangira zomangira zolumikizira. composite akamaumba, ndi magetsi / matenthedwe kutchinjiriza wraps. FDA ndi UL magiredi alipo.

Zopangira zomalizitsa pamwamba zomwe zimagwiritsidwa ntchito pansalu ya fiberglass pamaso pa PTFE zokutira ndizofunikira kwambiri kuti PTFE igwire ntchito ya nsalu yotentha kwambiri. Organosilane coupling agents amapanga milatho ya mamolekyulu pakati pa organic glass fiber ndi organic PTFE, kukulitsa mphamvu ya peel kuchokera pa <2 N/cm mpaka 4-8+ N/cm. Kuchiza koyenera kumathandizanso kukana kutentha (260 ° C+), magwiridwe antchito a dielectric, komanso kukana mankhwala. Nsalu yosasamalidwa imadzetsa delamination, kuphulika, ndi moyo waufupi wautumiki.
