Farashin PTFEFasaloli: kewayon zafin amfani yana da faɗi sosai (Celsius daga - 200 digiri zuwa +260 digiri);Lalacewar mafi yawan sinadarai, sai dai wasu fluorides da alkalinity moltenmetal; Kyakkyawan kaddarorin inji, juriya na tsufa; Kyakkyawan juriya na harshen wuta (Yi daidai da matakin gwajin ASTM-D635 da D470), a cikin iska don daidaita shi azaman kayan hana wuta; sha ruwa......
Dokta Roy Plunkett na DuPont Research Laboratory ne ya gano PTFE-polytetrafluoroethylene a ranar 6 ga Afrilu, 1938. Dupont ya ƙara haɓaka PTFE na asali kuma aka sake shi azaman samfuri a 1945.
Samfurin yana da matukar juriya ga lalata sinadarai kuma yana iya ɗaukar yanayin zafi sama da 500 ° C. Ɗaya daga cikin kayan gida na farko na PTFE shine “PTFE mai rufi kwanon frying”.Kodayake tukunyar tana aiki sosai, ya bambanta da sandunan PTFE da faranti da muke bayarwa.An fesa a kan kusan baƙar fata shafi, sanduna PTFE mai tsabta da zanen gado a cikin PTFE zagaye mashaya tururi kunshin yana da farin farin yadda za a yi amfani da sandunan filastik masana'antu PTFE yadda ake amfani da sandunan PTFE filastik PTFE gaskets da marufi.
Saboda PTFE yana da babban zafin jiki da juriya na sinadarai, yawanci ana amfani dashi don aikace-aikacen bawul.Daga sauƙaƙan bawul ɗin tururi / ruwan zafi zuwa babban zafin jiki, masana'antun sarrafa ruwa caustic bawuloli na sinadarai.Wannan kayan yana da ƙarancin ƙarfi zuwa robobi mai ƙarfi kuma ana iya sarrafa shi cikin sauƙi - ɗayan mafi sauƙin amfani da filastik.Ana iya yin amfani da sandar PTFE zuwa mafi kusancin haƙuri akan yawancin ƙananan sandunan diamita tare da diamita na + .002 "/ - .00".Juriya na sinadaran yana ɗaya daga cikin mahimman kaddarorin da ke da alaƙa da kayan.A flakes ko flakes, PTFE ake amfani da matsayin gasket abu ga high zafi da sinadaran resistant flanges da like.
