Tsarin samarwa naBututun PTFEshine: PTFE, taimakon extrusion → hadawa → dannawa → busarwa → sintering → sanyaya → samfurin
Tsarin ƙera bututun PTFE ya haɗa da hanyar turawa, hanyar fitarwa, hanyar hydraulic, hanyar walda, hanyar naɗewa, da sauransu, daga cikinsu akwai hanyar turawa. Gabaɗaya, ana amfani da resin PTFE da aka watsar mai girman barbashi na 500μm da kuma yawan da ya bayyana na 0.45gml ~ 0.55gml. Ga ƙananan bututun diamita, yi amfani da resin mai babban matsi, kuma ga manyan bututun diamita, yi amfani da resin mai ƙaramin matsi. Taimakon matsi yawanci yana zaɓar ruhohin ma'adinai 200 da 260. Sarrafa bututun PTFE na biyu na iya samar da bututun PTFE mai raguwar zafi, bututun PTFE mai karkace, bututun hydraulic na PTFE, da sauransu.
An yi bututun Polytetrafluoroethylene da resin polytetrafluoroethylene da aka watsa a zafin ɗaki ta amfani da sinadarin sinadarai na halitta a matsayin taimakon fitar da ruwa, sannan a busar da shi a kuma niƙa shi. Dangane da diamita na bututun, ana iya raba shi zuwa nau'i biyu: bututun yau da kullun da bututun ƙaramin. Diamita na ciki na bututun yau da kullun shine 4mm, kuma diamita na ciki na bututun ƙaramin bai kai ko daidai da 4mm ba.
Tsarin samar da bututun PTFE shine: PTFE, taimakon extrusion → hadawa → latsawa → busarwa → sintering → sanyaya → samfurin.
Bututun Polytetrafluoroethylene suna da ƙarfin injina mai kyau. Gaskets ɗin sune gaskets masu lebur, gaskets masu siffar V, zoben piston, gaskets ɗin bawul ɗin ball, da sauransu, waɗanda aka yi da sandunan PTFE, bututu, da faranti ta hanyar juyawa ko yankewa na inji, waɗanda ke jure tsatsa, juriya da rashin iya aiki.
1. Bututun Teflon gabaɗaya suna amfani da hanyar ƙera matsi, kuma ana iya amfani da ƙera firam ɗin plunger. Ana iya samar da resin da aka samu ta hanyar ƙera polymerization ta hanyar ƙera manna da kuma ƙera calendering.
2. PTFE yana da ƙimar pH na 0-14 (banda ƙarfe na alkali da fluorine a ƙarƙashin zafi mai yawa da matsin lamba mai yawa), wanda zai iya samun ƙarfin injiniya mai kyau tsakanin 100°C da 100°C.
3. Yanayin aikin musamman shine matsin lamba na preforming ya bambanta dangane da siffar da girman samfurin. Amma yawanci ana amfani da shi. Marufi mai kitso na Teflon shine 8-34.3MPa, kuma resin mai cikewa shine 29.4-93MPa. Ga babban ulu mai kauri kusan 600mm a cikin matsi, har yanzu akwai lokacin riƙe matsin lamba na minti 20-30. Lura cewa lokacin da zafin jiki ya yi ƙasa da 185°C. Bututun Teflon zai yi rauni. Gasket ɗin PTFE mai tsabta samfurin rufewa ne mai tsabta wanda ba zai gurɓata duk wani abu da ya taɓa shi ba kuma ana iya amfani da shi sosai a abinci, magunguna da sauran masana'antu.
