Tsarin samar da bututun PTFE shine: PTFE, taimakon extrusion → hadawa → latsawa → bushewa → sintering → sanyaya → samfur
Tsarin gyare-gyare na bututun PTFE ya haɗa da hanyar turawa, hanyar extrusion, hanyar hydraulic, hanyar walda, hanyar iska, da dai sauransu, daga cikinsu hanyar tura ita ce babbar hanyar.Gabaɗaya, ana amfani da guduro mai tarwatsewa na PTFE tare da girman barbashi na 500μm da ƙarancin ƙarancin 0.45gml ~ 0.55gml.Don ƙananan bututun diamita, yi amfani da guduro tare da matsawa mai girma, kuma ga manyan bututun diamita, yi amfani da guduro tare da ƙaramin matsawa.Taimakon matsi yawanci yana zaɓar ruhohin ma'adinai 200 da 260.The secondary aiki naFarashin PTFEna iya samar da PTFE zafi-shrinkable tubing, PTFE karkace tubing, PTFE na'ura mai aiki da karfin ruwa tubing, da dai sauransu.
Polytetrafluoroethylene bututu an yi shi da polytetrafluoroethylene tarwatsa guduro a dakin da zafin jiki ta amfani da kwayoyin kaushi a matsayin extrusion taimako, sa'an nan kuma bushe da sintered.Dangane da diamita na bututu, ana iya raba shi zuwa nau'ikan guda biyu: bututu na yau da kullun da bututun micro.Diamita na ciki na bututu na yau da kullun shine 4mm, kuma diamita na ciki na ƙananan bututu bai kai ko daidai da 4mm ba.
Tsarin samar da bututun PTFE shine: PTFE, taimakon extrusion → hadawa → latsa → bushewa → sintering → sanyaya → samfur.
Polytetrafluoroethylene bututu suna da kyakkyawan ƙarfin injiniya.Gas ɗin su ne lebur gaskets, gaskets masu siffar V, zoben piston, gaskets ɗin bawul, da sauransu, waɗanda aka yi da su.Farashin PTFE, tubes, da faranti ta hanyar jujjuyawar injiniya ko yanke, waɗanda suke da juriya na lalata , Juriya da rashin aiki.
1. Teflon bututu kullum rungumi matsawa gyare-gyaren hanya, da plunger extrusion gyare-gyaren kuma za a iya amfani da.Da guduro samu ta hanyar watsawa polymerization za a iya kafa ta manna extrusion da calendering.
2. PTFE yana da darajar pH na 0-14 (sai dai narkakken alkali karafa da fluorine a ƙarƙashin babban zafin jiki da matsa lamba), wanda zai iya samun ƙarfin injiniya mai kyau tsakanin 100 ° C da 100 ° C.
3. Yanayin ƙayyadaddun tsari shine cewa matsa lamba na preforming ya bambanta da siffar da girman samfurin.Amma yawanci ana amfani da shi.Teflon braided packing shine 8-34.3MPa, kuma resin tare da filler shine 29.4-93MPa.Don babban ulu tare da kauri na kusan 600mm a cikin latsa matsi, har yanzu akwai lokacin riƙe matsi na 20-30min.Lura cewa lokacin da zafin jiki ya ƙasa da 185 ° C.Teflon tubing zai zama gaggautsa.Tsaftataccen gasket na PTFE shine samfurin rufewa mai tsabta wanda ba zai gurɓata duk wani abu da ya shiga ba kuma ana iya amfani dashi sosai a cikin abinci, magunguna da sauran masana'antu.
