Wararka - Maxay PTFE u taagan tahay

Polytetrafluoroethylene (PTFE), oo ah nooc ka mid ah isku-dhafka molecular-ka sare, wuxuu leeyahay xasillooni kiimiko oo aad u fiican iyo iska caabin daxalka. Waa mid ka mid ah walxaha ugu fiican ee u adkaysta daxalka adduunka maanta. Marka laga reebo sodium dhalaalay iyo fluorine dareere ah, waxay u adkaysan kartaa dhammaan kiimikooyinka kale. Isma beddeli doonto ka dib marka lagu kariyo aqua regia. Si ballaaran ayaa loogu kala firdhiyaa agab kala duwan oo u baahan iska caabin aashitada, alkali iyo dareeraha dabiiciga ah), Shaabadaynta, saliidayn sare iyo aan dheg lahayn, dahaarka korontada iyo adkeysi wanaagsan oo ka hortagga gabowga, iska caabin heerkul oo aad u fiican (waxay shaqayn kartaa heerkul ah +250℃ ilaa -180℃ muddo dheer). Hadda aan si fiican u eegno sifooyinka kala duwan ee walaxdan iyo codsigeeda.

Tuubada PTFEwaxaa lagu sameeyaa habaynta cadaadiska ama xoqidda; waxaa sidoo kale loo samayn karaa kala firdhinta biyaha si loogu dahaadho, loo nuugo ama loo sameeyo fiilooyinka. Polytetrafluoroethylene waxaa si weyn loogu isticmaalaa warshadaha sida tamarta nukliyeerka, difaaca qaranka, hawada sare, elektarooniga, korontada, kiimikada, mishiinada, qalabka, mitirrada, dhismaha, dharka, daawaynta dusha sare ee birta, daawooyinka, daaweynta caafimaadka, dharka, cuntada, birta iyo dhalaalinta, iwm., agabka u adkaysta daxalka, agabka dahaarka, dahaarka ka hortagga dhegta, iwm., taasoo ka dhigaysa badeecad aan la beddeli karin. PTFE waxay leedahay sifooyin dhammaystiran oo heer sare ah, iska caabin heerkul sare, iska caabin daxalka, aan dheg lahayn, is-saliidayn, sifooyin dielectric oo aad u fiican, iyo isku-darka aad u hooseeya ee is-jiidashada. Iyadoo loo isticmaalo balaastikada injineernimada, waxaa laga samayn karaa tuubooyinka PTFE, ulaha, suunka, taarikada, filimada, iwm. Guud ahaan waxaa loo isticmaalaa dhuumaha u adkaysta daxalka, weelasha, bambooyinka, waalka, radar, qalabka isgaarsiinta ee soo noqnoqda sare, iyo qalabka raadiyaha oo leh shuruudo waxqabad sare leh. Marka lagu daro buuxin kasta oo u adkaysan kara heerkulka sintering ee PTFE, sifooyinkeeda farsamada si weyn ayaa loo hagaajin karaa. Isla mar ahaantaana, sifooyinka kale ee aadka u fiican ee PTFE waa la ilaaliyaa. Noocyada la buuxiyay waxaa ka mid ah fiber galaas, bir, oksaydh bir ah, graphite, molybdenum disulfide, fiber kaarboon, polyimide, EKONOL... iwm. Iska caabbinta xirashada iyo qiimaha xadka PV waxaa lagu kordhin karaa 1000 jeer.

TheTuubada PTFEwaxaa laga sameeyay resin polytetrafluoroethylene ah oo la suray iyada oo loo marayo habka wax lagu shubo ee loo yaqaan 'plumber extrusion'. Balaastigga la yaqaan, PTFE waxay leedahay iska caabinta kiimikada ugu fiican iyo sifooyinka dielectric. Baakadaha tidcan ee PTFE waa walxo shaabad firfircoon oo wanaagsan. Waxaa laga tolay cajalad PTFE oo la ballaariyay. Waxay leedahay sifooyin aad u fiican sida isku-dhafka hoose ee is-goysyada, iska caabinta xirashada, iska caabinta daxalka kiimikada, shaabad wanaagsan, aan hydrolysis ahayn, iyo aan adkayn. Waxaa loo isticmaalaa shaabadeynta gasketka iyo walxaha saliidaynta ee ka shaqeeya warbaahinta kala duwan, iyo sidoo kale dahaarka korontada ee loo isticmaalo mawjadaha kala duwan. Dielectric-ka Kondensarka, dahaarka fiilada, dahaarka qalabka korontada, iwm. Filimka PTFE wuxuu ku habboon yahay dahaarka dielectrics-ka kondensarka, fiilooyinka gaarka ah, dahaarka siligga, dahaarka korontada iyo qalabka iyo dahaarka shaabadaynta. Waxa kale oo loo isticmaali karaa cajalad aan dhegdheg lahayn, cajalad shaabadaysan, iyo dahaarka
