Teflon la safeeyey waa waalka isticmaala polytetrafluoroethylene (PTFE, oo sidoo kale loo yaqaan Teflon) sida shaabad, waxaana si ballaaran loo isticmaalaa meelo badan sababtoo ah faa'iidooyinka waxqabad ee gaarka ah. Warqadani waxay soo bandhigi doontaa faa'iidooyinka waxqabadka iyo goobaha codsiga ee afar-fluorine ee waalka leh.
Marka hore, faa'iidooyinka waxqabadka ee valves PTFE
1. Iska caabbinta daxalka aad u fiican: dusha daboolka ee waalka teflon wuxuu ka samaysan yahay maaddada polytetrafluoroethylene, kaas oo leh xasillooni kiimiko oo aad u sarreeya oo iska caabin kara daxalka inta badan warbaahinta kiimikada, oo ay ku jiraan acids xooggan, alkali, dareerayaasha organic, iwm, sidaas darteed waxay qabataa. sidoo kale duurka ku ah gaadiidka daxalka.
2. Isku-dhafka hooseeya ee isku-dhafka: PTFE waxay leedahay isugeyn aad u hooseeya oo isku-dhafan (0.05-0.1), taas oo ka dhigaysa valve PTFE inuu ku guuleysto dhaqdhaqaaq siman inta lagu jiro furitaanka iyo xidhitaanka, yaraynta qulqulka hawlgalka iyo yaraynta isticmaalka tamarta qalabka.
3. Anti-viscosity: polytetrafluoroethylene waxay leedahay anti-viscosity wanaagsan, taas oo ka hortagi karta walxaha in ay ku dhejiyaan dusha daboolka waxayna yareeyaan shaqada dayactirka ee valve.
4. Heerkulka la qabsiga: sheyga shaabadeynta ee PTFE-da xayndaabku wuxuu ka shaqeyn karaa inta u dhexeysa -200 ° C ilaa 260 ° C muddo dheer, wuxuuna u adkeysan karaa heerkulka sare ee waqti gaaban, taas oo ka dhigaysa PTFE-dareeraha la safeeyey waxay noqon kartaa lagu dabaqay deegaan heerkul kala duwan.
5. Waxqabadka badbaadada: Sababtoo ah afar-fluorine-ka daboolan waxay isticmaashaa walxo aan bir ahayn sida dusha daboolka, ma soo saari doonto walxaha waxyeellada leh xitaa xaaladaha daran sida heerkulka sare iyo cadaadiska sare, sidaas darteed waxay leedahay waxqabadka badbaadada sare.
Marka labaad, goobta dalabka ee PTFE-da safan
1. Warshadaha Kiimikada: Qalabka PTFE ee daboolan ayaa si weyn loogu isticmaalaa warshadaha kiimikada, gaar ahaan warbaahinta daxalka ah, aashitada xooggan iyo deegaanka alkali, PTFE-dareenka daboolka ayaa hubin kara hawlgalka badbaadada ee qalabka iyo dhimista kharashka dayactirka.
2. Wershadaha batroolka: Warshadaha batroolka, PTFE-yada khadadka leh ayaa inta badan loo isticmaalaa in lagu qaado saliidda, gaaska dabiiciga ah iyo warbaahinta kale, iyo caabbinta daxalka ee aadka u fiican iyo waxqabadka shaabadeynta ayaa ka dhigaysa PTFE-dareeraha valves ee doorbidaya warshadaha batroolka.
3. Warshadaha dawooyinka: Warshadaha dawooyinku waxay leeyihiin shuruudo sare oo loogu talagalay nadaafadda iyo badbaadada qalabka, iyo tetrafluorolined valve kaliya ayaa buuxinaya shuruudahan, sidaa darteed si weyn ayaa loogu isticmaalaa warshadaha dawooyinka.
4. Warshadaha Elektaroonigga ah: Codsiga PTFE ee xargaha xargaha ee warshadaha elektiroonigga ah ayaa inta badan ka muuqda gudbinta iyo xakamaynta gaasaska saafiga ah iyo dareeraha, iyo waxqabadkeeda wanaagsan waxay xaqiijin kartaa hawlgalka xasilloon ee qalabka elektaroonigga ah.
6. Warshadaha cuntada: Sababtoo ah sifooyinka wanaagsan ee anti-viscosity iyo anti-corrosion of valves lined PTFE, waxay sidoo kale si weyn loogu isticmaalay warshadaha cuntada, sida waxqabadka ugu wanaagsan ee gudbinta warbaahinta viscosity-sare sida sharoobada iyo casiirka.
Marka la soo koobo, PTFE valves lineed ayaa si weyn loogu isticmaalay meelo badan iyadoo loo eegayo faa'iidooyinka waxqabadkooda wanaagsan. Iyada oo horumarinta joogtada ah ee sayniska iyo tignoolajiyada, goobta codsiga ee PTFE ee khaanadaha safan ayaa la sii ballaarin doonaa mustaqbalka.
