Zithini izinto ezisisiseko kunye nolwahluko phakathi kwe-PFA kunye ne-ptfe?

Umahluko obalulekileyo phakathi kwe-PFA kunye ne-tube tubes eziyisebenzisayo, ukwahlula phakathi kwezi zinto zimbini zeplastiki zilungile, i-PFA yimhlophe, i-PFO icocekile; kunye nobume bezinto eziluhlaza, i-PFA yigrama yegranulan, ptfe ngumgubo.
Ngamafutshane, iplastiki ye-PFA yi-copolymer yexabiso elincinci le-perfluoro-propyluorovinyl ye-ether kunye ne-PTFE, ebonakaliswayo ngokuphuculwa kwesisombululo, kodwa akukho tshintsho kwi-vission xa kuthelekiswa nePTFE. Le resin inokulungiswa ngokuthe ngqo kwiimveliso ezisebenzisa iindlela eziqhelekileyo ze-Thermoplastic, zilungele ukwenza iindawo ezingazivumeliyo i-corrosion, zinxibe iinxalenye zetyhubhu, i-Insul-I-Treat, izixhobo zokuThengisa, zityhafile Izixhobo, impompo kunye ne-valings, kunye neziqulatho zekheminyi.
Iqondo lobushushu le-PFA yexesha elide yi-196 - i-260 degrees, inesidima esihle sekhemikhali, ukumelana nazo zonke iikhemikhali kuzo zonke iikhemikhali ezikwiplastiki; Kwangelo xesha linye kukho izinto ezilungileyo zombane, i-insulaction yayo ayichaphazelekanga iqondo lobushushu, ukumelana kwekhemikhali kuyafana ne-PTFE, ilunge ngakumbi kune-vinylidene fluoride.
Kwakhona, i-PFA inobuchasi obungcono kunye nokunyanzelwa kokucinezelwa kune-ptfe, amandla aphezulu e-sunsengation kunye ne-Elongwation ukuya kuthi ga kwi-100-300%. Kunye neepropathi ezifanelekileyo zokulala, ukumelana kwewerakhi egqwesileyo; Idangatye liyibuyisa ukuya kwinqanaba le-V0, i-PFA Tube eyenziwe ngayo inayo le nkqubo ibalaseleyo.

I-Ptfe yiPolytetraflum, le nto ineempawu ze-Acid kunye neAlkali Ukunganyangeki, ukuxhathisa izinyibilikisi ezahlukeneyo, phantse i-insiolden kuyo yonke iminyikisi. Kwangelo xesha, i-ptfe ineempawu zokuchasana nobushushu obuphezulu, inomlinganiso ophantsi kakhulu wokuxabana, ukuze isetyenziswe njengendima ye-obbriction, kodwa ikwaba ngumqeqeshi ofanelekileyo wokucoca imibhobho engaphakathi yemibhobho yamanzi.
Iqinisekisiwe ukuba i-ptfe inokumelana nesalfu nge-themospic; Ukunganyangeki nokungakhathali kunye nokukhanya okuphantsi; Ukuvezwa kwexesha elide ukuya kwimozulu, umphezulu kunye neepropathi zihlala zingaguqukanga. Ikwaxhaka i-AIDS kunye ne-alkalis, kwaye ke ngoko i-insullen kwii-AIDs ezomeleleyo, iziseko kunye nezinyibilikisi zezinto eziphilayo. Ukusebenza kwemibhobho yeplastiki eyenziwe ngezinto ezinjalo akufuneki kube kubi, emva kwayo yonke loo nto, izinto ezingafunekiyo zineempawu ezingentla
