Bir la safan Dhuumaha PTFE,Bir la safan Tuubbooyinka PTFE iyo qalabyada ku rakiban waxay ku raaxaystaan sumcadda "King balaastikada".Waxay leeyihiin iska caabin heerkul aad u fiican iyo iska caabin daxalka.Waxay ku fiican yihiin nitric acid, sulfuric acid, hydrofluoric acid, phosgene iyo chlorine., aqua regia, aashitada isku dhafka ah, bromide iyo dareerayaasha kale ee dabiiciga ah iyo qalabka kale ee gudbinta dhexdhexaadka ah ee xooggan.Bir la safan Tuubooyinka PTFE iyo qalabyada ku rakiban oo si deggan ugu socon kara heerkul sare (gudahood 150°C) Xaaladaha cadaadiska xun xun ee muddada dheer waxay xalliyaan cilladihii horeBir la safan Tuubooyinka PTFE iyo qalabyada aan u adkeysan karin cadaadiska xun.Nidaamka ayaa si weyn loo isticmaalay.
Tilmaamaha ugu muhiimsan ee birta PTFE ee tuubada leh
1. Qalabka kiimikada ee tuubada PTFE ee birta ah:
Iska caabinta gabowga atmospheric: caabbinta shucaaca iyo qulqulka hooseeya: soo-gaadhista muddada-dheer ee jawiga, dusha sare iyo waxqabadka ayaa ah mid aan isbeddelin.
Daboolida: Ogsajiinta Xadka tusku waxa uu ka hooseeyaa 90.
Acid iyo alkaline: aan milmi karin asiidh adag, alkalis iyo dareerayaasha organic.
Iska caabin Oxidation: u adkaysata daxalka wakiilka oksaydhaynta xooggan.
2. Tilmaamaha shaqada ee tuubada PTFE ee birta ah:
Waxqabadka: Dhexdhexaad heerkulka shaqada: -100℃~-250℃
Cadaadiska shaqada ee dhexdhexaadka ah: Cadaadis wanaagsan: 2.5MPa, cadaadiska taban ee hoos yimaada heerkulka caadiga ah 70KPa Cadaadiska Corrosion: Steel PTFE tuubo isku dhafan, marka lagu daro lithium birta dhalaalaysa, potassium, sodium, fluoride koloriin, heerkulka sare ee oksijiinta fluorine, socodka fluorine dareeraha, Waxay u adkeysan kartaa ku dhawaad dhammaan warbaahinta kiimikada, oo ay ku jiraan nitric acid iyo aqua regia corrosion, waxay noqon kartaa waqti dheer 230℃-250℃shaqada heerkulka.Steel polyvinylidene fluoride ama tuubo kale oo fluorine u eg vinyl, halogen, hydrocarbons halogenated, wakiilka oxidizing xoog leh, acid karkaraya, alkali, noocyo kala duwan oo dareere organic leeyihiin iska caabin daxalka wanaagsan, laakiin aan u adkaysan si ay u qiiqa sulfuric acid, xoog leh sulfuric acid kulul iyo nitric acid, 90℃ama in ka badan ketones, esters, amines iyo daxalka wakiilka sulfonation-ku-sare.
