Zonke iintlobo zeemveliso ze-PTFE ziye zadlala indima ebalulekileyo kwiinkalo zoqoqosho zelizwe ezifana noshishino lweekhemikhali, oomatshini, i-electronics, izixhobo zombane, imboni yezempi, i-aerospace, ukukhuselwa kwendalo kunye neebhulorho.
Ibhodi yeTetrafluoroethylene ilungele ubushushu be -180℃~+250℃.Isetyenziswa kakhulu njengezinto zokugquma umbane kunye ne-linings yokunxibelelana nemidiya eyonakalisayo, izilayidi ezixhasayo, izitywina zikaloliwe kunye nezinto zokuthambisa.Isetyenziswa kushishino olukhanyayo yifenitshala yekhabhathi etyebileyo., Isetyenziswa kakhulu kwiikhemikhali, amayeza, izitya zoshishino lwedayi, iitanki zokugcina, iiketile ze-reaction tower, izinto ezichasene ne-corrosion lining kwimibhobho emikhulu;inqwelomoya, umkhosi kunye namanye amashishini anzima;oomatshini, ulwakhiwo, izilayidi zebhulorho yezothutho, iintsimbi zesikhokelo;ukuprinta kunye nokudaya, ishishini elikhanyayo, amalaphu Izinto ezichasene nokuncamathela kwishishini, njl.
Izinto eziphathekayo eziluncedo
Ukumelana nokushisa okuphezulu - ubushushu bokusebenza bunokufikelela kuma-250 ° C.
Ukumelana nokushisa okuphantsi - kunobunzima obuhle bomatshini;nokuba iqondo lobushushu liyehla ukuya kwi-196°C, linokugcina ubude be-5%.
Ukumelana ne-Corrosion - inert kuninzi lweekhemikhali kunye ne-solvents, ukumelana ne-acids eqinile kunye ne-alkalis, amanzi kunye neentlobo ezahlukeneyo ze-solvents eziphilayo.
Ukumelana nemozulu-ubomi obudala obungcono kakhulu phakathi kweeplastiki.
I-lubrication ephezulu - i-coefficient ephantsi ye-friction phakathi kwezinto eziqinileyo.
Ukunganamatheli - yeyona ngcinezelo incinci yomphezulu phakathi kwezinto eziqinileyo, ayibambeleli kuyo nayiphi na into, kwaye iipropathi zayo zemishini zine-coefficient encinci ye-friction, eyi-1/5 kuphela ye-polyethylene, eyona nto ibalulekileyo kwi-perfluorocarbon. imiphezulu.Kwaye ngenxa yamandla asezantsi kakhulu e-intermolecular of fluorine-carbon chain, i-PTFE ayincangathi.
I-Non-toxic - ayinayo i-physiologically inert kwaye ayinayo impendulo engalunganga xa ifakwe emzimbeni njengesitya segazi sokwenziwa kunye nelungu ixesha elide.
Iipropati zombane I-PTFE ine-dielectric ephantsi engaguqukiyo kunye nelahleko ye-dielectric kwi-wide frequency range, kunye ne-high breakdown voltage, ukumelana nomthamo kunye nokumelana ne-arc.
Ukumelana nemitha Ukumelana nemitha ye-polytetrafluoroethylene imbi (i-104 rads), kwaye ithotywa yimitha yemitha ephezulu, kwaye iimpawu zombane kunye nezomatshini zepolymer ziyancipha kakhulu.Isicelo PTFE inokucutshungulwa ngokucinezelwa okanye extrusion;ingenziwa kwakhona ibe yi-aqueous dispersion yokwaleka, ukumitha okanye ukwenza imicu.I-PTFE isetyenziswa ngokubanzi njengezinto ezixhathisa ubushushu obuphezulu naphantsi, izixhobo zokugquma, izixhobo zokugquma, izinto zokugquma, izinto zokugquma, njl. amashishini.
Ukumelana nokuguga kwe-Atmospheric: ukumelana nemitha kunye nokunyanzeliswa okuphantsi: ukubonakaliswa kwexesha elide kwi-atmospheric, umphezulu kunye nokusebenza kuhlala kungatshintshi.
Ukungatsha: Isalathisi se-oksijini esilinganiselwe singaphantsi kwe-90.
Ukumelana ne-Acid kunye ne-alkali: ayinyibiliki kwi-asidi eyomeleleyo, i-alkali eyomeleleyo kunye ne-organic solvent.
Ukuxhathisa kwi-oxidation: Iyakwazi ukuxhathisa ukubola kwee-oxidants ezinamandla.
I-Acidity kunye ne-alkalinity: ingathathi hlangothi.
Iimpawu zoomatshini ze-PTFE zithambile.Inamandla asezantsi kakhulu.
I-Polytetrafluoroethylene (F4, PTFE) inoluhlu lwemisebenzi emihle kakhulu: ukumelana nobushushu obuphezulu - ubushushu bokusetyenziswa kwexesha elide 200 ~ 260 degrees, ukumelana nokushisa okuphantsi - kusethambile kwi-degrees -100;ukumelana ne-corrosion - ukumelana ne-aqua regia kunye nazo zonke i-solvents eziphilayo;Ukumelana nemozulu-obona bomi buguga kakhulu phakathi kweeplastiki;i-lubricity ephezulu-i-coefficient encinci ye-friction (0.04) phakathi kweeplastiki;i-non-stick-eyona ngcinezelo incinci yomhlaba phakathi kwezinto eziqinileyo ngaphandle kokunamathela kuyo nayiphi na into;non-toxic-inert physiologically;Iipropati zombane ezigqwesileyo, yinto efanelekileyo yokugquma i-Class C.
