INzululwazi ngasemva kwe-PTFE yokuNcamagusha kweTape yokuNchasa ubushushu
Ulwakhiwo lweMichiza ye-PTFE
Ukumelana nobushushu okukhethekileyo kwe-PTFE kuvela kukwakheka kweekhemikhali ezizodwa. Ipolymer iqulathe ikhonkco elide leathom zekhabhoni, nganye idityaniswe kwiiathom ezimbini zefluorine. Esi sakhiwo sidala imolekyuli ezinzile ngokumangalisayo ekwaziyo ukumelana namaqondo obushushu aphezulu ngaphandle kokuwohloka.
Iibhondi ze-carbon-fluorine kwi-PTFE ziphakathi kwezona zinamandla kwi-organic chemistry. Ezi bhondi zifuna isixa esibalulekileyo samandla ukuphuka, yiyo loo nto i-PTFE inokugcina iipropati zayo nakwiqondo lobushushu eliphakamileyo. Iiathom zefluorine nazo zenza i-sheath ekhuselayo ejikeleze i-carbon backbone, iphucula ngakumbi uzinzo lwemathiriyeli.
Ngaphezu koko, iimolekyuli ze-PTFE zinobunzima obuphezulu bemolekyuli kwaye azikho polar. Olu phawu lunegalelo kumandla omgangatho ophantsi wemathiriyeli, oyenza ikwazi ukumelana neekhemikhali kunye nokunamathela kwezinye izinto, nokuba kubushushu obuphezulu.
Iipropati zoThermal ze-PTFE
I-PTFE ibonisa iimpawu zokufudumala eziphawulekayo ezinegalelo ekuchaseni ubushushu obuphezulu. Izinto eziphathekayo zinendawo yokunyibilika ephezulu malunga ne-620 ° F (327 ° C), evumela ukuba igcine ifom yayo eqinile kunye neempawu zomatshini kumaqondo obushushu ngaphezu kwalawo adibana nawo kwizicelo ezininzi zoshishino.
Ukongeza, i-PTFE ine-coefficient ephantsi yokwandiswa kwe-thermal.
