Ukuqonda ukuBunjwa kunye neePropati ze-PTFE Coated Fabrics
Ulwakhiwo lwe-PTFE Coated Fabrics
Amalaphu agqunywe nge-PTFE aquka imathiriyeli esisiseko, ngokuqhelekileyo i-fiberglass, eqatywe nge-polytetrafluoroethylene (PTFE). Le ndibaniselwano eyodwa iphumela kwizinto ezizuza amandla e-fiberglass kunye ne-inertness yekhemikhali ye-PTFE. I-fiberglass substrate inika amandla agqwesileyo okuqina kunye nokuzinza kwe-dimensional, ngelixa i-PTFE yokwambathisa inika iipropati ezingezizo, ukuxhathisa iikhemikhali, kunye nokunyanzeliswa kobushushu.
Inkqubo yokwaleka ibandakanya ukusebenzisa iileya ezininzi ze-PTFE kwi-fiberglass substrate. Ubukhulu kunye nenani leeleya zingenziwa ngokwezifiso ukuhlangabezana neemfuno ezithile. Amanye amalaphu anokuba nomxholo we-PTFE osuka kwi-15% kwizicelo ezinobunwele ukuya kwi-85% yeemveliso ezigqunywe kakhulu. Oku kuguquguquka kuvumela abavelisi ukuba balungelelanise iipropathi zelaphu kwiimveliso ezahlukeneyo kunye nosetyenziso lwezorhwebo.
Iipropati zoThermal ze-PTFE
I-PTFE, icandelo eliphambili kula malaphu e-Teflon agqunywe nge-coated , iqhayisa ngeempawu ezimangalisayo zokushisa. Inendawo yokunyibilika emalunga ne-327°C (620°F) kwaye inokugcina iimpawu zayo zenyama kumaqondo obushushu ukuya kutsho kuma-260°C (500°F). Oku kuxhathisa ubushushu obuphezulu kubalulekile kwizicelo ezikwazi ukumelana nomlilo, njengoko kuvumela ilaphu ukuba ligcine ingqibelelo yalo kunye neempawu ezikhuselayo naxa livezwe kubushushu obugqithisileyo.
Ngaphezu koko, i-PTFE ine-conductivity ephantsi ye-thermal, ethetha ukuba ayidluliseli ubushushu ngokukhawuleza.
