Amanyathelo angqongqo olawulo lomgangatho asetyenziswa kuyo yonke inkqubo yokuvelisa ukuqinisekisa ukusebenza kwemveliso okungaguqukiyo. Oku kubandakanya ukuhlolwa rhoqo kwemathiriyeli ekrwada, ukujonga ukutyeba kokutyabeka kunye nokufana, kunye novavanyo lweempawu zomzimba ezinjengokuqina kokuqina, ukuxhathisa ukukrazuka, kunye nokuguda komphezulu. Ubuchule obukwinqanaba eliphezulu obufana ne-electron microscopy kunye ne-spectroscopy zinokusetyenziselwa ukuhlalutya i-microstructure kunye nokwakheka kweekhemikhali zelaphu eligqunyiweyo. Ukongeza, iimveliso ezigqityiweyo zivavanywa ngokucokisekileyo ukuze ziqinisekise iipropathi zazo ezingabambekiyo, ukumelana nobushushu, kunye nokuqina phantsi kweemeko ezahlukeneyo.
Usetyenziso kunye nezinto eziluncedo ze-PTFE Coated Fiberglass Fabric
Usetyenziso lwemizi-mveliso
Ilaphu le-PTFE eligqunywe nge-fiberglass lifumana ukusetyenziswa kakhulu kwizicelo ezininzi zemizi-mveliso ngenxa yendibaniselwano eyodwa yeepropathi. Kwishishini lokulungisa ukutya, lisebenza njengesixhobo esifanelekileyo samabhanti okuhambisa, amashiti okubhaka, kunye namaphepha okukhulula, enkosi kwindawo yawo engancamathelanga kunye nokuthotyelwa kwe-FDA. Icandelo le-aerospace lisebenzisa eli laphu ukugquma inqwelomoya kunye nokwakhiwa kweradome, lixhamla kubume bayo obukhaphukhaphu kunye nokuxhathisa amaqondo obushushu agqithisileyo. Kwizityalo zokusetyenzwa kweekhemikhali, amalaphu agqunyiweyo e-PTFE aqeshwa kwiinkqubo zokuhluza, amajoyinti okwandisa, kunye neelinen ezikhuselayo, ezenza imali kwi-inertness yazo yeekhemikhali kunye nokuqina.
Izicelo zoYilo lwezakhiwo
Ihlabathi lezokwakha liye lamkela ilaphu le-PTFE eligqunywe nge-fiberglass ngenxa yokuguquguquka kunye nokubukeka kobuhle. Lukhetho oludumileyo lwezakhiwo ezixineneyo, ezinje ngophahla lwebala lemidlalo, iicanopies, kunye neenkqubo zefacade. Ukuguquguquka kwelaphu kuvumela ukuhanjiswa kokukhanya kwendalo ngelixa ibonelela ngokhuseleko lwe-UV, iyenza ilungele ukugqunywa kwe-atrium kunye neenkqubo zokukhanya kwesibhakabhaka. Iipropati zayo zokuzihlambulula, ngenxa ye-PTFE yokugqoka i-non-stick, iqinisekisa iindleko eziphantsi zokugcinwa kunye nokubonakala okubonakalayo okuhlala ixesha elide. Ngaphezu koko, iipropathi zelaphu ezikwaziyo ukumelana nomlilo zinegalelo kukhuseleko lwesakhiwo, ukuhlangabezana neemfuno ezingqongqo zekhowudi yomlilo.
Iingenelo Ezikhethekileyo
Ilaphu le-PTFE eligqunywe nge-fiberglass liqhayisa ngeseti eyodwa yeenzuzo eziyenza yahluke kwezinye izinto. Ukumelana nokushisa kwayo okukhethekileyo kuvumela ukuba ikwazi ukumelana namaqondo okushisa ukusuka kwi -100 ° F ukuya kwi-500 ° F (-73 ° C ukuya kwi-260 ° C) ngaphandle kokuthotywa. I-coefficient ye-friction ephantsi yelaphu inciphisa ukuguga kunye nokukrazula kwiindawo ezihambayo, iphucula ubomi obude koomatshini kunye nezixhobo. Ubume bayo be-hydrophobic buyenza ingabi namanzi, ngelixa iimpawu zayo ze-oleophobic zixhathisa ioli kunye namafutha. Izinto ezigqwesileyo zokugquma umbane ziyenza ilungele ukusetyenziswa kombane ezahlukeneyo. Ngaphaya koko, ukuxhathisa kwayo kwimitha ye-UV kunye nezingcolisi zomoya kuqinisekisa ukuqina kwexesha elide kufakelo lwangaphandle, oko kuyenza ibe sisisombululo esinexabiso elisebenzayo kumashishini amaninzi.
I-Teflon Tape: Ukuqulunqwa, ukusetyenziswa, kunye neMida
Ukubunjwa kunye neePropati
Iteyiphu yeTeflon, ekwaziwa ngokuba yi-PTFE tape okanye iteyiphu yomtywini, yimathiriyeli ebhityileyo, eyolulekayo eyenziwe ikakhulu yi-polytetrafluoroethylene (PTFE). Ngokungafaniyo ne-PTFE eqatywe ilaphu le-fiberglass , iteyiphu yeTeflon ayinayo i-substrate yokuqinisa. Iteyiphu iveliswa ngenkqubo ebizwa ngokuba yicoca extrusion, apho i-PTFE resin ixutywa ne-lubricant kwaye inyanzeliswe ngokufa ukwenza ifilimu ebhityileyo, enemingxuma.
