Izinto Eziphembelela Ukutyeba kweFayibha ye-Fiberglass ene-Coated
Ulwakhiwo lweFabric esisiseko
Ubukhulu belaphu le-PTFE elenziwe nge-fiberglass liphenjelelwa kakhulu kukwakhiwa kwelaphu lesiseko. Ilaphu le-Fiberglass lisebenza njengesiseko se-PTFE yokwambathisa, kwaye ipateni yayo yokuluka, ubungakanani bomsonto, kunye nokubalwa komsonto kudlala indima ebalulekileyo ekumiseleni ubukhulu bubonke. Amalaphu e-Plain weave athande ukuba mancinci kwaye abhetyebhetye ngakumbi, ngelixa i-twill weave inika amandla amakhulu kunye nokuqina kancinci. I-denier yomsonto we-fiberglass ikwachaphazela ubukhulu belaphu, kunye nemisonto ephezulu ye-denier ekhokelela kumalaphu angqindilili.
PTFE Coating Indlela
Indlela esetyenziswayo yokufaka i-PTFE yokwambathisa ichaphazela ukutyeba kokugqibela kwelaphu. Idiphu yokwaleka, umzekelo, ivumela ulawulo oluchanekileyo phezu kobunzima bokugquma, njengoko iidiphu ezininzi zinokwenziwa ukufezekisa iziphumo ezifunwayo. Ukutshiza, kwelinye icala, kunokuvelisa umaleko ofanayo kodwa kunokuba nzima ukulawula iileya ezibhityileyo. I-viscosity ye-PTFE ye-dispersion kunye nesantya senkqubo yokugquma nayo ichaphazela ubukhulu bomgca osetyenzisiweyo.
IiMfuno zesicelo
Usetyenziso olucetywayo lwelaphu ye-fiberglass egqunywe nge-PTFE ihlala ichaza ubukhulu bayo. Kwiindawo ezinobushushu obuphezulu, amalaphu atyebileyo anokukhethwa ukuze abonelele ngcono kwaye ahlale eqinile. Ngokwahlukileyo, izicelo ezifuna ukuguquguquka kunye neempawu ezikhaphukhaphu zinokukhetha amalaphu amancinci. Imizi-mveliso efana ne-aerospace, ukusetyenzwa kokutya, kunye nokuveliswa kweekhemikhali nganye ineemfuno ezizodwa eziphembelela ukhetho lobukhulu belaphu. Kubalulekile ukuqwalasela imiba efana nokunganyangeki kweekhemikhali, amandla e-dielectric, kunye ne-thermal conductivity xa ukhetha ubukhulu obufanelekileyo kwisicelo esithile.
Iinkqubo zokuVelisa ukutyeba okwahlukeneyo
Ubuchwephesha bokuQamba obuchanekileyo
Ukufezekisa ukuqina okungaguquguqukiyo kunye nobuchanekileyo kwilaphu le-fiberglass egqunywe nge-PTFE kufuna ubuchule obuphambili bokwenza. Enye indlela enjalo yi-knife-over-roll coating, evumela ulawulo olugqwesileyo phezu kobunzima bokugquma. Le nkqubo ibandakanya ukugqithiswa kwelaphu le-fiberglass ngokusebenzisa umsantsa obekwe ngokuchanekileyo phakathi kwemela kunye ne-roller, ukuqinisekisa isicelo esifanayo se-PTFE. Kwiingubo zokwaleka ezibhityileyo kakhulu, abavelisi banokusebenzisa i-gravure coating, apho irola eyenziweyo igqithisela isixa esithile se-PTFE yokusasazwa kumphezulu welaphu. Ezi ndlela zichanekileyo zivumela ukuveliswa kweendwangu ezinobunzima obungaphantsi kwe-0.003 intshi ngelixa ugcina umgangatho ohambelanayo.
Iinkqubo zoKutyabeka ngoMaleko amaninzi
Kwi -PTFE ejiyileyo egqunywe nge-fiberglass ilaphu , abavelisi bahlala besebenzisa iinkqubo zokwaleka ezinomaleko amaninzi. Le ndlela ibandakanya ukusebenzisa iileya ezicekethekileyo ezininzi ze-PTFE dispersion, umaleko ngamnye unyangwa phambi kokuba kusetyenziswe okulandelayo. Ubuchwephesha be-multi-layer buvumela ulawulo olungcono phezu kobunzima bokugqibela kwaye bungabangela ukunamathela okuphuculweyo phakathi kwe-PTFE yokugqoka kunye ne-fiberglass substrate. Ukongeza, le ndlela inokubandakanya iindlela ezahlukeneyo ze-PTFE kwimaleko nganye, ilungelelanisa iipropati zelaphu kwiimfuno ezithile ezifana nokuchasana kweekhemikhali okuphuculweyo okanye ukuphucuka kweempawu zokukhulula.
Unyango lobushushu kunye neSintering
Ubukhulu bokugqibela kunye neepropathi ze-PTFE ezigqunywe ngelaphu le-fiberglass ziphenjelelwa kakhulu lunyango lobushushu kunye neenkqubo ze-sintering. Emva kokugquma, ilaphu lihamba kumjikelezo wokufudumeza olawulwa ngononophelo osusa izinyibilikisi ezishiyekileyo kwaye zidibanise amasuntswana e-PTFE kwifilimu eqhubekayo. Ubushushu be-sintering kunye nobude bunokuchaphazela ubuninzi kunye nobukhulu bomaleko we-PTFE. Ubushushu obuphezulu be-sintering bunokubangela ukujiya, ukugquma kancinci, ngelixa amaqondo obushushu asezantsi anokuvelisa ubume obunemingxuma ngakumbi. Abavelisi kufuneka balinganise ngokucokisekileyo ezi parameters ukufezekisa ubukhulu obufunwayo kunye neempawu zokusebenza kwelaphu eligqityiweyo.
