Ukucoceka kwempahla ekrwada sisiseko se-PTFE somgangatho ophezulu welaphu lobushushu. Ukungcola (iziqalisi ezishiyekileyo, ii-athon zentsimbi, ii-ayinti zentsimbi, ii-agent zokulinganisa ezosulelekileyo) zibangela ukuwohloka kobushushu kwangaphambi kwexesha (amaqamza, amadyungudyungu angaphezu kwama-260°C), imiphezulu engalinganiyo intonga (iendawo zokuncamathela), ukunciphisa ukugqunywa kombane (ilahleko ye-dielectric, ukuqhawuka kombane osezantsi), ukuwohloka kombane ophantsi), ukuwohloka kwamandla omatshini (uxinzelelo olutyheli/ukuqhekeka kombala), ukomelela komatshini kunye noxinzelelo olutyheli. Izinto eziluhlaza ezicocekileyo ziqinisekisa i-FDA-ethobelayo, ubomi obude, i-PTFE yelaphu eliphezulu.

I-PTFE-coated fiberglass sintering yelaphu ifuna ixesha elichanekileyo lokubamba kwi-370-400 °C. Iifurnas eziqhubekayo: 30-90s (encinci) ukuya kwi-3-5 + min (ebanzi). Izithando zeBatch: 5-15 min. I-under-sintering ibangela i-opaque, iingubo ezinqabileyo eziqhekezayo; i-sintering kakhulu ibangela ukuba tyheli, ukubhitya, kunye nokukhutshwa kwerhasi eyityhefu yefluoride. Ukulungiswa kwenkqubo: sebenzisa i-trackers zeqondo lokushisa, yenza uhlolo olubonakalayo (i-semi-transparent, flexible), kwaye wenze iimvavanyo zokutsala iteyiphu. Ngalo lonke ixesha qinisekisa ukutyeba okupheleleyo kobushushu obufanayo.

Ilaphu le-PTFE lobushushu obuphezulu lifuna ukuphathwa ngononophelo ukuqinisekisa ukhuseleko kunye nobomi obude. Amanyathelo okhuseleko angundoqo: ungaze udlule kwi-260 ° C (ngaphezulu kwe-320 ° C ikhupha umsi oyityhefu), thintela ukukrazuka okubukhali (iintanda zokugquma, ziveze i-fiberglass), akukho ukucocwa kwe-abrasive (uboya bentsimbi yonakalisa umphezulu ongengontonga), gcina imvume yokwandiswa kwe-thermal (ithintela ukukrazuka), kwaye ubeke endaweni yayo xa idutyulwe okanye ixotyulwe. Ivenkile iqengqiwe, kude neUV. Nxiba iiglavu ezikhusela ukushisa ngexesha lokuphatha.

Ilaphu le-PTFE lobushushu obuphezulu libalulekile kwishishini lempahla edibanisayo. Usetyenziso oluphambili: amabhanti okuhambisa angenamthungo angenasiphelo koomatshini bokudibanisa abaqhubekayo (bathintela ukuncamathelisa okutshisayo okunyibilikayo, ukuhambisa okungenamibimbi), isigqubuthelo esinganamatheli kunye nelaphu lokugquma lobushushu obucaba (ukhusela iipleyiti kungcoliseko oluncamathelayo), amabhanti okuhambisa amachaphaza okuncamathisela/umgubo wokuncamathisela ngexesha lokuncamathisela. ukomisa / ukuthambisa), kunye nezihlangu zezihlangu zentsimbi zokucofa isampulu. Ukutyeba ukusuka kwi-0.13mm (i-padding elula) ukuya kwi-0.55mm (iibhanti zokuhambisa ezinzima).

Ilaphu le-PTFE elichasene ne-static liphunyezwa ngeendlela ezimbini eziphambili: ukugquma idoping (ukuxuba izihluzi eziqhubayo ezifana nekhabhoni emnyama kwi-emulsion ye-PTFE, ukwenza inethiwekhi ye-percolation ekugxininiseni okubalulekileyo) kunye ne-substrate weaving (ukufaka iintsinga eziqhubayo kwilaphu le-fiberglass). Ukumelana nomphezulu kulawulwa ku-10⁵–10⁹ Ω. Umgaqo: dala indlela eqhubayo ekhupha iintlawulo ezimileyo ngoko nangoko, ukuthintela ukuqokeleleka okuyingozi. Ukuthoba kunyanzelekile ukuze usebenze ngokufanelekileyo.

Ukomisa linyathelo elibalulekileyo kwi-PTFE yokuvelisa ilaphu lobushushu obuphezulu. Iziphene eziqhelekileyo zibandakanya: ukuqhekeka (ukomisa ngokukhawuleza, ukukhupha isikhumba), ukufuduka (amasuntswana ahambela phezulu, ibhondi yangaphakathi ebuthathaka), imibhobho / amadyungudyungu (umoya obanjwe okanye umphunga), amabala amhlophe kunye ne-chalking (ukufuduka kwe-surfactant okanye ukudityaniswa okungaphelelanga), i-yellowing / coking (ukushisa ngokugqithiseleyo kwezongezelelo), i-delamination (i-sherinkage ye-peelleven), i-dealmine (i-sherinkage ye-peelle, i-deeling, i-dealer, i-dealer, i-dealer, i-dealing, i-dealer, ukushwabana), umphezulu womile kodwa ngaphakathi umanzi (ukulusu lubamba ukufuma), kunye nemiphetho engqindilili (isiphumo sekofu). Izisombululo zibandakanya iiprofayili zokomisa ezilawulwayo, ukungena komoya okufanelekileyo, kunye nokunyangwa kwangaphambili kwe-substrate.

Ukomiswa ngokufanelekileyo kwelaphu le-fiberglass kubalulekile kwi-PTFE yokugquma, ukufakwa kwe-resin, okanye ukulaliswa. Izonyango ezintathu eziphambili: ukususwa komswakama kwi-105-120 ° C (i-10-30 min kuxhomekeke kubunzima), ukucocwa kwe-dewaxing / thermal kwi-300-450 ° C (LOI <0.1%, gwema> 500 ° C), kunye nokufudumala kwi-60-100 ° C ngaphambi kokugubungela. Lawula ukufana kweqondo lobushushu be-oveni (±5°C), ukukhutshwa ngenkani, kwaye ukhusele amalaphu afakwe kwi-silane angaphantsi kwe-110°C. Gcina indwangu eyomileyo kwiingxowa ezivaliweyo okanye kumagumbi omileyo (<30 ° C, <40% RH).

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) inika iingenelo ezine eziphambili njenge-anti-corrosion lining: inertness yekhemikhali (imelana ne-aqua regia, i-alkali eqinile, i-solvents), uluhlu olubanzi lobushushu (-70 ° C ukuya kwi-260 ° C ngokuqhubekayo, i-350 ° C peak), ukuzinza kwe-dimensional (<0.5 kunye ne-build-up, i-buildup, i-buildup, i-buildup, i-buildup, i-build up). Isetyenziswa kwimibhobho yekhemikhali, iinqaba ze-desulfurization, iitanki zokuchola, kunye nezixhobo zokutya / ze-pharma. Amanqaku e-FDA akhoyo.

Ilaphu le-PTFE elinobushushu obuphezulu linika iingenelo ezintandathu eziphambili njengebhanti yokuhambisa yoshicilelo: indawo engabambekiyo (intlama yokuprinta kunye nokukhutshwa kweinki ngokucocekileyo), i-260 ° C ukumelana nobushushu (ukomisa okusebenzayo), ukuzinza kwe-dimensional (<0.5% elongation, ubhaliso oluchanekileyo), ukunganyaniseki kweekhemikhali (ixhathisa i-corrosive pastes), i-custom corrosive pastes, i-custom corrosive, i-custombley, kunye ne-custom corrosive pastes anti-static). Ilungele ukuprintwa kwesikrini, ukuprintwa kwedijithali, kunye nezicelo zokudlulisa ubushushu.

Ubomi benkonzo yelaphu lobushushu obuphezulu be-PTFE buyahluka kakhulu ngokwesicelo. I-Chemical anti-corrosion lining ingahlala iminyaka eyi-3+ (i-4x ubude kunerabha). Iitreyi zokubhaka ukutya kwiinyanga ezidlulileyo kunye nokuthotywa okuncinci. Iibhanti zokuthutha zemizi-mveliso zinxiba ukusuka kwingxabano. I-PV lamination (150 ° C, EVA contact) inobomi obuphakathi. Ukusetyenziswa kwe-friction enzima (i-abrasive discs) inobomi obufutshane. Izinto eziphambili: ukulawulwa kweqondo lokushisa (ukuhlala ≤260 ° C), ugweme ukukrazula okubukhali, ukucocwa rhoqo, kunye nokutshintshwa ngexesha elifanelekileyo xa i-blistered okanye iphuzi.
