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-siseko: yenza indlela yokuqhuba ekhupha iintlawulo ezimileyo ngoko nangoko, ukuthintela ukuqokeleleka okuyingozi. Ukuthoba kunyanzelekile ukuze usebenze ngokufanelekileyo.

I-Thickeners kwi-emulsion ye-PTFE ikhonza imisebenzi emine ebalulekileyo: ukumiswa kokumiswa (ukuthintela ukuhlaliswa kwamasuntswana ashinyeneyo e-PTFE), ukuziphatha kwe-shear-thinning (i-viscosity ephezulu ekuphumleni, ephantsi phantsi kokuphazamiseka ukuze kube lula ukugquma), ukulawula ubunzulu bokungena (ulawula ukulayishwa kwe-resin kwilaphu le-fiberglass), kunye nokufana kwefilimu (ukuthintela ukuqhekeka ngexesha lokumisa). Imfuneko ebaluleke kakhulu: i-thickeners kufuneka ibole ngokupheleleyo kwi- ~ 380 ° C iqondo lobushushu le-sintering, ishiya intsalela yothuthu oluyi-zero ukugcina ukucoceka kombane kunye nokugquma kombane.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) inikeza uxhathiso lweekhemikhali ezikhethekileyo, ukumelana ne-acids concentrated (kuquka i-aqua regia), i-alkali eyomeleleyo (kwiqondo lobushushu begumbi), izinyibilikisi eziphilayo, kunye ne-oxidizing agents. Ngaphandle: isinyithi esinyibilikisiweyo sealkali kunye nobushushu obuphezulu bekhompawundi yehalogen ihlasela i-PTFE. Umonakalo wokugquma ubeka i-fiberglass kwi-hydrofluoric acid kunye ne-alkali egxininiswe eshushu. Ubushushu obungaphezulu kwe-260 ° C bunciphisa ukuxhathisa. Kwiindawo ezininzi zeekhemikhali, ilaphu le-PTFE lihlala lizinzile kwaye lithembekile.

Ubushushu obubanzi boluhlu lwe-PTFE tape ifuna i-silicone ye-PSA egcina ukunamathela ukusuka kwi-70°C ukuya kuma-260°C. Izinto eziphambili zoyilo: i-primer-anchored transition layer (ikhusela i-delamination), i-microstructure yesiqithi-selwandle (i-MQ resin islands + i-polysiloxane isigaba esiqhubekayo), i-gradient crosslinking (i-high-density layer yangaphakathi yokuxhathisa i-creep, i-low-density yangaphandle ye-low-temp tack), kunye ne-heat-stabilized fillers (i-oxid oxide). I-Phenyl-modified siloxane segments cinezela i-low-temperature crystallization, eyenza ukuguquguquka ngaphantsi kwe -100 °C.

I-Aokai PTFE yaqalisa uluhlu lwayo olupheleleyo lwemveliso kwi-APFE Shanghai 2026 (Booth 6T602, Hall 6). Iimveliso ezibonakalayo ziquka iiteyiphu ze-PTFE ze-fiberglass, iifilimu ezicocekileyo ze-PTFE, amabakala achasene ne-static, kunye namabhanti okuhambisa obushushu obuphezulu - ukugubungela ukutya, i-PV lamination, iibhetri ze-lithium, i-electronics, kunye nokupakishwa. Lo mboniso uqhuba ngoJuni 26. Zonke iimveliso zixhasa ukucaciswa kwesiko.

Ilaphu elinobushushu obuphezulu be-PTFE liyi-high-tenacity fiberglass kunye ne-PTFE coating. Izicelo eziphambili zokuhambisa ushishino (ukubhaka ukutya, ukomiswa kwelaphu, ukuthuthwa kwePCB), ukukhuselwa kwewelding (izigqubuthelo zobushushu, izihlangu zokutshiza), ukwakhiwa kunye nokwenziwa kocinezelo olushushu (irabha yokubumba, i-PV lamination), ukugqunywa kombane (motor slot liners, ukusonga kwentambo), iimbrane zoyilo (uphahla lwestadium, i-anti-expansining joint corrosion), iminyaka engama-30+ ye-anti i-aerospace (iingubo ze-thermal), kunye nezicelo ezikhethekileyo (ukusika i-laser, ukuprintwa kwe-3D).

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.

Isiphelo esisikiweyo isakhiwo sobuso be-PTFE iteyiphu yobushushu obuphezulu buchaphazela ngokuthe ngqo ukuncamathela okuncamathelayo kunye nokuphakanyiswa komphetho ngexesha lesicelo. Ukucandwa okulambathayo (iincakuba ezibuthuntu, i-engile engafanelekanga) kudala imicu yeglu, ibhitya umaleko wokuncamathelisa, kwaye iveze iifiberglass burrs - ezikhokelela ekujuxuzeni, ekudibaneni okubuthathaka, kunye nokuphakamisa phantsi kobushushu okanye ukuxinana. Ubuso besiphelo esingaqhelekanga (i-wavy, i-protruding) ibangela ukusabalalisa koxinzelelo olungalinganiyo, ukuqhuba i-adhesive creep ngexesha lokugcina. Ubuso besiphelo obufanelekileyo bugudileyo, bugungxulwe, kwaye akukho monakalo-usebenza njengetywina elivala i-adhesive kwaye iqinisekisa ukubopha okugcweleyo.

I-PTFE emulsion imregnation yelaphu le-fiberglass ifuna abancedisi abahlukeneyo ukufezekisa ukoleka okufanayo, ukuncamathela okuqinileyo, kunye neendawo ezingenasiphako. Izongezo eziphambili zibandakanya: ii-agent zokumanzisa (ukunciphisa ukunyanzeliswa komhlaba, ukuphucula ukungena), i-thickeners (ukulawula i-viscosity kunye nobunzima bokugquma), abalawuli be-pH (i-emulsion yokuzinza kwi-pH 9-10), i-silane coupling agents (ukuphucula ukunamathela kwiglasi), i-filimi-forming aids (PFA / FEP ye-sintering), izigcwalisi ezisebenzayo (ukumelana nokuguga, i-deventroxt, i-developers, i-development conductivity) (ukoma kancinci). Ukukhethwa kuxhomekeke kwi-substrate kunye neemfuno zokusebenza.

Ngexesha PTFE tape ukutyabeka, izinga volatilization ukunyibilika of abicah ngoxinzelelo-sensitive adhesive yinkqubo ebalulekileyo parameter. Ukukhawuleza kakhulu → ukusulwa komphezulu, ukungaphakami kakuhle, imingxunya (isinyibilikisi esivalekileyo), kunye nemingxuma (ukujiya okanye ungcoliseko). Ukucotha kakhulu → ukujiya, imiphetho eshinyeneyo, kunye nokumanzisa kwi-PTFE yamandla asezantsi. Esona sicwangciso sifanelekileyo: ukucotha kokuqala ukuguquguquka komgangatho kunye nokuphunyuka kweqamza, emva koko ukoma okukhawulezileyo ukuze kubunjwe. Sebenzisa izinyibilikisi ezixubeneyo (i-toluene/ixylene + ukomisa ngokukhawuleza) kunye nobushushu be-oven yegradient (ephantsi →phakathi → phezulu).
