Ukwaleka ukufana ngexesha le-PTFE emulsion imregnation yelaphu le-fiberglass ngumgca wobomi bomgangatho wemveliso. Ukungalingani kokugquma oonobangela: ukungaphumeleli kwentonga (ukuncamathela kwiindawo ezibhityileyo), ubuthathaka bomatshini (uxinzelelo loxinzelelo, ukukrazula), ukungazinzi kombane (ukuqhekeka kombane wehla ukuya ku-1/10), ukungena kweekhemikhali (i-pinhole corrosion), imiba yobukhulu (i-warpage), kunye neziphene zokulungisa (ukuzulazula kwebhanti, ukuguquguquka kobukhulu). Ukwaleka okufanayo kufuna ulawulo oluchanekileyo lwe-emulsion viscosity, umxholo oqinileyo, ukuxinezeleka kwelaphu, izithuba ezixineneyo, kunye neeprofayili zokomisa / ze-sintering kwiindawo ezininzi.

Ilaphu le-PTFE elinobushushu obuphezulu linomlinganiso wokwandiswa kwe-thermal (CTE) ye-30-60 ppm/°C (i-warp/weft) - iphezulu kune-fiberglass yodwa kodwa isezantsi kakhulu kune-PTFE ecocekileyo (100-200 ppm/°C). I-PTFE idlula ngokukhawuleza utshintsho lwevolumu (1-2%) kwi-19 ° C kunye ne-30 ° C yenguqu yesigaba. Ukunqanda ukubambana, ukukrazula, kunye nokudilizwa: ukucinywa koyilo lolwandiso lwasimahla, kunqande ukuxinezeleka ngamaqondo obushushu besigaba, sebenzisa izithinteli ezizenzekelayo kumabhanti okuhambisa, kwaye usebenzise uyilo oluchasene ne-buckling overlap. Ukuhlolwa rhoqo ukuhamba okubandayo kubalulekile.

I-PTFE i-high-temperature yokushisa ilaphu lokubhaka iimathi zinika iingenelo ezine eziphambili: ukusebenza okungagungqiyo (akukho mafutha okanye umgubo ofunekayo, i-pastries ethambileyo ikhupha ngokucocekileyo), uluhlu olubanzi lobushushu (-70 ° C ukuya ku-260 ° C, lukhuselekile kwi-oven ukuya kwisikhenkcisi), ukusebenziseka kwakhona (amawaka emijikelo, kulula ukuyicoca), kunye nokuqhuba ubushushu (ukuthintela ukutshisa, ukulungelelaniswa okuntsundu). I-FDA yomgangatho wokutya iyahambelana, bakhupha iphepha lesikhumba kwaye bagqithise iimethi ze-silicone ngokugqithisela ubushushu obungcono kunye nokucoleka komphezulu.

Ilaphu le-PTFE lobushushu obuphezulu libalulekile kwishishini lempahla edibanisayo. Usetyenziso oluphambili: amabhanti okuhambisa angenamthungo angenasiphelo koomatshini bokudibanisa abaqhubekayo (bathintela ukuncamathela okuncamathelayo okunyibilikayo okushushu, ukuncamathela 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-Fiberglass ukucutheka kwe-thermal ngoyena nobangela wokungazinzi kwetape ye-PTFE. Kubushushu be-PTFE sintering (360-400 ° C), uxinzelelo lokulukwa olushiyekileyo luyakhululwa. Ukuba ayinqandwa, ilaphu liyancipha; ukuba unqandekile, uxinzelelo olufihliweyo luvalelwe, lubangela ukuncipha kamva ngexesha lokunyathela (150-200 ° C) kunye nokushisa kokuphela kokusetyenziswa. Isisombululo: sebenzisa i-fiberglass esele ifakwe ngaphambili kunye ne-<0.5% shrinkage kwi-400 ° C, ukuphelisa uxinzelelo olushiyekileyo ngaphambi kokugubungela.

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 nee-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.

I-Aokai PTFE yaqala imveliso yayo epheleleyo kwi-APFE Shanghai 2026 (Booth 6T602, Hall 6). Iimveliso ezifakiweyo ziquka iiteyiphu ze-PTFE ze-fiberglass, iifilimu ezicocekileyo ze-PTFE, amabanga 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-sealer, amakhaka okutshiza), ukubunjwa kunye nokwenza ucinezelo olushushu (irabha yokubumba, i-PV lamination), ukugqunyelelwa kombane (i-motor slot liners, ukusonga kwentambo), iinwebu zokwakha (uphahla lwesitediyamu, ulwandiso lwemichiza ye-anti-corrosion, iminyaka engama-30+), 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 ziquka: ukuqhekeka (ukomisa ngokukhawuleza, ukukhupha isikhumba), ukufuduka (amasuntswana ahambela phezulu, ibhondi yangaphakathi ebuthathaka), i-pinholes / i-blister (umoya obanjwe okanye umphunga), amabala amhlophe kunye ne-chalking (ukufuduka kwe-surfactant okanye ukuxutywa okungagqibekanga), ukutyheli / ukupheka (ukushisa ngokugqithiseleyo kwezongezo), i-delamination (i-sherinkage ye-shenkling okanye i-learling ye-orenji) 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.

I-PTFE emulsion imregnation yelaphu le-fiberglass ifuna abancedisi abahlukeneyo ukuze bafezekise ukugquma 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-deventfoam conductivity) (ukoma kancinci). Ukukhethwa kuxhomekeke kwi-substrate kunye neemfuno zokusebenza.
