I-PTFE i-high-temperature yokushisa ilaphu yokubhaka i-mats inika iingenelo ezine eziphambili: ukusebenza okungeyona intonga (akukho mafutha okanye umgubo ofunekayo, i-pastries e-ethe-ethe ikhupha ngokucocekileyo), uluhlu olubanzi lobushushu (-70 ° C ukuya kwi-260 ° C, ikhuselekile kwi-oven ukuya kwisikhenkcisi), ukusetyenziswa kwakhona (amawaka emijikelo, kulula ukuyicoca), kunye nokuqhuba ubushushu (ukuthintela ukutshisa, ukulungelelaniswa okumdaka). 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 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-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 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.

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, amabakala achasene ne-static, kunye namabhanti okuhambisa obushushu obuphezulu - ukugubungela ukulungiswa kokutya, 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.

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.

Ilaphu lefiberglass eyandisiweyo (ilaphu lelaphu elikhulu) lahluke kakhulu kwilaphu eliqhelekileyo le-fiberglass kwisakhiwo somsonto. Ngonyango lwejethi yomoya yoxinzelelo oluphezulu, imicu yeglasi eqhubekayo yahlulwa, yahluzwa, kwaye igutyungelwe ibe yivolunous, intambo efana nomqhaphu. Oku kudala ilaphu elijiyileyo, elithambileyo eline-insulation ephezulu ye-thermal (i-air layers evaleleke), ukuhambelana ngcono, ukusebenza kakuhle kokucoca, kunye nokuphuculwa kokumelana nokukrazula / ukuguquguquka - ngexabiso lamandla asezantsi kancinci. Isetyenziselwa igaskets ezinobushushu obuphezulu, ukusonga kwemibhobho, iingxowa zokucoca, kunye nezitywina ze-oveni.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) iphantse yangena kwikhemikhali, kodwa izinto ezithile zibangela ukubola phantsi kweemeko ezithile. Uhlaselo oluthe ngqo lwe-PTFE lwenzeka ngesinyithi esinyibilikisiweyo se-alkali (i-sodium, i-potassium), i-fluorinating agents eyomeleleyo (F₂, ClF₃) kumaqondo obushushu aphezulu, kunye ne-alkali eyomeleleyo etyhidiweyo ngaphezulu kwe-300 ° C. Ukonakala ngokungangqalanga kwenzeka xa i-hydrofluoric acid (HF), i-alkali egxininisiweyo eshushu, okanye i-phosphoric acid eshushu igqobhoza iziphene zokwaleka kwaye ihlasele i-fiberglass substrate. Kwinkonzo yeekhemikhali ezigqithisileyo, sebenzisa ifilimu ecocekileyo ye-PTFE ngaphandle kwe-fiberglass.
