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 iigaskets ezinobushushu obuphezulu, ukusonga kwemibhobho, iingxowa zokucoca, kunye nezitywina ze-oveni.

Ukucoceka kwezinto ezikrwada sisiseko se-PTFE sokusebenza kwelaphu lobushushu obuphezulu. I-emulsion ye-PTFE ecocekileyo (akukho ion zetsimbi, akukho ntsalela ye-molecular-weightweight residues) iqinisekisa ukumelana nobushushu (akukho yellowing ukuya kwi-260 ° C), i-stable non-stick, kunye namandla aphezulu e-dielectric. Kwi-fiberglass, i-alkali-free E-glass (Na₂O <0.8%) igcina amandla kunye ne-insulation kwiqondo lokushisa eliphezulu; iglasi ephakathi/ephezulu yealkali ibangela ukuthotywa. Ukususwa ngokupheleleyo kwee-agents zokuluka kuthintela i-carbonization kunye ne-delamination. Ubunyulu buchaphazela ngqo ubomi benkonzo, ukuthotyelwa kwebakala lokutya, kunye nokuthembeka kombane.

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) 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 ye-PTFE ecocekileyo ngaphandle kwe-fiberglass.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) inokumelana nokuxhathisa ukothuka kwe-thermal ngaphakathi koluhlu lwayo lokusebenza oluqhelekileyo lwe--70 °C ukuya kuma-260°C. Iyakwazi ukunyamezela ukukhwela ibhayisekile kobushushu obukhawulezayo, umz., ukusuka kwi--50°C kwisikhenkcisi ukuya kumatshini wokushicilela oshushu wama-260°C. Amabakala ePremium ade aphumelele ukupholisa ngesiquphe ukusuka kwi-260°C ukuya kwi-10°C emanzini. Nangona kunjalo, ukothusa izinto ezivela kumaqondo obushushu angaphezu kwe-300 ° C (kufuphi ne-PTFE's 327 ° C melting point) kuya kubangela ukuqhekeka kunye nokuchithwa kwangoko. I-fiberglass substrate ibonelela ngokuzinza kwe-dimensional; I-PTFE yokwambathisa yinto ethintelayo.

Ilaphu le-PTFE elinobushushu obuphezulu lisetyenziswa kakhulu kushishino lweekhemikhali kwizicelo ezingundoqo ezisixhenxe: iigaskets zeflange kunye nelayini yombhobho (ixhathise i-acids eyomeleleyo/alkali), i-reactor kunye ne-tank linings (ithintela ukubola kwesinyithi, ukucoca lula), iingxowa zokucoca igesi enomhlwa (ukuya kuthi ga kwi-260°C), i-anti-corrosion expansion, i-anti-corrosion extensions ukubumba okuhlanganisiweyo, kunye nokusonga kombane/kwe-thermal. I-FDA kunye ne-UL amabakala akhoyo.

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 lweqondo lokushisa (-70 ° C ukuya kwi-260 ° C ngokuqhubekayo, i-350 ° C peak), ukuzinza kwe-dimensional (<0.5 kunye ne-buildup-deep), (i-buildup-deep, i-buildup, i-buildup, i-build up). Isetyenziswa kwimibhobho yekhemikhali, iinqaba ze-desulfurization, iitanki zokuchola, kunye nezixhobo zokutya / ze-pharma. Amanqaku e-FDA akhoyo.
