I-PTFE tape eqengqelekayo inokuphuhlisa i-interlayer adhesion (i-blocking) kunye nokudluliselwa kwe-adhesive ngexesha lokugcinwa kwexesha elide. Iimbangela: ifilimu ye-PTFE imemori elastiki kunye ne-silicone ye-PSA ikhwela phantsi koxinzelelo / ubushushu. Uthintelo: ukuxinezeleka kokuqina okujikajikayo (okuqinileyo ngaphandle, ukukhululeka kwangaphakathi) ngexesha lokwenziwa kwemveliso, kunye nokukhululwa kwetyabeka kwicala elingancamathiseliyo. Gcina kwi -15 ° C ukuya ku-40 ° C, 30-70% RH, ngokuthe tye kwii-racks, ujikeleze i-rolls ngekota. Kumabanga ancamathelayo ashinyeneyo, yongeza iphepha lokukhulula phakathi kweeleya.

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.

Ilaphu elichasayo le-PTFE elinobushushu obuphezulu lidibanisa i-non-stick, ukumelana nobushushu (260°C), kunye neepropati ezingenazo iikhemikhali zomgangatho we-PTFE kunye nokusebenza kwe-static-dissipative. Izicelo eziphambili: ukuveliswa kwe-electronics (i-PCB lamination, ukuphathwa kwecandelo), i-PV module lamination (ikhusela umonakalo we-ESD kwiiseli zelanga), ukutya kunye nokucubungula amayeza (i-ESD-safe baking liners), izityalo zekhemikhali (i-anti-corrosion, i-anti-static ducting), kunye ne-textile / amashishini okushicilela. Ukumelana nomphezulu ngokuqhelekileyo 10⁶–10⁹ Ω.

Iiteyiphu ze-PTFE zobushushu obuphezulu obugcinwe kwifom yomqulu zinokubandezeleka ngenxa ye-interlayer adhesion (ukuthintela) kunye nokudluliselwa kwe-adhesive ukuya kwicala elinganamatheli. Iingcambu ezibangela: ifilimu ye-PTFE imemori elastiki kunye ne-silicone ye-PSA ikhwela phantsi koxinzelelo kunye nobushushu. Isisombululo: I-gradient winding tension - iqinile kumaleya angaphandle, ikhululekile kumaleko angaphakathi - usebenzisa ulawulo lokuxinezeleka oluvaliweyo. Gcwalisa isambatho sokukhululwa, ukugcinwa okufanelekileyo (15-40 ° C, 30-70% RH), ukubekwa okuthe tye, kunye nokujikeleza kwekota.

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.

Iteyiphu yobushushu obuphezulu be-PTFE esetyenziswa kuqhagamshelwano lokutya kufuneka ihloniphe imida yobushushu obungqongqo: ≤260°C ukusetyenziswa rhoqo (akukho mda wexesha), 260-300 °C ukuya kuthi ga kwimizuzu engama-30 kuphela, kwaye> 300 °C akuvumelekanga. Iteyiphu yeyokufowunelwa ngokungathanga ngqo kuphela (i-tray liners, i-heat sealer covers), hayi ukusonga ukutya ngokuthe ngqo. Ungaze usebenze ngaphandle komthwalo wokutya (ukufudumeza okomileyo). Faka enye indawo ukuba inamadyungudyungu, ityheli, okanye igugile.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) ihlala ixesha elide xa igcinwe ngaphantsi kwe-260 ° C, kude neendawo ezibukhali, kwaye zicocwe ngezixhobo ezithambileyo. Izinto eziphambili ezithintela ubomi: ukuthotywa kwe-thermal ngaphezulu kwe-260 ° C, ukothuka kwe-thermal ukusuka ekufudumezeni ngokukhawuleza / ukupholisa, ukudinwa komatshini ngenxa yokugoba kunye noxinzelelo, uhlaselo lweekhemikhali ezivela kwisinyithi esinyibilikisiweyo sealkali okanye i-oxidizers eyomeleleyo, umonakalo ovela kwi-scrapers yesinyithi ngexesha lokucoca, kunye nokuvezwa kwe-UV kusetyenziso lwangaphandle. Umgangatho wokugquma kunye ne-substrate nayo ibalulekile.

Ilaphu le-PTFE elinobushushu obuphezulu lizinzile ukuya kuthi ga kwi-300 ° C, kodwa emlilweni liyabola kwaye likhuphe iigesi ezinetyhefu kakhulu: i-hydrogen fluoride (HF) (i-corrosive, i-pulmonary edema) kunye ne-perfluoroisobutylene (PFIB) (ayinambala, ayinavumba, ~10x inetyhefu ngakumbi kunephosgene, i-antido). Kwakhona i-carbon monoxide, iintsalela zePFOA, kunye nokulandelela iidioxins. Iimaski zomsi eziqhelekileyo azisebenzi; sebenzisa izixhobo zokuphefumla ezizimeleyo (SCBA). Iimpawu zinokulibaziseka.

I-Silicone i-adhesives-sensitive adhesives (PSA) ye-PTFE iiteyiphu zobushushu obuphezulu ziyahluka ngokubanzi ekusebenzeni kokuguga okuphezulu. I-Methylphenyl silicone PSA igcina> i-85% yamandla e-peel emva kwe-250 ° C / iintsuku ze-7, ngelixa uhlobo oluqhelekileyo lwe-methyl luhla kwi-50-70%. Iinkqubo ezongeziweyo (i-hydrosilylation) zinika uzinzo olungcono kakhulu kune-peroxide-nyango. Ngenkonzo eqhubekayo ye-200 ° C+, khetha amabanga aphezulu-phenyl anephenyl.

Iiteyiphu ze-PTFE zokuncamathelisa ngoxinzelelo lwe-thermal-sensitive (PSA) kufuneka ziqhube ubushushu ngelixa zihlala zincangathi. Ukongeza izihluzi ziphucula i-thermal conductivity kodwa kulimaza ukunamathela. Ibhalansi efanelekileyo isebenzisa i-spherical coarse particles (njenge-conductive skeleton) edityaniswe ngamasuntswana amahle (ukugcwalisa i-voids), ukugcina ukulayishwa okupheleleyo kwe-filler nje ngaphezu kwe-percolation threshold. Gwema iiflakes kunye nemicu; babulala intambo.
