Anti-static PTFE fabric yifikeleriwa hiku tirhisa tindlela timbirhi letikulu: coating doping (ku hlanganisa ti conductive fillers tofana na carbon black eka PTFE emulsion, ku endla percolation network eka critical concentration) na substrate weaving (ku nghenisa ti conductive fibres eka fiberglass cloth). Ku tiya ka le henhla ka misava ku lawuriwa eka 105–109 Ω. Nsinya wa nawu: tumbuluxa ndlela yo fambisa leyi humesaka ti static charges hiku hatlisa, ku sivela ku hlengeletiwa ka khombo. Grounding swa boha leswaku kuta tirha kahle.

Ti thickeners eka PTFE emulsion ti tirha mintirho ya mune ya nkoka: suspension stabilization (yi sivela ku tshamiseka ka ti dense PTFE particles), shear-thinning behavior (viscosity yale henhla loko yi wisa, ehansi ehansi ka agitation kuva yi olova ku peta), penetration depth control (yi lawula ku layicha ka resin eka fiberglass fabric), na film uniformity (ku sivela ku pandzeka loko ku omisiwa). Xilaveko xa nkoka: ti thickeners tifanele ku bola hiku hetiseka eka ~380°C sintering temperature, leswi siyaka zero ash residue kuva swihlayisa ku basa ka coating xikan’we naku pfaleriwa ka gezi.

Lapi ra mahiselo yale henhla ya PTFE (PTFE-coated fiberglass) rinyika ku tiya ka ti khemikhali loku hlawulekeke, ku tiyisela ti acids leti hlanganisiweke (kukatsa na aqua regia), ti alkalis to tiya (eka mahiselo ya kamara), ti organic solvents, na ti oxidizing agents. Swihlawulekisi: tinsimbi ta alkali leti n’okiweke na ti halogen compounds ta mahiselo yale henhla swi hlasela PTFE. Ku onhaka ka ku peta swi veka fiberglass eka hydrofluoric acid na ti alkali to hisa leti hlanganisiweke. Mahiselo yale henhla ka 260°C ya hunguta ku tiya. Eka tindzhawu totala ta ti khemikhali, lapi ra PTFE ritshama ritshamisekile swinene naswona ritshembekile.

Thepi ya PTFE ya mahiselo yo anama yi lava silicone PSA leyi hlayisaka ku namarhela kusuka eka -70°C kuya eka 260°C. Swiphemu swa nkoka swa dizayini: primer-anchored transition layer (yi sivela delamination), sea-island microstructure (MQ resin islands + polysiloxane continuous phase), gradient crosslinking (leyara yale ndzeni ya high-density kuva yi lwisana na creep, leyara yale handle ya low-density ya low-temp tack), na ti fillers leti tiyisisiweke hiku hisa (cerium oxide kuva yi lwisana na oxidation). Swiphemu swa siloxane leswi cinciweke hi phenyl swi tshikelela crystallization ya mahiselo yale hansi, leswi endlaka leswaku kuva na ku cinca cinca ehansi ka -100°C.

Aokai PTFE yi kombisile nxaxamelo wa yona hinkwawo wa swikumiwa eka APFE Shanghai 2026 (Booth 6T602, Holo 6). Switirhisiwa leswi kombisiweke swi katsa tithepi ta PTFE leti tiyisisiweke hi fiberglass, tifilimi ta PTFE to basa, tigiredi ta anti-static, na mabandhi yo fambisa ya mahiselo ya le henhla – lama funengetaka ku lulamisiwa ka swakudya, PV lamination, tibetiri ta lithium, swa elektroniki, na ku paka. Nkombiso wu ya emahlweni ku fikela hi June 26. Switirhisiwa hinkwaswo swi seketela swihlawulekisi swa ntolovelo.

Lapi ra mahiselo yale henhla ya PTFE ya matimba yale henhla i xivumbeko xa fiberglass ya high-tenacity na PTFE coating. Switirhisiwa swa nkoka swi katsa ku hundzisela ka ti indasitiri (ku baka swakudya, ku omisiwa ka swiambalo, ku fambisiwa ka PCB), nsirhelelo wa ku welda (swifunengeto swa heat-sealer, swisirhelelo swa spatter), demolding na ku vumba ka press yo hisa (ku vumba ka rhaba, PV lamination), ku pfaleriwa ka gezi (motor slot liners, cable wraps), ti membranes ta vumaki (mafulelo ya xitediyamu, vutomi bya malembe ya 30+), tikhemikhali ta anti-corrosion (ku andlala swihlanganisi, swifunengeto swa mathangi), swihaha-mpfhuka (swiambalo swo hisa), ni switirhisiwa swo hlawuleka (ku tsema hi laser, ku kandziyisa hi 3D).

Ku omisiwa i goza ra nkoka eka vuhumelerisi bya malapi ya mahiselo yale henhla ya PTFE. Swihoxo leswi tolovelekeke swikatsa: ku pandzeka (ku hatlisa ngopfu ku oma, ku tshoveka ka nhlonge yale henhla), ku rhurha ka coating (ti particles ti famba kuya e henhla, ku tsana ka bond yale ndzeni), pinholes/blisters (moya lowu khomiweke kumbe steam), swivati swo basa na chalking (ku rhurha ka surfactant kumbe incomplete fusion), ku yellow/coking (ku hisa ngopfu ka swiengeteri), delamination (shrinkage stress exceeds adhesion), orange peel (ku nga ringani kahle), warpage (ku hunguteka loku nga ringaniki), ku oma ehenhla kambe endzeni ku tsakama (ku khuluka ka nhlonge swi khoma ndzhongho), na matlhelo yo tiya (coffee-ring effect). Switshuxo swikatsa ti drying profiles leti lawuriwaka, ku nghenisiwa ka moya kahle, na substrate pretreatment.

Xivumbeko xa xikandza xa makumu lexi tsemiweke xa thepi ya mahiselo yale henhla ya PTFE xi khumba hiku kongoma ku khuluka ka adhesive na ku tlakuka ka makumu hi nkarhi wa ku cheriwa. Ku tshoveka lokunga kahle (dull blades, improper angle) swiendla ti glue filaments, swi olovisa edge adhesive layer, naswona swi paluxa ti fiberglass burrs – leswi yisaka eka oozing, weak bonding, naku tlakusa ehansi ka kuhisa kumbe tension. Swikandza swa makumu leswinga tshamisekangiki (wavy, protruding) swivanga ku hangalasiwa ka ntshikelelo lokunga ringaniki, leswi fambisaka adhesive creep hinkarhi wa nhlayiso. Xikandza xa kahle xa makumu xa rhetela, xa flush, naswona axi onhaki – xitirha tani hi seal leyi khiyaka adhesive naswona yitiyisisa ku hlanganisiwa ka matlhelo hinkwawo.

PTFE emulsion impregnation ya fiberglass fabric yilava swipfuneti swohambana hambana kuva ku fikeleriwa ku peta loku fanaka, ku namarhela loku tiyeke, na swiphemu leswinga riki na swihoxo. Swiengeteri swa nkoka swikatsa: switirhisiwa swo tsakamisa (ku hunguta ku tsana ka le henhla, ku antswisa ku nghena), swithickeners (ku lawula viscosity na ntiko wa ku peta), swilawuri swa pH (ku tiyisisa emulsion eka pH 9-10), switirhisiwa swo hlanganisa swa silane (ku ndlandlamuxa ku namarhela eka nghilazi), swipfuneti swo vumba filimi (PFA/FEP ku sintering), ti fillers leti tirhaka (ku lwisana na ku ambala, ku fambisa), ti defoamers (ku sivela ti pinholes), na ti humectants (ku oma hiku nonoka). Ku hlawuriwa swiya hi swilaveko swa substrate na matirhelo.

Hi nkarhi wa PTFE tape coating, solvent volatilization rate ya silicone pressure-sensitive adhesive i parameter ya nkoka ya maendlelo. Hiku hatlisa swinene → ku khuluka ka nhlonge yale henhla, ku nga ringani kahle, ti pinholes (trapped solvent), na ti craters (condensation kumbe contaminant-induced). Ku nonoka ngopfu → ku rhetela, matlhelo yo tiya, na ku dewetting eka PTFE ya eneji ya le hansi ya le henhla. Qhinga lerinene: ku nonoka ka volatilization yosungula kuva yi levela xikan’we naku baleka ka bubble, kutani ku hatlisisiwa ku omisiwa kuva yi vumba. Tirhisa ti solvents leti pfanganisiweke (toluene/xylene + fast-drying) na mahiselo ya oven ya gradient (yale hansi→xikarhi→le henhla).
