Ku hunguteka ka ku hisa ka lapi ra fiberglass i xivangelo lexikulu xa ku nga tshamiseki ka dimensional ya PTFE tape. Eka mahiselo ya PTFE sintering (360-400°C), ntshikelelo wa ku luka lowu saleke wa humesiwa. Loko yi nga siveriwi, lapi ra hunguteka; loko yi siveriwa, ntshikelelo lowu fihliweke wu pfaleriwile, leswi endlaka leswaku endzhaku ka nkarhi ku hunguteka hi nkarhi wa ku horisiwa hi adhesive (150-200°C) na ku hisa ka matirhiselo yo hetelela. Ntlhantlho: tirhisa pre-heat-set fiberglass leyingana <0.5% shrinkage eka 400°C, ku herisa ntshikelelo lowu saleke loko unga se peta.

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.

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.

Vutshunguri bya le henhla bya PTFE eka ku namarhela ka bonding byi tirhisa tindlela timbirhi letikulu: ku n’oka ka mahiselo yale henhla (ku tiya ka maxelo yale henhla, matimba ya 9.5 MPa na coupling agent, kambe yi humesa tigasi letingana chefu) na sodium-naphthalene etching (5 MPa ku namarhela hiku hatlisa, fasitere ro koma ra 24-48 wa tiawara, thyaka leri nga na khombo). Hlawula kuya hi vulawuri bya mbango na matirhelo ya nkarhi woleha vs. ya nkarhi wo koma.

Ku kamberiwa ka khwalithi ya emulsion ya PTFE swikatsa swikombiso swa nkoka swa tsevu: nhlayo ya solid (60±2% hi T/FSI 067-2021), pH (9.0-11.0), ku hangalasiwa ka vukulu bya ti particle (laser diffraction/DLS), viscosity (12-30 mPa·s eka 25°C), kutshamiseka (centrifugal, thermal, freeze-thaw), na xivumbeko. Nkongomiso lowu wu katsa tindlela ta xikambelo xa ntolovelo eka parameter yin’wana na yin’wana.

Ku chela thepi ya mahiselo yale henhla ya PTFE hiku tiya eka swiphemu leswi govekeke na leswinga tshamisekangiki handle ka swiphemuphemu na ku soholotiwa ka makumu, endlelo ra matirhelo leri ringaniseriweke i ra nkoka, kukatsa na vutshunguri bya substrate lebyi heleleke, vuswikoti byo chela bya xiphurofexinali na magoza ya kahle yo pfuneta. Exikarhi ka swona, substrate pretreatment i goza ra nkoka swinene, leri vekaka kwalomu ka 70% wa mbuyelo wohetelela wo namarhela.

Eka xiyimo xa milawu ya mbango leyi yaka yi tika, PFOS/PFOA-free PTFE emulsion i xitirhisiwa lexi ndlandlamuxiweke lexi tumbuluxiweke ku siva maendlelo ya ndhavuko ya polymerization lawa yanga na PFOA. Yi hlayisa swihlawulekisi swa nkoka swa PTFE loko yi ri karhi yi ndlandlamuxa swinene vunghana bya mbango na vuhlayiseki bya rihanyo.

Xiringaniso xa ku andzisiwa ka mahiselo ya lapi ra mahiselo yale henhla ya PTFE ahi nhlayo leyi nga cinciki. Yitshama yiri ehansi swinene eka mahiselo ya kamara kuya eka 100°C (kwalomu ka 0.5×10−5/°C), hambiswiritano yi tlakuka swinene ehansi ka swiyimo swa mahiselo yale henhla.

Tanihi muendli wa xiphurofexinali wa lapi ra mahiselo ya le henhla ya PTFE, Jiangsu Aokai New Materials yi avelana tindlela ta nkoka to tsemeta. Ku papalata ti burrs, delamination na dimensional deviation hinkarhi wa slitting, i swa nkoka ku lawula hindlela ya maendlelo ya mune wa ti core elements: switirhisiwa swo tsema, switirhisiwa, switirhisiwa swoka swinga tirhisiwanga an

Tanihi muendli wo sungula wa tithepi ta mahiselo ya le henhla ya PTFE, Jiangsu Aokai New Materials hi laha yi andlala vuyelo bya tindlela to kufumeta na mimpimo yo kufumeta eka matirhelo ya tithepi ta mahiselo ya le henhla ya PTFE leti horisiweke.I.
