Ukuncipha okushisayo kwendwangu ye-Fiberglass kuyimbangela eyinhloko ye-PTFE tape dimensional ukungasebenzi. Emazingeni okushisa e-PTFE sintering (360-400°C), ingcindezi yokwaluka eyinsalela iyakhululwa. Uma kungavinjelwa, indwangu iyancipha; uma kuvinjelwa, ukucindezeleka okucashile kukhiyiwe, okubangela ukuncipha kamuva ngesikhathi sokuphulukisa okunamathelayo (150-200°C) kanye nokushisa kokugcina. Isixazululo: sebenzisa i-fiberglass esethwe ngaphambi kokushisa ene-<0.5% shrinkage ku-400 ° C, esusa ukucindezeleka okusele ngaphambi kokumboza.

Ama-thickeners ku-emulsion ye-PTFE enza imisebenzi emine ebalulekile: ukumiswa kokumiswa (kuvimbela ukuhlaliswa kwezinhlayiya eziminyene ze-PTFE), ukuziphatha kwe-shear-thinning (i-viscosity ephezulu ekuphumuleni, ephansi ngaphansi kokuyaluza ukuze kuhlanganiswe kalula), ukulawula ukujula kokungena (ukulawula ukulayishwa kwe-resin endwangu ye-fiberglass), kanye nokufana kwefilimu (kuvimbela ukuqhekeka ngesikhathi somiswa). Isidingo esibalulekile: izingqimba kufanele zibole ngokuphelele ku-~380°C izinga lokushisa le-sintering, lishiye i-zero umlotha insalela ukuze kugcinwe ukuhlanzeka kokunamathela kanye nokufakwa kukagesi.

I-Aokai PTFE ikhiphe okokuqala ngohlelo lwayo oluphelele lomkhiqizo e-APFE Shanghai 2026 (Booth 6T602, Hall 6). Imikhiqizo efakiwe ihlanganisa amateyipu e-PTFE aqiniswe nge-fiberglass, amafilimu e-PTFE ahlanzekile, amamaki aphikisana ne-static, namabhande okuthutha asezingeni eliphezulu - amboza ukucubungula ukudla, i-PV lamination, amabhethri e-lithium, izinto zikagesi, nokupakishwa. Umbukiso uqhubeka kuze kube uJuni 26. Yonke imikhiqizo isekela ukucaciswa okungokwezifiso.

Ukwelashwa kwe-PTFE ebusweni bokunamathela kokubopha kusebenzisa izindlela ezimbili eziyinhloko: ukuncibilika kwezinga lokushisa eliphezulu (ukumelana nesimo sezulu esiphezulu, amandla angu-9.5 MPa ane-ejenti yokuhlanganisa, kodwa kukhishwa amagesi anobuthi) kanye ne-sodium-naphthalene etching (5 MPa ukunamathela ngokushesha, iwindi elincane lamahora angu-24-48, imfucuza eyingozi). Khetha ngokusekelwe ekulawuleni imvelo kanye nokusebenza kwesikhathi eside ngokumelene nokusebenza kwesikhathi esifushane.

Ukuhlola ikhwalithi ye-emulsion ye-PTFE ihlanganisa izinkomba eziyisithupha ezibalulekile: okuqukethwe okuqinile (60±2% i-T/FSI 067-2021 ngayinye), i-pH (9.0-11.0), ukusatshalaliswa kosayizi wezinhlayiyana (i-laser diffraction/DLS), i-viscosity (12-30 mPa·s ku-25°C), ukuzinza (i-centrifugal, ukubukeka kweqhwa, ukugqama kwe-thaw). Lo mhlahlandlela uhlanganisa izindlela zokuhlola ezijwayelekile zepharamitha ngayinye.

Ukuze usebenzise itheyiphu yokushisa ephezulu ye-PTFE ngokuqinile ezindaweni ezigobile nezingajwayelekile ngaphandle kwamabhamuza nokuguquguquka konqenqema, inqubo yokusebenza esezingeni ibalulekile, okuhlanganisa nokwelashwa kwe-substrate okuphelele, amakhono okusebenza ochwepheshe kanye nezinyathelo ezifanele zokusiza. Phakathi kwazo, ukwelashwa kwe-substrate kuyisinyathelo esibucayi kakhulu, esinquma cishe u-70% womphumela wokugcina wokunamathela.

Ngokumelene nokwasemuva kwemithetho eqinile yezemvelo, i-emulsion ye-PFOS/PFOA-free PTFE ingumkhiqizo othuthukisiwe othuthukisiwe ukuze ungene esikhundleni sezinqubo zendabuko ze-PFOA eziqukethe i-polymerization. Igcina izici eziyinhloko ze-PTFE kuyilapho ithuthukisa kakhulu ubungane bemvelo nokuphepha kwezempilo.

I-coefficient yokwandisa okushisayo yendwangu ye-PTFE yokushisa okuphezulu ayilona ivelu egxilile. Ihlala iphansi uma kuqhathaniswa nezinga lokushisa lasekamelweni ukuya ku-100°C (cishe u-0.5×10⁻⁵/°C), nokho ikhuphuka kakhulu ngaphansi kwezimo zokushisa eziphezulu.

Njengomkhiqizi ochwepheshe we-PTFE indwangu yokushisa okuphezulu, i-Jiangsu Aokai New Materials yabelana ngamasu okusika okuyisisekelo. Ukuze ugweme ama-burrs, i-delamination kanye nokuchezuka kobukhulu ngesikhathi sokusika, kubalulekile ukulawula ngokuhlelekile izakhi ezine ezibalulekile: amathuluzi okusika, okokusebenza, izinto zokusetshenziswa

Njengomkhiqizi wangempela wamakhasethi we-PTFE wamakhasethi okushisa aphezulu, i-Jiangsu Aokai New Materials ngalokhu ichaza imithelela yezindlela zokupholisa namazinga okupholisa ekusebenzeni kwamakhasethi e-PTFE apholile.I.
