Nigute PTFE na Fibre Fibre Bond idafite Delamination idafite imiti ya chimique?

Jiangsu Aokai Ibikoresho bishya, uyobora uruganda rukora imyenda ya PTFE yubushyuhe bwo hejuru, abisobanura:

Polytetrafluoroethylene (PTFE) na fibre y'ibirahure (bigizwe ahanini na silika) ntibishobora guhuza imiti. PTFE ifite ingufu zo hejuru cyane (hafi 18 mN / m), izwi nka 'idafite inkoni ', naho fibre yikirahure nikintu cya hydrophilique polar organic organique. Byombi ntibisanzwe.

Kuri Aokai, dusama inda ya fibre fibre hamwe na emulioni ya PTFE, cyane cyane muburyo bukurikira: Nubwo PTFE ubwayo igoye guhuza, umukozi uhuza (nka silane) arashobora gukoreshwa mukubaka ikiraro hejuru yikirahure. Ihame ni: Ubuso bwa fibre fibre yubatswe na agent ya silane. Impera imwe ya silane (itsinda rya alkoxy) ihura na reaction ya matsinda ya silanol (Si-OH) kuri fibre yikirahure kugirango ihuze imiti; iyindi mpera (nkitsinda rya amino, itsinda rya epoxy) irakora.

Niba PTFE ubwayo itavuwe, iherezo ryimikorere ya agent ntishobora guhuza na PTFE, bityo rero birakenewe kuvurwa hejuru. Imyitozo isanzwe ni ukongeramo imiti ihuza hamwe na polymer binders (nka PFA, FEP - perfluoroalkoxy resin cyangwa tetrafluoroethylene-hexafluoropropylene copolymer, ikaba ishobora gushonga-fluoroplastique) muri emulioni ya PTFE.

Inzibacyuho : Perfluoroalkoxy resin cyangwa tetrafluoroethylene-hexafluoropropylene copolymer ikoreshwa nkurwego rwagati. Iyi fluoroplastique ifite imiti ihuza neza na PTFE, irashobora gushonga no gutemba mubushyuhe buke, guhuza fibre y ibirahuri ivurwa na silane hamwe na PTFE nyinshi, ikora intera ikurikirana, kandi ikuraho ihinduka ryimiterere.

Guhuza hagati ya PTFE na fibre yibirahure mubyukuri ni uguhuza kumubiri guhuza imashini + guhagarika imihangayiko + icyiciro cyinzibacyuho.

Amakuru yavuzwe haruguru atangwa na Jiangsu Aokai ibikoresho bishya byikoranabuhanga Co, Ltd.

Kubisobanuro birambuye, ibintu byakoreshejwe hamwe nibisubizo byabigenewe byuzuye mubicuruzwa byacu byuzuye - harimo imyenda yubushyuhe bwo hejuru bwa PTFE, kaseti ya PTFE yubushyuhe bwo hejuru, umukandara wa PTFE ufite ubushyuhe bwo hejuru, umukandara utagira kashe kumashini ihuza, umwenda wa PTFE uruhande rumwe, umukandara wa convoyeur wihanganira ubushyuhe bwinshi, imyenda y'ibirahure irwanya ubushyuhe bwinshi nibindi bicuruzwa - nyamuneka twandikire:
