Isebenza kanjani i-PTFE kanye ne-Glass Fiber Bond Ngaphandle Kwe-Delamination Ngaphandle Kwamabhondi Amakhemikhali?

I-Jiangsu Aokai New Materials, umkhiqizi ohamba phambili wezindwangu ze-PTFE ezishisa kakhulu, uyachaza:

I-Polytetrafluoroethylene (PTFE) ne-glass fiber (ikakhulukazi eyakhiwe nge-silica) ayikwazi ukwakha izibopho zamakhemikhali. I-PTFE inamandla angaphezulu aphansi kakhulu (acishe abe ngu-18 mN/m), aziwa 'i-non-stick coating', kuyilapho i-glass fiber iyi-hydrophilic polar inorganic material. Zombili azihambisani ngokwemvelo.

Kwa-Aokai, simithisa indwangu ye-fiber yengilazi nge-emulsion ye-PTFE, ikakhulukazi ngezindlela ezilandelayo:Nakuba i-PTFE ngokwayo inzima ukuyibopha, i-ejenti ehlanganisayo (njenge-silane) ingasetshenziswa ukwakha ibhuloho endaweni ye-fiber yengilazi. Umgomo uthi: Ingaphezulu le-fiber yengilazi limbozwe nge-ejenti yokuhlanganisa i-silane. Omunye umkhawulo we-silane (iqembu le-alkoxy) uthola ukusabela kwe-condensation namaqembu e-silanol (Si-OH) ku-fiber yengilazi ukuze enze izibopho zamakhemikhali; esinye isiphetho (njengeqembu le-amino, iqembu le-epoxy) liyasebenza.

Uma i-PTFE ngokwayo ingelashwa, isiphetho esisebenzayo se-ejenti yokuhlanganisa ayikwazi ukuhlangana ne-PTFE, ngakho ukwelashwa okungaphezulu kuyadingeka. Umkhuba ojwayelekile ukungeza ama-coupling agents kanye nezibophezelo ze-polymer (ezifana ne-PFA, FEP — perfluoroalkoxy resin noma i-tetrafluoroethylene-hexafluoropropylene copolymer, okuyi-fluoroplastics ecutshungulwayo encibilika) ku-emulsion ye-PTFE.

Isendlalelo soshintsho : I-Perfluoroalkoxy resin noma i-tetrafluoroethylene-hexafluoropropylene copolymer isetshenziswa njengesendlalelo esimaphakathi. Lawa ma-fluoroplastics anokuhambisana okuhle kwamakhemikhali ne-PTFE, angancibilika futhi ageleze ezingeni lokushisa eliphansi, abophe i-silane-treated glass fiber nge-PTFE ngobuningi, enze isixhumi esibonakalayo se-gradient, futhi asuse ukuguqulwa kokucindezeleka.

Ukuhlangana phakathi kwe-PTFE ne-glass fibre empeleni kuyinhlanganisela engokwenyama yokuxhumanisa ngomshini + ukucindezelwa kwengcindezi + ungqimba wokuguquka kwegradient..

Ulwazi olungenhla lunikezwe i-Jiangsu Aokai New Materials Technology Co., Ltd.

Ukuze uthole imingcele enemininingwane, izimo zohlelo lokusebenza nezixazululo ezenziwe ngokwezifiso zohlu lwethu olugcwele lomkhiqizo - kufaka phakathi indwangu ye-PTFE yokushisa ephezulu, i-PTFE itheyiphu yokushisa ephezulu, ibhande le-PTFE elinezinga eliphezulu lokushisa, ibhande elingenamthungo lomshini wokubopha, indwangu ye-PTFE enohlangothi olulodwa, ibhande lokudlulisela elikwazi ukumelana nokushisa okuphezulu kanye neminye imikhiqizo ye-fiber engamelana nokushisa, sicela usithinte.
