Sei PTFE uye Girazi Fiber Bond Pasina Delamination Pasina Kemikari Bond?

Jiangsu Aokai New Materials, mugadziri anotungamira wePTFE high-temperature machira, anotsanangura:

Polytetrafluoroethylene (PTFE) uye girazi fiber (kunyanya inoumbwa nesilica) haigoni kuumba kemikari zvisungo. PTFE ine simba rakanyanya kuderera (rinoda kusvika 18 mN/m), rinozivikanwa se 'non-stick coating', nepo girazi faibha iri hydrophilic polar inorganic material. Zviviri izvi hazvipindirane.

PaAokai, tinopfekedza girazi fiber jira ne PTFE emulsion, kunyanya kuburikidza nenzira dzinotevera:Kunyange zvazvo PTFE pachayo yakaoma kusungirirana, chisungo chekubatanidza (senge silane) chinogona kushandiswa kuvaka bhiriji pagirazi fiber pamusoro. Nheyo yacho ndeiyi: Girazi faibha pamusoro rakaputirwa ne silane coupling agent. Imwe mugumo we silane (alkoxy boka) inosangana nekugadzirisa condensation nemapoka e-silanol (Si-OH) pagirazi fiber kuti iite makemikari zvisungo; mumwe magumo (akadai seamino boka, epoxy boka) rinoshanda.

Kana PTFE pachayo isina kurapwa, iyo reactive kuguma kweiyo coupling agent haigone kubatana nePTFE, saka kurapwa kwepamusoro kunodiwa. Chiitiko chakajairika ndechekuwedzera coupling agents uye polymer binders (senge PFA, FEP - perfluoroalkoxy resin kana tetrafluoroethylene-hexafluoropropylene copolymer, ayo ari melt-processable fluoroplastics) muPTFE emulsion.

Transition layer : Perfluoroalkoxy resin kana tetrafluoroethylene-hexafluoropropylene copolymer inoshandiswa sechikamu chepakati. Aya mafluoroplastics ane makemikari akanaka anoenderana nePTFE, anogona kunyunguduka uye kuyerera pane tembiricha yakaderera, kubatanidza silane-yakagadziriswa girazi fiber ine yakawanda PTFE, kuumba gradient interface, uye kubvisa kusagadzikana mutation.

Kubatana pakati pePTFE negirazi faibha ndiko kusanganisa kwemuviri kwemakanika kupindirana + kudzvanya kwekumanikidza + gradient shanduko dhizaini..

Ruzivo rwuri pamusoro rwunopihwa neJiangsu Aokai New Materials Technology Co., Ltd.

Kuti uwane ruzivo rwakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere - zvinosanganisira PTFE yakakwirira-tembiricha tepi, PTFE yakakwirira-tembiricha tepi, PTFE yakakwirira-tembiricha mesh bhandi, seamless bhandi rekubatanidza muchina, single-sided PTFE jira, yakakwirira-tembiricha isingachinjiki bhandi rekutakura uye zvimwe zvigadzirwa zvinodzivirira - girazi
