Imiphumela Yezinga Lokupholisa ku-PTFE Tape

Njengomkhiqizi wangempela wamateyipu e-PTFE asezingeni eliphezulu, i-Jiangsu Aokai New Materials ngalokhu ichaza imithelela yezindlela zokupholisa kanye namazinga okupholisa ekusebenzeni kwamateyipu e-PTFE apholile.

I. Ingqikithi Yezici Ze-PTFE Crystallization kanye Nokulawulwa Kwezinga Lokupholisa

I-PTFE substrate yetheyiphu eselashiwe yokushisa okuphezulu ingeyepolymer eyingxenye yecrystalline, ecwebezela ngokushesha ngesikhathi sokupholisa ngemva kokucwiliswa. Empeleni, izinga lokupholisa liyipharamitha yenqubo eyinhloko yokulawula ukucwebezela kwetheyiphu yokushisa ephezulu ye-PTFE: ukupholisa kancane kuholela ekucwebezeleni okuphezulu, kuyilapho ukupholisa okusheshayo kubangela ubucwebe obuphansi.

II. Imithelela Yokupholisa Okunensa Kumatheyipu e-PTFE Amazinga Okushisa aphezulu

Umthelela Ekucindezelekeni Kwangaphakathi  Ukupholisa kancane kunganciphisa ngempumelelo ingcindezi esele eshisayo ngaphakathi kwetheyiphu. Uma itheyiphu ipholiswe ngokwemvelo ngaphakathi kwesithando somlilo, i-PTFE matrix kanye nohlaka lwamathambo e-glass fibre anesikhathi esanele sokulungisa umehluko wokuncipha ngokuphumula kweketango lamangqamuzana, ukugwema ukugxilisana kokucindezeleka kwendawo.

Inqubo eyamukelwa kabanzi iwukupholisa itheyiphu ngokwemvelo esithandweni ukuya ku-150-200℃ ngaphambi kokuyikhiphela ukupholisa umoya. Le nqubo yokupholisa kancane inciphisa ukucindezeleka kwangaphakathi ngokuphumelelayo futhi ivimbele ukumboza i-delamination nokuqhekeka.

Umthelela Ekuzinzeni Kwe-Dimensional  Ukupholisa kancane kuthuthukisa kakhulu ukuzinza kwe-dimensional. Ngesikhathi sokupholisa okunensayo, amaketanga e-PTFE amangqamuzana ahleleka abe yizinhlayiya zekristalu ezivamile ngokwanele, akhe ubucwebe obuphezulu kanye nezinhlamvu zekristalu ezithuthuke kahle, eziqinisekisa ubukhulu bokugcina obuzinzile.

Ukuncipha kokushisa okuncane kuzokwenzeka ngaphansi kwezinga lokushisa eliphezulu ekusetshenzisweni kwangempela, ngakho-ke kunconywa ukuthi ugcine u-1% -2% wemajini ngesikhathi sokufaka isicelo. Ukupholisa okunensayo kwenza ukushwabana okungaguquki ngokuwohloka okuncane kwensalela.

Umthelela Ekusebenzeni Okunamathelayo  Ukupholisa okunensayo kunemiphumela emibili endaweni yokunamathela. Ngakolunye uhlangothi, ivumela isendlalelo sokunamathisela ukuthi siqedele ukuxhumanisa nokukhululeka kwengcindezi ngokugcwele, kugcinwe amandla okubopha azinzile. Ngakolunye uhlangothi, icrystallinity ephakeme inyusa ukuqina kwendawo ye-PTFE substrate, okubangela ingcindezi egxilile kusixhumi esibonakalayo sokubopha ngaphansi kwamandla okuxebuka.

III. Imiphumela Yokupholisa Okusheshayo ku-PTFE High-temperature Tapes

     Umthelela Ekucindezelekeni Kwangaphakathi  Ukupholisa okusheshayo kuyimbangela eyinhloko yengcindezi yangaphakathi eyeqile. Ukucisha okuqondile ngemva kokucwilisa kudala umehluko omkhulu wokushisa phakathi kwe-PTFE matrix kanye nohlaka lwefayibha yengilazi, okukhiqiza ukucindezeleka kokuncipha okusheshayo futhi kwenza kalula imifantu emihle.

Ungqimba olungaphezulu luyancipha futhi lube lukhuni ngokushesha ngenkathi ungqimba lwangaphakathi luhlala lunwetshiwe, lwakha isimo sokucindezeleka esishisayo sokucindezeleka kwangaphandle nokucindezelwa kwangaphakathi, okubangela ngokuqondile ukuqhekeka kwe-tape.

Ukuthonya Ukuzinza Kwe-Dimensional  Ukupholisa Okusheshayo kushintsha ukuphakama kwekristalu kuya ekushiseni okuphansi futhi kunciphisa ukucwebezela ngesakhiwo sekristalu esingaphelele. Itheyiphu ihlala endaweni eyiqhwa engalingani ngemva kokucisha. I-crystallization yesibili kanye nokuncipha kwangemuva kungenzeka ngaphansi kwezinguquko ezizayo zezinga lokushisa, okuholela ekuchezukeni kancane kancane kohlangothi.

Umthelela Ekusebenzeni Okunamathelayo  Ukupholisa okusheshayo kuvimbela ukuxhumanisa okugcwele kwezendlalelo zokunamathela. Ingcina iqandisiwe ngaphambi kokwenza inethiwekhi ephelele exhumene, okuholela ekwehleni kwamandla okubopha kanye nokumelana nezinga lokushisa.

Ngaphansi kokuhamba ngebhayisikili okubandayo nokushisa okuphindaphindiwe, umehluko wokunwebeka okushisayo phakathi kwe-PTFE substrate kanye nongqimba olunamathelayo kukhiqiza ukucindezelwa kwe-interface, kusheshisa ukuguga kwe-adhesive kanye ne-debonding, futhi kwenza buthaka kakhulu ukuqina kwe-viscosity.

IV. Ukuqhathaniswa Kwezindlela Ezihlukene Zokupholisa

 

Ngokuvamile, ukupholisa okunensayo nokufanayo kuyisimiso esiyisisekelo sokwelashwa kwangemva kokuphulukiswa kwamateyipu e-PTFE ashisa kakhulu. Kunconywa ukuthi usebenzise ukupholisa kwemvelo esithandweni somlilo ngemva kokucwiliswa, futhi ukhiphe amateyipu ukuze upholise umoya ekamelweni lokushisa ngemva kokuba izinga lokushisa lehla ngaphansi kuka-150-200℃. Ukupholisa okungalingani ngesikhathi sokukhiqiza kuzodala ukuxega futhi ekugcineni konakalise ikhwalithi yomkhiqizo.

Okuqukethwe okungenhla kunikezwa ngu I-Jiangsu Aokai New Materials Technology Co., Ltd.

Uma ufuna ukwazi imingcele enemininingwane, izimo zohlelo lokusebenza kanye nezixazululo ezenziwe ngokwezifiso zemikhiqizo yethu yochungechunge olugcwele kufaka phakathi indwangu ye-PTFE yokushisa okuphezulu, i-PTFE high-temperature tape, ibhande le-mesh lokushisa eliphezulu le-PTFE, ibhande lomshini wokuhlanganisa elingenamthungo, indwangu ye-PTFE enohlangothi olulodwa, ibhande lokushisa eliphezulu elimelana nokushisa, sicela usithinte i-fiberglass.
