Ungazigwema Kanjani Izinkinga Ezidalwa Ukwanda Okushisayo ku-PTFE High-Temperature Fabric Applications

Indwangu ye-PTFE enezinga eliphezulu lokushisa ayinayo i-coefficient egxilile ye-thermal expansion (CTE). Ngokungafani nensimbi noma ipulasitiki eqinile, ukuziphatha kwayo okunwetshiwe kuthintwa ngokuhlanganyela indwangu yesisekelo se-fiberglass, okuqukethwe kokulayisha kwe-PTFE, ukwakheka kokweluka, nobubanzi bokushisa obusebenzayo.

Le nkimbinkimbi ivamise ukuholela ezinkingeni ezingalindelekile: amabhande okuthutha aboshwe ngamabhande, ama-gasket adabukile, izendlalelo ezincishisiwe, noma olayini abakhiphayo abasontekile. Ukuqonda nokuklama ukunwetshwa okushisayo kubalulekile ekusebenzeni okuthembekile kwesikhathi eside.

I-Aokai PTFE ihlaziye ukuziphatha kokwandisa okushisayo kuzo zonke izinhlelo zokusebenza. Lo mhlahlandlela uchaza amanani ajwayelekile e-CTE futhi unikeza izixazululo eziyisithupha ezisebenzayo zokugwema ukwehluleka okuhlobene nokwanda.

Ama-Coefficients Ajwayelekile Okwandisa Okushisayo - Yazi Izinombolo Zakho

1. I-PTFE eyinkomba ehlanzekile ye-CTE

I-PTFE ehlanzekile ine-coefficient ephezulu yomugqa yokunweba okushisayo: cishe 10×10⁻⁵ – 20×10⁻⁵/°C (100–200 ppm/°C) kuzinga lokushisa legumbi, ngokuhluka okungewona umugqa njengokushintsha kwezinga lokushisa.

Inothi elibalulekile: I-PTFE idlula kunguquko yesigaba secrystalline cishe ku -19°C no-30°C , okuholela ekushintsheni kwevolumu okungazelelwe okungu- 1%–2% . Lesi sici sidinga ukunakwa okukhethekile kwezinhlelo zokusebenza ezinembayo. Ifilimu ye-PTFE engamamitha angu-1 ubude ingakhula ngo-1-2 cm ngokumane idlule ekamelweni lokushisa.

2. Indwangu ye-PTFE ephezulu yokushisa (i-fiberglass substrate) - ububanzi obujwayelekile be-CTE

I-Fiberglass ngokwayo ine-CTE ephansi kakhulu ye-approx. 5×10⁻⁶/°C (5 ppm/°C) , esebenza njengohlaka oluqinile lokukhawulela ukunwetshwa kwe-PTFE nokunciphisa kakhulu ukunwetshwa okushisayo okungaphakathi kwendiza kwendwangu eqediwe. Kodwa-ke, isakhiwo esilukiweyo sisaholela ekwandeni okuphezulu kunendwangu ye-fiberglass engenalutho.

Ukunwetshwa eduze kogqinsi kubaluleke kakhulu ngenxa yengxenye ephezulu ye-PTFE resin. Ngezinjongo zobunjiniyela, izinguquko zobukhulu bendiza kuphela ezivame ukubekwa kuqala.

Dizayina Ukucaciswa Kwesakhiwo Kokwelulwa Kwe-Thermal

1. Imiphetho yokwandisa yamahhala

Uma isetshenziswa njengama-gaskets, omati be-thermal insulation, noma izindawo ezishelelayo, gwema ukulungiswa okugcwele kuzo zonke izinhlangothi ezine. Bhuka okungenani umphetho wamahhala owodwa noma emibili ukuze uvumele ukunwebeka nokufinyela okushisayo okungakhawulelwe.

2. Izimbobo ezifakwayo ezinde

Uma kudingeka ukuboshelwa kwebhawodi, nweba izimbobo noma usebenzise izimbobo ezinde eziboshiwe. Ungawaqinisi ngokugcwele amabhawodi; engeza ama-gaskets ukuze ugcine isabelo sokuslayida esincane. Lokhu kuvumela okokusebenza ukuthi kunwetshwe futhi kunciphe ngaphandle kokugxilisa ingcindezi kumaphoyinti ebhawodi.

3. Ukubeka ngokwezigaba

Ukuze kufakwe indawo enkulu, hlukanisa indwangu ibe ngamaphaneli ahlukene anamajoyinti anwebekayo angu-3-5 mm phakathi kwezicucu, ikakhulukazi ngobude. Lokhu kuvimbela ukunqwabelana ekukhuleni okwandayo kuzo zonke izikhala ezide.

Gwema Ukuhamba Ngebhayisikili Okushisayo Okusheshayo Esigabeni Sokushintshwa Kwamazinga Okushisa Abalulekile

I-PTFE ihlushwa ukuguquguquka okukhulu kwevolumu eduze nezinga lokushisa legumbi – ikakhulukazi ku- 19°C kanye no-30°C amaphuzu wesigaba soshintsho. Uma okokusebenza kujwayele ukushintshana phakathi kwesitoreji esibandayo nezinga lokushisa le-ambient, ungayiqinisi indwangu ye-PTFE iqine kakhulu.

• Uma ifakwe ekushiseni okuphansi kodwa isebenza ngaphansi kokushisa okuphezulu, indwangu izonwebeka (isb., indwangu eyimitha engu-1 yelula amamilimitha ambalwa uma ishisisa ukusuka ku-25 ° C kuya ku-200 ° C).

• Hlomisa ama-tensioning asembling ngesinxephezelo esizenzakalelayo (amasistimu alayishwe intwasahlobo noma ama-counterweight) esikhundleni sokukhiya okuqinile.

Umthetho obalulekile: Ungalokothi ucindezele indwangu ye-PTFE iqine ekamelweni lokushisa bese uyifudumeza - ukunwetshwa kuzodala ama-ripples. Ungalokothi uyiqinise kakhulu ekushiseni okuphezulu bese uyipholisa - ukushwabana kuzoklebhula noma kucindezele kakhulu okokusebenza.

Idizayini Ye-Anti-Buckling Yokugqagqana Namalunga

• Hambana eduze kwesikhombisi-ndlela sokunweba , futhi uqinisekise ukuthi ububanzi obugqagqene budlula ubude obubikezelwe obukhulu.

• Ukuze uthole ama-seams athungiwe , shiya imvume evulekile emiculweni yokuthunga. Uma ihlanganiswe ne-adhesive enezinga eliphezulu lokushisa, khetha iglue enwebekayo ukuze uvimbele ukudabuka okubangelwa ama-coefficients okunweba angafani.

• Ngokunqwabelana kwezendlalelo eziningi , gwema ukubopha okugcwele ebusweni. Adopt spot bonding noma ukulungisa ukwahlukanisa ngemichilo yokunyathelisa ukuze uvumele ukushelela kwe-interlayer - ukususa amabhamuza nokuqhekeka.

Ukulawula Ukuqina Kwezimo Zokusebenza

1. Izinhlelo zokusebenza zebhande le-Conveyor

Faka i-counterweight noma i-spring-loaded automatic tensioner ukuze umunce ukukhululeka kwendwangu emazingeni okushisa aphezulu futhi inciphe emazingeni okushisa aphansi. Ungalokothi uqinise kakhulu ibhande ngaphansi kokushisa okuphezulu - lokhu kuzodala ukugcwala kakhulu ngesikhathi sokufinyela okubandayo. Ukuqina kwebhande kufanele kusethwe ezingeni lokushisa eliphansi elilindelekile lokusebenza.

2. Khipha ama-liner namashidi okuhlukanisa

Lala phansi ngaphandle kwe-pre-tension. Vikela kancane ngesisindo sakho noma imichilo yokucindezela emincane endaweni eyodwa ukuze uvimbele ama-creases angunaphakade okubangwa ukunwetshwa okushisayo.

Nciphisa Ukuhlanekezela Kusuka Kumazinga Okushisa Amandla Kakhulu

Ukunwetshwa okungalingani kwenzeka lapho uhlangothi olulodwa lwendwangu luchayeka ekushiseni okuphezulu kuyilapho olunye luhlala lupholile, okubangela ukungqubuzana.

Izinyathelo zokulungisa:

• Ukubamba ngezikhathi ezithile ngozimele esikhundleni sokuminyanisa okuqhubekayo komphetho ogcwele

• Khetha indwangu eyisisekelo ye-fiberglass ewugqinsi, enokuminyana okuphezulu kakhulu ukuze unciphise i-warpage

• Setha kusengaphambili i-arching ehlanekezela ohlangothini lwezinga lokushisa eliphansi uma kunesidingo (goba ngaphambili indwangu ukuze ilingane ezingeni lokushisa lokusebenza)

Ukuhlolwa Kwezikhathi kanye Nokunakekela

Ngemuva kokuhamba ngebhayisikili okushisayo kwesikhathi eside, i-PTFE izothola ukuwohloka kokugeleza okubandayo , okuholela ebudeni obungapheli bobude noma ukuntenga kwendawo.

• Hlola njalo futhi ulungise amazinga we-tension - amabhande angase adinge ukucindezelwa kabusha ngemva kwemijikelezo embalwa yokuqala yokushisa.

• Lungisa amaqhuqhuva kanye ne-delamination ngokushesha ukuze ugweme ukugxila kwengcindezi nokuklebhuka.

• Ukuziphatha kokukhulisa idokhumenti - uma ibhande lihlala linwebeka ngaphezu kwebanga lokulungiswa, lingase lidinge ukushintshwa noma i-substrate ehlukile efana ne-CTE.

Isincomo se-Aokai PTFE: Kuzinhlelo zokusebenza ezinokuhamba ngebhayisikili okushisayo okwedlulele (isb., amaconveyors kahhavini ahamba ngebhayisikili ukusuka ku-ambient kuye ku-250°C izikhathi eziningi ngosuku), sincoma indwangu enokuqukethwe okuphezulu kwe-fiberglass (i-CTE ephansi) kanye nokuqapha okuzenzakalelayo kokuqina.

Isifinyezo – Uhlu Lokuhlola Lomklamo Wokunwebeka Okushisayo

I-Aokai PTFE inikeza i-PTFE indwangu yezinga lokushisa eliphezulu enamanani abhaliwe e-CTE futhi ingancoma amamaki athile ebangeni lokushisa lohlelo lwakho lokusebenza. Xhumana nathi ukuze uthole amashidi edatha yezobuchwepheshe kanye nosekelo lomklamo wohlelo lokusebenza.

Lo mbhalo wobuchwepheshe uhlinzekwa ngu I-Jiangsu Aokai New Materials Technology Co., Ltd.

Uma udinga amapharamitha wezobuchwepheshe ajulile, amakesi okufaka isicelo kanye nezixazululo ezenziwe ngokwezifiso zephothifoliyo yethu yomkhiqizo ogcwele ohlanganisa izindwangu ze-PTFE ezishisa kakhulu, amakhasethi e-PTFE, amabhande anezikhala e-PTFE, amabhande e-laminator angenamthungo, indwangu ye-PTFE enohlangothi olulodwa kanye namabhande okuthutha angaphansi kwezinga lokushisa eliphezulu, sicela usithinte:

• UMnu. Guo: +86 18944819998

• UMnu. Liu: +86 13705266308

Sinamathela ezindinganisweni zobungcweti nobuqotho ukuze silethe izixazululo zezinto ezibonakalayo kanye nokwesekwa okucabangelayo kwangemva kokuthengisa kwawo wonke amaklayenti.
