Ndlela Yo Papalata Swiphiqo Leswi Vangiwaka Hi Ku Andzisiwa ka Ku Hisisa eka Switirhisiwa swa Lapi ra Mahiselo ya le Henhla ya PTFE

Lapi ra PTFE ra mahiselo yale henhla ari na fixed coefficient of thermal expansion (CTE). Kuhambana na nsimbi kumbe plastiki yo tiya, mahanyelo ya yona yo anama ya khumbeka hiku hlanganela hi fiberglass base fabric, PTFE loading content, weaving structure, na operating temperature range.

Ku rharhangana loku hakanyingi ku endla leswaku ku va ni swiphiqo leswi nga languteriwangiki: mabandhi yo fambisa lama bohiweke, ti- gasket leti handzukeke, swiphemu leswi nga ni swiphemu-phemu kumbe swirhendzevutana swo humesa swilo leswi soholotiweke. Ku twisisa naku dizayina ku ndlandlamuxiwa ka mahiselo swina nkoka eka matirhelo yo tshembheka ya nkarhi woleha.

Aokai PTFE yi kambisisile mahanyelo ya ku ndlandlamuxiwa ka mahiselo eka switirhisiwa swo tala. Nkongomiso lowu wu hlamusela mimpimo ya ntolovelo ya CTE naswona wu nyika swintshuxo swa tsevu leswi tirhaka ku papalata ku tsandzeka loku fambelanaka na ku ndlandlamuxiwa.

Tikhoyifisiyense leti Tolovelekeke ta ku Andzisiwa ka Ku Hisisa – Tiva Tinhlayo ta Wena

1. Pure PTFE xikombo xa CTE

Pure PTFE yina linear coefficient yale henhla ya thermal expansion: kwalomu ka 10×10−5 – 20×10−5/°C (100–200 ppm/°C) eka mahiselo ya kamara, laha kungana ku hambana lokunga linear loko mahiselo ya cinca.

Xitsundzuxo xa nkoka: PTFE yi hundza eka ku cinca ka xiphemu xa crystalline kwalomu ka 19°C na 30°C , leswi yisaka eka ku cinca ka volume hi xitshuketa ka 1%–2% . Xihlawulekisi lexi xi lava nyingiso wo hlawuleka eka switirhisiwa swa vukheta. Filimi ya PTFE yo basa yo leha 1-meter yinga kula hi 1-2 cm ntsena hiku hundza eka mahiselo ya kamara.

2. Lapi ra mahiselo yale henhla ya PTFE (fiberglass substrate) – nxaxamelo wa CTE lowu tolovelekeke

Fiberglass hi yoxe yina CTE yale hansi swinene ya kwalomu ka. 5×10−6/°C (5 ppm/°C) , leyi tirhaka tani hi rigid framework ku siveriwa ka PTFE expansion naku hunguta swinene in-plane thermal expansion ya lapi leri hetiweke. Hambiswiritano, xivumbeko lexi lukiweke xa ha endla leswaku ku va ni ku andza lokukulu ku tlula lapi ra fiberglass leri nga riki na nchumu.

Ku ndlandlamuxiwa kuya hi tlhelo ra vukulu swina nkoka swinene hikokwalaho ka xiphemu xale henhla xa PTFE resin. Hi swikongomelo swa vunjhiniyara, i ku cinca ka dimensional in-plane ntsena loku hi ntolovelo ku rhangisaka emahlweni.

Dizayini ya Swivandla swa Xivumbeko swa ku Engetela ka ku Hisisa

1. Matlhelo yo ndlandlamuxa ya mahala

Loko u tirhisiwa tanihi ti- gasket, ti- thermal insulation mats kumbe swilo leswi rhetaka, papalata ku khomiwa hi ku helela ematlhelo hinkwawo ya mune. Hlayisa kwalomu ka matlhelo man’we kumbe mambirhi lawa ya ntshunxekeke kuva u pfumelela ku olovisiwa ka mahiselo lokunga siveleriwangiki naku hunguteka.

2. Tikhomba to veka leti leheke

Loko ku laveka ku bohiwa ka ti bolt, ndlandlamuxa timbobo kutani u amukela ti slotted long holes. U nga tiyisi swiboluti hi ku helela; engetela ti gaskets ku hlayisa mali leyintsongo yo rhetela. Leswi swipfumelela leswaku swilo swi andlala naku hunguteka handle ka stress concentration eka tindzhawu ta bolt.

3. Ku veka hi swiphemu-phemu

Eka ku vekiwa ka ndzhawu leyikulu, avanyisa lapi hi ti panels to hambana letingana 3–5 mm expansion joints exikarhi ka swiphemu, ngopfu ngopfu kuya hi tlhelo ro leha. Leswi swi sivela buckling kusuka eka cumulative expansion eka ti spans to leha.

Papalata Ku Cinca ka Thermal hi Xihatla Ku tsemakanya Mahiselo ya Nkoka ya Phase Transition

PTFE yi xaniseka hi ku cinca cinca lokukulu ka volume ekusuhi na mahiselo ya kamara – ngopfu ngopfu eka 19°C na 30°C phase transition points. Loko switirhisiwa switala ku cincana exikarhi ka vuhlayiselo byo titimela na mahiselo ya ndzhawu, unga tshikeli lapi ra PTFE swinene.

• Loko yi vekiwile eka mahiselo yale hansi kambe yitirhisiwile ehansi ka kuhisa lokukulu, lapi rita leha (xikombiso, lapi ra 1-meter ri anama ti millimeters to hlaya loko ri hisiwa kusuka eka 25°C kuya eka 200°C).

• Hlomisa ti tensioning assemblies hi automatic compensation (spring-loaded kumbe counterweight systems) ematshan’wini ya rigid locking.

Nawu wa nkoka: Unga tshuki u tshikelela lapi ra PTFE swinene eka mahiselo ya kamara kutani u ri hisa – ku ndlandlamuxiwa swita endla leswaku kuva na swirhabyani. Unga tshuki u yi tension swinene eka mahiselo yale henhla kutani u yi kufumeta – ku hunguteka swita handzula kumbe ku tshikilela ngopfu swilo leswi.

Dizayini ya Anti-Buckling ya Swiphepherhele na Swihlanganisi

• Overlap along the expansion direction , naswona tiyisisa leswaku ku anama loku hlanganisaka ku tlula ku leha lokukulu loku vhumbhiweke.

• For sewn seams , siya allowance leyi ntshunxekeke eka tintambhu to rhungela. Loko yi hlanganisiwa na xinamarheti xa mahiselo yale henhla, hlawula glue ya elastic ku sivela ku handzuka loku vangiwaka hi ti expansion coefficients letinga fambelaniki.

• For multi-layer stacking , papalata ku hlanganisiwa ka xivumbeko hinkwaxo. Amukela spot bonding kumbe partition fixing hi press strips kuva yi pfumelela interlayer sliding – ku herisa blistering na delamination.

Vulawuri bya Ntshikelelo wa Swiendlakalo swa Ntirho

1. Switirhisiwa swa conveyor belt

Nghenisa ti counterweight kumbe ti spring-loaded automatic tensioners kuva ti tswonga ku olova ka lapi eka mahiselo yale henhla xikan’we naku hunguteka eka mahiselo yale hansi. Unga tshuki u tiyisisa bandhi ngopfu ehansi ka kuhisa lokukulu – leswi swita endla leswaku kuva na ndzhwalo wo tlula mpimo hinkarhi wa ku hlangana ka xirhami. Ntshikelelo wa bandi wufanele ku vekiwa eka mahiselo yale hansi swinene lawa ya languteriweke ya ntirho.

2. Ntshunxa ti liners na ti isolation sheets

Lay flat handle ka pre-tension. Tiyisisa hiku olova hi ti self-weight kumbe ti press strips letintsongo eka tlhelo rin’we ku sivela ti permanent creases leti hlohleteriwaka hiku andzisiwa ka mahiselo.

Ku hunguta ku Soholotiwa kusuka eka Ti Gradients ta Mahiselo yo Tika

Ku anama loku nga ringaniki ku humelela loko tlhelo rin’we ra lapi ri hisa swinene kasi lerin’wana ri tshama ri ri karhi ri kufumela, leswi endlaka leswaku ku va ni ku soholota.

Magoza yo lulamisa: .

• Ku khomiwa hi nkarhi na nkarhi hi tifureme ematshan’wini ya ku tshikileriwa loku yaka emahlweni ka matlhelo hinkwawo

• Hlawula lapi ra le hansi ra fiberglass ro tiya, ra density yale henhla ku hunguta warpage

• Pre-set reverse arching eka tlhelo ra mahiselo yale hansi loko swilaveka (pre-curve lapi leswaku rita flatten eka mahiselo yo tirha)

Ku Kamberiwa na ku Hlayisa Nkarhi na Nkarhi

Endzhaku ka nkarhi woleha wa thermal cycling, PTFE yita kuma cold flow deformation , leswi endlaka leswaku kuva na permanent dimensional elongation kumbe localized slackness.

• Nkarhi na nkarhi kambela naku lulamisa ti levele ta tension – mabandhi yanga lava ku tlhela u tensioniwa endzhaku ka swirhendzevutani swosungula swa thermal.

• Lulamisa ti bulges na delamination hiku hatlisa ku papalata stress concentration xikan’we naku handzuka.

• Mahanyelo ya ku ndlandlamuxiwa ka matsalwa – loko bandi ri tshama ri ri karhi ri ololoka ku tlula mpimo wa ku lulamisiwa, ri nga ha lava ku cinciwa kumbe substrate yo hambana ya CTE-matching.

Xitsundzuxo xa Aokai PTFE: Eka switirhisiwa leswingana ku rhendzeleka ka mahiselo yotala swinene (xikombiso, ti oven conveyors leti rhendzelekaka kusuka eka ambient kuya eka 250°C minkarhi yotala hi siku), hi ringanyeta lapi leringana nhlayo yale henhla ya fiberglass (CTE yale hansi) xikan’we naku langutisisa tension ya otomatiki.

Nkatsakanyo – Nxaxamelo wa Dizayini ya ku Andzisiwa ka ku Hisisa

Aokai PTFE yi nyika lapi ra mahiselo yale henhla ra PTFE leri nga na mimpimo ya CTE leyi tsariweke naswona yi nga ringanyeta tigiredi to karhi eka mpimo wa mahiselo ya wena ya xitirhisiwa. Tihlanganisi na hina ku kuma maphepha ya datha ya xithekiniki na nseketelo wa dizayini ya matirhiselo.

Tsalwa leri ra xithekiniki ri nyikiwile hi Jiangsu Aokai Switirhisiwa Leswintshwa Thekinoloji Co., Ltd.

Loko u lava tipharamitha ta xithekiniki leti dzikeke, timhaka ta swikombelo na swintshuxo leswi endleriweke photifoliyo ya hina leyi heleleke ya swikumiwa ku katsa na malapi ya mahiselo ya le henhla ya PTFE, tithepi ta mahiselo ya le henhla ya PTFE, mabandhi ya mesh ya PTFE, mabandhi ya laminator lama nga riki na swirhabyani, lapi ra PTFE ra tlhelo rin’we na mabandhi yo fambisa lama lwisanaka na mahiselo ya le henhla, hi kombela u hi tihlanganisa hi ku tirhisa tichanele leti nga laha hansi:

• Nkulukumba Guo: +86 18944819998

• Nkulukumba Liu: +86 13705266308

Hi namarhela swiyimo swa xiphurofexinali na vutshembeki ku tisa swintshuxo swa switirhisiwa swa xiyimo xin’we na nseketelo wa le ndzhaku ka ku xavisiwa lowu anakanyisisiweke eka tikhayente hinkwato.
