Nigute wakwirinda ibibazo biterwa no kwaguka k'ubushyuhe muri PTFE Imyenda Yubushyuhe Bwinshi

Imyenda ya PTFE yubushyuhe bwo hejuru ntabwo ifite coefficient ihamye yo kwagura ubushyuhe (CTE). Bitandukanye nicyuma cyangwa plastiki ikomeye, imyitwarire yo kwaguka igira ingaruka hamwe nigitambara cya fiberglass base, PTFE yikuramo ibintu, imiterere yububoshyi, hamwe nubushyuhe bwo gukora.

Ibi bigoye akenshi biganisha kubibazo bitunguranye: imikandara ya convoyeur, imishwaro yatanyaguwe, ibice byangiritse, cyangwa imirongo yo kurekura. Gusobanukirwa no gushushanya kwagura ubushyuhe nibyingenzi mubikorwa byizewe byigihe kirekire.

Aokai PTFE yasesenguye imyitwarire yo kwagura ubushyuhe mubisabwa byinshi. Aka gatabo gasobanura indangagaciro za CTE kandi gatanga ibisubizo bitandatu bifatika kugirango wirinde kwaguka bijyanye no kwaguka.

Coefficients zisanzwe zo Kwagura Ubushyuhe - Menya Umubare wawe

1. CTF yerekana neza CTE

PTFE isukuye ifite coeffisiyeti ndende yo kwagura ubushyuhe: hafi 10 × 10⁻⁵ - 20 × 10⁻⁵ / ° C (100-200 ppm / ° C) ku bushyuhe bwicyumba, hamwe nuburyo butandukanye butandukanijwe nubushyuhe.

Icyitonderwa: PTFE ihura na kristaline yicyiciro cya 19 ° C na 30 ° C , bigatuma ihinduka ritunguranye rya 1% –2% . Ibiranga bisaba kwitabwaho bidasanzwe kubisobanuro byuzuye. Filime ifite uburebure bwa metero 1 ya PTFE irashobora gukura kuri cm 1-2 gusa unyuze mubushyuhe bwicyumba.

2. PTFE imyenda yubushyuhe bwo hejuru (fiberglass substrate) - urwego rusanzwe rwa CTE

Fiberglass ubwayo ifite ultra-low CTE ya hafi. 5 × 10⁻⁶ / ° C (5 ppm / ° C) , nk'urwego rukomeye rwo kugabanya kwaguka kwa PTFE no kugabanya cyane kwaguka mu ndege kwaguka kwimyenda yuzuye. Nyamara, imiterere yububoshyi iracyavamo kwaguka cyane kuruta umwenda wa fiberglass.

Kwaguka mubyerekezo byubugari nibyingenzi cyane kubera igipimo kinini cya resin ya PTFE. Kubikorwa byubwubatsi, gusa mu ndege ibipimo byimpinduka muri rusange.

Igishushanyo mbonera cyuburyo bwo Kongera Ubushyuhe

1. Impande zo kwaguka kubuntu

Iyo ukoresheje gasketi, materi yo kubika ubushyuhe, cyangwa kunyerera hejuru, irinde gukosorwa byuzuye kumpande enye. Bika byibuze kimwe cyangwa bibiri byubusa kugirango wemererwe kurambura ubushyuhe no kugabanuka.

2. Umwobo muremure

Niba gufunga bolt bisabwa, wagura umwobo cyangwa ufate umwobo muremure. Ntugahambire byimazeyo; ongeramo gasketi kugirango ubike amafaranga yo kunyerera. Ibi bituma ibikoresho byaguka kandi bikagabanuka nta guhangayikishwa cyane na point ya bolt.

3. Gushyira ibice

Kugirango ushyire ahantu hanini, gabanya umwenda mubice bitandukanye hamwe na mm 3-5 zo kwaguka hagati yibice, cyane cyane mubyerekezo birebire. Ibi birinda guhuzagurika kwaguka mugihe kirekire.

Irinde Amagare Yihuta Yumukino Kurenga Icyiciro Cyinzibacyuho Ubushyuhe bukomeye

PTFE ihura ryinshi ryubushyuhe bwicyumba - cyane cyane kuri 19 ° C na 30 ° C. nihindagurika Niba ibikoresho bigenda bisimburana hagati yububiko bukonje nubushyuhe bwibidukikije, ntugahagarike umwenda wa PTFE cyane.

• Iyo ushyizwe mubushyuhe buke nyamara ikorerwa munsi yubushyuhe bwinshi, umwenda uzaramba (urugero, umwenda wa metero 1 urambura milimetero nyinshi iyo ushyushye kuva kuri 25 ° C kugeza kuri 200 ° C).

• Shira inteko itera impagarara hamwe nindishyi zikora (sisitemu yuzuye cyangwa sisitemu iremereye) aho gufunga bikomeye.

Amategeko akomeye: Ntukigere uhagarika imyenda ya PTFE cyane mubushyuhe bwicyumba hanyuma uyishyuhe - kwaguka bizatera impagarara. Ntuzigere uyihagarika cyane ku bushyuhe bwo hejuru hanyuma ukonje - kugabanuka bizashwanyaguza cyangwa birenze ibikoresho.

Kurwanya Kurwanya Igishushanyo cyo guhuzagurika no guhuza

• Kuzenguruka ku cyerekezo cyo kwaguka , kandi urebe ko ubugari burenze burenze uburebure bwahanuwe.

• Kubudozi budoda , usige amafaranga arekuye kumudozi. Niba uhujwe nubushyuhe bwo hejuru, hitamo kole ya elastique kugirango wirinde kurira biterwa na coefficient yo kwaguka idahuye.

• Kubirindiro byinshi , irinde guhuza byuzuye. Emera guhuza ibibanza cyangwa ibice bikosorwa hamwe nibice byamakuru kugirango wemererwe kunyerera - gukuraho ibisebe no gusiba.

Kugenzura Umujinya Kubikorwa

1. Gukoresha umukandara

Shyiramo uburemere buremereye cyangwa amasoko yuzuye yimashini kugirango ukureho imyenda kuruhuka rwinshi no kugabanuka kubushyuhe buke. Ntuzigere uhambira umukandara munsi yubushyuhe bwinshi - ibi bizatera uburemere burenze mugihe cyo gukonja. Umuvuduko wumukandara ugomba gushyirwaho ubushyuhe buke buteganijwe.

2. Kurekura imirongo hamwe nimpapuro zo kwigunga

Shyira hasi nta pre-tension. Umutekano byoroheje ukoresheje uburemere-buke cyangwa imirongo migari ikanda mucyerekezo kimwe kugirango wirinde ibimera bihoraho biterwa no kwaguka k'ubushyuhe.

Kugabanya Kugoreka Biturutse kuri Ubushyuhe bukabije

Kwaguka kutaringaniye bibaho mugihe uruhande rumwe rwigitambara rwerekanwe nubushyuhe bwinshi mugihe urundi rugumye rukonje, rutera kurwara.

Ingamba zo gukemura:

• Gufatanya rimwe na rimwe kumurongo aho gukomeza kwuzuza kwuzuye

• Hitamo umubyimba mwinshi, mwinshi-mwinshi wa fiberglass fatizo kugirango ugabanye intambara

• Banza ushyireho arching kuruhande rwubushyuhe buke nibiba ngombwa (banza ugabanye umwenda kugirango ube wubushyuhe bwo gukora)

Kugenzura Ibihe no Kubungabunga

Nyuma yigihe kirekire cyamagare yubushyuhe, PTFE izagira ihinduka ryimbeho ikonje , bivamo kuramba guhoraho cyangwa gutinda kwaho.

• Buri gihe ugenzure kandi uhindure urwego rwo guhagarika umutima - umukandara urashobora gusaba kongera guhagarika umutima nyuma yubushyuhe buke bwa mbere.

• Sana ibibyimba no gusiba vuba kugirango wirinde guhangayika no kurira.

• Imyitwarire yo kwagura inyandiko - niba umukandara uhora urambuye kurenza urugero, birashobora gukenera gusimburwa cyangwa ubundi buryo bwa CTE buhuye nubutaka.

Icyifuzo cya Aokai PTFE: Kubisabwa hamwe nu gusiganwa ku magare bikabije (urugero, imiyoboro ya feri itwara amagare kuva ibidukikije kugeza kuri 250 ° C inshuro nyinshi kumunsi), turasaba umwenda urimo fibre nini cyane (CTE yo hepfo) hamwe no gukurikirana impagarara zikora.

Incamake - Urutonde rwo Kwagura Ubushyuhe

Aokai PTFE itanga PTFE yubushyuhe bwo hejuru hamwe nimyenda ya CTE kandi irashobora gutanga amanota yihariye kubipimo by'ubushyuhe bwawe. Twandikire kumpapuro zamakuru ya tekiniki hamwe nubufasha bwo gushushanya.

Iyi nyandiko ya tekiniki itangwa na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba ukeneye ibipimo byimbitse bya tekiniki, imanza zikoreshwa hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye birimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, imikandara ya meshi ya PTFE, imikandara ya laminator idafite umwenda, umwenda umwe wa PTFE hamwe nu mukandara wa convoyeur wihuta, nyamuneka twandikire ukoresheje imiyoboro ikurikira:

• Bwana Guo: +86 18944819998

• Bwana Liu: +86 13705266308

Twubahiriza ibipimo byumwuga nubunyangamugayo kugirango dutange igisubizo kimwe cyibikoresho hamwe nibitekerezo nyuma yo kugurisha kubakiriya bose.
