Mokhoa oa ho Qoba Mathata a Bakiloeng ke Katoloso ea Mocheso ho Likopo tsa Lesela la Mocheso o Phahameng oa PTFE

Lesela la mocheso o phahameng oa PTFE ha le na coefficient e tsitsitseng ea ho atolosa mocheso (CTE). Ho fapana le tšepe kapa polasetiki e tiileng, boitšoaro ba eona ba katoloso bo ama ka kopanelo ke lesela la fiberglass base, PTFE loading content, weaving structure, and operating range range.

Ho rarahana hona hangata ho lebisa mathateng a neng a sa lebelloa: mabanta a conveyor a koaletsoeng, likhase tse tabohileng, lilae tse delaminated, kapa lithapo tse sothehileng tse lokollang. Ho utloisisa le ho rala bakeng sa katoloso ea mocheso ho bohlokoa bakeng sa ts'ebetso e tšepahalang ea nako e telele.

Aokai PTFE e hlahlobile boitšoaro ba katoloso ea mocheso lits'ebetsong tse ngata. Tataiso ena e hlalosa litekanyetso tse tloaelehileng tsa CTE mme e fana ka litharollo tse tšeletseng tse sebetsang ho qoba liphoso tse amanang le katoloso.

Li-Coefficients tse Tloaelehileng tsa Katoloso ea Thermal - Tseba Linomoro Tsa Hao

1. CTE e hloekileng ea PTFE

PTFE e hloekileng e na le coefficient e phahameng ea mola oa katoloso ea mocheso: e ka bang 10×10⁻⁵ – 20×10⁻⁵/°C (100–200 ppm/°C) mocheso oa kamore, ka mefuta e sa tšoaneng ea mocheso.

Tlhokomeliso ea bohlokoa: PTFE e etsa liphetoho tsa crystalline phase ho pota 19 ° C le 30 ° C , e lebisang phetohong e sa lebelloang ea molumo oa 1% -2% . Tšobotsi ena e hloka tlhokomelo e khethehileng bakeng sa lisebelisoa tse nepahetseng. Filimi e hloekileng ea PTFE e bolelele ba limithara tse 1 e ka hola ka 1-2 cm ka ho feta mocheso oa kamore.

2. PTFE lesela la mocheso o phahameng oa mocheso (fiberglass substrate) - mefuta e tloaelehileng ea CTE

Fiberglass ka boeona e na le CTE e tlase haholo ea hoo e ka bang. 5×10⁻⁶/°C (5 ppm/°C) , e sebetsa e le moralo o thata oa ho thibela katoloso ea PTFE le ho fokotsa haholo katoloso ea mocheso oa sefofane se felileng. Leha ho le joalo, sebopeho se lohiloeng se ntse se fella ka katoloso e phahameng ho feta lesela le hlakileng la fiberglass.

Katoloso e mabapi le botenya e bohlokoa haholo ka lebaka la karolo e phahameng ea PTFE resin. Bakeng sa merero ea boenjineri, ke liphetoho tsa sebopeho sa sefofaneng feela tse tlang pele.

Litlhaloso tsa Moralo oa Sebopeho bakeng sa Elongation ea Thermal

1. Meeli ea katoloso ea mahala

Ha e sebelisoa e le li-gaskets, mete ea ho kenya mocheso oa mocheso, kapa libaka tse thellang, qoba ho tiisa ka ho feletseng mahlakoreng 'ohle a mane. Beha bonyane ntlha e le 'ngoe kapa tse peli tsa mahala ho lumella ho otlolla le ho honyela ho sa thibeloang ha mocheso.

2. Likoti tse kentsoeng tse telele

Haeba ho hlokahala ho tiisa liboutu, atolosa masoba kapa u nke masoba a malelele. U se ke ua tiisa ka ho feletseng liboutu; eketsa li-gaskets ho boloka chelete e nyane ea ho thella. Sena se lumella thepa hore e atolohe le ho konteraka ntle le khatello ea maikutlo lintlheng tsa bolt.

3. Ho beha ka likarolo

Bakeng sa ho kenya sebaka se seholo, arola lesela ka liphanele tse arohaneng tse nang le maqhama a ho atolosa a 3-5 mm pakeng tsa likotoana, haholo-holo ho latela tataiso ea bolelele. Sena se thibela ho hola ho tsoa katolosong ea nako e telele.

Qoba ho Rapid Thermal Cycling Ho pholletsa le Phase Transition Critical Themperatures

PTFE e na le ho feto-fetoha ha molumo ho matla haufi le mocheso oa kamore - haholo-holo ho 19°C le 30°C phase transition points. Haeba lisebelisoa li fapanyetsana khafetsa lipakeng tsa polokelo e batang le mocheso o tikolohong, u se ke oa hatella lesela la PTFE ka thata haholo.

• Ha e kenngoa ka mocheso o tlaase empa e sebelisoa tlas'a mocheso o phahameng, lesela le tla lelefatsa (mohlala, lesela la 1-mithara le otlolla limilimithara tse 'maloa ha le futhumala ho tloha ho 25 ° C ho ea ho 200 ° C).

• Hlomella likopano tsa tsitsipano ka matšeliso a itekanetseng (litsamaiso tsa selemo kapa li-counterweight) ho e-na le ho notlela ka thata.

Molao oa bohlokoa: Le ka mohla u se ke ua tsitsisa lesela la PTFE ka thata mochesong oa kamore ebe u le futhumatsa - katoloso e tla baka maqhubu. Le ka mohla u se ke ua e hatella ka thata ka mocheso o phahameng ebe oa e pholisa - ho honyela ho tla tabola kapa ho hatella thepa.

1. Likopo tsa lebanta la conveyor

Kenya li-tensioner tse thibelang boima ba 'mele kapa tsa selemo bakeng sa ho monya khatholoho ea lesela mochesong o phahameng le ho honyela ha mocheso o tlase. Le ka mohla u se ke ua tiisa lebanta ka tlas'a mocheso o phahameng - sena se tla baka moroalo o mongata nakong ea ho thibela serame. Khatello ea lebanta e lokela ho behoa mocheso o tlaase ka ho fetisisa o lebeletsoeng oa ho sebetsa.

2. Ho lokolla li-liner le maqephe a ho itšehla thajana

Beha fatše ntle le khatello ea maikutlo. Sireletsa hanyenyane ka boima ba 'mele kapa meqathatso e moqotetsane ka lehlakoreng le le leng ho thibela li-crease tse sa feleng tse bakoang ke ho atolosoa ha mocheso.

Ho atolosoa ho sa tsitsang ho etsahala ha lehlakore le leng la lesela le pepesehile mocheso o phahameng ha le leng le ntse le pholile, le etsa hore ho be le ntoa.

Mehato ea ho lokisa:

• Ho kokota ha nakoana ka liforeimi ho e-na le ho hatella ka hohle-hohle

• Khetha lesela le letenya, le phahameng ho feta tekano ea fiberglass ho fokotsa leqephe la ntoa

• Seta esale pele ka lehlakoreng la mocheso o tlase ha ho hlokahala (kenya lesela hore le tle le batalle mocheso o sebetsang)

Tlhahlobo le Tlhokomelo ea Nako le Nako

Kamora ho palama baesekele ea nako e telele ea mocheso, PTFE e tla ba le deformation ea phallo e batang , e bakang bolelele bo sa feleng kapa bofokoli ba lehae.

• Kamehla hlahloba le ho lokisa maemo a tsitsipano - mabanta a ka 'na a hloka ho tsosolosoa hape ka mor'a lipotoloho tse seng kae tsa pele tsa mocheso.

• Lokisa li-bulges le delamination kapele ho qoba khatello ea maikutlo le ho taboha.

• Boitšoaro ba katoloso ea litokomane - haeba lebanta le lula le otlolohile ho feta tekanyo, le ka hloka phetoho kapa substrate e fapaneng e lumellanang le CTE.

Keletso ea Aokai PTFE: Bakeng sa lits'ebetso tse nang le libaesekele tse futhumatsang haholo (mohlala, lipalangoang tsa ontong li palama libaesekele ho tloha tikolohong ho ea ho 250°C makhetlo a mangata ka letsatsi), re khothaletsa lesela le nang le fiberglass e phahameng (CTE e tlase) le ho lekola tsitsipano ea othomathike.
