Lesela la Mocheso o Phahameng oa PTFE: Hobaneng le Mena Hampe le Seo U ka se Etsang

Haeba u kile ua phutha sengoathoana sa PTFE-coated fiberglass lesela ka bohale, mohlomong u ile ua bona white crease line hlaha hang-hang. E mene hape sebakeng se le seng, 'me lesela le ka' na la taboha.

Sena ha se sekoli - ke boitšoaro ba tlhaho ba thepa. PTFE lesela la mocheso o phahameng oa mocheso le ipabola ha le hanyetsa mocheso, lik'hemik'hale, le ho khomarela, empa ho hanyetsa ho feto-fetoha (ho phutha khafetsa ho mamella) ke thepa ea eona e fokolang ka ho fetisisa ea mochine.

Aokai PTFE e lekile bophelo bo feto-fetohang ho pholletsa le botenya le li-weave tse ngata. Sehlooho sena se hlalosa hore na ke hobane'ng ha lesela le phutha hampe, le bapisa le lisebelisoa tse ling, 'me le fana ka litsela tse sebetsang tsa ho sebetsana le moeli.

Hobaneng ha PTFE Fabric e na le Khanyetso e Fosahetseng ea Flex?

Motso oa sesosa ke fiberglass substrate , eseng PTFE coating.

1. Fiberglass - e matla empa e brittle

Lithapo tsa khalase li na le matla a phahameng haholo a ho tsitsipana empa bolelele bo tlase haholo nakong ea khefu (hangata 2-4%). Ha e kobehile khafetsa, likhoele ka bomong li ba le mokhathala le ho robeha. Hang ha likhoele tse 'maloa li robeha, khatello e lebisa tlhokomelo ho tse setseng, e lebisang ho phatlalatsoeng ka potlako - lesela le lla habonolo.

2. PTFE barbotage – e lekanyelitsoeng buffer

PTFE layer e tlotsa likhoele tsa fiber, e fokotsa khohlano e ka hare le ho ntlafatsa hanyenyane. Leha ho le joalo, e ke ke ea felisa ho brittleness ha khalase. E liehisa feela ho phatloha ha fiber ka moeli o monyenyane.

E Bapisoa Joang le Lisebelisoa Tse Ling?

Ntho ea bohlokoa ea ho nka: PTFE-coated fiberglass e lutse qetellong ea bohareng ho isa tlase har'a masela a mocheso o phahameng oa ho hanyetsa. E molemo ho feta khalase e se nang letho empa e mpe haholo ho feta filimi e hloekileng ea PTFE.

Lintlha tse ka Sehloohong tse Amang Flex Resistance

1. Botenya - ntlha ea bohlokoa ka ho fetisisa

Molao oa letsoho: Masela a masesaane a fetoha hantle. Bakeng sa lits'ebetso tse hlokang ho kobeha khafetsa, hlakisa kereiti ea thinnest e fihlelang litlhoko tsa hau tse ling (matla, mocheso).

2. Kaho ea ho loha

• Satin weave - ho phaphamala ha nako e telele ho lumella likhoele hore li thelle hanyenyane, li aba khatello ea maikutlo. Bophelo bo monate ba ho flexible ho feta plain weave.

• Plain weave - lintlheng tse thata tsa interlacing notlela likhoele; khatello ea maikutlo e tobile mateanong a litsela. Khanyetso e mpe le ho feta.

3. Mocheso oa ho sebetsa

Lithempereichara tse phahameng (200-260 ° C), lesela la PTFE lea nolofala, 'me matla a mochini oa fiberglass a fokotseha. Sena se mpefatsa le ho feta flex mokhathala ho hanyetsa. Haeba kopo ea hau e kenyelletsa mocheso o phahameng le ho kobeha khafetsa, lebella bophelo bo khuts'oane.

4. Radius e kobehang

Radius e kholo = bophelo bo bolelele. Ho hlaba ka bohale (radius <1mm) ho etsa mameno a shoeleng ka ho robeha hanghang ha fiber. Bakeng sa lirolara tse tataisang, sebelisa bophara bo boholo bo sebetsang. Joalo ka tataiso e thata, bophara ba rolara e khothaletsoang bonyane ke 10-20x botenya ba lesela.

Lintlha tsa tlhahlobo ea ka hare (Aokai PTFE) : Bakeng sa lesela la 0.13mm satin weave, ho khumama holim'a mandrel ea 10mm e fihletse 500-800 cycles pele ho peperana ho bonahalang. Ho feta mandrel a 5mm, lipotoloho li theohetse ho 100-150. Ho feta 2mm mandrel (sharp crease), ho hloleha ho etsahetse ka har'a lipotoloho tse 20.

Litlhahiso Tse Sebetsang Tsa Kopo

Haeba sesebelisoa sa hau se hloka ho kobeha khafetsa - joalo ka:

• Mabanta a koloi a li-welder a phahameng-frequency

• Mabanta a tsitsipano a pota-potileng li-pulleys tse nyane

• Mabanta a conveyor a ho theola a nang le thinya e bohale

U na le likhetho tse tharo:

1. Khetho ea 1 - Ntlafatsa khetho ea lesela la PTFE ka har'a meeli ea eona

• Khetha limaraka tse tšesaane (0.08mm ho isa ho 0.13mm) ho feta tse boima

• Khetha ho loha ka satin ho e-na le ho loha feela

• Kopa lintlha tsa tlhahlobo ea MIT flex ho tsoa ho morekisi oa hau (ASTM D2176 kapa tse ling tse tšoanang)

• Moralo oa radii e kholoanyane ea ho kobeha ka har'a moralo oa mochini

• Amohela lesela la PTFE e le ntho e ka jeoang - moralo oa ho nchafatsa nako le nako (likhoeli tse ling le tse ling tse 'maloa ho latela palo ea potoloho)

2. Khetho ea 2 - Fetolela filiming e tiileng ea PTFE

Filimi e hloekileng ea PTFE (skived) e na le khanyetso e ikhethang ea flex. Leha ho le joalo, ha e na matlafatso ea khalase ea fiberglass, kahoo e na le matla a tlase a ho tsieleha 'me e lla habonolo tlas'a tsitsipano. E loketse lits'ebetso tsa ho kobeha tse bobebe, tse tlase-tlaase.

3. Khetho ea 3 - Sebelisa aramid kapa lesela le leng la fiber ea tlhaho

Aramid (mohlala, Nomex) kapa lesela la PPS le koahetsoeng ka PTFE le fana ka bophelo bo betere ho feta lesela la PTFE le entsoeng ka khalase. Thekiso ea khoebo: ho fokotsa mocheso o sa khaotseng oa mocheso (ka tloaelo ≤200 ° C) le thepa e fapaneng ea holim'a metsi. Bakeng sa lisebelisoa tse ka tlas'a 200 ° C ka ho kobeha ha boima, nahana ka mekhoa ena e meng.

Aokai PTFE e etsa lesela la aramid le koahetsoeng ke PTFE ka kopo. Ikopanye le rona bakeng sa mocheso le data e feto-fetohang.

Kakaretso - Tseba Meeli, Rala Tumellano

PTFE lesela la mocheso o phahameng le ema hantle khahlanong le tsitsipano, mocheso o phahameng (260 ° C), le tlhaselo ea lik'hemik'hale. Empa khanyetso ea eona e fokolang ke tšitiso ea 'nete. Ha e khone ho mamella ho phutha khafetsa joalo ka mabanta a rabara kapa filimi e hloekileng ea PTFE.

E sebedise moo ho kobehang ho leng bonolo kapa ho sa tloaelehang.
Moo ho kobehang ka bohale kapa khafetsa ho ke keng ha qojoa, e-ba mosesaane, sebelisa satin weave, eketsa radius e kobehang, kapa switjha thepa.

Aokai PTFE e fana ka lintlha tsa tlhahlobo tse feto-fetohang bakeng sa limaraka tsohle tsa rona tsa masela. Re ka u thusa ho khetha botenya bo nepahetseng le ho loha bakeng sa litlhoko tsa ho kobeha tsa kopo ea hau.
