PTFE High-Temperature Cloth – Single-Dip vs. Multi-Dip Impregnation Process

PTFE high-themperature cloth (PTFE-coated fiberglass) e ka etsoa ho sebelisoa mekhoa e 'meli e fapaneng haholo: ho kenngoa ha single-dip le multi-dip impregnation . Khetho pakeng tsa bona e khetholla botenya ba ho roala, boleng ba bokaholimo, boemo ba ts'ebetso le litšenyehelo.

Ka ts'ebetso ea ho qoelisoa ha 'ngoe, lesela la fiberglass le feta ka potoloho e le 'ngoe feela e felletseng ea ho omisa-ho omisa. Ts'ebetsong ea li-multi-dip, e feta ka makhetlo a mangata - hangata 2-3 e matha ho feta leshome le metso e 'meli - e haha ​​​​PTFE lera ka lera.

Aokai PTFE e sebelisa lits'ebetso ka bobeli ho latela ts'ebeliso. Tataiso ena e hlalosa tlhaloso, phallo ea ts'ebetso, litšoaneleho, le lits'ebetso tse tloaelehileng tsa e 'ngoe le e' ngoe, hammoho le papiso ea ts'ebetso ea lehlakoreng le leng.

Ts'ebetso ea Single-Dip Impregnation - E potlakile ebile e na le litšenyehelo

1. Tlhaloso le mokhoa oa ho phalla

Tlhaloso: Lesela la Fiberglass le feta ka potoloho e le 'ngoe feela e feletseng ea ho omisa-ho omisa ho hlahisa lesela le phethiloeng la PTFE.

Phallo ea ts'ebetso:
Lesela la fiberglass → ho kenngoe ka PTFE dispersion → pente ea ho pepeta/mohatla oa ngaka ho laola ho nkela resin → ho omisa mocheso o tlase bakeng sa ho ntšoa ha metsi → sintering ea mocheso o phahameng (360-400°C) ho qhibilihisa PTFE filiming e tsoelang pele → ho pholile le ho tima.

2. Litšobotsi tsa ts'ebetso

• Resin pickup e na le moeli, e fana ka le lesesaane, le nang le sebōpeho se tlaase lesela

• Moetso o lohiloeng oa fiberglass e ke ke ea tlatsoa ka botlalo, e bakang sebaka se makukuno se nang le li-micro-pinholes

• Tšireletso e sa fellang ea PTFE e lebisa ho matla a fokolang a fokolang, matla a dielectric, k'hemik'hale ea ho kenella ka lik'hemik'hale, le ts'ebetso e sa tsitsang.

• Potoloho ea tlhahiso e khuts'oane ka ts'ebetso e phahameng le theko e tlase ea tlhahiso melemo ea

3. Likopo tse tloaelehileng

Lesela la ho qoelisa le le leng le amoheloa bakeng sa maemo a nang le litlhoko tse tlase ho botenya, ho se mele, le boreleli ba bokaholimo:

• Li-gaskets tsa boemo bo tlase tsa insulating

• Limmete tsa nakoana tse sa thupeng

• Lisebelisoa tse ke keng tsa fetisoa tse bolokang moea o sa fellang

• Litšebeliso tse seng tsa bohlokoa tsa indasteri moo litšenyehelo e leng mokhanni oa mantlha

Multi-Dip Impregnation Process – Layer-by-Layer Performance Build-Up

1. Tlhaloso le mokhoa oa ho phalla

Tlhaloso: Fiberglass substrate e feta ka makhetlo a mangata a impregnation-drying-sintering, hangata ho tloha ho 2-3 ho ea ho tse fetang leshome le metso e 'meli. Karolo e 'ngoe le e' ngoe e latelang e behiloe holim'a seaparo sa PTFE se ntseng se le teng ho haha ​​​​botenya, ho tlatsa likheo, le ho lokisa mefokolo.

Phallo ea ts'ebetso:
Lesela la fiberglass → ho emola ha 1 → ho omisa → ho omisa → ho pholile → ho pholile → ho emola ka lekhetlo la bobeli → ho omisa → ho pholile → ho pholisa → ho kenngoe ka lekhetlo la boraro ... Ho felloa ke matla ha sepheo, sebōpeho-puo le litlhaloso tsa tshebetso li fihletsoe.

Phapang ea leano:

• Lipotoloho tsa pele: Viscosity e tlase, phallo e phahameng ea PTFE - e kenella ka botlalo ka har'a likhoele tsa fiber.

• Mehato ea morao-rao: li-viscosity tse phahameng kapa li-dispersions tse tiileng - li haha ​​​​lifilimi tse holimo ebe li koala masoba.

2. Litšobotsi tsa ts'ebetso

• Botenya le PTFE loading e ka laoloa ka nepo

• Karolo ea PTFE e ka fihla ho 50-70% kapa ho feta

• Ho kenella khafetsa le ho koala likheo lipakeng tsa likhoele tsa fiber le ho tlosa masoba, ho fana ka lesela le boreleli, le kopaneng.

3. Ts'ebetso e phahameng

• Lintho tse babatsehang tse sa thupeng le ho lokolla

• E ikhethang ka ho fetisisa lik'hemik'hale-corrosion resistance and impermeability

• E ntlafalitse haholo matla a dielectric le resistivity ea molumo

• Sebopeho se tsitsitseng se nang le mocheso oa nako e telele oa tšebeletso ho fihlela ho 260 ° C

Khoebo: Nako e atolositsoeng ea tlhahiso ea nako, tšebeliso e matla ea matla, taolo e thata ea ts'ebetso, le litšenyehelo tse phahameng tsa tlhahiso ka kakaretso.

4. Likopo tse tloaelehileng

Multi-dip cloth e sebeletsa maemo a holimo, a maemo a holimo a indasteri moo ts'ebetso e lokafatsang litšenyehelo:

Papiso ea Ts'ebetso ea Bohlokoa - Ka Mathoko

Kakaretso - Ho Khetha Mokhoa o Nepahetseng oa Kopo ea Hao

Ho qoelisoa ha 'ngoe ke mokhoa o potlakileng oa ho roala filimi e tšesaane o nang le linako tse khutšoane tsa tlhahiso le litšenyehelo tse tlase, leha ho le joalo o fokotsoa ke pheletso e mpe le ts'ireletso e tlase.

Multi-dip impregnation ke mokhoa oa ho kenella ka mekhahlelo le mokhoa oa ho haha ​​o koahelang ka botlalo karoloana ea fiberglass. E hlahisa lesela le boreleli, le teteaneng le koahetsoeng ke PTFE le ts'ebetso ea boemo bo holimo ka litšenyehelo tsa ho phalla ha mosebetsi le litšenyehelo tse phahameng.

Aokai PTFE e etsa masela a PTFE a dip a le mong le a mangata. Bakeng sa lits'ebetso tse hlokang indasteri, hoo e batlang e le masela ohle a phahameng a ts'ebetso a PTFE-impregnated fiberglass a hlahisoa ka mokhoa oa li-multi-dip. Ikopanye le rona ho buisana ka hore na ke sehlopha sefe se lumellanang le litlhoko tsa hau tsa kopo.

Litaba tsa tekheniki tse boletsoeng ka holimo li fanoa ke Jiangsu Aokai New Materials Technology Co., Ltd.

Haeba u ka rata ho fumana lintlha tse qaqileng tsa tekheniki, linyeoe tsa kopo le litharollo tse ikhethileng bakeng sa lethathamo la lihlahisoa tsa rona tse felletseng, ho kenyeletsoa lesela la mocheso o phahameng oa PTFE, tepi e khomarelang mocheso o phahameng oa PTFE, lebanta le nang le mocheso o phahameng oa mocheso oa PTFE, lebanta le se nang mocheso, lesela le nang le lehlakore le le leng la PTFE, lesela le hananang le mocheso le fiberglass ka lintlha tsa ho ikopanya le tse ka tlase:
