PTFE High-Temperature Cloth – Ib-Dip vs. Multi-Dip Impregnation txheej txheem

PTFE high-temperature fabric (PTFE-coated fiberglass) tuaj yeem tsim siv ob txoj hauv kev sib txawv: ib leeg-dip impregnation thiab ntau-dip impregnation . Qhov kev xaiv ntawm lawv txiav txim siab txheej thickness, nto zoo, qib kev ua tau zoo, thiab tus nqi.

Hauv cov txheej txheem ib zaug, cov ntaub fiberglass dhau los ntawm ib qho ua tiav impregnation-drying-sintering voj voog. Nyob rau hauv ib tug ntau-dip txheej txheem, nws dhau mus rov qab mus - feem ntau 2-3 khiav mus rau ntau tshaj ib lub kaum os - tsim PTFE txheej los ntawm txheej.

Aokai PTFE siv ob txheej txheem nyob ntawm daim ntawv thov. Phau ntawv qhia no piav qhia txog lub ntsiab lus, cov txheej txheem khiav, cov yam ntxwv, thiab cov kev siv ib txwm ntawm txhua tus, nrog rau kev sib piv ntawm kev ua haujlwm ib sab.

Ib leeg-Dip Impregnation txheej txheem - ceev thiab raug nqi

1. Txhais thiab txheej txheem ntws

Txhais: Fiberglass npuag mus dhau ib lub voj voog ntawm impregnation-drying-sintering los tsim cov ntaub PTFE-coated tiav.

Cov txheej txheem ntws:
Fiberglass npuag → impregnation nrog PTFE dispersion → nyem-tawm / tus kws kho mob-hla txheej los tswj cov khoom khaws cia → qis kub kom qhuav rau dej tshem tawm → kub kub sintering (360-400 ° C) kom yaj PTFE rau hauv cov yeeb yaj kiab tas li → txias thiab winding-up.

2. Cov yam ntxwv txheej txheem

• Resin pickup yog txwv, yielding nyias-gauge, low-grammage ntaub

• Qhov kev ntxhib los mos ntawm fiberglass tsis tuaj yeem ua kom tiav, ua rau lub ntsej muag ntxhib nrog micro-pinholes

• Tsis tiav PTFE kev pab them nqi ua rau lub zog tensile kuj tsis tshua muaj zog, lub zog dielectric, tshuaj lom neeg nkag mus, thiab kev ua haujlwm tsis zoo

• Lub voj voog ntau lawm yog luv nrog kev ua haujlwm siab thiab tsis tshua muaj nqi tsim khoom zoo

3. Cov ntawv thov ib txwm

Ib daim ntaub-dip yog saws rau cov xwm txheej uas tsis tshua muaj kev xav tau ntawm thickness, impermeability, thiab nto smoothness:

• Tsawg-qib insulating gaskets

• Ib ntus tsis-stick lev

• Semi-permeable cov ntaub ntawv uas khaws ib feem ntawm huab cua permeability

• Tsis tseem ceeb kev lag luam siv qhov twg tus nqi yog thawj tus neeg tsav tsheb

Multi-Dip Impregnation Txheej Txheem - Txheej-los-Txheej Kev Ua Haujlwm Tsim-Up

1. Txhais thiab txheej txheem ntws

Lus Txhais: Lub fiberglass substrate tau rov qab mus rau impregnation-drying-sintering, ib txwm muaj li ntawm 2-3 khiav mus txog rau ntau tshaj ib lub voj voog. Txhua txheej tom ntej yog muab tso rau ntawm PTFE txheej uas twb muaj lawm los tsim cov tuab, sau cov voids, thiab kho qhov tsis xws luag.

Cov txheej txheem ntws:
Fiberglass npuag → 1st impregnation → ziab → sintering → txias → 2nd impregnation → ziab → sintering → txias → 3rd impregnation ... Thaum kawg winding-up ib zaug lub hom phiaj thickness, grammage, thiab kev ua tau zoo specifications tiav.

Strategy variation:

• Lub voj voog pib: Tsawg-viscosity, siab nkag mus rau PTFE dispersion - tag nrho infiltrates hauv fiber ntau

• Cov theem tom ntej: Siab dua-viscosity los yog siab dua-khoom-cov ntsiab lus dispersions - tsim cov zaj duab xis saum npoo thiab ntsaws pinholes

2. Cov yam ntxwv txheej txheem

• Thickness thiab PTFE loading tuaj yeem raug tswj hwm

• PTFE feem ntau tuaj yeem ncav cuag 50-70% lossis siab dua

• Recurring impregnation thiab sintering sau qhov khoob ntawm fiber ntau filaments thiab tshem tawm cov pinholes, xa ib tug du, compact txheej.

3. Kev ua tau zoo tshaj plaws

• Zoo heev tsis-stick thiab tso tawm zog

• Zoo heev tshuaj-corrosion kuj thiab impermeability

• Drastically txhim kho dielectric zog thiab ntim resistivity

• Kev ruaj khov kev ntseeg siab nrog kev pabcuam ntev mus txog 260 ° C

Kev lag luam tawm: Kev tsim cov khoom siv sij hawm ntev, kev siv hluav taws xob siab, kev tswj cov txheej txheem nruj, thiab cov nqi tsim khoom ntau dua.

4. Cov ntawv thov ib txwm

Multi-dip daim ntaub pab premium-qib, high-end industrial sectors qhov kev ua tau zoo qhia tus nqi:

Kev sib piv qhov tseem ceeb - Ib sab ntawm sab

Summary - Xaiv cov txheej txheem zoo rau koj daim ntawv thov

Ib leeg-dip impregnation yog txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej luv luv thiab cov nqi qis, tab sis txwv los ntawm qhov ntxhib nto tiav thiab kev tiv thaiv tsis zoo.

Multi-dip impregnation yog txheej txheej-los-txheej infiltration thiab tsim-up txheej txheem uas tag nrho encapsulates fiberglass substrate. Nws ua kom du, ntom PTFE-coated ntaub nrog hwm qib kev ua tau zoo ntawm tus nqi ntawm kev ua haujlwm nyuaj thiab cov nqi siab dua.

Aokai PTFE manufactures ib leeg-dip thiab multi-dip PTFE daim ntaub. Rau kev thov kev lag luam, yuav luag txhua qhov kev ua haujlwm siab PTFE-impregnated fiberglass fabrics yog tsim los ntawm ntau txoj kev dip. Hu rau peb los tham txog qib twg uas haum rau koj daim ntawv thov.
