Dab tsi yog cov kab nrawm nrawm rau cov kab ntau lawm impregnation ntawm PTFE high-temperature npuag?

I. Hom Kab Ceev Tswj Ntau Yam

Txoj kab ceev ntawm lub PTFE high-temperature npuag impregnation ntau lawm kab yog feem ntau tswj nyob rau hauv thaj tsam ntawm 2 mus rau 15 m / min, nrog rau kev ruaj ntseg kev khiav hauj lwm ntau yog 3 mus rau 8 m / min. Cov ntaub nyias nyias lossis qee cov kab ceev ceev tuaj yeem ncav cuag 10 mus rau 15 m / min. Ua piv txwv qhov yuav tsum tau sintering ntawm 1.5 mus rau 3 feeb thiab qhov cub zoo ntev ntawm 20 meters, txoj kab theoretical ceev yuav yog kwv yees li 6.7 txog 13.3 m / min. Hauv kev xyaum, qhov kev nyab xeeb yuav tsum tau tshwj tseg, nrog rau qhov tseeb ceev feem ntau teem ntawm 60% mus rau 80% ntawm lub siab txwv, yog li feem ntau ua haujlwm nyob rau hauv thaj tsam ntawm 4 mus rau 10 m / min.

II. Kev txwv los ntawm Impregnation Penetration thiab txheej txheej txheej

1. Lub sijhawm impregnation thiab nkag mus

Raws li tau sau tseg los ntawm Jiangsu PTFE high-temperature npuag chaw tsim tshuaj paus: fiberglass ntaub yuav tsum tau tag nrho saturated nrog PTFE emulsion thiab nkag mus rau hauv lub sab hauv ntawm lub fiber bundles. Yog tias cov kab nrawm dhau lawm, qhov tsis txaus impregnation tshwm sim, yooj yim ua rau cov resin tshaib plab, qhuav fibers, thiab cuam tshuam adhesion thiab tso tawm zog. The emulsion viscosity, solids concentration, and the fabric's weave density (thick fabrics, tight weaves) all reduce the penetration rate, meaning that thick and dense fabrics must be run at slower speeds.

2. Txheej Thickness thiab naj npawb ntawm daim ntawv thov dhau

High-temperature fabric feem ntau yuav tsum muaj ntau yam impregnation thiab sintering dhau (tsawg kawg 2 mus rau 3 kis, qee zaum mus txog 6 lossis ntau dua). Txhua txheej txheej yuav tsum nyias nyias kom ua tiav cov txheej txheem tsis muaj qhov tsis zoo. Thawj kis yog npaj kom thauj tog rau nkoj lub hauv paus ntaub, yog li qhov ceev yog feem ntau qeeb; Cov ntawv hla tom ntej tuaj yeem nce nruab nrab, tab sis txhua qhov dhau los yuav tsum ua kom muaj qib txaus thiab ua tiav sintering.

III. Cov kev txwv los ntawm kev ziab, sintering, thiab cov cuab yeej muaj peev xwm

1. Thaum tshav kub kub kho qhov chaw nyob thiab qhov cub ntev

Cov ntaub ntub dej yuav tsum tau ziab, sintering (ntawm 380-400 ° C kom fuse PTFE hais rau hauv zaj duab xis), thiab tom qab ntawd txias. Lub sintering theem feem ntau yuav tsum tau kaum vib nas this mus rau ob peb feeb. Kab ceev sib npaug ntawm qhov cub qhov ntev muab faib los ntawm lub sijhawm kho cua sov uas xav tau. Thaum lub qhov cub ntev yog tsau, yog sintering yuav tsum tau 2 feeb, qhov ceev yog txwv rau kwv yees li 5 mus rau 10 m / min. Kev ceev ntau dhau ua rau tsis tiav sintering ntawm txheej, ntxuav hniav dawb, tsis zoo adhesion, thiab tsim cov pinholes thiab npuas.

2. Qhov kub thiab txias tsis sib xws thiab cua kub ncig

Kev siv cua kub zoo thiab qhov kub ntawm qhov cub tsis sib xws tuaj yeem ua rau lub sijhawm kho cua sov kom luv, ua rau txoj kab nrawm dua. Piv txwv li, qhov tsis sib xws ntawm qhov kub thiab txias tsis txaus los yog tsis txaus airflow yuav tsum tau qeeb qeeb kom ntseeg tau tias cov txheej txheem sib xws ntawm cov ntaub dav.

IV. Kev txwv los ntawm substrate, emulsion, thiab cov kev xav tau zoo kawg

1. Substrate Thickness, Nyhav, thiab dav

Ultra-nyias fabrics (piv txwv li, 0.08 mm) yuav khiav ntawm speeds siab tshaj 10 m / min, thaum thicker fabrics ntawm 0.3 mus rau 0.5 mm los yog siab dua, raws li zoo raws li high-strength, high-density fabrics, yuav tsum tau qeeb speeds (2 mus rau 5 m / min) vim qeeb cua sov hloov. Cov ntaub dav dav yog ua rau kev sib hloov tsis sib xws thaum lub sij hawm impregnation thiab ziab, feem ntau yuav tsum tau ceev txo kom ntseeg tau tias tag nrho cov uniformity.

2. Emulsion Formulation thiab Rheology

Impregnation kua nrog cov ntsiab lus siab thiab cov viscosity siab muaj qhov nkag mus qeeb qeeb, xav tau cov kab qis dua. Hom thiab ntau npaum li cas ntawm cov tshuaj ntub dej thiab cov thickeners nyob rau hauv formulation cuam tshuam rau wetting ceev thiab lub cev qhuav dej tus nqi, ncaj qha cuam tshuam rau lub siab tshaj plaws cia kab ceev.

3. Cov khoom lag luam qib yuav tsum muaj

Rau cov ntawv thov kev xav tau zoo, xws li cov khoom noj ci thiab cov khoom siv hluav taws xob siv hluav taws xob, cov kev xav tau ntawm cov pinhole suav, nto smoothness, thiab thickness kam rau ua yog nruj heev. Nyob rau hauv xws li mob, ceev yuav tsum tau fij ntau zaus rau qhov zoo, ua kom cov kab ceev ntawm ib theem qis kom ntseeg tau tias qhov ntom ntom, xoom-xws li txheej.
