Ua tiav cov txheej txheem tsim khoom ntawm PTFE Emulsion Impregnated Fiberglass Ntaub

Jiangsu Aokai Cov Khoom Tshiab, PTFE cov chaw tsim khoom kub kub, coj koj mus rau tag nrho cov txheej txheem.

PTFE high-temperature npuag, tshuaj hu ua polytetrafluoroethylene (PTFE) coated fiberglass daim ntaub , yog ib qho zoo heev polymer composite khoom. Nws cov khoom siv tsis yog txheej txheem txheej txheej yooj yim, tab sis cov txheej txheem thermal thiab tshuaj lom neeg. Txhawm rau tsim cov khoom zoo PTFE kub-kub npuag, yuav tsum tau ua cov txheej txheem plaub-theem nruj: lub hauv paus ntaub npaj, impregnation tov tshuaj, core impregnation thiab sintering, thiab tom qab kho..

Theem 1: Pretreatment ntawm Base Fabric

Cov theem no txiav txim siab lub zog txhua yam thiab kev ncaj ncees ntawm cov ntaub PTFE zaum kawg.

Thermal Cleaning (Dewaxing) Cov fiberglass yarn siv rau weaving PTFE npuag muaj cov organic sizing agents thaum tsim khoom. Yog tias tsis tau muab tshem tawm, cov neeg ua haujlwm no cuam tshuam qhov adhesion ntawm PTFE txheej tom ntej. Yog li ntawd, thawj kauj ruam yog pub cov ntaub hauv paus rau hauv lub qhov cub kub (kwv yees li 350 ° C) kom ceev dewaxing kom huv si ntawm fiberglass substrate.

Kev hloov kho deg Los txhim kho kev sib raug zoo ntawm fiberglass thiab PTFE txheej resin, lub hauv paus ntaub yog kho nrog tus neeg sawv cev silane coupling. Cov kauj ruam no ua kom muaj zog interlaminar tev lub zog thiab tiv thaiv kev delamination lossis txheej txheej hauv cov khoom tiav.

Theem 2: Kev Npaj ntawm PTFE Impregnation Emulsion

Lub cev thiab tshuaj lom neeg cov khoom ntawm cov ntaub zaum kawg yog txiav txim siab loj nyob rau theem no.

· Emulsion Mixing Cov tub ntxhais raw khoom yog concentrated PTFE dispersion . Raws li cov ntawv thov sib txawv - xws li kev ua haujlwm siab tsis zoo rau cov khoom noj ci los yog kev hnav siab rau kev tso tawm cov ntaub - cov khoom ntim thiab cov khoom ntxiv raug ntxiv rau hauv emulsion. Cov tshuaj formulated impregnation yog qhov tseem ceeb rau kev txheeb xyuas qib ntawm cov ntaub PTFE tiav.

Theem 3: Core Impregnation thiab Sintering

Qhov no yog cov txheej txheem tseem ceeb uas muab PTFE npuag nws qhov kev ua tau zoo tshwj xeeb, feem ntau cuam tshuam nrog kev rov ua dua.

Ntau Impregnations Raws li kev tswj nruj tas li, lub hauv paus ntaub pretreated hla rov qab los ntawm lub tank ntim nrog PTFE emulsion. Txhawm rau ua tiav qhov xav tau tuab thiab ntom, cov kab ntau lawm tau txais cov txheej txheem cyclic: impregnation → ziab → sintering . Txhua lub voj voog yog ua kom cov txheej txheej hnyav.

Qhuav Cov ntaub impregnated semi-tiav lawm dhau los ntawm lub qhov cub kub (kwv yees li 100 ° C) kom maj mam tshem tawm cov dej noo. Kev tswj tsis raug ntawm theem no yooj yim ua rau npuas lossis pinholes thaum sintering, ua rau kev ua haujlwm tsis zoo ntawm rwb thaiv tsev.

High-Temperature Sintering Qhov no yog lub plawv ntawm cov txheej txheem tsim khoom. Cov txheej ntub dej yog sintered ntawm kwv yees li 380 ° C, tso cai rau PTFE hais kom tag nrho yaj thiab ntws, tsim cov yeeb yaj kiab tiv thaiv. Lub peev xwm ntawm PTFE npuag tuaj yeem ua haujlwm ntev ntawm 260 ° C los ntawm polymer saw recrystallization hauv cov kauj ruam no. Incompletely sintered npuag yog qhov ua rau tawg thiab poob ntawm cov khoom tsis-stick.

Kauj Ruam 4: Tom qab Kev Kho Mob thiab Kev Tshuaj Xyuas Cov Khoom Ua tiav

Tom qab sintering, cov ntaub yuav dhau mus ntxiv cov txheej txheem tiav.

Kub-Press Chaw thiab Kev Kho Ntoj Siab High-end PTFE fabrics (xws li cov siv rau conveyor siv) yog calendered los ntawm kub rollers kom tiaj tus nto thiab txo cov kev ntxhov siab sab hauv. Rau PTFE fabrics siv nyob rau hauv high-frequency tooj liab-clad laminates, tshwj xeeb corona kho yog siv los ua kom nto roughness.

Lamination txheej txheem Rau high-end pom daim ntaub ntawv, ib tug nyias txheej ntawm nthuav polytetrafluoroethylene (ePTFE) microporous membrane yog laminated rau saum npoo, tsim ib tug composite lim nruab nrab nrog ntau dua pom efficiency.

Aokai Cov Khoom Siv Tshiab siv kev tshuaj xyuas nruj. Cov khoom kawg raug sim siv lub grammage tester, high-voltage tester, thiab tensile tester. Tsuas yog cov khoom lag luam nrog cov tuab tuab, tsis muaj pinholes, thiab ua raws li qhov yuav tsum tau ua raws li qhov yuav tsum tau muaj hluav taws xob raug tso tawm raws li cov khoom tsim nyog.

Cov ntaub ntawv saum toj no yog muab los ntawm Jiangsu Aokai New Materials Technology Co., Ltd.
