Yuav ua li cas kom lav qhov Flatness ntawm PTFE High-Temperature Cloth Thaum Sintering

Sintering yog cov kauj ruam tseem ceeb uas PTFE cov khoom yaj, ntws, thiab fuse rau hauv cov yeeb yaj kiab tas mus li. Tab sis nws kuj yog theem uas flatness yog feem ntau yooj yim ploj. Qhov tsis sib xws, qhov kub thiab txias hloov pauv, lossis kev tswj tsis txaus tuaj yeem ua rau tsis tuaj yeem thim rov qab wrinkles, wavy npoo, thiab warpage uas tsis tuaj yeem kho tom qab.

Lub hauv paus ntsiab lus tseem ceeb rau kev tswj kom tiaj tus yog kev tswj xyuas nruj ntawm qhov nro, qhov kub thiab txias - ua kom muaj kev sib koom ua ke ntawm cov fiberglass substrate thiab molten PTFE txheej.

Aokai PTFE  (PTFE fiberglass daim ntaub ) tau tsim cov txheej txheem sintering muaj zog los xyuas kom meej qhov sib xws. Phau ntawv qhia no suav txog tsib lub ntsiab lus tseem ceeb rau kev ruaj khov hauv kev tsim khoom loj.

Cov cuab yeej txwv - Senter Tshuab yog qhov yuav tsum tau ua

Qhov no yog cov txheej txheem tseem ceeb los tiv thaiv weft shrinkage thiab wavy selvedges. Ib tus pin stenter (los yog clip stenter) yuav tsum tau muab tso rau hauv lub qhov cub sintering.

1. Crosswise shaping

Pin daim hlau tho ntaub npoo. Los ntawm kev kho cov kab dav dav ntawm cov saw hlau, me me transverse nro yog siv - lossis tsawg kawg, cov ntaub ntawv dav dav yog tswj kom tiv thaiv thermal shrinkage kev ntxhov siab ntawm lub substrate nyob rau hauv high tshav kub. Yog tsis muaj kev txwv no, cov ntaub dav shrinks thiab cov npoo ua wavy.

2. Longitudinal tswj

Precise ceev sib txawv ntawm pem hauv ntej thiab nram qab rollers ntxiv kaw-voj nro tswj xa ultra-low thiab khov kho longitudinal nro:

• Kev sib zog ntau dhau - tawg cov txheej los yog ua rau tom qab txias shrinkage thiab warpage

• Tsis txaus nro - ua rau lengthwise wrinkles (cov ntaub 'bunches up')

Kev Tshawb Fawb Kub Kub Profile - Gradient cua sov thiab qeeb txias

Lub gradient nkhaus ntawm maj mam cua sov, tag nrho melting, thiab qeeb txias yog yuav tsum tau tshem tawm thermal shock thiab kev ntxhov siab vim warpage.

1. Thaj chaw cua sov

Kub nce maj mam nyob ib ncig ntawm PTFE melting point (327 ° C) kom sib npaug sab hauv thiab saum npoo ntaub kub. Lub zos overheating los yog kub ceev surge ua rau uneven shrinkage thiab mus tas li creases. Lub hom phiaj yog tso cai rau cua sov kom nkag mus rau hauv cov ntaub ntawv tuab ua ntej tag nrho melting pib.

2. Sintering tuav cheeb tsam

Kev ntsuas kub tsis tu ncua ntawm 380-400 ° C rau lub sijhawm nyob txaus. Qhov no:

• Tag nrho melts PTFE hais mus rau hauv ib tug tas mus li zaj duab xis

• Tso cov residual sab hauv kev nyuaj siab ntawm fiberglass nyob rau hauv restrained tiaj tus mob

• Ua kom tiav fusion thiab densification

3. Qhov chaw txias - feem ntau saib tsis taus, tseem ceeb heev

Qhov no yog theem uas warpage feem ntau tshwm sim. Yuav tsum tau ua kom txias qeeb thaum tuav stenter tuav kom txog thaum kub poob qis hauv qab PTFE crystallization point (kwv yees li 310 ° C ).

Txoj cai tseem ceeb: Kev quab yuam cua txias sai ua rau tsis sib haum xeeb ntawm cov txheej txheem thiab cov substrate - ua rau muaj kev tsis sib haum xeeb lossis curling selvedges uas tsis tuaj yeem flattened tom qab. Khaws cov ntaub so kom txog thaum PTFE tau tag nrho crystallized thiab kaw rau hauv nws cov duab kawg.

Substrate Pretreatment thiab Txheej Uniformity

Flatness thaum lub sij hawm sintering nyob ntawm seb yuav ua li cas ua ntej cov ntaub nkag mus rau hauv lub cub tawg.

1. Pre-shrinking ntawm puag ntaub

Ua ntej PTFE impregnation, fiberglass daim ntaub undergoes high-temperature dewaxing thiab pre-shrinking kom tshem tawm weaving residual kev nyuaj siab. Qhov no ua rau txo qis qis qis thaum lub sij hawm sintering thiab nteg lub hauv paus rau superior flatness.

Aokai PTFE ceeb toom: Tsis muaj qhov ua ntej shrinking, lub fiberglass yuav sim ua ntawv cog lus thaum lub sij hawm sintering - sib ntaus sib tua tiv thaiv stenter restraint thiab ua rau uneven kev ntxhov siab faib.

2. Uniform txheej thickness

PTFE impregnated txheej yuav tsum muaj cov tuab tuab tuab thoob plaws tag nrho cov ntaub. Cov txheej tsis sib xws ua rau lub sijhawm sib txawv ntawm qhov sib txawv - cov cheeb tsam nyias yaj sai dua li cov cheeb tsam tuab - ua rau muaj kev ntxhov siab zoo ib yam li txiv kab ntxwv tev kev ntxhib los mos thiab ruining flatness.

• Kev tswj kom raug ntawm impregnation, kws kho hniav txheej txheej, thiab nyem dov txheej txheem yog qhov tseem ceeb.

• Txawm tias me me thickness variations (0.01mm) tuaj yeem ua rau pom qhov tsis xws luag.

Airflow Arrangement thiab Precision Guide Rollers

1. Cov cua kub tsim tsim

Txais tos rau sab saum toj-thiab-hauv qab txee-tshuab los yog cov cua kub sib txawv hauv lub qhov cub kom tsis txhob muaj ib sab muaj zog airflow ncaj qha mus tsoo cov ntaub - uas ua rau cov cim flutter. Kev ruaj ntseg cua cushion kev txhawb nqa nyob rau hauv kab rov tav qhov cub tiv thaiv cov ntaub sagging dhau ntev ncua kev ncua.

2. nruj parallelism ntawm rollers

Tag nrho cov kev taw qhia chais thiab nro rollers yuav tsum muaj kev sib luag ntawm ultra-high parallelism thiab huv si yam tsis muaj cov nplaum nplaum:

• Cov ntaub me me sib txawv ua rau tsis sib npaug ntawm ob sab thiab unilateral wrinkles

• Yuav tsum tau nruab ib qho kev kho ntug kho qhov system

• Kev tu tsis tu ncua tiv thaiv cov nplaum nplaum uas ua rau muaj kev hloov pauv hauv cheeb tsam

Summary - Cov Ntawv Qhia Flatness

Zoo meej flatness tsis tiav los ntawm sab nraud nias quab yuam. Hloov chaw, nyob rau hauv cov txheej txheem kev tswj hwm ntawm lub tshuab stenter, qhov kub thiab txias thiab nro yaj thiab integrate PTFE txheej nrog fiberglass substrate rau hauv ib qho kev sib xyaw ua ke, nrog rau tag nrho cov kev ntxhov siab seem tso tawm los ntawm kev ua kom txias.

Deviation nyob rau hauv ib qho kev sib txuas ib leeg yuav nws thiaj li manifest as uneven fabric nto.

Aokai PTFE tswj tag nrho cov kev txwv no kom xa PTFE daim ntaub nrog lav zoo. Rau cov ntawv thov uas xav tau cov ntaub npuag ultra-nplua (xws li, PCB laminating, hnub ci laminators), peb muab cov ntsiab lus nruj dua thiab cov txheej txheem flattening ntxiv.
