Yuav Ua Li Cas Qhia Txog Cov Cuab Yeej Siv Hluav Taws Xob nrog Cov Txheej Txheem Hloov Nto Rau Kev Ua Ntau Yam Khoom?

Ib hnub kev tshawb fawb thiab kev tsim kho xovxwm lossis lub khw muag khoom yuav tuaj yeem pwm cov khoom siv roj hmab thiab hnub tom qab kho cov nplaum nplaum epoxy. Ib qho, ruaj platen nto tsis tuaj yeem muab ob qho tib si zoo uas tsis yog - tus cwj pwm uas xav tau rau elastomers thiab kev tswj kev sib txhuam lossis hnav tsis kam xav tau rau cov khoom siv ntxiv. Lub kaw lus modular nrog qhov hloov pauv tau yooj yim ntawm qhov chaw cuam tshuam ua rau kev siv cov cua sov ib leeg rau ntau yam txheej txheem yam tsis muaj kev hloov pauv mus tas li.

Lub tswv yim tsim no entails ib tug hloov nto liner cua sov platen ntau yam ntaub ntawv txoj kev uas converts ib tug nruj thermal ntsuas rau hauv ib tug adaptable, reconfigurable ua platform.

Replaceable Surface Liner System Concept
Lub ntsiab tivthaiv ntawm lub system yog cov pa, tawv cua sov platen ua los ntawm steel los yog txhuas. Lub hauv paus qauv no muaj:

Embedded cartridge heaters los yog cov khoom cua kub tsis kam

Distributed kub sensing (RTDs los yog thermocouples)

Cov qauv kev txhawb zog rau kev sib faib ntawm lub siab

Precision-ua kom tiaj tiaj rau thermal uniformity

Tsis txhob tso lub hauv paus saum npoo ncaj qha rau hauv kev sib cuag nrog cov txheej txheem cov ntaub ntawv, nyias nyias, hloov tau liner yog mechanically ruaj ntseg rau lub ntsej muag platen. Lub liner yog lub cev interface uas hu rau cov txheej txheem.

Lub platen muaj lub hnab looj tes hloov ceev, zoo heev rau txhua yam nws xav tau kov.

Hom Kev Hloov Nto Liners
PTFE & PFA Liners rau Tsis yog -Daim ntawv thov lo
Fluoropolymer liners feem ntau yog siv rau cov ntawv nplaum nplaum, resins lossis kho cov khoom sib xyaw.

Common nta yog:

Thickness yog 0.5-1.0 hli

Cov yam ntxwv tso tawm zoo heev

Cov tshuaj tiv thaiv zoo heev.

Tsawg zog nto

Yooj yim pauv tom qab siv

Cov ntaub ntawv no pab tiv thaiv cov khoom los ntawm kev nplaum thaum tshav kub- nce mus txog, txo lub sij hawm ntxuav thiab tshem tawm qhov xav tau rau cov txheej txheem tso tawm mus tas li.

Hlau Liners rau hnav daim ntaub ntawv
Cov txheej txheem uas siv cov khoom siv abrasive lossis cov ntaub ntawv sau, qhov sib txawv, yuav tsum muaj cov hlau ruaj khov.

Qee qhov kev xaiv niaj hnub yog:

Hardened tool steel ntawv

Cov ntawv hauv av ntawm stainless hlau

Nickel plated hnav nto

Hlau liners muab:

Siab hnav tsis kam

Dimensional stability nyob rau hauv load

nto hardness uniform

Ntev - lub sij hawm caij tsheb kauj vab ruaj khov nyob rau hauv kev rov ua dua

Tshwj xeeb Composite Liner
Engineered multilayer liners combining: Advanced applications yuav siv tau

Thermal kis txheej

Tso cov coatings

Kev txhawb zog txhawb nqa

Cov kev teeb tsa no raug xaiv rau cov kev xav tau ntau lawm.

Mechanical tsim ntawm liner txuas system
Clamping thiab Retention Techniques
Lub liner yuav tsum tau sib raug zoo thiab sib koom ua ke kom ua tau zoo thermal thiab mechanical kev ua tau zoo.

Txoj hauv kev yooj yim khaws cia suav nrog:

Peripheral bolt ntas

Ntug clamps T- qhov

Groove tuav systems (lub tshuab nqus tsev vacuum)

Magnetic backing systems (rau ferro-magnetic liners)

Nws yog ib qho tseem ceeb kom muaj lub siab txawm clamping kom tsis txhob:

Cov chaw huab cua hauv zos

Thermal kub qhov chaw

Nto deformation

Kev sib hloov tsis sib xws

Optimization ntawm Thermal Interface
Raws li lub liner yog ib txheej ntxiv ntawm cov cua sov platen thiab cov txheej txheem txheej txheem, thermal coupling yuav tsum tau ua tib zoo npaj.

Cov ntaub ntawv siv interface, suav nrog:

Thermal roj films

Graphite ntawv ci

Nyias daim ntawv ntawm cov hlau tiv tauj

Cov ntaub ntawv no txo ​​cov thermal tiv thaiv thiab txhim khu kev ua tau zoo ntawm kev hloov hluav taws xob hla lub interface.

Txawm li cas los xij, txawm tias muaj kev sib txuas zoo tshaj plaws, lub liner txhawb ntxiv thermal kuj yuav tsum tau muab coj los xav hauv kev tswj cov txheej txheem.

Thermal thiab txheej txheem cuam tshuam
Qhov cuam tshuam rau tus nqi cua sov
Lub tshav kub teb ntawm lub platen system yog hloov pauv los ntawm kev suav nrog cov kab tshem tawm.

Cov kev cuam tshuam tseem ceeb yog:

Ua kom muaj cua sov ua kom sov thaum tshav kub- nce

Me ntsis nce nyob rau hauv qhov ceev ntawm lub ncov saum npoo kub teb

Hloov PID tuning cov cai

Txias cwj pwm hloov thaum kaw

Rau fluoropolymer liners, thermal kuj yog siab dua rau cov hlau liners, yog li cov cua kub profiles yuav tsum tau calibrated ua tib zoo.

Qhov tseem ceeb ntawm qhov kub thiab txias
Qhov ntxiv thermal barrier yuav tsum tau them nyiaj los ntawm kev kho cov txheej txheem tswj cov txheej txheem.

Qhov no tuaj yeem suav nrog:

Lub sij hawm ntub dej ntev dua

Kev hloov pauv tus nqi nce

Re-calibration ntawm qhov kub thiab txias tawm tswv yim

Profile-raws li kev tswj cua sov

Qhov ntsuas kub qhov tseeb tuaj yeem sib txawv ntawm qhov chaw teeb tsa yam tsis muaj kev hloov kho, tshwj xeeb tshaj yog thaum lub sijhawm ua haujlwm ib ntus.

Engineering Design Specification Requirements
Surface Tolerancing thiab Flatness
Lub liner yuav tsum tiaj tus heev rau ib qho kev faib tawm ntawm lub siab.

Cov yam ntxwv tshwj xeeb muaj xws li:

Flatness kam rau ua rau tag nrho cov platen nto

Liner txheej ntawm uniform thickness

Surface roughness specification (raws li txheej txheem)

Repeatability tom qab ob peb lub voj voog ntawm kev teeb tsa

Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib npaug ntawm cov cua sov tuaj yeem tshwm sim los ntawm kev sib txawv ntawm qhov sib txawv.

Thermal Coupling Requirements
Tus qauv tsim interface yuav muab rau cov thermal sib tiv tauj thoob plaws platen nto.

Specification yuav tsum txhais: (a)

Txais tau cov ntaub ntawv interface

Maximum thermal tiv thaiv

Clamping quab yuam cov kev xav tau

Kev tso cai pib ntawm huab cua sib txawv (xws li xoom)

Cov txheej txheem rov ua tau zoo yuav tsum muaj kev sib txuas ntawm thermal coupling.

Kev tu thiab kev ua haujlwm zoo
Fast Changeover Capability
Replaceable liners muaj lub ntsiab kom zoo dua ntawm kev hloov pauv sai ntawm cov txheej txheem ntau lawm.

Cov txiaj ntsig: 1.

Kev cuam tshuam me me ntawm kev hloov pauv tseem ceeb

Tsawg tu ntawm lub hauv paus platen

Tshem tawm cov txheej txheem recoating

Txo - cov nqi tu lub sij hawm ntev

Surface Protection for Base Plate
Kev ruaj ntseg cua sov platen tiv thaiv:

Tshuaj tua rog.

Mechanical deterioration

Contaminated - Adhesive

Kev puas tsuaj los ntawm abrasive hais

Qhov no considerably prolongs lub neej ntawm cov tub ntxhais cua sov system.

Piv txwv ntawm Daim Ntawv Thov
Cov kev siv feem ntau ntawm cov kab hluav taws xob hloov tau muaj xws li:

Cov txheej txheem ntawm cov roj hmab molding

Composite curing khoom

Adhesive bonding method

Nias rau R & D

Ntau yam khoom siv prototyping

Txhua daim ntawv thov siv qhov zoo ntawm kev hloov pauv sai rau ntau yam khoom xav tau yam tsis muaj kev hloov kho vajtse.

Abstract
Lub kaw lus ntawm lub tshuab hluav taws xob hloov hluav taws xob cua sov platen ntau cov ntaub ntawv muab cov kev daws teeb meem yooj yim heev rau cov haujlwm uas xav tau kev hloov pauv ntau zaus hauv cov yam ntxwv ntawm kev sib cuam tshuam. Lub thermal muaj nuj nqi ntawm lub platen yog sib cais los ntawm nws cov txheej txheem kev sib cuag nto, tso cai rau ib tug cua sov chav tsev rau ob qho tib si tsis yog -stick, tshuaj tiv thaiv fluoropolymer liners thiab check metallic hnav nto.

Lub flatness yog ua tib zoo teev, lub thermal coupling mus kom ze thiab cov Symptoms txoj kev kom ib tug zoo ib yam ntawm cov tshav kub kis tau tus mob thiab cov neeg kho tshuab stability. Thaum cov txheej txheem tswj yuav tsum tau suav rau kev tiv thaiv thermal ntxiv, lub hauv paus platen muab sijhawm ntev heev - cov txiaj ntsig hauv kev ua haujlwm yooj yim thiab kev tiv thaiv.

Cov tshuab tsim tau yooj yim tshaj plaws yog cov uas tuaj yeem hloov kho tsis tau tsuas yog lawv cov txheej txheem, tab sis kuj lawv lub cev sib cuam tshuam nrog cov khoom siv, hauv cov ntsiab lus uas tso cai rau ib qho rhuab platen hloov nws tus kheej ua hauj lwm nto kom phim cov hauj lwm ntawm tes.
