Yuav Ua Li Cas Loj PTFE Exchanger rau Ob -Phase Boiling Daim Ntawv Thov ntawm Tube Sab?

Tej zaum yuav tsis xav tau ib lub rooj sib txoos tshiab yog tias nws hloov PTFE tubing tuaj yeem ua pob tw - fusion welded rau nws tus kheej los ntawm kev ua tib zoo tswj xyuas kom tsim tau cov qauv polymer txuas ntxiv uas tsis muaj cov nplaum lossis cov khoom muab tub lim. Ib txoj hlua ua kom raug yog qhov sib txawv ntawm cov raj qub uas ua rau muaj kev sib raug zoo siab rau kev ua haujlwm hnyav.

Butt fusion weld kho ntawm tawg PTFE raj sib dhos yog siv dav hauv kev tsim cov tshuab fluoropolymer. Txawm li cas los xij, kev kho thaj chaw yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev tswj xyuas nruj.

Butt-Fusion Vuam rau PTFE Tubes: Nws Ua Haujlwm Li Cas
Butt- fusion vuam siv cua sov los ua kom qhov kawg ntawm ob lub kav dej thermoplastic los txuas lawv ua ke. Cov npoo molten raug coj los ua ib qho kev sib txuas.

Cov txheej txheem no tsim ib homogeneous daim ntawv cog lus ntawm polymer chains ntawm ob lub ntsiab lus, as opposed to mechanical couplings or adhesive fixes.

Yuav Ua Li Cas Polymer Bond Forms
PTFE yog ib nrab -crystalline polymer. Rau welding:

Cov crystalline feem melted nyob rau hauv tswj kub.

Polymer saw txav ntawm qhov chaw

Cov npoo yog nias ua ke, softened

Molecular interdiffusion tshwm sim thoob plaws lub interface

Thaum nws txias, qhov sib koom ua ib homogenous qauv.

Yog tias ua tiav lawm, qhov vuam yuav tsum ploj mus rau hauv lub raj tsuas yog me ntsis fusion hlaws rau sab nraud los qhia txog kev sib koom ua ke.

Butt- fusion vuam txheej txheem kauj ruam -los ntawm - kauj ruam
Kev vam meej welding feem ntau yog qhov zais cia ntawm kev npaj kom raug thiab cov txheej txheem vuam.

Tube End Kev Npaj
Ua ntej ib tug yuav tsum tau ua tib zoo npaj ob kawg ntawm lub raj.

Square txiav yog qhov yuav tsum tau!
Qhov kawg ntawm lub raj yog square txiav, ntawm txoj cai kaum rau lub raj axis. Qhov me me angular misalignment tuaj yeem tsim tau:

Cov cua sov tsis sib xws

Tiv tauj nyob rau hauv qis qis

Internal hollowness

Tsis muaj zog cheeb tsam ntawm fusion

Cov cuab yeej tshwj xeeb txiav feem ntau yog siv los tswj qhov ntev kom zoo.

Ntxuav Cov Nto
Qhov kawg ntawm lub raj yog ces ntxuav kom zoo kom tshem tawm:

Qhov av

Yog '0

Kev tiv thaiv oxidation

Ua cov khoom pov tseg.

Moisture

Cov kab mob kis tau los ntawm kev sib cuag fusion tuaj yeem ua rau lub vuam zoo heev.

Cua sov PTFE Surfaces
Cov yeeb nkab kawg yog nias tawm tsam ib lub phaj rhuab fusion thaum lawv tau ua raws li kev sib tw vuam.

Phaj tswj qhov kub thiab txias
Feem ntau cov phaj kub yog:

Kub: nruj tswj

PTFE txheej rau tsis- nplaum

Raws li ib tug tube khoom specification

Vuam kub rau PTFE yog txwv thiab cov khoom rhiab heev. Lub voj voog yuav tsum tau tswj kom zoo.

Thaum lub raj kawg cua sov:

Cov crystallites soften, liquefy.

Plasticized nto

Lub circumference pib liquefy mus rau hauv ib tug hlaws dai,

Qhov loj thiab qhov pom ntawm cov hlaws no yog cov ntsiab lus tseem ceeb rau txoj cai yaj lub xeev.

BONDING THIAB FUSION
Thaum lub sij hawm mus txog qhov xav tau melt condition:

Kev tshem tawm ceev phaj

Cov qhov muag muag ntawm cov raj yog ces thawb ua ke

Tswj kev xa khoom ntawm axial siab

Nws yog khaws cia rau hauv qhov chaw kom txog thaum lub sib koom ua ke txias.

Qhov theem no tso qhov kawg kev ncaj ncees rau ntawm qhov vuam.

Kev Tswj Siab yog qhov tseem ceeb
Lub zog ntau dhau tuaj yeem suav nrog:

Molten tshuaj txaws

Weld Zone B. Thinning

Ua si nrog lub raj zoo

Tsawg siab tuaj yeem tawm mus;

Digs

Ib nrab melting

Me me molecular cohesion

Yog li kev tswj xyuas qhov tseeb yog lub hauv paus ntawm tag nrho cov txheej txheem fusion.

Solidification thiab txias
Tom qab ntawd lub raj yog clamped nyob rau hauv qhov chaw thiab cov khoom tso cai rau txias thiab recrystallise.

Tsis txhob cuam tshuam nrog kev tswj kom txias
Kev txias txias nrawm los yog tsis sib xws yuav ua rau:

Residual stress

Distortion

Qhov tsis xws luag hauv cov siv lead ua

txo weld zog

Kev sib koom ua ke kawg yog tsim los nrog qhov zoo tshaj plaws tsim rau nws kom muaj cov yam ntxwv ntawm cov niam txiv tube nws tus kheej los ze zog.

Yog li ntawd yuav tsum muaj kev tsim nyog ntawm cov txheej txheem.

Vim li cas PFA yooj yim dua rau vuam feem ntau
PFA feem ntau suav hais tias yooj yim dua rau vuam tab sis pob tw fusion ntawm PTFE yog ua tau.

Qhov zoo ntawm melt processability
Txawm li cas los xij, PFA yog tag nrho yaj-ua tau nrog yaj- ua cov cwj pwm yooj yim dua li PTFE uas muaj kev hloov pauv crystallinity ntau dua ntawm cov cua sov.

Yog li ntawd:

PFA fusion windows yog tswj tau ntau dua.

Zoo dua weld sib xws.

Txhim kho nto tiav

Cov ntawv thov uas xav tau purity siab yog cov txiaj ntsig

Yog li PFA yog dav siv nyob rau hauv tsis tshua muaj siab purity semiconductor thiab tshuaj ua tshuab uas yuav tsum tau welded fluoropolymer kev twb kev txuas.

Feem ntau yog vim li cas rau fusion weld tsis ua haujlwm
Muaj ntau lub ntsiab lus tuaj yeem cuam tshuam qhov zoo ntawm qhov weld.

Kub yuam kev
Yog tias qhov ntsuas kub tsawg dhau qhov kev sib tshuam ntawm cov molecules tsis ua haujlwm zoo txaus, thiab yog tias qhov kub thiab txias siab dhau lawm, cov polymer tuaj yeem tawg.

Kev tsis ncaj ncees
Lub misalignment ntawm cov hlab ua rau inhomogeneous kev nyuaj siab faib nyob rau hauv weld cheeb tsam.

Cov pa phem 2.
Cov teeb meem txawv teb chaws ntawm lub interface cuam tshuam kev sib txuas ntawm polymer.

Tsis txaus lub sijhawm txias
