Txoj kev npaj thiab teeb meem ntawm aluminium npuas sandwich panels

Kev npaj ntawmaluminium sandwich vaj huam sib luagmuab faib ua ob pawg tag nrho. Thawj qeb yog npaj cov txhuas ua npuas ncauj ua ntej, thiab tom qab ntawd txuas cov txhuas ua npuas ncauj nrog cov hlau vaj huam sib luag hauv ntau txoj kev, xws li cemented kev twb kev txuas, nto thermal spraying txoj kev, thiab vuam kev twb kev txuas. Qhov thib ob yog los npaj lub prefabricated lub cev ntawm aluminium foam sandwich vaj huam sib luag, thiab tom qab ntawd lub prefabricated lub cev yog rhuab los ua cov txheej txheem ua npuas ncauj, thiab cov npuas dej txias tom qab ua tiav ntawm cov npuas dej uas yog aluminium foam sandwich vaj huam sib luag. Feem ntau siv txoj kev npaj muaj xws li kub nias - hmoov metallurgy foaming txoj kev, dov - txheej - foaming txoj kev, thiab hais txog.

1. Glued kev twb kev txuas

Gluing yog hais txog cov txheej txheem ntawm kev ua cov sandwich panels los ntawm kev sib txuas ntawm txhuas ua npuas ncauj rau hlau panels nrog cov nplaum tsim nyog. Cov txheej txheem gluing tau txais kev sib txuas ntawm lub cev los npaj lub vaj huam sib luag sandwich, thiab cov txheej txheem muaj qhov zoo ntawm cov txheej txheem yooj yim thiab siab ntau lawm precision. Txawm li cas los xij, vim yog cov yam ntxwv ntawm lub siab porosity ntawmaluminium ua npuas ncauj, tshem tawm cov impurities nyob rau hauv lub qhov nyob rau saum npoo ntawm aluminium npuas yog hnyav heev; nyob rau hauv txoj kev sib txuas no, lub vaj huam sib luag thiab cov txheej txheem tseem ceeb feem ntau yog glued ntawm lub aperture prongs, thiab qhov tseeb qhov sib txuas ntawm qhov chaw me me, uas ua rau muaj kev sib txuas ntawm lub zog ntawm cov qhaub cij; cov nplaum tsis ua haujlwm ntawm qhov kub thiab txias los yog nyob rau hauv qhov chaw muaj zog corrosive, uas ua rau kev sib cais ntawm cov tub ntxhais txheej ntawm lub vaj huam sib luag thiab kev puas tsuaj ntawm cov qauv.

2. Kev sib txuas ntawm vuam

Vuam txoj kev rau kev npaj ua npuas ncauj aluminium sandwich panels muaj xws li laser beam welding, ultrasonic torsion vuam, thiab kev sib txuas brazing. Laser beam welding yog siv lub laser lub siab thermal zog rau vaj huam sib luag cov ntaub ntawv thiab ua npuas ncauj aluminium nto txheej melting, txias tom qab ob qho tib si ua ke, qhov chaw vuam txoj hauj lwm, thiab vuam ib ntus qhia nyob rau hauv daim duab 1. Laser beam welding yog heev raug thiab ua tau zoo. tswj thaj tsam melted sib koom. Txawm hais tias txoj kev no tuaj yeem ua tiav kev ua haujlwm tas mus li, qhov ua tau zoo yog tsawg, thiab cov khoom lag luam daim ntawv cog lus muaj zog kuj tsawg. Lub hauv paus ntsiab lus ntawm ultrasonic torsion vuam yog koom nrog ob cov ntaub ntawv ua ke los ntawm lub zog ultrasonic. Txawm li cas los xij, txoj kev no yuav tsum muaj qee qhov chaw vuam, thiab nws tsis tuaj yeem ua tiav qhov vuam ntawm txhua qhov chaw ntawm lub hom phiaj, uas txwv kev siv cov qauv no hauv kev tsim khoom tiag tiag. Lub brazing kev twb kev txuas yuav raug cuam tshuam los ntawm oxidized txheej ntawm ua npuas ncauj aluminium, yog li nws yog ib qho tseem ceeb kom tshem tawm cov oxidized txheej, thiab thaum siv brazing tshuab tsis muaj brazing flux hauv.ua npuas ncauj aluminiumSandwich panels, qee qhov kev tiv thaiv corrosion yuav tsum tau coj mus rau hauv tus account kom tiv thaiv zinc-based thiab lwm yam alloys los ntawm kev sib txuas nrog txhuas corrosion. Tsis tas li ntawd, qhov chaw txuas los ntawm txoj kev no tsuas yog muaj qhov prongs, yog li lub zog ntawm daim ntawv cog lus yuav raug txo.

3. Nto thermal txau txoj kev

Cov txheej txheem txheej feem ntau yuav tsum tau muaj kev sib tw siab ntawm qhov chaw ntawm cov khoom, yog li cov txheej txheem tsis haum rau ntau cov qauv. Thermal spraying belongs rau ib tug nto technology, uas yog paub los ntawm melting xov hlau los yog hmoov. Txoj kev no siv lub dav hlau ntawm huab cua kom nrawm cov khoom siv yaj thiab hloov mus rau saum npoo ntawm cov khoom kom coated, ua rau kev ua cov khoom siv nrog cov duab nyuaj. Nyob rau hauv txoj kev no, lub tshav kub qhov chaw feem ntau yog hluav taws xob arc. Txawm li cas los xij, txoj kev no nyuaj rau kev lag luam vim qhov nyuaj ntawm cov txheej txheem.

4. Kub nias - hmoov metallurgy foaming txoj kev

Nyob rau hauv txoj kev no, cov tub ntxhais txheej hmoov siv rau foaming yog thawj zaug muab tso rau hauv lub vaj huam sib luag, thiab tom qab ntawd lawv muab tso rau hauv pwm ua ke, thiab hydraulic xovxwm yog siv los thov txias siab rau lawv, tom qab ntawd cov blanks tau tuav ntawm 450 ℃. rau li 1 h thiab ces kub nias kom tau cov prefabricated blanks uas yuav ua tau rau foaming. Lub preform yog ces rhuab thiab foamed nyob rau hauv ib tug kaw pwm, thiab lub sandwich vaj huam sib luag yog tau tom qab txias. Lub xub ntiag ntawm cov pwm nyob rau hauv txoj kev no yuav muaj qee qhov kev txwv ntawm qhov loj ntawm qhov ua tiav ntawm aluminium npuas sandwich vaj huam sib luag.

5. Rolling-coating-foaming method

Txoj kev no yog cov hmoov qub rau foaming siv qhov tsim nyog dov txhais tau tias yuav ua rau cov khoom siv tseem ceeb, tom qab lub vaj huam sib luag thiab cov khoom siv prefabricated rau dov, txheej, kom tau txais cov prefabricated blanks, foaming tom qab txias kom tau ib tug zoo qauv ntawm cov qhaub cij. vaj huam sib luag. Cov txheej txheem ntawm kev npaj cov khoom uas muaj kev sib raug zoo siab tuaj yeem paub qhov kev tsim khoom tas mus li tab sis yuav tsum tau kov yeej ob txoj kev nyuaj: ib qho yog qhov yuav tsum tau ua kom cov hmoov densify, thiab qhov thib ob yog kev sib xyaw ua ke ntawm cov khoom tseem ceeb thiab vaj huam sib luag dov.
