Tswj cov ntsiab lus ntawm cov kuab tshuaj-dawb

Abstract: Cov kab lus no feem ntau qhia txog kev tswj cov ntsiab lus ntawm cov txheej txheem kev tswj hwm, ntsuas qhov ntsuas kub, tswj cov av noo thiab nws cov khoom siv, kua nplaum preheating, thiab lwm yam.

Cov kuab tshuaj pub dawb muaj ntau zuj zus, thiab yuav ua li cas siv cov txheej txheem no yog cov ncauj lus ntawm kev txhawj xeeb rau txhua tus. Txhawm rau siv cov kuab tshuaj dawb, tus sau tau pom zoo tias cov khoom siv sib txuas lus lossis cov kua nplaum ob npaug rau cov qauv khoom lag luam feem ntau ntawm cov qauv khoom lag luam, Thiab lwm yam kev xaiv cov nplaum uas haum rau cov npoo lossis sab hauv raws li kev pab ntxiv raws li cov neeg siv khoom tus qauv.

Cov txiaj ntsig ntawm kev siv ob lub tog raj roj hmab ob lub tog raj kheej yog: nws tuaj yeem nce cov ntawv thov ntau cov tshuab sib xyaw, txo tus nqi, thiab muaj txiaj ntsig tsawg, thiab ua haujlwm siab. Thiab tsis muaj ib qho yuav tsum tau ntxuav kom ntau zaus kom nquag plias lub tog raj kheej, mus hloov cov nplaum, thiab txo cov pov tseg. Koj tseem tuaj yeem xaiv cov nplaum nplaum raws cov khoom lag luam thiab cov neeg siv khoom kom cov khoom lag luam zoo.

Hauv cov txheej txheem ntawm kev pabcuam cov neeg siv khoom ntev ntev, Kuv kuj tau sau cov txheej txheem tswj qee cov txheej txheem uas yuav tsum tau them sai sai uas yuav tsum tau them nyiaj rau kom thiaj li ua tau txoj haujlwm zoo hauv cov kuab tshuaj zoo.

1.Cov qab

Yuav kom ua tiav cov kuab tshuaj pub dawb, thawj zaug ua yog huv, uas tseem yog qhov taw tes yooj yim los ntawm cov lag luam.

Kev ruaj khov rau cov menyuam, ntsuas cov menyuam yaus, cov lus qhia ntau dua rau cov menyuam yaus, nrog rau cov niam txiv siab, yuav tsum huv si thiab tsis muaj cov khoom lag luam txawv teb chaws, Vim tias muaj ib qho khoom txawv txawv hauv cov cheeb tsam no yuav ua rau npuas thiab dawb me me rau saum npoo ntawm cov yeeb yaj kiab sib xyaw.

2.Txoj kev tswj

Cov khoom tseem ceeb ntawm cov kuab tshuaj nplaum dawb yog NCO, thaum lub sij hawm kho tus sawv cev yog huag. Qhov ceev, viscosity, kev ua haujlwm ntawm cov neeg sawv cev tseem ceeb thiab cov khoom noj kom sov, thiab lub sijhawm ntawm cov nplaum, thiab txhua lub sijhawm cuam tshuam rau qhov zoo ntawm cov composite.

Cov kuab tshuaj dawb Polyurethane nplaum muaj siab viscosity ntawm qhov tsis muaj cov tshuaj tua menyuam, thiab kev tsim cov kev sib txuam ntawm hydrogen. Cov cua sov tuaj yeem ua kom zoo txo ​​vepcosity, tab sis ntau dhau high heperate tau yooj yim coj los ua gelation, tsim coating hnyav, ua co kom nyuaj lossis tsis sib luag. Yog li ntawd, tswj tau txheej txheej kub yog qhov tseem ceeb heev.

Feem ntau, cov khoom lag luam nplaum yuav muab cov neeg siv khoom siv nrog qee qhov kev siv nyiaj uas yog siv, thiab siv tus nqi ntau.

Qhov kub siab dua ua ntej sib tov, qhov qis dua viscosity; Qhov siab dua qhov kub tom qab sib tov, ntau dua qhov viscosity.

Qhov ntsuas kub kho tau ntawm cov kev ntsuas cov menyuam thiab cov menyuam txheej feem ntau yog nyob ntawm viscesive ntawm cov nplaum. Qhov ntau dua cov viscosity ntawm cov nplaum, qhov siab dua qhov ntsuas kub ntawm cov menyuam ntsuas. Qhov ntsuas kub ntawm cov menyuam yaus sib xyaw feem ntau yuav tswj tau ib puag ncig 50 ± 5 ° C.

3.glue kev tswj hwm

Raws li cov ntaub ntawv sib txawv, cov kua nplaum sib txawv tuaj yeem siv tau. Raws li muaj nyob hauv lub rooj, kwv yees li ntawm cov roj nplaum ntau tau muab, thiab kev tswj cov kua nplaum tau yog feem ntau sib piv ntawm cov menyuam ntsuas thiab cov menyuam sib kho.Cov ntawv thov kua nplaum

4.pressure tswj

Vim yog qhov tseeb tias cov txheej txheej ntawm cov me nyuam cov roj pleev cov khoom siv ntawm ob lub teeb sib piv, qhov loj ntawm txheej siab yuav cuam tshuam rau cov kua nplaum cov kua nplaum. Qhov siab dua lub siab, tus me dua cov kua nplaum siv.

5.Qhov sib xyaw ntawm number case thiab lo kua nplaum

Qhov sib raug zoo ntawm cov kuab tshuaj nplaum dawb thiab inks feem ntau zoo tam sim no. Txawm li cas los xij, thaum cov tuam txhab hloov pauv cov khoom lag luam lossis cov khoom sib txuas, lawv tseem yuav tsum tau kuaj kev sib xws.

6.Qhov tswj hwm

Nro tswj yog qhov tseem ceeb hauv cov kuab tshuaj dawb vim tias nws cov ntawv nplaum pib yog qhov tsawg heev. Yog hais tias qhov nro ntawm sab xub ntiag thiab nraub qaum tsis phim, muaj qhov ua tau tias thaum lub ntsej muag muaj sib txawv, ua rau cov tsos ntawm npuas thiab ntau.

Feem ntau, kev pub mis thib ob yuav tsum tau txo kom ntau li ntau tau, thiab rau cov yeeb yaj kiab tuab, lub nro thiab qhov kub thiab txias thiab kub nce ntxiv. Sim ua kom tsis txhob curling ntawm cov yeeb yaj kiab sib xyaw kom ntau li ntau tau.

7.Cov av noo thiab nws ib puag ncig

Kev saib xyuas tsis tu ncua ntawm cov av noo thiab kho qhov sib piv ntawm tus neeg sawv cev tseem ceeb thiab tus kws kho tus sawv cev raws li. Vim tias qhov nrawm nrawm ntawm kev sib xyaw ua ke, yog tias cov av noo siab dhau, siv qee qhov ntswg xws li lo kua nplaum tsis ziab thiab tsis zoo tev.

Vim yog cov kev kub ceev ntawm cov kuab tshuaj dawb laminating, lub substrate siv yuav tsim hluav taws xob yooj yim thiab impurities, cuam tshuam cov tsos zoo ntawm cov khoom. Yog li ntawd, kev ua haujlwm ua haujlwm ntau lawm yuav tsum raug kaw, ua kom lub rhiav hauv qhov ntsuas kub thiab av noo ntau.

8glue preheating

Feem ntau, cov kua nplaum ua ntej nkag mus rau hauv lub tog raj kheej yuav tsum tau ua ntej, thiab cov kua nplaum sib xyaw tsuas yog siv tau tom qab qhov ntsuas kub kom ntseeg tau tus nqi hloov.

9.Corconclusion

Nyob rau hauv cov theem tam sim no uas cov kuab tshuaj yeeb yaj kiab thiab cov khoom sib xyaw qhuav thiab cov khoom lag luam qhuav yuav tsum tau siv cov khoom siv thiab cov txiaj ntsig zoo. Cov txheej txheem tuaj yeem yog cov tshuaj tiv thaiv-dawb, thiab nws yuav tsis muaj kev sib xyaw qhuav. Tsim nyog thiab npaj tau ntau lawm, thiab siv tau zoo siv cov khoom siv uas twb muaj lawm. Los ntawm kev tswj cov txheej txheem thiab tsim cov phau ntawv ua haujlwm ua haujlwm, tsis muaj peev xwm ua tau los txo qis.
