Yuav ua li cas kom tsis txhob muaj lub npuas ua pa thaum lub ntsej muag ci
Cov khoom siv tshuab gluing yog cov khoom siv kho tshuab siv rau gluing. Cov cuab yeej siv no tuaj yeem paub qhov kev sib xyaw tsis siv neeg thiab kev faib ua ob-tivthaiv kua nplaum. Rau cov kua nplaum tswj kev xav tau ntawm qee qhov ua haujlwm siab ua haujlwm, cov kua nplaum yuav tsum tau kho xau. Qhov teeb meem ntawm cua npuas hauv cov txheej txheem ci ntsa iab ntawm lub tshuab ci.
Lub tshuab gluing tshuab ua kom muaj npuas thaum lub tshuab ci. Yuav daws tau cov teeb meem no li cas? Qhov laj thawj ntawm npuas los cuam tshuam rau cov kua nplaum thiab cov pa nkag thaum lub sijhawm ua haujlwm. Ntawm no mas qhia txog kev daws teeb meem npuas ntawm epoxy resin kua nplaum. Epoxy resin kua nplaum feem ntau hais txog cov nplaum ua nrog epoxy resin ua lub cev lub cev, thiab epoxy resin kua nplaum yuav tsum muaj feem ntau epoxy resin ua kua tshuaj tus neeg sawv cev, txwv tsis pub cov kua nplaum yuav tsis tuaj yeem kho.
Cov npuas tom qab kho yuav tsum tau tshawb xyuas los ntawm ob qho: ib qho yog cov npuas qhia thaum lub sijhawm hloov kua nplaum lossis txheej txheem ci, thiab lwm qhov yog cov npuas tsim tawm thaum lub sijhawm ua cov txheej txheem kho.
Thaum lub sij hawm kho cov kua nplaum txheej txheem, huab cua tau yooj yim nqa mus rau hauv cov kua nplaum vim muaj qhov siab viscosity ntawm kua nplaum lossis kev tsis haum rau kev sib xyaw. Yog tias cov kua nplaum muaj cov viscosity siab, cov npuas yuav nyuaj rau tshem tawm.
Yog tias lub kua nplaum viscosity me me, yog tias cov kua nplaum kho kom maj mam, cov npuas yuav maj mam sawv rau saum npoo thiab ploj mus. Txhawm rau tshem tawm cov npuas hauv cov txheej txheem kev sib dhos thiab txhaws, nqus tsev, cua sov kom txo viscosity, ntxiv cov teeb meem kom txo viscosity, lossis ntxiv cov defoamers, thiab lwm yam tuaj yeem siv los tshem tawm cov npuas.
Muaj ntau lub laj thawj rau cov npuas hauv cov txheej txheem kho: ceev dhau ntawm kev kho lub nrawm, siab kub dhau lawm, qhov loj ntawm txoj kev kho cov kua nplaum tsis txaus, ntau dhau ntawm cov kuab tshuaj rau hauv cov kua nplaum, thiab ntau dhau ntawm cov kua nplaum yog txhua yam yuav tsim npuas thaum lub sijhawm ua cov txheej txheem kho.
Peb yuav ua li cas peb thiaj li tsis tuaj yeem tiv thaiv npuas?
Hauv kev tsim qauv ntawm lub tshuab ua gluing, kev siv tau ntawm cov kua nplaum yog qhov tseem ceeb. Yog li, thiaj li daws qhov teeb meem ntawm huab cua npuas lub sijhawm gluing, lub tshuab ci lub ntsej muag siv txoj kev nqus thiab theem kev sau, thiab cov kua nplaum tso rau hauv lub taub dej siab. Lub tshuab nqus tsev tuaj yeem tiv thaiv kom tsis txhob muaj npuas nyob hauv cov kua nplaum. Kev sib zog, kev ua kom sov, nqus thiab lwm yam haujlwm ntxiv rau cov kua nplaum tso kua mis, uas tuaj yeem tso cov roj tag nrho rau hauv cov kua nplaum thiab xyuas kom meej qhov zoo thiab qhov xav tau ntawm lub tuam txhab' s ntau lawm.
