Nrog rau kev nthuav dav ntawm lub thawv lag luam, muaj ntau thiab ntau lub thawv ua tsis muaj lub thawv xaj lub tshuab, vim tias lub thawv xaj yuav ua rau cov khoom puas hauv. Yog li ntawd, lub tshuab ua kua nplaum yog ib qho tseem ceeb ntawm cov khoom siv hauv lub thawv ntim khoom, thiab tom qab ntawd feem ntau muaj qee qhov teeb meem thaum gluing lub thawv, yog li cia peb saib yuav ua li cas daws lawv.
1. Kev sib txuas ceev ceev tsis siab, thiab lub thawv yog degummed.
Degumming yog hais txog kev tawg ntawm lub qhov ncauj nplaum vim tsis muaj kev sib txuas ceev ceev. Cov laj thawj tseem ceeb tau sau tseg raws li hauv qab no:
(1) Lub viscosity ntawm cov nplaum tsis txaus lossis cov kua nplaum siv tsis txaus.
(2) Cov nplaum thiab cov khoom ntim tsis sib xws.
(3) Lub qhov ncauj nplaum ntawm lub thawv tau ua tiav los ntawm lamination thiab glazing. Nws yog qhov nyuaj rau cov nplaum kom nkag mus rau hauv cov txheej txheej saum npoo thiab nkag mus rau hauv daim ntawv, thiab lub thawv ntawv nyuaj rau lo.
(4) Lub siab tom qab folding thiab gluing yog tsis txaus, thiab lub sij hawm nias tsis ntev txaus, uas tsis haum rau lub zog muab tshuaj txhuam.
Rau cov teeb meem saum toj no ntawm kev ua tsis zoo los ntawm cov nplaum nplaum, cov nplaum tsim nyog rau cov khoom ntim yuav tsum raug xaiv, thiab kev xaiv thiab siv cov nplaum kuj tseem ceeb heev.
Ua ntej tshaj plaws, nws tsis tuaj yeem ntseeg tau tias qhov siab dua qhov viscosity ntawm cov nplaum, qhov zoo dua qhov gluing nyhuv. Qhov siab dua qhov viscosity, qhov siab dua lub zog nplaum thiab qhov siab dua qhov wrinkling. Thaum cov kua nplaum nplaum ntawm cov ntaub ntawv tsis siv neeg lub nplaum nplaum khiav ntawm qhov ceev ntawm 112 revolutions ib feeb, qhov pom zoo viscosity ntawm cov nplaum yog 500-1000cps.
Qhov thib ob, lub zog nplaum ntawm cov nplaum yog muaj zog dua. Vim tias lub siab ceev ntawm txoj kev tsim ib feem ntawm qhov tsis siv neeg cov ntawv nplaum nplaum tsis loj heev, thiab thaum lub sijhawm ua haujlwm siab ntawm kev tsim 30-40 cartons ib feeb, lub sij hawm siab tsis ntev. Kev siv lub siab kuj tuaj yeem khi lub thawv ruaj khov.
Tsis tas li ntawd, qhov kub thiab txias ntawm lub rooj cob qhia gluer kuj yuav muaj qee yam cuam tshuam rau cov nplaum. Yog tias qhov kub thiab txias ntawm qhov kev cob qhia pasting tsawg dhau lawm, cov nplaum nplaum yuav khov tam sim ntawd, cuam tshuam rau kev sib txuas ceev, txawm tias cov kua nplaum siv ntau dhau, nws yuav tsis ua haujlwm. Yog lawm, cov kua nplaum tsawg dua yog siv rau hauv chav tsev kub, yog li nyob rau lub caij ntuj no, qhov kub ntawm cov nplaum nplaum yuav tsum khaws cia siab tshaj 20 ° C, thiab cov cua txias tuaj yeem ntsia tau yog tias muaj kev tso cai.
Nyob rau hauv cov ntaub ntawv-gluing Rhiav, tus pas ntsuas kub loj thiab pom tau yooj yim kuj tau teeb tsa los xyuas thiab tswj qhov chaw ua haujlwm txhua lub sijhawm. Rau cov khoom pasted, lawv yuav tsum tau qhuav ntawm chav tsev kub ua ntej tawm hauv lub hoobkas. Thaum lub caij ntuj no, tsis txhob maj xa cov khoom ua ntej lawv qhuav.
Rau lub thawv uas tau npog thiab varnished, muaj 4 txoj hauv kev los daws qhov teeb meem ntawm lub thawv nplaum:
Ua ntej, muab ib rab koob thiab xov riam ntawm lub qhov ncauj nplaum thaum lub sij hawm txiav tuag kom puncture ntawm lub qhov ncauj nplaum los pab txhawb kev nkag mus ntawm cov nplaum.
Thib ob, siv cov cuab yeej edging txuas nrog lub tshuab tsis siv neeg lub nplaum nplaum kom zom qhov chaw ntawm lub qhov ncauj nplaum los pab txhawb kev nkag mus ntawm cov nplaum.
Thib peb, cov nplaum nplaum kub yog txau rau ntawm qhov ncauj qhov ncauj, thiab cov khoom ntawm lub qhov ncauj qhov ncauj yog melted ntawm qhov kub thiab txias los txhim kho qhov ceev ntawm lub thawv kua nplaum.
Plaub, thaum tsim lub thawv ntawv ua ntej luam ntawv, koj tuaj yeem tso ib qho gluing rau ntawm ntug ntawm lub thawv kom npog thiab varnished ua ntej.
Rau qhov tshwm sim uas lub nplaub tshev tsis muaj zog vim tsis txaus siab, koj tuaj yeem ua rau kom lub siab ntawm qhov nias ntawm lub nplaub tshev gluer, ncua lub sij hawm nias, los yog hloov cov nplaum uas muaj zog adhesion.
2. Deformation ntawm lub thawv
Muaj peb lub ntsiab yog vim li cas rau deformation ntawm lub thawv:
(1) Qee cov ntawv txiav tuag yog tsim los ntawm tes, thiab qhov loj ntawm lub thawv feem ntau tsis sib haum vim tsis muaj qhov tseeb, thiab lub thawv yog deformed thaum lub thawv muab tso rau.
(2) Lub concentration ntawm cov nplaum yog tsawg thiab cov ntsiab lus dej yog loj, uas ua rau cov duab los qhia kom nqus dej noo thiab deform, thiab lub thawv tsis tiaj tom qab tsim.
(3) Lub nplaub tshev gluer nws tus kheej tsis kho zoo.
