Cov Kev Tsis Zoo ntawm Kev Luam Ntawv Gravure thiab Cov Kev daws teeb meem

Hauv cov txheej txheem luam ntawv mus sij hawm ntev, cov kua mem maj mam poob nws cov fluidity, thiab qhov viscosity nce ntxiv tsis zoo, uas ua rau cov kua mem zoo li jelly, Kev siv cov kua mem seem tom qab ntawd nyuaj dua.

Qhov laj thawj tsis zoo:

1, Thaum cov kuab tshuaj hauv cov kua luam ntawv tau volatilized, cov dej noo uas tsim los ntawm qhov kub qis sab nraud yog sib xyaw rau hauv cov kua luam ntawv (tshwj xeeb tshaj yog yooj yim tshwm sim hauv chav tsev uas kev siv cov kua luam ntawv me me heev).

2, Thaum siv cov kua mem uas muaj kev sib raug zoo nrog dej, cov kua mem tshiab yuav tuab zuj zus.

Cov Kev Daws Teeb Meem:

1, Yuav tsum siv cov tshuaj yaj sai sai kom ntau li ntau tau, tab sis qee zaum me ntsis dej yuav nkag mus rau hauv cov kua luam ntawv thaum qhov kub siab thiab noo noo. Yog tias muaj qhov tsis zoo tshwm sim, yuav tsum tau rov ua dua lossis hloov cov kua tshiab raws sijhawm. Cov kua seem uas siv ntau zaus yuav tsum tau lim lossis pov tseg tsis tu ncua vim muaj dej thiab hmoov av koom nrog.

2, Tham txog qhov tuab tsis zoo nrog tus neeg tsim khoom siv number case, thiab txhim kho cov qauv number case yog tias tsim nyog.

Tsw qab (cov kuab tshuaj seem): Cov kuab tshuaj organic hauv cov kua luam ntawv feem ntau yuav qhuav hauv lub tshuab ziab tam sim ntawd, tab sis cov kuab tshuaj seem yuav khov thiab hloov mus rau zaj duab xis qub kom nyob. Qhov ntau ntawm cov kuab tshuaj organic siab hauv cov ntawv luam tawm ncaj qha txiav txim siab qhov tsw ntawm cov khoom kawg. Seb nws puas txawv txav tuaj yeem txiav txim siab los ntawm kev hnia lub qhov ntswg. Tau kawg, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, kev hnia lub qhov ntswg tau poob qis heev. Rau cov khoom uas muaj qhov xav tau ntau dua rau cov kuab tshuaj seem, cov cuab yeej tshaj lij tuaj yeem siv los ntsuas lawv.

Qhov laj thawj tsis zoo:

1, Kev luam ntawv ceev dhau lawm

2, Cov khoom siv ntawm cov resins, cov khoom ntxiv thiab cov binders hauv cov ntawv luam tawm

3, Qhov ua kom qhuav qis dhau los yog txoj kev ziab tsis muaj

4, Cov pa cua raug thaiv

Cov Kev Daws Teeb Meem:

1. Txo qhov ceev ntawm kev luam ntawv kom tsim nyog

2. Qhov xwm txheej ntawm cov kuab tshuaj seem hauv cov kua luam ntawv tuaj yeem sib tham nrog cov chaw tsim kua kom ceev faj. Kev siv cov kuab tshuaj qhuav sai tsuas yog ua rau cov kuab tshuaj qhuav sai, thiab tsis muaj ntau yam cuam tshuam rau kev txo cov kuab tshuaj seem.

3. Siv cov tshuaj yaj uas qhuav sai lossis ziab kub tsawg (qhuav sai yuav ua rau saum npoo ntawm cov kua mem tawv, uas yuav cuam tshuam rau kev ua kom cov tshuaj yaj sab hauv qhuav. Kev ziab qeeb qeeb yuav ua rau txo cov tshuaj yaj seem.)

4. Vim tias cov organic solvent seem kuj muaj feem cuam tshuam nrog hom zaj duab xis thawj, qhov ntau ntawm cov tshuaj seem sib txawv nrog hom zaj duab xis thawj. Thaum tsim nyog, peb tuaj yeem tham txog qhov teeb meem ntawm cov tshuaj seem nrog cov thawj zaj duab xis thiab cov chaw tsim kua mem.

5. Ntxuav cov kav dej kom huv si kom nws tawm tau zoo
