Raws li paub rau txhua tus, silk screen tshuab luam ntawv yog cov cuab yeej tseem ceeb ntawm kev lag luam luam ntawv yuav tsum siv, tam sim no kev lag luam yog ntau thiab loj dua, leej twg tsis tuaj yeem lav qhov zoo ntawm kev luam ntawv, silk screen luam ntawv tshuab yog tias peb xav tau lav cov luam ntawv. zoo ntawm cov ntaub ntawv luam tawm thiab cov khoom siv luam ntawv los ua qhov kev xaiv zoo, ces yuav ua li cas thiaj li ua tau zoo luam ntawv zoo npo luam ntawv xovxwm?
Screen luam ntawv tshuab
1, screen positioning
Cov khoom siv kho mob siv hauv lub Hoobkas no suav nrog hlau, ntoo, plywood thiab pob tshab PVC nplooj ntawv.Yog tias nyuaj rau nrhiav, substrate loj thiab me me, koj yuav tsum xaiv cov khoom siv hlau.Yog tias cov ntawv thiab cov ntawv nyob ze rau ntawm ntug substrate, yuav tsum tau kho ntawm ib sab ntawm lub substrate thiab substrate ntug raws li lub dav hlau siab, kom tsis txhob yooj yim muab tshuaj txhuam cov ntawv thiab cov ntawv.Qhov kev ncua deb yog feem ntau 1.0 ~ 2.5mm.Yog tias cov qauv luam ntawv yooj yim rau paste lossis muaj mesh, yuav tsum tau kho qhov screen nrug.
2, xaiv qhov screen
Qhov zoo ntawm cov ntaub lo lo ntxhuav yog ruaj khov nrog cov kab uas hla tsis sib xws thiab cov xov tooj raug.Feem ntau xaiv mesh yog 450 ~ 500 mesh.Cov kab zoo, number case fineness, nqus ntawm substrate, koj yuav tsum xaiv ib tug siab mesh tooj screen, ntawm qhov tsis tooj, koj yuav tsum xaiv ib tug tsawg mesh tooj screen.
Phaj-ua cov duab thiab cov ntawv ntawm lub vijtsam thiab qhov screen loj yuav tsum yog raws li cov qauv substrate, qhov loj thiab cov duab substrate thiab cov ntawv ntawm qhov chaw.Yog tias tus qauv tsim tsis zoo, nws yuav cuam tshuam rau qhov zoo ntawm kev tshuaj ntsuam luam ntawv, txawm tias tsis tuaj yeem tshuaj ntsuam luam ntawv.Tsis tas li ntawd, tib cov duab thiab cov ntawv nyeem ntawm kev luam ntawv, nws yog qhov zoo tshaj plaws los siv lub vijtsam luam ntawv.Yog tias muab faib ua ob rau kev tshuaj ntsuam luam ntawv, cov txheej txheem yuav txo qis tus nqi tsim nyog ntawm kev tshuaj ntsuam luam ntawv.
3, xaiv cov hniav
Feem ntau ntawm cov khoom siv yog polyurethane.Polyurethane roj hmab hniav muaj zoo abrasion kuj, hnyav kuj thiab resilience.Lub hardness yog 60 ~ 80 shaw.Lub vijtsam nro, nto flatness ntawm substrate, koj yuav tsum xaiv lub siab hardness scraper.Ntawm qhov tsis sib xws, yuav tsum xaiv tsawg hardness.Nyob rau hauv qhov chaw nkhaus, qhov qis qis ntawm lub ntsej muag kheej kheej lossis lub tiaj tus (loj convex) substrate luam ntawv, scraper dav yuav tsum nqaim dua li qhov dav.
4. Kev tshuaj ntsuam luam ntawv
Siab khawb siab, tus number case, tab sis lub vijtsam yog yooj yim rau deformation, yog li qhov khawb siab yuav tsum tsis txhob siab.Scraping ceev feem ntau yog 60 ~ 200mm / s.Kev khawb nrawm, tsawg tus number case, tab sis tsis yooj yim los thaiv lub vas.Yog li ntawd yooj yim los thaiv tus number case, scraping ceev yuav tsum ceev.Scraping kab rau ncaj, oblique thiab nkhaus peb.Yuav tsum ua raws li lub substrate flatness thiab cov ntawv nyeem ntawm lub substrate faib los xaiv.Scraping kab ntev thiab number case noj, scraping number case yuav tsum ntau dua txawm scraping ib txheej ntawm number case, tom qab scraping.
5, ink npaj
Cov txheej txheem ntawm kev txiav txim siab concentration: degree ntawm concentration rau number case los ntawm kev tshuaj ntsuam, lub tshuab luam ntawv nto tsis tshwm screen lossis hlau kos duab.Nyias degree los tso rau ntawm qhov screen, number case nrog nws tus kheej qhov hnyav tuaj yeem ncav cuag los ntawm mesh tab sis tsis poob qhov zoo tshaj plaws.Thaum luam cov kab nyias, lawv yuav tsum tau thinned, txwv tsis pub, lawv yuav tsum tau thickened.
Cov saum toj no yuav ua li cas kom ntseeg tau qhov zoo ntawm kev tshuaj ntsuam luam ntawv zoo ntawm kev taw qhia ntawm no, kev tshuaj ntsuam luam ntawv zoo nrog rau kev npaj number case, kev xaiv tshuaj ntsuam, xaiv scraper, tshuaj ntsuam qhov chaw, txheej txheem luam ntawv.
