Cov nplaum ntawm PTP aluminium ntawv ci yog coated rau sab hauv ntawm cov ntawv ci txhuas, thiab nws txoj haujlwm yog ua kom cov ntawv ci txhuas thiab cov ntawv siv tshuaj PVC tawv tawv tawv kom sov-nias ua ke, kom cov tshuaj hauv cov ntawv yas tawv tawv yog sib cais. los ntawm lub ntiaj teb sab nraud, thiab ua tiav lub hom phiaj ntawm kev sib khi cov tshuaj. Nyob rau hauv tus txheej txheem ntawm kev thauj cov tshuaj rau tshav kub sealing, cov nplaum txheej yog qhib los ntawm thermal siab, yog li ntawd nws yog ruaj khov kho rau PVC yas tawv daim ntawv, uas yuav tsum tau cov nplaum txheej thiab PVC resin yuav tsum muaj zoo tshav kub rhiab heev thiab compatibility nrog lub substrate.
Thaum tus number case nrog loj viscosity yuav tsum tau diluted nrog ib tug loj npaum li cas ntawm thinner, nws yuav tsum tau stirred thaum ntxiv lub thinner, thiaj li hais tias lub thinner yog sib npaug zos rau tag nrho cov number case. Ntsuas los ntawm dosimeter, nws yog hais txog 20-30s. Nyob sab hauv tsev kub thiab av noo muaj peev xwm cuam tshuam rau tus number case concentration, nws yog qhov zoo tshaj plaws los siv tus number case concentration detector los txiav txim seb tus npaum li cas ntawm cov kuab tshuaj ntxiv, thiab raws li qhov kev hloov ntawm qhov kub thiab av noo, txhua lub sijhawm los txiav txim siab tus number case concentration.
Thaum siv intaglio luam ntawv los luam cov khoom lag luam aluminium ntawv ci, cov number case concentration tsawg dhau, nws yuav ua rau cov xim ntawm cov ntawv luam tawm cov qauv tsis ci, thiab cov qauv tshuaj ntsuam yuav tsim cov phenomenon ntawm paste phaj; tus number case concentration siab dhau lawm, nws yuav tsim qhov tshwm sim ntawm kev tawg ntawm txheej, uas tsis yog tsuas yog pov tseg ntawm tus number case, tab sis kuj ua rau cov luam ntawv nto tsis tiaj tus, thiab nws kuj tsis zoo nkauj. Tsis tas li ntawd, raws li kev ceev ntawm aluminium ntawv ci tshuab luam ntawv txheej tshuab thiab luam ntawv gravure roller inking qhov tob kom xaiv tus number case zoo tshaj plaws.
