Ink emulsification yog qhov hnyav
Nrog UV offset number case rau txhuas ntawv ci ntawv luam ntawv, luam ntawv, qee zaum pom tias lub tshuab luam ntawv nyob ib ncig ntawm cov plaub hau me ntsis, duab nraaj tsis meej, qhov no feem ntau yog vim tus cwj mem tsis txaus ua rau. UV number case thiab roj-based number case piv rau tus number case, number case thoob uv offset number case mov yog qeeb qeeb, thaum luam ntawv txheej number case yog thinner, uas ua rau ntau tus emulsification ntawm tus number case, emulsified number case yuav zwm hauv number case chais thiab cov seem ntawm txheej thiab roj hmab. daim ntaub, uas ua rau tsis meej duab.
Qhov kev kub siab ntawm cov kua thiab qhov kub thiab txias yuav tseem muaj kev cuam tshuam ntau dua rau kua mem emulsification. Txo cov tshuab luam ntawv ceev, tswj kev luam ntawv ceev ntawm 5000-8000 luam ntawv / teev, thiab rov kho dua qhov ntsuas cov kua txhaum thiab kev tshem tawm, qhov tshuaj lom ntawm isopropanol tswj ntawm 11-13%, kev coj ua ntawm 1800-1900uS / cm, pH tus nqi ntawm 5.6 -6, ntsuas kub ntawm 5-10 degrees C, tuaj yeem tswj tau zoo dua UV offset printing number case emulsification.
Tee number case thiab rub cov kua muag tshwm sim
UV offset number case txawm hais tias nws tus kheej viscosity, lub zog tsis zoo, tab sis nyob rau hauv chav tsev kub lossis huab cua tsis tshua zoo, tom qab lub sijhawm ntev ntawm kev ua haujlwm siab ntawm luam ntawv xovxwm, number case viscosity yuav raug txo ntau, ua kom zoo dua, yooj yim rau tsim cov nplauv ya tawm, qhov tshwm sim ntawm tee.
Thaum tus number case emulsification hnyav dhau lawm, UV offset number case nyob rau hauv dej yuav cuam tshuam rau uv hluav taws xob dhau tus nqi hluav taws xob dhau, yog li txo lub zog ntawm kev sib txuas, qee zaum txawm hais tias tus number case kho, tab sis tseem nyob hauv qhov ua yeeb yaj kiab cov yeeb yaj kiab tseem muaj dej noo, ib zaug kev sib txhuam los yog nrog cov nplaum ntawm lub nplaum nplaum cov qauv, koj yuav pom tias tus number case txheej yog rub tawm, qhov tshwm sim ntawm rub tus number case.
Ink adhesion tsis txaus
Vim tias cov zaj duab xis, ntawv hluavtaws, ntawv hlau, yas thiab lwm yam yog cov permeability tsis zoo, tus number case adsorption tsis muaj zog, txawm tias tom qab UV tua, number case adhesion kuj tsis zoo heev, luam ntawv tsis zoo yog tsis siab. Txhawm rau txhawm rau txhim kho tus number case adhesion, cov khoom yog feem ntau surfaced.
Feem ntau yuav ua rau UV offset number case tuaj yeem nyob rau hauv cov txheej txheem no ntawm cov ntaub ntawv zoo dua, lub nplaim yuav tsum tau nyob rau hauv 40dyne lossis siab dua, ua ntej luam ntawv yuav tsum xyuas lub zog saum npoo ntawm lub substrate, thaum siv cov corona tawm, kom nkag siab txog kev kho corona kho lub sijhawm. , kev kho mob corona tom qab ib lub lis piam yuav cia li thim rov qab, xws li yuav tsum tau rov siv tshuaj los kho kev kho mob, txwv tsis pub nws yuav cuam tshuam rau kev kho kom qhuav thiab number case txheej txuas.
Ink curing kom qhuav tsis tiav
UV offset luam ntawv, qee zaum txhawm rau txhim kho xim saturation ntawm UV luam ntawv, luam ntawv siab yog qhov loj dua, number case txheej yog tuab dua, lub network nce siab ntxiv, nws yuav ua kom nyuaj nyuaj rau kev ua kua dej, kom ntseeg tau tias xim xim, tuaj yeem tsuas tswj tau luam ntawv luam ntawv siab dua.
Lub sijhawm no, tseem yuav tsum muaj kev txo qis kev luam ntawv ceev, luam ntawv nrawm thiab UV number case tua kom sib phim, qeeb qeeb, ultraviolet lub teeb kis lub sijhawm yog sijhawm ntev, yog li ntawd cov kua txau tau kho, qhov tseeb siv pom tias luam ceev tswj 6000 txog 7000 daim ntawv / thaum cov ntawv ua kom zoo dua. Hloov kho qhov kev ncua deb ntawm UV teeb thiab substrate, nce qhov kev siv zog ntawm lub teeb UV kis tau yooj yim, tuaj yeem ua kom ceev cov kua mem hluav;
