UV Coatings Curing Principles los cuam tshuam UVLED Deep Light Curing

Lub hauv paus ntsiab lus ntawm solidification ntawm UV txheej: UV txheej yog tshwm sim los ntawm lub teeb los ntawm UVLED, tsim sculpting pawg los yog ions. Lub cev noob, cov noob monomer no pib cov tshuaj tiv thaiv los tsim cov khoom siv polymer, cov txheej txheem ua tiav tiav. Cia peb tham txog ntau yam uas cuam tshuam rau lawv txoj kev sib sib zog nqus. I. Qhov tob curing ntawm UVLED lub zog cuam tshuam ntawm ultraviolet hluav taws xob. Qhov teeb meem tseem ceeb yog tias cov molecular absorption ntawm lub teeb quantum nrog lub zog txaus los ua stimulating molecules, tawg mus rau hauv cov dawb radicals los yog ions, thiab tso cai rau saturated organic khoom rau aggregate, delegate, cross-linking thiab lwm yam tshuaj tiv thaiv, kom ua tiav lub hom phiaj ntawm solidification. Ntawm lawv, UVLED lub zog ntawm lub teeb tshwm sim los ntawm lub teeb tshwm sim los ntawm cov txheej txheem UV muab ntau tshaj lossis tsawg dua qhov cuam tshuam ntawm lub zog xav tau: 1. Kuv tsis paub tias UVLED txias lub teeb lub zog xav tau los ntawm lub teeb uas tshwm sim los ntawm lub teeb ua rau, xws li qhov muag tsis pom kev, tsis yog tsuas yog lub zog pov tseg xwb, tab sis kuj yog lub zog, tab sis kuj yuav ua rau muaj kev cuam tshuam ntau dhau, xws li raws li kev tawg sib sau ua ke, reflux cov tshuaj tiv thaiv, thiab lwm yam. 2. Thaum UVLED tsis txaus, nws tsis tuaj yeem ua kom tiav. Qhov thib ob, lub thickness ntawm UV txheej thickness cuam tshuam cov teebmeem ntawm UV txheej ntawm cov nyhuv ntawm ultraviolet curing. Cov txheej yog tuab heev, thiab lub sij hawm ziab yog ntev heev nyob rau hauv irradiation ntawm tib lub hwj chim lub teeb qhov chaw. Ntawm ib sab, nws cuam tshuam rau ziab ntawm UV txheej. Tsis tas li ntawd nyob rau hauv ib tes, qhov kub ntawm lub substrate yuav siab dhau heev lawm, uas ua rau deformation ntawm lub substrate; txheej txheej dhau lawm yuav ua rau cov khoom ntog gloss. Tsis tas li ntawd, cov xim, qhov kub thiab txias, curing ceev, thiab substrate nto ntawm UV txheej txheej yuav tsum tau npaj kom tsim nyog nyob rau hauv txawv tej yam kev mob xws li txawv tej yam kev mob xws li. Thib peb, cov nyhuv ntawm qhov curing nrug. UV teeb Nyob ntawm qhov sib txawv ntawm kev kho substrates, qhov dav dav dav yog li 10-15mm. Qhov kev ncua deb yuav tsum tau kho kom haum nrog lub zog radical ntawm substrate, txheej, thiab UVLED teeb. Plaub, qhov cuam tshuam ntawm UV optical curing ceev Nyob ntawm seb lub substrate, txheej txheej, txheej, curing nrug, thiab lwm yam, tsim nyog kho qhov curing ceev ntawm lub cuab yeej, qhov ruaj khov ceev ceev heev, UV xim ntawm lub substrate nto yog nplaum los yog qhov saum npoo tsis qhuav; Qhov saum npoo ntawm cov khoom yuav laus. Thib tsib, qhov cuam tshuam ntawm qhov chaw ua haujlwm. Thaum lub viscosity ntawm UV txheej hloov pauv heev vim qhov kub thiab txias, chav tsev kub yuav tsum tau hloov kho. Feem ntau, 15-25 C yog qhov tsim nyog dua, thiab nws tsis tas yuav tsum tau ncaj qha thaum khov.
