Cov txiaj ntsig ntawm UV number case yog dab tsi?

Kev loj hlob sai ntawm kev lag luam luam ntawv tsis yog tsuas yog xav tau qhov zoo thiab kev ua haujlwm zoo, txo nqi, tab sis kuj tsis tas yuav muaj kuab paug rau ib puag ncig. UV number case tuaj yeem luam tawm rau txhua lub substrate, thiab qhov zoo ntawm cov khoom luam tawm zoo dua li cov kuab tshuaj thiab cov dej gravure printing inks. Nws muaj cov txiaj ntsig xws li kev nthuav dav me me, lub teeb ci siab, tiv taus kev hnav thiab tshuaj lom neeg, tsis muaj kuab paug, cov nyhuv zoo ntawm kev tsim cov cim thiab lub zog npog, thiab tus nqi qis.

Ib, txhais ntawm UV number case
UV yog lub npe luv ntawm lo lus Askiv rau lub teeb ultraviolet, UV kho thiab qhuav kua mem, luv ua UV kua mem. UV kua mem yog qhov tseem ceeb yog kua mem uas tuaj yeem hloov pauv los ntawm lub xeev kua mus rau lub xeev khov nyob rau hauv qee qhov wavelength ntawm ultraviolet hluav taws xob.
Ob, Cov yam ntxwv ntawm UV number case
1. Kev ua haujlwm siab ntawm UV number case
Cov kua mem UV tsis muaj cov kuab tshuaj uas yaj thaum lub sijhawm luam ntawv, thiab cov khoom khov tseem nyob 100% ntawm lub substrate. Lub zog xim thiab cov qauv teev tseem tsis hloov pauv, thiab cov txheej tuab ntawm cov kua mem nyias heev tuaj yeem ua tiav cov txiaj ntsig luam ntawv zoo. Txawm hais tias cov kua mem UV kim dua li cov kua mem uas yaj, 1kg UV kua mem tuaj yeem luam tawm 70 square meters ntawm cov khoom luam tawm, thaum 1kg kua mem uas yaj tsuas tuaj yeem luam tawm 30 square meters ntawm cov khoom luam tawm.

2. UV number case tuaj yeem qhuav tam sim ntawd thiab muaj kev ua haujlwm siab
Cov kua mem UV tuaj yeem khov thiab qhuav sai sai hauv qab kev cuam tshuam ntawm lub teeb ultraviolet, thiab cov khoom luam tawm tuaj yeem muab sib dhos thiab ua tiav tam sim ntawd. Qhov ceev ntawm kev tsim khoom yog 120-140m / feeb, thiab nws kuj tseem tuaj yeem txuag tau 60% txog 80% ntawm thaj chaw khaws cia.
3. UV number case tsis ua rau ib puag ncig puas tsuaj
Cov kua UV tsis muaj cov kuab tshuaj uas yaj tau yooj yim, piv txwv li 100% tsis muaj kuab tshuaj, yog li cov kuab tshuaj organic tsis raug tso tawm mus rau hauv huab cua thaum lub sijhawm luam ntawv. Qhov no ua raws li cov cai ib puag ncig thiab tseem tshem tawm cov nqi rov qab siv cov kuab tshuaj.
4. UV number case muaj kev nyab xeeb thiab txhim khu kev qha
UV number case yog ib lub tshuab uas tsis tas yuav siv dej los yog cov organic solvents. Thaum cov number case khov lawm, cov zaj duab xis number case yuav muaj zog thiab tiv taus tshuaj lom neeg, tsis muaj kev puas tsuaj los yog tev tawm los ntawm kev sib cuag nrog tshuaj lom neeg. UV number case muaj kev nyab xeeb rau kev siv thiab tuaj yeem txuag cov nqi pov hwm rau cov neeg siv. Nws yog qhov tsim nyog rau kev ntim khoom thiab cov ntaub ntawv luam ntawv uas muaj kev xav tau kev huv huv xws li zaub mov, dej haus, thiab tshuaj.
5. Zoo heev UV number case luam ntawv zoo
Thaum lub sijhawm luam ntawv, UV number case tuaj yeem tswj tau cov xim sib xws thiab sib xws, cov txheej number case ntawm cov khoom luam tawm ruaj khov, qhov sib piv ntawm cov xim thiab cov ntaub ntawv txuas tseem tsis hloov pauv, qhov deformation ntawm cov dot me me, thiab nws qhuav tam sim ntawd, ua rau nws ua tiav ntau xim overprinting.

6. Cov kua mem UV muaj cov khoom ruaj khov. Cov kua mem UV tsuas yog khov kho hauv qab lub teeb UV, thiab lub sijhawm tsis qhuav hauv qab ntuj tsis muaj qhov kawg. Qhov yam ntxwv tsis qhuav no ua kom ntseeg tau tias cov kua mem viscosity tseem ruaj khov thaum lub sijhawm ua haujlwm ntev ntawm lub tshuab luam ntawv. Vim tsis muaj cov organic volatilization, tsis tas yuav saib xyuas cov kua mem viscosity kom ntseeg tau tias cov txheej txheem luam ntawv du thiab zoo luam ntawv ruaj khov. Yog li ntawd, cov kua mem tuaj yeem khaws cia ib hmos hauv lub thawv kua mem yam tsis muaj kev kho xim.
