Elasticity thiab hardness kev ua tau zoo ntawm flexographic luam ntawv
1. Lub hardness ntawm cov roj hmab phaj ntawm lub tshuab luam ntawv flexographic yog txiav txim siab los ntawm qhov kub, siab, thiab lub sij hawm nias thaum lub sij hawm sulfur curing. Lub hardness ntawm lub phaj tuaj yeem txiav txim siab raws li qhov yuav tsum tau ua. Lub hardness ntawm photosensitive resin phaj nyob ntawm qhov hardness ntawm photopolymer, uas tuaj yeem tswj tau los ntawm kev ntxiv tus neeg saib xyuas hardness. Elasticity yog qhov taw qhia rov qab ntawm hardness, uas yog, qhov siab dua qhov hardness, me dua elasticity.
2. Cov substrates sib txawv muaj cov kev xav tau sib txawv rau lub hardness ntawm lub phaj. Yog hais tias lub phaj muaj elasticity siab, kev sib cuag nrog lub substrate yog uniform, thiab cov luam ntawv number case xim kuj zoo ib yam, tab sis cov txheej reproducibility ntawm cov duab yog tsis zoo, thiab cov dot expansion yog qhov tseem ceeb. Yog hais tias qhov saum npoo ntawm lub substrate yog du, lub phaj elasticity yuav tsum me me; Yog hais tias qhov saum npoo yog ntxhib, lub phaj elasticity yuav tsum loj. Rau luam ntawv khib nyiab lossis ntawv, phaj elasticity yuav tsum loj; rau luam ntawv dots lossis kab zoo, lub phaj elasticity yuav tsum me me.
3. Lub elasticity ntawm flexographic luam ntawv phaj yuav hloov mus rau ib qho twg thaum lub sij hawm luam ntawv, uas yog, tom qab kev kub ceev thiab lub sij hawm ntev luam ntawv, lub elasticity ntawm cov ntawv luam ntawv yuav txo qis thiab cov rebound yuav tsis txaus. Txhawm rau kom tsis txhob muaj qhov txo qis hauv elasticity ntawm lub phaj luam ntawv, nws yuav tsum tau ua kom muaj lub teeb ci siab thaum luam ntawv.
