Lub elasticity thiab hardness kev ua tau zoo ntawm flexographic luam ntawv yog qhov tseem ceeb cuam tshuam rau kev luam ntawv zoo.
1. Elasticity kev ua tau zoo
Lub ntsiab lus ntawm elasticity: Elasticity yog ib qho tseem ceeb ntawm flexographic luam ntawv daim hlau, uas txiav txim siab lub peev xwm rov qab los ntawm daim hlau tom qab nias. Cov phaj nrog zoo elasticity tuaj yeem hloov kho kom zoo rau saum npoo ntawm lub substrate thaum lub sij hawm luam ntawv, yog li ua kom muaj kev sib hloov ntawm tus number case.
Kev sib raug zoo ntawm elasticity thiab substrate: Cov yam ntxwv saum npoo ntawm lub substrate muaj qhov sib txawv elasticity xav tau rau cov ntawv luam ntawv. Piv txwv li, substrates nrog du nto yuav tsum tau luam ntawv daim hlau nrog tsawg elasticity los xyuas kom meej qhov meej ntawm luam ntawv; thaum lub substrates nrog ntxhib nto yuav tsum tau luam daim hlau nrog ntau dua elasticity los xyuas kom meej txaus hloov ntawm tus number case.
Kev hloov hauv elasticity: Thaum lub sij hawm luam ntawv, lub elasticity ntawm lub phaj luam ntawv yuav hloov mus rau ib qho twg. Tshwj xeeb tshaj yog tom qab kev kub ceev thiab ntev -lub sij hawm luam ntawv tas mus li, lub elasticity ntawm cov ntawv luam ntawv yuav txo qis, uas ua rau tsis txaus rebound. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tswj lub teeb lub zog ntawm lub zog thaum luam ntawv kom txo tau qhov elasticity ntawm cov ntawv luam ntawv.
2. Hardness kev ua tau zoo
Lub ntsiab lus ntawm hardness: Hardness yog hais txog lub peev xwm ntawm cov ntawv luam ntawv los tiv thaiv sab nraud rau hauv nws qhov chaw. Qhov loj ntawm hardness ncaj qha cuam tshuam rau kev luam ntawv tsis kam thiab cov nyhuv luam tawm ntawm lub phaj luam ntawv.
Yam tseem ceeb cuam tshuam rau hardness: Lub hardness ntawm lub phaj luam ntawv yog cuam tshuam los ntawm ntau yam, xws li kub, siab, thiab nias lub sij hawm thaum muaj sulfur curing. Rau photosensitive resin daim hlau, lawv cov hardness kuj nyob ntawm qhov hardness ntawm photopolymer, uas tuaj yeem hloov kho los ntawm kev ntxiv tus neeg saib xyuas hardness.
Sib piv hardness nrog substrates: Cov substrates sib txawv muaj qhov sib txawv hardness xav tau rau cov ntawv luam ntawv. Piv txwv li, thaum luam ntawv khib nyiab lossis ntawv nyeem, lub phaj luam ntawv yuav tsum muaj zog dua los xyuas kom meej meej ntawm kev luam ntawv; thaum lub sij hawm luam ntawv dots los yog cov kab zoo, yuav tsum tau luam ntawv phaj nrog qis hardness los tiv thaiv dot expansion.
Hardness thiab luam ntawv nyhuv: Lub hardness ntawm cov ntawv luam ntawv tseem yuav cuam tshuam rau txheej txheej reproducibility thiab dot expansion ntawm cov khoom luam tawm. Lub phaj luam ntawv nrog siab hardness tsis yooj yim rau deform thaum lub sij hawm luam ntawv, uas tuaj yeem ua kom pom tseeb ntawm cov khoom luam tawm; thaum lub phaj luam ntawv uas tsis tshua muaj hardness yog qhov yooj yim rau dot expansion, cuam tshuam qhov zoo ntawm cov khoom luam tawm.
3. Kev sib raug zoo ntawm elasticity thiab hardness
Inverse Performance index kev sib raug zoo: Elasticity thiab hardness yog ob qho tseem ceeb ntawm kev ua tau zoo ntawm cov ntawv luam ntawv, thiab muaj qee qhov sib txawv ntawm qhov sib txawv ntawm lawv. Ntawd yog, qhov siab dua qhov hardness, qis dua elasticity; Qhov qis dua qhov hardness, ntau dua elasticity. Yog li ntawd, thaum xaiv lub tshuab luam ntawv, nws yog ib qho tsim nyog yuav tsum sib npaug ntawm ob qhov kev ua tau zoo raws li cov kev xav tau luam ntawv tshwj xeeb.
