Lub viscosity ntawm silicone screen tshuab luam ntawv muaj cov yam ntxwv hauv qab no:
Viscosity ntau
Lub viscosity ntawm Silicone Screen Printing number case feem ntau yog qhov siab, feem ntau ntawm 350MPAs · S thiab 100, {} MpaG · S (yuav txawv ntawm cov khoom mus rau cov khoom lag luam). Piv txwv li, qee qhov tsis tshua muaj kub uas muaj viscosity ntawm 350Mpa-high-{{7 000 mpa mpa. Cov viscosity siab pab rau hauv Ink tswj nws cov duab thaum lub sijhawm luam ntawv thiab zam kev khiav lossis pom.
Thixotropy
Silicone Ink tau pom tseeb thixotropy, uas yog, nws muaj lub viscosity siab thiab lub xeev jelly nyob rau hauv lub xeev zoo li qub; Thaum raug scraper siab, lub viscosity txo sai thiab ua tau yooj yim ntws, yog li nws tuaj yeem hloov tau yooj yim ntawm lub vijtsam mus rau substrate. Tom qab lub siab ploj, tus num yuav tuaj yeem rov qab sai rau lub xeev viscosity siab los xyuas kom meej thiab ruaj khov ntawm cov qauv luam tawm.
Viscosity kev hloov kho
Lub piscosity ntawm tus number cas tuaj yeem hloov kho los ntawm kev ua kom dhau (xws li kerosene, tsw yas lossis tshwj xeeb. Raws li cov kev cai ntawm cov txheej txheem luam ntawv thiab substrate, lub viscosity tuaj yeem hloov kho rau cov khoom tsim nyog los xyuas kom cov luam ntawv nyhuv.
Kev sib raug zoo ntawm viscosity thiab luam ntawv zoo
Viscosity yog dhau lawm:Tus number case yog qhov nyuaj kom dhau ntawm lub vijtsam, uas yuav ua rau cov qauv luam tawm tsis tiav lossis ploj lawm.
Viscosity yog tsawg dhau:Tus number case yog qhov yooj yim ntws thiab saib ntawm substrate, cuam tshuam rau kev luam ntawv raug thiab qhov tseeb ntawm cov qauv.
Viscosity stabilab
Silicone number case xav tau kom muaj viscosity stability thaum lub sij hawm luam ntawv los xyuas kom qhov sib xws ntawm luam ntawv zoo. Kev hloov pauv hauv viscosity yuav cuam tshuam rau kev hloov pauv kev ua tau thiab luam ntawv nyhuv ntawm number case.
Viscosity Ntsuas Ntsuas
Lub piscosity ntawm number cas feem ntau yog ntsuas siv vicometer, thiab ntsuas yuav tsum tau nqa tawm ntawm tus qauv kub (xws li 25 degree) kom zam dhau ntawm qhov kub ntawm viscosity.
