1.Dab tsi yog txoj cai ntsuas ntawm gloss meter?
Lub gloss meter ua haujlwm los ntawm kev simulating tib neeg lub qhov muag pom ntawm lub teeb. Nws xa cov teeb pom kev ruaj khov ntawm ib lub kaum ntse ntse (feem ntau 20 degree, 60 degree, lossis 85 degree) mus rau qhov qauv saum npoo. Ib tug ua tau - nyob rau hauv receiver ces ntsuas tus npaum li cas ntawm lub teeb reflected rov qab ntawm tib lub tab sis opposite lub kaum sab xis. Qhov ntau dua qhov pom ntawm lub teeb, qhov siab dua qhov gloss.
2.Yuav ua li cas xaiv lub kaum sab xis ntsuas?
60 Degree Angle (Lub Hom Phiaj Dav Dav):
Haum rau feem ntau galvanized coil khoom.
Kev ntsuas ntau: 10 - 70 GU.
Yog tias qhov kev nyeem tau siv lub kaum sab xis 60℃siab dua 70 GU, hloov mus rau 20℃kaum sab xis; Yog tias nws qis dua 10 GU, hloov mus rau 85℃kaum sab xis.
20℃Lub kaum ntse ntse (High Gloss):
Haum rau galvanized coils nrog ci ntsa iab heev, daim iav-zoo li qhov chaw (xws li, cov khoom uas tau polished los yog muaj anti- ntiv tes tiav).
Xav paub ntau ntxiv rau cov kev hloov pauv hauv siab -gloss nto.
Kev ntsuas ntau: Tshaj 70 GU.
85℃Lub kaum ntse ntse (Low Gloss lossis Matte):
Haum rau galvanized coils nrog rougher, matte tiav (xws li, qee yam khoom uas tsis tau polished lossis muaj spangles loj).
Ntau dua rau cov kev hloov pauv hauv qhov qis -gloss nto.
Kev ntsuas ntau: Hauv qab 10 GU.
3.Dab tsi yog qhov tsos thiab glossiness ntawm cov paj zinc li niaj zaus zoo li qhov muag liab qab?
Cov tsos mob: Pom pom ntawm qhov muag liab qab, cov zinc flakes muaj qhov txawv, ci iab, snowflake - lossis hnub qub - cov qauv zoo li. Cov crystals kuj loj heev.
Gloss: Feem ntau siab vim hais tias cov zinc flake crystals muaj ib tug du nto uas qhia txog lub teeb zoo. Qhov no muab cov zinc flakes pom qhov txawv "ci" tsos.
4.Dab tsi yog qhov tsos thiab glossiness ntawm me me zinc paj?
Cov tsos mob: Cov txheej txheem tshwj xeeb (xws li dej pos huab thiab cov tshuaj tua hluav taws xob) txo qis kev loj hlob ntawm zinc spangles, uas ua rau muaj qhov sib xws, zoo nrog cov qauv siv lead ua tsis tshua pom.
Gloss:
Unpolished: Qhov saum npoo yog tawm -dawb nrog lub gloss, feem ntau yog matte lossis qis-gloss.
Plain-ua tiav: Qhov no yog qhov ua tiav tshaj plaws. Tom qab dhau los ntawm daim tawv nqaij- dhau lub zeb, qhov saum npoo yuav du thiab tiaj tus, nrog kev txhim kho gloss, tsim kom muaj kev sib xws, siab -gloss "daim iav" nyhuv. Qhov no yog qhov xav tau ua tiav rau ntau lub siab -kawg cov khoom siv hauv tsev thiab ua ntej-coated substrates.
5.Dab tsi yog lub hom phiaj ntawm kev ua tiav?
Txhim kho nto flatness thiab smoothness.
Tshem tawm yield plateaus, txhim kho processability.
Qhov tseem ceeb txhim kho gloss nto, ua kom nws zoo li ci ntsa iab thiab zoo ib yam.
