1.Dab tsi yog qhov txawv ntawm gloss ntawm galvanized pre-coated steel coils? Cov qauv ntsuas yog dab tsi?
Qib gloss ntawm galvanized ua ntej-coated steel coils feem ntau yog cais raws li tus nqi gloss specular (unit: GU) ntsuas ntawm 60℃geometric kaum sab xis. Feem ntau nws tuaj yeem muab faib ua pawg hauv qab no:
High Gloss: Gloss theem feem ntau> 70 GU. Qhov saum npoo yog ci li daim iav, nrog rau qhov pom kev muaj zog.
Semi-Gloss/Matte: Gloss theem feem ntau yog nyob nruab nrab ntawm 30-70 GU. Qhov no yog qhov gloss ntau tshaj plaws.
Tsawg Gloss: Gloss theem feem ntau <30 GU. Qhov saum npoo muaj qhov cuam tshuam tsis muaj zog thiab kev ntxhib los mos.
2.Yuav ua li cas xaiv qhov tsim nyog Gloss Level raws li daim ntawv thov scenarios?
Qhov kev xaiv ntawm gloss theem feem ntau yog nyob ntawm kev siv tshwj xeeb ntawm cov khoom, thiab muaj qhov sib txawv tseem ceeb hauv ntau qhov chaw.
Architectural Field (Roofing, Phab ntsa): Feem ntau, nruab nrab mus rau qis gloss theem (30-40 GU) raug xaiv.
Yog vim li cas 1: Kom tsis txhob muaj kuab paug lub teeb. High-gloss ntos pom lub hnub ci zog, uas yuav ua rau lub teeb paug rau ib puag ncig.
Yog vim li cas 2: Kev nyab xeeb ntawm kev tsim kho. High-gloss nto muaj qhov coefficient qis dua ntawm kev sib txhuam, ua rau lawv yooj yim rau plam thaum tsim kho ntawm lub ru tsev thiab lwm qhov chaw, ua rau muaj kev phom sij.
Yog vim li cas 3: Stain resistance thiab txij nkawm. Txheej aging thawj manifests li poob ntawm gloss. Nruab nrab mus rau qis gloss panels qhia tsawg qhov sib txawv ntawm cov qub thiab tshiab thaum lawv muaj hnub nyoog, thiab xim txawv ntawm cov qub thiab tshiab panels tsis tshua pom thaum lub sij hawm tu.
3.Vim li cas qhov kev lag luam architectural nyiam nruab nrab rau qis gloss tiav?
Dhau li ntawm lub teeb muaj kuab paug thiab kev txhawj xeeb txog kev nyab xeeb uas tau hais tseg hauv Q&A dhau los, muaj kev xav tob dua tom qab xaiv qhov nruab nrab mus rau qhov tsis zoo:
Kev zais qhov tsis zoo me me: High-gloss nto ua zoo li iav, ua kom pom txawm tias qhov me tshaj plaws khawb, puas, lossis qhov tsis sib xws, ua rau lawv pom zoo heev. Qhov nruab nrab mus rau qhov tsis tshua muaj gloss zoo txo cov qhov tsis zoo, ua rau pom kev zoo nkauj zoo nkauj dua.
Cov nqi kho mob: siab- cov vaj huam sib luag gloss yog feem ntau ua rau pom cov plua plav, dej stains, thiab lwm yam av hauv kev siv txhua hnub, uas yuav ua rau muaj kev tu ntau zaus thiab kim dua.
4.Dab tsi yog kev sib raug zoo ntawm gloss, txheej txheej, thiab durability?
Hom txheej ncaj qha cuam tshuam rau nws lub peev xwm los tswj gloss. Txawv topcoats sib txawv heev nyob rau hauv huab cua tsis kam thiab gloss retention:
Polyester txheej (PE): Tus nqi qis, nrog zoo hardness thiab saj zawg zog, nws yog cov txheej txheem dav siv. Txawm li cas los xij, nws qhov kev tiv thaiv UV thiab gloss retention yog qhov nruab nrab, ua rau nws tsim nyog rau kev siv sab hauv tsev lossis thaj chaw uas muaj huab cua zoo.
Silicone-hloov polyester txheej (SMP): Hloov nrog silicone, nws cov kav ntev, gloss retention, thiab xim tuav tau zoo dua li polyester zoo tib yam.
High-durability polyester txheej (HDP): Muab qhov zoo ntawm polyester nrog superior durability, muab tus nqi siab -kev ua tau zoo piv.
Fluorocarbon txheej (PVDF): Muab qhov zoo tshaj plaws durability thiab zoo heev gloss thiab xim tuav, tab sis yog kim thiab muaj kev xaiv xim. Nyob rau hauv cov cheeb tsam uas muaj zog UV hluav taws xob, hom no ntawm siab- txheej txheej yuav tsum yog qhov kev xaiv.
5.Yuav ua li cas ntsuas thiab ntsuas gloss?
Ua raws li cov qauv ntsuas ntsuas yog qhov tseem ceeb rau kev ua kom cov khoom zoo thiab kev sib koom ua ke. Raws li GB / T 13448-2019, cov txheej txheem yog raws li hauv qab no:
Instrument Preparation: Use a standard 60° gloss meter. For surfaces with extremely high gloss (>70 GU) los yog tsis tshua muaj gloss (<30 GU), a 20° or 85° measurement angle may be necessary for more accurate results.
Kev Npaj Ua Qauv: Xyuas kom cov qauv ntsuas yog tiaj tus, tsis muaj roj thiab puas, thiab tsis pub tsawg dua 71mm × 110mm.
Environmental Requirements: Kev ntsuas yuav tsum tau ua nyob rau hauv chav tsev kub. Thaum muaj kev tsis sib haum xeeb, tus qauv yuav tsum muab tso rau hauv ib puag ncig ntawm 23℃± 2℃thiab 50% ± 5% txheeb ze av noo rau 24 teev ua ntej ntsuas.
Calibration thiab Measurement: Lub gloss meter yuav tsum tau calibrated siv tus qauv phaj ua ntej ntsuas. Tso lub gloss meter mus rau qhov sib npaug ntawm qhov kev taw qhia dov ntawm cov ntaub ntawv thiab ua qhov ntsuas tsawg kawg peb qhov chaw sib txawv ntawm qhov chaw.
