1.Yuav ua li cas huab cua -resistant polyester?
Huab cua Resistance Rating: ★★★☆☆ (Medium)
Nta: Qhov no yog qhov feem ntau siv thiab raug nqi - kev xaiv zoo. Nws muaj zoo elasticity thiab adhesion.
Lifespan: Pom pom chalking thiab fading feem ntau pib tshwm tom qab li 5-10 xyoo.
Daim ntawv thov tsim nyog: ru tsev thiab phab ntsa vaj huam sib luag rau cov nroj tsuag, warehouses, thiab lwm yam vaj tse uas colourfastness tsis yog ib qho kev txhawj xeeb tseem ceeb.
2.Yuav ua li cas yog huab cua tsis kam ntawm silicon- hloov polyester?
Huab cua Resistance Rating: ★★★★☆ (Zoo)
Nta: Qhia cov silanes rau hauv polyester resin ho txhim kho huab cua tsis kam, gloss retention, thiab anti-chalking zog piv rau cov qauv polyester.
Lub neej ua haujlwm: Txog li 10-15 xyoo.
Daim ntaub ntawv: Haum rau pej xeem thiab cov tsev lag luam uas xav tau huab cua tiv thaiv; ib qho kev xaiv sib npaug ntawm polyester thiab PVDF.
3.Yuav ua li cas cov huab cua resistant siab -hlau polyesters/super polyesters?
Huab cua Resistance Rating: ★★★★☆ (Zoo rau Zoo heev)
Nta: Los ntawm kev tsim cov resin tshwj xeeb thiab cov xim pleev xim, nws cov huab cua tsis kam mus los yog nce mus txog qib ntawm qee qhov PVDF, tab sis ntawm tus nqi sib tw ntau dua. Nws sawv cev rau txoj kev loj hlob tseem ceeb hauv xyoo tas los no.
Kev Pabcuam Lub Neej: Txog li 15 xyoos lossis ntau dua.
Cov xwm txheej siv tau: Siv tau dav, ib qho kev xaiv rau nruab nrab - mus rau - siab - lub tsev kawg.
4.Yuav ua li cas huab cua resistant PVDF (polyvinylidene fluoride)?
Huab cua Resistance Rating: ★★★★★ (Zoo heev)
Nta: Qhov no tau lees paub tias yog ib qho ntawm cov huab cua zoo tshaj plaws - tiv taus topcoats. Nws cov ntawv cog lus tshuaj muaj zog heev, tiv thaiv UV degradation, thiab nws muaj kev tiv thaiv zoo heev -chalking, xim tuav, thiab nws tus kheej- ntxuav cov khoom.
Lifespan: Feem ntau 20-25 xyoo lossis ntev dua.
Daim ntawv thov tsim nyog: thaj chaw thaj chaw, chaw ntau pob, tshav dav hlau, siab -cov tsev pej xeem kawg, thiab lwm cov haujlwm uas yuav tsum tau nruj me ntsis rau cov xim thiab lub neej ntev.
5.Dab tsi yog lwm yam tseem ceeb cuam tshuam?
Txheej Thickness
Lub hauv paus ntsiab lus: Lub thicker lub txheej, lub sij hawm tiv thaiv ntev dua.
Feem ntau, lub thickness ntawm topcoat yog ib qho tseem ceeb qhia txog huab cua tsis kam. PVDF coatings feem ntau xav tau cov coated topcoat (feem ntau tsis tsawg dua 20μm), thaum cov txheej txheem polyester zoo ib yam yog nyias.
Substrate Hom thiab Txheej
Lub substrate (xws li galvanized steel ntawv los yog aluminized zinc steel ntawv) thiab nws txheej hnyav txiav txim siab corrosion kuj ntawm pre-coated steel kauj. Yog hais tias lub substrate muaj tsis zoo corrosion kuj, nws yuav sai sai corrode los ntawm sab hauv thaum lub topcoat puas. Aluminized zinc steel ntawv (xws li 55% aluminium zinc) feem ntau muaj kev tiv thaiv zoo rau ntug corrosion dua li cov ntawv zoo tib yam galvanized steel.
Kev thov ib puag ncig
Ib puag ncig ib puag ncig: Cov nroog hauv av uas muaj huab cua tsis zoo.
Ib puag ncig hnyav: ntug hiav txwv dej (siab salinity, high humidity), thaj chaw muaj kev lag luam (acid rain, chemical pollution), high UV radiation area (high altitudes, tropical regions). Nyob rau hauv cov cheeb tsam hnyav no, lub tsho tiv no nrog cov huab cua tiv thaiv siab dua (xws li PVDF) yuav tsum raug xaiv.
