1.Yuav ua li cas zoo yog PVDF (polyvinylidene fluoride) txheej?
Kev piav qhia: Qhov no yog tam sim no qhov zoo tshaj plaws txheej txheej txheem ntawm UV tiv thaiv thiab huab cua tsis kam, tsis muaj dab tsi. Cov qauv molecular ntawm PVDF resin yog qhov ruaj khov heev, nrog cov khoom siv tshuaj lom neeg ntau dua li cov teeb ci ultraviolet, ua rau nws nyuaj rau UV rays ua rau nws cov qauv molecular puas.
Cov ntsiab lus tseem ceeb:
Gloss Retention: Feem ntau tshaj 20 xyoo, nrog siab - cov khoom zoo tshaj 30 xyoo.
Xim Retention: Zoo heev; resistant rau fading thiab discoloration.
Anti-Chalking: Zoo heev; txheej txheej yuav tsis chalk los yog tev tawm vim raug tshav ntuj ntev.
Txoj Cai Ua Haujlwm: PVDF txheej feem ntau siv ntau dua 70% PVDF resin ua ke nrog 30% siab- cov xim zoo (xws li cov xim tsis muaj organic ceramic), kho los ntawm siab - kub ci los ua ib qho kev tiv thaiv zoo heev.
Daim ntaub ntawv: Feem ntau yog siv rau hauv thaj chaw thaj chaw, tshav dav hlau, chaw ntau pob, thiab lwm yam kev siv uas yuav tsum tau ua kom muaj zog heev.
2.Yuav ua tau zoo npaum li cas yog HDP (cov huab cua siab -resistant polyester) txheej?
Kev Qhia Txog Kev Ua Haujlwm: Nws tuaj yeem suav tias yog qhov hloov kho dua tshiab ntawm polyester zoo tib yam (PE). Los ntawm kev siv huab cua ntau dua -cov resins tiv taus thiab cov pigments ruaj khov, nws cov UV tiv thaiv yog qhov zoo dua li polyester zoo ib yam, nce mus txog qib ntawm PVDF, tab sis tus nqi qis dua.
Cov ntsiab lus tseem ceeb:
Gloss Retention: Feem ntau 10-15 xyoo.
Xim Retention: Zoo heev.
Anti-Challing: Zoo.
Cov ntawv thov: Siv dav hauv high-cov tsev lag luam kawg, cov zej zog nyob, thiab lwm yam, ua rau nws muaj kev ua haujlwm siab -kev ua tau zoo, nqi- kev xaiv zoo.
3.Qhov PE (polyester) txheej zoo li cas?
Nqe lus piav qhia: Qhov no yog cov txheej txheem siv ntau tshaj plaws thiab kev lag luam. Nws qhov kev tiv thaiv UV ua tau raws li cov kev xav tau ntawm cov tsev lag luam feem ntau thiab cov kev siv dav dav, tab sis nws qhov kev ua tau zoo degrades ntau dua nyob rau hauv lub sij hawm raug tshav ntuj piv rau ob qho dhau los.
Cov ntsiab lus tseem ceeb:
Gloss Retention: Feem ntau 5-10 xyoo.
Xim Retention: Zoo, tab sis xim tsaus nti (xws li xiav tsaus thiab cib liab) yuav ploj zuj zus thaum lub sijhawm.
Chalking Resistance: Ncaj, tab sis me ntsis chalking yuav tshwm sim ntawm qhov chaw tom qab siv ntev.
Daim ntaub ntawv: Industrial nroj tsuag, logistics warehouses, thiab lwm yam.
4.SMP (silicone- hloov polyester) txheej zoo li cas?
Kev Qhia Txog Kev Ua Haujlwm: SMP feem ntau muaj kev tiv thaiv UV zoo dua li PE zoo tib yam, tab sis tej zaum yuav qis dua HDP me ntsis. Nws lub ntsiab zoo yog zoo heev hardness thiab abrasion kuj, thiab muaj zog stain kuj.
Daim ntaub ntawv: Haum rau cov ntawv thov uas yuav tsum tau muaj kev puas tsuaj siab thiab qee qhov kev tiv thaiv huab cua.
5.Yuav ntsuas thiab txiav txim siab UV tiv thaiv li cas?
Accelerated Aging Tests
Xenon Lamp Aging Test: Simulates full-spectrum sunlight and rain erosion. Results are typically expressed in hours; for example, >1000 hours indicates gloss retention >90%. PVDF txheej feem ntau tuaj yeem ncav cuag ntau txhiab teev.
QUV Ultraviolet Aging Test: Feem ntau simulates UV puas. Cov txiaj ntsig kuj tau qhia hauv cov xuab moos.
Nco tseg: Cov sij hawm xeem tsis tuaj yeem hloov pauv ncaj qha rau lub neej kev pabcuam tiag tiag, tab sis lawv tuaj yeem ua lub hauv paus tseem ceeb rau kev sib piv kev ua haujlwm ntawm cov khoom sib txawv. Cov sij hawm xeem siab dua qhia tau tias huab cua tsis zoo.
Lub Sijhawm Warranty
Lub luag haujlwm cov tuam txhab muab kev lees paub meej rau lawv cov khoom. Piv txwv li:
PE txheej: Tej zaum yuav muaj 5-10 xyoo warranty.
HDP txheej: Tej zaum yuav muaj 10-15 xyoo lav.
PVDF txheej: Tej zaum yuav muaj 20-25 xyoo lav lossis ntev dua.
Warranty coverage feem ntau suav nrog "tsis muaj chalking, tsis muaj tev, thiab tsis muaj xim txawv tshaj ΔE tus nqi".
Qhov cuam tshuam ntawm kev xaiv xim
Lub teeb xim (xws li, dawb, lub teeb grey): Xav txog feem ntau lub hnub ci thiab ultraviolet rays, nqus cua sov thiab lub teeb lub zog tsawg, yog li kev laus qeeb qeeb thiab muaj lub neej ntev dua.
Cov xim tsaus nti (xws li xiav tsaus, kas fes, ntsuab tsaus): nqus ntau lub teeb thiab cua sov, ua kom cov txheej txheej ntawm qhov kub siab dua rau lub sijhawm ntev, ua kom cov txheej txheem kev laus, ua rau pom kev fading thiab kev ua haujlwm tsis zoo. Rau qhov tsaus ntuj - cov xim xim, nws pom zoo kom xaiv cov qib siab dua - qib txheej (xws li PVDF).
