1.Yuav ua li cas txheej thickness cuam tshuam lub hnub tiv thaiv?
Muab cov txheej txheem yooj yim ntawm lub cev: Cov txheej tuab zoo dua thaiv cov txheej txheem kev laus xws li UV rays, noo noo, thiab oxygen los ntawm kev nkag mus ncaj qha mus rau hauv cov txheej txheem los yog substrate, yog li ua rau cov txheej txheem kev laus qeeb.
Khaws cov khoom xyaw zoo: Cov txheej txheem muaj ntau dua cov khoom xyaw zoo xws li tiv thaiv - cov xim pleev xim, UV absorbers, thiab stabilizers, thiab yuav siv sij hawm ntev dua, yog li txuas nws lub neej kev pab cuam.
Npog qhov tsis xws luag: Nws tuaj yeem npog qhov microscopic unevenness ntawm substrate nto, txo cov ntsiab lus tsis muaj zog hauv txheej thiab ua rau kev tiv thaiv zoo ib yam.
2.Vim li cas ho tsis thickness qhov kev txiav txim?
Cov nyhuv "tseem ceeb tuab": Txhim kho lub hnub tiv thaiv tsis yog linearly correlated nrog tuab. Thaum cov txheej txheej thickness nce mus txog "tus nqi tseem ceeb" txaus los npog qhov tsis xws luag thiab tsim ib qho kev cuam tshuam zoo (xws li, rau cov txheej txheem txheej txheej polyester, feem ntau siab dua 20-25 μm), kev nce ntxiv hauv cov tuab muaj qhov txo qis qis rau lub hnub tiv thaiv. Lub sijhawm no, lwm yam tseem ceeb dhau los ua lub raj mis.
Lub hauv paus tseem ceeb ntawm cov txheej txheem resin: Cov huab cua tsis kam ntawm txheej txheej yog nyob ntawm cov tshuaj lom neeg ruaj khov ntawm cov yeeb yaj kiab- ua cov resin.
Ordinary polyester (PE): Feem ntau cov huab cua tsis zoo; Txawm tias thaum siv thickly, nws qhia tau hais tias tsis zoo nyob rau hauv lub zog ultraviolet lub teeb. Nws kuj yog ib qho yooj yim rau chalking thiab poob ntawm gloss.
Silicone-hloov polyester (SMP) thiab siab- polyester durability (HDP): Lawv cov huab cua tsis kam yog qhov zoo dua li polyester zoo tib yam.
Fluorocarbon (PVDF): Fluorocarbon bonds muaj zog heev thiab zoo heev tiv thaiv UV degradation, ua rau nws xaiv sab saum toj rau huab cua tsis kam. Lub hnub tiv thaiv ntawm 20μm siab - zoo PVDF txheej deb tshaj li ntawm 50μm zoo tib yam polyester txheej.
Pigment zoo yog qhov tseem ceeb: High-kev ua tau zoo, hnub ci- cov xim tiv taus (xws li rutile titanium dioxide thiab siab-qib inorganic pigments) ua lub luag haujlwm tseem ceeb hauv kev khaws xim. Cov pigments tsis zoo yuav ploj mus sai heev txawm tias nyob hauv cov txheej tuab.
3.Dab tsi yog qhov cuam tshuam ntawm cov txheej txheej tuab heev?
Tus nqi nce ntxiv: Txheej yog ib qho tseem ceeb ntawm cov nqi, thiab cov thickness ntau dhau yog qhov tsis zoo.
Txo Flexibility: Lub thicker lub txheej, nws yooj yim dua rau tawg thaum khoov thiab sib sau ua ke (saib tshooj dhau los ntawm khoov teeb meem).
Adhesion Risks: Cov coatings tuab heev muaj kev ntxhov siab ntau dua, uas yuav cuam tshuam rau adhesion rau substrate.
4.Yuav ua li cas xaiv cov txheej txheej rau cov ntawv thov sib txawv?
Sab hauv / Ib puag ncig ib puag ncig: Polyester (PE)
Tsev Sab nrauv / ru tsev: HDP, SMP
Hnyav Environments/Beachfront, Industrial Areas: PVDF
5.Dab tsi yog qee cov lus qhia rau kev xaiv tus khub?
Ua ntej qhov tseem ceeb: Thaum xaiv xim -coated coils, ua ntej txiav txim siab txheej txheej txheej raws li huab cua tiv thaiv (xws li PVDF lossis HDP), tom qab ntawd xaiv qhov tuab tsim nyog nyob rau hauv qhov kev pom zoo.
Ua raws li "Zoo txaus" Txoj Cai: Tsis txhob ua qhov muag tsis pom qhov tuab. Rau feem ntau cov ntawv thov kev tsim vaj tsev, lub tsho sab saum toj tuab ntawm 20-25μm nrog siab- polyester kev ua tau zoo (HDP / SMP) lossis 20μm lossis ntau dua nrog PVDF sawv cev rau qhov zoo tshaj qhov sib npaug ntawm cov nqi-zoo thiab kev ua haujlwm.
Ua kom pom tseeb ntawm Kev Zoo Tag Nrho: Xyuas kom meej tias qhov sib txuam primer, substrate txheej, thiab kev kho saum npoo raws li cov qauv. Kev ua tiav, siab - txheej txheej txheej txheej zoo yog qhov tseem ceeb tshaj qhov tsuas yog ua kom lub thickness ntawm topcoat.
Thov Cov Ntaub Ntawv Kev Lag Luam los ntawm Cov Khoom Muag: Thov cov ntaub ntawv sib piv los ntawm kev ntsuas kev laus kom nrawm (piv txwv li, QUV) ntawm cov qauv sib txawv ntawm cov thicknesses siv tib lub cev. Qhov no yog txoj kev txheeb xyuas ncaj qha tshaj plaws.
