1.Yuav ua li cas hom thiab cov khoom ntawm txheej resin cuam tshuam qhov khawb kuj ntawm cov xim -coated panels?
Hardness thiab Abrasion Resistance: Qhov nyuaj rau kho cov yeeb yaj kiab, qhov zoo dua nws tiv thaiv khawb los ntawm cov khoom ntse. Piv txwv li:
Fluorocarbon resin (PVDF) thiab silicone-hloov polyester cob (SMP) muab siab hardness, ruaj khov molecular lug, thiab superior puas kuj tom qab kho, tshaj li zoo tib yam polyester resin (PE).
Ordinary polyester resin (xws li dav -lub hom phiaj PE) muaj qhov nruab nrab hardness, tab sis yuav tsis muaj khawb kuj yog siv rau hauv cov ntawv thov raug kev sib txhuam tsis tu ncua.
Cov ntaub mos mos (xws li qee cov acrylic resins) muaj qhov tawv tsis tshua muaj zog thiab, thaum yoog raws, muaj kev khawb tsis zoo thiab ua rau khawb.
Flexibility Balance: Siab hardness ib leeg tsis txaus; cov resin kuj xav tau qee qhov kev hloov pauv yooj yim. Yog hais tias cov zaj duab xis yog tawv heev thiab nkig, nws yuav "lov" (lub txheej peels tawm) thaum khawb. Kev hloov pauv nruab nrab tuaj yeem ua rau lub zog sab nraud los ntawm me ntsis deformation, txo qhov kev pheej hmoo ntawm khawb lossis tev. Piv txwv li, qee qhov hloov pauv polyester resins kho lawv cov qauv saw molecular kom ua tiav qhov sib npaug ntawm hardness thiab yooj, ua tiav ob qho tib si khawb thiab cuam tshuam.
2.Pigments thiab fillers nyob rau hauv lub txheej ua li cas cuam tshuam qhov khawb kuj ntawm cov xim -coated panels?
Hom, ntau npaum li cas, thiab dispersion ntawm pigments (rau xim) thiab muab tub lim (rau kev ua tau zoo) indirectly cuam tshuam khawb kuj los ntawm kev cuam tshuam cov txheej ntom thiab hardness:
Hard muab tub lim ntxiv: Qhov sib ntxiv ntawm siab -hardness inorganic fillers (xws li silica, alumina, thiab iav hlaws) rau ib txheej yog sib npaug rau ntxiv "hnav- cov khoom tiv thaiv" rau cov zaj duab xis resin, txhim kho cov txheej txheej hardness thiab hnav tsis kam. Piv txwv li, qee qhov kev lag luam, siab - khawb- tiv taus ua ntej- pleev xim rau cov vaj huam sib luag txhob txwm ua kom qhov feem pua ntawm silica muab tub lim los txhim kho khawb tsis kam.
Pigment/filler dispersion: Yog tias pigments lossis fillers tsis sib luag (agglomerate), qhov chaw "particle accumululation" tuaj yeem ua rau qhov tsis sib xws hauv cov txheej. Cov cheeb tsam agglomerated tej zaum yuav muaj cov qauv xoob thiab yooj yim poob thaum khawb, thaum cov cheeb tsam tsis muaj cov khoom yuav tsis muaj zog thiab muaj kev cuam tshuam ntau dua rau kev kos. Yog li ntawd, uniform dispersion yog ib qho yuav tsum tau ua ua ntej kom ruaj khov khawb tsis kam.
3.Yuav ua li cas txheej thickness thiab curing txheej txheem cuam tshuam qhov khawb kuj ntawm cov xim -coated panels?
Txheej thickness: Yog tias txheej txheej nyias dhau lawm, zaj duab xis "txheej txheej" tsis muaj zog, thiab txawm tias qhov khawb me ntsis tuaj yeem nkag mus rau txheej txheej (tshwj xeeb cov primer lossis substrate). Txawm li cas los xij, thicker tsis tas yuav zoo dua. Yog hais tias lub txheej yog tuab heev, tsis sib xws nyob rau hauv kev ntxhov siab thaum lub sij hawm kho yuav ua rau tawg los yog wrinkling, uas nyob rau hauv lem yuav txo tau khawb tsis kam (ua rau cov cheeb tsam tawg yooj yim mus khawb). Feem ntau, cov xim topcoat thickness ntawm cov xim -coated panels nyob ntawm 10-30μm (hloov nyob ntawm daim ntawv thov scenario), yuav tsum muaj qhov sib npaug ntawm "kev tiv thaiv txaus" thiab "tsim zaj duab xis ruaj khov."
Curing degree: Cov resin yuav tsum muaj siab -kub curing los ua tus ntoo khaub lig- cov qauv sib txuas (cov saw hlau molecular interconnected rau hauv lub network). Yog hais tias qhov kub thiab txias tsis txaus los yog lub sij hawm kho luv luv, cov resin yuav tsis tau hla tag nrho -txuas, ua rau tsis tshua muaj hardness thiab xoob qauv ntawm cov zaj duab xis, txo qhov khawb tsis kam ("mos khawb" los yog txheej txheej yuav tshwm sim thaum khawb). Yog hais tias lub txheej yog overcured, nws yuav ua nkig thiab nquag tawg thaum khawb kuj. Yog li ntawd, cov txheej txheem curing yuav tsum tau tswj kom meej (piv txwv li, qhov kub thiab txias profile ntawm lub qhov cub txuas ntxiv yuav tsum tau sib phim rau hom resin).
4.Yuav ua li cas cov txheej txheem kho deg cuam tshuam qhov khawb tsis kam ntawm cov xim-coated panels?
Coating surface modification: This involves creating a dense surface layer through specialized processes (eg, increasing the resin crosslink density) or introducing wear-resistant functional groups to enhance surface hardness.
Lamination: Qhov no suav nrog kev siv cov ntaub nyias nyias, hnav- cov yeeb yaj kiab tiv thaiv (piv txwv li, PET lossis PP) rau saum npoo ntawm cov xim - cov ntawv coated. Qhov no ua raws li "lub cev tiv thaiv txheej ntxiv." Thaum khawb, zaj duab xis absorbs lub zog, txo kev puas tsuaj rau txheej. (Cov kev kho no feem ntau yog siv rau cov xim -coated sheets siv nyob rau hauv high- khoom siv hauv tsev.)
5.Yuav ua li cas xaiv cov txheej txheej tsim nyog raws li cov xwm txheej sib txawv?
Rau kev siv sab nraum zoov nrog kev sib txhuam siab (xws li lub tsev kab hlau rhuav phab ntsa, laj kab sab nraum zoov, thiab cov thawv ntim): Kev khawb ntau heev - cov coatings resistant xws li fluorocarbon fiber (PVDF), silicone- hloov polyester (SMP), los yog cov txheej polyester reinforced nrog cov ntaub tawv tawv yog nyiam dua. Ib tug cwj mem hardness ntawm 2H los yog siab dua yog pom zoo.
Rau cov khoom siv hauv tsev / sab hauv tsev (xws li lub tsev tub yees thiab rooj tog vaj huam sib luag): Yog tias ob qho tib si zoo li thiab khawb kuj tseem ceeb, xav txog kev hloov pauv polyester txheej (xum hardness 1H-2H) los yog ua ntej- pleev xim rau cov xim uas muaj cov xim tsis muaj xim.
Rau cov ntawv thov kev sib txhuam qis (xws li cov khoom siv sab hauv zoo nkauj): Cov txheej txheem polyester txheej (xum tawv tawv HB-H) txaus; tsis tas yuav mus nrhiav kev khawb siab kom tsis txhob muaj nqi ntxiv.
