What em i Steel i gat Matt Kala.
MattSteel we i gat kala i tokbaot steel koil o pepa we oli pentem finis, we i gat wan finis we i no gat tumas gloss, we i no gat tingting long saed blong hem long fes blong hem.
Bilong wanem em i nambawan tru?
Proses bilong Prodaksen
- Ol stiel i gat kala i gat kala na ol i gat kala kala i gat kala long en, ol i serim wankain besik prodaksen proses:
No koilim → Siming → Bagarapim → Kemikel Pretritmen → Praim Koting→ Praim Beking
→ Praim Koling → Top Koting → Top Beking → Top Kulim → Inspeksen → Sliting → Rikoiling.
Tasol bikpela samting i narapela long ol ain i gat kala i stap insait long en i stap insait long topkot (pinis kot) stej.
- Ol stiel we oli putum kala blong hem long en:Long taim bilong topkot proses, ol i save putim yunifom long yunifom long dispela sabstret ol i bin tritim pastaim na bihain ol i bin oraitim long rot bilong bekim bilong kamapim wanpela gutpela pen film.
- Ol stiel i gat kala bilong Matt antap:Blong kasem embos efek, ol spesel koting fomulasen mo/o ol proses blong aplikesen oli yusum oltaem long taem blong topkot stej.
- Spesel koting fomulasen:Maet i gat sam samting we i ademap se, long taem blong bekem mo mekem i kam oraet, i mekem se ples blong kot i gotru long maekro-shrinkage o i no ron, mo long wei ia, i mekem se paten efek ia i embos (1}}
- Spesel koting proses:Dispela i ken involvim long kontrolim tiknes bilong koting, disainim rola bilong koting wantaim ol spesel samting, o kontrolim stret ol beking kondisen (olsem tempereja na eaflo) long kirapim koting long kamapim grid straksa ol i laikim long taim bilong oraitim. Sampela peten i kolim kontroling grid paten long rot bilong lukluk long wetpela piksa tiknes na koting konsumsen i save yusim .
Yu laik save tu long leit straksa na ol samting bilong en?
1. Jeneral Straksa bilong Koting Sistem (Long Insait i go long Ol Ausait Leia)
Tipikol koting straksa bilong ol stiel pepa i gat kala i gat ol dispela leit:
-
SUBSTRAT:
Dispela em i no kot yet, tasol em i wok olsem as bilong koting long bihainim.
Ol samting: Olpela steinles stiel, ol stiel pepa (GI/HDG - Hot-Dip Galvanis), ol galvanais aluminium-zinc stiel (GL/Galvalum/Aluzinc stiel i gat galvanis na aluminium-kotet stiel i stap long en (Stel bilong Aluminisaes), na ol narapela samting ol komon sabstret, olsem ol i save givim gutpela korosen proteksen.
-
PRE-TRITEMENT LAIER (PR-TRIMEN LAYER / SEMIKAL KONVESIN KONVESIN COATING)
I stap namel long metal sabstret na praim.
Wok:Ol strongpela samting i pas namel long koting na sabstret na i mekim gut moa yet strong bilong sabstret long daunim mak bilong en i pas wantaim.
Ol samting:Ol kain kain i save kamap em kromat tritmen na ol tritmen i no gat krom (olsem tritmen bilong silan na titanium zirconium sol tritmen). Wantaim ol samting bilong lukautim envairomen i wok long go antap, krom-fri tritmen i wok long kamap bikpela pinis.
-
PRIMER COAT
Aplai antap long pri-tritmen leya.
Wok:Bikpela samting i strongim pas namel long topkot na pri-tritmen leit na i givim moa korosen proteksen. Em i wanpela bikpela hap bilong koting sistem, na em i mekim bikpela wok long korosen resistens na strong bilong kala-kot pepa.
Ol samting:
Epoxy Resin: Wanpela komon praim samting i gat gutpela adhesen na korosen resistens.
Polyurethane: I givim gutpela fleksibiliti na abrasen resistens.
Polyester: Ol i ken yusim tu olsem wanpela praim.
Tiknes:Tipikal i liklik, planti taim namel long 5-20 maikron (μm).
- TOP COAT/FAINIS COAT
I aplae ova long praem leja, hem i aotsaed leja blong pepa we i gat kala mo i stap stret long ekstenel envaeromen.
Wok:I givim kala, gloss, teksa, na praimeri weta resistens, korosen resistens, UV resistens, na wear resistens. Ol lukluk lukluk na planti pefomens mak bilong ol kala-kotet pepa i save kamap long topcoat.}
Material Klasifikasen (bipo ol i bin kategorisim long resin taip):
| TAIP | SAMTING | OL APLAIKESEN |
|---|---|---|
| Polyester (PE) | Kost-ifektiv, bikpela kala opsen, gutpela adhesen, na gutpela prosesing | Moa long komon topkot bilong ol stiel pepa i gat kala; ol i save yusim planti long wokim ol samting bilong haus, ol samting bilong haus, na ol narapela samting bilong ol samting bilong haus, na ol narapela samting. |
| Poliesta (SMP) we Silikon i senisim. | Strongpela strong, weta i no inap bagarap, glos i stap yet, na em i no inap tingim silikon resin . | Ol rup bilong wokim haus, ol wol, na ol narapela aplikesen i mas i gat bikpela strong moa . |
| Poliviniliden Fluoride (PVDF) | Eksepsenel weta, UV, kemikol resistens, longpela laipspan, self-klining, fad, na chalking resistens | Ol bilding we oli hae tumas, ol wol blong keten, ol eapot, ol pawa plent, ol klaemet we oli strong tumas, mo ol hae nid blong durabiliti . |
| Hae-Durabiliti Polista (HDP) | Impruvum weta resistens mo i save stap longtaem ova long standet PE; Kost i daunbilo long PVDF | Mid-long-hai-end aplikesen we i nidim moa gud durability bitim PE be kos we i daon bitim PVDF . |
| Poliuten (PU) | Gutpela abrasen resistens, strong, kemikel resistens, na gutpela gloss ritensen | Ol aplikesen we i nidim hae abrasen mo impak resistens, olsem ol doa panel mo ol doa blong garaj . |
| Akrilik | Ol kala we oli klia gud, ol hae glos, be weta we oli no strong tumas blong agensem poliester . | Ol samting bilong bilasim haus, ol samting bilong haus, na ol hap i gat bikpela laik long mekim ol samting i luk nais tasol ol ples i no gat planti hevi long en. |
| Plastisol | Tik kot, gutpela abrasen na kemikel resistans, teksa pes i posibol | Ol aplikesen we i nidim tik kot mo abbrasen resistens: ol silo blong green, ol paeplaen, sam ples blong ruf |
| Spesel Topkot | Spesel wok: klinim yu yet, insulesen bilong hat, antibakterial, anti-statik | I bin kasem taem yu ademap ol spesel samting blong mekem ol resin o yusum ol spesel proses . |
- Kot bilong baksait (Kot bilong Bek)
Aplai long baksait bilong stiel pepa, planti taim long narapela sait bilong sabstret.
Wok:I givim proteksen bilong korosen long baksait na stopim ol mak long baksait sait. Em i ken gat tu wanpela aesthetik wok (e{1}}g{2}}, waitpela baksait kot).
Meteriel:Tipikal poliesta, epoksi resin, o ol narapela isipela fomulasen, wantaim tiknes i save liklik moa long topkot, olsem 5-10 maikron.
Dispela em i Promisteel Tian-kala seris bilong PPGI na PPGL. Bilong kisim moa infomesen, bihainim na WhatsApp mi.
