Selective list of decorative wall panel materials for buildings
Number | project | Water-based Porcelain Aluminum Veneer (interior and exterior walls) | Enamel Steel Sheet (Interior Wall Panel) | Fluorocarbon aluminum veneer (internal and external walls) |
1 | Environmental Health | New Waterborne Inorganic Paint, Industrial Policy Key Encouraged Products, Very low VOC emissions | Traditional high energy consumption products | High pollution, high environmental risk products named by the national environmental protection |
2 | Base Material | Aluminum (2~5mm) | Steel | Aluminum (2~5mm) |
3 | Substrate Density | 2710kg/m3 | 7850kg/m3 | 2710kg/m3 |
4 | Cure Temperature | 180-250℃， Low Power | Above 850℃, High Power | 180-250℃, Low Power |
5 | Hardness | 6H-9H | 9H | H-2H |
6 | Salt spray resistance | When the coating is damaged, there is still an anti-corrosion layer to protect the substrate, which is not easy to corrode. | The enamel layer is easy to collapse and fall off after being impacted, exposing the substrate and easy to corrode. | General |
7 | Wearability | Excellent | Excellent | best |
8 | temperature resistance | >600℃ | >450℃ | <260℃ |
9 | Weather Resistant | Excellent weatherability | good weather resistance | good weather resistance |
10 | Heat and Cold Shock Resistant | better | Poor | better |
11 | Scratch Resistance | No Scratches - Minor Scratches | No Scratches - Minor Scratches | Severe scratches |
12 | Shock resistance | Coating particle size micro-nano, It will not easily fall off after being impacted. | The enamel layer is thick, and the porcelain is easy to fall off, Exposed substrate | The coating has good impact resistance, Unbreakable |
13 | Fire Rating | A1 class non-combustible | A1 class non-combustible | A2 flammable |
14 | Fire performance | non-flammable, smoke-free, non-toxic, not afraid of cigarette butts | Non-flammable, smoke-free, and non-toxic | Temperature resistance, high temperature softening, Easy to decompose and produce harmful smoke |
15 | High temperature toxicity | inorganic coating, High temperature without any toxic gas release | inorganic coating, High temperature without any toxic gas release | Organic Coating, Release toxic gases at high temperature |
16 | Self-cleaning | Easy to clean, easy to erase with markers, good anti-graffiti and anti-paste performance | General | Easy Hanging |
17 | Accelerated Aging (QUV) | 5000 hours color difference≤5.0 | 4000 hours color difference≤5.0 | 4000 hours color difference≤5.0 |
18 | Glossy | matte, glossy | Highlight | matte |
19 | Colors | Colorful | Can only use high temperature paint, color is limited | colors limited |
20 | Painting | Sandblasted | High requirements on the substrate, generally use high carbon cast iron, because the substrate is cured at high temperature The thermal expansion and contraction are large, and the yield rate is low | Pre-treatment chrome, three coats and two bakes, more complicated |
21 | Construction | One coat and one bake or two coats and one bake, Convenient construction | Three painting and two baking, complex | Three coats and one bake, the construction is more complicated |
22 | Installation | The board itself is lighter, Dry hanging installation is simple and convenient | The board itself is bulky, Transportation and installation are difficult | The board itself is lighter, Dry hanging installation is simple and convenient |
Note: In view of the current national environmental protection policy, water-based porcelain aluminum plate has become an industry application trend. The actual effect can refer to the sample, and please refer to the appendix for related technical parameters. | ||||
