Aluminium embossed painting paints

There are two types of paints for aluminium embossed painting: PE and PVDF. Generally speaking, a PVDF color coated aluminum coil shows better performance than a PE coated one, especially in resistance to severe conditions.
These are sheets of aluminium embossed painting.
PE paint, also known as unsaturated polyester paint, is a compounded material containing a main agent, a promoter and an initiator. The three carry out a polymerization bridging reaction to cure. Compared with solvent-based wood paints, PE paint has the advantage of “100% reactivity”, which means that the liquid composition can be completely converted into a solid polymer without the release of by-products under the action of the initiator. The solvent paint needs a large amount of solvent to volatilize before it can form a paint film. In addition, the unsaturated polyester paint has good comprehensive performance, good sealing performance and high fullness. It is equivalent to PU paint in terms of wear resistance, heat resistance, corrosion resistance and high gloss but has better performances in fullness, transparency, filling and other aspects. Aluminium embossed painting by PE paint has excellent smoothness and hand feeling, used extensively as interior decoration and exterior advertising boards that display good resistance to common weather conditions like sunshine, wind, rain, frost and extreme temperatures.
PVDF paint mainly refers to a coating of a vinylidene fluoride homopolymer or a copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomer. The chemical structure of the fluoric acid base is so stable and strong that PVDF paint shows excellent mechanical properties such as abrasion resistance and impact resistance, and exhibits long-lasting fading resistance and UV resistance in harsh weather and environment. After PVDF paint is formed into a film, the molecular structure in the coating is tight and excellent in weather resistance. American research institutes have tested and compared fluorocarbon coatings and super-coatings and general coatings. In the year, it has been proved that the stability and durability of PVDF paint are 30 and 80% higher than those of the other two coatings. Aluminium embossedpainting by PE paint is used in a variety of harsh environments, especially for indoor, outdoor decoration, commercial use in public places.

Slitting of 1mm 2mm 4mm aluminium strip

图片
What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate ...

Diamond Embossed Aluminum Sheet Application

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid pu...

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking,...
