What is PU stone? High cost performance imitation stone facing

1、 PU stone component

The English name of PU is Polyurethane, referred to as PU, and the Chinese name is polyurethane. The full name is polyurethane. It is a polyurethane material made by addition polymerization of organic diisocyanate, or polyisocyanate and dihydroxy, or polyhydroxy compounds. It is a kind of polymer compound, which was produced by German scientist Bayer in 937.

It is known as the "fifth largest plastic" because of its superior performance. PU stone is a kind of wall decoration plate made of high-density polyurethane material after foaming in a special aluminum mold, and its surface is treated with anti-corrosion, wear-resistant, flame retardant, UV resistant and other functions.

The products made with it can imitate the natural surface of stone, but the weight is very light, only four kilograms per square meter.

2、 Type of PU stone

PU stone has its own rough and crazy natural fracture surface, which is finely made according to the true stone texture and special technology, with lifelike texture and rich texture layers.

All cultural stones have the shapes of PU stones, such as the Great Wall stone, tile board, running water stone, etc. in our traditional concept. In addition, there are more distinctive concrete water, mud board and mushroom stone.

1. The service life of PU stone is very long. The chemical structure of the polymer derived from PU polyurethane is very stable. It is not easy to react with chemicals in the air, cold and hot temperatures, etc., and then its properties change.

2. It is corrosion resistant, waterproof, and UV resistant. It can be used in any outdoor environment without deformation and bending due to weather changes. It does not fall off and has high durability.

3. Versatility, PU products, which can be nailed, sawed, planed, washed, and bent, without cracking, deformation, and moth eaten, can be used indoors and outdoors.

4. Good environmental protection, using synthetic fiber as raw material, reducing deforestation, reaching the national standard of non-toxic and harmless green products for engineering decoration.

5. It is light in weight, simple in construction, easy to handle without breaking, and has a very low loss rate. It can be installed by a single person.

6. Good fireproof performance. This product has passed the national fire detection and reached the B2 level standard. It can completely achieve the characteristics of non spontaneous combustion and non combustion supporting.

Treatment of base course - plastering the leveling course - arranging bricks, dividing grids, snapping lines - pasting mushroom stones - pointing - cleaning the surface.

1. Base course treatment: clean the impurities on the surface of the wall base course before construction to ensure that the wall surface is basically flat.

2. Plaster the leveling course: the leveling course is 1:3 cement mortar.

3. Brick laying, division and line snapping: the width of the brick joint is 8mm in principle, and the whole brick must be used for division and brick laying. If the whole brick cannot be used, the mortar joint shall be adjusted. If it cannot be adjusted, the whole brick shall be used for cutting.

4. Pasting light pottery stone: it shall be inlaid from bottom to top, and the bonding thickness shall be between 4 and 8mm.

5. Pointing: pointing shall be carried out first horizontally and then vertically according to the material and depth required by the design to ensure continuous, straight, smooth, crack free and hollowing free effect.

6. Clean the surface: when the surface is dry and the cement slurry is fast drying, wipe the whole surface with dry cotton yarn, and then rinse the paved light pottery stone with clean water.

The construction process of PU stone is very simple. It only needs to be made on the flat blank wall. Due to its portability and particularity, it can be cut randomly on site according to the design effect, which greatly saves labor and time costs.

With strong visual impact effect, simple and efficient construction technology and low installation cost, it has been widely used in airports, hotels, building materials, automobile factories, coal mines, cement plants, high-grade apartments, villas, landscaping, color stone art, parks and other places.

1. Indoor application

The PU stone skin is used to decorate the outside of the air conditioner, which has a high cost performance ratio. It matches with the wood veneer, making the background wall less boring. The texture of the wall art paint is more three-dimensional and simple, creating a sense of quiet space.

PU stone, as a facade material, is applied to the wall decoration of the living room. A slight sense of distance has more energy, which can make the whole space more eye-catching, magnificent and grand.

Bedroom background application

In terms of its function as a bedside parapet, PU stone shows not only outstanding expressiveness, but also inclusive creative transformation.

The deep and uneven decorative elements are combined with the light, and the vision is advanced and artistic, which makes the space have both the natural randomness and the style of a mansion.

2. Outdoor application

The concave and convex sections of PU stone can easily control the heavy space atmosphere, which is low-key and luxurious. The decorative surface with different texture and color gives people different feelings with casual natural design.

The interface is arranged with a fine grid, and the back is lined with waterproof PU stone with natural surface. Leave a gap between the grille and PU stone for polishing, and output simpler visual decoration and more aggressive tactile expression.

PU stone is a kind of imitation stone facing with high safety factor and high cost performance.

We all know that the comprehensive cost of original rubble is very high. PU stone applies the well-known materials to the decoration materials of real stones. Through technological progress, the pattern of natural stone is perfectly copied with rock slabs, so that more people can enjoy its beautiful texture and texture.
