The first type, pure cork flooring, thickness is 4~5 mm. If you only take a small piece, it is like a moisture-proof pad. It is very rough and original from the color of the flower. There is no fixed pattern. It is familiar with us. The stripe floor is very different, although there are dozens of colors, but the difference is not very obvious; its biggest feature is pure cork, pure texture, very environmentally friendly. Its installation method adopts the sticking type, that is, it is directly pasted on the ground with special glue, the construction process is more complicated, and the requirements on the ground are also higher. From the price point of view, this floor market price is more than 100 yuan / square meter, the price is relatively low.
The second type, cork flooring, has three layers from the section, the surface layer and the bottom layer are cork, and the middle layer is sandwiched with a medium density board with a tongue and groove (locking), the thickness can reach about 10 mm, commonly known as "sandwich". The two layers of cork inside and outside can achieve a very good mute effect, and the color is the same as that of pure cork flooring. However, it is much simpler from the point of view of installation. It is mainly suspended, that is, similar to the laminate floor, and the ground requirements are not too high. The price of this kind of cork flooring is relatively high, and the general market price is more than 300 yuan / square meter. Both of the above cork floorings come from the Amorin company in Portugal, which is pure and environmentally friendly.
The third type, cork mute floor, which is a combination of cork and composite floor, the bottom layer is cork, the surface is composite floor, and the middle layer is also sandwiched with a medium density board, which can reach 13.4 mm. When the person walks on it, the bottom layer of cork can absorb a part of the sound, which plays a role in lowering the sound, because there is enough thickness and the foot feels very good.
Due to the different types, the places used are different. For shops, corridors, and places where traffic is difficult to avoid sand, the second and third types of flooring should be used. The surface layer has a thick flexible wear layer. After the sand is pressed into the wear layer, the sand will not slide. When the foot leaves, the sand will be ejected without scratching the wear surface. This is its advantage; but the surface is non-toxic. PVC, pure PVC resin can not be used as wear-resistant protective layer, it is brittle and easy to age, so plasticizer, heat stabilizer, light stabilizer, anti-blocking agent, antistatic agent, etc. should be added to the formulation, although The floor formulation strictly requires that these additives be non-toxic, but at least the plasticizer is odorous, easily migrates to the surface of the PVC, and is easily leached by the solvent, and may accelerate the aging of the product, so it is not suitable for the bedroom. At the same time, the two types of glued cork layers have been over-compressed, so the functions of heat insulation, sound reduction, shock absorption and the like are deteriorated. At present, some domestic consumers admire foreign products, blindly choose high-priced foreign second- and third-class products, and have doubts about the anti-storage of cheap domestic first-class products. From a scientific point of view, the life of a typical PU coating is about 15 years. The coating should be renewed when the first coating has a life of more than 10 years. The aging life of PVC plastic is not as good as that of PU resin. After aging, there will be hydrochloric acid and chlorine. Ion contamination, therefore, the first type of floor should be preferred for the bedroom floor.

Anodizing treatment is a surface finishing process for aluminum that forms a protective oxide layer on the surface of the metal. The process involves immersing the aluminum material in an electrolytic solution and passing an electric current through it. This creates a uniform and durable oxide coating that enhances the corrosion resistance and aesthetic appeal of the metal.
There are two main types of anodizing treatment: sulfuric acid anodizing and hard anodizing. Sulfuric acid anodizing is the most common type and produces a thinner, more decorative layer of oxide coating, while hard anodizing results in a thicker, harder, and corrosion-resistant layer that is ideal for industrial and automotive applications.
Anodizing treatment provides numerous benefits to aluminum products. It increases their resistance to corrosion and wear and tear, making them suitable for use in harsh environmental conditions. The process also enhances the strength and durability of the metal, extending its lifespan and reducing the need for maintenance.
Another advantage of anodizing treatment is its ability to add color and texture to aluminum products. Different dyes can be added to the electrolyte solution to produce a range of colors, from bright and vibrant to more subdued tones. Additionally, different textures and finishes can be achieved through specialized anodizing processes, such as matte anodizing or brushed anodizing.
Anodizing treatment is commonly used in various industries, including aerospace, automotive, construction, and consumer goods. It is an eco-friendly process as it uses no hazardous materials and produces minimal waste. However, it is important to note that anodizing treatment may affect the dimensional accuracy of the product and may mask defects that are present on the surface of the material.
Overall, anodizing treatment provides an effective way to enhance the functionality and appearance of aluminum products. As research and innovation continue to advance, even more advanced and innovative applications of anodized aluminum are expected to emerge.
