Wallpapers have been recognized and used by more and more people, but in fact most people have little knowledge of wallpapers. There are a lot of learning in wallpapers. This week, Fuk Lok professionals summarized the main points of wallpaper selection.
1. Be concerned about materials
There are many kinds of wallpapers on the market, but there are many materials. Among them, paper-based PVC wallpapers account for more than half, the cost of raw materials is relatively low, some imported PVC wallpapers are very expensive; high-end wallpapers usually use pure paper and non-woven materials.
2. Conduct environmental testing
The environmental protection level of the wallpaper depends on the material and material grade, printing process, etc. The scene can be burned by the sample (the wallpaper with high environmental protection level has no burning odor, no smoke, the ash is gray powder) and the smell (PVC wallpaper has obvious plastic) The taste, low grade wallpaper has a strong printing ink smell) to identify. The newly opened and no odor pulp wallpaper has the highest environmental rating.
3. Focus on color fastness
Bright and colorful wallpapers are beautiful, but don't forget to wipe them with a damp cloth to see if they are discolored, especially some wallpapers with bumpy textures.
4. Focus on supporting accessories
When selecting wallpapers, you should also understand the use of base film (for wall covering), rubber powder and glue. They will directly affect the construction quality and post-effect of wallpaper. A complete set of wallpaper construction including primer + glue + wallpaper, any link is not environmentally friendly will affect the final construction effect. The link that is not visible - primer and glue are more critical. The construction problem of many wallpapers is caused by glue. It is best to choose a brand with a complete system, such as the Fule Pavilion primer, glue and Fiona wallpaper under the Danish Fuk Lok Group. Fuk Lok 270 glue is suitable for pure paper wallpaper paste, Fuk Lok 377 glue is suitable for non-woven wallpaper paste. Fulege wallpaper adhesive is environmentally friendly and tasteless. It is not easy to shrink, curl, and not easy to yellow. After the glue is dry, it becomes transparent. Therefore, the wallpaper glue is the best companion for eco-friendly wallpaper.
The hardness and density of tungsten are applied in obtaining heavy metal alloys. A good example is high speed steel, which can contain as much as 18% tungsten. Tungsten's high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris submarine-launched ballistic missile. Tungsten alloys are used in a wide range of different applications, including the aerospace and automotive industries and radiation shielding.Superalloys containing tungsten, such as Hastelloy and Stellite, are used in turbine blades and wear-resistant parts and coatings. Quenched (martensitic) tungsten steel (approx. 5.5% to 7.0% W with 0.5% to 0.7% C) was used for making hard permanent magnets, due to its high remanence and coercivity, as noted by John Hopkinson (1849 - 1898) as early as 1886. The magnetic properties of a metal or an alloy are very sensitive to microstructure.
