First, classified by substrate material
1 paper base
Wood pulp paper made from high-quality thin-cut lumber (grass paper has poorer elasticity and toughness than wood pulp paper) is used as a base material, and then various materials are composited on the paper base. Due to the mature production process, many wallpaper manufacturers at home and abroad have adopted paper-based wallpaper substrates.
2 fiberglass based
Glass fiber is an inorganic non-metallic material with excellent properties. The main raw material for the production of glass fiber is quartz sand, and the production process can be roughly divided into two categories: one is to directly make molten glass into fiber; the other is to make molten glass into a glass ball or rod with a diameter of 20mm, and then use a variety of methods. After heating and remelting, ultrafine fibers with a diameter of 3 to 80 μm are produced. The main features of this type of wallpaper are anti-corrosion, moisture-proof, heat-insulating, sound-absorbing, flame-retardant, shock-absorbing, and high physical strength. However, glass fiber can cause irritation to the skin and respiratory tract. At present, only a few manufacturers still use this material.
3 non-woven base
This kind of wallpaper is based on non-woven fabrics (also called non-woven fabrics). Non-woven fabric is a type of non-woven fabric, which is directly formed into a mesh or sheet structure by short fibers or filaments through air flow or mechanical forming, and then processed through different processes such as hydro-entangling, needle punching and hot rolling. .
There are many kinds of fiber raw materials suitable for non-woven fabrics, mainly natural fibers and chemical fibers. In order to produce nonwoven fabrics of different properties, uses and styles, high-performance specialty fibers and functionalized, differentiated fibers can also be used. The advantages of non-woven substrates are good toughness, breathability, waterproofness, and environmental protection, and they require less wall surface when installed.
In the non-woven material, the velvet fibers processed by the wet process of the long fiber yarn have better mechanical strength, flexibility, and deformation resistance, so the velveteen fiber wallpaper has better physical strength and space stability. . If velvet fiber is used as the surface layer of wallpaper, it will show stronger silky texture.
This type of wallpaper uses a textile cloth as a base material. The production process is generally made of cotton fibers or synthetic fibers made of latitude and longitude lines, and then sprayed on the surface of PVC paste resin or paste the PVC surface layer, and then regular printing and embossing. Although this type of wallpaper has excellent performance, it has a high cost and is often used in star hotels, office buildings and other projects.
Second, classified by surface covering
1 plain paper wallpaper
This type of wallpaper is embossed or printed directly on a flat paper substrate. The paper substrate is divided into thicker single-layer paper and double-layer paper. Nowadays, more and more products use double-layer paper composite technology to achieve better D. The main features of plain paper wallpaper are good air permeability, good environmental performance, vivid colors and bright colors.
2 PVC Wallpaper
(1) PVC coated wallpaper (based on pure paper, non-woven fabric or woven fabric)
With pure paper, non-woven fabrics, and woven fabrics as substrates, PVC paste resin is sprayed on the surface of the substrate, and then processed by processes such as printing and embossing. After this type of wallpaper is foamed, it can produce a strong three-dimensional effect, and can be made into a variety of realistic texture effects, such as imitation wood, imitation brocade, imitation tiles, etc., have a strong texture and better ventilation Sex, able to withstand the erosion of grease and moisture, can be used in the kitchen and bathroom, suitable for almost all home places.
(2) PVC plastic surface wallpaper (based on pure paper or fabric)
This kind of wallpaper is covered with a layer of polyvinyl chloride film on the bottom layer of pure paper (or non-woven fabric, the bottom layer of the spinning fabric), and is made by the processes of compounding, embossing, and printing. This kind of wallpaper has fine print, good embossed texture, waterproof and moisture resistance, durable, easy maintenance. This kind of wallpaper is the most commonly used and widely used wallpaper at present, and can be widely used in all home and commercial places.
3 Nonwoven wallpaper
This type of wallpaper is directly printed on the surface of various types of non-woven materials, and the substrate is divided into single-layer non-woven fabric and double-layer non-woven fabric, both of which can be directly embossed, printed, or embossed on the surface thereof. . This kind of wallpaper is characterized by its soft color, soft handfeel, breathable and tear-resistance, and good space stability (that is, anti-shrinkage performance); the wall surface requirements during construction are not high, and the service life is very long. And in the second decoration can tear off the entire wallpaper without damaging the wall.
4 natural fabric wallpapers
Natural fabric wallpapers are made of natural materials such as grass, wood, leaves, stone, bamboo or precious species of wood cut into thin slices or filaments and adhered to the surface of pure paper or non-woven substrate; many manufacturers also use the first silk , wool, cotton, hemp and other fibers made into a thin surface layer, and then bonded to the paper or non-woven base fabric wallpaper made. This wallpaper is characterized by a simple and natural style, full of rich natural flavor, high environmental performance, no plastic taste, no static electricity, good air permeability.
5 metallic wallpaper
Metal texture wallpaper is based on gold and silver as the main color, through the vacuum coating process, combined with ordinary wallpaper production process in the wallpaper surface to gold, silver, copper, tin, aluminum and other metal materials texture. The main features are bright metal texture and reflective, stable performance, no discoloration, high value, fire protection, waterproof and so on.
6 special material wallpaper
Manufacturers produce wallpapers with special decorative effects or special features to meet the different needs of customers. One is the use of Pu (polyurethane) particles, mica, sandstone, sandblasting, crystal and other materials made by adhesive glue on the wallpaper surface, can produce special decorative and visual effects; the other is to some functional substances such as Diatomaceous earth, anion materials, etc. are added to the wallpaper production process. Such products can produce special functions such as humidity control, moisturizing, antibacterial, anti-mildew, and air purification.
