Types of artificial stone countertops
1, acrylic artificial stone
The artificial stone with polymethyl methacrylate (PMMA) as matrix and superfine aluminum hydroxide as filler is acrylic artificial stone. Because PMMA is a flowing resin, the pressing process is complicated and difficult. At present, the acrylic sheet produced in China does not contain unsaturated polyester or other resins, which is also called acrylic stone. This kind of stone has high hardness and toughness, can be bent, and has excellent weather resistance and mechanical properties, and will not naturally crack under the condition of large temperature difference.
2. Composite acrylic artificial stone
Composite acrylic countertops are the most cost-effective of all artificial stone countertops. Its main components are saturated resin about 20% acrylic acid, aluminum hydroxide and particles, 65% other materials about 2% (depending on different colors). Its price, gloss, hardness and corrosion resistance are moderate, and it is the mainstream product of cabinet countertops.
3. Aluminum powder polyester artificial stone
Artificial stone, commonly known as aluminum powder board, is polymerized with unsaturated polyester resin as adhesive and filled with ATH. Environmental protection, non-toxic, non-radioactive, and has excellent processing and mechanical properties, oil resistance, no cracking.
4, calcium powder polyester artificial stone
Commonly known as calcium powder board. Because calcium powder is mineral powder, it may contain radioactivity; The machinability of long products is poor,
Easy to collapse, poor mechanical properties, high brittleness, easy cracking of finished products and short service life; Poor anti-pollution ability, easy to absorb water and oil, forming spots; Combustible but not fireproof. 5. Celery stone is also called quartz stone.
Quartz stone is a kind of stone that only appeared in recent two years. Contains natural timeliness, hard texture, natural luxury, wear resistance, corrosion resistance and no leakage. However, the processing and splicing are complicated and there are splicing traces. At present, Celite from Spain is popular in the market.
6. Crystal stone
Compared with beryl, crystal stone has not changed much in essence, but more materials with large particles and high transparency are used in color matching and pigments. After high temperature tempering, there are more pores on the crystal table than ordinary beryl.
7. Marble
Marble is a kind of artificial stone with higher cost than crystal stone. Its pattern imitates natural grain and its texture is hard. Because of its defects in processing and particle docking,
It has not been used on a large scale, and is generally used for packaging other external walls, columns and lighting. Artificial stone cabinet countertop grade
1, high-grade artificial stone (pure acrylic and composite acrylic artificial stone)
Acrylic content accounts for 15%-20% of the total material content, and the brand is generally made in China. The performance of this material is basically the same as that of imported artificial stone and soy sauce.
The board is elastic, it is not easy to break when cutting bones on it, and the price is also very advantageous. The retail price of high-end cabinet shops is around 1080, which is very cost-effective. 2, intermediate artificial stone pure aluminum artificial stone (aluminum table)
The raw material of intermediate artificial stone is aluminum powder+resin+pigment. Compared with acrylic artificial stone, it contains no acrylic component, but uses the filler of high-grade tableware as the agent of acrylic. The advantage of this material is environmental protection, and its price is superior to that of acrylic and composite huoreg. Soy sauce and vinegar will not bleed when poured on it for a long time, but the performance of this product is average when it is bent after heating, which is suitable for household cabinet countertops and not suitable for special-shaped processing in high-end places.
3. Low-grade artificial stone
The raw materials of low-grade artificial stone are calcium powder+aluminum powder+resin+pigment. The surface of this artificial stone plate may not be much different from the above-mentioned plate in the eyes of laymen, but because calcium carbonate is used in the raw material,
Even if the soy sauce residue on the surface of the plate does not exceed 24 hours, it will definitely bleed. Calcium carbonate has high hardness, the plate is inelastic, and it is easy to break after bone cutting. Long-term use will change color, and serious will fade and change color. Compared with quartz stone, acrylic is a soft material. If the force is particularly strong, the Shi Ying slate is too hard, that is, too brittle, it will break. Acrylic artificial stone plate is elastic, can disperse strength, and is not easy to break, so it is a very good countertop material.
Will break, and acrylic artificial stone plate is elastic, can disperse strength, not easy to break, so it is a good countertop material.
