At present, medical furniture not only has a wide variety of materials, but also presents the characteristics of the combination of various materials. At present, the materials used for medical furniture mainly include wood, artificial board, veneer material, stone, plastic, metal, glass, hardware, etc. According to the different functional requirements of medical furniture and the different properties of materials, the corresponding structure and technology should be used to design furniture products.
Stone material divides natural stone material and man-made stone material. Artificial stone is widely used in medical furniture. Artificial stone is actually a kind of “polymer material polymer”, with non-toxic, non-radioactive, flame retardant, non-oil, non-seepage, antibacterial, mildew-proof, wear-resistant, impact resistance, easy maintenance, seamless splice, modeling and easy to take care of the characteristics.
Artificial stone because of excellent acid and alkali resistance, easy to clean, seamless, bacteria have no place to hide, and is widely used in hospital table tops and laboratory table tops and other strict medical furniture, can meet the requirements of aseptic environment.
Classification of artificial stone
According to the different binder used, can be divided into organic artificial stone and inorganic artificial stone two kinds. According to the engineering of different production process, and can be divided into polyester compound artificial stone, artificial stone in silicate type artificial stone, sintering type artificial stone four types, of which organic kind of polyester type is the most commonly used, its physical and chemical properties are the best, so in medical furniture USES the artificial stone is polyester man-made stone, also known as artificial stone resin type. Resin type artificial stone is unsaturated polyester resin as cementing agent, unsaturated resin and aluminum hydroxide filling material as the main material, by stirring, shallow injection, heating, polymerization and other processes. It has a certain toughness and hardness, but afraid of sharp scratches, corrosion resistance, light resistance, can also make a variety of modeling under high temperature conditions, and the product life is very long, has the advantages of non-toxic harmless, not discoloration. In addition, polyester artificial stone surface renovation, grinding, polishing is also easy.
However, due to the high cost of aluminum hydroxide, there are undesirable manufacturers in the production of resin artificial stone to add calcium powder, namely calcium carbonate. Generally, the life cycle of medical furniture using artificial stone is about 10 years. Once the table surface is adulterated, the life span is only 1-2 years.
