[ Chinese Wardrobe ] The fragrant board is made of crop straw and slag as the main raw material. It is made of MDI glue and functional additive. It is made of high temperature and high pressure. It is not only smooth and smooth, the structure is even and symmetrical, the board surface is solid, and it has dimensional stability. Good, high strength, environmental protection, flame retardant and weather resistance, etc. It also has excellent processing properties and surface decoration properties, suitable for various surface decoration treatments and mechanical processing, especially for profiled edge processing. Compared with particleboard Advantage. Can be widely used to replace wood-based panels and natural wood.
The replacement of urea-formaldehyde resin with Wanhua modified MDI eco-adhesive for straw is the key to distinguishing formaldehyde from non-formaldehyde.
MDI is a general term for a large class of chemical adhesives. MDI in the general sense includes pure MDI, polymeric MDI, modified MDI, and mixtures thereof.
MDI is the most important raw material for the production of polyurethane. Due to the incomparable advantages of other synthetic materials in heat insulation, sound insulation, abrasion resistance, oil resistance and elasticity, polyurethane is the sixth largest plastic after polyethylene, polyvinyl chloride, polypropylene, polystyrene and ABS. It is used in the fields of national defense, aerospace, light industry, chemical industry, petroleum, textile, transportation, automobile, etc. It is an indispensable emerging material for economic development.
Because of the excellent stability and safety of MDI synthetic products, the downstream products of MDI are also used in fields that are closely related to people's livelihood and medical care, including lycra fibers for clothing, refrigerator liner materials, and even artificial organs implanted in the human body. Such as artificial blood vessels and heart valves.
At present, the global MDI production technology is only available in 8 countries (China, the United States, Germany, Japan) (Yantai Wanhua, Bayer, BASF, Huntsman, Dow, Japan NPU, Mitsui, Kumho Mitsui) In the hands. Wanhua Group is the only company in China that has MDI production technology and capabilities. Wanhua MDI technology belongs to China's national protection-grade patents and won the first prize of National Science and Technology Progress Award issued by the State Council of the People's Republic of China in 2007.
The MDI used in Wanhua Zero Realm Hexiang Board is a special modified MDI ecological adhesive developed by Wanhua Research Institute according to the characteristics of straw components. It is brown to dark brown liquid at room temperature. Based on PMDI (polymeric MDI), it improves the molecular structure of PMDI by reacting with biomass extracts, improves the affinity with straw fibers, has high reactivity, strong infiltration and penetration, and high chemical bond strength. The characteristics can overcome the waxy layer of straw, low surface free energy and high ash content, and form a solid whole with straw fiber.
