Yan'anCalcium carbonate whisker

Calcium carbonate whisker is another new type of inorganic filling after nano calcium carbonate, non-toxic, odorless, white pine-like solid (under the microscope for needle-like single crystal) as a new generation of filling material The product has the following properties and characteristics: Comprehensive performance, high mechanical strength, and can reduce vibration, skid resistance, noise reduction and wave absorption during use; Good comprehensive performance, high friction coefficient, high wear resistance and heat resistance; Stable friction performance, good heat recession and heat recovery performance, especially the filling of calcium carbonate whiskers organically integrates friction increase and wear reduction in a system, with excellent high temperature friction and wear performance. Can reduce aromatic fiber, steel fiber, copper, the amount of potassium titanate and other high-value materials greatly reduces the cost of friction materials; the powder produced after the friction of the product is non-toxic and has little pollution.

Yan'anInorganic cotton

Inorganic fiber cotton as an efficient insulation material, compared with organic polystyrene, polyurethane and other foam insulation materials, fire non-combustible (Class A), does not have flame ignition and transmission, and its light bulk density, low thermal conductivity, fire prevention and non-toxic, stable chemical performance, long service life, is recognized as an ideal insulation material at home and abroad, widely used in construction and other industries. However, in the specific application process, inorganic fiber cotton board still has some problems, such as inorganic fiber cotton board moisture absorption is more serious, resulting in its drooping off; tensile strength is low, will peel from the wall; and the system protective layer cracking.
