Perlite fireproof (door core) plate specifications:
300 x 500 x (20, 30, 40, 50, 60, 80, 100, 120 ) mm; or designed according to customer requirements, more than 17 thickness can be used for pattern.
According to GB8624-1997 "Classification Method of Combustion Performance of Building Materials" by the National Fixed Fire Extinguishing System and Refractory Component Quality Supervision and Inspection Center: continuous burning time Os, the mass loss rate is only perlite fireproof board is made of expanded perlite powder plus high temperature fireproof sticky The mixture is pressed by a mold and is suitable for filling materials of wooden fire doors and steel fire doors. It is an alternative product of aluminum silicate cotton and rock wool. With a bulk density of (260-300g/m3), high refractoriness (>1100°C), high compressive strength (0.9-2.OMPa), low thermal conductivity (≤0.051 W/MK), non-combustible, non-toxic, odorless, No pollution, etc., the combustion performance reached A grade by the National Building Materials Testing Center. The fireproof and heat insulation performance is higher than that of aluminum silicate cotton and rock wool. It is a new type of fire door filling material with low cost, excellent fireproof performance and environmental protection performance.
Sodium Hyaluronate is very important for skin because it improves moisturization, maintains skin resilience, and reduces damage in the lower part of skin when the skin is damaged. It also acts like lubricant by causing collagen, a main constituent of skin, to move smoothly in between cells.
But from the age of 25, Sodium Hyaluronate in human body will lose gradually, only remaining 65% of young skin at the age of 30, only 25% of young skin at the age of 50.
With the increase of the age and the loss of Sodium Hyaluronate, the skin will lose elasticity and luster, aging, wrinkles and relaxation will be generated gradually.
Sodium Hyaluronate is so water-friendly and it has functions of the best moisturizing factor and prevents diseases such as skin infections by preventing the penetration of external substances such as bacteria.
Therefore, it is regarded as an ideal "natural moisturizer" factor and widely used in cosmetics that suitable for different skins, climates and environments.
High molecular Sodium Hyaluronate can be formed breathable film on the surface of the skin, help the skin to lock moisture, and to prevent the invasion of bacteria, dust and ultraviolet, so that to protect the skin from damage.
Low molecular Sodium Hyaluronate, which is designed for better skin penetration, can penetrate into the dermis quickly, dilated capillaries slightly, promote blood circulation and metabolism, and so it has function of eliminating wrinkles, increasing skin elasticity and preventing skin aging.
