Fireproof perforated composite rock wool board for noise reduction and sound reduction
2023-09-11 15:15
Color board core, gray paper surface, is the most economical and common variety. Suitable for use in places without special requirements, with a continuous relative humidity of no more than 65%. Due to price reasons, many people prefer to use 9.5mm thick ordinary paper faced gypsum board for ceiling or partition walls. However, due to its thin and low strength, 9.5mm ordinary paper faced gypsum board is prone to deformation under humid conditions. Therefore, it is recommended to choose gypsum boards with a thickness of 12mm or more. At the same time, using thicker sheets is also an effective means to prevent joint cracking. Firstly, it is worth noting that gypsum board has been widely used as internal partition walls, and lightweight building materials with large production and wide application are very common internationally.

Fireproof perforated composite rock wool board for corridor sound absorption, easy to clean
Another advantage of paper faced gypsum board is that it has excellent fire resistance. When exposed to fire, it releases the combined water and absorbs a large amount of heat, delaying the increase in ambient temperature. According to the fire detection center, the fire resistance limit of paper faced gypsum board partition walls can reach 4 hours. Therefore, using it as a home decoration material is very safe. Paper gypsum board has a large porosity, a well distributed pore structure, good breathability, and has a regulating effect on indoor humidity. When indoor humidity is high, it can absorb moisture, and when the air is dry, it can release some moisture. Make your home life more comfortable and healthy.

Why does the rubber head emit oil
The "painter" in silicone - transfer printing silicone, because transfer printing silicone has excellent characteristics such as low viscosity, good flowability, no shrinkage, easy oiling, clear transfer printing patterns, delicate gel, good resilience, and multiple transfer printing times, transfer printing silicone is used to manufacture transfer printing. Transfer printing silicone requires fine gel, no impurities, no particles, and good resilience. Transfer printing silicone uses high-quality raw materials, Added American DuPont Teflon high-temperature resistant new material, processed at high temperature, with advantages such as wear resistance, high temperature resistance, and good printing effect. Therefore, it is widely used in the printing of irregular patterns such as plastic toys, electroplating products, electronic toys, trademarks, communication equipment, craft gifts, stationery, etc., and is also known as the painter in silicone.

SP conductive carbon black for lithium batteries
Conductive carbon black SP has always been an important additive for the positive electrode of lithium-ion batteries. Its function is to improve the electron transfer between the positive electrode active material coating and the collector, reduce the interface contact resistance of the motor, and play a depolarizing role. The reinforcement performance of conductive carbon black SP has the following characteristics: (1) high hardness, (2) "high heating performance," (3) high elasticity, and all other average characteristics.
