Wood pulp cotton rag manufacturers introduce compressed wood pulp cotton
Wood pulp cotton is foamed with polyether, a sponge like foamed bread. It can be foamed by mechanical equipment or artificially surrounded by wooden boards. The foamed sponge is like a square loaf. Use a slicing machine to go through the slicing process and cut the thickness according to different requirements. The hardness of this material can also be adjusted. Although the hardness and density of foamed sponges are directly related, they are also related to different additive formulations. Therefore, in the industry, there are high-elasticity foaming sponges, gray super-foaming sponges, black gray super-foaming sponges, and soft sponges.
When designing and using foamed sponge products, reasonable and scientific matching should be carried out according to different shapes and structures. Generally, sponges with different elasticity and density are divided into three parts: upper, middle and lower.
There is a kind of material called fireproof cotton in the sponge. In fact, before the sponge is foamed, a fireproof agent, such as chlorine and bromine, is added to the material formula to make the sponge produce smoke when it catches fire, which plays a flame retardant role.
At present, the product prices and brands in the sponge market are changing too fast. Everyone must look for good brands when purchasing.
