Question:

Gypsum board used in the expansion agent

Gypsum board used in the expansion agent

Answer:

When the foaming agent and gypsum hydration generated intermolecular force - hydrogen chain, resulting in steric hindrance, resulting in gypsum lattice structure of the lack of excitation gypsum activity, to accelerate the formation of network-like gypsum skeleton, so as to enhance the strength of gypsum board , Reduce the capacity of gypsum board, greatly saving raw materials, fully improve the physical properties of gypsum board.
Gypsum board foaming agent for the gypsum board in the production process gypsum foam.
Prepared by anionic surfactants and foam stabilizer, diluted with water several times with a blowing agent into a rich and delicate foam, and gypsum paste made of gypsum board. ?????? Sodium dodecyl sulfate (K12), fatty alcohol polyoxyethylene ether sulfate (AES), sodium α-alkenyl sulfonate and other anionic surfactants can be used as a paper gypsum board Blowing agent. This kind of foaming agent has high foaming factor and low cost. But the foam stability is poor, usually with the use of foam stabilizer. At present, the main component of gypsum board foaming agent is still sodium dodecyl sulfate (K12), which is divided into solid product (above 93) and liquid product (30% aqueous solution).
