One or more of hydrochlorate, hydroxide.Water-soluble high-molecular material plays the role of guaranteeing low-temperature bond strength, water-soluble
Inorganic salts are main binders, guarantee that core strength, organic acid play the role of adjusting pH value under high temperature degree.Due to adding
Agent and water is added to be mixed into solution, in subsequent heating process, moisture gradually evaporates, the components such as inorganic salts and water soluble polymer
Particle surface crystallization precipitation is gradually depended on because of the decline of solubility and forms bonded bridge, to obtain certain initial strength.Due to
The solution degree of inorganic salts in water is relatively low, and the amount of solution of droplet ejection spray head injection is relatively small, therefore, individually sprays
