Hydroxypropyl methyl cellulose ((HPMC), the raw material cellulose, can be refined cotton or wood pulp. It is necessary to crush it before or during the alkalization process. The crushing is done by mechanical energy. Destroy the aggregated structure of cellulose raw materials to reduce crystallinity and degree of polymerization, increase its surface area, thereby improving

Following the addition of hydroxypropyl methylcellulose to 0.5% in foamed concrete, the slump decreased slightly. The data clarified that when the content of hydroxypropyl methyl cellulose does not exceed 0.05%, the participation of hydroxypropyl methyl cellulose can significantly improve the fluidity and viscosity of the foam concrete slurry. After the hydroxypropyl methyl cellulose is dissolved,

rdp powder-Use environment and precautions of redispersible latex powder Re-dispersible latex powder is a powder adhesive made from a special emulsion (high molecular polymer) spray-dried. This powder can be quickly redispersed to form an emulsion after contact with water, and has the same properties as the initial emulsion, that is, a film can be formed
