Discussion on the Effect of the Addition of Hydroxypropyl Methyl Cellulose on the Properties of Mortar

Hydroxypropyl methylcellulose HPMC can significantly improve the water retention of mortar. A lower dosage of hydroxypropyl methylcellulose HPMC can significantly improve the water retention rate of mortar. When the dosage is 0.02%, the water retention rate increases from 83 % rose to 88%; when t... Read More

Different uses of different dry powder mortar additives!

1. Redispersible latex powder This mouth-watering material is a special high molecular polymer, which is made into powder after spray drying. After contacting with water, this powder can become an emulsion again, and has the same properties as an emulsion. After the water evaporates, it can form ... Read More
