Performance of HPMC for putty powder added to putty powder:

1) After HPMC for putty powder is added and hydrated, a thin latex film is formed between the putty powder particles. This film has a sealing effect and improves the surface dryness of the putty powder.

2) HPMC for putty powder has good water retention, so that enough water molecules are stored inside the putty powder, thus ensuring the hydration and hardening of the putty powder and the complete development of the strength, increasing the strength of the putty powder and at the same time. The cohesion of the putty powder makes the putty powder have good plasticity and flexibility, and reduces the shrinkage and deformation of the putty powder.

3) After HPMC for putty powder is added to the putty powder, the methoxy and hydroxypropyl groups on the molecular chain will interact with the calcium and aluminum ions in the putty powder to form a viscous gel and fill the gaps in the putty powder. , Improve the compactness of putty powder, play the role of flexible filling and reinforcement. However, when the composite matrix is compressed, the polymer cannot play a rigid supporting role, so the strength and crushing ratio of the putty powder decrease;
