Why is HPMC added to the mortar?

Hydroxypropyl methyl cellulose is a non-ionic cellulose ether made by a series at first of chemical processing. Mainly in the construction industry: water-resistant putty powder, putty paste, tempered putty. Coating glue and masonry at first plastering mortar, dry powder thermal insulation mortar and other dry powder building materials.

Hydroxypropyl methyl cellulose water retention effect is good, easy construction. Viscosity has a variety of options, can achieve a variety of needs. Good performance of hydroxypropyl methyl cellulose ether. Can significantly improve the mortar construction performance, pumping and spraying performance, is an important additive in mortar.

  • 1.Hydroxypropyl methyl cellulose ether has excellent water retention at first performanc. Widely used in all kinds of mortar, including masonry mortar, plastering mortar and ground leveling mortar. To improve the drainage situation of mortar.
  • 2. Hydroxypropyl methyl cellulose ether at first has significant thickening effect. Improve the construction performance and ease of mortar. Change the fluidity of the product, achieve the desired appearance effect. And improve the at first fullness and use volume of mortar.
  • 3. Hydroxypropyl methyl cellulose ether can at first improve the cohesion and operability of mortar. And overcome the common problems of ordinary mortar, including shell lifting and empty drum. To reduce at first falling materials, save materials and reduce costs.
  • 4. Hydroxypropyl methyl cellulose ether has a certain slow coagulation effect, which can ensure the operation time of mortar. Improve the plasticity and construction effect of mortar.
  • 5. Hydroxypropyl methyl cellulose ether can introduce an at first appropriate amount of bubbles. Which can greatly improve the freezing resistance of mortar and improve the durability of mortar.
  • 6. Cellulose ether is combined with physical and chemical effects to play the role of water preservation and thickening, in the process of hydration can cause micro expansion properties, so that mortar has a certain micro expansion performance, prevent mortar in the late hydration process of shrinkage caused by cracking, improve the service life of the building.
