Hydroxypropyl methyl cellulose is a kind of nonionic cellulose ether which is made from refined cotton, a natural high polymer material, through a series of chemical processing. Mainly used in the construction industry: water resistant putty powder, putty paste, steel putty, coating glue and masonry plastering mortar, dry powder insulation mortar and other dry building materials.
     Hydroxypropyl methyl cellulose water retention effect is good, easy construction, viscosity has a variety of options, can achieve a variety of needs.
    Hydroxypropyl methyl cellulose ether with good performance can significantly improve the construction performance, pumping and spraying performance of mortar, and is an important additive in mortar.
    1, hydroxypropyl methyl cellulose ether has excellent water retention performance, widely applicable to all kinds of mortar, including masonry mortar, plastering mortar and ground leveling mortar, improve the water secretion of mortar.
   2, hydroxypropyl methyl cellulose ether has a significant thickening effect, improve the construction performance and workability of mortar, change the fluidity of the product, to achieve the desired appearance effect, improve the fullness of mortar and use volume.
   3, hydroxypropyl methyl cellulose ether because it can improve the cohesiveness and operability of mortar, overcome the common problems of ordinary mortar shell, empty drum, reduce material, save materials, reduce costs.
   4, hydroxypropyl methyl cellulose ether has a certain retarding effect, can ensure the operating time of mortar, improve the plasticity of mortar and construction effect.
   5, hydroxypropyl methyl cellulose ether can introduce an appropriate amount of bubbles, can greatly improve the anti-freeze performance of mortar, improve the durability of mortar.
   6, cellulose ether is combined with physical and chemical effects of water retention and thickening, in the hydration process can produce cause micro-expansion performance of the material, so that the mortar has a certain micro-expansion performance, prevent mortar in the late hydration process due to shrinkage caused by cracking, improve the service life of the building.
