The product application range of hydroxypropyl methylcellulose includes: masonry mortar, board joint filler, cement-based plaster, gypsum plaster and plaster products, water-based paint and paint remover, tile adhesive, self-leveling floor Due to the wide range of applications such as materials and formed concrete slabs, whether it is used as a binder, stabilizer, or other aspects, it can only be used after it is dissolved.

Hydroxypropyl methylcellulose is an important raw material for building materials, and it is widely used because of its excellent water retention and thickening properties. An important indicator of hydroxypropyl methyl cellulose is its viscosity.

Hydroxypropyl methylcellulose is a non-ionic cellulose alkyl hydroxyalkyl mixed ether obtained by cellulose alkalization, etherification, neutralization and washing. Hydroxypropyl methylcellulose is a water-soluble non-ionic cellulose ether.

Ordinary concrete is silicate. In the case of air or water vapor, silicate ions will undergo a hydrolysis reaction, and the generated hydroxyl groups and metal ions will combine to form hydroxides with less solubility (alkaline chemical properties).

Enhance the adhesion to the surface of the masonry, and can enhance the water retention, so that the strength of the mortar can be improved. Improve lubricity and plasticity to improve construction performance, easier to apply, save time, and improve cost-effectiveness.

In order to obtain accurate and reliable hydroxypropyl methylcellulose viscosity measurement data, several points must be noted:

1. The performance indicators of the instrument must meet the requirements of the national metrological verification regulations.

For the calculation of the insoluble content of hydroxypropyl methylcellulose, the remaining residue should not exceed 5mg (0.5%). Add 300mL of distilled water and set aside; dry the sample and the No. 1 vertical melting glass crucible in advance. The washing liquid is also added to the above glass crucible and filtered, put into a beaker,

You may be strange when it pertains to hydroxypropyl methyl cellulose, however when it involves cement, mortar, and concrete, every person is familiar with it. HPMC for cement mortar is a crucial additive in concrete, mortar, and also concrete. Let’s have a look at hydroxypropyl. What are the results of methyl cellulose on the residential or commercial properties of cement, mortar and concrete.
