  How to choose the viscosity of HPMC   Hydroxypropyl methylcellulose is used in mortar, putty powder, water-based paint, and tile adhesive. Many manufacturers do not know how to choose the viscosity of hydroxypropyl methylcellulose   Putty powder, mortar, water-based paint, tile adhesive Hydroxypropylmethylcellulose   method/step   1. Many mortar and putty powder companies use hydroxypropyl methylcellulose as a chemical raw material. Some companies are not very clear about which viscosity hydroxypropyl methylcellulose to choose. Hydroxypropyl methylcellulose on the market Known as 4 0000 -5 0000   low-viscosity hydroxypropyl methylcellulose, there are also 10 0000 , 15 0000 , 20 0000   high-viscosity hydroxypropyl methylcellulose. Let's take a look at how various industries should choose hydroxypropyl methylcellulose.   2.   Cement mortar: Hydroxypropyl methylcellulose with a viscosity of 10W-20W should be selected for cement mortar. Hydroxy...

 The main purpose 1. Construction industry: As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. In plaster, gypsum, putty powder or other building materials as a binder to improve spreadability and prolong work time. It can be used as paste tile, marble, plastic decoration, paste reinforcement, and can also reduce the amount of cement. The water-retaining performance of HPMC prevents the slurry from cracking due to drying too quickly after application, and enhances the strength after hardening. 2. Ceramic manufacturing industry: It is widely used as a binder in the manufacture of ceramic products. 3. Coating industry: It is used as a thickener, dispersant and stabilizer in the coating industry, and has good compatibility in water or organic solvents. As a paint remover. 4. Ink printing: It is used as a thickener, dispersant and stabilizer in the ink industry, and has good compatibility in water or organic solvents. 5. Plastic: used as forming re...

  1. What is the main application of hydroxypropyl methylcellulose (HPMC)?   Answer: HPMC is widely used in construction materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into construction grade, food grade and pharmaceutical grade according to the purpose. At present, most of the domestic products are construction grade. In construction grade, putty powder is used in a large amount, about 90% is used for putty powder, and the rest is used for cement mortar and glue.   2. There are several types of hydroxypropyl methylcellulose (HPMC), and what are the differences in their uses?   Answer: HPMC can be divided into instant type and hot-dissolution type. Instant type products disperse quickly in cold water and disappear into the water. At this time, the liquid has no viscosity because HPMC is only dispersed in water without real dissolution. About 2 minutes, the viscosity ...
