How to test the viscosity of hydroxypropyl methylcellulose?

By |2022-09-26T06:46:36+00:00September 26th, 2022|Industry News|

Hydroxypropyl methyl cellulose for construction needs to avoid the infiltration of water into the wall, and the appropriate amount of water is retained in the mortar, which can make the cement fully produce good performance and perform the effect of water and water. Hydroxypropyl methyl cellulose The viscosity of the base cellulose in the mortar

How to use CMC and its contraindications

By |2022-09-21T02:59:33+00:00September 21st, 2022|Industry News|

When using CMC in the food production process, it is necessary to dissolve the CMC first. There are two usual methods— 1. Mix CMC with water directly to prepare a paste-like glue, then use it for later use. When configuring CMC paste, first add a certain amount of clean water to the batching tank with

CMC vs Sodium Alginate

For a long time, the reactive dye printing paste is mainly sodium alginate. With the rising price of sodium alginate and some defects exposed in the process of rotary screen and flat screen printing. Some other natural polysaccharide pastes or synthetic pastes have emerged as alternatives to sodium alginate. This article mainly compares sodium carboxymethyl

Determination of cellulose ether quality by HPMC combustion

By |2022-06-21T06:12:41+00:00June 21st, 2022|Industry News|

The quality of cellulose ether is influenced by many aspects, so how can we judge the quality of cellulose ether from the ash content of HPMC after combustion? First we need to understand what ash is. (1)Ash, also known as scorch residue, can simply be understood as impurities inside the product. They are naturally produced

Adjustment of cement self-levelling formulations for different environments

By |2022-06-21T03:50:46+00:00June 21st, 2022|Industry News|

Changes in temperature and humidity have a very important impact on self-levelling construction, and poor solutions can lead to a range of quality problems. Basis for adjustment of cement self-levelling formulations at low temperatures. It is well known that cement self-levelling formulations are complex and have many components. Some raw materials have a glassing temperature

What is the effect of cellulose ether viscosity on the performance of gypsum mortars?

By |2022-06-16T02:58:38+00:00June 16th, 2022|Industry News, Product Applications|

Viscosity is an important parameter for the performance of cellulose ethers. Generally speaking, the higher its viscosity, the better the water retention effect of the gypsum mortar. However, the higher the viscosity, the higher the molecular weight of the cellulose ether and the corresponding decrease in its solubility, which has a negative effect on the

Notes on the use of cellulose ethers in putty powders

By |2022-06-16T02:55:08+00:00June 16th, 2022|Industry News, Product Applications|

Cellulose is commonly used in the fields of insulation mortar masterbatch, putty powder, asphalt roads and plaster products. It is used to improve and enhance the characteristics of building materials and to enhance the stability of production and construction suitability. Today, we would like to introduce you to the precautions caused by cellulose when using

Several factors influence the viscosity of hydroxypropyl methyl cellulose

By |2022-06-16T02:50:59+00:00June 16th, 2022|Industry News|

The addition of hydroxypropyl methyl cellulose(HPMC) to the cementitious material has a thickening effect and the amount added determines the water requirement of the cementitious material and therefore affects the yield of the mortar. Several factors affecting the viscosity of hydroxypropyl methyl cellulose(HPMC): The higher the degree of polymerisation of the cellulose ether, the higher

HPMC vs HEMC(3)
