Cellulose ether includes many cellulose products. There are many cellulose products that can be used as water-retaining agents and thickeners. This article mainly introduces the cellulose ether hydroxypropyl methylcellulose (HPMC). When it comes to water-retaining, people may think of the effects of preventing water evaporation and loss, but the water-retaining effect of cellulose ether (HPMC) […]

Mortar adhesive products: Hydroxypropyl methylcellulose (HPMC) Building-grade mortar adhesive is a polymer (HPMC) that can enhance the bonding of cement-based premixed dry mixes. The mortar with the adhesive has good flexibility and bonding, good anti-sagging, water retention, and water resistance. It is easy to operate and can improve the bonding strength and tensile strength to […]

The Water Retention Functions and Principles of Hydroxypropyl Methylcellulose The HPMC mainly plays a role in water retention and thickening, able to effectively improve the bond force and sag resistance of slurry. Air temperature, humidity, wind pressure and other factors will affect the evaporation rate of water in cement mortar and gypsum-based products. Therefore, in […]

The mechanism by which concrete shrinkage cracking occurs is as follows. In setting and hardening of concrete, the volume will change and the set cement will generate heat of hydration. Due to different rates of temperature increases and decreases on the surface or in the inner part of components, shrinkage deformation of concrete will be […]

In the realm of modern construction, materials play a pivotal role in ensuring structural integrity, durability, and aesthetic appeal. Among the myriad additives used in construction materials, Hydroxypropyl Methylcellulose (HPMC) stands out as a versatile and indispensable component. Enhancing Workability and Performance HPMC is widely employed as a rheology modifier in various construction materials, including mortars, renders, […]

1. Cement Mortar HPMC acts as a multifunctional additive in cement mortar formulations, offering a myriad of benefits. Firstly, it enhances the dispersion of cement-sand, ensuring uniformity and consistency throughout the mixture. This improved dispersion translates to enhanced mortar plasticity, allowing for easier application and shaping during construction activities. Moreover, HPMC significantly boosts the water-holding capacity of […]

Hydroxypropyl methyl cellulose（HPMC）is selected from highly pure cotton cellulose as raw material, treated with lye at 35-40 ° C for half an hour, pressed, The cellulose was pulverized and appropriately aged at 35 ° C so that the average degree of polymerization of the obtained alkali fibers was within a desired range. The alkali fiber […]

At present, gypsum mortar building materials as a new type of building materials, with its good thermal insulation, fire prevention, light weight and air humidity regulation, green safety and environmental protection and other basic characteristics, are more and more widely used in modern construction projects. Due to the use of traditional cement mortar for many […]

Cellulose ethers, such as Hydroxypropyl Methyl Cellulose (HPMC), are essential in the construction industry for their ability to enhance the properties of various building materials. Here’s a more detailed look at how HPMC and other cellulose ethers are used as construction chemicals: Key Uses of Cellulose Ethers in Construction Tile Adhesives: Role: HPMC improves the […]
