Types of HEMC For Mortars

The HEMC for mortars produced by our company mainly include the following types:

Hydroxyethyl Cellulose Fine Powder

Kemox HPMC has very good uniformity. Its methoxy and hydroxypropoxy groups are evenly distributed along the cellulose molecular chain, which can improve the ability of the oxygen atoms on the hydroxyl and ether bonds to associate with water to form hydrogen bonds so that the free water becomes bound water.

Hec Thickening Agent

Cement and gypsum based skim coats/wall putty are used as the final coating on different substrates and have a thickness of 2-4 mm. It’s a smooth, sand-free, hydraulic material and skim coating on interior and exterior projects are applied in multiple layers.

Advantages of Adding HEMC For Mortars

Extended Open Time

HEMC increases the open time of the mortar, allowing workers enough time to navigate adjustments and finish the job, ensuring a higher quality finish that looks better.

Improved workability

HEMC improves the workability of the mortar, making it easy to work and spread, it ensures a smoother consistency of the mortar, reduces the physical effort of the workers during the construction process and improves the efficiency of the workers.

Increased Adhesion

HEMC enhances the bonding strength of the mortar and ensures a stronger bond between the mortar and the substrate, which improves the structural integrity and enhances the life of the product.

Sag Resistance

HEMC helps to reduce sagging so that thicker layers can be constructed without the risk of mortar slipping or sliding. This is particularly beneficial for vertical and elevated applications.

Superior water retention

With excellent water retention properties, HEMC ensures that the mortar stays hydrated for longer periods. This leads to better curing and reduces the risk of cracks and shrinkage.

Consistency and Uniformity

The inclusion of HEMC in dry mix mortar ensures consistent quality across batches, leading to uniform performance and reliability in construction projects.

What Are the Common Properties of HPMC and HEMC?

Solubility - The solubility of cellulose ethers in alkaline aqueous solutions, water, or organic solvents depends on the nature of the etherifying groups and the degree of substitution (DS).

Viscosity of Aqueous Solutions - Influencing Factors of Cellulose Ether Viscosity:
– Polymer chain (degree of polymerization or molecular weight).
– Solution concentration.
– Temperature.

Stability - Cellulose ethers are susceptible to cellulase enzymes and microorganisms. Stability increases with a higher degree of substitution or uniformity of substitution.

Toxicity and Ecological Impact - Cellulose ethers are non-toxic. They can undergo biodegradation. So, long-term storage and accumulation should be avoided.

Uses - HEMC and HPMC powders are two commonly used cellulose ethers in dry-mix mortars for construction applications.

Dissolving Method of HEMC For Mortars

Add a specified amount of clean water to the container.

Add hydroxyethyl methylcellulose under low-speed stirring, and stir until all materials are completely wet.

Add other components of the formula and stir well.

Safety Precautions for the Use of HEMC For Mortars

Hydroxyethyl methyl cellulose (HEMC) is becoming more popular in construction. It’s important to look at its environmental and safety effects. HEMC is seen as eco-friendly because it comes from natural cellulose and breaks down easily. This makes it a good choice for building materials.

From a safety standpoint, HEMC is safe and non-toxic when used correctly. Its production follows strict quality rules and safety standards, which protect workers and users. Also, using HEMC in building materials doesn’t harm health if done as the maker says.

Experts suggest following safe handling and use guidelines for HEMC. This includes wearing the right protective gear, ensuring good airflow, and disposing of waste properly. By focusing on safety and the environment, the construction world can use HEMC wisely.

FAQ

Q: What is HEMC?

A: HEMC (hydroxyethyl methylcellulose) is a non-ionic cellulose ether made from natural polymer cellulose through a series of chemical processes. It is white or off-white powder, odorless, non-toxic, and can be dissolved in cold water to form a transparent viscous solution.

Q: How does HEMC affect the water retention of mortar?

A: HEMC can absorb and retain a large amount of water, forming a moist film to prevent the water in the mortar from evaporating too quickly, thereby maintaining the moisture and workability of the mortar.

Q: What effect does the amount of HEMC added have on the performance of mortar?

A: When the amount of HEMC added is within a certain range, the performance of the mortar can be significantly improved. However, adding too much or too little may cause the performance of the mortar to deteriorate. Therefore, the amount of HEMC added needs to be strictly controlled.

Q: How does HEMC improve the workability of dry mix mortar?

A: HEMC enhances the consistency and spreadability of the mortar, making it easier to apply and work with. This reduces the effort needed during application and ensures a smoother finish.

Q: How do I determine the correct dosage of HEMC for my dry mix mortar?

A: The optimal dosage of HEMC depends on the specific requirements of your project and the properties of the other ingredients in your mortar mix. It's recommended to start with a small percentage (typically 0.2-0.5% by weight) and adjust based on performance.

Q: What are the different grades of HEMC available for building materials?

A: There are many grades of HEMC for different construction needs. Each grade has its own molecular weight and chemical makeup. This affects how well it works in cement, adhesives, and mortars.
