HPMC EIFS:ssä: Kuinka tehokkaita 7 toimintoa ovat!

1. Johdanto

If you want to apply HPMC in EIFS, You need to know the properties of HPMC. MelaColl is a trademark for MIKEM’s cellulose products and derivatives. MelaColl™ hydroxypropyl methyl cellulose (HPMC) is one of the members of the cellulose ethers where hydroxyl groups have been alternated for one or more of the three-hydroxyl groups in the cellulose. Our HPMC is a water-loving, biocompatible, and biodegradable polymer that has several ranges of applications in construction. This polymer dissolves in polar organic solvents, which implies that it is compatible with both non-aqueous and aqueous solutions. Having such distinct solubility properties, makes HPMC possess solubility in both high and low-temperature organic solvents.

2. About EIFS

EIFS, which is the abbreviation for Exterior Insulation and Finish System, is also referred to as ETICS (External Thermal Insulation Cladding System). It is a term related to the construction industry. EIFS is concerned with the building of non-bearing cladding systems that offer additional protection to the external walls of buildings. The purpose of performing an EIFS on a construction building is for providing insulation to heat, prevent the penetration of water through the walls, and give a stylish finish surface.

External insulation is actually a layer of insulation film placed on the outer wall of the building to ensure that the material of the main body of the outer wall is free from the effects of temperature changes such as sun exposure and cold. This approach can maximize the life of the building walls and ensure safety. This is a very safe and healthy thermal insulation practice, which is strongly advocated by the state.

3. Functions of HPMC in EIFS

For most Engineers and project managers on construction sites, the chemical used to achieve an exterior insulation and finish system (EIFS) is the hydroxypropyl methylcellulose (HPMC).

• This cellulose has different properties that make it effective and preferred for EIFS. HPMC performs a key role in making insulated exterior walls while maintaining a smooth and attractive finish.
• Experts depend on the properties of HPMC that makes it the best option for this construction work. Some of these properties include HPMC high resistance to sagging, water retention quality, and extended embedding time.
• However, there are certain inherent qualities of HPMC that should be taken into consideration when using it for EIFS. These qualities include the viscosity, PH level, Gel temperature, particle size, light transmittance, and weight. HPMC water retention property is affected by these factors; hence, experts need to understand each properly.

4. 7 Reasons for Applying MelaColl™ HPMC in EIFS

Using MelaColl™ hydroxypropyl methylcellulose (HPMC) for Exterior Insulation and Finish System (EIFS) offers the following benefits:

• Parempi tarttuvuus: The materials of the exterior walls are firmly held together by using this cellulose material.
• The adequate wetting ability for EPS board and substrate: HPMC in EIFS improves how effective the wetting of the board and substrate.
• Reduced air entrancement and water uptake: The air spaces within the external walls of buildings become resistant to the passage of air, which may weaken the structure. Water uptake is reduced as well, HPMC in EIFS increases the water retention of the walls and this does not allow water uptake.
• Good consistency: HPMC in EIFS allows the walls to maintain a consistent finish look and appearance, and this adds beauty to the walls.
• Good anti-bleeding: HPMC in EIFS prevents the occurrence of bleeding within the exterior walls
• Anti-crack and anti-shrinkage: The occurrence of wall cracks and shrinkages are prevented with the use of Hydroxypropyl methylcellulose.
• Hyvä työstettävyys: It also offers good workability. The designated particle size distribution assures quick or lumps-free dissolution. It is suitable for all conventional mineral and organic binders.
