hydroxypropyl methyl cellulose for Brazil
Imagine building a house without cement? It sounds like a disaster waiting to happen. But with the right material, you can elevate your construction project to a higher level. Depending on the climatic and environmental conditions, one of the most popular and efficient materials used globally is
hydroxypropyl methyl cellulose (HPMC). Now, it's finally available in Brazil.
Hydroxypropyl methyl cellulose is a versatile and multi-purpose material. Its adaptability to different climatic conditions and environments has made it a go-to material for a wide range of construction projects. HPMC is a fully synthetic polymer material that is made from natural sources such as tree pulp and cotton linters. With its wide range of compatibility, HPMC is used in many different materials, including building materials and pharmaceuticals.
Brazil is well-known for its tropical climate, with high temperatures and humidity levels that are perfect for construction. Using HPMC in construction projects can help to improve the structure's durability, water resistance, and consistency. It can also enhance the workability of cement and mortar, reduce cracking, and improve yield.
In the past, HPMC was difficult to obtain in Brazil. But now, this excellent material is now readily available to builders and contractors in Brazil. The benefits of HPMC have already been enjoyed in other countries, such as Palestine, Malta, Indonesia, the United States, and Russia. Now, it's time for Brazil to realize how crucial this material is.
The use of HPMC can significantly improve construction and repair projects in Brazil. Builders and contractors who use HPMC in their projects can rest easy knowing that they've used a fundamental and trusted product to enhance their structures' quality. With HPMC's increased durability and strength, it can also improve construction quality and job site safety.
In conclusion, it's high time for builders and contractors in Brazil to explore the benefits of using HPMC in their building projects. With HPMC, you can be confident that structures will withstand the test of time and perform at the highest level. So, let's continue to promote the use of HPMC in Brazil, like Palestine, Malta, Indonesia, the United States, and Russia, and change the game in terms of the quality of construction projects in the region.
Faq
What are the other names for Hydroxypropyl Methyl Cellulose (HPMC)?
HPMC is widely used in industries such as construction materials, coatings, synthetic resins, ceramics, pharmaceuticals, food, textiles, agriculture, cosmetics, and tobacco. HPMC can be classified into architectural grade, food grade, and pharmaceutical grade based on its application. Currently, most domestically produced HPMC falls under the architectural grade category. In the architectural grade, a large amount of HPMC is used in putty powder, accounting for approximately 90% of its usage, while the rest is used in cement mortar and adhesives.
How many types does 2-Hydroxypropyl methylcellulose (HPMC) have, and what are the differences in their applications?
1. Whiteness: Although whiteness alone does not determine the usefulness of HPMC, higher-quality products usually have better whiteness.
2. Fineness: HPMC is typically available in 80 and 100 mesh sizes, with fewer options in 120 mesh. Finer particles generally indicate better quality.
3. Transmittance: When HPMC is dissolved in water and forms a transparent colloidal solution, higher transmittance indicates fewer insoluble impurities.
4. Specific gravity: Higher specific gravity is generally better. A higher specific gravity is often due to a higher content of hydroxypropyl, which results in better water retention.
What is the dosage of Hydroxypropyl Methylcellulose (HPMC) in putty powder?
The viscosity of HPMC is inversely proportional to temperature, meaning that viscosity increases as temperature decreases. When we refer to the viscosity of a certain product, it generally refers to the measurement result of its 2% water solution at 20 degrees Celsius.
In practical applications, in regions with large temperature differences between summer and winter, it is advisable to use relatively lower viscosity during winter for better construction. Otherwise, at low temperatures, the viscosity of the cellulose increases, resulting in a heavier feel during application.
Medium viscosity: 75,000-100,000 (mainly used for putty)
Reason: Good water retention.
High viscosity: 150,000-200,000 (mainly used for polystyrene particle insulation mortar powder and foamed glass bead insulation mortar)
Reason: High viscosity, reduces mortar dusting and sagging, improves construction.
However, in general, higher viscosity provides better water retention. Therefore, many dry mortar manufacturers consider using medium-viscosity cellulose (75,000-100,000) instead of low-viscosity cellulose (20,000-40,000) to reduce the dosage and costs.
What is the dosage of Hydroxypropyl Methylcellulose (HPMC) in putty powder?
The two main indicators most users are concerned about are the content of hydroxypropyl and viscosity. Higher hydroxypropyl content generally indicates better water retention. A higher viscosity also provides relatively better water retention (not absolute), and HPMC with higher viscosity is more suitable for cement mortar.
