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
HPMC is a non-ionic type of cellulose ether. So, what does "non-ionic" mean?
The gelation temperature of HPMC is related to its methoxy content. The lower the methoxy content, the higher the gelation temperature.
What is the application of HPMC in putty powder, and what causes the formation of bubbles in putty powder?
HPMC has three functions in putty powder: thickening, water retention, and facilitating construction. It does not participate in any reaction. The formation of bubbles in putty powder can be caused by two reasons: (1) Excessive water content. (2) Applying another layer on top before the bottom layer has dried, which can also lead to the formation of bubbles.
What are the formulations for interior and exterior wall putty powder?
The cold-water soluble type of HPMC is surface-treated with formaldehyde, allowing it to disperse rapidly in cold water but not truly dissolve. It only dissolves when the viscosity increases. The thermal soluble type does not undergo surface treatment with formaldehyde. A higher dosage of formaldehyde results in faster dispersion but slower viscosity increase, while a lower dosage has the opposite effect.
What is the relationship between the gelation temperature of hydroxypropyl methylcellulose (HPMC) and something else?
In the application of HPMC in putty powder, it plays three roles: thickening, water retention, and facilitating construction. Thickening: Cellulose can thicken the mixture, maintain uniform suspension, and prevent sagging. Water retention: It slows down the drying process of putty powder and assists in the reaction of lime and calcium in water. Construction: Cellulose acts as a lubricant, improving the workability of the putty powder. HPMC does not participate in any chemical reactions; it only serves as an auxiliary agent. When putty powder is mixed with water and applied to the wall, a chemical reaction occurs because new substances are formed. However, if the putty powder is scraped off the wall, ground into powder, and reused, it is not suitable because a new substance (calcium carbonate) has already formed. The main components of lime and calcium powder are Ca(OH)2, CaO, and a small amount of CaCO3. The reaction can be represented as: CaO + H2O = Ca(OH)2 — Ca(OH)2 + CO2 = CaCO3 ↓ + H2O. Under the action of water and carbon dioxide in the air, lime and calcium carbonate are formed. HPMC only assists in water retention and the better reaction of lime and calcium; it does not participate in any reactions itself.
