RDP chemical for Russia
RDP chemical for Russia: The Key to Enhanced Construction
The construction industry has been flourishing in Russia and other countries, making it a promising market for various chemicals that aim to enhance construction quality. Among these, the RDP chemical holds a significant place that is widely used in the construction industry for enhancing the quality of walls, screeds, plasters, and other concrete surfaces. The versatile chemical is on the rise because of its broad range of uses, sustainable nature and cost-effectiveness.
RDP Chemicals are an important ingredient in the construction industry due to their high-performance functionalities. They work as additives, augment the physical as well as mechanical properties of the construction materials, and reduce the water absorption rate of structures. RDP Chemical bonds physically and chemically with multiple surfaces and helps in their long-term durability and sturdiness.
One of the most striking features of RDP Chemical is its sustainability. The chemical is environmentally friendly, non-toxic, and doesn't release any harmful material during use. Therefore, it is widely accepted by environmental regulations, and also, it provides a safer environment for construction workers.
Furthermore, RDP Chemical is economical compared to various traditional additives used in the construction industry. It reduces shrinkage of construction materials, increases adhesion, and has a long service life – it can maintain the quality of surfaces for years.
Russia and other countries such as Palestine, Morocco, Philippines, Bosnia and Herzegovina, are all experiencing significant growth in their construction industry, resulting in an increased demand for RDP Chemical. The chemical is a go-to solution for various construction needs and is highly recommended by construction experts.
In conclusion, RDP Chemical is a game-changer in the construction industry, providing sustainable, cost-effective, and high-performance solutions. Its popularity in the Russian and other construction industries is rising, and it is a key solution for enhancing the quality of construction materials in these countries. Therefore, if you are in the construction industry in Russia, Palestine, Morocco, Philippines, Bosnia and Herzegovina, it's time to switch to RDP Chemical: the perfect solution for upgrading your business.

What is the recommended viscosity of Hydroxypropyl Methylcellulose (HPMC)?
For putty applications, a lower viscosity of 100,000 is sufficient, and good water retention is important. For mortar applications, higher viscosity of 150,000 is preferred. For adhesive applications, a high-viscosity, quick-dissolving product is required.
How to choose the appropriate hydroxypropyl methylcellulose (HPMC) for different applications?
HPMC can be divided into two types: instant soluble and heat soluble. Instant soluble HPMC quickly disperses in cold water, disappearing in the water. At this stage, the liquid does not have viscosity because HPMC is only dispersed in the water and not completely dissolved. After about 2 minutes, the viscosity of the liquid gradually increases, forming a transparent and viscous colloidal solution. Heat soluble HPMC tends to agglomerate in cold water but can rapidly disperse in hot water, disappearing in it. As the temperature decreases to a certain point, viscosity slowly appears until a transparent and viscous colloidal solution is formed. Heat soluble HPMC can only be used in putty powder and mortar, as it tends to agglomerate in liquid adhesives and coatings and cannot be used effectively. Instant soluble HPMC has a wider range of applications and can be used in putty powder, mortar, liquid adhesives, and coatings without any restrictions.
How many types does 2-Hydroxypropyl methylcellulose (HPMC) have, and what are the differences in their applications?
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.
How many types does 2-Hydroxypropyl methylcellulose (HPMC) have, and what are the differences in their applications?
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.
