What are the characteristics of dry powder mortar?

-Literacy sticker: Many people often ask: What is the dry mortar produced by the dry mortar mixer, what is its use, and what is its manufacturing process? Today, Henan Hengxin Machinery will answer your questions. First of all, dry-mixed mortar is a green building material recognized by the government and society. At present, this technology is relatively mature. As its main additive, this material has been fully tested and applied in many projects, and its indexes are relatively stable. Through further exploration in production technology, all performance indexes will still be greatly improved and the cost will be further reduced. First, let's learn what dry mortar is. Dry mortar refers to a kind of granular or powdery material which is physically mixed by dried and screened aggregates (such as quartz sand), inorganic cementing materials (such as cement) and additives (such as polymers) in a certain proportion, transported to the construction site in the form of bags or bulk, and can be directly used after adding water and stirring. Also known as mortar dry powder, dry mixture and dry mixed powder, some building adhesives also belong to this category. Dry mortar plays the role of bonding, filling, protection and decoration in the construction industry, and is widely used in construction and decoration engineering. Before the emergence of dry powder mortar, most of the mortar used was mixed at the construction site. Due to the uncertain source of materials, deterioration during storage, large change in mixing ratio and poor mixing uniformity, the mortar mixed in site has unstable strength, poor impermeability and crack resistance and high shrinkage rate, which is the weak link in construction quality problems such as cracking, shelling, peeling and leakage. At the same time, the field preparation of mortar will inevitably lead to waste of resources and environmental pollution. Compared with the mortar mixed on site by traditional technology, dry powder mortar has the advantages of high product quality, high production efficiency, little environmental pollution and convenient civilized construction. Dry powder mortar mainly includes masonry mortar, plastering mortar, interface agent, tile adhesive, joint filler, putty for interior and exterior walls, waterproof mortar, floor mortar, self-leveling mortar, repair mortar, early strength mortar, powder coating, colored decorative mortar, thermal insulation mortar, non-shrinkage grouting, dry-mixed concrete, etc. As a building material, mortar has a history of thousands of years. However, the method of making mortar has been the mixing method on the workplace for thousands of years. With the development of building technology, the requirements for construction efficiency and building quality are constantly improving, and the shortcomings of on-site mixing mortar are gradually exposed. Dry powder mortar is a semi-finished mortar made of raw materials which are accurately mixed and stirred in the factory. The construction site can be used only by adding water and stirring. Dry powder mortar is widely used because of its variety. One of its greatest characteristics is that its thin layer plays the role of adhesion, decoration, protection and padding. For example, the mortar with bonding function mainly includes masonry mortar, wall and floor tile paste mortar, pointing mortar and anchoring mortar. Mortars with decorative repair effect mainly include plastering mortar, putty for interior and exterior walls, colored decorative mortar, etc. There are waterproof mortar, various anti-corrosion mortar, ground self-leveling mortar, wear-resistant mortar, thermal insulation mortar, sound-absorbing mortar, repair mortar, mildew-proof mortar, shielding mortar and so on. Therefore, its composition is complex, generally consisting of cementing materials, fillers, mineral admixtures, pigments, additives and other materials. Now, the production, popularization and application of building dry powder mortar in China have formed a new industry, creating a new growth point for housing industrialization. Dry mortar is generally made of industrial waste such as fly ash, and the recycling of waste brings great benefits to society. Because dry mortar is a revolution to traditional mortar, it is inevitably hindered by customary forces. Therefore, the government's decision-making and support are very important. With the concerted efforts of scientific research, production and construction, the dry-mixed mortar industry is booming. Ok, this is the general introduction of dry powder mortar. I believe everyone has understood the concept of dry powder mortar!
