[Powder in life] Maybe you don’t know, your whole life is closely related to powder
When it comes to powder, many people think that it is an unreachable industry, far away from their own lives, and seems to have no intersection with ordinary people’s lives. As everyone knows, powder is full of our daily life. From birth, powder has been with everyone’s life.
When you are a baby waiting to be fed, powdered milk is almost all of your life, and the processing technology of powdered milk involves dry processing. All raw materials such as base powder (milk powder, skimmed milk powder, whey powder, etc.) and various nutrient ingredients are weighed, sterilized and mixed in the required proportions in a dry state, and finally packaged and shipped to become the final product to millions of households. The dry process has a short production cycle, easy addition of nutrients, and small loss of nutrients; because the production can use milk-based raw materials produced in advance, it is not controlled by factors such as milk production season and milk production.
As the most important raw material for diapers, non-woven fabrics are composed of directional or random fibers, which are moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and can be used. Features such as recycling. In the non-woven fabric production process, calcium carbonate powder is added in order to increase the weight or hardness of the fabric. Calcium carbonate powder generally chooses calcite with good fluidity, low oil absorption, high whiteness, and less impurities as the master batch powder.
When your parents start to add supplementary food for you, the seasonings in the dishes on the table are inseparable from powder. In China, wheat and rice are the main raw materials for making staple foods, and their quality has a significant impact on the processing and eating quality of traditional noodles such as noodles, steamed buns, and rice. Airflow classification technology has made outstanding contributions to its quality improvement. Airflow classification is the use of different particle size particles in the gas medium (usually air), the combined effects of gas drag, own gravity, inertial force, and centrifugal force are different. The coarse particles settle and the fine particles are carried away, thereby separating the coarse and fine particles.
After air classification, the different components of wheat flour exhibit different physical and chemical properties and rheological properties, enrich the nutrients in wheat flour, and provide special wheat flour, flour additives, flour improvers and functional flour made from colored wheat. Way.
When you start to babble and walk into kindergartens, elementary schools, junior high schools, high schools, and universities, the pencil becomes your longest companion. The raw materials of modern pencils are mainly graphite powder and white clay powder. Graphite powder is an important non-metallic material. Graphite powder is widely used in petroleum, chemical, lubrication, sealing, conductive and other industrial fields. The raw ore after blasting is sent to the rock breaker through the mine cart to be crushed, and then the ball mill is used for flotation and selection. The dry material is sent to the drying workshop, dried and then bagged, that is, ordinary graphite powder, and the average carbon content of the product is 90%.
When you graduate to work, coffee has become the standard to witness every night of your struggle. The roasted coffee beans are ground to form fine powders. This process accelerates the release of CO2 gas and volatile aromas in the cooked beans, improves the extraction efficiency of soluble flavor substances, and affects the flavor and mouthfeel of the finished product. The size of coffee particles is related to the extraction of soluble and volatile substances, and the size of the particles depends on the characteristics of the relevant equipment and operating technology used when grinding coffee.
Grinding degree refers to the ratio of the increase in the total surface area of coffee beans after grinding into particles to the surface area of the original coffee beans. The greater the grinding degree, the smaller the coffee particles, and the easier it is to extract the bitter substances (caffeine, trigonelline, etc.) in the coffee, and the more significant the bitterness of the coffee; on the contrary, the more sour.
When you finally have savings, with your own house and car, powder is also inseparable from all aspects of new house decoration. The most representative and most important building material is putty. Putty is generally made of base materials, fillers, It is composed of water and additives. The filler mainly plays a filling role. Commonly used are calcium carbonate, talcum powder and quartz sand. Calcium carbonate is the main filler in the putty, and a small amount of lithopone is added to increase the viscosity and prevent the paint from loosening. At the same time, precipitate calcium carbonate is appropriately added to facilitate drying and polishing.
With the popularity of new energy vehicles today, lightweight has gradually become a new trend in automobile production, and “plastics instead of steel” has successfully emerged from many solutions. However, ordinary plastics cannot meet the performance requirements of automotive applications. At this time, it is necessary to use powder to modify the plastics. Mineral-reinforced and toughened plastics are one of the most common ways of modification. Commonly used mineral powders include calcium carbonate, talc, wollastonite, mica powder, glass beads and so on.
When you retire gloriously and start to learn about maintenance, medicines and nutrients are always protecting your body. Did you know that these common medicines are also made of powder? Montmorillonite powder for adults and children with acute and chronic diarrhea. The main ingredient is montmorillonite, which is a layered mineral composed of extremely fine-grained hydrous aluminosilicate; used to treat acute itching such as urticaria and rash Calamine lotion for skin diseases, its main ingredients are calamine (a carbonate mineral calcite family smithsonite, mainly containing zinc carbonate), zinc oxide; bezoar detoxification tablets for heat-clearing and detoxification, its main component is artificial bezoar , Realgar, gypsum, rhubarb, scutellaria, platycodon, borneol, licorice, realgar, is the common name of tetraarsenic tetrasulfide (As4S4), is a sulfur and arsenic ore, gypsum is a monoclinic mineral, is the main chemical component It is a hydrate of calcium sulfate (CaSO4).
ALPA is a well-known provider of ultra-fine powder ending solutions in China, focusing on ultra-fine ultra-pure pulverization and classification research, powder shape control and selective pulverization, split surface modification, and system integration of split engineering equipment. solution. The areas involved include non-metallic minerals, medicine, food, plastic products, high-tech materials, plastics, ceramics, etc., and have summarized and counted the ultra-fine grinding and classification solutions for tens of thousands of materials for more than 3000 companies at home and abroad.
