  HPMC Cellulose  is a non-ionic hydroxypropyl methyl cellulose. It is commonly used as a water retaining agent in cement/mortar applications and is the most commonly used water retaining material. The production process of  HPMC  cellulose is the alkalization and etherification of cotton fibers to form a polysaccharide ether product. It is not charged by itself and the gel-like material in the charged ions does not participate in any reaction and has stable properties. hpmc cellulose is less expensive than other types of cellulose ethers and is widely used in dry mortar. The role of hydroxypropyl methyl cellulose 1. Thickening effect: HPMC cellulose can make the fresh mortar thicken and have a certain wet viscosity to prevent segregation. 2. Water retention effect: Water retention is also one of the most important properties, which helps to keep the free water in the mortar. It gives more time for the cementing material to hydrate after mortar construction. 3.Outgassing effect: HPMC c

  In the United States, meat consumption is at an all-time high according to the research and advisory firm, Rabobank projects. In 2018, meat consumption had reached more than 200 pounds per capita and has only been steadily growing. For restaurant owners, this means customers ordering meat and expecting it in a timely manner. To make speedy cutting possible, the proper commercial restaurant equipment is needed, which means finding a  Meat Dicing Machine  machine for sale. Quick Quality Results A commercial Meat Dicing Machine  is essential in a busy restaurant environment. While it can be tempting to try and cut everything by hand, during peak hours when speed is key, commercial Meat Dicing Machine s can really save the day. Whether you use it ahead of time to precut meat, or you use it as orders come in, you’re going to be greatly reducing the time it takes to get the meals out. This kind of quick service keeps customers happy and ensures that they are more likely to return in the fu

Most modern cars have brakes on all four wheels, operated by a hydraulic system. The brakes can be disc or drum type. The front brakes play a greater role in stopping the car than the rear brakes, because the brakes throw the weight of the car forward onto the front wheels. Therefore, many cars are equipped with disc brakes at the front, which are usually more efficient, and drum brakes at the rear. Full  disc brakes  are used on some expensive or high-performance cars, while full drum systems are used on older or smaller cars.   Hydraulic Braking Systems A hydraulic brake circuit has a fluid-filled master cylinder and slave cylinder connected by piping.   Master and Slave Cylinders The master cylinder transmits hydraulic pressure to the slave cylinder when the pedal is depressed.   When you depress the brake pedal, it depresses the piston in the master cylinder, forcing the fluid to flow down the pipe. Fluid flows to each wheel's slave cylinder and fills them, forcing the piston t

  Cold Rolled Steel: Cold rolled sheet  is a product made of hot rolled coil as raw material and rolled at room temperature below the recrystallization temperature. Mostly used in automobile manufacturing, electrical products, etc.    Hot Rolled Steel: By definition, steel ingots or billets are difficult to deform at room temperature and difficult to process. Generally, they are heated to 1100-1250 °C for rolling, This rolling process is called hot rolling.   Production Line Introduction   In Baosteel, there are three modern cold rolling mill plants producing automotive sheets, i.e. No.1 cold rolling mill plant (2030mm), No.3 cold rolling mill plant (1550mm) and 1800mm cold rolling mill plant built jointly with NSC and Arcelor.    Cold Rolled Steel Plate Product Category: Low carbon and ultralow carbon steel  Continuous cold rolled carbon structural steel plates and strips Continuous cold rolled high-strength bake hardening steel plates and strips Continuous cold rolled high-strength d

There are many types of glass, among which optical glass is one of them. The optical properties of quartz glass sheets have their own unique characteristics. IR. Because quartz glass has high temperature resistance, extremely small thermal expansion coefficient, good chemical stability, bubbles, stripes, uniformity, and birefringence comparable to general optical glass, it is a high-stability optical coefficient working in various harsh occasions. Essential optical material. It is widely used in lenses, prisms, etc. of optical instruments. Quartz glass sheet is a special industrial technical glass made of silica, which is a very good basic material.  Quartz glass plate   has a series of excellent physical and chemical properties, such as: 1. High temperature resistance. The softening point temperature of quartz glass is about 1730 ° C, it can be used for a long time at 1100 ° C, and the maximum use temperature in a short time can reach 1450 ° C. 2. Corrosion resistance. Except for hydr

    Velcorin , also known as dimethyl dicarbonate, is a preservative approved by the Ministry of Health and complies with the Food Sanitation Law of the People's Republic of China and the Food Additive Sanitation Management Measures. The molecular formula is C4H6O5, and the relative molecular mass is 134.09. The boiling point is 172 ° C, at room temperature, it is a slightly astringent colorless liquid, usually used in beverage cans. DMDC has a broad-spectrum antibacterial effect. Its main target microorganisms are yeasts (including Saccharomyces cerevisiae, Zygosaccharomyces ruckerii, Rhodotorula, Candida, Pichia, Toluobacillus, Torula, Endosporium, Klerkia, Hansenula, etc.). It also has a disinfecting effect on many other bacteria (such as Acetobacter pasteurianus, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, various lactobacilli, Pediococcus beer). DMDC has also been shown to kill E. coli 0157:H7. The antibacterial effect of DMDC is the result of inactivating

  Hot-dip galvanization  has been extensively used to prevent corrosion for 100 years. Hot-dip galvanized steel has a great lifespan. This effective form of galvanization provides 2 levels of protection : – Barrier protection – Cathodic protection   In Cathodic protection, Zinc protects the underlying material. If any part is scratched, Zinc will prolong its protection. Zinc can also function as a barrier slowing down the corrosion rate.   What is Hot Dip Galvanizing? Hot dip galvanizing is a process developed to prevent steel from corroding. Before the process can take place, the steel goes through a thorough chemical clean which removes all rust, oil and mill scale from the surface. When the cleaning solution has been rinsed off, the coating process can begin. The steel is dipped into a bath of molten zinc heated to around 450°C (860°F) before being left to cool in a quench tank. When the cooling process is complete, the zinc coating is then metallurgically bonded to the steel.   The
