Devices or measures that prevent the working medium from leaking out of the pump or prevent foreign matter or air from entering the interior of the pump are called seals and the medium to be sealed is usually liquid, gas or dust. Leakage caused by the main There are two aspects: First, there is a gap on the sealing surface. Second, the pressure difference exists on both sides of the seal site, eliminate or reduce any one factor can prevent or reduce leakage, to seal the purpose. Pump design...
According to the alumina production process, the production cost of alumina is roughly composed of the following: (1) Raw materials: bauxite, limestone, alkali (soda ash and caustic soda), etc.; (2) Auxiliary materials: steel balls, grease, conveyor belts, etc.; (3) Fuel and power costs: power consumption, steam consumption, water, heavy oil, coke, etc.; (4) Other costs: labor, manufacturing, management expenses. During this period, bauxite is the primary raw material and the primary source of...
[China Aluminum Industry Network] Aluminium anodic oxidation membranes are more often closed by boiling water and nickel acetate closure process. The disadvantage of these two commonly used closed processes is that after the oxide film is closed, the surface of the oxide film is prone to produce disagreeable white or gray powder, and the industry calls it a closed “cream” or “closed China”. Studies have shown that a variety of impurity ions blocking the treatment solution will promote the...
PropaLid is a BOPP film that has a strong seal to APET, CPET or PVC multilayer bags. Featuring peelable sealability, PropaLid has high barrier to water vapor, gas and fragrance. This film has a smooth surface and can be heat sealed on both sides. One side of the film can be printed, the other side can be peeled off the sealing coating, and has anti-fog function.
Abstract: Mooncake is a traditional food of the Chinese nation and is a must-have for the Mid-Autumn Festival. The sealing strength of the mooncake packaging heat seal is directly related to the sealing performance and bag breaking rate of the packaging and affects the quality of the mooncake in the circulation process. In this paper, Labthink XLW (M) intelligent electronic tensile testing machine moon cake packaging sealing strength during heat sealing for example, describes the principle of...
Selenium is the "king of cancer" in trace elements. Tricholoma contains more than 10 minutes of mineral elements such as selenium, calcium, magnesium and zinc. The absorption effect of human body is also very good. Every meal made with mushrooms should be 30 grams, and it is best to use fresh mushrooms. Mushrooms are also known as white mushrooms. They contain 8 kinds of essential amino acids and various vitamins, niacin and ascorbic acid. Mushroom fat content is only 4.4% of dry...
At present, the users of the domestic metallurgy, foundry, and machinery industries have the following types of instruments that can be used to analyze trace elements other than carbon and sulfur in metallic materials: 1. Spectrum Analyzer. The advantage is that multiple elements can be analyzed at a time with high precision. The disadvantage is that the price is too high, a set of hundreds of thousands to millions, so currently only a few large companies use. 2. Spectrophotometer. The...

Sealing is not one of the common faults of the continuous sealing machine. The sealing does not have three meanings: 1 The sealing position of the bag cannot be closed; 2 The bag mouth is sealed under the pressure of the sealing knife, but it is squeezed slightly or Tear-peeling and sealing cracked again; 3 When the peeling test was performed at the sealing area, half of the seals were firmly sealed and half separated. The sealing quality of the bag was still unacceptable because the contents...
