Humidification engineering commonly used basic terms

Air is seen as being composed of pure dry air and water vapor. Relative Humidity: Humidity is defined as the amount of moisture in the air. This moisture must be in the form of water vapor. Visual water droplets that do not evaporate into water vapor will not affect the humidity. The term relative humidity refers to the ratio of the actual water content in a certain volume of air to the maximum saturated water content of the air at a certain temperature, expressed as a percentage (%), so: Ma Relative Humidity (RH) = ------- / t Mg Ma = content of water in the air Mg = maximum capacity of the air with water t = temperature ç„“: a thermodynamic property of the substance. It is defined as the sum of the volume and pressure of the material and the internal energy. Psychrometric, also called the airline diagram, is a thermodynamic mapping. Easy to get answers to various air-conditioning problems related to water vapor and temperature changes in a graphic way. Specific Temperature : Also known as specific humidity. The ratio of water vapor mass to dry air mass in wet air in kg/kg Dry bulb temperature: The dry bulb (DB) temperature of the air is the temperature measured by an ordinary dry-bulb thermometer. Wet bulb Temperature: The wet bulb (WB) temperature of the air is the temperature measured by the wet bulb thermometer. A wet-bulb thermometer is a thermometer that is wrapped in wet gauze on a common thermometer's bulb. Dew-poit: The temperature at which water vapor starts to condense when the temperature decreases. Dew condensation: The air is in a very humid state, that is, saturated air with a relative humidity of 100%. At this time, as soon as the temperature drops, water droplets can be seen. This phenomenon is called condensation. Latent heat: hidden on behalf of the potential, the temperature does not change the energy changes. Each material has a different latent heat.

ATP (NATIONAL STANDARD)

PRODUCT NAME: ATP Aluminum Dihydrogen Tripolyphosphate

PRODUCT TYPE: Anti-corrosion Pigment

PRODUCT APPEARANCE: White Powder

CHEMICAL CLASS:AlH2P3O10 Â· 2H2O

CAS No.: 13939-25-8

PRODUCT APPLICATION: Aluminum tripolyphosphate, as a new generation of white antirust pigment made by Xinsheng Chemical, is the ideal substitute of toxic antirust pigments containing lead or chrome. It turns out through practical applications and test results by over 100 well-known coating material producers or researching institutes at home and abroad since it came onto the market in 1986, that this product is superior to such antirust pigments as lead red, zinc chrome yellow and Zinc Phosphate in rust prevention and practicality.

Modified Aluminum Tripolyphosphate is suitable for production of water paint while Aluminum Tripolyphosphate is suitable for oil paint. ATP is used in high-temperature resistant paints, wear resistant brake pads and Wheel slices.
