Description

Technical Field

[0001] The utility model relates to the technical field of formaldehyde treatment, in particular to a formaldehyde treatment spray gun with an adjustable nozzle angle. Background Art

[0002] Formaldehyde is a colorless irritating gas with the chemical formula HCHO or CHO and a molecular weight of 30.03. It is also called formaldehyde and is irritating to the human eyes and nose. The relative density of the gas is 1.067 (air = 1), the liquid density is 0.815 g / cm³ (-20°C), the melting point is -92°C, and the boiling point is -19.5°C. It is easily soluble in water and ethanol. The concentration of the aqueous solution can reach up to 55%, generally 35%-40%, usually 37%, called formaldehyde water, commonly known as formalin. It has reducing properties, especially in alkaline solutions, where the reducing ability is stronger and can burn. The vapor forms an explosive mixture with air, with an explosion limit of 7%-73% ( volume), with a flash point of about 300°C. It can be prepared by dehydrogenation or oxidation of methanol under the catalysis of metals such as silver and copper, and can also be separated from the oxidation products of hydrocarbons. It can be used as a raw material for phenolic resins, urea-formaldehyde resins, vinylon, urotropine, pentaerythritol, dyes, pesticides and disinfectants. Industrial formaldehyde solution generally contains 37% formaldehyde and 15% methanol, which is used as an inhibitor. It has a boiling point of 101°C. A spray gun is needed in the treatment of formaldehyde, but the existing spray guns do not have the function of adjusting the angle. People often hold the spray gun in their hands to work, and the corners cannot be effectively cleaned in a narrow position. Therefore, it is necessary to design a formaldehyde treatment spray gun with an adjustable nozzle angle. Utility Model Content
