Coating coating on the surface of the substrate, from liquid or loose solid powder state into a dense and complete solid film process, known as coating or coating drying or curing Common curing methods for coatings
1. Dry naturally
Under natural conditions, the use of air convection to make solvent evaporation, oxidation polymerization or reaction with curing agent into a film, suitable for volatile coatings, air-dry coatings and curing agent curing coatings and other self-drying coatings, drying quality is greatly affected by environmental conditions.
2. The drying
According to the drying temperature can be divided into low temperature drying (less than 100°C, mainly for self-drying coating or poor heat resistance of the material surface coating drying).Medium temperature drying
1.1 methods of hot air convection: and several methods of hot air convection and radiation.Hot air convection heating uniform, high temperature control, suitable for high-quality coating, not affected by the workpiece shape and structure complexity, but the rate of temperature rise is slow, low thermal efficiency, large equipment, coating easy to bubble, wrinkle.The heat sources used are steam, electricity, diesel, gas, liquefied gas and natural gas.
1.2 thermal far infrared radiation mode: thermal radiation heating usually USES infrared ray to heat the substrate and paint at the same time, with fast heating rate, high thermal efficiency, small floor area, but the temperature is not uniform.
1.3 combination mode of convection and radiation of hot air: generally, convection is followed by radiation. The workpiece is heated by taking advantage of the advantages of fast radiation heating, and then hot air convection is used for heat preservation to ensure the drying quality.
3. Radiation curing
Using electron beam, UV irradiation electron beam curing coating and UV coating, has the advantages of short time, room temperature curing, the device price is relatively low.But irradiation has blind spot, only suitable for simple shape workpiece, irradiation distance control is strict.
