The best solution for surface curing of water-soluble coatings

With the increasingly stringent environmental requirements, almost all printing inks require water-soluble inks, and various coatings, varnishes, and other materials also require water-soluble materials. Due to the high specific heat capacity and heat of vaporization of water, evaporation of water solvents is much more difficult than traditional inks. Also, the chemical components of inks and coatings themselves are mostly organic polymers, which require rapid heating to promote polymerization reactions.

Infrared heating naturally has many advantages over traditional hot air heating, such as high energy density, good penetration, almost simultaneous drying of the inside and outside of the coating, and high speed.

Water soluble coatings are widely used in many fields, such as the surface treatment of wood, metal, glass, plastic, and other materials. How can we quickly and effectively cure the coating from the inside out without peeling, blistering, or cracking? Infrared heating has become the mainstream technology in the baking process, and is being adopted as an upgrade plan by more and more manufacturers.

1.Carbon infrared lamps can reduce energy consumption

The wavelength of the infrared radiator has a significant impact on paint drying. When irradiated with medium wave infrared rays, water quickly evaporates. This is because compared to short wave infrared radiation, medium wave infrared radiation has a better absorption effect, can be directly converted into heat, can more effectively dry water-based paint, and perform the same drying process with less energy.

2.Features of infrared ray used for surface curing of water-soluble coatings:

（1）Effective energy transmission through the use of optimal wavelengths has strong penetration and can be heated both internally and externally.

（2）Fast response time, high heat transfer ability, non-contact heat transfer, energy saving and consumption reduction.

Increasing production speed can also improve quality, while reducing scrap rates and saving costs.

Due to the above advantages, infrared ray is widely used in furniture, construction, household appliances and other industrial and civil goods industries, as well as in paint drying equipment and processes for powder spraying lines.

Medium wave and short wave infrared drying are both available options for drying water-based inks and coatings. In most cases, medium wave infrared is the best option. The ultra strong permeability of infrared rays can relieve heat to the inside of the coating, thereby achieving solidification from the inside out, solving the problem of surface dryness caused by traditional hot air heating. The application of infrared heating lamps to the surface curing of water-soluble coatings is an inevitable and optimal solution for comprehensive selection of environmental protection and economy.
