Basic Principle and Application of UV Small Coater

introduction

In today's printing and coating fields, the application of UV (ultraviolet) technology has gradually become a disruptive change. As a specific application of UV technology, UV small coaters have gradually attracted the attention of the industry for their technical features and advantages. This article will provide an in-depth analysis of the technical principles and application fields of UV small coating machines, as well as their actual contributions to improving production efficiency and reducing energy consumption.

1. Basic principles

1.1 Overview of UV technology

UV technology is a technology that uses ultraviolet radiation to trigger chemical reactions. In the field of coating, UV light sources usually use mercury lamps, deuterium lamps, etc., which harden and solidify the coating by triggering the curing of photosensitive substances, giving it excellent performance.

1.2 Composition of small coater

UV small coating machine consists of base, coating roller, light curing device, conveying system, etc. The base provides stable support for the machine, the coating roller is used to spread the paint evenly, the light curing device is the key curing part, and the conveying system is responsible for moving the items to be coated to the appropriate location.

1.3 Workflow

The workflow of the UV small coater includes two main stages: coating and curing. In the coating stage, the coating roller spreads the paint evenly on the surface of the object to be treated; in the curing stage, the UV light source irradiates the surface of the paint, triggering the curing reaction of the photosensitive substance, and completing the curing of the coating.

2. Technical features

2.1 Efficient curing

Compared with traditional thermal curing technology, UV small coating machines have faster light curing speeds and can complete the curing process in a few seconds, greatly improving production efficiency.

2.2 Energy saving and environmental protection

UV curing does not require an external heating source, which avoids the problem of consuming a lot of energy in traditional thermal curing, achieves energy conservation, and reduces the impact on the environment.

2.3 Wide scope of application

The UV small coating machine is suitable for a variety of materials, including paper, plastic, metal, etc., and can be coated on the surfaces of items of different shapes, making it highly versatile.

2.4 High coating uniformity

The design of the coating roller and the precise adjustment of the coating control system enable the UV small coating machine to achieve precise control of the thickness of the coating layer and ensure the uniformity of the coating.

2.5 Suitable for special processes

Due to the particularity of UV technology, UV small coating machines can be used for some special processes, such as 3D coating, transparent coating, etc., expanding the application fields.
