Research and development, production of UV ink problems

In the modern industrial field, UV ink is more and more widely used, it has excellent weather resistance, bright color and good printing effect. The production and manufacturing of UV ink requires the synergy of a variety of technologies, materials and equipment, which can be said to be a highly comprehensive technology. This article will introduce in detail the professional knowledge and technical concept required for the development and production of UV ink.

First, the basic properties of UV gloss ink

UV ink refers to a special ink used for printing, which is a system composed of monomers, prepolymers, initiators, diluents and auxiliaries. Methylene acrylate, methacrylate, etc., is a monomer that polymerizes under ultraviolet irradiation to form a polymer system with strength and hardness, so as to complete the purpose of ink curing.

UV ink is composed of high polymer and low molecular monomer, high polymer is a material with printing properties, and low molecular monomer is a key component to complete the ink curing. UV ink is characterized by its rich aromatic structure, which can provide the electron transfer properties and better physical and chemical properties required for ink coating.

Second, the development of UV ink

The development of UV ink requires a variety of technologies and knowledge. The research and development process includes the selection of monomer, the ratio, the optimization of reaction conditions, the selection of diluent, processing AIDS, and the screening of curing agent. First of all, it is necessary to select monomers according to the requirements of the use of ink, and determine the basic system and curing properties of UV ink. In the matching process, it is necessary to ratio and balance various performance indicators according to the chemical structure, reaction characteristics and functions of the monomer. The optimization of reaction conditions mainly includes light source, irradiation concentration, irradiation time and so on. Diluents and processing AIDS can change the fluidity, viscosity and other properties of the ink, and curing agents can change the hardness of the ink, wear resistance and other properties. It is necessary to find an excellent combination in the adjustment and balance of the above parameters to determine the required ink formula.

In the research and development of ink, it is necessary to carry out chemical analysis, physical property testing, application performance testing and other work. Chemical analysis is to prevent the appearance of certain substances in the ink that should not be present, or there is no correct and reasonable chemical substance in the formula. Physical properties test for ink, such as gloss, abrasion resistance, chemical resistance and other properties evaluation. The application performance test is to test the printing effect, drying time and gloss, wear resistance and chemical resistance of the ink in a real environment.

Third, the production of UV ink

The production of UV ink is the process of transforming research ideas into industrial production. Through the needs of the printing industry and the quality requirements of products, the development of UV ink processing standards, production procedures and equipment specifications and selection. Commonly used processing technologies include centrifugal separation, ultrafiltration, filtration, drying, grinding and so on.

The production process needs to strictly control the parameters to ensure the ink quality and cost stability. In the rapidly developing UV ink market, product quality, quality stability and delivery time are more and more concerned by customers, therefore, in the production process also need to attach great importance to quality management. For the procurement, use and management of raw materials, the indicators are required to meet international or industry standards, and at the same time, it is necessary to pass strict testing, inspection and other links for acceptance and confirmation. In the production process, it is also necessary to strictly control the storage and processing environment of materials, master the corresponding technical requirements, operating specifications and quality inspection standards, etc., to ensure the quality and long-term stability of UV ink.

The research and development and production of UV ink is a complex work that requires the perfect collaboration of a variety of technologies, materials and equipment. Therefore, it is necessary to continuously strengthen technological innovation, improve and optimize management, and continuously enhance core competitiveness in order to stabilize the advantage in the industry and meet the needs of the market and customer requirements.
