Consumables for screen printing equipment

Consumables: scraping glue, ink, boiling oil, screen printing, etc. Let me introduce them one by one.

Scraping glue: Scraping glue is the glue strip used in the process of screen printing, also known as scraping glue. Most of them are made of PU. According to the characteristics of screen printing substrate, the precision requirements of printed patterns and different printing methods, scrapers with different hardness and different cross-sectional shapes can be selected. The hardness of scraping glue refers to the hardness of its surface. Shore hardness is commonly used, including 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees and 85 degrees. Cross-sectional shapes generally have right angles, acute angles and circular arcs.

Ink: Ink is an important material for packaging material printing, and patterns and characters are displayed on the substrate through printing. Ink includes main components and auxiliary components, which are evenly mixed and repeatedly rolled to form viscous colloidal fluid. It consists of pigments, adhesives and additives. Used for printing books and periodicals, packaging and decoration, architectural decoration, etc. With the increase of social demand, the variety and output of ink also expand and increase accordingly.

Oil boiling water: oil boiling water, also known as diluent, can adjust the viscosity of ink and improve printability. In addition, it can dilute coloring power, increase printing area and significantly reduce costs. Oil boiling water is a solvent for diluting ink or paint. When the ink is dry, it will affect the effect of the pattern, especially the smoothness and brightness.

Screen printing is also called screen printing, screen printing and screen printing. Optical tools for photographic plate making. A commonly used screen for letterpress and planographic plate making is to use two pieces of optical glass, which are engraved with black and white parallel lines with the same width and cross each other at 90 degrees to form a grid. The incident light is divided in front of the negative, and due to diffraction, dots of different sizes are formed on the negative to show the level of the picture. The mesh structure has grid, circle and chain, and the general specification is 20-80 lines/cm. The commonly used screen for intaglio plate making is made of glass or film, and the surface has white thin lines crossing to form a square. When making a plate, the film at the white line becomes hard after exposure, so it will not be corroded. As a support for protecting the layout, the general specification is 60- 100 lines /cm. There is also a film screen with halo, which is called contact screen when it is used in contact with photosensitive film and negative film. English term: screen.

Products mainly used for screen printing are collectively referred to as: screen printing equipment; As you can see, Pinghu Yixing Silk Screen Printing Equipment in Longgang District, Shenzhen is a shop that mainly produces and sells silk screen printing equipment.
