Do You Know Screen Printing?

Polyester screen printing mesh wholesale  to share with you: Screen printing is also known as orifice plate printing. The formation of holes depends on the opening of the screen. The performance of the screen affects the quality of screen printing, such as the screen material, mesh number, opening degree, and aperture ratio, etc., have a great impact on the ink transfer of screen printing. Screen printing is commonly used: silk screen, nylon (polyurethane polyurethane) screen, polyester screen stainless steel screen and so on. Silk screen is also called silk screen. Silk screen is woven from natural silk. The earliest screen printing material. Advantages: strong water resistance, a certain moisture absorption, simple stretch net operation, and good binding with the photosensitive adhesive, Disadvantages: Poor abrasion resistance and chemical resistance, easy to age and brittle, stretched screen is low tension, low printing resistance, high cost. It is used less no...

Common faults and analysis of screen printing (Three)

Fourth, uneven ink The thickness of the ink film is uneven. There are various reasons. In terms of ink, the ink is poorly blended, or the normally blended ink is mixed into the ink skin. When printing, the solvent swells and softens due to the solvent. The mesh is blocked, which acts as a plate film and prevents the ink from passing through. In order to prevent this kind of trouble, the mixed ink (especially the old ink) should be filtered with a mesh before use before use. When reusing a pre-printed plate, the old ink attached to the plate frame must be completely removed. When storing the printing plate after printing, wash it thoroughly (including the squeegee). If the above requirements are followed, the uneven ink accident will not occur. If the tip of the front end of the scraper is damaged, a streak will appear along the moving direction of the scraper. Especially when printing transparent materials, there will be obvious uneven inking. Therefore, the front end of the scr...

Do You Know Nylon Mesh?

Nylon mesh is mainly made by P.P fiber textile molding. Acid and alkali resistance, good corrosion resistance. Low resistance, can be cleaned repeatedly, and the economy is extremely high. The captured long and short fibers and dust particles are easy to clean, and the filtration efficiency is not affected by cleaning. Good impact resistance. Material composition 1. The filter material is black nylon mesh made of PP material. 2, with acid and alkali resistance, corrosion resistance. 3. It can be cleaned repeatedly, and the filtration efficiency is not affected. 4. Generally designed as double-layer nylon mesh and iron wire support structure. 5. The outer frame can be designed as galvanized iron frame or aluminum frame. Nylon mesh supplier  introduces its uses: Nylon filters are used in refrigeration and air-conditioning products and equipment, air cleaners and air purification treatment equipment and engineering dust-proof primary filtering. Performance character...
