It is suitable to use the inner light knife to scrape the cloth indoors, and the external light knife can be used to scrape the cloth indoors and outdoors. In addition, the inner light knife squeegee is also called a net-free knife squeegee, which has good light transmittance, and the outer light knife squeegee is opaque. Introduction: Knife scraping cloth is a chemical synthetic material, and its thickness is thicker than ordinary lamp cloth. The front of the scraper cloth is flexible and smooth, the back is rough, and the granularity is thick and uneven. Knife scraping cloth is divided into high-gloss surface and matte surface, mainly because of the different scope of application. Finished product features: (1) High strength, good ductility and flexibility. This unique property makes this material widely used in the large-format, high-end fine commodity market. (2) The surface is smooth and has strong ink absorption. The chemical properties of the material determine that it has strong ink adsorption, and can adhere with high strength under oily or water-based ink conditions. (3) Stable physical and chemical properties, mainly in anti-oxidation, acid and alkali resistance and severe cold resistance. Uses: Knife scraping cloth is generally used for coating canopies, light boxes, background boards, wide advertising paintings in public places, etc.
