The application of weathering steel plate etching is very wide, the common problems and reasons of etching pad printing steel plate

I. The photosensitive paste falls off or bursts during development A. The baking time is too long or the temperature is too high B. The sensitive paste is too thick or uneven C. The exposure time is insufficient D. The developer concentration is too high or the development time is too long E. Photosensitive paste has deteriorated F. Harmful light intrusion

2. The local pattern does not appear during development A. insufficient film blackness or film film surface inversion B. The drying time is too long or the temperature is too high C. The film is not tightly fitted to the photosensitive paste D. The exposure time is too long E. The photopaste coating is too thick

3. The photosensitive paste falls off during etching A. the photosensitive paste coating is too thin B. The drying plate is insufficient or the temperature is too low C. The etching water concentration is too high. Floral technology is a chemical process that creates various patterns on the surface of different metal products, such as sand, stripes, images, wood, leather and satin patterns. Different technical processes produce different patterns. It also includes spray pattern programs, such as: office document equipment, tape recorders, video recorders, cameras, car collision frames, mirrors, flower POTS, tableware and other surfaces are made of spray pattern.
