Sending paper. 1 Three indicator requirements for base paper: A. Flooding stretch rate. Refers to the size of paper fiber swelling after soaking in paper and before soaking. The water-soaked stretch rate of domestic paper is generally 2%-3%, while the good quality now meets the requirement of not more than 1.5%. Basis weight (gram weight). Refers to the weight of a square meter of paper. General paper weight is 80g/m2 and 100g/m2 C. Coverage. Simply speaking, it refers to the size of the paper covering the wall traces. The width of the commonly used base paper is 560mm. The gram weight is 100 grams. 2 If the product requires both sides to be flame-retardant, fireproof base paper is required. The basis weight of the fireproof base paper is 90 grams. (2) Coating. That is, the process of uniformly coating the paste on the surface of the base paper with a coating knife. (3) Drying (gelation). Drying uses a gas heater to dry (gel) the surface coating of the base paper through a hot air circulation system.The drying oven is divided into three zones. The temperature in each zone is controlled from low to high. The purpose is to ensure that the entire gelling process is stable and fully completed. (4) Cooling. Between gelling and printing, the hotter fabric is cooled and hardened by circulating cooling water through two cooling wheels. (5) Printing. That is, the use of printing wheels and circulating ink, different patterns using different printing wheels, the surface of the wallpaper printed with the required wallpaper pattern. The machine currently used by "Oja Wallpapers" is a six-plate printer, so it can be printed with up to six different pattern colors. (six) drying between the plates. It means that each pattern printed is dried by hot air heating before each plate is printed to avoid confusion between the front and back plates. (seven) soften. It refers to the use of a heating mantle to heat the harder wallpaper before embossing to soften it, facilitating embossing. (h) Embossing. It means that after the wallpaper is softened, the surface of the wallpaper is pressed with an embossing wheel to give it a corresponding texture effect. Embossing is divided into two types: flowers and flowers, depending on the pattern of the wallpaper. (9) Cooling. After soft embossing, it is cooled and hardened by a cooling wheel.
