Water writing paper is divided into two types: physical reaction and chemical reaction. The surface of physical reaction type water writing paper is not coated with any chemical raw materials, and the paper is dark green in appearance. The surface has the rough feeling similar to Xuan paper naturally formed by pulp fiber, and has the characteristics of water seepage and moistening. According to the principle of spectral change after meeting water, when writing on paper with a brush dipped in water, the handwriting will show ink color.
The surface of chemical reaction type water writing paper is coated with chemicals, and the paper appearance is gray white, and the surface is smooth. There are special chemicals that can change color when meeting water on the base paper. When the brush is dipped in water to write on the paper, the handwriting will appear black.
The main requirements of water writing paper are good dimensional stability, high tensile strength and tear strength. It can be used repeatedly.
Water writing paper is a kind of domestic advanced, popular, water instead of ink, reusable durable paper. The utility model has the advantages of convenient carrying, simple use and water consumption. Because the water writing paper can be used for thousands of times repeatedly, one water writing paper can save thousands of ordinary paper, which is both saving and saving paper.
[characteristics comparison]
The physical reaction type of water writing paper has the effect of rice paper, strong water permeability, and will not halo and dye each other. The handwriting will disappear after 15-20 minutes.
The chemical reaction type water writing paper has smooth surface, weak water permeability, fast color change when writing, and the handwriting disappears after 3-5 minutes.
Proper amount of water can make the surface sticky; Early adhesion, strong wet adhesion and good permanent adhesion; The bonding water and curing condition are not affected by hot and cold climate; Good tensile strength, high tensile strength, not easy to break; Excellent raw materials are selected, non-toxic and pollution-free; If you want to remove the adhesive tape on the surface of the adhesive, you can use a sanding machine or emery cloth to remove the adhesive tape without leaving traces.
Specifications
12mm * 500 yards, 16mm * 500 yards, etc. the width and length can also be customized by the demander (divided into perforated tape and non perforated tape).
purpose
It is suitable for splicing and joining of veneer and board. It is mainly used in furniture, wooden door and other industries for panel patching, plywood and bending wood industries for repairing medium plate, veneer and so on.
