For many years, brush coater is the only form of coater. But with the development of paper machine coater, has invented many new coater, one of the main roller automatic coater. It is covered by a metal roller coating mixture spread on the paper surface. Generally suitable for paper machine coating, but also can be used for ordinary coating. This coater generally consists of two types: flat roller coater and concave roller coater. Compared with the coater mixture used by brush coater, roller coater can use the coater mixture with higher viscosity. Denatured starch is especially suitable for roll - coated adhesive. A roll coating mixture containing 55-70% solids can be produced with a low viscosity modified starch.
In addition to this one, there are many kinds of can be through the high-speed roller automatic coater operation, increasing the understanding of the basic knowledge of coating, the knowledge obtained from roller coater, for the study of other coating processing methods are also of great value.
