General Overview of Stone paper production line stone wall paper/notebook making machine
The paper is coated by blowing film,streamer or calender,and the coating solution is prepared according to the formula.the on the coating machine for coating production,this equipment adopts the method of rotary type reverse coating,through paper and reverse formed between coating roller,coating material feeding foller speed difference,realizes the uniformity and stability of coating adhesion on paper,again after oven to dry,repeat the same action to coating on paper back,finally the stability of the constant tension winding can be finished stone paper roll.
Main Components of Stone paper production line stone wall paper/notebook making machine
Step One: Granulating Line Stone paper production line stone wall paper/notebook making machine
In the high temperature and high pressure process environment, calcium carbonate powder, macromolecule materials and a variety of process auxiliaries are fully mixed and milled, and then extruded by screwing.
Step Two: Casting Line Stone paper production line stone wall paper/notebook making machine
The granules manufactured by the granulating machine are transported to the machine. After heating and strong pushing of the screw, the temperature of the raw material is raised and together with the molten PE material to be extruded into a "T" type die to form a three-layer composite sheet material, stretched by a casting roller and adjust the thickness of the product by controlling the speed, and then cooled and shaped by the cooling wheel set, and then flatten, visually inspect, thickness test,and static elimination, then cut off the ear materials and wind up the finished paper.
Step Three: Coating Line Stone paper production line stone wall paper/notebook making machine
The stone paper base paper produced by the casting method is coated, firstly, the coating liquid is prepared according to the formula and then coated and produced on a coater, and the device is coated by a rotary reverse method. By forming reverse velocity difference between paper surface and coating roll erand coating feeding roller, to achieve uniform coating and stable adhesion to the paper surface. After drying in an oven, repeat the same operation to coat the back side of the paper, and finally stabilize the constant tension. The finished stone paper roll can be obtained by winding up.
