(1) Key points of start-up operation of the drying section of the paper machine:1. Check whether there are any abnormal objects in each group of drying nets, whether there are sundries inside and outside the machine, and whether there is paper wrapped around the shaft head.
The paper machine is a combined machine composed of a series of ancillary equipment, divided into two parts, the wet part and the dry part. The wet part includes the sizing flow system, wire and pressing parts, and the dry part includes drying, calendering and coiling parts.
Before starting the machine, use hand rotation to check whether the moving parts are jammed or not, and whether the connections are tight, and then they can be idle. When operating, pay attention to whether the equipment has other abnormal phenomena.
The paper machine production line is composed of many ancillary equipment, and there are many ancillary equipment in it. Among them, the pulping equipment is one of the important supporting equipment, and it occupies an important place in the paper machine production line.
High-concentration beating can be achieved through high-concentration disc refiner or other high-concentration fine grinding equipment. High-concentration beating than low-concentration beating can significantly improve the properties of paper, such as tensile strength, tear resistance, flexural resistance, fracture resistance and elongation.
