How to correctly operate the double disc refiner (I) Firstly： The top priority for startup, running, and maintenance is safety! Secondly： How to use the double disc refiner correctly? Let’s learn about it through the following short video: Thirdly: Install the refiner discs correctly Fourthly: disc refiner and zeroing Notice: The two hexagon socket bolts need to be…
Tissue paper is a lightweight paper, or a crepe paper, which can be made from recycled paper pulp . among other materials. It is mainly defined by its softness and fabric like feel. The tissue paper manufacturing process only varies slightly from that of other papers. It goes through the same underlying pulping, pressing and…

The recycled cartons are compressed and packed into cubes for the convenience of transportation, and then sent to recycling plants. The cardboard boxes are recycled and made into recycled paper. Generally Speaking, the treatment of waste paper includes four stages of pulping, screening, cleaning and thickening. However, due to the variety of impurities contained in waste paper, especially…
When we are talking about producing high quality tissue paper, most of the people will firstly have the “crescent-shaped forming technology” in their minds, well, it is saying stock preparation contributes 70% to the quality of the final product and paper making contributes the remaining 30%, a good forming of the fiber mat on the…
Screening efficiency impact factors Reject rate Basket type Slots gap Bar depth/angel Velocity Open area Rotor Pulse Pressure pulse forces the stock through the screen Vacuum pulse draws disturbing components away from the screen surface, removing them from the screen area The higher the rotor peripheral speed, the greater the pressure pulse The higher the…
Valve Brief Introduction: The valve is a mechanical device that controls the flow, flow direction, pressure, temperature, etc. of the flowing fluid medium. The valve is a basic component in the pipeline system. Valve pipe fittings, like pumps in technology, are often discussed as a separate category. Gas switch and faucet are the simplest valves.…
1. When the ash content of the paper is too low, the degree of beating can be increased to seal the paper to increase the filler retention. 2. The paper is floating on the cylinder surface because the adhesion between the paper sheet and the cylinder surface is not enough, and the beating degree can…
i-CTMP Pulping principle: The cleaned raw material is first softened at high temperature and then filamentized at high temperature with a filamentizer. The whole process needs to be performed at high temperatures to soften the fibers and reduce the bonding force between them, avoiding or reducing the possible damage to the fibers during high temperature filamentation.…
CTMP Pulping principle： Wood chips are impregnated with selected chemicals at a certain temperature to soften and swell the amorphous areas of lignin, hemicellulose and cellulose in wood. When the temperature reaches the“glassy”conversion point of lignin , the fibers are separated from the wood matrix by the compression pulse action of the fluted disc and other mechanical actions…
