Chemical additives are widely used in the papermaking process to produce certain paper products with certain special characteristics. The amount and type of chemical additives used are just as large and varied as different kinds of paper products. Accurately controlling the amount of these additives added is very important for the production of high-quality paper, but also to avoid wasting these expensive additives.
Industrial challenge
To obtain the corresponding characteristics, it is necessary to add a precise amount of additives at various stages in the paper production process. Dyes and pigments can be used to increase the color and shine. Spices can increase the odor of facial tissues, toilet paper and advertising paper. The addition of a bleaching agent, such as hydrogen peroxide, can increase the brightness of the recycled deinking slurry. Adhesives can increase water adhesion, while emulsifiers are used to ensure adequate mixing and distribution of the adhesive.
If the additive cannot be precisely controlled, the quality of the product will be very general, even if these expensive additives are continuously added too much in order to prevent an insufficient dose. Too much or too little dye or pigment can lead to unacceptable color tone deviations or product quality. Excessive spraying of expensive spices can increase waste and material costs. Uneven mixing of adhesives or deinking agents can result in too much foam. As a result, the finished product becomes a defective product, and remanufacturing will inevitably lead to an increase in material, operation, and maintenance costs.
Zenith's solution
Zenith precision metering pumps are pumps designed to precisely control the flow of these chemical additives. Zenith gear pumps provide accurate and repeatable pulseless flow. All parts are precision ground to ensure that the pump can still output accurate and repeatable high linearity flow rates in case of changing process conditions. Hardened stainless steel or tool steel materials have excellent corrosion and wear resistance. Therefore, the smooth, accurate flow of its output virtually eliminates overspray and uneven mixing.
How do you benefit
Product Quality - The accurate and repeatable, pulseless flow output of Zenith precision metering pumps ensures that the chemical additives are added in a smooth and appropriate amount, thus helping you to produce high quality paper products. When used with Zenith's ZeDrive speed controller, the pump speed accuracy can reach ±0.01% of the set point.
Cost Savings—The high efficiency and metering accuracy of Zenith precision metering pumps will allow you to continuously inject accurate quantities of additives and reduce the expense of these agents. The cost of eliminating waste and preventing duplicate production is also a direct saving method.
Zenith provides a full range of metering pump systems for the production of various papermaking products, such as coloring additives.
