rate of addition of titanium dioxide anatase control

titanium dioxide anatase opacity to meet the objectives and to minimize cost, requires precise control of the addition rate of titanium dioxide. Mills are moving online monitoring using feedback control loop development. Titanium dioxide is  Plastic impact modifier controlled by the flow line opacity. Ingredients for a very fast response time to changes in the lower opacity fluctuations, thus reducing the amount of the pigment used per ton of paper. Problems which need to be Calcium stearate  considered online product opacity and opacity variations. You can usually correct this bias, or adjust the target line. Other mills there is a non-normal operation of the test strip of opaque elements, and the corresponding adjustment of the flow of paint, this technique is very effective.

titanium dioxide anatase accurate calibration of flow measurement equipment is critical. There have been reports that a paper mill, on a machine using an excessive amount of titanium dioxide in the entire system does not stearic acid  bring any other changes. But the survey found a flowmeter failure. Therefore, we must fully consider the use of time flowmeter and ensure the accuracy of the validation. Currently in commonly used in the paper industry is a magnetic flow meter and density / mass flowmeter.
Another key aspect is the addition rate of the flow control valve, the size must be selected to suit the required flow rate. The valve should operate within the range of nearly 50%. If the valve is opened too big or too small, will affect the control accuracy. Control valve seat require regular maintenance, because they will wear. When the control valve is closed if the flow is still present, it shows the seat definitely worn out.

titanium dioxide anatase could trigger an environmental crisis

Nano-titanium dioxide, also known as titanium dioxide. Because of the high refractive index, superior absorption ability and excellent UV sterilization, deodorization, and antifouling properties, titanium dioxide anatase is often regarded as a photocatalyst and environmentally friendly additives and a plurality  PVC stabilizer worldwide Widely used. As for skin care products, food, white paint and other consumer goods and household production, the annual production capacity of up to millions of tons, and showed a rising trend.
Proved by experiments, titanium dioxide anatase atmosphere rich in nitrogen and oxygen can be formed on the surface of nano titanium dioxide photocatalytic reaction by nitrates and combined to form a mechanism to clarify the Metal stearate  theoretical calculation and analysis of nitrate. Excessive nitrates discharged into water bodies, the body will produce toxic, such as lead children “blue baby syndrome” can cause eutrophication and cyanobacteria outbreak, resulting in environmental pollution problems.
Photocatalytic formation of nitrate found in the photocatalytic reaction, remind people may have underestimated the potential environmental risks of extensive use of titanium dioxide. The chemical reaction on the one hand may Stearates  exacerbate the increasingly serious problem of nitrogen pollution, but it also provides a mild conditions and low cost method of producing nitrates new.

The main structure of introduced organic pigments
