Paper Making Chemical More Common
Aug 07, 2017

With the increasing complexity of pulp and paper equipment worldwide, Paper Making Chemical the use of additives to solve the problem of papermaking industry production becomes more common, papermaking chemicals gradually become fiber raw materials and minerals after the third important pulp and paper raw materials.

At present, the application of paper chemicals related to pulp and paper technology in all aspects of the product range, the wide range of applications, Paper Making Chemical the impact of large technology, attention to the high degree of unprecedented.

Into the 21st century, pulp and paper equipment booming, new technology and new equipment after another. Technological advances not only improve and improve the production efficiency and quality of paper, Paper Making Chemical but also put forward higher requirements for chemical applications, paper chemicals market prospects.

Paper industry used in coatings and other batches, Paper Making Chemical intermittent operation of the preparation of chemical measurement. Using three shear beam sensor, dedicated connection module and a balanced circuit board with a dedicated junction box composed of field weighing station. In order to ensure the stability of the weighing tank, the limit device will be installed. Like paint preparation often used multi-material a scale measurement, feeding weighing using "cumulative method." The material of each component is pre-set according to the formula. Paper Making Chemical In the instrument control began to feed the weighing, to the formula set value, the first feeding end, the instrument clear and back to zero, ready to feed the next kind of material weighing, all materials added, Paper Making Chemical the instrument Returns the "total weight" status.

The whole process is under PLC or DCS control. Paper Making Chemical The scale of the electronic scale for the paper industry is ± 2 kg, so it can only be used for the measurement of large component materials in the formula. The small component material is measured by means of higher precision equipment such as flowmeter and metering pump.

The following should be noted when installing and using metering pumps:

(1) the plane of the sensor must be kept horizontal, Paper Making Chemical the roughness within the specified range; between the sensor elevation error within the specified range;

(2) the sensor can not bear the lateral force or super [Received date: 2011-08-04] set, installed to prohibit oblique hanging, twisted, the selected hanging point should be kept level; Paper Making Chemical screw to withstand the sensor arm, should be vertical ; Should be installed limit device;

(3) the sensor can not be damp, due to moisture will make the sensor insulation worse, resulting in internal short circuit, performance degradation. In the open air, where the humidity is large, should be installed in the sensor moisture cover;

(4) to prevent the sensor electric breakdown, Paper Making Chemical after the installation of the sensor with a soft connection wire will scale body and the device active body shorted to avoid the scale body on the welding work.

The following should be noted when installing and using metering pumps:

(1) the pump should be installed in a special spare concrete foundation or cast iron platform, Paper Making Chemical corrected with anchor bolts, concrete foundation should be higher than the ground 50 ~ 100mm above;

(2) suction and discharge diameter should not be less than the import and export diameter, Paper Making Chemical suction pipe should be shortened;

(3) exports higher than imports, to avoid siphoning phenomenon;

(4) pump head and injection valve required vertical installation;

(5) attached to the hand can be tightened by hand, Paper Making Chemical do not use the tool; thread does not use raw material belt;

(6) The power supply voltage is stable and grounded.
