Papermaking chemicals: fungicides, Paper Making Chemical adhesive control agent, dryer stripping agent, defoamer, deodorant, blanket cleaning agent, dry cleaning agent.
Water treatment chemicals: reverse osmosis scale inhibitor, Paper Making Chemical reverse osmosis fungicide, scale and corrosion inhibitor, sterilization algicide, slime stripping agent.
Paper industry used in coatings and other batches, Paper Making Chemical intermittent operation of the preparation of chemical measurement. Using three shear beam sensor, Paper Making Chemical 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. In the instrument control began to feed the weighing, Paper Making Chemical 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, Paper Making Chemical all materials added, 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, Paper Making Chemical 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.
