The term coated applied to any paper or board to which has been applied a coating of any character or substance. In the present case of coating the printing grades of paper and boards, the primary objects in the coating operation is to produce a sheet with an even, semi-absorbent surface for printing. This is effected by covering the fibers on the surface of the paper and filling the hollows between them with finely divided mineral matter, mixed with an adhesive or "size". When such paper is calendered, there results a smooth even surface, which reproduces the half tone dots of the printing plate much more faithfully than any plain paper.
Air Knife Coater : The lab coater is designed to make it possible to obtain small coated paper samples. Different types of coating mixtures can be used to obtain the coated paper samples. The coating result corresponds well to that obtained by production airknife coaters.
The coater consists of a welded squire shaped frame of the size length 24", width 14" and height 12". The frame contains a transformer , a blower with a manometer 8-800 mm water pressure and a reversible motor.
On the front are the controls. When the main switch is in position 1, the table can be moved. In position 2, the blower for the air knife will operate. Beside the main switch is the switch for the reversible motor that moves the table with the sample forward and backwards. A movement to the right moves the table to the right and the monometer is then visible. By switching on to the left the table goes back. On the right of the main switch is the regulating transformer for the blower. The air pressure is read, on the monometer. Across the table over the whole width is the air knife.
It is possible to adjust the opening of the slit by the screws along the length of the airknife and is generally kept at 0.04-0.05 cm.
Test the coated sheets and uncoated base paper sheets for the following and compare the results and report :
Dennison standard paper testing waxes are designed for use by paper and coated paper manufacturers, printers, lithographers, and other concerned with the development, inspection and control of paper for coating and printing purposes.
The use of these waxes I described by the Technical association of the pulp & paper industry in relation to the surface strength measurement of paper products. Method T456-SU-65 published by the Association gives their latest approved method for this measurement. The use of these waxes is also described by the American society for testing and Materials in their method D2482-66T.
The wax test is applicable to coated and uncoated papers and is formulated to evaluate the surface strength of paper or its resistance to picking. This test may be conducted to determine the degree of sizing in the coating in relation to the required press conditions, to estimate the ease with which a coating may be removed or “picked’ from the bodystock, and the tendency of the bodystock to split or the printing process. It is used in a similar manner for evaluating uncoated papers and other surfaces.
The series of waxes have graded adhesive powers. They run from 2A, which has the least adhesive strength, and increase by small graduated amounts to 23A which has the greatest adhesive strength. Hence there is an increase in the degree of adhesion to surface fibres or coating coincidental with the increase in wax numbers.
The complete series consists of 18 waxes, Nos. 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A, 13A, 14A, 16A, 18A, 20A, 23A, and is available as a set in a cabinet, with an alcohol lamp, instructions, and accessories.
The instrument has a castled stand and having two parallel, plane circular faces between which the test piece is placed for measurement. One of the faces (the anvil).In the measuring spindle there is a stationary lower measuring area of 200 mm2. The movable measuring area is fixed on a bar, which also supports the dead weight load. The pressure between the two faces is 100 kPa + 10 kPa. The measuring indicator is located on the top of the bar is connected with optical transducer.

Lab Hydrapulper is a complete pulping unit used for marking pulp from secondary fiber waste paper, on lab scale. It can also be used for mechno-chemical pulping. It has 30 liters capacity and can be also made available in 10 & 20 liters capacity, if required. The tub made of stainless steel, is provided with lid to fit tightly on the tub. There is an outer cover on the tub to make an access to the heaters and their connections. Four Heaters of 500 W each are fitted in the double wall annular space of the tub with glass wool as heat insulation to provide the heating controlled through thermostat. The Helicon Turbine fitted inside the tub is driven through V-Belt by the 5 HP motor at 500 RPM, for the desired time duration to form the pulp, at around 80 0C. The pulp samples can be checked by opening the top lid at intervals to ascertain its readiness.

Rapid Dryer is used for quick drying of wet pulp or paper samples before measuring dry weight, while determining moisture content. A wet sample of pulp or paper is placed between the upper and the lower drying plates of the dryer. The temperature of the dryer is adjustable, allowing precise control of the drying conditions.
After the prescribed drying time, the samples can be weighted to determine the moisture / solids content.

Floatation is a physical-chemicals process of separating materials. It is based on the phenomenon that separation is achieved by influencing the wet ability with water of the particles to be separated, whether the surface of these particles is hydrophilic or hydrophobic. The water repellency of the surface of the particles to be separated is achieved by the addition of special hetero polar chemicals, called collectors, which deposit on the surface of the particles. In the case of ore and mineral floatation, the polar metal- affined component of the collector deposits on the surface of the particle of the collector deposits on the surface of the particle so that the a polar component, mostly a CnN2n-1 chain, a with a dense packing of the adsorptive substance steeply erects on the surface of the particle, thus rendering it difficult to wet. At the same time, the treated particles can deposit on air bubbles that are introduced into the suspension, stabilized by frothers acting on the gas liquid boundary, as a result of the buoyancy of the air bubbles, the adhering particles are conveyed to the surface of the slurry or suspension to concentrate as froth, in which from they can be removed all hydrophilic particles remain in the slurry or suspension.
