Resistance To Surface Whear Apparatus

Resistance To Surface Whear Apparatus"NOVA" Makes Resistance To Surface Wear Apparatus (Abrasion Tester) For Decorative Lamination Sheet (As Per IS 2046:1995). This is specifically designed for Laboratory Testing of Decorative Lamination Sheet.The decorative surface of the sheet shall be sufficiently resistant to abrasion to protect its base layer from exposing in normal use. This ability to resist abrasion is determine by holding a circular test specimen taken from sheet & keeping over a horizontal platform & rubbing it with abrasive paper mounted over to cylindrical rubber disc. The test specimen is rotated at a fix speed of 60 +/- 2 RPM and the rubber disc rotates alongwith the platform due to fraction between them and test specimen.This causes the surface of the test specimen to abrade. The numbers of rotation required to bring about a defined degree of change in colors or wearing of the top layer gives a measure of abrasion resistant to the sheet under test.Construction"NOVA" Makes Resistance To Surface Wear Apparatus (Abrasion Tester) For Decorative Lamination Sheet (As per IS 2046:1995). It consists of a horizontal platform which rotates at a fix speed by synchro-set motor. Two Nos. cylindrical rubber cover wheels having width of 12.7mm & 50mm dia disposed symmetrically about the axis of the platform & located at 20mm in front of its centre with a loading arrangement to press the rubber disc against the surface of the specimen sheets under a specified load of 5.4 +/- 0.2 N on each. A programmable pre-set Digital counter with total revolution indication is provided to record the numbers of revolution of the platform and to step the motor after pre set program of revolution.10 Pairs of abrasive sheets of 12.7mm width & 160mm L made of aluminum oxide paper of either 180 or 220 grit with double side tape fixed at the back to stick them on rubber wheels are provided.A vacuum suction system is provided to remove the abraded dust from the surface of the test specimens.The equipment is finished in Powder Coated Paint.Technical DataPlatform Diameter: 140mmPlatform Rotation Speed: 60 + 2 RPMDimension of Rubber Disc: 50mm dia x 12.7mm widthHardness of Rubber Disc: 50 to 55 IRHD (Shore-A)Distance between Face of Disc: 50 to 55mmLoad of Rubber Disc: 5.4 + 0.2 N (550 + 20gm)Suction by Vacuum: 1.5 to 1.6 kPa minSuction Nozzle Distance: 77mmOther FeaturesRotation: By Digital Programmable CounterTotal Rotation Counting: On Digital DisplayVacuum Pump: Compact Vacuum Pump with Vacuum SystemOptionalCalibration plate for Abrasive Strip made of Rolled Zinc sheet use for checking of cutting powder should be arranged by customer or will be supplied at an extra cost.
