Testing Equipment #198834

Our company is a well-known Manufacturer, Exporter and Supplier of Abrasion Tester. Abrasion Tester is used in application where elastomers are subjected to frequent rubbing or abrasive actions. As a part of its use, it is of prime importance to ensure that the formulation used has a full degree of resistance to abrasion. One of the methods for determining the abrasion resistance of elastomers is by a DIN type abrasion testing machine. In this test the elastomers under test is abraded against an abrading surface mounted over a rotating drum. The abrading surface has a specified abrading power. The test specimen which is in form of a button is held against it under a fixed load. The abrading surface is made to rub against the test specimen by rotating the drum at fixed speed, the test specimen being meanwhile made to move along the axis of the drum. The ratio of the volume loss in standard elastomers to the volume loss of the rubber under test, determined under the same conditions and the expressed as a percentage, gives the abrasion resistance index of the rubber under test. The determination of volume loss by this method is suitable for comparative testing and for checking the uniformity of specified products. However the results of this test give only limited information on the varying behavior of elastomers in practice.

 

Abrasion Tester is designed to determine the abrasion resistance index of natural and synthetic rubbers in accordance with the above principle. Abrasion Tester consists of the test specimen holder with a cylindrical opening adjustable between 15.3 and 16.3 mm to clamp the test specimen, with an arrangement to adjust the length of the test specimen protruding out. The holder is mounted on a swivable arm pivoted in a bracket which is moved laterally by a screw mechanism along the length of a rotating drum on which the abrasion cloth is fixed. The movement to the screw mechanism and drum is given by an electric motor coupled to a warm reduction gearbox with “V” belt and pulley to the specified speed of rotation to the drum and the specified lateral movement to the test specimen holder. The swivable arm and the test specimen holder are so disposed that the test specimen is pressed against the drum, the specified drum with its centre axis at an inclination of 3Deg to the perpendicular in the direction of rotation and placed above the longitudinal axis of the drum. The abrasive cloth is firmly fixed to the drum using a suitable, peel able adhesive with the ends of the abrasive cloth butt joined together. The equipment is provided with limit switches which, in addition of giving over travel safety to the movement of the test specimen holder, also stop the motor automatically after the specified run of the test specimen. An arrangement is also provided to protect the abrasive cloth from damage by the test specimen holder, by preventing lower edge of the test specimen holder to touch the abrasive cloth. The Abrasion Tester is built on the rigid steel base and finished in hammer tone painting and bright chrome/zinc plating to give it a corrosion resistant finish. Four abrasive cloths in addition to the fixed one on the cylinder are supplied with the equipment as the standard accessory. Moulding die and rotating type cutting die ( Hollow drill) for preparing the test specimens and extra abrasive cloths are available as optional accessories.

We are a chief Manufacturer, Exporter and Supplier of Shore Hardness Tester. The Shore Hardness Tester offered by us is used for a wide number of applications in various industries all over the globe. We supply highly efficient, durable and reliable Shore Hardness Tester at competitive prices.

 

The Shore Hardness is defined as the resistance to penetration by an indentor of specified shape under a defined load. Shore Hardness tester are available in various models for testing Vulcanized Rubber, Plastic, Ebonite, Fibre and all other soft and Hard Elastomers as per latest American Std ASTM-D 2240 and German Std DIN 53505. Shore A are suited for use on soft elastomers the hardness of which is between 10 and 90 Shore A. Shore D are suited for use on harder elastomer (hardness >80 Shore A) and on plastics the hardness of which is between 30 and 90 Shore D. Hardness is one of the most important properties which determine the suitability of any rubber component for its intended end use. Incorrect hardness may defeat the basic purposes for which the component is designed. Thus accurate and reliable determination of hardness is of extreme importance in rubber field. Related specifications ASTM D 2240-1986: Standard test method for rubber property- durometer hardness. JIS K 6301 – 1975 : Physical testing methods for vulcanized rubber.

The D-2 is an advanced pocketable hardness tester distinguished by its high accuracy, wide measuring range, simplicity of operation & above all it is a really portable instrument operating on three pencil cells of size AA. It is suitable for testing the hardness of many materials & finds applications for hardness testing in many areas of industry. Measuring Method : The measuring principle is based on absorption of kinetic energy & its relation in conventional scales of hardness. This is achieved with help of the probe, wherein a small body with a hard tip is propelled against the test surface by a spring & latch arrangement. The motion of body is the measure of its kinetic energy. The instrument converts the signal of absorbed energy in to a chosen scale of conventional hardness.

Useful for determining Edge Crush, Flat Crush, Pin (Ply) Adhesion of Corrugated Board and Ring Crush and CMT of Paper and Paperboards.

The principal behind determination of hardness by dead load apparatus is based on the measurement of the difference between the depth of indentation of a standard ball in to the rubber under a small contact force and a large indenting force. The Machine is as per IS-3400 (PART-II)1980.

Carbon Black Diapersion Tester is for analyzing dispersion of carbon. The microscope having line mark on the screen for measure the specimen. The hot plate retaining the S.S. cast plate for better heat distribution make thermal equilibrium of glass slides. The tong make very easy migration of slides from hotplate to microscope. The very operational ease instrument presenting here. CARBON BLACK CONTENT TESTER The carbon content in polyolefin and polyethylene more important as expressed as percentage. Because the utilization of carbon is not only as a pigment but also as UV absorber. The polyethylene material has tendency to be brittle in lower temp. which problem is eliminated by carbon. The higher percentage of carbon make material more loss in mechanical strength. So whatever which very necessary to control the percentage of carbon. It is rigid constructive carbon black content tester with custom made heater built in furnace has longer life. The glassware are of standard BOROSIL make.
