Shanghai-Multifunctional scratch tool

Author:QINSUN Released in:2023-04 Click:31

Shanghai multi-function scratch tester is also called scratch tester, scratch tester, scratch tester, five-finger scratch resistance tester, scratch resistance tester, scratch resistance tester, scratch tester, scratch tester. Suitable for testing the scratch resistance of various car interior materials, such as plastics, rubber, leather, fabrics, coated materials, uncoated materials and other composite materials

Product Introduction

The utility model refers to a multifunctional scratch-resistant instrument, including a housing and a working platform. The working platform is supported and installed on the housing by double guide rails. Insert it into the spline sleeve of the five-finger scraper support frame. The five-finger scraping support frame is installed on the left end column, and the support framee with one hundred grids is installed on the right end column. There is a sliding frame with a hundred grids inside. In the spline sleeve of the method support frame, the Baige method sample support frame is installed on the working platform, the control system is installed on the housing, and an automatic control circuit is arranged in the control system electrical box. The utility model has the function of flexibly switching between multiple testing methods, such as five-finger scratching, hundred-grid scratching, plastic finger scratching, etc., one machine with multiple functions, effectively saving the cost of testing equipment, saving testing time , and performing the tests at once All tests of scratch resistance of automotive interior materials Melt

Multifunctional scratch resistance tester is also called scratch resistance tester, scratch resistancecalled dtester, scratch resistance tester, five-finger scratch resistance tester, scratch resistance tester, scratch resistance tester, scratch tester, scratch tester. Suitable for For all kinds of car interior materials, such as plastic, Scratch resistance testing of rubber, leather, fabric, coated materials , uncoated materials and other composite materials.

scraping principle:

This test method is used to test the ability of surface materials to resist damage caused by scratching fingers. According to the nails or other hard objects that may contact the material, scraping fingers of different materials are used to act on the surface of the sample with a certain pressure according to the specified direction, stroke and speed, and the sscraping head and the sample make a relative movement, resulting in one-way, non-reciprocating linear scraping path, the scratches are kept parallel. The final assessment of the scratch sensitivity of the material, the color difference between the scratched area and the unscratched area, or the minimum scratching force when the sample surface is damaged.

Instrument attributes:

1. The instrument is assembled of motor drive mechanism, scraper structure, sample clamping and fixing device, etc.

2. The scraper components include scraper brackets, scraper fingers and scraper sleeves, pressure booster (weight and weight support bar), etc.

3. The instrument can freely install, replace and disassemble scraping fingers of different specifications. uniform linear scraping movement in one direction under different loads.

4. Use an embedded system and human-machine interface to automate the testing process The control uses precise servo motor and ball screw drive, which has a decisive plays a role in the accuracy of the scraper speed control under the relevant standards.

5. Use tungsten carbide as a scraper finger to prolong the life of the instrument.

6. Made of aluminum alloy and stainless steel, the appearance is simple, light and corrosion resistant
