Product Introduction

Most products will inevitably come into contact with or even rub against other objects in the environment during transport or use. Part of the failure of functions, such as fading, fuzzy patterns, surface wear, etc. So there is the wear test. So, what are the types of wear tests? Hear what Shanghai Qianshi has to say about this issue!

What are the types of wear tests? According to Shanghai Qianshi, the wear resistance test of the product can obtain information about the reliability of the product, such as wear resistance, and the manufacturer can improve the product material or design based on this information. That is why wear tests play a crucial role in improving product reliability.

1. Linear Reciprocating Friction

Suitable for wear testing of plastics, auto parts, rubber, leather, textiles, electroplating, freely disassembled components, paints, printed patterns and other products with contoured surfaces and polished surfaces, both dry and wet abrasion tests can be performed.

11 optional standard displacement distances: 0.2, 0.5, 0.61, 0.75, 1.0, 1.5, 2 .0, 2.5, 3.0, 3.5 and 4.0”

Special movement distance can be adjusted

Adjustable movement from 2 to 75 reciprocating/min Speed, including 2, 15, 25, 30, 40 and 60 reciprocating/min, these six speeds are preset with 6 buttons on the control panel.

Adjustable number of revolutions: up to 999,999 revolutions can be set (please note that the rubber of the sanding head may need to be replaced during this period)

Optional load: standard load ranges from 350g to 2100g(generally arbitrarily configure 3 weights with a weight of 250g.)

Meets standards: ASTM D3884, ASTM D1175, ASTM D1044, ASTM D4060, TAPPIT476, ISO 9352, ISO 5470-1, JIS K7204, JIS A1453, JIS K6902, JIS L1096, JIS K6964, DIN 52347, DIN 53109, DIN 53754, DIN 53799, in accordance with CE standards, with CE safety marking.

2. Rotational friction

Mainly due to rotation The grinding method uses different types of friction wheels rotating on the sample to test the wear resistance of leather and plastic materials. Select the default applicable weight set for testing material properties. Detect weight loss on the outer surface of the sample, such as obvious mechanical damage.

Test piece: outer diameter 108 mm, inner diameter 8 mm, 3 mm (D)

Grinding wheel: diameter 2” ( M *45mm)1/2”(W)

Center distance wwheel: 63.5 mm

Center of grinding wheel and test wheel Distance: 37~38 mm

Rotational speed: 60/72 rpm

Weight: 250g, 500g, 1000g

Counter: LCD, 0~999,999

Volume: 530×320×310+vacuum cleaner

Weight: 18kg (without vacuum cleaner)

Power supply: 1φ , 220v/50HZ

Wear index Calculation formula: wear loss weight/speed × 100 1. JIS K7204, JIS A1453, JIS K6902, JIS L1096 , JIS K6964, DIN 52347, DIN 53109, DIN 53754, DIN 53799 and other standards

3 .Reciprocating friction

Used to detect the scratch resistance of coatings, plastics, decorative fabrics, car interiors, pile fabrics, etc. Friction and wear resistance.

Stroke range: 6-120mm adjustable

Speed ​​range: 1-100 reciprocating/min infinitely adjustable

LCD screen control, you can set paraset gauges such as speed and reciprocating times

The LCD screen displays the test status and controls it in real time. The two-station design saves time for the test.

Meets the requirements of various standards and can be equipped with weights and weights according to users' needs. Friction head

Weight: about 48.5kg

Size: 532mm *471mm*630mm(W*D*H)
