海绵泡沫塑料落球回弹试验机-（液晶显示）制造标准：（GB/T6670-2008 ISO8307 ASTM D3574 ISO8307）软质泡沫聚合材料落球法回弹性能的测定

海绵泡沫塑料落球回弹试验机-（液晶显示）适用范围及功能：
回弹仪使用范围：是专业测海绵，泡沫，橡胶等软质材料而设计的一款高性价比的光学仪器。主要将钢球自由下落在软质泡沫塑料或其他弹性材料试样上。
测定其回弹高度的仪器，主要用于测定聚氨脂弹性材料测试项目中的回弹性能（回弹系数）。
参照中华人民共和国国家标准6670-96《软质泡沫塑料回弹性能的测定》

适用于测定软质聚氨酯泡沫塑料的落球式回弹性能.
落球回弹试验机通过给定直径和质量的钢球在规定高度上自由落在泡沫塑料试样上，
计算钢球回弹的zui大高度与钢球落下高度比值的百分率既回弹率，以回弹率表示泡沫塑料的回弹性能。满足08标准A法和B法试验方法。
回弹仪工作原理：海绵，泡沫，橡胶等材料成型后，至少应存放72小时才能进行测试。
测试前，试样应在温度23±2℃，相对湿度45%-50%的环境中进行状态调节至少16小时，然后在上述环境中进行测试。

Sponge foam ball rebound tester

Product Name: sponge foam ball rebound tester

Product type: HMLQ-500 display: LCD

Sponge foam ball rebound testing machine （liquid crystal display） manufacturing standards: （GB/T6670-2008 ISO8307 ASTM D3574 ISO8307） determination method of falling ball rebound performance soft foam polymerization

Sponge foam ball rebound testing machine （liquid crystal display） scope and function:

The scope of the use of rebound hammer: is a professional test sponge, foam,optical instrument design and soft materials such as rubber and a high performance price ratio. The ball free fall in a soft foam plastic or other flexible material specimen.

Determination of the rebound height of instrument, mainly used for the determination of resilience polyurethane elastic materials in test items （rebound coefficient）.

According to the national standard of the people's Republic of China 6670-96 "soft foam determination of resilience"

Suitable for performance ball rebound fell determination of soft polyurethane foam.

Falling ball rebound test machine through a ball given diameter and quality at a specified height free fall on the foam sample,

The maximum height of the ball and calculation of ball rebound height of fall the percentage of both the rebound rate, said resilience foam to rebound rate. To meet the 08 Standard Test methods A method and B method.

Rebound tester principle: sponge, foam, rubber and other materials after forming, at least should be stored for 72 hours before testing.

Before the test, the specimen shall be at a temperature of 23 ± 2 ℃, relative humidity 45%-50% environment for the conduct of state regulation for at least 16 hours, then the test is carried out in the environment.

Technical parameters:

Ball drop distance: 500 ± 0.5mm

The steel ball quality is: 16.8g ± 1.5g （the A method）

Ball drop distance: 460+0.5mm

The ball diameter: mm - 16-0.05 （16.3g）（the B method）

3, falling ball rebound rate accuracy: <1%

4, the test sample size: length * width * height =100 mm × 100 mm × 100 （50） mm

5, the instrument can automatically capture the ball rebound height （using highprecision photoelectric trap according to the calculation of ball drop rebound velocityprecision ball rebound height）

6, automatic calculation of the average rate of rebound

Main configuration:

1, test a host

2, inligent LCD control operating system a
