海绵泡沫塑料落球回弹仪-（液晶显示）

泡沫海绵回弹率测试仪型号：HMLQ-500  

泡沫海绵回弹率测试仪制造标准：

(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

适用范围及功能：

适用于测定软质聚氨酯泡沫塑料的落球式回弹性能.落球回弹是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。主要是测试塑料泡沫材料及海绵材料的回弹性能。 落球回弹测量精度高采用微处理器进行控制，中文显示，并可打印试验数据。

技术参数：

　1、钢球回落高度：460mm（国标）  500mm（美标）

　2、钢球直径：￠16mm

　3、落球回弹率精度： <1%

　4、被测试样尺寸：长*宽*高=100 mm×100 mm×100（50）mm

   5、自动计算平均回弹高度

   6、自动计算平均回弹率

主要配置：

　1、试验主机一台

   2、智能液晶控制操作系统一台

   3、钢球释放机构两套（手动释放机构1套、自动释放机构1套）

   4、钢球捕捉机构一套

   5、高度调节机构一组

   6、精密光电传感器一套

   7、钢球4个

   8、微型打印机一台

   9、水平校准机构一组

试验步骤：

将调节后的试样水平置于回弹仪的测试位置上，通过调节使钢球底部从固定位置到泡沫塑料表面的落下高度为460mm。

在释放装置上固定钢球，然后使钢球自由落下。

对每一个试样做三次回弹，取三次回弹中的zui大值。

每次回弹钢球应落在试样表面的同一位置上，并且两次回弹的时间间隔应控制在20s之内。

如果钢球在回弹过程中碰到或弹出测量装置，所得数据无效，需重新补做。

Foam sponge resilient rate tester models: HMLQ - 500

Foam sponge resilient rate tester manufacturing standards:

(GB/T6670-2008 ISO8307 ASTM D3574 ISO8307) soft foam polymeric material resilience can measure the falling ball method

Foam sponge resilient rate tester is applicable range and function:

Is suitable for the determination of soft polyurethane foam falling ball type can rebound resilience. Falling ball springback is through a given diameter and the quality of the steel ball in the specified height on free falling on the foam sample, calculate the springback of maximum height of steel ball and ball drop height ratio is the percentage of spring rate, expressed as a resilient rate of foam plastics can rebound resilience. A and B meet the euro standard test method. Is primarily to test the plastic foam and sponge material can rebound resilience. Falling ball rebound high precision measurement using microprocessor to control, Chinese display, and can print the test data.

Foam sponge resilient rate tester technical parameters:

1, the steel ball drop height: 460 mm (gb) is 500 mm (American standard)

16 mm, ball diameter: 2 ￠

3, falling ball precision resilient rate: < 1%

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

5, and automatically calculate the average rebound height

6, calculated the average rebound rate automatically

Foam sponge resilient rate tester main configuration:

1, test host

A 2, smart LCD control operating system

3, release mechanism of steel ball two sets (1 set of manual release mechanism, automatic release mechanism (1 set)

4, a steel ball capture institutions

A set of 5, height adjustment institutions

6, precision photoelectric sensor is a set of

7, steel ball four

8, a miniature printer

A group of 9, level calibration institutions

Foam sponge resilient rate tester test steps:

Will be adjusted sample level in the test position of the hammer, by adjusting to the bottom of the steel ball from a fixed position to the foam on the surface of the drop height is 460 mm.

In the release device fixed ball, and then make the ball fell free.

Do the springback three times for each sample, take a maximum of three times the springback.

Every time the springback ball should fall on the same location on the surface of the specimen, and twice the springback of time interval should be controlled within 20 s.

If you meet or pop-up steel ball in the process of springback measuring device, the data is invalid, need to do.
