海绵泡沫回弹仪型号：HMLQ-500  

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。

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2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。

Product Name: sponge foam ball resilience meter - (liquid crystal display)
Model: HMLQ-500
One, manufacturing standards:
GB/T6670-2008 (ISO8307 ASTM D3574 ISO8307) soft foam polymeric material falling ball method for the determination of rebound performance
Two. Scope and function:
Application in the determination of soft polyurethane foam falling ball rebound performance. Falling ball rebound is through a ball given diameter and quality in a specified height free fall in the foam specimen, and calculate the ball rebound the maximum height and the ball falling height ratio of the percentage of both spring rate, said resilience foam to rebound rate. Meet 08 Standard A method and B test method. The springback of plastic foam and sponge is mainly tested.. The measuring accuracy of falling ball springback is controlled by the microprocessor, and the Chinese display and can print the test data..
Three, technical parameters:
1, the steel ball drop height: 460mm (GB)
500mm (American Standard)
2, the diameter of the steel ball of 16mm:
3. The accuracy of falling ball rebound rate: <1%
4, the size of the test sample: length * width * high mm mm x 100 =100 x 100 (50) mm
5, automatic calculation of average rebound height
6, automatic calculation of the average rebound rate
Four, the main configuration:
1, test host a
2, inligent LCD control operating system a platform
3, the ball release mechanism two sets (manual release mechanism 1 sets, automatic release mechanism 1 sets)
4, steel ball capture mechanism
5, a group of highly regulated organizations
6, a set of precision photoelectric sensor
7, steel ball 4
8, a micro printer
9. Horizontal calibration mechanism
Five. Test procedure:
The adjusted specimen level is placed in the test position of the rebound meter, and the height of the bottom of the steel ball from the fixed position to the foam surface is 460mm. Fix the steel ball on the release device, and then drop the ball freely.. The maximum of the three rebound is taken for three times of each sample.. Each time the rebound ball should fall at the same position of the specimen surface, and the interval between two rebound should be controlled within the 20s. If the steel ball touches or pops up the measuring device during the rebound process, the data is invalid and needs to be renewed..
