产品描述: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Z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。

产品概述

产品名称:海绵泡沫塑料落球回弹仪-(液晶显示)

型号:HMLQ-500  

一、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

 二、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。

三、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

四、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

五、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 rebound tester -liquid crystal display

Model: HMLQ-500

A, manufacturing standards:

GB/T6670-2008 ISO8307 ASTM D3574 ISO8307 determination method of falling ball rebound performance soft foam polymerization

Two, applicable scope and functions:

Suitable for performance ball rebound fell determination of soft polyurethane foam. Ball rebound is given by steel ball diameter and quality in the specified height of free fall on the foam specimen, the maximum height calculation of ball rebound the ball falling height and the percentage of both resilience, said resilient properties of foam to rebound rate. To meet the 08 Standard Test Method A method and B method. Mainly rebound performance test of plastic foam material and the sponge material. Ball rebound high measurement precision by using microprocessor to control, Chinese display, and print the test data.

Three, technical parameters:

1, the ball drop height: 460mmGB)

500mmAmerican Standard

2, the diameter of the steel ball: Phi 16mm

3, falling ball rebound rate of accuracy: 1% &lt;

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

5, automatic calculation of average rebound height

6, automatic calculation of average rate of rebound

Four, the main configuration:

1, test a host

2, inligent LCD control operating system a

3, two sets of ball release mechanismmanual release mechanism of 1 sets, 1 sets of automatic release mechanism

4, a steel ball catching mechanism

5, the height adjusting mechanism of a group

6, a set of precision photoelectric sensor

7, ball 4

8, a miniature printer

9, a group of horizontal alignment mechanism

Five, the test procedure:

Will test the position of the sample placed horizontally on the rebound instrument adjusted by adjusting the ball on the bottom, from a fixed position to the foam surface fall height of 460mm. Fixed ball in releasing device, and then the ball free fall. Do three rebound on every sample, a maximum value of three rebound. Each time the rebound ball should be in the same position on the sample surface, and the two rebound time interval should be controlled within 20s. If the ball on the rebound process encountered or pop-up measuring device, the data is invalid, need to do.
