主要配置：
1、試驗(yàn)主機(jī)一臺(tái)
   2、智能液晶控制操作系統(tǒng)一臺(tái)
   3、鋼球釋放機(jī)構(gòu)兩套（手動(dòng)釋放機(jī)構(gòu)1套、自動(dòng)釋放機(jī)構(gòu)1套）
   4、鋼球捕捉機(jī)構(gòu)一套
   5、高度調(diào)節(jié)機(jī)構(gòu)一組
   6、精密光電傳感器一套
   7、鋼球2個(gè)
   8、微型打印機(jī)一臺(tái)
   9、水平校準(zhǔn)機(jī)構(gòu)一組
 
 

試驗(yàn)步驟：

將調(diào)節(jié)后的試樣水平置于回彈儀的測(cè)試位置上，通過調(diào)節(jié)使鋼球底部從固定位置到泡沫塑料表面的落下高度為460mm。

在釋放裝置上固定鋼球，然后使鋼球自由落下。

對(duì)每一個(gè)試樣做三次回彈，取三次回彈中的zui大值。

每次回彈鋼球應(yīng)落在試樣表面的同一位置上，并且兩次回彈的時(shí)間間隔應(yīng)控制在20s之內(nèi)。

如果鋼球在回彈過程中碰到或彈出測(cè)量裝置，所得數(shù)據(jù)無效，需重新補(bǔ)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..
