^{將調(diào)節(jié)后的試樣水平置于回彈儀的測試位置上，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量裝置，所得數(shù)據(jù)無效，需重新補(bǔ)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: 460mm （GB）

500mm （American Standard）

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

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

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

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 mechanism （manual 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.
