(GB/T6670-2008 ISO8307 ASTM D3574 ISO8307)軟質(zhì)泡沫聚合材料落球法回彈性能的測(cè)定
適用范圍及功能：
適用于測(cè)定軟質(zhì)聚氨酯泡沫塑料的落球式回彈性能.落球回彈是通過(guò)給定直徑和質(zhì)量的鋼球在規(guī)定高度上自由落在泡沫塑料試樣上，計(jì)算鋼球回彈的zui大高度與鋼球落下高度比值的百分率既回彈率，以回彈率表示泡沫塑料的回彈性能。滿足08標(biāo)準(zhǔn)A法和B法試驗(yàn)方法。主要是測(cè)試塑料泡沫材料及海綿材料的回彈性能。 落球回彈測(cè)量精度高采用微處理器進(jìn)行控制，中文顯示，并可打印試驗(yàn)數(shù)據(jù)。
技術(shù)參數(shù)：
1、鋼球回落高度：460mm（國(guó)標(biāo)） 500mm（美標(biāo)）
2、鋼球直徑：￠16mm
3、落球回彈率精度： <1%
4、被測(cè)試樣尺寸：長(zhǎng)*寬*高=100 mm×100 mm×100（50）mm
5、自動(dòng)計(jì)算平均回彈高度
6、自動(dòng)計(jì)算平均回彈率
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）

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4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(guò)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(guò)程中碰到或彈出測(cè)量裝置，所得數(shù)據(jù)無(wú)效，需重新補(bǔ)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.
