产品名称：落球回弹仪生产厂家
产品型号：HMLQ-500
显示方式：（液晶显示）
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.
具有一定质量和直径的钢球，从固定高度下落到试样表面，测量钢球弹起的高度，计算钢球弹起高度与下落高度比值的百分率。 该机采用微处理器进行控制，液晶中文显示，并可打印试验数据。 该机具有使用安全、可靠、测量精度高等特点。 依据标准: 依据标准：ASTM D3574及ISO8307:2007(软质泡沫聚合材料-落球法回弹性能的测定)， GB/T6670-2008(软质泡沫聚合村料落球法回弹性能的测定) 海绵泡沫塑料落球回弹测试仪通过标准规定直径和质量的钢球在规定高度上自由落在海绵泡沫塑料试样上，自动计算钢球回弹的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。
海绵泡沫塑料落球回弹测试仪采用微处理器进行控制，液晶屏显示中文操作，具有使用操作方便，性能可靠， 测量精度高等特点，并可打印试验数据。
技术规格:
钢球落下距离： 460±0.5%mm（国标）500±0.5%mm（美标） 钢球直径： ￠16±0.05 mm 落球回弹率精度： <1.5% 自动计算平均回弹调试 自动计算平均回弹率 产品特点:
1、既可做国标460 试样，又可做美标500 试样。（同类产品只能做国标460 试样）
2、液晶屏、中文显示，增加使用寿命的同时，易于理解，技术人员可快速掌握操作方法。（同类产品为数码管显示，只显示数字）
3、带打印功能，配备打印机。（同类产品无打印功能）
Scope of application and features:
Is suitable for the determination of soft polyurethane foam falling ball type can rebound resilience.
Have a certain quality and the diameter of steel ball, falling from a fixed height to the sample surface, measure the height of steel ball bounces, calculate the percentage of steel ball bounce height and drop height ratio. The machine USES microprocessor control, LCD display in Chinese, and we can print the test data. The machine has the use of safe, reliable, high measurement precision, etc. According to the standard: according to the standard: ASTM D3574 and ISO8307:2007 (soft foam polymeric material - falling ball method for the determination of resilience can), GB/T6670-2008 village (soft foam polymerization material falling ball method for the determination of resilience can) sponge foam falling ball springback tester by standard and quality of steel ball diameter in the specified height on free falling on the sponge foam plastics specimens, automatically calculate the springback of maximum height of steel ball and ball drop height ratio (both resilient rate), the percentage of resilience can expressed as a resilient rate foam plastics.
Sponge foam falling ball rebound test instrument using microprocessor control, LCD screen display Chinese operations, with use of convenient operation, reliable performance, high measurement precision, and can print the test data.
Technical specifications:
Ball falling distance: 460-500 mm (gb) 500 + / - 0.5% mm (American standard) ball diameter: ￠16 plus or minus 0.05 mm ball precision resilient rate: < 1.5% automatically calculates the average rebound debugging Calculated the average rebound rate automatically
Product features:
1, both can do gb 460 samples, and can do 500 American standard sample. (can only make similar product gb 460 sample)
2, LCD screen, Chinese display, as well as increase the service life, easy to understand, technical personnel can quickly master the operation method. (the same products for the digital tube display, show only the number)
3, with the function of print, equipped with a printer. (the same products no print function)
