一、产品简介：

石膏板抗冲击测定仪是 石膏检测仪器，用于石膏装饰板之抗冲击强度测定。

Product introduction:

Gypsum board impact tester is a gypsum testing instrument for determining the impact strength of gypsum decorative boards.

二、技术参数：
♦钢球规格：50 毫米（GB308 一77 )
♦落球高度：500 , 1000 毫米
♦砂箱规格：360×360×70 毫米（容积）
♦仪器尺寸（长x 宽X 高）：430×370×789 ( 1289 )mm
♦仪器总重： 30 公斤
Technical parameters:

♦ Steel ball specifications: 50 mm (GB308-77)

♦ Falling ball height: 500, 1000 mm

♦ Sandbox specifications: 360 × 360 × 70 mm (volume)

♦ Instrument size (length x width x height): 430 × 370 × 789 (1289) mm

♦ Total instrument weight: 30 kg

三、使用方法：
♦将三块300300毫米的试件在40士2℃以下烘干至恒重（试件在24小时内的重量变化小于0.1%时即为恒重）在不吸湿的条件下，冷却至室温进行试验。
♦将仪器安放于水平的平台上，调节螺钉观察水准使仪器处于水平。
♦试验时，先用专用卡尺将砂箱内砂子刮平，纵横两个方向刮完，滑线指针即会在砂面上划出300300的凹线将试件对准刻线平整地放在砂面上。专用卡尺上设有调节板，松开螺钉即根据被测石膏的厚度不同，调节相对高度，以保证钢球至石膏板顶面50Omm或1000mm的高度。
♦本仪器落球高度为可调试，设有500mm和1000mm两档高度，作9mm厚石膏板测试时用500mm高度，小杆不必拉出，但必须注意销钉是否卡入小杆端部槽内（可以转动小杆凭手感判断）。作12mm板测试，即将调节套松开，拉出小杆，注意小杆上的红线必须对准观察孔尖，拉出后将销轴插入孔内，同上注意销钉必须卡入至小杆端部槽内，旋紧调节套，以下即可作冲击试验。
♦将磁座开关置于开的位置一即使磁路闭合，吸上钢球，再使磁座开关旋至关的位置，使钢球自由落下，测量石膏板冲击后的凹坑直径。
Second, use method:

♦ Dry three 300-300 mm test pieces to a constant weight below 40 ± 2 ° C (constant weight when the weight change of the test piece within 24 hours is less than 0.1%). Cool to room temperature without absorbing moisture. test.

♦ Set the instrument on a horizontal platform, adjust the screws to observe the level to make the instrument level.

♦ During the test, first use a special caliper to scrape the sａnd in the sａnd box. After scraping it in both the vertical and horizontal directions, the sliding line pointer will draw a 300300 concave line on the sａnd surface. Align the test piece with the score line and place it on the sand. Surface. The special caliper is provided with an adjustment plate. After loosening the screws, the relative height is adjusted according to the thickness of the measured gypsum to ensure that the height of the steel ball to the top surface of the gypsum board is 50 mm or 1000 mm.

♦ The height of the falling ball of this instrument is adjustable. It has two heights of 500mm and 1000mm. For the test of 9mm thick gypsum board, the height of 500mm is used. The small rod does not need to be pulled out, but you must pay attention to whether the pin is stuck in the groove at the end of the small rod. Turn the lever to judge by feel). For a 12mm plate test, just loosen the adjustment sleeve, pull out the small rod, pay attention to the red line on the small rod must be aligned with the tip of the observation hole, pull out the pin into the hole after pulling out, as above, note that the pin must be snapped to the end of the small rod Tighten the adjusting sleeve inside the groove, and the impact test can be performed as follows.

♦ Put the magnetic seat switch in the open position. Even if the magnetic circuit is closed, suck up the steel ball, and then turn the magnetic seat switch to the off position to make the steel ball fall freely.
