一、產品簡介：
石膏板抗沖擊測定儀是 石膏檢測儀器，用于石膏裝飾板之抗沖擊強度測定。
Product introduction:
Gypsum board impact tester is a gypsum testing instrument for determining the impact strength of gypsum decorative boards.
二、技術參數：
?鋼球規格：50 毫米（GB308 一77 )
?落球高度：500 , 1000 毫米
?砂箱規格：360×360×70 毫米（容積）
?儀器尺寸（長x 寬X 高）：430×370×789 ( 1289 )mm
?儀器總重： 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：
?將三塊300300毫米的試件在40士2℃以下烘干至恒重（試件在24小時內的重量變化小于0.1%時即為恒重）在不吸濕的條件下，冷卻至室溫進行試驗。
?將儀器安放于水平的平臺上，調節螺釘觀察水準使儀器處于水平。
?試驗時，先用專用卡尺將砂箱內砂子刮平，縱橫兩個方向刮完，滑線指針即會在砂面上劃出300300的凹線將試件對準刻線平整地放在砂面上。專用卡尺上設有調節板，松開螺釘即根據被測石膏的厚度不同，調節相對高度，以保證鋼球至石膏板頂面50Omm或1000mm的高度。
?本儀器落球高度為可調試，設有500mm和1000mm兩檔高度，作9mm厚石膏板測試時用500mm高度，小桿不必拉出，但必須注意銷釘是否卡入小桿端部槽內（可以轉動小桿憑手感判斷）。作12mm板測試，即將調節套松開，拉出小桿，注意小桿上的紅線必須對準觀察孔尖，拉出后將銷軸插入孔內，同上注意銷釘必須卡入至小桿端部槽內，旋緊調節套，以下即可作沖擊試驗。
?將磁座開關置于開的位置一即使磁路閉合，吸上鋼球，再使磁座開關旋至關的位置，使鋼球自由落下，測量石膏板沖擊后的凹坑直徑。
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.
