一、產(chǎn)品簡介：
砂漿含氣量測定儀是我公司依據(jù)JGJ/T70-2009（建筑砂漿基本性能試驗方法標準）和JISA1228規(guī)范，用于測量砂漿中的空氣含量。測定原理是根據(jù)氣態(tài)方程，保持一定壓力的氣室和裝滿試料的容器之間，開閉壓力平衡，兩個容器內(nèi)的壓力達到平衡時，氣室里壓力減少的量即是砂漿中空氣所占的百分比，在壓力表上顯示出的即是試料中的空氣含量。
Product introduction:
The mortar gas content measuring instrument is used by our company to measure the air content in mortar according to JGJ / T70-2009 (standard for basic performance test methods of building mortar) and JISA1228. The measurement principle is based on the gaseous equation. The pressure between the gas chamber that maintains a certain pressure and the container filled with the sample is balanced. When the pressure in the two containers reaches equilibrium, the pressure in the gas chamber is the air in the mortar. The percentage that is shown on the pressure gauge is the air content in the sample.
二、工作原理：
根據(jù)氣態(tài)方程，保持一定壓力的氣室和裝滿試料的容器之間，開閉壓力平衡時，兩個容器的壓力達到平衡時，氣室壓力減少的量即是砂漿中的空氣含量所占的百分比，在壓力表上表示出的即是試料中的空氣含量。
Second, the working principle:
According to the gas state equation, between the gas chamber that maintains a certain pressure and the container filled with the sample, when the opening and closing pressure is balanced, when the pressure of the two containers reaches equilibrium, the amount of pressure reduction in the gas chamber is the air content in the mortar. The percentage is shown on the pressure gauge as the air content in the sample.
三、技術(shù)參數(shù)：
★壓力表：0-0.1mpa
★含氣量值:1%-20%直讀
★量缽容積:1L
★外形尺寸：200X320mm
★重量：4kg
Fourth, the technical parameters:
★ Pressure gauge: 0-0.1mpa
Gas content value: 1% -20% direct reading
Measuring bowl volume: 1L
★ Dimensions: 200X320mm
★ Weight: 4kg
四、使用方法:
★將拌好的混凝土分二次裝入缽體，
★分別振實，排除氣泡，刮去表面多余部分，
★蓋上蓋子，將壓緊閥對襯均勻擰緊，關(guān)閉所有閥門。
★用充氣閥充氣至――。點的位置，停3-5秒，
★按動進氣閥，表針所指的位置 是混凝土含氣量的實測數(shù)值（紅色）
★測定完畢，緩慢的松動調(diào)壓閥，
★使表針慢慢的回到零點，A猛松，防止指針撞擊零點定位柱，影響精度。
Five, use method:
★ Put the mixed concrete into the bowl twice,
★ Simulate separately, eliminate air bubbles, scrape off excess surface,
★ Close the lid, tighten the compression valve evenly and close all valves.
★ Inflate with inflation valve to ——. Point position, stop for 3-5 seconds,
★ Press the air inlet valve, the position indicated by the hａnd is the actual measured value of the concrete air content (red)
★ After the measurement is completed, slowly loosen the pressure regulating valve,
★ Make the hａnd slowly return to zero, and A will loosen, preventing the pointer from hitting the zero positioning column, affecting the accuracy.
