一,石膏砂浆保水率测定仪产品简介:
石膏保水率测定仪是专业检测仪器,依据中华人民共和国国家建材行业标准《粉刷石膏》(JC/T517-2004)而研制的用来检测粉刷石膏的保水率的测定,同时也可用于水泥、砂浆保水率试验。
First, the product introduction:
Gypsum water retention rate measuring instrument is a professional testing instrument. It is used to test the water retention rate of plastering plaster according to the national building materials industry standard "Stucco Plaster" (JC/T517-2004). It can also be used for cement and mortar. Water retention rate test.

三,石膏砂浆保水率测定仪实验步骤:
A、按布式漏斗内径裁剪中速定性滤纸一张,将其铺在漏斗底部,滤纸和滤纸用水浸湿。将布式漏斗放在抽滤瓶上,开启真空泵,抽滤一分钟,取下布式漏斗,用滤纸将下口残余供应商上海荣计达实验仪器有限公司的水擦净后称量(G1),精确至0.1克。
B、采用具有标准扩散度用水量的石膏浆放入称量后的布式漏斗内,用T型刮板在漏斗中垂直旋转刮平,使料浆厚度保持在(10±0.5)mm范围内,擦净布式漏斗内壁上的残余石膏浆,称量(G2),精确至0.1克。从搅拌完毕到称量完成的时间间隔不应大于5分钟。
C、将称量后的布式漏斗放到抽滤瓶上,开动真空泵。在三十秒之内将负压调至(53.33±0.67)kpa.抽滤20分钟,然后取下漏斗,用滤纸将下口残余水擦净,称量(G3),精度0.1克。
若连续两次测得的保水率与其平均值的差不大于3%,取该平均值作为试验的保水率,否则应该重做试验。
Third, the experimental steps:
A. Cut a medium-speed qualitative filter paper according to the inner diameter of the cloth funnel, spread it on the bottom of the funnel, and filter the filter paper and filter paper with water. Place the cloth funnel on the suction filter bottle, turn on the vacuum pump, filter for one minute, remove the cloth funnel, and wipe the water from the remaining supplier of Shanghai Rongjida Experimental Instrument Co., Ltd. with the filter paper (G1). ), accurate to 0.1 grams.
B. Gypsum slurry with standard diffusion water consumption is placed in the weighing cloth funnel, and the T-shaped scraper is vertically rotated and scraped in the funnel to keep the slurry thickness within the range of (10±0.5) mm. The residual gypsum slurry on the inner wall of the cloth funnel is wiped and weighed (G2) to the nearest 0.1 gram. The time interval from the completion of the agitation to the completion of the weighing should not exceed 5 minutes.
C. Place the weighed cloth funnel on the suction filter bottle and start the vacuum pump. The negative pressure was adjusted to (53.33±0.67) kpa within 30 seconds. After suction filtration for 20 minutes, the funnel was taken out, and the residual water of the lower mouth was wiped clean with a filter paper, and weighed (G3) with an accuracy of 0.1 g.
If the difference between the water retention rate measured twice and its average value is not more than 3%, the average value is taken as the water retention rate of the test, otherwise the test should be repeated.


四,石膏砂浆保水率测定仪产品结构:
石膏砂浆保水率测定仪主要由旋片式真空泵、耐震真空表、抽滤瓶、布氏漏斗等部分组成,控制系统方便灵活,易于操作,整机布局合理,层次分明,适合各级质量检测部门及用户的使用。

Fourth, the product structure:
Gypsum mortar water retention rate measuring instrument is mainly composed of rotary vane vacuum pump, shockproof vacuum gauge, suction filter bottle, Buchner funnel, etc. The control system is convenient, flexible and easy to operate. The layout of the whole machine is reasonable and the level is clear. It is suitable for quality inspection departments at all levels. And the use of the user.
