Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0026] Such as figure 1 Shown, a kind of water absorption detection method of architectural ceramics, comprises the steps:

[0027] a. Sampling, dig out sample blocks of the same volume at the four corners and the middle of the sample brick to be tested, as a test sample;

[0028] b. Sample processing, weighing the sample after drying to obtain the dry weight W of the test sample;

[0029] c. Vacuum test, put the weighed test sample into a vacuum tank, vacuumize the item, while maintaining the vacuum, open the water supply valve to submerge the test sample, soak for 15 minutes, and drain the water in the vacuum tank , open the vacuum tank after inflating the vacuum tank, and take out the test sample;

[0030] d. Weighing, dry the moisture on the surface of the test sample with a wet towel contain...

Abstract

The invention aims to provide a water absorption detection method of building ceramics. The water absorption detection method includes the steps: a sampling: digging sample blocks with same sizes fromfour corners and the middle of a sample brick to be detected, and enabling the dug sample blocks to serve as detection samples; b sample treatment: drying samples, and weighing the dried samples to obtain drying weight W of the detection samples; c vacuum detection: placing weighed detection samples in a vacuum tank, performing vacuum pumping treatment on the samples, keeping vacuum, opening a water feeding valve, submerging the detection samples, soaking the samples for 15 minutes, discharging water in the vacuum tank, filling the vacuum tank with air, opening the vacuum tank, and taking outof the detection samples; d weighing: wiping dry the surfaces of the detection samples by the aid of a wet towel with a certain moisture, and performing weighing to obtain contained water weight W1;e calculating water content. Water absorption%=(W1-W)/W*100%. According to the method, moisture of the detection samples is not lost, and detection accuracy rate is ensured.

Description

technical field [0001] The invention relates to the technical field of performance detection of architectural ceramics, in particular to a water absorption detection method of architectural ceramics. Background technique [0002] Water absorption refers to the amount of water absorbed by ceramic tiles, and it is also one of the important indicators to measure the quality of ceramic tiles. The size of the water absorption reflects the internal voids and the density of the structure of the ceramic tile. The greater the water absorption, the more internal voids, the looser the structure, and the lower the strength of the ceramic tile; on the contrary, the smaller the void, the denser the structure. The higher the strength of the brick. [0003] The current detection of moisture content of ceramic tiles is relatively rough, and the detection methods are inconsistent, resulting in inconsistent detection results, which may lead to uneven quality of batches of products, so a relat...
