A.4.1 Fill the specimen with the mortar of 61mmX70mmX2cm as described above, and control the wet thickness to 2mm. The surface is half-sealed and free of bubbles. After curing under standard environment, the four sides and bottom of the test block are calibrated with 111% rosin and wax-free mud. The diameter should be uniform, free of friction, and not contaminated by the standard surface. The length of each side should be less than 61mm. Then place the sample in the standard environment. Prepare the final sample
A. 4. 2 Test steps: Use medical cloth to remove the grease on the surface of the test block, connect the test block to the center of the test stand, and place the test block on a water frame. The frame should be in contact with the surface of the test block to keep the test block level. The water environment meets the requirements of Class 2 water in MA 682. The test block is taken out of the water. Use a medium-speed qualitative glass to gently remove the water on the surface within about 10:1 hour. The mass of the test block is measured at a speed of 3.1g: + E.5 Calculate the water absorption W of the sand surface. Calculate the result according to the following formula: W. ——Water absorption, single unit is gram ()

B.3.1 Use a special putty to scrape the prepared putty on the stone comb water seepage board, wet The film thickness is 2nm, and the surface is kept intact. Large bubbles: Maintain the washed test panels in a standard environment for 1 day. Prepare 3 test panels for each product (as shown in B.1). B.3.2 Place the test stand on the dynamic system test stand (as shown in B.2 above). There is a natural layer of film. Turn the rod to F. The knife is on the knife. When the knife contacts the test, the ball seat should be raised slowly. Pay attention to the blank area of ​​the asbestos board. When cracks are found, use a reading microscope to observe the product and record the width of the cracks. It should be placed horizontally to ensure that the focal length is appropriate and the measurement is clear. If necessary, auxiliary lighting equipment can be used to ensure the accuracy of observation. B.3.3 Record the test results of cement cracking before the layer is reduced. The accuracy is 0.02mm. The technical level of the test tool of two test boards (the numerical value of the test board) among the three test boards is used as the final result. Figure B.1 Dynamic swell test board Dynamic anti-disintegration tester diagram JC/T157-20042 Type inspection shall be conducted in any of the following cases: a) New product trial production and finalization appraisal; b) Changes in the main raw material dosage of the product; c) Production process changes significantly; d) The production suspension rate is above 100%; d) The production resumption time is short; d) The national technical supervision organization proposes type inspection; 7.2 Determination of inspection results; 7.2.1 The inspection results shall be determined in accordance with the modified value comparison method of GB/1250. 7.2.2 When the inspection results meet the technical requirements of this standard, the product is in compliance with the requirements of this standard. If the inspection results meet the technical requirements of this standard, the preserved samples shall be tested. If the test results still do not meet the technical requirements of the standard, the product is in compliance with the requirements of this standard. 8 Marking, packaging and storage; 8.1 Marking shall be carried out in accordance with the provisions of IEC 6001-1999. If water dilution is required, the dilution ratio should be confirmed. 8.2 Packaging and Safety: The packaging requirements of CB/T184U should be followed. 8.3 Storage: Ventilation should be maintained during storage before transportation, and direct sunlight should be avoided. Appropriate storage should be adopted for non-static components. The storage period should be determined according to the product type and clearly indicated on the packaging mark. JG/T 157—2004
