Embodiment Construction

[0007] A waterproof treatment method for sound-absorbing panels. After weighing the test blocks mixed with permeable hydrophobic materials of different sizes and various proportions, they are directly soaked in water. First, a large number of air bubbles appear. After the air bubbles calm down, After standing for 30 minutes, take it out until there is no line of water curtain flowing down, and no more drops of water, then weigh it again, and place it in the air, observe the surface at 19h, 24h, and 3d, and weigh it , compared with that before entering the water, the water absorption rate is not more than 10%.

[0008] Table 1 below.

[0009] Table 1 is the water absorption test data of the present invention

[0010] .

[0011] The test of the sound absorption coefficient by the standing wave method is carried out under the condition that the humidity is greater than 40%.

Abstract

The invention provides a waterproofing treatment method of acoustic boards. The method comprises the following steps: after weighing different sizes of test pieces mixed with a permeable hydrophobic material according to various mixing ratios, directly immersing in water, and firstly generating a large number of bubbles; placing for 30 min after the bubbles are not abundantly generated, and then fishing out until a linear water curtain flows down without dripping water drops; weighing, placing in the air, observing the surface at 19h, 24h and 3d, weighing and comparing the weight before entering the water. According to the waterproofing treatment method of acoustic boards provided by the invention, the permeable hydrophobic material is used for waterproofing treatment in a test, and can permeate a certain thickness of a ceramsite surface to form a thin film material so that the absorption of the material to the water is prevented, the porosity characteristic of the material is not affected, and acoustic waves are not prevented from being adsorbed by the material.

Description

technical field [0001] The invention relates to a waterproof treatment method for a sound-absorbing panel, which belongs to the technical field of rails. Background technique [0002] In the process of waterproofing the existing sound-absorbing panels, either the process is relatively complicated, or the treatment process cannot meet the waterproof requirements, so that the sound-absorbing panels are easy to rot in a more complicated environment, and the life of the sound-absorbing panels is shortened. Contents of the invention [0003] The invention provides a waterproof treatment method for a sound-absorbing board, which has simple process and good waterproof effect. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a waterproof treatment method for sound-absorbing panels, after weighing the test blocks with different sizes and different mixing ratios mixed with permeable hydrophobic materials, they...
