Embodiment Construction

[0017] Further describe the present invention below in conjunction with embodiment and accompanying drawing thereof:

[0018] Perlite sound-absorbing board mixing process designed by the present invention (referred to as mixing process, see figure 1 ), the mixing process includes the following steps:

[0019] (1), preparation of water glass solution

[0020] Put the sodium silicate solid directly into the water glass tank 1, so that the sodium silicate and water fully react and liquefy into a water glass solution with a mass concentration of 1.3×10 3 kg / m 3 , use after the mixing temperature drops below 40C°;

[0021] (2), transport water glass solution

[0022] Use the liquefied screw pump 22 to transport the water glass solution from the pipeline to the batching tank 19, and the delivery pipeline is equipped with a batching electric valve 20 that is convenient for automatic control;

[0023] (3), preparation of adhesive

[0024] Add other materials required by the proc...

Description

technical field [0001] The invention relates to a sound-absorbing board preparation technology, in particular to a material mixing process and equipment for a sound-absorbing board using perlite powder and an adhesive as raw materials. The main process of accurate mixing is to pump the liquefied water glass into the water glass batching tank, mix it with other ingredients, and stir it evenly to become an adhesive. By precisely controlling the flow rate of the adhesive and perlite powder The volume of the material realizes the automatic batching of perlite sound-absorbing board raw materials, precise mixing, and streamlined production process. Background technique [0002] As a decorative material, sound-absorbing panels are mainly used in places with high requirements for noise isolation, including wooden sound-absorbing panels, mineral sound-absorbing panels, polyester fiber sound-absorbing panels, metal sound-absorbing panels, etc. As a raw material for sound-absorbing pa...
