Novel foam generator capable of preparing stable and size-controllable foam

Abstract

The invention relates to a novel foam generator capable of preparing stable and size-controllable foam. The novel foam generator comprises a mixing device, a foam screening and stabilizing device anda liquid collector; the inlet of the mixing device is configured to be connected with an air compressor and a foaming agent diluent storage tank through pipelines; the inlet of the foam screening andstabilizing device is connected with the outlet of the mixing device through a pipeline; a sieve plate and / or a silk screen are / is arranged in a pipeline between the inlet of the foam screening and stabilizing device and the outlet of the mixing device; a foam output pipe is arranged at the top of the foam screening and stabilizing device; a partition plate and / or a sieve plate are / is arranged inthe foam output pipe; and a liquid outlet is formed in the bottom of the foam screening and stabilizing device; and the liquid collector is connected with a liquid outlet in the bottom of the foam screening and stabilizing device through a pipeline. The foam generator is high in adaptability to foaming agents; foam prepared from foaming agents with the same performance is more stable, and the sizeof the foam can be adjusted and controlled; the preparation of gypsum boards with high strength and low piece weight is facilitated, and the production cost of the gypsum boards is reduced.

Description

technical field [0001] The present application relates to a foam generator, especially a novel foam generator capable of producing stable foam with controllable size. Background technique [0002] High-strength and lightweight panels are the development trend of gypsum boards. There are two ways to reduce the single weight of gypsum boards: one is to increase the cells in the gypsum boards, the cells of uniform size can not only reduce the weight of gypsum boards, but also improve the heat and sound insulation effect of gypsum boards; Add lightweight materials. However, general additional materials are incompatible with gypsum, and their addition will affect the overlap between gypsum crystals and reduce the strength of gypsum boards. In order to avoid the impact on the strength of gypsum boards, at present, high-strength and light-weight boards are prepared by increasing the number of cells in gypsum boards, which requires that the added cells be as uniform and stable as ...

AI Technical Summary

Problems solved by technology

[0003] The foaming agent commonly used in gypsum board is a surfactant. Using a foaming agent with more stable performance will increase the cost. Using a foaming agent with poor performance but low price will hardly achieve the purpose of reducing weight and maintaining strength.

The foaming systems currently used by gypsum board manufacturers all use pumps for foaming, and the foam produced is poor in stability and difficult to control in size
