Description
Technical Field
The present disclosure relates to foam generators, and particularly to a novel foam generator capable of generating stable and controllable foam.
Background
High strength lightweight board is a trend in gypsum board development. There are two ways to reduce the sheet weight of gypsum boards: firstly, the foam holes in the gypsum board are increased, and the foam holes with uniform sizes can not only reduce the weight of the gypsum board, but also improve the heat insulation and sound insulation effects of the gypsum board; secondly, light materials are added into the gypsum board. However, typical add-on materials are incompatible with gypsum, and their addition can affect the bridging between the gypsum crystals, reducing the strength of the gypsum board. In order to avoid the influence on the strength of the gypsum board, the high-strength light board is prepared by increasing the number of the foam holes in the gypsum board, so that the added foam holes are required to be uniform and stable as much as possible.
The foaming agent commonly used in the gypsum board is a surfactant, the cost is increased by adopting the foaming agent with more stable performance, and the purposes of reducing weight and keeping strength are difficult to achieve by adopting the foaming agent with poor performance but low price. The foaming system that gypsum board manufacturing enterprise used now all adopts the pump to foam, and the foam stability that produces is relatively poor, and the size is difficult to control.
