Gypsum board foaming mixing equipment and mixing method

Abstract

The invention relates to gypsum board foaming mixing equipment. The gypsum board foaming mixing equipment is characterized in that a foaming agent storage tank is connected to a mixer sequentially through a foaming agent pump, a foaming mixing pump and a pair of beating pumps via foaming agent conveying pipelines; a clean water inlet and a compressed air inlet are connected between the foaming agent pump and a foaming mixing pump; an outlet of the foaming agent mixing pipeline is arranged at the outer side of a material outlet of the mixer. The gypsum board foaming mixing equipment has the advantages that the adding position of a foaming agent is adjusted from the interior of the mixer to the outlet of the mixer, and the direction of the outlet is tangential to the rotation direction of the mixer, so as to ensure the mixing effect of the foaming agent and slurry, and reduce the foam loss of the foaming agent in the mixer; by adjusting and controlling the foaming system, the dense smallgas pore structure of a paper-surface gypsum board core is changed into a honeycomb-shaped large gas pore structure, so that at the premise of ensuring the strength and adhering property of the gypsum board, the weight is reduced, the toughness is improved, the defects of poor toughness, easiness in moisture absorbing and deformation and the like are overcome, the foaming effect is improved, andthe foaming efficiency is improved.

Description

technical field [0001] The invention relates to a gypsum board foam mixing equipment and a mixing method. Background technique [0002] Gypsum board materials generally reduce weight, improve sound insulation performance, and enhance toughness by adding foaming agents. Foaming agents are added to other raw materials and mixed in the mixer. After being ejected from the mixer outlet, they enter the molding system for molding. Traditional The foaming agent addition port is set inside the mixer, and the foaming agent is mixed with other raw materials in the mixer, and the foaming agent will have a certain loss during the mixing process of the foaming agent and other raw materials in the mixer. It affects the foaming efficiency and the uniformity of the core pores. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gypsum board foaming mixing equipment and mixing method that can improve the foaming effect and increase...
