Embodiment Construction

[0009] To prepare a combined biogas digester, the pond body can be in the shape of a barrel, the middle body is composed of two symmetrical half-barrels, and the upper end has a dome-shaped cover. Thus, a corresponding mold is made.

[0010] Get magnesium oxide 100kg, magnesium chloride aqueous solution 70kg. After mixing and stirring evenly, spread it evenly on the mold, and then spread the glass fiber cloth, and repeat this until the thickness reaches 3-4cm, and at this time there are about 8 layers of glass fiber cloth. Then it is cured at room temperature. After demoulding, it is cured, naturally dried, trimmed and put into storage. When used, the components are transported to the installation site for assembly and molding.

Abstract

The invention discloses a composite material for preparing modular mathane-generating pit, which comprises woven glass fabric, magnesia and magnesium chloride aqueous solution, wherein the weight ratio of magnesia and magnesium chloride aqueous solution is 100 : 70-80. The material can reduce production cost substantially.

Description

Technical field [0001] The invention relates to a building material, in particular to a composite material used for preparing an assembled biogas pit. Background technique [0002] At present, most biogas digesters are made of cement concrete, which has the disadvantages of poor designability, poor thermal insulation, cumbersome manufacturing process, long construction period, and inconvenient industrial prefabrication. In order to solve this problem, a kind of fiberglass digester has appeared now. The biogas digester is composed of unsaturated polyester resin, gel coat resin, multi-layer glass fiber and other materials. Although it has achieved industrialized mass production, it is easy to standardize, serialize and standardize products. It has the advantages of light weight and easy installation. However, the high cost of the biogas digester greatly affects its wide application. Contents of the invention [0003] The purpose of the present invention is to provide a n...
