AI Technical Summary

Problems solved by technology

FRP septic tanks are generally buried 0.7 to 3.5 meters underground to save ground space. The ground can be used for greening, squares, roads, parking lots, etc. Therefore, the underground tank needs to withstand the upper soil pressure, side pressure, and ground pressure. Load (such as ground parking or vehicle traffic pressure) and multiple pressures such as uneven geological settlement stress, the tank must have sufficient strength to withstand external forces, so there are high requirements for the strength of the FRP septic tank itself, but now The existing technologies all have the problems of poor surface hardness and insufficient compression and bending resistance of buried storage tanks

Abstract

The invention discloses a composite suitable for a fiberglass septic tank. The composite comprises, by weight, 15%-25% of resin, 10%-25% of glass fiber cloth, 25%-30% of glass fiber short shreds, 20%-25% of calcium carbonate and 5%-10% of calcium chloride. The disclosed composite suitable for the fiberglass septic tank can well overcome the defects that an existing composite is poor in compression resistance and prone to corrosion, and a septic tank prepared through the composite is large in mass, poor in heat preservation performance, prone to leakage and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a composite material suitable for FRP septic tanks and a preparation method thereof. Background technique [0002] Septic tank is an indispensable drainage treatment equipment in the construction field. It is used to discharge domestic wastewater into municipal pipelines after primary treatment or into lower-level sewage treatment facilities for advanced treatment. Most of them are buried. In the early days, septic tanks were usually made of bricks, reinforced concrete or steel plates, but they all had obvious defects. In recent years, glass fiber reinforced plastic septic tanks have gradually been selected by most construction units. The scientific name of FRP is glass fiber reinforced plastic, and the septic tank storage tank made of FRP has the characteristics of strong corrosion resistance, no leakage, easy construction, and slow aging speed. The service life can rea...
