Store plate

Abstract

The invention discloses a store plate which comprises a face plate and a sandwich plate, wherein a color steel plate is used as the face plate, and a polystyrene foam sheet with a nitrogen-based flame retardant is used as the sandwich plate. Compared with the prior art, the store plate disclosed by the invention is small in thermal conductivity coefficient, good in heat preservation performance, and has less possibilities of absorbing moisture and being compressed; the polystyrene foam sheet contains a nitrogen-based flame retardant component, the nitrogen-based flame retardant is relatively stable and low in cost, and the function of the nitrogen-based flame retardant is comparable to that of a bromine-based flame retardant, and therefore, the store plate can achieve a fire prevention effect.

Description

technical field [0001] The invention relates to the technical field of controlled atmosphere storage, in particular to a storage panel of a controlled atmosphere storage. Background technique [0002] The controlled atmosphere storage is the most commonly used cold storage for storing fruits and vegetables. In the controlled atmosphere storage, the oxygen content is reduced to 1% to 10%, and the carbon dioxide content is increased to 1% to 10%. Such a storage environment can keep fruits and vegetables fresh when they are picked. temperature, reduce losses, and have a long fresh-keeping period without pollution; compared with cold storage, controlled atmosphere storage and fresh-keeping technology is more perfect. The storage boards that make up the air-conditioning storage are relatively common, such as foam glass boards and rock wool boards, which have high density and high thermal conductivity, which cannot achieve the effect of efficient heat insulation. Moreover, the cur...

Problems solved by technology

The storage boards that make up the air-conditioning storage are relatively common, such as foam glass boards and rock wool boards, which have high density and high thermal conductivity, which cannot achieve the effect of high-efficiency heat insulation. Moreover, the current cold storage has fire protection requirements. It is difficult for the library boards sold on the market to meet the requirements
