Abstract

The invention provides a rectangular glass reinforced plastic flue wallboard anti-torque laminated structure. The structure comprises a shell laminated plate; the shell laminated plate comprises twill; the twill comprises a first twill body and a second twill body which are mutually attached; the first twill body and the second twill body are perpendicular to each other; the twill has two opposite surfaces, and each surface is sequentially paved with unidirectional cloth, at least one layer of checked cloth, a chopped strand mat and a surfacing mat. According to the rectangular glass reinforced plastic flue wallboard anti-torque laminated structure, the twill, the checked cloth and the unidirectional cloth form a structure layer of the laminated structure, and the chopped strand mat and the surfacing mat form a surface layer of the laminated structure; inclined lines located in the center positions of the two twill bodies are perpendicular to one another, and accordingly the laminated structure forms the balanced and symmetrical anti-torque structure.

Description

technical field [0001] The invention relates to the installation technology of FRP wall boards, in particular to a torsion-resistant layer structure of FRP rectangular flue wall boards, and belongs to the technical field of FRP flue manufacturing. Background technique [0002] The FRP rectangular flue is composed of four FRP panels. Especially the desulfurization flue, its operating conditions are very complicated, mainly reflected in the following aspects: [0003] (1) Positive pressure: 5KPa; Negative pressure: -2KPa; [0004] (2) Multi-phase fluid scouring, the fastest speed is greater than 16 m / s, especially some air ducts are limited by the site location, there are too many dead angles in the air duct elbows, the effective flow section is large, and the actual flow velocity is as high as 24m / s. Caused frequent tearing of the air duct during operation, forcing the furnace to be shut down for repair welding; [0005] (3) Vibration, 20Hz vibration condition; vibration d...
