preparation example Construction

[0066] The preparation method of FRP chimney of the present invention comprises the following steps:

[0067] (a) making the lining functional layer;

[0068] (b) laying (making) the intermediate structural layer outside the inner lining functional layer, and optionally

[0069] (c) laying (making) the outer protection layer outside the intermediate structure layer to obtain the glass fiber reinforced plastic chimney;

[0070] or include the following steps:

[0071] (a) providing an inner liner functional layer, an intermediate structural layer, and an optional outer protective layer;

[0072] (b) Assembling the inner lining functional layer, intermediate structural layer, and optional outer protective layer into the FRP chimney.

[0073] The fiberglass chimney of the present invention has one or more of the following features:

[0074] (1) The hoop tensile strength is greater than 235MPa, the modulus is greater than 19.0GPa, the axial tensile strength is greater than 110...

Embodiment 1

[0169] The fiberglass chimney of this embodiment includes an inner lining functional layer, an intermediate structural layer and an outer protective layer, with a diameter of 7 meters.

[0170] Wherein, the lining functional layer includes a surface felt layer and a sprayed yarn layer from the inside to the outside, with a thickness of 1.2mm.

[0171] The middle structural layer is composed of 6 structural sub-layers 1 from inside to outside, 2 additional structural single layers and 1 outermost structural single layer. The structure is S1-S1-S1-F1-F2-S1-S1-S1-Y2. The thickness is 18.5mm.

[0172] The outer protective layer is a gel coat layer with a thickness of 0.25mm.

Embodiment 2

[0174] The fiberglass chimney of this embodiment includes an inner lining functional layer, an intermediate structural layer and an outer protective layer, with a diameter of 7.5 meters.

[0175] Among them, the lining functional layer is composed of carbon fiber felt layer, surface felt layer and jet yarn layer from inside to outside, with a thickness of 1.5mm.

[0176] The structure of the middle structure layer from inside to outside is S1-S1-S1-F1-S1-S2-F1-F2-S1-S4, and the total thickness of the middle structure layer is 19.5mm.

[0177] The outer protective layer is a gel coat layer with a thickness of 0.25mm.

Abstract

The invention relates to a glass reinforced plastic chimney with medium thickness. The cylinder wall of the chimney comprises a lining functional layer, a middle structural layer and an optional outer protective layer. The middle structural layer comprises a plurality of structural sub-layers. The structural sub-layers comprises a structural single layer A, a structural single layer B, a structural single layer C and a structural single layer D from the inside to the outside of the glass reinforced plastic chimney. The structural single layer A is a spraying yarn layer or unidirectional cloth layer. The structural single layer B is an undirected or circumferential winding layer. The structural single layer C is a spraying yarn layer or unidirectional cloth layer. The structural single layer D is a circumferential winding layer. When the structural single layer A is the spraying yarn layer, the structural single layer C is the unidirectional cloth layer; or when the structural single layer A is the unidirectional cloth layer, the structural single layer C is the spraying yarn layer; the thickness t of the middle structural layer is larger than or equal to 18mm but smaller than 24mm. The glass reinforced plastic chimney has good axial mechanical property and circumferential mechanical property, and is convenient to construct and control quality, long in service life and applicable to large thermal power plants.

Description

technical field [0001] The invention relates to a chimney, in particular to a medium-thick glass fiber reinforced plastic chimney. Background technique [0002] Fiber-reinforced plastics are high-performance composite materials formed with fibers and their products as reinforcing materials, synthetic resin as matrix materials, and a specific molding process. Glass Fiber Reinforced Plastics (Glass Fiber Reinforced Plastics, also known as glass fiber reinforced plastics, the internationally recognized abbreviation symbol is GFRP or FRP) is a kind of fiber reinforced plastics, which is a functional type made of synthetic resin and glass fiber through a composite process. Composite materials have excellent designability, processability and repairability. [0003] In the past, domestic FRP was mostly used for storage tanks and pipelines. Its material design focused on meeting product functions and did not require high mechanical properties. What needed attention was the hoop per...
