Solidifying, solidification, setting heating temperature in gelling area is 128~135 DEG C, and it is 145~155 DEG C that heating temperature, which is arranged, in curing area, is being cured
Product is heated in area continues to cure, and it is 45~50 that solidification, which reaches hardness Barcol, when ensureing depanning.
A kind of wet electrical dust precipitator FRP Wall, is made up of above-mentioned preparation method, including top panel, lower panel,
Side panel, is provided with several longitudinal rib muscle between the top panel and lower panel, the top panel, lower panel both sides pass through side panel
Connection.
Further, distance is 60~100mm between the top panel and lower panel；Distance is 880 between the side panel
~960mm.
After adopting the above scheme, compared with prior art, the present invention haing the following advantages：
With the features such as light weight, intensity is high, good flame resistance, antiseptic property is good, to improve the application range of product,
Upper alternative carbon steel wallboard+brushing glass flake corrosion-resistant structure is applied in wet electrical dust precipitator shell.
Description of the drawings
Fig. 1 is the structural schematic diagram of FRP Wall；
Label declaration
Top panel 1, lower panel 2, longitudinal rib muscle 3, side panel 4.
Specific implementation mode
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
As shown, a kind of wet electrical dust precipitator FRP Wall, including top panel 1, lower panel 2, side panel 4, on
Several longitudinal rib muscle 3 are provided between panel 1 and lower panel 2, top panel 1,2 both sides of lower panel are connected by side panel 4, top panel
Distance is 60~100mm between 1 and lower panel 2；Distance is 880~960mm between side panel 4；FRP Wall has following
Feature：
The pultrusion of FRP Wall workshop is integrally formed；3 longitudinal rib muscle 3 are set in FRP Wall, intensity is high, rigidity is high；Glass
Glass steel wallboard uses hollow structure, and air heat-insulation layer is arranged, and has heat insulating effect；FRP Wall increases fire-retardant and anti-corrosion
Raw material has strong fire-retardant and antiseptic property.
Above-mentioned FRP Wall in order to obtain is made up of following steps：
A, raw material selection resin, fibre glass roving yarn group, glass fiber composite mat；
B, yarn is sent：Fibre glass roving yarn group on creel；Creel consolidates, convenient, guide of changing yarn freely, without any
Obstacle, and can be applied in combination.
C, impregnation：The fibre glass roving yarn of uncoiling roll into a ball and glass fiber composite mat by a series of resin storage tanks, guide roller,
Pressure roller, dividing sinker screen, Extruded roller, yarn and composite felt, uniformly by resin impregnated, are matched after resin storage tank in resin storage tank slot
With guide press roller, the front and back shape of resin storage tank has a certain degree, and bending angle of the rove when passing in and out resin storage tank is made to be unlikely to
Increase tension greatly very much.
D, preforming：Yarn and composite felt soaked with resin gradually remove extra resin by preforming region, row
Bubble removing, by needed for product yarn and felt reasonably, accurately combine, it is ensured that their relative position simultaneously makes its shape
Entry shape tapered and close to shaping mould.
E, curing molding：By the metal die of heating after glass fibre resin pickup, continuous pultrusion process is divided into preheating
Area, gelling area and curing area, are heated on mold using heating plate or heating mantle, during heating, temperature is gradual for resin
It increases, viscosity reduces, and preheating zone, gelling area and curing area heating temperature are adjusted according to the variation of environment temperature, preheating zone setting
Heating temperature is 75~85 DEG C, and behind preheating zone, resin system starts gelling, solidification, and setting heating temperature in gelling area is 128
~135 DEG C, it is 145~155 DEG C that heating temperature, which is arranged, in curing area, and product is heated in curing area continues to cure, to ensure depanning
When have enough curing degrees, it is 45~50 that solidification, which reaches hardness Barcol,.
F, it draws：Dragger is the host in pultrusion molding process, has clamping and two big functions of traction, and chucking power is led
Gravitation, hauling speed be both needed to it is adjustable, hauling speed control in 0.2~0.3m/s；Using the circular saw formula diamond of standard
Saw blade has manual cutting and automatic cutting, and automatic gas cutting machine can be that the automation of pultrusion production provides safeguard, more efficient.
The temperature and mold actual temperature of operating platform display setting, can control mold temperature and pultrusion speed on platform
Degree, adjusts according to actual conditions.
