4.6 external structure layer 5: this layer is mainly that its thickness is 20% of main structure layer for the main structure layer provides necessary guarantee; The laying method is identical with the main structure layer; Solidify rear removal burr fully until it standby.
4.7 external anti-corrosion layer 6: after structure sheaf solidifies the removal burr fully outside, grace is coated with the vinylite of the anticorrosion heatproof of last layer, and according to following program laying: chopped felt 300-04 glass cloth-chopped felt 450(300)-04 glass cloth-chopped felt 300(450), make its thickness reach 1.5mm; After solidifying fully, band removes burr standby.
4.8 reinforcement 8: the 8 meters needs design reinforcements of generally often being separated by, reinforcement can adopt polyurethane foam by trapezoidal cutting and be compounded on product surface, also can adopt fibre glass product manufacture that mould production meets product external surfaces fully as reinforcement, reinforcement should polish product surface the bar shaped of 300mm at least before being fixed on product surface; Then adopt the laying of chopped felt 300-04 glass cloth-chopped felt 300-04 glass cloth to lay more than 3 times, every layer all needs the upper strata is covered fully, removes burring machine after the band reinforcement solidifies fully and carries out further work.
4.9 outer surface layer (being outside surface anticorrosion heat-resistant layer 7): the vinyl epoxy resin of employing flame retardant type heat-resisting and anticorrosive sprays the external anti-corrosion layer of completion of cure one time, presses following program laying: chopped felt 300-composite felt 150G-04 glass cloth-chopped felt 300.Can use polyester film that product is covered or adopt vinylite fully after completing: the ratio of paraffin solution=100:15 modulation vinylite paraffin solution, and be sprayed on and get final product spontaneous curing on product.The general polyester film that adopts covers in the resistant to elevated temperatures situation of needs.
5, the demoulding and finishing
After solidifying fully, product carries out the demoulding; Use hydraulic ingot stripper to withstand the product reinforcement and get final product the demoulding.If connect in product needed program afterwards, must be before the demoulding grinding to be carried out at product two ends and processed, grinding need to be carried out the tapering grinding.
6, the connection of product and installation
Composite material conduit can be applicable in the Related products such as flue and chimney, product needs to use elbow and threeway etc. in installation, bonding after product cutting need to be become elbow or threeway, cutting suits also can simulate in computer according to intersecting lens and obtains suiting after corresponding data or adopting the cutting of corresponding frock; To need the two ends that bond by the tapering 300mm that polishes after cutting, adopt the laying method identical with laying in production, and after cutting into corresponding size by identical raw material, press same process step laying and solidify and get final product, and spray yarn and can use 300 chopped felts replacements.
The installation of product, after using crane that product component is lifted into the relevant position, the method connection bonding that A is pressed in the coupling part gets final product, and processes too at the product inner surface, uses clay to clog and solidify at seam crossing and gets final product.
7, the maintenance of product
Composite flue or chimney can not bear high temperature for a long time, therefore in use generally be only applicable to the discharging of the wet flue gas after flue gas desulfurization, being operated in below 100 degrees centigrade of general composite flue or chimney, adopting new techniques can make the operating temperature of composite flue or chimney reach 160 degrees centigrade, the short-term tolerance temperature reaches 400 degrees centigrade (2 hours), 260 degrees centigrade (4 hours) cause high-temperature flue gas directly to obtain buffer time by composite flue or smoke stack emission in a single day temperature appears in flue gas desulphurization system; But composite can not tolerate long high temperature after all, in use must monitor at any time the flue-gas temperature by flue Hu or chimney, avoids occurring the situation of long-time high temperature, reduces the service life of composite flue or chimney.
The advantage of composite chimney of the present invention is as follows:
1, adopt Anti-corrosion glass fiber and corrosion-resistant vinyl epoxy resin laminating production, and field fabrication, cost is moderate; Corrosion resistance is good;
2, product weight is lower, and transportation and installation cost are lower;
