The thickness of the carbon fiber and glass fiber mixing needled mat ranges from 6.2 millimeters to 15.0 millimeters, and the gram weight of the carbon fiber and glass fiber mixing needled mat is 2, 000 g/m<2>. The thickness of each adhesive layer ranges from 1.2 millimeters to 2.0 millimeters. The thickness of each flame-retarding wear-resistant layer ranges from 2.5 millimeters to 3.0 millimeters. A product prepared with the preparation method has the beneficial effects of being better in corrosion resistance and flame retardance, longer in service life, moderate in cost, short in construction period and the like.
Description
Technical field
The present invention relates to a kind of corrosion-resistant lining material, be specially the preparation method of the anticorrosion FRP liner of a kind of wet desulphurization chimney.
Background technology
After coal-burning power plant adopts wet desulphurization, wet flue gas condenses and forms condensation acid solution in chimney, very strong corrosivity is produced to chimney, domestic present stage generally adopts spraying, patch block and titanium alloy inner core etc., acidproof brick is adopted easily to occur cracking, come off or acid solution seepage, adopt the ruuning situation of the sleeve-type chimney of titanium steel composite board or nickel-base alloy composite plate good, but its cost is higher.
Summary of the invention
The present invention is directed to the problems referred to above, provide the preparation method of the anticorrosion FRP liner of a kind of wet desulphurization chimney, it is better that the product that the method obtains has decay resistance, the advantages such as fire resistance is good, longer service life, and cost is moderate, and the completion time of project is short.
Technical scheme of the present invention is: the preparation method of the anticorrosion FRP liner of a kind of wet desulphurization chimney, comprise carbon fiber and glass fibre mixing Nomex, it is characterized in that: have adhesive phase at described carbon fiber with the upper and lower surface of glass fibre mixing Nomex, is fire-retardant wearing course on the surface of adhesive phase.
Described carbon fiber is 6.2 ~ 15.0 millimeters with the thickness of glass fibre mixing Nomex, grammes per square metre 2000g/m
2.
The thickness of described adhesive phase is 1.2 ~ 2.0 millimeters.
The thickness of described fire-retardant wearing course is 2.5 ~ 3.0 millimeters.
The invention has the beneficial effects as follows: the advantages such as it is better that the product that the present invention obtains has decay resistance, and fire resistance is good, longer service life, and cost is moderate, and the completion time of project is short.
Compared with prior art, tool of the present invention have the following advantages, economic effect:
1) by adding special anti-wear agent in chimney lining layer, the wearability of inner wall of stack is improved, to resist sweep of gases;
2) in inner liner fiber, adopt the carbon fiber that can conduct electricity as reinforcing material, when flue gas and inner wall of stack rub and produce electrostatic, electrostatic is transmitted to by carbon fiber and connects electric system, enters face and eliminates electrostatic dust stratification, long service life:
3) by adding fire retardant in chimney lining layer, the fire resistance of chimney is improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of product of the present invention.
In figure, 1. carbon fiber and glass fibre mixing Nomex, 2. adhesive phase, 3. fire-retardant wearing course.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the present invention is the preparation method of the anticorrosion FRP liner of a kind of wet desulphurization chimney, comprise carbon fiber and glass fibre mixing Nomex 1, it is characterized in that: have adhesive phase 2 at described carbon fiber with the upper and lower surface of glass fibre mixing Nomex 1, is fire-retardant wearing course 3 on the surface of adhesive phase 2.
Described carbon fiber is 6.2 ~ 15.0 millimeters with the thickness of glass fibre mixing Nomex 1, grammes per square metre 2000g/m
2.
The thickness of described adhesive phase 2 is 1.2 ~ 2.0 millimeters.
The thickness of described fire-retardant wearing course 3 is 2.5 ~ 3.0 millimeters.
In the present invention, carbon fiber is obtained by following operation with glass fibre mixing Nomex 1: braided glass fibre base cloth → make after the upper and lower layer of fiberglass-based cloth spreads the compound → acupuncture of carbon fiber and glass fibre → singe → press polish → thermal finalization; At the upper and lower surface spraying adhesive phase 2 of carbon fiber with glass fibre mixing Nomex 1, spray coated flame retardant wearing course 3 on the outer surface of adhesive phase 2.
Described adhesive phase 2 is obtained by following operation: the upper and lower surface → adhesive phase 2 adipic acid type polyester diol being mixed → adds catalyst dibutyltin dilaurate mix and blend → add methyl methacrylate → add titanium dioxide mix and blend → add organosiloxane → low-temperature setting water-soluble copolymer type polyurethane adhesive → be sprayed on carbon fiber and fiberglass needled mat 1 with IPDI, thickness is 1.2 millimeters.
Described fire-retardant wearing course 3 is obtained by following operation: gas atomization prepares the A1-Zn-Si-Mg-Cu-RE-Ti alloyed powder (mass percent of each composition: Al:30%, Si:4%, Zn:40.4%, RE:1.9%, Mg:1.5%, Cu:20%, Ti:2.2%) → add quantitative deionized water → add isothiazolinone corrosion inhibitor → add water-based solvent misture → add polysiloxanes dipropylene glycol monomethyl ether → add glycerine → add modified polyamide wax powder → add fire retardant three fulminuric acid ester → stirring to make it to dissolve → be sprayed on the outer surface of adhesive phase 2 → fire-retardant wearing course 3, thickness is 2.5 millimeters.
The contrast in technical performance of a kind of wet desulphurization chimney anticorrosion FRP liner and conventional liner
As can be seen here, the advantages such as it is better that the product that the present invention obtains has decay resistance, and fire resistance is good, longer service life, and cost is moderate, and the completion time of project is short.
