The manufacturing method of the organic polymer anticorrosive assembled tank comprises the steps that (1) sandblast derusting is carried out on assembled tank components, and rough surfaces are formed on the surfaces of the components; (2) a spraying device is used for carrying out heating melting on double-component organic polymer materials, then the melted double-component organic polymer materials are mixed and sprayed out through a high-pressure spraying gun and are sprayed on the inner surfaces and the outer surfaces of the assembled tank components; (3) after 24 hours, the strength of the materials of a polymer coating reaches the design strength, the assembled tank components are assembled, and a complete assembled tank system is formed. As verified by multiple corrosion and fatigue experiments, the organic polymer anticorrosive assembled tank has high anti-impact and anti-tensioning strength and good corrosion resistance, abrasion resistance and aging resistance.
Description
technical field
The present invention relates to the preparation method of the anticorrosion assembled tank of a kind of organic polymer, belong to anaerobic reaction equipment manufacture field.
technical background
The Anticorrosion Problems of assembled anaerobic reactor is one of subject matter of the numerous technical stafves author of puzzlement biogas industry.The anaerobic reactor overwhelming majority who uses in the world is at present steel design, and in the operational process of anaerobic reactor, traditional aseptic technic can not be protected steel structure body well, can not guarantee the service life of reactor.Therefore, in the assembled tank design process of conventional steel structure, tend to leave a part of design margin, increase the service life that corrosion allowance guarantees reactor, but the inevitable low laid down cost that increased of this part design margin, has increased the construction investment of biogas engineering.
All there is etching problem in the anaerobic reactor using in biogas industry at present, the anticorrosion coating life-span of welding reactor is the shortest, easily comes off, and coating shedding post-reactor is in unguarded running state, and corrosion rate is very fast.The anticorrosion coating of enamel pot is inertia enamel coating, and because of its inherent characteristic, coating is more crisp, protects difficulty high in work progress, and being easy to damage comes off, and after coating shedding, cannot keep its antiseptic property.ECPC coating is because of thinner thickness, and hardness is not high, also needs certain protection in installation process, if protect the improper scratch of easily damaging.When damage reaches steel surface of base, lost protective capacities, corrosion is just easy to occur at impaired loci, and is diffused as gradually large area corrosion, cannot continue to use.
Summary of the invention
The preparation method who the object of this invention is to provide the anticorrosion assembled tank of a kind of organic polymer, the anaerobic reactor that uses the method to prepare has strengthened its antiseptic property, has extended its service life.
For realizing above object, the preparation method of the anticorrosion assembled tank of a kind of organic polymer of the present invention, comprises that (1) carry out sand blasting processing by assembled canister assembly, at assembly surface, forms rough surface, is then hung on spraying hanging tool; (2) use spraying equipment that two component organic polymer anti-corrosion materials are carried out respectively to heating and melting, after then mixing by high-pressure spray gun, spray, be injected in the surfaces externally and internally of assembled canister assembly; (3) after 24 hours, polymer coated material strength reaches after design strength, and assembled canister assembly is assembled, and forms complete assembled can system, as container, uses.
Wherein, described pair of component organic polymer anti-corrosion material comprises with the isocyanate component of NCO with NH
2amino group.Described with the isocyanate component of NCO and with NH
2the mass ratio of amino group be 1:0.8-1.2, be preferably 1:1.
Wherein, described assembled canister assembly is steel assembly, and described assembled canister assembly includes but not limited to prefabricated steel assembly, coupling assembling, special-shaped assembly, pipe joint assembly.
Wherein, in described step (2), heating-up temperature is 80-95 ℃, is preferably 90 ℃.
The beneficial effect that the present invention produces is, the method of the anticorrosion assembled tank of preparation of the present invention is to adopt the solvent-free rapid hardening spraying coating process of High Temperature High Pressure after fine granularity or pulverous pair of component organic polymer anti-corrosion material mixing, to stick to equably on steel assembly, form firmly molded integral structure, prepared molding structure can keep the performance of organic polymer anti-corrosion material, make it both can bring into play the high efficiency of assembled can container, can effectively avoid again in use or transportation because of corrosion, vibration, scraping causes the phenomenon that comes off and wear and tear of anticorrosion surface layer, thereby significantly extended the service life of equipment, minimizing equipment use and maintenance cost, reduce Life Cycle Cost.
The specific embodiment
The preparation method of the anticorrosion assembled tank of a kind of organic polymer of the present invention, step is: (1) carries out sand blasting processing by the assembled canister assembly of steel, at assembly surface, forms rough surface, is then hung on spraying hanging tool; (2) use spraying equipment that two component organic polymers are carried out to heating and melting, be heated to 80-95 ℃, then by high-pressure spray gun, mix according to a certain percentage rear ejection, be injected in the surface of assembled canister assembly; (3) after 24 hours, polymer coated material strength reaches after design strength, and assembled canister assembly is assembled, and forms complete assembled can system, as container, uses.
Wherein assembled canister assembly comprises prefabricated steel assembly, coupling assembling, special-shaped assembly, pipe joint assembly etc., and said modules is assembled tank workpiece, can directly be assemblied into complete tank body.
Wherein organic polymer preservative coat material therefor is that two component long-chain end amino polymers comprise with the isocyanate component of NCO with NH
2amino group.Described with the isocyanate component of NCO and with NH
2the mass ratio of amino group be 1:0.8-1.2, be preferably 1:1.Feedstock property is powdery, can be under High Temperature High Pressure aerobic environment polymerization reaction take place fast, generation has certain mechanical strength and elastomeric fine and close polymer, there is powerful adhesive ability simultaneously, can be attached to treated surface of steel plate, after adhering to, through the stabilization period of certain hour, can there is powerful tension Tudor.
Embodiment 1:
3mm plate iron is carried out to perforate and burring processing according to design size, and after processing, steel plate bends, and according to designing requirement, bends after regulation radian, carries out sand-blast finish.After sand-blast finish, through quality inspection no problem, enter coating process.First tapping being protected, is then 1:1 by mass ratio with the isocyanate component of NCO with NH
2two kinds of raw materials of amino group carry out heating and melting, while being heated to 90 ℃, by spraying device special, be evenly sprayed on the sheet material after processing, by spraying length of the halt control thick coating in 0.8mm left and right.The sheet material that completes spraying enters and dries operation.Spraying is completed to sheet material and from tapping, hang over and dry indoorly, keep to ventilate, after 24 hours, reach 75% intensity, package spare.The sheet material packaging spare, connects with bolt by tapping in advance, and seam seals with silicone base sealant, forms whole container.The sheet material of learning from else's experience after drying is done and is corroded and senile experiment, and observed data is as follows:
