Abstract
The invention relates to an organic polymer anticorrosive tank assembly including tank assembly components, wherein the tank assembly components are sprayed with a two-component organic polymer anticorrosive material on the surfaces. Through a plurality of corrosivity and fatigue performance experiments, the organic polymerization tank assembly is proved to have high impact tensile resistance and corrosion resistance strength, and excellent wear resistance and aging resistance properties.
Description
technical field
The present invention relates to the anticorrosion assembled tank of a kind of organic polymer, belong to anaerobic reaction apparatus 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 construction body well, can not guarantee the work-ing life of reactor.Therefore, in the assembled tank design process of conventional steel structure, tend to leave a part of design margin, increase the work-ing 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 corrosion protection coating life-span of welding reactor is the shortest, easily comes off, and coating shedding post-reactor is in unguarded running status, and corrosion speed is very fast.The corrosion protection coating of enamel pot is inertia enamel coating, and because of its natural characteristics, coating is more crisp, protects difficulty high in construction process, 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 big area corrosion, cannot continue to use.
Summary of the invention
The object of this invention is to provide the anticorrosion assembled tank of a kind of organic polymer, strengthened the antiseptic property of anaerobic reactor, extended its work-ing life.
For realizing above object, the anticorrosion assembled tank of a kind of organic polymer of the present invention, comprises assembled canister assembly, the two component organic polymer impregnating material of described assembled canister assembly surfaces externally and internally spraying.
Wherein, described pair of component organic polymer impregnating 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, tie-in module, special-shaped assembly, pipe joint assembly.
The beneficial effect that the present invention produces is, anticorrosion assembled tank of the present invention is comprised of the assembled canister assembly of steel and two component organic polymer impregnating material, effectively avoided because of burn into vibration, scraping, causing the phenomenon that comes off and wear and tear of anticorrosion surface layer in use or transportation, significantly extended the work-ing life of equipment, minimizing equipment use and maintenance cost, reduces Life Cycle Cost.
Embodiment
The anticorrosion assembled tank of a kind of organic polymer of the present invention, is mainly comprised of the assembled canister assembly of steel and two component organic polymer impregnating material of being sprayed on assembled canister assembly surfaces externally and internally.
Wherein assembled canister assembly comprises prefabricated steel assembly, tie-in module, 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 two component long-chain end amino polymers, comprises with the isocyanate component of NCO with NH
2amino group, described with the isocyanate component of NCO 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 physical strength and elastic fine and close polymer, there is powerful sticking power simultaneously, can be attached to treated surface of steel plate, after adhering to, through the stationary phase of certain hour, both there is powerful tension Tudor.
In table 1, provided the anticorrosion reactor of organic polymer of the present invention and common reactant device technical indicator correlation data, can find out that the assembled tank of organic polymer has high-strength shock resistance anti-tensile tensile strength and excellent protection against corrosion, wear resistance, anti-aging property.Through multinomial corrodibility and fatigability experimental verification, reach its work-ing life more than 30 years, surpass traditional enamel assembling tank and assembled tank of ECPC, the cost performance of the biogas engineering project construction greatly improving, the domestic waste, the changing food waste that are particularly suitable for building in BOT mode are processed project, chemical industry raw material storage tank, and storage sector is used.
