Abstract
The invention relates to an organosilicone-modified organic polymer corrosion-resistant spliced tank. The organosilicone-modified organic polymer corrosion-resistant spliced tank comprises a spliced tank assembly, wherein the surface of the spliced tank assembly is coated with a organosilicone-modified dual-component organic polymer. As proved by a plurality of corrosion and fatigue experiments, the organic polymer spliced tank has high impact resistance, high tensile strength, excellent corrosion resistance, wear resistance and ageing resistance.
Description
technical field
The present invention relates to the anticorrosion assembled tank of a kind of organic-silicon-modified 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 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 corrosion allowance and guarantee the service life of 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 object of this invention is to provide the anticorrosion assembled tank of a kind of organic-silicon-modified organic polymer, strengthened the antiseptic property of anaerobic reactor, extended its service life.
For realizing above object, the anticorrosion assembled tank of a kind of organic-silicon-modified organic polymer of the present invention, comprises assembled canister assembly, and described assembled canister assembly surfaces externally and internally sprays through organic-silicon-modified two component organic polymers.Described pair of component organic polymer comprises with the isocyanate component of NCO with NH
2amino group, described organosilicon is alkane hydroxyl polydimethyl diloxanes (HTPS).
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 HTPS is 1:60-100 with the mass ratio of two component organic polymers, is preferably 1:70-80.
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.
The beneficial effect that the present invention produces is, anticorrosion assembled tank of the present invention forms by the assembled canister assembly of steel with through organic-silicon-modified two component organic polymers, 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 service life of equipment, minimizing equipment use and maintenance cost, reduces Life Cycle Cost.
The specific embodiment
The anticorrosion assembled tank of a kind of organic-silicon-modified organic polymer of the present invention, mainly the assembled canister assembly of steel and the two component organic polymers through organic-silicon-modified that are sprayed on assembled canister assembly surfaces externally and internally, consist of, described organosilicon is alkane hydroxyl polydimethyl diloxanes.
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.Described HTPS is 1:60-100 with the mass ratio of two component organic polymers, is preferably 1:70-80.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, both there is powerful tension Tudor.
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.
In table 1, provided of the present inventionly through the anticorrosion reactor of organic-silicon-modified organic polymer and common reactant device technical index correlation data, can find out through the assembled tank of organic-silicon-modified organic polymer and there is high-strength shock resistance anti-tensile tensile strength and excellent corrosion prevention, resistance to abrasion, anti-aging property.Through multinomial corrosive property and fatigability experimental verification, reach its service life more than 30 years, exceed the assembled tank of traditional enamel assembling tank and 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.
Table 1. is through organic-silicon-modified organic polymer reactor and the contrast of common reactant device technical index
The index of the above-mentioned test event of table 2. and method of inspection
