Abstract
A wear-proof and high-temperature-resistant ceramic coating is a high-temperature-resistant, wear-proof and energy-saving industrial coating used for metal and prepared from an inorganic modified solution and nano inorganic ceramic filler. The coating can provide a wear-proof, anti-impact, high-adhesion, anticorrosion and tough protecting coating for equipment, is good in compactness and high in permeability resistance, has the capability of working for a long time under severe conditions and can be used for a long time in oilfield wastewater and corrosive media such as acid, alkaline, salt and the like; meanwhile, the coating doesn't pollute the environment, is inorganic, green and environment-friendly and can be widely applied to the fields of metallurgy, petrochemical engineering, the cement industry, natural gas extraction and even aerospace aviation.
Description
Technical field
Wear-resistant, high-temperature resistant ceramic coating is that heatproof can reach 1200 DEG C, and intensity can reach 150Mpa, and antiseptic property is excellent, has the several functions such as abrasion-resistant and heat resistant and wear resistant protective system all over the body.
Background technology
In the production process of metallurgy, electric power, chemical engineering industry, under much equipment, pipeline are in severe working order for a long time, particularly the Working environment of the superheater tube of thermal power plant boiler, reheater tube, water cooling tube, economizer tube (being commonly called as " four pipes ") is very severe.Such as: in boiler, temperature is up to 1200 DEG C, accompany 8 ~ 16 object solid particulates of 30% in high-temperature gas, flow velocity is about 10m/s.For preventing the synergy of tube wall high temperature oxidation and wearing and tearing, the measure generally adopted at present is: outside tube wall, add a cover metal wearing-resistant tile or at metallic conduit external pasting wear resistant ceramic chip.The complicated construction technique of these methods, cost is high, and effect is not ideal again.If spread high temperature resistant, the anti abrasive ceramic coating of one deck in metallic surface, then the effective way addressed this problem of can yet be regarded as.
Summary of the invention
Wearable ceramic coat is a kind of nonmetal gelling material, and it is a kind of powdered ceramic material adopting acidproof and alkaline-resisting artificial-synthetic material to make through strict processing compound and advanced inorganic polymeric technology.At the construction field (site), special liquid inorganic glue water is added this material, artificial or mechanical system is adopted to spread upon equipment liner or surface, through a series of chemical reaction, bonding strength and the hardness of pottery is reached after 3 days, therefore named wearable ceramic coat under normal temperature air relative humidity is less than 60% situation.
The nano inorganic ceramic powder that heat resistant and wear resistant ceramic coating adopts the distinctive inorganic modified solution of will Sheng Weihua company different with particle diameter, precision work forms, and coating has the complex function such as anticorrosion, wear-resisting, high temperature resistant shock resistance and good snappiness.Coating filmogen is the backbone containing hydroxyl, is beneficial to the dispersion of pigment and solidification and coating after making solidification has good snappiness and shock resistance, and the inorganic fibre in coating can ensure the shock resistance of coating further.And the ceramic functional stuffing of will Sheng Hua prestige company heat-resisting antiwear paint various ingredients composition, mutually collaboratively impart that coating is wear-resisting, antiseptic property, and enhance coating adhesion, overcome the internal stress produced because of paint solidification volumetric shrinkage.Will Sheng Weihua scientific research personnel is according in the experiment of up to ten thousand times, find to add UV light absorber at paint filler, the weathering resistance of coating can be substantially increased, extend the work-ing life of coating, add ultra-violet radiation resisting material in high temperature abrasion material, as finish paint in atmospheric environment because nano material particle diameter is little, different absorptions, reflection, scattering process can be produced to the light of different wave length, significantly improve the ultraviolet-absorbing of coating, thus improve the weathering resistance of film.Can be used in the surfaces such as iron, steel, aluminium, pottery, in such as metallurgy, petrochemical complex, electric power, medicine, Natural gas extraction, the industrial circles such as aerospace are extensively suitable for.
Wear-resistant, high-temperature resistant ceramic coating feature is:
1. Wear-resistant, high-temperature resistant ceramic coating has high physical strength and rigidity: Ceramic abrasion-resistant paint is primarily of abrasive aggregates and coupling system composition, density is very large, without large macroscopic defects, intensity can reach 130Mpa, is that general concrete and refractory castable are incomparable.2. Wear-resistant, high-temperature resistant ceramic coating has excellent toughness and shock resistance: because ceramic wear-resisting material adopts omnidirectional firm fiber and the netted enhancement measures of orientation, toughness is improved further by being coupled, so fracture toughness property is strong, the breakage that can effectively prevent surging force from causing and peeling off.3. Wear-resistant, high-temperature resistant ceramic coating good integrity: because wearable ceramic coat takes dual reinforcement measure, what have even takes multiple reinforcement measure, effectively improves material property.And the coefficient of expansion etc. that stupalith is low, make its volume stability, can not crack be produced, thus good integrity, construction is integral construction in addition, occurs without seam, thus globality improves further, and heatproof can reach 1200 DEG C, and ultimate temperature can reach 1250 DEG C.4. Wear-resistant, high-temperature resistant ceramic coating Environmental compatibility is good: owing to have employed acidproof and alkaline-resisting artificial-synthetic material, can not react with slag, simultaneously because this material mostly is high―temperature nuclei raw material, crystal development is good, structural integrity, envrionment temperature can not cause large impact to it, belongs to environment inert material, thus poor to environmental sensitivity.5. Wear-resistant, high-temperature resistant ceramic coating non-environmental-pollution: mill ceramic coating is ceramic, major ingredient is silicate, close with earth's lithosphere composition, and soil property can not be caused to worsen and heavy-metal pollution, can not influence ecological environment, be a kind of product of environmental type.
Wear-resistant, high-temperature resistant ceramic coating performance is for shown in following table:
Accompanying drawing explanation
Fig. 1 is the proportioning raw materials of Wear-resistant, high-temperature resistant ceramic coating.
