Abstract
The present invention relates to one kind of environment protecting non-toxic ship antifouling technology. Unlike traditional method, which adopts paint with solvent for antifouling and anticorrosion, the present invention prefabricates antifouling and anticorrosion layer and covers the prefabricated antifouling and anticorrosion layer onto ship shell by means of hyperacoustic frequency induced heating technology to form the protecting layer. The prefabricated antifouling and anticorrosion layer is made of polyethylene with ultrahigh molecular weight and functional nano material, and has the features of high wear resistance, high toughness, low surface energy, etc.
Description
Technical field:
The present invention relates to the antifouling corrosion protection technology that a kind of naval vessel adds sheath, belong to International Classification of Patents B29C63/00 " lining or add protect " and C08F255/02 " monomer is received the high molecular compound that obtains on the olefin polymer " technical field.
Background technology:
21 century is the century that human development utilizes the ocean.The shipbuilding shipping, will there be great development in fields such as exploitation of offshore oil and gas and sea-farming and fishery.But various marine life such as barnacle, marine rainbow, marine alga, limestone are attached on hull bottom and the various underwater facility.Fast exploitation to human ocean with the speed of growth more than its quantity has caused great harm.
Seabed attaching organism very harmful because they not only significantly increase hull weight (on average can reach 20Kg/m), influences the speed of a ship or plane, increases consumption of fuel, causes the hull corrosion simultaneously, and ship performance descends, and increases the maintenance times that lies up.
The ship pollution prevention corrosion protection is to be accompanied by huge economic interests, and relates to the eternal lasting matter of fundamental importance of protecting the marine environment.
Summary of the invention:
Purpose of the present invention provides a kind of application superaudio electromagnetic induction plane heater, in the heating of the steel plate top layer of naval vessel shell, with the High molecular material cladding its go up and formation to the non-coating type ship pollution prevention of the environment-protecting asepsis of hull protection technology.
Technical scheme of the present invention is as follows.
The non-coating type ship pollution prevention of a kind of environment-protecting asepsis technology, it is to use superaudio plane electromagnetic induction heater, be covered with in illiteracy and adopt outer scanning to heat on the naval vessel iron and steel shell of Polymer coiled material, by the Fu rolling device with the compacting of Polymer coiled material on the steel plate that is heated, need make the temperature of steel plate surpass the melt temperature of High molecular material, together with the steel plate cladding of Polymer coiled material and naval vessel shell.
Described Polymer coiled material is preferably the ultra-high molecular weight polyethylene coiled material.
The temperature that described shell scans heating outward is controlled at 250 ℃--and 300 ℃.
Seam between the Polymer coiled material leaves overlap joint mouthful, is added with steel band, the overlap joint material welding that utilizes the superaudio electromagnetic induction heating technology to make to contain steel band in overlap joint mouthful.
The technology of the present invention is changed ship pollution prevention with the traditional prefabricated High molecular material stain-proofing layer of coating, use superaudio electromagnetic induction technology with its cladding on naval vessel shell steel plate.Utilize high abrasion, high strength, high tenacity, the low-surface-energy of High molecular material, make marine life be difficult for adhering to,, have stainedly slightly, also can not cover the jail, be easy to dispose even the time of berthing is long.
Description of drawings:
Fig. 1 be in the non-coating type ship pollution prevention of the environment-protecting asepsis of the present invention technology between the Polymer coiled material seam leave the overlap joint mouthful scheme drawing.
Fig. 2, Fig. 3 respectively different samples draw back experimental data figure for what Tsing-Hua University did.
Among the figure: 1, antifouling coiled material A, 2, the steel band that is heated, 3, naval vessel shell steel plate, 4, antifouling coiled material B.
The specific embodiment:
The technology of the present invention is used 10KW power, frequency is the plane electromagnetic heater of 8KHZ, on the naval vessel shell, cover and covered Polymer web exterior surface scanning heating, make the steel plate outside face be warmed up to 250-300 ℃, the moving rolling wheel with the plane electromagnetic induction heater is compacted to the Polymer coiled material on the surface of hot steel plate.Because steel billet temperature has surpassed the melt temperature of High molecular material, makes the Polymer coiled material paste the rapid fusion of one side of steel plate, adheres to each other with steel plate.Adhere to intensity of force after the cooling and reach 8MPA/cm, be higher than the highest boot topping paint 2.948MPA/cm of marine paint adhesive ability.Can see the observed data that draws back that Tsing-Hua University does for details.
The Polymer coiled material be subjected to high when hot mol wt can decrease, but because the steel plate heat absorption is fast, cooling rapidly, and the outside face of Polymer coiled material is unaffected, still keeps original degree of finish and every performance figure, realizes designing requirement.
Referring to accompanying drawing 1: Polymer coiled material side leaves overlap joint mouthful, be added with steel hollow out band in the overlap joint mouth, high-frequency heating makes two coiled material sides contain steel band and is welded together, the intensity of its connection surpasses the cohesive failure intensity of material, so can be with the protective layer of the whole cladding last layer of naval vessel shell High molecular material.
Because this High molecular material is to add the function nano material by ultra-high molecular weight polyethylene (UHMWPE) to make, and makes this material when having kept original excellent specific property, has increased the long acting antibiotic function again, and lower surface energy.Make marine life more be difficult for adhering to.Adopt this non-coating type ship pollution prevention technology can solve the Three Difficult Issues of ship pollution prevention:
1, environment-protecting asepsis: original organotin self polishing copolymer antifouling paint relies on the continuous toxin expelling in ocean, and restrain marine life and adhere to, meeting gross pollution seawater, toxin can be enriched in the halobiontic body, finally can enter human food chain, can leave a legacy of trouble to the descendants.
In forbidding on January 1st, 2003, the tin-free self-polishing anti fouling paint of low toxicity finally also can ban use of the organotin self polishing copolymer antifouling paint.
And the prefabricated Polymer stain-proofing layer of present technique is the High molecular material that can directly touch food, and the ocean is had no pollution.The present technique construction technology is the hot melt coating process, does not more have the paint solvent contaminated environment.
2, overweight corrosion: what present technique was used is prefabricated Polymer anti-fouling material, and material thickness can artificially be controlled, and promptly stain-proofing layer thickness can be selected in the 3-6 millimeter.And paint coatings not only has the solvent evaporates pin hole to corrode easily, and will repeatedly spray and also reach overweight corrosion protection standard 1000 μ m, and adopts the stain-proofing layer of the technology of the present invention preparation once can reach thousands of μ m.
3, antifouling life is long: material guarantor in Wuhan translates in " fusion techniques " literary composition and introduces: the basic jetty type wharf of the Yangtze Bridge, the durable years of iron structure things such as unrestrained dike requires to reach more than 40 years, and the corrosion protection overplate of its long-term nothing maintenance of polyethylene effect is very noticeable.
Below only be reference, in fact, the short of mechanical damage of Polymer protective layer of 5-6 millimeters thick, tenure of use should be more than 20 years.
