Description
Technical field
Anti- shell adhesive coating material
Technical background
Ship through the navigation of long duration or stay pool after, can be tied on its water line ship outer casing below full barnacle or with
Its marine growth and the dirty layer of life.Because dirt layer covering is in comprehensively and again super coarse touching water termination, the resistance of hull is directly resulted in
Increase, causes that the speed of a ship or plane slows down or fuel consumption significantly increases.Shell adherency be since the dawn of human civilization influence navigation economic benefit be difficult to resolve it is stupid
Disease.Report according to open source information, USN: additional fuel disappears caused by a medium scale destroyer is adhered to because of shellfish every year
Consume and remove about 62,000,000 dollars of expense with coating.In order to eliminate the adherency of shell, industry experts are once used over the years: electricity
Striking, poisoning method, the removing method cleared up etc. into dock method of cleaning and underwater robot, but all accordingly have: completeness,
All kinds of shortcomings of restricted, economy and applicability.
Abroad in Recent Years is the study found that a kind of drug for clinical anesthesia: Medetomidine (Medetomidine) can
So that barnacle is fled from.Gothenburg, Sweden university research personnel, Medetomidine is fitted into organic glass Caplet, then by Caplet
It mixes in ship paint, the adherency of shellfish is expelled in a manner of slow release.Japan leads over world's research and development and adds in marine paint
The new material of propylene and silicon etc., and the working substance etc. for inhibiting adherency is extracted from marine organisms.
It could be said that crack shell adherency chronic disease, be the mankind never have abandon seek.
Summary of the invention
In order to explore the novel means for cracking shell adherency, a kind of method for inventing nontoxic anti-barnacle adherency.This method can
Referred to as: inhibiting adhesion method.Its principle is, on the existing lacquer painting of shell, then brushes one layer of coating containing antibacterial substance, works as shellfish
Class is moved away from when adsorbing shell since the thorn effect of hitting by antibacterial substance causes shellfish voluntarily to evade.The antibacterial substance, be it is a kind of both
It is edible addition again can compatibility be used as medicine mine biomass, Chinese medicinal material --- alum.
Alum, also known as alum, arcanite etc., main chemical compositions are 12 hydrazine aluminum sulfate potassium.Alum is pharmacologically having suppression
The effect of bacterium, desinsection.It is non-to inhibiting barnacle to be stained in coating that the test for launching test specimen through preliminary ocean shows that alum is added
Normal significant effect.And do not find the substance to the harmful adverse reaction of fish.(being detailed in rear adhesion test overview)
The quasi- method of this case is:, to inhibit adhesive attraction substance, to be equipped with two kinds of colloid materials of different nature from alum
The coating that amphitypy rationality is different, and the identical anti-shellfish of effect adheres to is made in (acrylic acid, natural rubber).By the type coating application
In all touching sealing waxes face of hull underwater, the active layer being respectively completely closed is formed.In order to make the action period of anti-adhesive extremely
Less up to 3 years or more, active layer will have the corresponding thickness of resistance to consumption.
In the type coating, the added material for playing bacteriostasis is two kinds: one is alum fine powder foams, and one is alum balls
Shape little particle.Wherein fine powder foam is mainly used for being tuned into the base-material of coating with colloid material mix, and has concurrently and inhibit the attached of adherency
Effect is helped, and spherical little particle is used exclusively for inhibiting the effect main body of adherency；In coating, the application purpose of base-material has two
A: 1 is the touching water termination that spherical little particle is evenly arranged on to all hull underwaters.2 be package and fixed spherical little particle, and
Spherical little particle is set slowly to degrade with base-material itself and synchronize molten, the effect being sustained with realization effect main body extension that disappears.
Colloid material: acrylic acid, non-toxic and tasteless, caking property is strong, sea water resistance and ageing resistance；Natural rubber, it is nontoxic, it is whole
Body is structural strong, not anti-aging, and has water-resisting property.The sea water resistances of two kinds of colloid materials, water-resisting property and anti-aging, all need thing
First carry out reduction modification, with reach not only be not afraid of seawater it is molten ruin but also can the Dip of seawater bubble in slowly lose molten degradation.Modified glue
The mixs such as material and compatibility material (other materials of fine powder foam, spherical little particle or non-alum), are finally modulated into the cream containing particle
Shape coating.
The type coating in application, need to repeatedly spray it is once-forming, to form the techonosphere of integraty.When the work of active layer
Limit can set effective lifetime, erosion molten and water impact abrasion of the lifetime inside courtyard in seawater according to user's requirement
Under, dissolved gradually with slowly state thinning, finalization fails to the greatest extent.
In coating, why the substance for playing subjective role is made spherical shape, and purpose has be at three: 1. to reduce to weak
Change weakening again for colloid drawknot.Spheric granules do not have sharp shape corner angle and particle and particle mutually touch to interface it is minimum, In
The honeycomb of cutting any direction will not be obstructed in setting in place in base-material through lattice.2. be spheric granules posture have realize it is slow
The mechanicalness released.Because the touching water termination of active layer is in losing molten process of extinction, exposed particle is spheric granules at first
Top surface, most sphere is also wrapped among the solid of base-material, and exposing Shi Yingyi to the open air when the maximum cross-section of sphere lasts
It is longer.3. being the harmony for being conducive to keep action intensity.Spheric granules property free to slide is strong, and level will not be formed in mix
Property orderly group column, but be in unordered free disturbance state, this unordered free disturbance state, on the constantly boundary of the molten process of erosion
On face, this state can be presented: the particle having will be idle most, the just broken shell of some particles, and some particles have consumed of half or anteposition
Grain not yet exhausts the broken shell of adjacent particle.
Spirit of the invention is: exploring a kind of new material of anti-shellfish adherency shell.
Specific embodiment
1. alum selects choosing
It is the decisive material of anti-adhesive that the effect of 1.1 alums and moral character, which require alum, and matter is to determine the type coating
The fundamental factor of practicability.Alum will select the fine work of pure cleaning, do the double refining of removing impurities purification when necessary, or directly
Change traditional refinement technique and technique is made, both realized in the case where not changing the preceding topic of alum matter, allows the purity and knot of alum
Brilliant density is promoted, and is best to approach the moral character of rock.The purpose is to: there is the water-soluble speed of alum and significantly prolongs
It is slow, to realize that the solution rate of particle reaches synchronous with the wear and tear speed of base-material；Existing it technique is made can not realize if changing
When, it is contemplated that it is synthesized in the case where guaranteeing alum matter as far as possible with other materials, to realize alum liter at certain slightly solubility.
The preparation processing of 1.2 alums first crushes blocky alum, screened its two grades of screening object that selects: one grade is fine powder
Foam.Two grades are partial size 2-3mm disintegrating slag.For one grade of fine powder foam again through levigate, fineness is not more than 200 mesh.Two grades of disintegrating slag is through special
It is ground into spherical little particle with equipment, spherical short grained partial size is 1.5--2mm.Particle less than 1.5mm greater than 2mm is not
Preferably select.
2. the selection and modification of acrylic acid, natural rubber
2.1 acrylic acids and natural rubber using emulsus stoste acrylic acid and natural rubber have respectively good sea water resistance,
Water-resisting property and anti-aging and not ageing resistance, but this kind of property cannot achieve gradually degradation and disappear molten technical purpose, and this is just needed
Alum fine powder foam is added in virgin rubber or other (such as quartz sand powder) fillers are modified it, and the modified technical indicator of sizing material is:
1. guaranteeing that configuration is not fallen off without abnormal within the useful life phase of active layer.2. the time delay for losing molten recession will be grown, with not
Lower than 3 years or without departing from 5 years targets were suitable.
The synthetic material that 2.2 coating modulate coating is only two kinds: finished product base-material, spherical little particle.It matches share: with
Realize that the density that 3--4 are no less than in the plane of 10 X 10mm is advisable.Coating will have certain consistency, can through n times brushing
Certain thickness active layer is constituted, to extend the validity period of active layer.
3. the application of coating
The 3.1 brushing work opportunities type coating is molten intentional because there is degradation to disappear, that is to say, that the attachment time limit of the type coating
About 3-4 at most would not be more than 5 years, so cannot replace the corrosion-inhibiting coating of shell routine, only be completed in shell lacquer painting
Carry out covering brushing again afterwards.
The applicability of 3.2 coating, which measures type coating sizing, will carry out carry out accordance with the paint kind of site operation of all kinds of shells after
Measurement on the spot, if having situation about cannot be suitble to, also need it is mating research and development neutral transition matchmaker's property interfacial agents.
Test overview about the anti-barnacle adherency of discovery alum
This time test is only conceptual exploratory experiment, and test objective is four aspects: whether 1. alums have inhibition shellfish
The effect .2. coating of class absorption is added after alum whether there are also water resistance .3. shellfishes to adsorb to not particularly with the addition of when measuring more
Otherness of the coating of same color either with or without selection.4. alum is to the whether toxic property of fish.
Test material: alum (medicinal material for taking pharmacy) is ground into powder shape by hand.Coating is the common exterior coating of engineering
(same brand, reddish brown, sea blue dichromatism, acrylic acid sizing material) test specimen is the band-like lath of stainless steel
Test process is as follows:
1. test specimen release position is similar to same condition (seawater simultaneously flows) of ship's navigation
Test sea area is the Bohai Sea.Place is that Tangshan City Fengnan District is black along sub- seashore, and the pumping plant of seawater is extracted in former Fengnan saltern
Sluice gate.The pumping plant sluice gate and sea are straight-through, and it is that around the clock, the seawater overcurrent of sluice gate is also therewith that pumping plant, which extracts seawater most time,
There is stream to have and stops.
2. the test specimen body and underwater penetration launched
Test specimen is 1mm thickness stainless steel banding sheet material, long 1400mm, wide 110mm.Band-like test specimen be vertically put into the sluice gate water surface with
Lower about 500mm.
3. the addition compatibility amount and sample section brushing of test specimen coating
The dosage of the coating addition alum powder of two kinds of colors is respectively third gear, every grade of additive amount etc., coating and alum
Ratio: one grade about 10: 0.2, two grades about 10: 5, every grade of third gear about 10: 1. is each to brush one section, segment length about 300mm, section and section it
Between have about 20---30mm sky every the clear band of about 100mm is stayed in the end of strip one end
Alum powder is not that too carefully, through window screening screening, deliberately there are be by steel before some tiny disintegrating slag coating applications
Blackboard eraser wiping dust, does not make any base treatment, every section twice of each brush.
4. test specimen launches the period
--- -- the late October of in early March, 2013 about nearly 7 months Fertilizing stage
5. test result
5.1 alums, clearly all bare metal faces for there be not swabbing are (empty every, blank for the function and effect of anti-barnacle adherency
Section), barnacle has become saturated with and tightly.Then one grade of section sticks substantially but the more sparse third gear section of bis- grades of sections of sparse only has two or three
It is a, and head is smaller；Except, it is empty every, clear band and one, two, three shelves coating sample section, do not find separately there are other marine growths
Adherency.
5.2 1, two, two tinctorial pattern sections of third gear are showed no coating and have and lose the molten or that falls off
The number density indifference .. of 5.3 reddish brown, sea blue two kinds of colors and barnacle absorption
The test specimen that the toxicity of 5.4 alums verifies this time is a formula two pieces, a throwing sea, an investment family fish jar fish jar
Long 1800mm, wide 600mm, depth of water 640mm, about 690kg fresh water (containing about 150 grams of salt in fish jar), fingerling was ornamental value gold carp,
Wherein big fish two is about 220mm, and small fish 17 are about the test specimens of 40---60mm. investment fish jar and throw on the same day of the extra large test specimen same period
Water had not been changed in addition to therebetween except daily from closed loop
The shoal of fish participated in the experiment at that time also exists, though as long as having lasted 6 years, it is showed no exception up to now, and have and grow up.
