Description
Technical field
The present invention relates to a kind of technique, more particularly, to a kind of anticorrosion process based on to gas station's oil tank.
Background technology
Oil is also known as crude oil, is a kind of sticky, dark brown（Sometimes a little green）Liquid.Upper crustal some areas
There is petroleum storage.It is made up of different hydrocarbon mixing, and its main constituents is alkane, is also contained in oil in addition
The elements such as sulphur, oxygen, nitrogen, phosphorus, vanadium.Oil is mainly used as fuel oil and gasoline, and fuel oil and gasoline composition are most heavy in the world
One of primary energy wanted.Oil is also the raw material of many chemical industries such as solution, chemical fertilizer, insecticide and plastics etc..Stone
Oil is mainly hydrocarbon.It is made up of different hydrocarbon mixing, and the chemical element for forming oil is mainly carbon
（83% ~ 87%）, hydrogen（11% ~ 14%）, remaining is sulphur（0.06% ~ 0.8%）, nitrogen（0.02% ~ 1.7%）, oxygen（0.08% ~
1.82%）And minor metallic element（Ni-V-Fe, antimony etc.）.The hydro carbons formed by carbon and hydrogenation conjunction forms the main of oil and formed
Part, 95% ~ 99% is accounted for, various hydro carbons are divided into by its structure：Alkane, cycloalkane, aromatic hydrocarbon.General natural oil is free of alkene
Hydrocarbon and in secondary operation product often containing quantity not wait alkene and alkynes.Sulfur-bearing, oxygen, nitrogen compound have to oil product
Evil, should try one's best removing in PETROLEUM PROCESSING.The property of oil is different because of the place of production, and density is 0.8 ~ 1.0 gram per centimeter, viscosity model
Enclose very wide, freezing point difference is very big（30 ~ -60 degrees Celsius）, boiling spread be normal temperature to more than 500 degrees Celsius, dissolve in more
Kind organic solvent, it is not soluble in water, but emulsion can be formed with water.But the composition of the oil in different oil fields and appearance can be with areas
Divide very big.Oil is mainly used as fuel oil and gasoline, fuel oil and gasoline composition at present primary energy most important in the world it
One.In gas station, oil tank is due to storage gasoline, and oil tank is embedded in ground end for a long time, and existing oil tank anti-corrosion spray technique does not reach
Mark, under the influence of ground end temperature, humidity and acid-base value etc., often results in Tank corrosion, influences the service life of oil tank.
The content of the invention
It is an object of the invention to overcome above-mentioned existing oil tank anti-corrosion spray technique not up to standard, ground end temperature, humidity with
And under the influence of acid-base value etc., often result in Tank corrosion, the problem of influenceing the service life of oil tank, devise it is a kind of based on pair plus
The anticorrosion process of petrol station oil tank, the anticorrosion process operating procedure is rigorous, can equably be applied to tank body wall so that tank body is not
Perishable, service life is longer, and it is not up to standard to solve existing oil tank anti-corrosion spray technique, in ground end temperature, humidity and soda acid
Under the influence of degree etc., Tank corrosion is often resulted in, the problem of influenceing the service life of oil tank.
The purpose of the present invention is achieved through the following technical solutions：Based on the anticorrosion process to gas station's oil tank, oil tank is prevented
Corruption metal surface is handled using derusting by sandblasting mode, the metal surface after sandblasting is cleaned so that metal surface without
Residue, the metal surface after derusting carry out Anticorrosion Construction, and its interval time is less than 8 hours, when metallic surface temperature is higher than dew
When putting 3 DEG C of the above or relative humidity more than 70%, derusting by sandblasting could be carried out, is less than 5 grades of weather conditions in rain, mist and wind-force
The construction of outdoor anticorrosion engineering can be carried out down；Anticorrosive coating using preceding stirring, in construction if there is gelling,
Phenomena such as caking, it should stop using, according to adding matched diluent in technological requirement coating, but its dosage is less than coating
The 5% of weight, structure, per pass coating layer thickness and the overlay painting interval time of corrosion-inhibiting coating should meet design requirement or product description
In regulation, if overlay painting interval exceedes the defined time, one can be carried out down after should handling coating surface and is applied
Work, coating and thickness specific requirement are as follows：One, thickness of dry film 60-80um of oil tank outer wall brushing epoxy zinc rich primer, intermediate coat
With epoxy micaceous iron corrosion resistant coating together, thickness of dry film requirement 100-150um, finish paint twice are resistance to using chlorinated rubber finish/polyurethane
Coating, every layer of 80um are waited, the total dry film layer thickness of tank wall cannot be less than 300um；Tank bottom inner surface, tank deck inner surface, in tank
The bottom of wall brushing one four sides, priming paint use epoxy zinc rich primer, and thickness of dry film requires 75um, and four times use storage tank antistatics of finish paint apply
Material, every layer of 100-150um, total thickness of dry film cannot be less than 300um, and anticorrosive paint is mutually tied using spread coating with roll coating process construction
The method of conjunction is carried out, firmly should be uniform when being constructed using spread coating, is erected after first horizontal, crisscross, plane after first facade, under
And Shangdi is constructed, when being constructed using roll coating process, roller dip should be uniform, unsuitable excessive；It is firmly unsuitable excessive during roller coating, use
Power should be uniform, and should remain a constant speed, and corner, annex etc. can not be carried out with what drum process applied using spread coating, weld seam, corner
And the corrosion-inhibiting coating at uneven surface position should focus on to brush or increase coating pass, after the completion of the construction of per pass corrosion-inhibiting coating, Ying Gen
Inspected for acceptance according to job specfication and design requirement.
In summary, the beneficial effects of the invention are as follows：The anticorrosion process operating procedure is rigorous, can equably be applied to tank
Body wall face so that tank body is not perishable, and service life is longer, and it is not up to standard to solve existing oil tank anti-corrosion spray technique, in ground end
Under the influence of temperature, humidity and acid-base value etc., Tank corrosion is often resulted in, the problem of influenceing the service life of oil tank.
