Accordingly, the fuel can be mixed with air more conveniently, combustion of the fuel is more sufficient, content of harmful gases in waste gas is decreased, combustion value of the fuel is increased, and the purposes of fuel economization and emission reduction are achieved.
Description
Technical field
The utility model relates to automotive oil tank, particularly a kind of six layers of co-extrusion functional form blowing automobile plastic fuel tank.This fuel tank not only has high obstructing performance to gasoline, and has the oil-saving discharging-reducing effect.
Background technology
Along with plastics are widely applied automotive oil tank and are also developed into plastic fuel tank by original metal fuel tank on automobile.Why plastic fuel tank can be widely used on the automobile, mainly is that plastic fuel tank has many metal fuel tank parts that is better than, such as, freedom of design in configuration is big, the production efficiency height, and cost is low, and is good in economic efficiency; In light weight, corrosion-resistant, shock-resistant, intensity is good; Do not set off an explosion endurance quality excellence etc. during burning.
Existing plastic fuel tank has two types substantially: a kind of is that molecular weight is 50 ~ 800,000 polyethylene, and through the plastic fuel tank of the single layer structure of blow molding, its cabinet wall carries out the surface treatment of distinct methods, to improve the seepage of its fire resistant oil.Another kind is to be base material with the ultra high molecular weight polyethylene, be aided with barrier material or adhesives, the individual layer of blow molding preparation and the plastic fuel tank of multi-layer compound structure (referring to author Yan Faqing in 1999 the 5th phases of " automotive research and exploitation " magazine, paper---" application and the development trend of plastic fuel tank in auto industry " delivered on the 36th ~ 43 page).
Because it is fuel tank belongs to the vitals of automobile oil, therefore higher to shock-resistant, anti-leakage, performance requirement such as fire-retardant, explosion-proof.In addition, the world today, petroleum resources are day by day nervous, and fuel price is high, and the discharge capacity of dusty gas such as consequent carbon dioxide constantly increases on the other hand.At present countries in the world government is all vigorously advocating energy-conserving and environment-protective, complies with this trend, numerous scientific research personnel watching in the research and development of fuel-saving environmental protection product and method.Therefore, the automobile plastic fuel tank that how to design a kind of excellent performance and have an oil-saving discharging-reducing effect is the problem of the utility model research.
Summary of the invention
The utility model provides a kind of six layers of co-extrusion functional form blowing automobile plastic fuel tank, its objective is the automobile plastic fuel tank of wanting a kind of excellent performance and having the oil-saving discharging-reducing effect.
For achieving the above object, the technical solution adopted in the utility model is: a kind of six layers of co-extrusion functional form blowing automobile plastic fuel tank, it is characterized in that: the tank wall of described fuel tank constitutes by six layer materials are compound, and this six layer material is respectively basic unit, first adhesive layer, functional layer, second adhesive layer, enhancement Layer and decorative layer from inside to outside.
The utility model operation principle is: various fuel oils are the hydrocarbon of different molecular weight, are generally that carbon atom and hydrogen atom rely on valence link and the alkanes molecule that is combined into.And the covalent bond of hydrogen atom and carbon atom makes molecule become polar molecule.Electrostatic attraction by means of dipole moment between the molecule is combined into macromolecular mass, and this power is called Van der Waals force, therefore forms macromolecular mass, has influenced the abundant burning of fuel oil.Oil molecule is in the molecular aggregates state usually under the effect of Van der Waals force, can not fully burn, and especially to contain molecule many for the coherent condition micel of gasoline.And the utility model adds functional material in basic unit and functional layer, makes the function of the existing storage of fuels oil of fuel tank, and stronger oil-saving discharging-reducing effect is arranged again, and promptly six layers of co-extrusion functional form blowing automobile plastic fuel tank also are large-scale powerful gasoline economizers.This six layers of coextrusion blow automobile plastic fuel tank utilize far infrared and the anion ray that functional material sends in fuel tank basic unit and the functional layer to directly act on fuel oil at the storage fuel oil simultaneously, fuel molecule is under functional actinism, Van der Waals force between the oil molecule destroys, forming the long-chain formula arranges in order, become " short chain " by " long-chain " again, even individual molecule, make intermolecular average distance increase, fuel oil concentration descends fast, the mobile raising, especially atomization significantly improves, thereby be more convenient for and Air mixing, make burning more abundant, reduced content of harmful gas in the waste gas, improved the fuel value of fuel oil, reached fuel-economizing and reduce discharging purpose.
Because the technique scheme utilization, the utility model compared with prior art has following advantage and effect:
1. existing intensity preferably of the utility model functional form fuel tank and barrier property itself are again large-scale gasoline economizers, have stronger oil-saving discharging-reducing effect, and its fuel-economizing effect is greater than common gasoline economizer.
2. the utility model is owing to added functional material in basic unit and functional layer, far infrared that this functional material sends and anion ray can be directly, long-time and fuel oil is fully had an effect, make fuel molecule group scintillaization, oil molecule in the catalysis fuel oil, improved the effect of activation of fuel oil, help fuel oil and fully burn, improved fuel-saving efficiency.
3. the utility model functional form fuel tank rocking in running car can impel fuel oil and far infrared and anion fully to have an effect, thereby further improved oil-saving effect.
4. the utility model is combined into one intensity, barrier property and oil-saving discharging-reducing three dexterously at the characteristics of automotive oil tank, compared with prior art has the substantive distinguishing features that goes out in fact.
