Description
Technical field
The invention belongs to hardware manufacturing industry technical field, be specifically related to a kind of aqueous cleaning agent of aluminium surface.
Background technology
Cleaning refers to the liquid and solid pollutant of removing workpiece surface, makes the cleanliness factor that workpiece surface reaches certain.Cleaning is also one very important middle aided process in heat treatment production process.Allly to add through machine, workpiece before thermal treatment all should carry out.Otherwise the greasy dirt etc. on the forward and backward workpiece surface of thermal treatment directly enters heating volatilization and burning in stove, and easily cause workshop air to pollute, workpieces surface condition is also bad, even affects thermal treatment quality, particularly to thermo-chemical treatment and vacuum heat treatment.Cleaning can improve treatment production efficiency and thermal treatment quality, the environmental protection relevant with thermal treatment, and cleaning belongs to clean heat treatment category.
The preparation of so-called aqueous cleaning agent is that main component adds that auxiliary agent or other additives form with tensio-active agent, has the goods of cleaning performance.Aqueous cleaning agent cleaning removes metallic surface dirt cleaning process (or method) with the aqueous solution of aqueous cleaning agent, is called for short water solvent cleaning.Greasy dirt is often referred to mineral oil, the general liquid pollutant of animals and plants wet goods or organic semi-solid dirt.Dirt, is often referred to insoluble or solid dirt, as carbon deposit, oil mark etc.Degree of cleaning, refer to cleaning medium the oily waste degradation of metallic surface to the state of to a certain degree rear surface.
China's industry cleaning link still uses aqueous cleaning agent by the hydrocarbon mixtures such as gasoline and part at present.Not only waste energy in a large number with hydrocarbon mixture clean-out systems such as gasoline, and easily there is occupational poisoning in cleaning workman, and the presence of fire because of gasoline cleaning, cause heavy economic losses and fatal accident to be common occurrence.These factors are major causes that in current industry cleaning link, water solvent cleaning is badly in need of development, so Devoting Major Efforts To Developing water solvent cleaning technology, have wide prospect in China.
Aluminium density is little, although matter is soft, can be made into alloy, so be widely used in the production such as aircraft, boats and ships, automobile.The electroconductibility of aluminium is also better, although electric conductivity is not as copper, aluminium conductor unit weight is light and with low cost, and the oxide film that surface is formed has certain insulativity, so be widely used in the industry such as electric apparatus manufacture, radio industry.Aluminium has the stronger capacity of heat transmission, so be made into various heat-exchange equipment, cooker etc.If accumulate in the equipment be manufactured from aluminium or attachment residual oil, reasonably clean with regard to needs.But the most alkalescence of oil-removing cleaning agent is in the past comparatively strong, and also need the condition by high temperature, such clean-out system has very large loss to resource, the energy, and easily causes security incident, causes environmental pollution.Development of new take tensio-active agent as the water system residual oil carbon steel clean-out system of main wash composition, can efficient, safety, environmental protection removing steel surface residual oil, all there is realistic meaning from the angle of economy, safety and environmental protection.
CN91109760.0, the application for a patent for invention that name is called " water-soluble metal cleaning liquor ", this scavenging solution take water as solvent, adds emulsifying agent sodium laurylsulfonate, OP-10; Rust-preventive agent sodium pentachlorophenate, Sodium Benzoate, Sodium Nitrite; Clean-out system trolamine, polyoxyethylene glycol, ethanol, phosphoric acid are formulated, and it can be used for the cleaning of various steel, cast iron product.But it is many that shortcoming is foam, and electric conductivity is low, general needs heats use.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of aqueous cleaning agent of aluminium surface.Still have stronger cleansing power at normal temperatures, not corroding metal, the easy rinsing of low bubble, soil removability is strong.
In order to realize foregoing invention object, the present invention adopts following technical scheme:
The aqueous cleaning agent on aluminium surface, is characterized in that: its composition and ratio is as follows:
Tensio-active agent KE-1 0.8-1.2 g/l
Tensio-active agent SDBS 2.0-2.5 g/l
Tensio-active agent NP-10 2.2-2.6 g/l
Washing assistant 0.5-0.6 g/l
Composite corrosion inhibitor 0.8-1 g/l
Solvent is water.
The screening and application of tensio-active agent is the key of aluminium surface water based cleaning agent.The present invention selects tensio-active agent KE-1, SDBS and NP-10 can reduce the surface tension of system, effectively can promote wetting, the infiltration of aluminium surface and oil contaminant, emulsification and dispersion, be cleaned up by aluminium surface and oil contaminant.Act on by hyperacoustic " cavitation ", by clean-out system working fluid component rapid permeability between greasy dirt and metal, greasy dirt is made to peel off rapidly aluminium surface, peel off rear surface promoting agent by grease emulsifying, under hyperacoustic effect, grease broken up and be uniformly distributed in system, improve the oil removing performance of aqueous cleaning agent highly.
On the other hand, due in the functional group of tensio-active agent KE-1, SDBS and NP-10 with multiple-limb branched structure, for the tensio-active agent of linear chain structure, its obstruction discharge opeing on liquid membrane surface and " reparation " effect reduce greatly, froth stability weakens, and after therefore bubbling, lather collapse must than comparatively fast.They are composite, good froth breaking and cleaning performance can be reached, meet the requirement of cleaning.
Preferably, described best composition and ratio is as follows:
Tensio-active agent KE-1 1.0g/l
Tensio-active agent SDBS 2.3 g/l
Tensio-active agent NP-10 2.2 g/l
Washing assistant 0.55g/l
Composite corrosion inhibitor 0.8g/l
Solvent is water.
Washing assistant of the present invention is the one or more kinds of combinations in tripoly phosphate sodium STPP, 4A zeolite and water glass.
Composite corrosion inhibitor of the present invention is that polyethylene and tetrahydroglyoxaline are composite.
Preferably, the composite mass ratio of described polyethylene and tetrahydroglyoxaline is 1:1.
Inhibiter polyethylene and tetrahydroglyoxaline are attracted to metallic surface through chemisorption process, and itself forms one deck film closely, or form one deck film closely after reacting with metal ion, therefore corrosion mitigating effect is good.When its addition is 0.6 g/l, minimum corrosion rate can reach 0.3%.
Beneficial effect of the present invention is:
1, cleansing power is strong, and under normal temperature condition, residual oil degreasing rate can reach more than 99.5%.
2, belong to low alveolitoid clean-out system, bubble up to≤5mm.
3, rustless property is good.
