Description
Technical field
The present invention relates to a kind of metal cleaner, particularly a kind of metallic bearing water-based clean-out system and method for making and application.
Background technology
Bearing has very high requirement as a kind of precise part to its vibration values and noise, and the bearing ring channel precision is high, all can have a strong impact on bearing vibration and noise even atomic little impurity is stayed in the raceway groove, so require very high to bearing cleaning process.Especially the finished product bearing after the trap, owing to assembled retainer and rolling body, the lasso raceway groove is enclosed in the bearing bore, raceway groove is easy cleaning not, in case it is cleaning dirty then need tear cover open, not only time-consuming, effort also will be damaged retainer and rolling body, therefore for finished product bearing cleaning medium strict demand are arranged.
Clean for the finished product bearing after the trap, still adopt kerosene or gasoline medium to clean at present in the bearing industry.Kerosene and gasoline all are volatile, incendive organic hydrocarbon materials, constitute great potential safety hazard in cleaning process, also have a strong impact on operator's health simultaneously; In today of energy worsening shortages, Production of bearing enterprise still uses kerosene, gasoline as the bearing clean-out system, will inevitably cause the significant wastage of the energy, increases problems such as enterprise's production cost and environmental pollution.
Though some Production of bearing enterprise has adopted aqueous cleaning agent to clean in the cleaning of bearing parts at present, the still unmanned aqueous cleaning agent that uses in the finished product bearing cleaning process after trap.
Clean for bearing parts, the aqueous cleaning agent that uses in the bearing industry all is to use yellow soda ash as alkali source at present, and phosphoric acid salt is as water-softening chemicals, and Sodium Nitrite is as rust inhibitor.Though these chemical feedstockss are soluble in water, yellow soda ash can generate precipitation with calcium ions and magnesium ions reaction in the water, reduces cleaning performance; And phosphoric acid salt can cause the water quality eutrophication as water-softening chemicals after the discharging, contaminate environment, and pungency is stronger; Sodium Nitrite remains in the formation solid crystal thing of component surface after the water volatilization, remove difficulty.Because these compositions all can need rinsing completely to remove at bearing surface production impurity in various degree after the water volatilization at last; And bearing is the integral body that is assembled by each component, the position that exists raceway groove and can't see, and small particle all can influence the quality of product; Consider the material of bearing, as Cr
3+Can influence the result of use of some tensio-active agent, even produce precipitation, so this class aqueous cleaning agent is not suitable as the special purpose detergent of bearing products.
Thereby need a kind of cleaning back noresidue on bearing parts, need not the aqueous cleaning agent of post rinse.
Summary of the invention
Technical problem to be solved by this invention provides a kind of metallic bearing water-based clean-out system and method for making and application.The metallic bearing water-based clean-out system of preparation can substitute gasoline, kerosene and general aqueous cleaning agent, and raw materials used being easy to get is cheap for manufacturing cost; In order to bearing cleaning and bearing spare and accessory parts, remain in the thoroughly rinsing of chemical substance of component after the volatilization of the water of clean-out system, can satisfy the requirement of assembling.
