Problems solved by technology

The analysis of a large amount of data shows that so far, the methods for simultaneous recovery of nickel and phosphorus in the electroless nickel plating waste liquid are still limited. In addition, the common problems of the existing methods are that the recovered products have secondary pollution to the environment, the recovery process is complicated, and the cost is relatively high. High, it is difficult to realize the high value-added utilization of heavy metal nickel ions and phosphorus, and the recovery product of electroless nickel plating waste liquid has not been used in the field of lubricating oil additives with higher added value

example 1

[0037] Example 1: the product of the present invention is added to the gasoline internal combustion engine lubricating oil tank of a user South Korea Daewoo 2.6 displacement car in Weifang, Shandong according to the use method of the present invention. Reduce fuel consumption by 30%; internal combustion engine power is significantly enhanced; engine noise is reduced by 5.3dB; total emission of harmful gases is reduced by 43%.

example 2

[0038] Example 2: the product of the present invention is added to a factory 20m by the method of use of the present invention 3 Micro-oil screw air compressor lubricating oil and reducer lubricating oil tank, the air compressor drive motor power is 110kw, has been running continuously for 5000h. The actual measurement comparison shows that the fluid delivery volume of the air compressor can be increased by 8%; the average power consumption in the first month is reduced by 11.3%, and the average power consumption in the next two months is reduced by 8.8%; the lubricating oil change cycle is extended by more than 1 times; the mechanical noise is reduced by 4.5% dB, reducing equipment maintenance and repair costs and losses caused by downtime due to troubleshooting.

example 3

[0039] Example 3: The product of the present invention is added to the lubricating oil tank and the reducer lubricating oil tank of a certain oil pipeline large hydraulic pump according to the method of use of the present invention. The power of the hydraulic pump transmission motor is 2500kW. The actual measurement comparison of 200 hours shows that the power consumption can be reduced on average 15.5%, reduce mechanical noise by 5.5dB.

Abstract

The invention discloses a Ni-P alloy nano-powder lubricant additive prepared from nickel and phosphorus recycled from electroless nickel plating waste liquid, and a using method thereof in different friction occasions, wherein Ni-P powder is subjected to in-situ dispersion and recovered from electroless nickel plating waste liquid, dispersed again and then prepared into the lubricant additive through certain steps, together with metal chemical friction modifiers, detergent-dispersant, oxygen corrosion-resistant agents, auxiliary performance regulator, stabilizer and base oil. The lubricant additive has the advantages of good suspension stability, capability of greatly reducing equipment friction and wear, greatly reducing the frequency of equipment maintenance and parts replacement and prolonging equipment lifespan and overhaul time limit, as well as good effect of saving energy and protecting environment. The lubricant additive can be widely used in gasoline / diesel internal combustion engines, general fluid machinery, mechanical chemical sealing pieces, transmission gearboxes and other occasions, can realize the recycling of nickel and phosphorus in the electroless nickel plating waste liquid with high added value in order to change pollutants into useful things, and realizes the coordination and unification of economic, environmental and social benefits.

Description

Technical field: [0001] The invention relates to the field of lubricating oil additives using Ni-P alloy nano powder recovered from electroless plating waste liquid, in particular to the formulation, preparation and use of a lubricating additive containing Ni-P alloy nano powder recovered from electroless plating waste liquid and used in different friction occasions. method of use in the case. Background technique: [0002] Electroless nickel plating is widely used in the electronic components of petroleum, chemical, machinery manufacturing, aerospace and other industries due to its advantages of uniform coating, no need for external power supply, high hardness, good wear resistance, and plating not limited by the size and shape of parts. surface treatment. However, after the electroless nickel plating solution is used for a period of time, due to the accumulation of by-products such as phosphite, the performance of the plating solution decreases, the solution ages, and was...
