Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a method for simulating the aging of knitting machine lubricating oil in view of the fact that the existing lubricating oil aging method cannot accurately simulate the aging process of knitting machine lubricating oil. Infrared characterization means to prove that the composition of the two is the same, and a variety of aging oil stains with different cleaning degrees can be prepared, so as to be used for cleaning research or lubricating oil development of knitted semi-finished oil stains

Abstract

The invention provides an ageing simulation method of knitting lubricating oil, and belongs to the technical field of ageing simulation methods of lubricating oil. The ageing simulation method of the knitting lubricating oil is characterized in that a drum ball mill serves as a testing instrument, an infrared lamp irradiates to accelerate ageing of the lubricating oil, and an oil stain sample comprises the following materials in parts by weight: 10-50 parts of metal filing, 1-15 parts of fiber flocks and 80-100 parts of knitting lubricating oil; mixed gas of one or more of nitrogen, oxygen, carbon dioxide and air serves as a gas medium; and an ageing simulation test is carried out under the conditions that the temperature of the surface of a ball-milling drum is 30-90 DEG C, the time is 30-80 hours, and the revolving speed of the drum ball mill is 200-800 r / min. By the ageing simulation method of the knitting lubricating oil, aged oil stain which is quite close to oil stain generated in a production process can be prepared, an infrared radiation characterization means proves that ingredients of the aged oil stain prepared by the ageing simulation method and the oil stain generated in the production process are the same, and various kinds of aged oil stains with different cleaning degrees can be prepared, and then can be used for cleaning research of oil stains of knitting semi-finished products and development of lubricating oil.
