The linear guide rail is used under water. Besides stainless steel, what else can be used to prevent rust?
When using a linear guide rail, a good lubrication function must be provided. If it is used without lubrication, the rolling part will wear faster and its service life will be shortenedLubricants have the following benefits:(1) reduce the friction between the moving parts, thus preventing coking and reducing wear(2) the oil film is formed on the rolling surface to reduce the stress acting on the surface and prolong the rolling fatigue life(3) the film covered on the metal surface to prevent rust. In order to give full play to the function of linear guide, please provide lubrication in accordance with the specific conditions of use. Even with the straight rail seal baffle, internal lubricant will seep out gradually in practice. Therefore, the system needs to use the conditions of lubrication at appropriate time the linear guide interval. Mainly used grease or oil as lubricant. The sliding surfaceThe requirements required for lubricants generally include the following:(1) high oil film strength (2) low friction and high abrasion resistance (3) (4) (5) with high thermal stability and corrosion resistance. (6) high rust resistance (7) dust and moisture content less. (8) even after repeated mixing, oil viscosity did not change significantly.
Derusting method:It is an important job to prevent the rusting of the linear guide rail. After pickling, cleaning and grinding, multiple procedures are indispensable.From the source to reduce the probability of rust, after the arrival of raw materials is first stored in the open environment, let the occurrence of rust, a few days later we were on a surface grinder processing grinding, grinding after placed in brine generally stored for about 3 months, thus greatly solves the problem of rusting.The straight rail immersed in an aqueous solution of 5% sodium nitrite and 0.6% sodium carbonate is still a good rust inhibitor option.Regularly antirust oil, regular maintenance, to guide selection of rusty industrial cleaning cloth on the linear guide rail corrosion position rub-a-dub-dub, remove the rust until now, and then use a clean cloth clean up, and then do the anti rust treatment.The corrosion of linear guide rail is mainly caused by two reasons:One is the metal corrosion of the bearing itself;Two is the erosion of tool elements.CSK linear guide itself accounts for a large proportion of metal erosion, because of the special causes of the work environment, rust can not be avoided many times. Especially when the weather is hot, the operator's hand sweat can also cause corrosion of CSK linear guide, this is because the sweat on the surface membrane of human sweat will contact bearings, the metal surface will sweat salt with metal reflecting erosion incurred. Of course, if there is effective protection measures, this situation can be avoided, such as with professional take parts of professional gloves to install operations.
Simple is to grease, but it will rub off.Then you can wire other metal on the surface of your rail, but the cost is high.These two methods of choosing matters that are more relevant to your situation.Ohmic anode protection method two upstairs man said, I think your guide under the water.
