There is rotational, have HRB bearing ( ) Jiaxing bearing group co. , LTD. To tell you about the main factors influencing the anti-rust oil degreasing operation process of jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability. Degreasing quality mainly depends on the degreasing temperature, skim time, mechanical action and degreasing agent four factors. 1. Skim temperature in general, the higher the temperature, skim the more thoroughly. This is because the three reasons, first, make the change and the physical properties of the oil temperature, such as high drop point antirust grease, vaseline, solid paraffin, etc. , at low temperature even with a high concentration of alkali liquor is also difficult to clean. But when raise the temperature of the oil, their viscosity is reduced, and even form droplets, conducive to eliminate. Second, to promote chemical reaction, the general said, every 10 degrees temperature, chemical reaction rate doubled. Third, accelerate the movement of the surfactant molecules, thus promotes infiltration, emulsification, dispersion, and so on. With the increase of temperature, the solution's ability to dissolve dirt is also improved. However, not all situations are the higher the temperature, the better, all kinds of degreasing agent has its suitable temperature range and certain kinds of surfactants used in the degreasing fluid, high temperature can make the surface active agent precipitation gathered as oil bead adhesion on the surface, causing uneven phosphating film hair flower. 2. Degreasing time in the operation of degreasing, must make the pledge that we shall have enough degreasing time, pressure spray degreasing time usually is 1. 5 ~ 3 minutes, dipping skim for 3 ~ 5 minutes ( Depending on the types of oil and how many) 。 Increase the degreasing time, namely prolonged contact of degreasing fluid and the oil, so as to improve the effect of degreasing. The longer the more oil, degreasing time we have to. In assembly line work, often are not allowed to use too long, so generally with jet to skim first 1 minute, defatted with dipping 3 minutes. 3. Mechanical action in degreasing, with the aid of pressure injection or stir the mechanical action is very effective, because, when the jet force fresh degreasing solution contact with parts surface is good, and the uniform degreasing fluid content, is helpful to improve the effect of degreasing; Injection on mechanical forces prompted degreasing agent penetration and damage of oil film, thus effectively forced the oil from the parts surface; Jet prompted from parts of oil emulsification and dispersion in degreasing solution in oil pollution prevention and adsorption to wash the parts on the surface. In the low temperature degreasing, mechanical action is particularly important. General said, pressure injection than dipping skim speed more than 1 times. Injection pressure is usually ( 0. 1 to 0. 2) Mpa( Used for pressure spray degreasing agent must be low foam, in order to avoid the bubble too much affect the normal operation and degreasing fluid loss) , dipping skim cannot be considered static impregnation, must be equipped with circulation pumps, make the solution agitation, for about an hour circulation trough liquid product 5 times. 4. The influence on the effect of degreasing agent to skim degreasing agent composition and use method of the degreasing effect has a great influence. For example, alkali liquor containing surfactant degreasing solution than single alkaline degreasing effect is good. For the high dropping point of solid or semisolid fat, clean with solvent than using other effective degreasing effect. In order to improve the oil emulsifying and dispersing ability, raise the degreaser are effective, content of surfactant in different kinds of surfactants and the effect of different alkaline substances are defat produce certain differences, good degreasing agent is through a large number of trials, the component proportion each other were repeated screening and confirming. For alkaline degreaser containing surfactant, is the most effective play a role of wash in the critical micelle concentration of surfactant to upper limit. In use process, degreasing agent will constantly consumed, lower the concentration, therefore, must be regularly adding degreasing agent, to maintain the necessary concentration. Degreasing effect of degreasing agent and the relationship between the concentration is not a straight line up, so in the case of degreasing quality requirement is very high, should not take great increase in the concentration of method, and secondary degreasing method should be used, two degreasing fluid can be the same, and there is no need to additional improve concentration. In actual use, must consider the factors, makes the control of every factor in the best state and defatted achieve satisfactory results. 24-hour customer service hotline: if you are more interested in jiaxing bearing group company introduces industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - - - - - - Editor: jiaxing bearing sourcing consultant LTD.
