How to judge the quality of aluminium wiredrawing oil / aluminium alloy drawing oil?Industry experts hope to help answer
As the aluminum wire drawing, Aluminum Alloy drawing process in an important auxiliary aluminum wire drawing oil quality, directly affects the quality of the finished products and finished aluminum wire drawing line safety. Many small and medium enterprises, cheap purchase non-standard manufacturers of aluminum wire drawing oil, on the surface looks cheap, the actual use of more expensive! And good aluminum wire drawing oil / Aluminum Alloy pulled out of the wire drawing oil light, good oxidation resistance, not easy to fire, but also conducive to environmental protection factory. As an ordinary cable factory production, technology and procurement staff, how to judge the quality of essential oil / Aluminum Alloy brushed aluminum wire drawing oil. Below I simple to explain
Base oil is the raw material of aluminum wire drawing oil important. His quality of drawing oil quality is crucial, she decided the high temperature performance, drawing oil shear performance, viscosity temperature characteristics, antioxidant capacity, performance and evaporation loss will cause sludge and carbon smoke, harmful ingredients idle base oil production according to standard. Can be divided into standard oil and non standard oil. Standard oil (base oil production in accordance with the relevant standards) generally refers to the previous Sinopec Corporation issued neutral paraffine standard, intermediate and naphthenic base oil standards (SN, ZN, DN). The so-called "non standard" refers to the 3 basis Oil Corporation and Sinopec issued relatively, generally lower than the standard oil company. Non standard base oil containing sludge, originally yellow metal impurities, to some extent, this will lead to the poor performance of aluminum wire drawing oil, anti settling The oxidation is poor. So we often see that the non-standard aluminum wire drawing oil production oil color is brown, brown, black and brown. The standard base oil production drawing oil is golden yellow, yellow, pale yellow (such as AMTT S580A al Mary oil) or light transparent (such as an S590 aluminum small oil) oil. The color is very beautiful, peanut oil, cooking oil. We like
Flash point (Flash Point), also known as quenching, refers to under specified conditions, minimum temperature flash fire when the mixture and flame contact heating oil escaping steam and air, with C said. Aluminum wire drawing oil consists of oil and water two, oily flash point should be greater than 180 degrees, the water is not water before the flash point is greater than 100 degrees, the water after burning. Low flash point drawing oil is easy to fire, smoke, cause a safety hazard. AMTT aluminum wire drawing oil and Aluminum Alloy drawing oil flash point for high flash point drawing oil (220 degrees -230 degrees Celsius), deflagration phenomenon does not appear in the high temperature drawing process, eliminate safety hazards, non low quality, low price drawing oil can be compared.
