Overview: Zro-45 polishing lubricant oil is surface treatment material composed by a special vegetable oil , machine oil and anti-rust agent, anti-friction agent and nano-materials. It can improve the anti-rust performance and smoothness of welding. Due to the presence of nano-materials , it also has excellent performance for copper coated wire. Performance: Form: pale yellow oily liquid specific gravity: 0.91 (20 ?) Viscosity: 40cst (40 ?) ph value: 6.7 moisture: 0.3 max Application: It can be used for all drawing passes and will form thin film under in a bad cooling conditionn, it may appear coke, drawing speed of crude rough is 100 ~ 200m / min, while the small size of the drawing speeds is up to720 ~ 800m / min, the film is easy to clean. 1. Properties Pale yellow oily liquid Specific gravity 0.91 (20 ?) Viscosity 40cst (40 ?) Ph value of 6.7 or less moisture 0.3 Ingredients: vegetable oil, additives 2. Features It has excellent lubricity and significant anti-rust performance to the copper wire. The anti-friction agent and nano-materials make wire surface more smooth, and more smoothly for wire feeding.The materials do not contain any hazardous and noxious substances, when welding the lubricant on wire surface does not produce harmful substances. 3.Uses Polished copper or copper wire for surface coating 4.Usage Directly pour into the mould box Used in circular fashion Coating by felt jig 5. Notes: Black residue when direct drawing, may be caused by water incorporation or polishing mold too hot, remove the deposition , use the upper layer oil.
