Product constitute, performance, usage and matters need attention:
989 anti-wear water-ethylene glycol anti-burning hydraulic fluid has the characteristics like: good non-flame property, high viscosity index, excellent lubricity and rust protection. It has good fire safety in high temperature and high pressure environment. This product has low freezing point, which can reach -50℃. It is mainly used in extruding machine, die-casting machine, rolling mill, machinofacture, electron and other industries. Carrying capacity can reach 21MPA or above.
Water-ethylene glycol anti-burning hydraulic fluid has various series products
About abrasion resistance: A. four-ball instrument; B. Special wear testing machine.
Degree of pollution is about 5-6 grade. Outgoing product is 8 grade.
Avoid water, dormant oils and other impurities in storage.
The choose of related materials
1.Applicable materials are:
NBR, Butyl ester rubber, polyvinyl chloride plastics, nylon plastics, copper silicon plastics, styrene plastics, methacrylonitrile plastics, aluminium alloy, iron, epoxy resin, silicon rubber, etc.
2. Non-applicable materials are:
Ordinary industrial paint, zinc, cadmium, MPUR, natural rubber, leather, etc.
Since water-ethylene glycol contains vapor and liquid phase anti-rust agent, it has good rust resistance, the tank wall can't be painting.
Matters need attention
1.Users can customize the degree of pollution according to the equipment. Our company can always meet the requirements of customers.
2.Using temperature control range: Open tank is within 60℃; Closed tank within 70℃, 50℃ is the best.
3.Water-ethylene glycol has excellent cold starting performance. Medium without heating.
