Applications of PAG （polyglycols）base oil in high temperature chain oil
Leave a message
PAG polyether as a base oil includes polymer polyether, PAG water-soluble polyether, and PAG water-insoluble polyether.
PAG polyether is a random polymer composed of EO and PO starting from different amines or alcohols. Polyether is a colorless liquid with a wide distribution of viscosity, ranging from 20-75000. Polyether belongs to polymers. The chain length/molecular weight distribution is the most critical indicator of product performance.
Polyether's physical properties will also be affected by the ratio of ethylene oxide (EO) and propylene oxide (PO).
Water solubility and pour point depend on the EO/PO ratio.
Applications of the Polypropylene glycol.
Fire-resistant Hydraulic Fluid
Polymer polyether is widely used as base oil and thickener of water-glycol fire-resistant hydraulic fluid (HFC water glycol fluids).
Quenching medium
The cooling rate of the quenching liquid can be controlled by controlling the concentration and molecular weight of the PAG polymer in the quenching liquid.
High-temperature Chain Oil
Some types of polyether are used as base oil for high-temperature chain oil, widely used in high-temperature ovens, textiles, printing and dyeing, and heat setting machines, food-grade equipment chain transmission system lubrication, also suitable for automotive paint line chains, building materials industry Chain transmission system of equipment such as high-temperature drying room, etc.
These types of polyether products have the following characteristics:
- Excellent high and low-temperature performance, the machine is easy to start at low-temperature, and can be used for a long time under the condition of not exceeding 220 C;
- High flash point, low volatility, low carbon deposition, and low coking tendency for long-term use at high temperatures, so the chain and equipment can keep clean for a long time;
- Excellent lubricating performance, excellent lubricity under high temperature and heavy-load conditions;
- Very good detergency, the PAG base oil can clean the chain polluted caused by previous bad lubricant liquid;
- Non-toxic, odorless, and harmless to human bodies and the environment.
high-temperature chain oil (PAG base oil) that meets most high-temperature places, such as stenter machines in the textile printing and dyeing industry, transmission chains in paint workshops, in various ovens.
