Water-hardening heat treatment agent (quenching solution) 
 * Product Description 

 Hai Yi PAG polymer hardening agent is a water-soluble quenching agent, selection of quality raw materials abroad, refined, has a unique inverse solubility (generally known as cloud point effect), to overcome the water-cooled fast, easy to make the workpiece cracking; oil slow the cooling, quenching effect of poor and flammable and other shortcomings. Safety, environmental protection, long life, low cost, and now more and more international oil prices, more stringent state environmental climate, has become first choice for quenching medium heat treatment industry. 
 Second, quenching agent Hai Yi PAG has the following advantages: 
 A safety and environmental protection, sea completely beneficial burning PAG hardening agent, no fire risk, non-toxic, no fumes, so that greatly improved the working environment to meet the environmental protection department of the company's environmental requirements. 
 2 by controlling the concentration of quenching liquid, can be close to the oil in the water between the cooling rate, to meet different requirements of material and quenching the workpiece. 
 3, significantly lower operating costs, usually the cost of quenching liquid parts of the PAG quenching oil price equal to only about 20%. 
 4 benefits the sea PAG hardening agent and water heat capacity heat capacity was similar (quenching oil heat faster than a lot), can increase the plant's production capacity, thereby enabling companies to increase efficiency than before. 
 5 hardened layer deep, quenching hardness even without soft spots, significantly reduce the tendency of quenching distortion and cracking of low, medium and large hardened steel particularly suitable for induction. 
 6 on the workpiece free from corrosion, rust, and the role of short-term and long service life, not aging deterioration, time to clean the workpiece after quenching tempering directly. 
 7, the concentration of quenching agent easy to control the test easy to test, maintain and preserve special simple. 
 8 hardening agent in use, with the less, the use of low cost, comprehensive economic good.
