Product Description

Introduction

1. Modified ethylene glycol coolant, also known as inhibitory ethylene glycol solution, using polyester grade ethylene glycol (99.9%), softening water, special corrosion resistance package, special fluorescent leak detection agent production and processing. It has non-corrosive, low viscosity, high thermal conductivity, low toxicity, non-volatile,
High flash point, wide temperature range and long life. Suitable for a variety of materials: carbon steel, stainless steel, copper, brass, cast iron, cast aluminum,
Flux, etc. It can be used alone or mixed with water, ethylene glycol, ethanol, etc., according to the different process needs of customers on site. Widely used
In the process cooling circuit and air conditioning system, it is used to provide anti-freezing and anti-corrosion protection.
2. The density of modified glycol secondary refrigerant is 1.103g/cm³, the viscosity is 12.46cP, the thermal conductivity is 0.27W/m/K, and the specific heat is
3.48kJ/kg/K, the lowest anti-freezing temperature -70ºC, the lowest available flow temperature -50ºC, the highest available temperature 135ºC. Modified glycol carrier refrigerant
Contains highly effective compound corrosion inhibitors to protect metals in both high and low temperature applications.
3, anti-corrosion package mainly includes: iron corrosion inhibitor, copper corrosion inhibitor, antioxidant, anti-acidifying agent, PH stabilizer, scale inhibitor, sterilization
Algal agent, anti-aging agent, oxidation type corrosion inhibitor, passivation film type corrosion inhibitor, synergist and so on. For carbon steel, stainless steel, copper, yellow
Copper, cast aluminum, cast iron, solder and other metals are non-corrosive, and have no effect on rubber, plastic, polyester and other organic matter
