Foamless low temperature degreasing agent

Abstract

The invention provides a non-foaming low-temperature degreasant which belongs to the chemical technique field. The non-foaming low-temperature degreasant is prepared from components by weight percentage as follows: water 77.4-96.35%, sodium hydroxide 3-20%, polyoxyethylene nonyl phenyl ether 0.1-0.5%, fatty alcohd-polyoxyethlene ether 0.1-0.5%, carmowax 0.05-0.1%, disodium EDTA 0.2-0.5%, siliconeantifoam agent 0.1-0.5%, fatty alcohol polyethenoxy ether type osmotic agent 0.1-0.5%. The non-foaming low-temperature degreasant has advantages of better oil removing effect, low use temperature, and simple preparing method. The non-foaming low-temperature degreasant has better application prospect.

Description

A non-foaming low-temperature degreasing agent technical field The invention belongs to the technical field of chemical industry, in particular to a foam-free low-temperature degreasing agent. Background technique In the steel rolling process, in order to wash off the oil on the surface of the steel plate, degreasing agents are widely used to enhance the degreasing effect. At present, the degreasing agent used in China can only achieve good results when used at a higher temperature (75-85 ° C), and a large number of air bubbles are generated during operation, which has the following defects: (1) the use temperature is higher, then The heat required for heating is large, the energy consumption is large, the fuel required for heating is wasted, and the air environment is polluted; (2) Bubbles generated during use will take away part of the degreasing agent, resulting in waste of degreasing agent; (3) The use process A large number of air bubbles generated in the process mak...

At present, the degreasing agent used in China can only achieve good results when used at a higher temperature (75-85 ° C), and a large number of air bubbles are generated during operation, which has the following defects: (1) the use temperature is higher, then The heat required for heating is large, the energy consumption is large, the fuel required for heating is wasted, and the air environment is polluted; (2) Bubbles generated during use will take away part of the degreasing agent, resulting in waste of degreasing agent; (3) The use process A large number of air bubbles are generated in the air, which makes the working environment on site worse

Most of the degreasing agents widely used in iron and steel enterprises are high-temperature type (75-85°C), and more than 90% are imported from abroad, which are expensive; there is an urgent need to develop a low-temperature degreasing agent to meet the requirements of industrial production
