  1. Overview of Market Development

          ODSIt's an ozone-depleting substance(ozone depleting substance)Abbreviations,ODSin the cleaning industryMainly refersCFC-113,TCA,CTCThree cleaning agents. Although these substances have good cleaning effect and economic benefits, they can destroy the ozone layer, cause the ozone layer hole, and seriously endanger the safety of the earth.

         ODSThe prohibition of cleaning agents has prompted countries around the world to develop a variety of alternatives. In Europe and the United States and other developedNational, commonly used water-insoluble flammable organic solvents including hydrocarbon solvents and silicone solvents(polydimethylsiloxane). The semi-aqueous cleaning agent prepared by these two types of flammable solvents is the most important variety of semi-aqueous cleaning agents currently used.

Nonflammable organic solvents, such as halogenated hydrocarbons containing fluorine, chlorine, bromine and other elements ODS Alternative solvents are also availableIn semi-aqueous form, because they are insoluble in water. To increase compatibility with water when configuring, also addSurfactants or alcohols, ethers, ketones and other water-soluble organic solvents, these substances often also have a reducedEffect of surface activity on low surface tension. At present, the type and quantity of this type of water-based cleaning agent is very small.

In addition, the cleaning agent products on the market include brominated hydrocarbon solvents, organic fluorides(HCFC,HFO,HFE,PFC)and natural organic matter(plant line)Wait.

 

  1. current situation of market demand

Cleaning agents used in the field of industrial cleaning,ODS(ozone-depleting substances) cleaning agents account for a large proportion, especially in precision cleaning, trifluorotrichloroethane (CFC-113) and 1.1.1-Trichloroethane is called"The best cleaning agent" is very popular. With people's concern and attention to environmental protection and human health, looking for new alternatives to eliminateODSCleaning agents have become a priority. To this end, government departments around the world,Scientific and technical personnel and related enterprises have made great investment, and various alternative products and alternative technologies have emerged. From the sutracomprehensive parity in terms of economy, application, safety and environmental protection,hydrocarbon cleaning agentis extremely promising ODSSubstitutes.

  1. Market development trend

The use of existing cleaning technology to change the cleaning process: water washing and semi-water washing as the representative, halogenated hydrocarbon cleaning agent panning.The inevitable trend of elimination.

A halogenated hydrocarbon is a hydrocarbon molecule in which some or all of the hydrogen atoms are replaced by halogen atoms.Fluorine, chlorine, bromine, iodineTakeGenerated compounds. The most commonly used halogenated hydrocarbon cleaning agents in the field of industrial cleaning are chlorinated hydrocarbons and HCFCsTwo categories, including dichloromethane, chloroform(Chloroform,1,1,1-Trichloroethane, trichloroethylene, tetrachloroethylene,Carbon tetrachloride, trifluorotrichloroethaneF-113Halogenated hydrocarbon cleaning agent because of its cleaning ability, not burning,The advantages of fast drying and easy distillation regeneration are widely used, according to statistics. 2000 In China, more than one million tons of halogenated hydrocarbon cleaning agents were used for industrial cleaning.But the halogenated hydrocarbon cleaning agent in use to people, cleaning and the environment will bring many hazards:

 

1Toxicity: the above solvents F-113and 1,1,1-Trichloroethane is very toxic outside, through the skin,Breathing contact or accidental ingestion will cause liver, kidney, blood poisoning, light dizziness, vomiting, severe cases will cause shockto death. Some solvents also produce extremely toxic phosgene under sunlight, which has a carcinogenic effect. Therefore, the rightThere are strict requirements for the use of places and personnel protection, and the maximum allowable concentration in the air is 10-500ppm.

2Corrosion: Because most of the halogenated hydrocarbon cleaning agent contains chlorine atoms, it will decompose under certain conditions.Hydrochloric acid, corrosion of equipment and metal workpieces. Most chlorinated hydrocarbon solvents will dissolve and dissolve plastic rubber parts.Expansion, deformation or embrittlement, so that its cleaning range is limited.

3Large evaporation loss: low boiling point of chlorinated hydrocarbon cleaning agentgenerally in 40~80, are volatile liquids, in the process of transportation, storage and use of about. 40%The cleaning agent is lost due to evaporation.

4Pollution of the environment: chlorinated hydrocarbon solvents are not natural degradation, after the discharge of air, water and soil have more serious pollution.

5Destruction of the ozone layer: F-113carbon tetrachloride and 1,1,1-Trichloroethane volatile gases trapped in the atmosphereIn, with the rise of air flow, chlorine atoms are decomposed by ultraviolet radiation in the stratosphere. As a catalyst, chlorine atoms can cause long-term damage to the ozone layer, reduce the role of the ozone layer in blocking ultraviolet rays, and bring harm to people and plants on the earth.

The toxic carbon tetrachloride, chloroform, trichloroethylene and tetrachloroethylene in halogenated hydrocarbon cleaning agents have long beenPeople attach great importance to the beginning of the use of gas masks, cleaning room closure and cleaning equipment closure and other methods to reduce its spread, limit the scope of pollution. It was later discovered F-113After the superior performance, few people make it.Cleaning with such solvents.
