With the rapid development of the economy, the country is paying more and more attention to environmental protection issues. At the same time, people have higher and higher requirements for industrial cleaning efficiency. Ultrasonic cleaning equipment is also used more and more widely. Many companies have purchased ultrasonic cleaning machines. After cleaning, the issue of sewage discharge will be considered.

    At present, some industrial parks have sewage treatment systems that can be discharged directly. If not, companies generally collect it and give it to outside environmental protection companies for treatment, which also increases the company's production costs. Therefore, many companies are now gradually using hydrocarbon cleaning agents instead of the previously used water-based cleaning agents.

1. What is a hydrocarbon cleaning agent?

Hydrocarbon cleaning agent is a new type of environmentally friendly industrial solvent cleaning agent. It is composed of two elements: carbon and hydrogen. Its main component is hydrocarbons. It is obtained by deep processing of crude oil and is formulated with active solvents, solubilizers, stabilizers, etc., so it is called a hydrocarbon cleaning agent. Hydrocarbon cleaning agents are widely used industrial cleaning agents in Europe, the United States and Japan. They are used to replace trichlorethylene, methylene chloride, n-bromopropyl bromide, diesel, kerosene, gasoline, white electricity oil, Tianna water, and stain removal water on a large scale. Wait for non-environmentally friendly cleaning agents.

2. Development history of hydrocarbon cleaning agents

In the 1950s, traditional hydrocarbon cleaning agents, mainly gasoline, kerosene, and diesel, were widely used in the cleaning industry. The disadvantage is that these traditional solvents are highly toxic, causing great health risks to workers and damaging the environment.

   In the 1990s, hydrocarbon cleaning agents were maturely used in industrial cleaning in Europe, Japan and other countries. Our country introduced it into the country in 2002. After development by industry insiders, hydrocarbons completed the task of replacing chlorinated solvents in 2005 and entered a stage of rapid development.

Chlorinated solvents (trichloroethane, trichloroethylene, methylene chloride, etc.) that were once widely used are gradually restricted by local governments due to their toxicity and strict environmental control. Moreover, the ISO14000 series has restrictive requirements for chlorine-containing cleaning agents. , in order to obtain ISO14000 certificates, companies gradually began to use hydrocarbon-based cleaning agents and water-based cleaning agents. However, water-based cleaning agents are not easy to dry, and the cleaned products often show rust and spots. There are also issues such as drainage and lack of water resources in China that need to be considered. Various manufacturers have gradually begun to research alternatives.

   In the next ten years, hydrocarbon cleaning agents developed steadily and continued to expand in the application industry of water-based cleaning. Finally, in 2015, they replaced water-based cleaning agents and entered the track of rapid development again!

2. Advantages of hydrocarbon cleaning agents

Since the advent of hydrocarbon cleaning agents, they have been widely used in various industries such as motors, electronic devices, automobiles, precision parts, and heat treatment in many countries. Hydrocarbon cleaning agents are one of the best choices in the world in recent years to solve the problem of the damage of fluorine-based solvents to the ozone layer and the toxicity of chlorinated solvents. They are commonly used cleaning solvents in the United States, Japan, and France with strict environmental regulations. They are also the ones that China is now working with. Future Trends. Its ozone depletion coefficient (ODP) is zero and has no pollution to the atmosphere.

1. It neither destroys the ozone layer nor discharges sewage. The ozone destruction coefficient (ODP) of the hydrocarbon cleaning agent is zero, which solves the problem of the destruction of the ozone layer by fluorochlorine solvents and the toxicity of chlorinated solvents to human health and environmental pollution.

2. Good cleaning performance. The SP value of hydrocarbon cleaning agents is close to that of most lubricating oils, anti-rust oils, and machining oils. According to the similar miscibility principle, hydrocarbon cleaning agents are easily dissolved and can wash away all kinds of dust and metal shavings on the workpiece.

3. Low toxicity. Hydrocarbon series cleaning agents use linear and iso-alkanes as main components to remove toxic aromatic hydrocarbons and sulfur-containing compounds. After testing by the chemical toxicity identification department, the inhalation toxicity, oral toxicity and skin contact toxicity of the hydrocarbon series cleaning agents are basically non-toxic and are not carcinogens, so they can be used with confidence.

4. Can be completely evaporated without leaving any residue. Hydrocarbon cleaning agent is a very pure refined solvent that can be completely volatilized at room temperature and heated conditions. It can be completely volatilized after cleaning, leaving no residue on the surface of the workpiece.

5. No corrosion to metal. Hydrocarbon series cleaning agents are neutral cleaning agents. They will not cause acidification when recycled and reused, and will not corrode metals.

6. High recycling rate. Hydrocarbon cleaning agents have a high recycling rate and can reduce sewage discharge.

7. High insulation and wide range of uses. It does not contain water and has high electrical insulation properties, and will not cause expansion or deformation of most coating films and plastics.

4. Types of environmentally friendly hydrocarbon cleaning agents

1. Dehydration hydrocarbon cleaning agent: It can clean and remove water, cutting fluid, water-based cleaning agents, etc. from the workpiece.

2. Anti-rust hydrocarbon cleaning agent: cleaning and anti-rust, suitable for cleaning iron parts, carbon steel and other metals that are prone to rust. The anti-rust period can reach 15-90 days.

3. Flux-removing hydrocarbon cleaning agent: Clean flux, oil, dust, etc. on electronic instruments, PCB circuit boards and other parts.

4. Carbon ash removal type hydrocarbon cleaning agent: cleans carbon black, powder, oil stains, etc. on cylindrical stamping and drawing workpieces such as batteries and capacitors.

5. Wax-removing hydrocarbon cleaning agent: used to clean polishing wax on workpieces such as hardware bathrooms, watch electroplating, jewelry processing, lighting manufacturing, etc.

6. Remove resin-type hydrocarbon cleaning agents: clean oil stains, natural resins and synthetic resins on parts and equipment.

5. Precautions for using environmentally friendly hydrocarbon cleaning agents

1. Hydrocarbon cleaning agent is a solvent that is insoluble in water. Do not mix it with water. It will cause turbidity and cannot be used.

2. Hydrocarbon cleaning agents cannot clean water-soluble oil stains such as cutting fluids. If hydrocarbon cleaning agents must be used for cleaning, first use dehydrating agents for dehydration, and then use hydrocarbon cleaning agents for degreasing and cleaning.

3. Hydrocarbon cleaning agents have a higher flash point and slower evaporation rate, making them suitable for equipment cleaning.
