⁣Methods for treating chemical wastewater
1. Physical processing methods
Physical treatment methods are a common approach in chemical wastewater treatment, mainly used to remove insoluble substances such as suspended solids and oils from wastewater. The specific methods include filtration, gravity precipitation, air flotation, and adsorption. The air flotation method removes oil and suspended solids by introducing a large number of tiny bubbles into the wastewater, causing suspended particles to adhere to the bubbles and float to the water surface. ‌

2. Chemical treatment methods
Chemical treatment methods remove pollutants from wastewater through chemical reactions and are suitable for treating high concentration, difficult to degrade organic and inorganic substances. Common methods include chemical oxidation, coagulation, and electrolysis. Chemical oxidation method uses oxidants such as ozone, hydrogen peroxide, etc. to oxidize organic matter into harmless substances. The coagulation method involves adding coagulants to coagulate suspended solids into large particles and remove them. The electrolysis method removes pollutants through electrochemical reactions. ‌

3. Biological treatment methods
The biological treatment method utilizes the metabolic activity of microorganisms to degrade organic matter and is suitable for treating organic wastewater. Common biological treatment methods include aerobic and anaerobic treatment technologies. Anaerobic biological treatment converts organic matter into methane and carbon dioxide through anaerobic bacteria under anaerobic conditions, and is suitable for high concentration organic wastewater. Aerobic biological treatment involves the degradation of organic matter by aerobic microorganisms. ‌

⁣Cinnamyl ether has defoaming properties. Polyether defoamer is a major variety of defoamer at present. It has the advantages of non-toxic, tasteless, non-irritating, resistant to hard water, acid and alkali, and good compatibility with the system. Compared with another class of silicon-containing defoamer, although its defoamer performance is not high, its anti-foam performance is quite excellent.

⁣Science popularization of hazardous chemicals knowledge
Dangerous chemicals refer to chemical substances that have physical and chemical hazards (such as flammability, explosiveness, oxidation, etc.), biological hazards (such as toxicity, corrosiveness, etc.), and environmental hazards.

The hazards of hazardous chemicals to human health and preventive measures
Dangerous chemicals pose various hazards to the human body, including eye irritation, skin burns, respiratory tract damage, nerve paralysis, etc. Preventive measures include:

1‌. Understand the characteristics of the hazardous chemicals used, do not operate blindly, and do not use them in violation of regulations.
2. Properly store hazardous chemicals, with complete labels, sealed storage, away from heat, light, and fire.
Do not store hazardous chemicals in the living room.
4. Do not carry hazardous chemicals when taking boats or buses.
5. Strictly prevent the accumulation of high concentration flammable and explosive gases indoors

⁣Adipic acid, also known as fatty acid, is a carboxylic acid organic compound that can be used as a chemical reagent, as well as in plastics and organic synthesis.


It is a white crystalline powder, slightly soluble in water, and acidic when dissolved in water.


Adipic acid, as a fundamental component of various chemical products, is currently the most important aliphatic dicarboxylic acid in industrial production


Approximately 3 million tons of adipic acid are used annually worldwide to synthesize monomers for nylon-66. Additionally, adipic acid is also used to synthesize polyesters, polyurethanes, lubricants, plasticizers, adiponitriles, and as a flavoring agent in food

⁣In a corner of the production workshop, we discovered this small beauty. Amidst the noisy mechanical noise, the workers were focused on operating every detail. It is these unremitting efforts that have enabled our products to lead in quality and innovation.

⁣Let's take a look at the room composition of Zhishang Chemical Laboratory.

⁣Triethyl phosphate is an organic reagent that is stable at room temperature, has good solubility in various resins, low viscosity, and low color, so it can be used as a special solvent; Epoxy resin additives (reducing viscosity); Anti coloring agents during polyester fiber processing (to improve dyeing quality); Textile oil additives;

Used as a gasoline additive, it can prevent detonation, improve octane rating, and enhance the stability of leaded gasoline during storage; It can also be used as a control agent for gasoline surface ignition and as a decomposition inhibitor for tetraethyl lead at high temperatures; Non corrosive gasoline additive; Catalyst for polyester fiber polymerization; Modifiers for graphite products; Plasticizers; Extraction agent; Raw materials for pesticides and insecticides.

Triethyl phosphate hydrolyzes when it comes into contact with water, so it should be kept moisture-proof during storage. Due to its hydrolysis, PO43- is released, making it a homogeneous precipitant that forms insoluble phosphate precipitates. It is often used as a precipitation reagent for zirconium and hafnium and as a diffusion source for measuring semiconductors.

In addition, trimethyl phosphate is also a phospholipid extractant used for extracting and separating certain metal ions.

⁣Diisooctyl sebacate is an excellent low-temperature resistant plasticizer commonly used in the plasticizing application technology fields of polyvinyl chloride cable materials, cold resistant films, artificial leather, and other resins.
Meanwhile, diisooctyl sebacate also has an important use as a base oil for biomass based lubricants. Due to its high temperature resistance, low temperature resistance, and biodegradability, this base oil
Can be used as a base oil for jet engine lubricants.

⁣Six key points for laboratory sample preservation to avoid pitfalls!
🔍 The preservation of laboratory samples is crucial, and the following seven points can help you avoid common pitfalls:
1. Consistency: Ensure the consistency of sampling between the experimental group and the control group, such as the size and location of tissue samples, gender and age matching of blood samples, and sampling time of urine samples.
2. Impurities removal: Remove impurities unrelated to the experiment, such as blood from animal tissues, soil pollutants from plant tissues, and culture media for bacterial cells and cells. Recommend using PBS buffer or physiological saline, and absorbent paper to absorb residual liquid.
3. Low temperature storage: Sample pretreatment should be carried out at low temperatures as much as possible, and impurity removal and packaging operations can be performed on ice. It is usually stored in a -80 ℃ refrigerator.
4. Packaging: Packaging should be carried out according to the experimental dosage, avoiding repeated freezing and thawing to ensure the integrity of the sample.
5. Rapid processing: The collection, preparation, storage, and transportation of samples should be as rapid as possible to reduce the time from sample collection to formal experiments.
6. Clear marking: Use a high-quality marker to clearly mark the sample name, avoiding confusion of the samples
