What is a non-ionic surfactant
Non ionic surfactants are a type of surfactant that do not produce ions in aqueous solutions. This means that they will not decompose into positively or negatively charged ions in aqueous solutions. Unlike ionic surfactants (such as cationic or anionic), the molecular structure of non-ionic surfactants does not contain dissociatable ionic groups.
The general structure of non-ionic surfactants includes a hydrophilic (polar) head and one or more hydrophobic (non-polar) tails. The hydrophilic head is usually an ether bond structure containing multiple oxygen atoms, such as a polyoxyethylene (EO) chain. Hydrophobic tails are usually long chain hydrocarbons.
Some of the main characteristics of non-ionic surfactants include:
Mildness: They are usually less irritating to the skin and eyes, so they are commonly used in personal care products such as shampoo, shower gel, and detergent.
Foam stability: compared with ionic surfactants, non-ionic surfactants can also produce stable foam in hard water.
Compatibility: They can be compatible with various types of chemicals, including other types of surfactants, making them very useful in formula design.
Cleaning ability: Non ionic surfactants have good cleaning ability and are commonly used in cleaning products.
Biodegradability: Many non-ionic surfactants have good biodegradability and are environmentally friendly.
Low temperature stability: They can also maintain stability at low temperatures and are suitable for cleaning agents that need to be used under low temperature conditions.
Common non-ionic surfactants include:
Alkyl phenol polyoxyethylene ethers (APEOs), such as nonylphenol polyoxyethylene ethers (NP EOs) and octylphenol polyoxyethylene ethers (OP EOs).
Fatty alcohol polyoxyethylene ethers (AEOs), such as sodium dodecyl sulfate (Laureth).
Polyoxyethylene fatty acid esters, such as polysorbate.
Polyethylene glycol fatty acid esters, such as carbitol.
Non ionic surfactants are widely used in fields such as cosmetics, pharmaceuticals, textiles, paints, cleaning agents, and agriculture. However, some types of non-ionic surfactants, such as APEOs, are gradually being replaced by safer and more environmentally friendly alternatives due to their environmental and health risks.
What is a water decolorizing agent?
KR-801 is a cationic polymer compound of cyanoguanidine series, which has various functions such as decolorization, flocculation, and CODcr degradation. It is mainly used to treat wastewater from high concentration and high chromaticity dyes, printing, and intermediate dyeing processes, especially for the treatment of wastewater from reactive dyes, acidic dyes, and dispersed dyes.
KR-801 water decolorizing agent can be used to treat industrial wastewater in industries such as textiles, printing and dyeing, pharmaceuticals, papermaking, and chemical industry, with a decolorization rate of over 95% and a CODcr removal rate of over 65%. When using, it is recommended to dilute KR-801 with 10 to 40 times water and directly add it to the wastewater. After stirring for a few minutes, precipitate or perform air flotation to obtain clear water after decolorization. In addition, adjusting the pH value of wastewater to 7 to 10 can improve treatment efficiency. When the color and CODCr value of the wastewater are high, in order to save treatment costs, KR-801 can be alternately used with polyaluminum chloride (PAC), but KR-801 and PAC cannot be mixed together. Whether to add polyaluminum chloride first or use KR-801 first should be determined based on laboratory testing and processing.

Application of DTPMPA in Multiple Industries
1、 Performance and Usage
DTPMPA is a non-toxic chaical substance that can dissolve in acidic solutions. It has excellent scale and corrosion inhibition effects and good taperature resistance performance. This substance can inhibit the formation of carbonate and sulfate scales, and exhibits better scale and corrosion inhibition performance than other organic phosphines in alkaline and high-taperature environments (above 210 ℃). In the field of water treatment, DTPMPA is widely used as a scale and corrosion inhibitor for circulating cooling water and boiler water. Especially suitable for alkaline circulating cooling water, it can be used as a pH regulator, and can also be used as a scale and corrosion inhibitor for oilfield water injection, cooling water, and boiler water with high carbonate content. In addition, DTPMPA can be used as a peroxide stabilizer, especially under high taperature conditions, which has a better stabilizing effect on hydrogen peroxide. It can also serve as a chelating agent in textile printing and dyeing processes, a dispersant for pigments, an oxygen delignification stabilizer, a carrier for trace elaents in fertilizers, and a concrete additive. In addition, it has also been widely used in fields such as papermaking, electroplating, metal pickling, and cosmetics. In addition, DTPMPA can also be used as a stabilizer for oxidizing fungicides.
2、 Usage
DTPMPA is generally used as a scale inhibitor with a concentration of 1-30mg/L, and as a cleaning agent with a concentration of 1000-2000mg/L; Usually used in combination with polycarboxylate type scale inhibitors and dispersants. When used in other industries, the dosage should be determined based on experiments.
3、 Packaging and storage
DTPMPA is packaged in plastic drums, with each drum weighing 30kg or depending on user needs. Store in a cool indoor place for a storage period of twelve months.
4、 Security protection
DTPMPA is acidic, so pay attention to labor protection during operation and avoid contact with skin, eyes, etc. After contact, rinse with plenty of water.
