iHeir-JS(117) is a new generation of environmentally friendly anti-mold agent with nitrogen-containing heterocyclic phenol compound as active ingredient, which has anti-mold effect for most industrial products and has superior anti-mold stability and permanence.
It is widely used to protect PVC, PU, silicone resin, polyolefin, polyester, thermoplastic elastomer, rubber and other polymers from mold erosion.
Types of antistatic agents
There are many classification methods for antistatic agents, and they can be divided into ionic and non-ionic according to the form of their particles after being dissolved in water. The ionic type dissolves in water and ionizes ions, while the non-ionic type does not ionize. According to the electronegativity of the dissociated surface-active ions, the ionic type can be divided into cationic, anionic and zwitterionic.
According to the characteristics of antistatic agents, antistatic agents are divided into two categories: hygroscopicity and polarity. Hygroscopic substances can absorb water vapor in the atmosphere and form a thin conductive layer on the surface of the coating, so that electrostatic charges are easy to leak. Such substances are usually long-chain non-ionic surfactants. The main disadvantage is when the climate is dry. The effect is significantly worse. Polar substances themselves are very good conductors, and can also form a conductive layer on the surface of the coating. Its effect is also related to atmospheric humidity, but it still has a good antistatic effect in dry climates. This type of substance is mainly cationic surface Active agents are commonly quaternary ammonium salts.
Comprehensive ionic and chemical structure, current antistatic agents are generally divided into anionic, cationic, nonionic, amphoteric and other types. Antistatic agents here involve various types of compounds. The main ft wax uses features and compound types are as follows And so on to introduce separately.
Anionic antistatic agent
Anionic antistatic agents include higher fatty acid salts, alkyl phosphates, alkyl sulfate ester salts and sulfonate salts, etc. They are mainly used as textiles and chemical fiber oils, finishing agents, and are most used as polymer antistatic agents. The undoubtedly alkyl sulfonate compounds.
