Reverse osmotic dirt is a chemical for water treatment and membrane separation. It is mainly used to prevent the reverse osmosis membrane from being damaged due to dirt and sediments in water. Under the correct and appropriate concentration, reverse osmosis resistants are usually safe to the human body and do not cause direct damage to…
Oil overflow dispersers are chemicals used to deal with oil pollution incidents in waters such as oceans and lakes. The main component can include the following: Surface active agent: Surface active agent is one of the main ingredients of oil -spill dispersers, and they have the ability to reduce liquid surface tension. Common surface active…

Forramine chelating agent is a chemical for removing iron ions in the water. They form a stable partial complex with iron ions, wrap the iron ions in it, make them lose their activity and become insoluble in water, thereby achieving the purpose of removing iron ions. The following are several common dehumanamide chelating agents: EDTA…
High -efficiency dispersing agent is a commonly used surfactant, which is mainly used to disperse solid particles into liquid medium to prevent it from condensing and precipitating. The specific ingredients of high -efficiency dispersing agents can vary depending on different products, but the following types of compounds are often used as the main component of…
