Grease is an important process in leather processing, it can give the finished leather with soft, plump, elastic and other good hand feel and greatly improve its physical properties. Leather fat additive is generally composed of emulsifier, neutral oil and fat additive. The neutral oil in the fat ma

Since combustion is a complex oxidation process, in order to make it fully reactive and prevent coking, many additives are used in fuel oil. Some of them are directly involved in the reaction, and some are not directly involved in the reaction, but are used to improve the stability of the fuel oil a

Metal cleaning is an indispensable process in the metal processing process, such as cutting, electroplating, painting and other processes must be cleaned before the workpiece to remove rust, oil, scale, dust and so on. Metal cleaning agents can be generally divided into solvent and water based two c

1 Neutralization of surfactant in nitrocellulose brightenerNitrocellulose brighteners occupy an important and even dominant position in the top coating of leather, although there are many finishing materials such as proteins, polyacrylates, and polyurethanes competing with them. Surfactants play a d

Chemical composition: alkyl phenol polyoxyethylene etherType: Non-ionicAppearance: Yellowish to colorless viscous liquidHLB value: 12PH value: 5.0 ~ 7.0 (1% aqueous solution)Second, performance and use1, easy to dissolve in water, acid, alkali, chlorine, heat, hard water, metal salt resistance, with

Fatty alcohols are alcohols with aliphatic groups of 8 to 22 carbon atomic chains. Fatty alcohols usually have an even number of carbon atoms and a hydroxyl group attached to the end of the carbon chain.One of the raw materials of surfactants used in detergents. The general formula is ROH. The R of

Polyethylene glycol PEG is a polymer prepared by stepwise addition reaction of ethylene oxide with water or ethylene glycol as raw material. It is a white paraffin-like flake or powder solid, odorless or with weak odor. It is non-toxic, non-irritating, has good water solubility, and has good compati

In the production process of pesticides, penetrants are indispensable, and the quality of pesticide penetrants directly affects the control effect of chemicals, so what are the specific effects of pesticide penetrants? What are the common pesticide penetrant products?Pesticide penetrant action:1, im

(1) Fast penetrating agent not only plays a wet effect in ink, water-based gloss oil, grinding (pressing) gloss oil, but also has the viscosity of water-based ink and water-based gloss oil, which can not increase the thickener.(2) Fast penetrating agent can be used as wetting agent, emulsifier, leve

Surfactants have a series of physical and chemical effects such as wetting or anti-sticking, emulsification or breaking, foaming or defoaming, solublization, dispersion, washing, corrosion prevention, antistatic and so on, and have become a kind of flexible and versatile fine chemical products with
