The molecular structure of surfactants is amphoteric One end is a hydrophilic group and the other end is a hydrophobic group.1 Hydrophilic groups are often polar groups, such as carboxylic acids, sulfonic acids, sulfuric acids, amino or amine groups and their salts, and hydroxyl groups, amide groups, ether bonds, etc. can also be used as […]

It is found that fatty amine type nonionic surfactants can play a good effect on the surface treatment of pigments, the reason why they can play this good effect is that: these surfactants can be adsorbed onto the surface of pigments by forming hydrogen bonds with nitrogen on the surface of pigments through one H

Paper is made from pulp. Pulp is made from certain plants, such as wood, grass, cotton as raw materials, using chemical or mechanical methods to remove all or most of the impurities, to obtain a pure or nearly pure plant fiber pulp. Pulp in addition to the main component of the composition of the fiber

Dishwasher consumables classification. There are generally 4 categories. 1、Dishwashing cleaning class – dishwashing powder / dishwashing block / dishwashing gel / dishwashing liquid This is the most important consumable for dishwashers, which is used every time you wash dishes, and is responsible for removing grease and stains and cleaning dishes. Since dishwashers cannot use traditional

Solvent and thinner are two words we hear a lot, but sometimes it feels like there is no difference. 1、The basic concept of solvents and diluents solvents and diluents are chemicals that can reduce the viscosity of the resin system, make the resin and other components better mixed, or make the adhesive better applied to

The compatibility of fresh concrete has a very great influence on the pumpability, construction performance, mechanical properties and durability of the concrete after hardening, and the compatibility of fresh concrete depends to a large extent on the air content of the concrete. In the actual construction, the best range of air content of concrete should

The laundry gel can be used by grabbing one directly with clean hands and throwing it into the washing machine, and then selecting the appropriate laundry mode to start washing clothes. The laundry gel has multiple washing effects and is much better than laundry detergent, which makes it popular among people. We usually add detergent

The HLB value of surfactants is related to their applications: surfactant molecules are amphiphilic molecules with both hydrophilic and lipophilic groups, and different types of surfactants have different hydrophilic and lipophilic groups, and their hydrophilicity and lipophilicity are different. The hydrophilicity of surfactants can be measured by the hydrophilic and lipophile balance values (HLB), which
