A team led by researchers at Virginia Tech University has developed the world's first soap made from plastic, according to a report in the latest issue of Science magazine. The new method could upgrade plastics into a high-value chemical called a surfactant.The wax produced by waste polyethylene and

After the defoamer manufacturer produces the defoamer for coating, in order to ensure the quality of the product, it is necessary to check the performance. The following six test methods can be used:1, the measuring cylinder method: add an appropriate amount of low-viscosity paint in the measuring c

Softener is a kind of chemical substance that can change the static and dynamic friction coefficient of fiber. When the coefficient of static friction is changed, it feels smooth and easy to move on the fiber or fabric; When the coefficient of dynamic friction is changed, the fine structure between

Cationic surfactants are ionized after their molecules dissolve in water, and the hydrophilic groups connected with the oleophilic groups are positively charged surfactants. Oleophilic groups are generally long carbon chain alkyl groups. Most of the hydrophilic groups are cations containing nitrogen
