car water washer
Automated car washes come in several varieties, including touchless and friction car wash systems. Touchless car washes use high-pressure water jets and powerful detergents to clean vehicles without direct contact, reducing the risk of scratches and paint damage. These systems are ideal for customers who prioritize vehicle care and want a quick wash without entering the equipment. On the other hand, friction car washes use soft cloth or foam brushes that gently scrub the vehicle's surface, providing a more thorough clean while still maintaining care for the paint.

The degree of substitution (DS) of HEC, which indicates how many hydroxyl groups have been replaced by hydroxyethyl groups, can be controlled during production to tailor the properties of the final product. Higher DS values generally lead to increased solubility and viscosity. After the reaction, the HEC is purified and dried to produce a fine white powder that is easily reconstituted in water.
