Description
Technical Field
The invention relates to the technical field of automobile cleaning agents, and particularly relates to an environment-friendly efficient anti-corrosion automobile hub cleaning agent.
Background
The organic cleaning agent is different from the inorganic cleaning agent simply in that the organic cleaning agent is a cleaning agent made of a carbon-containing compound, and the inorganic cleaning agent is a cleaning agent made of a carbon-free compound, so that the organic cleaning agent and the inorganic cleaning agent belong to inorganic substances. There are many methods for classifying cleaning agents, and these methods are different from country to country, and we generally classify cleaning agents into three categories, i.e., water-based cleaning agents, semi-water-based cleaning agents, and non-water-based cleaning agents. The water-based detergent is prepared from surfactant (such as sodium alkylbenzenesulfonate and sodium fatty alcohol sulfate), various assistants (such as sodium tripolyphosphate) and assistant, and can reduce the surface tension of aqueous solution and increase detergency when washing dirt on object surface. The detergent is divided into solid detergent and liquid detergent according to the appearance form of the product. The solid detergent has the largest yield, is customarily called washing powder and comprises fine powder, granules, hollow granules and the like. There is also a paste detergent, also known as laundry cream, in between. Different synthetic detergents have different production processes, among which solid detergents are the most complicated. The hollow granular solid detergent is produced by high tower spray drying process including the steps of preparing slurry, spray drying, wind ageing and packing. The liquid detergent is easy to manufacture, and only the surfactant, the auxiliary agent and other additives and the treated water are fed into a mixer for mixing.
The water-based cleaning agent is widely applied due to environmental protection, in the prior art, in order to meet the requirement of environmental protection, part of the cleaning agent utilizes 4A zeolite to replace sodium tripolyphosphate as a builder, but the binding speed of the 4A zeolite and calcium magnesium ions is low, the binding capacity of the 4A zeolite and the magnesium ions is weak, and water cannot be well softened, so that the cleaning effect of the cleaning agent is reduced.
Therefore, an environment-friendly high-efficiency anti-corrosion vehicle hub cleaning agent is provided to solve the problems.
