In the history of the development of the paint industry, Coatings made of natural substances have experienced a long production history. At first, natural minerals and pigments were used as raw materials, and later on, petroleum, rosin, and insects were used as raw materials. Oil-based coatings and natural resin coatings are made from natural resins (including modified natural resins) based on glue and lacquer. After the Second World War, the raw materials for coatings were mainly coal chemical products. After the 1960s, petrochemical products were used as the main raw materials. The impact of the oil crisis in the early 1970s made people realize that paint raw materials should be sourced from multiple channels.
Automation of coating production and application
Production equipment tends to be sealed, pipelined and automated. Electronic computers are used in paint distribution, Synthetic resins and coatings are used in storage and transportation. Production and processing control are gradually becoming semi-automated and automated, and product packaging is also gradually automated.
Construction applications are gradually developing from manual operations to mechanization and automation. At present, electrostatic spraying, electrodeposition coating, electrostatic powder coating, etc. have been developed Yahei”>, robots began to be used in construction.
Develop solvent-saving, resource-saving, low-pollution Multiply paint
The solvent used in the coating forms a film and then evaporates into the atmosphere, causing‘ pollution and a waste of resources. Saving solvent is an important measure for coatings to save resources and reduce pollution. This promotes the accelerated development of water-based coatings, high-solid coatings and powder coatings.
