Recycled paint: English name of paint: paint or coating. Paint is a kind of chemical mixture paint that can be firmly covered on the surface of objects for protection, decoration, logo and other purposes. The book Paint Technology compared by the coating industry defines as follows: "Paint is a kind of material, which can be coated on the surface of an object with different construction processes to form a solid film with firm adhesion, certain strength and continuity. The film thus formed is generally called a coating film, also called a paint film or coating."
Paint recycling: other functions of paint:
Marking, antifouling, insulation, etc. For modern coatings, this effect is more and more important than the first two. Some modern coatings can provide a variety of different functions, such as: electrical insulation, conduction, electromagnetic wave, anti-static generation, etc; Anti mildew, sterilization, pest killing, anti adhesion of marine organisms and other biochemical functions; High temperature resistance, heat preservation, temperature indication and temperature marking, prevention of prolonged combustion, ablation and heat insulation and other thermal energy functions; Reflected light, light emission, absorption and reflection of infrared ray, absorption of solar energy, ray, logo color and other optical properties; Anti slip, self-lubricating, anti fragmentation splash and other mechanical properties; There are also various functions such as anti noise, vibration reduction, sanitary disinfection, anti condensation, anti icing, etc. With the development of national economy and the progress of science and technology, coatings will provide and play a variety of new special functions in more aspects.
In order to make the stable operation of ultrafiltration effective, good membrane pretreatment should be carried out. Walnut shell filter and sand filter are common physical processes of membrane pretreatment. However, some reasons will make its effect not reach the ideal state, such as the traditional sand filter and walnut shell filter, after a long time of operation, the sewage holding capacity will decline. If the membrane pretreatment is not done well, the oil content of the effluent will be relatively high, and then the ultrafiltration membrane will be polluted, thus reducing the service life of the ultrafiltration membrane and increasing the cost of ultrafiltration membrane treatment. The main factor restricting the application of membrane technology is membrane pollution. It is very necessary to control membrane pollution and extend the service life of membrane.
