Problems solved by technology

[0002] Clay is a muddy plastic solid with certain adhesive properties. This type of plastic solid is generally composed of solid or liquid adhesives with adhesive properties and powder fillers with certain functions, and may also add appropriate pigments and auxiliary materials. There are many types of cement, including acid-resistant cement, corrosion-resistant cement and waterproof cement. At present, the most widely used in the market is waterproof cement. Waterproof cement is mainly due to its good waterproof effect, convenient construction, high temperature does not flow, good bonding performance, low temperature It has the advantages of not being brittle and cracked, and is widely used in industrial plants and civil building roofing projects with various slopes. It can also be used for the connection and unsealing of canals and pipelines, as well as the joints of multi-storey plants and underground oil pipes. Waterproof cement is used in production. Due to the lack of production technology, the degree of choice is very low, and the production method and pollution produced during production cannot be guaranteed
