But can be fully exerted only by matching with the shape of the building and the size and shape of the base material.
The interior wall coating has the advantages of simple construction, various colors, easy decoration of various ornaments, simple and elegant decoration effect, and is the most widely applied interior wall decoration material at present. The pigment is developed and produced from 80 years in China, dozens of models exist so far, the basic performances of the pigment are the same, and the pigment is basically composed of water, pigment, emulsion, filler and various auxiliary agents. However, the interior wall coating prepared from the emulsion, the auxiliary agent and the like has the defects of VOC emission, heavy metal content and the like.
Casein, also known as casein, is a casein product extracted from cow milk and products thereof. The casein is a white or yellowish odorless powdery or granular material produced and processed by fresh milk through the methods of centrifugation, degreasing, precipitation, drying and the like, is mainly used as a food additive or a quality modifier, is widely applied to the industries of food, medicine, tobacco, cosmetics, leather, light textiles, paper making and the like, and is an important food and chemical raw material. Casein generally refers to a mixture of many phosphoproteins secreted by bovine mammary glands. Molecular weight is approximately 57000-375000. Casein is present in milk at about 3% and accounts for about 80% of milk protein. Pure casein is white; is tasteless; odorless granular solid. The relative density was about 1.26. Insoluble in water and organic solvents.
