Description

Technical Field

[0001] The utility model relates to the technical field of light sand - wrapped sand real stone paint filtration and packaging, and particularly relates to a pre - packaging filtration device for light sand - wrapped sand real stone paint. Background Art

[0002] As a new product, Zhenli Stone light real stone paint sand - wrapped sand (or a colorful finished product with color dots of 1.0 - 1.5 mm) is launched on the market. The construction appearance of the paint is an important indicator to measure the product quality. Compared with ordinary real stone paint, this product uses colorful dots instead of colored sand. Compared with ordinary colorful paints, this product has the characteristics of small color dots, low consumption, high sand content, and fast film - forming. During the production and stirring process, the color - matching time is long, and there are phenomena of easy film - forming and agglomeration, resulting in small agglomerations on the wall film appearance of the product.

[0003] Because this product is a new product, different from ordinary water - wrapped sand or water - wrapped water colorful products, it has small color dots, with the color dot size of about 1.0 - 1.5 mm, and the spraying effect is flat. The existence of slight impurities will also be more obvious in the spraying and wall - mounting of the light sand - wrapped sand real stone paint product. If the traditional filtration device is used for operation, the packaging efficiency is low. Content of the Utility Model
