Problems solved by technology

Those skilled in the art know that in addition to the basic components of the paint, the paint generally also includes pigments to obtain the desired color, but due to the particularity of the dry powder paint product (such as multi-color varieties, high color uniformity requirements, and many changes in raw material types) , large differences, etc.), different batches of dry powder coatings are prone to poor color chroma
The existing production process of dry powder coatings generally adopts a batch-mixing packaging process, and the differences between different batches are marked separately. This batch packaging method has disadvantages such as low production capacity and poor color management.

Abstract

The invention provides a device for producing dry-mixed coating mortar with controllable whiteness and a method for producing the dry-mixed coating mortar with controllable whiteness by using the same. The device comprises the following parts: a, a first metering device, an aggregate metering device and a white pigment metering device; b, a first mixing device and a second mixing device, wherein a feed inlet of the first mixing device is connected with the first metering device and the aggregate metering device and a feed inlet of the second mixing device is connected with the white pigment metering device; and c, a material conveying system, wherein the material conveying system sends a mixture obtained by the first mixing device into the second mixing device and the material conveying system is provided with a whiteness detection device or is provided with a sampling port for sampling in the whiteness detection. The device for producing the dry-mixed coating mortar with controllable whiteness, which is provided by the invention, can be a full-closed system. According to the invention, by carrying out online monitoring on whiteness and carrying out secondary mixing on a white pigment, whiteness of each batch of products is basically kept consistent; and production quality can be controlled and yield is improved.

Description

technical field [0001] The invention relates to a production device for mortar, in particular to a device capable of continuously and high-capacity production of dry-mixed finishing mortar with controllable whiteness, and a method for using the device to produce dry-mixed finishing mortar with controllable whiteness method. Background technique [0002] Architectural coatings mainly refer to coatings used for building exterior walls, interior walls, ceilings, floors, etc., which have decorative, protective and residential performance improvement functions. Benzene substances, formaldehyde and other organic volatiles, organic solvents, and heavy metals in early paints have caused serious pollution to the environment and humans, and there is a risk of pollution in every link from production to use. With the advancement of technology and people's emphasis on pollution, the paint industry has entered the era of "water-based paint" from the "oil-based paint" era. [0003] At pr...
