1、 What is a white masterbatch?
White masterbatch refers to a basic material that can be used to prepare various colored coatings, plastics, and other products. Its main components are white pigments and diluents.
2、 Method for preparing white masterbatch
There are various methods for preparing white masterbatch, and the commonly used ones are as follows:
1. Mechanical mixing method: Mix the white pigment and diluent evenly in a high-speed mixer.
2. Solvent method: Dissolve the white pigment in an appropriate solvent, add a diluent, and stir to form a white masterbatch.
3. Dispersion method: Use a grinder to finely grind the white pigment, add a diluent, and disperse it into a uniform white masterbatch through a disperser.
3、 National standard regulations on white masterbatch
The national standards for white masterbatch mainly focus on color, transparency, reflectivity, and other aspects.
1. Color: According to national standards, the color of white masterbatch is white.
2. Transparency: According to national standards, the transparency of white masterbatch should not be less than 95%.
3. Reflectivity: According to national standards, the reflectivity of white masterbatch should not be less than 85%.
In addition, national standards also specify specific requirements for white masterbatch in different application fields. For example, in the paint field, white masterbatch is required to provide good covering and adhesion, while in the plastic field, white masterbatch is required to have good color and stability.
4、 The application of white masterbatch in different fields
White masterbatch is an important basic material that has been widely used in various industries. In industries such as construction, automotive, and aviation, white masterbatch is used to prepare materials for corrosion prevention, waterproofing, and insulation, which can effectively improve the performance and aesthetics of products. In the fields of food and cosmetics, white masterbatch is used to prepare products such as emulsions and powders, which can improve the quality and stability of products.
In short, white masterbatch is widely used as a basic material in various industries. The regulations on white masterbatch in national standards provide a legal basis for ensuring the quality and safety of products.
