The black mother for PVC raw materials is an additive that can turn the color of polyvinyl chloride (PVC) resin into black. It is made of some special chemical raw materials, which can stably disperse pigments in PVC resin and maintain its long-term stability.
This black mother has a very important role in the production of PVC products. PVC resin itself is white, but in many applications, it is necessary to change its color to black, such as water pipes, wires and cables, automotive interiors, building materials, and so on. At this time, it is necessary to use black mother, which can effectively change the color of PVC products to make it more in line with the requirements of use.
The production process of PVC raw material special black mother needs to go through multiple processes, including raw material screening, mixing, heating, cooling, crushing and so on. It is necessary to control various parameters in the production process to ensure the quality and stability of the product.
The performance of black mother is mainly affected by pigment, dispersant, carrier and other factors. The choice of pigment should meet the product performance requirements, and pay attention to the stability and light resistance of the pigment. The dispersant should be able to uniformly disperse the pigment in the PVC resin to avoid pigment precipitation and aggregation. The carrier must be compatible with the PVC resin and will not affect the physical and mechanical properties of the PVC resin.
The use of black mother is generally between 1-5% in PVC resin, and the specific use amount should be determined according to product requirements and production process. When using black mother, it needs to be fully mixed to ensure the color stability and consistency of the product.
The special black mother for PVC raw materials is a very important additive, which can effectively change the color of PVC products and make them more in line with the requirements of use. In the process of production and use, it is necessary to pay attention to the control of various parameters and the stability of product quality.
