Influence of chemical fiber masterbatch on polypropylene quality?

With the rapid development of China's economy, the chemical fiber masterbatch industry is also with the development of the development of the relevant industry, and the chemical fiber grain production technology has also been unprecedented progress, and the application field is constantly expanding. However, due to the impact of Chinese traditional market competition model, product competitiveness is not strong, especially in quality requirements. Especially the polypropylene manufacturers, more focus on the effects of chemical fiber masterbatch quality on polypropylene quality.

Dispersion of chemical fiber masterbatch in polypropylene fibers

 Apropylene fibers with various colors, is a uniform dispersion of pigment particles in polypropylene fibers, and the key is that the pigment particles are sufficiently refined, and are uniformly distributed (mixed) in the polypropylene fibers. Refining dispersion is to break the coagulating or agglomerate of the pigment so that the particles are smaller, and the key is to uniformly disperse, the desired effect on the color, transparency, gloss, fiber strength, elongation, and aging of the polypropylene fibers. Sex, electricity rate, etc. have an impact.

 Singlely, the particle diameter of the pigment is less than 1 um can be used for fiber or ultra-thin films, and greater than 5 um can cause no gloss, greater than 10 um, causes spots, strips, and granular diameter The fracture strength of large fibers, the elongation continuously decreased. The fine colored force is so strong, the better the dispersion, and the particle size is small to increase the surface, resulting in an increase in the covering force.

Since the pigment particle state has three types of native particles, the cohesion, the agglomerates, and the monologically pigment particles are particles (about 75-250 um) that are larger than the organisms, so the dispersion is required, and the dispersion of the so-called pigment is The process of pulverizing the regiment.

The dispersion of the pigment is firstly the wetting agent wetting pigment, covers the surface of the pigment, reduces the cohesiveness between the pigments, reducing the energy required to break the pigment coat, followed by the pulverization of the pigment, and the leading pigment particles The free movement (impact stress) and the pigment coat were broken by shear stress of the surrounding medium. After the pigment is dispersed, the particle size is reduced, the surface area is increased, and the free energy of the pigment has also increased the discolity of the pigment, so that the coating treatment of a single step in the surface of the pigment, reduce the new formation The interface surface can prevent re-aggregation, and then the pigment is mixed in the melt, which is uniformly dispersed into a material that needs to be colored in the melt.

Yantai Bright Color Plastics Technology Co., Ltd. was founded in 2005 and is located in the Shandong Peninsula, which is famous in the world-famous Shandong Peninsula. Kili). More than 60 kilometers away from Yantai, Qingdao Airport is only one hundred kilometers, and the traffic is very convenient. It is a comprehensive high-tech enterprise specializing in production, research and development, sales, masterpieces, and plastic machinery;

The company's masterbench products use high-quality imported, domestic raw materials and pigments, using domestic and foreign advanced wet ultra-fine grinding process technology, the quality is stable and reliable, the product has been used by many high-end customers at home and abroad; More than 5,000 tons of production capacity.
