With the rapid development of Chinese economy, the masterbatch industry is also accompanied by the development of related industries and significant development, masterbatch
Grain production technology has also been an unprecedented increase, masterbatch applications are constantly expanding. However, due to Chinese tradition
The impact of market competition model, often always the pursuit of "low-quality, low-cost, use"
, Resulting in lower production and masterbatch applications not
Stable enough, the quality of low-grade products less competitive, this problem has been widely recognized in many applications masterbatch manufacturers,
Especially for high quality polypropylene manufacturers pay more attention to the impact on the quality of masterbatch polypropylene Quality. To this end, according to the polypropylene fiber
Influence requirements of industry associations, quality of masterbatch for polypropylene
A masterbatch dispersed in polypropylene fibers

Polypropylene fiber with a variety of colors, is caused by the pigment particles are uniformly dispersed in polypropylene fibers, the key is a pigment
Particles sufficiently refined and uniformly distributed in polypropylene fibers
(mixing)
.
Refinement dispersed pigment particles is sufficiently refined and polypropylene
The fibers are uniformly distributed (mixed)
. Refinement is dispersed pigment agglomerates or aggregates crushed to particles to a minimum, and
The key is uniformly dispersed, the dispersion effect of color on the colored polypropylene fibers, transparency, gloss, fiber strength, elongation,
Aging resistance, electrical etc influential female rate.
Generally, the pigment dispersion of particle size less than
1um
It can be used for fibers or thin films, and more than
5 um
Will lead
Fiber matte, more than
10um fiber surface will lead to spots, streaks, and the particle size increased with fiber breakage
Strength, elongation declining. More fine particle coloring stronger, better dispersion, while the smaller particle size of the surface increases, resulting in
Hiding power increases.
Because the pigment particles have a primary particle state,
Aggregates,
Aggregate three, and general merchandise than the pigment particles is also aggregates
Large particles (about
75-250um), it must be distributed processing is the so-called pigment dispersion of the pulverized refined over Aggregates
Away.
Pigment dispersion, first with a wet pigment wetting agent, coated on the surface of the pigment, the pigment so that the cohesion between the reduction, reduced break
Broken pigment aggregates the energy required, followed by crushing of the pigment, the pigment particles leading free movement between (impact stress)
       With the rapid development of Chinese economy, the masterbatch industry is also accompanied by the development of related industries and significant development, masterbatch production technology has also been an unprecedented increase, masterbatch applications are constantly expanding. However, due to the influence of traditional Chinese model of market competition, often always the pursuit of "low-quality, low-cost, can" lead to downstream applications masterbatch production is not stable enough, the quality of low-grade products less competitive, this problem has been many applications masterbatch manufacturers widely recognized, especially for high quality polypropylene manufacturers pay more attention to the impact on the quality of masterbatch polypropylene quality. To this end, according to the requirements of polypropylene fiber industry associations, to discuss the impact of the polypropylene masterbatch Quality. PP masterbatch

  A masterbatch dispersed in polypropylene fibers

         Polypropylene fiber with a variety of colors, is caused by the pigment particles are uniformly dispersed in polypropylene fibers, the key is fully refined and pigment particles distributed (mixed) evenly in the polypropylene fibers. Refinement dispersed pigment particles is sufficiently refined and distributed (mixed) evenly in the polypropylene fibers. Refinement is dispersed pigment agglomerates or aggregates crushed to particles to a minimum, but the key is uniformly dispersed, the dispersion effect of colored polypropylene fiber color, transparency, gloss, fiber strength, elongation, resistance to aging , overcast rate etc affected. PP masterbatch

        In general, the pigment dispersion can be used for particle size less than 1um fibers or thin films, and will lead to greater than 5 um fiber matte, it will lead to greater than 10um fiber surface spots, streaks, and with increasing particle size fiber breaking strength, elongation declining. More fine particle coloring stronger, better dispersion, while the smaller particle size of the surface increases, resulting in increase opacity. PP masterbatch

         Because the state of the pigment particles have a primary particle aggregates, aggregates three, and general merchandise pigment particles are larger than the aggregate particles (about 75-250um), it must be distributed processing, so-called pigment decentralization is to reunite body shredding process refinement. PP masterbatch

          The pigment dispersion is first wetted with a wetting agent, a pigment, a pigment in the surface coating, so that the cohesion between the pigment reduces, reducing fragmentation energy required pigment aggregates, followed by crushing of the pigment, the pigment particles leading between freedom of movement (impact stress)
