How to choose grinding equipment in pigment production? Pigment as a kind of colorant,are widely applied in different industries,such as paint,coating,ink,plastic,textile,cosmetic,food and so on.According to the characteristics of pigment,we can divide colorants into two kinds:soluble pigment and insoluble pigment.Soluble pigment do not need to grind obviously,so we said how to choose grinding equipment in pigment production,generally means for insoluble pigment. Due to the pigment is insoluble, its color strength and chromaticity are directly affected by the size and shape of pigment particles. Therefore, the choice of a suitable dispersion grinding process will significantly enhance the pigment in the basic materials on the pigmenting property. Application of Rucc
In recent years, the new energy industry has developed very rapidly in our country. The rapidly developing new energy field has promoted the growth of battery demand. Especially new energy vehicles can be described as "hot". Rucca has spared no effort in the development of new energy fields in recent years. The main products are concentrated in powder conveying and metering, high-viscosity mixing system, powder surface modification equipment and ternary precursor co-precipitation reaction device, wet process dispersing grinding equipment and Ids Inline Dispersing systems. 一、Powder conveying and metering, production process informatization There are many kinds of products produced by modern enterprises, and it is more and more difficult to adjust the
In the process of daily paint and coating production, it is usually the solid pigment and liquid paint paste and various additives, small materials, etc. to be mixed and stirred, so that the product has a certain fluidity, which is convenient for entering the next step of more refined grinding and dispersion. This mixing of pigmented paint production ingredients is also known as agitation or pre-dispersion. The role of pre-dispersion is as follows: 1. Mix all kinds of pigments and liquid paint paste evenly 2. The paint paste replaces the air adsorbed on the surface of some pigment particles, so that the pigment can be partially moistened 3. Make the large pigment particles initially depolymerize to shorten the working time of the next grinding and dispersion and improve the dispersion efficiency. This

High Speed Disperser 1. Overview High speed disperser, as the name suggests, its main working part is the high speed operation of the dispersion plate, and the most commonly used stirring part of the high-speed disperser used in our daily production is the serrated disc impeller (commonly known as the dispersion disc, dispersion blade, etc.), the dispersion disc is driven by the high-speed rotating dispersion shaft. The high-speed rotation of the dispersion disc causes the paint paste in the cylinder to show a rolling circulation, and the power-sufficient equipment will produce a large whirlpool. The powder or pigment floating on top of the paint paste will soon descend to the bottom of the vortex with a spiral. In the area of 2.5-5 cm at the edge of the dispersion disc, a turbulent flow zone is formed. In
Location:Malaysia Customer requirements:Dispersion of outdoor wall paint,the purpose is saving energy. Effect description:The fineness of outdoor wall paint is 45um,solid content is 65%,8500kg slurry for one batch,in traditional process,one 90KW high speed disperser need to run 1.5 hours to finish,however,of Rucca new technology,only need one 45KW inline dispersing system machine to run 1 hour,besides,the fineness is better.
Location:Kenya Customer requirements:to produce white ink,improve capacity. Effect description:In production of normal white ink,use IDS inline dispersing system machine to dispersing titanium dioxide(TiO2,solid content 35%),1860KGS titanium dioxide only need 13 minutes to finish,powder induction speed reach to 150kg/min,the fineness can reach to 20-30um.
Location：Turkey Customer requirements:High speed dispersion mixer to dispersing 2000L water based suspension concentrate evenly before grinding,to reduce particle size of material concurrently,then transfer to bead mill,the final particle size need to reach to D90=2um,moreover,improve the capacity. Effect description:Jet mixer can mix water based suspension concentrate(solid content=50%) evenly about after 45min in the speed of 1470rpm,then grind slurry in bead mill,the effect will improve,at same time,the problems of powder coating, agglomeration and packing in suspension agent are thoroughly solved, and the final particle size reached to D90=2um as required by customers.
Location:China Customer requirements:To dispersing silicon which use as flame retardant material of battery,the final particle size of material is required to nanometer,meanwhile,to solve the dust contamination in workshop. Effect description:From powder suction to grinding dispersion,only need 10 minutes,can make the particle size of silicon(solid content 30%)to reach to D90=600nm.Silicon powder be inducted to IDS inline dispersing system machine and dispersing,then grinding by bead mill,to stabilize the product.In this system of Rucca,it need only one bead mill,that will save one pass grinding process.
