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 Rucca Equipment in Pigment Dispersion and Grinding
In the traditional technology, the pigment dispersion and grinding process mainly uses the high speed disperser and bead mill, take the production of the color paste as an example: the concretely must include the dosing and weighing ---pre-mixing ---dispersion and grinding ---blending potting---filtration packing, these steps.
In the traditional technology,high speed disperser and bead mill have some disadvantages as below:
Disadvantages of batch disperser:
1.Batch type dispersion technology,long mixing time,and high energy consumption.
2.By pass area appears easily in batch dispersion process.
3.Many air bubbles,it affect the dispersion effect easily.
4.Capacity has been limited,high cost to improve it.
5.Energy input is not uniform,product quality is not stable.
Disadvantages of bead mill(grinding machine):bad dispersion effect,which brings down the production efficiency of bead mill,too much time spend on dispersion process,waste time and energy.
Rucca equipment in pigment dispersion and grinding process.
IDS integrative dispersion grinding system,in this system,the dispersion uses Rucca IDS inline dispersing system machine,this machine adopts innovative technology,its rotor and stator runs in high speed,the liquid is thrown out to create vacuum,and bring in the powder,make the powder and liquid mixing,with continuous inline dispersing effect,creates a high-gradient shearing to the powder,wets it instantly,causes every powder particle can be mixed into liquid totally and evenly,extremely improve the dispersion efficiency,save more than 50% energy.Effectively reduce the time of bead mill in the dispersion,improve production efficiency, the real realization of energy saving.
The system is a leader in the industry and has the following advantages:
1.Powder is wetted instantly,extremely improve the dispersion efficiency,save more than 50% energy.
2.Good dispersion effect,particle size is small and distribution is narrow.
3.No suction of extra air, and can quickly degassing, reduce the amount of defoamer.
4.More easy to wet powder, reduce the amount of wetting agent, dispersant.
5.Reduce the loss of powder, reduce the amount of filter dust consumption.
6.It is easy to realize CIP cleaning and the use of detergent is less.
7.Low viscous material can realize pump function,with extra pump,it can work for solid content over 80%.
8.Part material is optional depends on different product requirements.
Non-negligible explosion-proof design
If the ground product is an organic pigment, special attention should be paid to the characteristics that may cause the explosion. This involves critical energy, critical temperature, and KST values. According to these data, adequate protection must be provided when the limit is exceeded. All Rucca equipment support custom explosion-proof.
The pigment with high quality and special requirements can be produced by using suitable dispersing and grinding equipment, and the fineness and quality requirements of the product can be achieved. Such a dispersion and grinding process can also increase the value of the production enterprise products, reduce energy consumption and other production costs. Let Rucca equipment become the core competitiveness of your enterprise, LOOKING FORWARD TO WIN-WIN COOPERATION!
