What is Powder Surface Coating Machine?
The Brief Introduction of Powder Surface Coating Machine
The mineral powder surface coating machine is widely used in the fields of non-metal stuffing or pigment like plastic, rubber,ashesive, macromolecule materials, high polymer composite, functional materials and dope industries. Which is an outcome of the development of new and high technology nowadays, It can only improve the compatibility of both non-organic mineral stuff and organic high polymer, enhance binding force of interfaces, rise the mechanical strength and comprehensive ability, but also increase the stuffing ability of powder, save product cost and add special physical and chemical property to the product to some extent. In order to solve the above mentioned problems in production, our company designed and produced CLG series powder coating machine afetr several years of research and update.
The Application of Powder Surface Coating Machine:
Provided with the unique chamber design, both modification and depolymerization functions, the machine is applicable to modify various materials. It can reach excellent surface modifications for such materials as heavy /light calcium carnobate, kaolin, talcum, wollastonite, mica, white carbon black, zinc oxide, alumina, silicon powder, graphite, magnesium-hydroxide, barium sulfate, illite claystone and pyrophylite, hexagonite and etc.
Powder Surface Coating Machine Components:
1. Hopper: materials enter into hopper from silo or bags. Humidity of feeding materials should be less than 0.5%.
2. Conveying device: double screws and adjustable speed ensure the stability of material flow.
3. Agent adding system with temperature control:
Automatic temperature control system, free setting of melting temperature, suitable for various modifying agents in both solid and liquid form.
4. Main machine: Consisting of 3 modifying rollers in triangle form, compact design, high efficiency and stable running.
5. Cyclone dust collector:diffusion type
6. Impulse type bag dust collector: new generation pleat filter, with the advantage of little space, large filtration area, high dust removal efficiency and easy cleaning.
The working principle of Powder Surface Coating Machine:
The powder surface treatment is mainly completed by means of three modifying roller. The dry powder and dosed agent are put into the modifying rollers simultaneously. With high speed rotation, the powder and agent is running in the form of fluidizing vortex. The modification is going on with the heat generated by high speed shearing, colliding and friction among the rotor, stator and the powder.
The working features of Powder Surface Coating Machine:
1. Continuous operation, large capacity, suitable for industralized production in various scale.
2. High efficiency and less consumption of modifying agent, high covering and active index of powder, energy saving.
3. Both modifying and dispersion function, suitable for any fine materials, special active effect for material with small proportion and big cubage weight like white carbon, mica powder and talcum powder.
4. Powder and agent mixing and running in high speed and vortex, high modifying efficiency, with little change of granulate shape.
5. Running in negative pressure working condition, air tight, no dust leakage, no pollution, good operation condition, low labor intensity.
6. Operating in heat and cold conditions, no additional heating or cooling system required, esay operation.
7. Independent fluid and non-fluid agent adding system for continuous, stable and evenly operation.
Evaluation Method of modified Powder Surface
1. Active index
H=Weight of floating part in sample/total weight of sample
2. Measuring contact angle
3. Surface strength(surface tension)
4. Surface covering rate(diffusing reflection Fuliye divert spectrum method)
Titanate Coupling Agent
The basic types are composite and coordination.
The dosage is 0.1%-0.3% as stuff or pigment
Silane Coupling Agent
It is a low molecule organic silicon compound with special structure, used for surface treatment of non-organic mineral stuff or pigment.
There are more non-organic reaction points for coupling agent
Which can enhance the interaction of surface between no-organic stuff and pigment. It is divided into 7 types, applicable respectively to surface treatment of polyolefin, polyester epoxy resin, nylon, acrylics resin, polyurethane, synthetic rubber and other non-organic stuffing materials.
Organic Chromium Couple Agent:
The coupling effect is better in glass-fiber reinforced plastics.
Surfactant
a. Fatty acid and salt; b.Amine salt; c. Nonionic surfactant.
Organic-silicon
The main items are polydimeth siloxane,organic modified siloxane and high polymer of organic silicon and arganic compound. The organic silicon for arganic stuff or pigment is usually polymethy siloxane with active radicals.
Saturated Organic Acid And Organic Oligomer
Organic Surface Modifying Agent
