The lab model Double Sigma Blade batch systems provide complete, homogeneous mixing, even in small quantities.

 

The mixing action is a combination of bulk movement, shearing, stretching, folding, dividing, and recombining as the material is pulled and squeezed against blades, saddle, and side walls. Continually new layers of material are compressed and folded over one another and are subjected to shearing forces.

 

Main features :

  • Wide range of sizes from 2-50 litre working capacity.
  • Adjustable blade arm rotation
  • Quick disassembly of the through-ends opposite the drive and blades for easy cleaning.
  • Stainless steel construction.
  • Simple installation – only a single power cable.
  • Stainless steel with sight-grid cover for product viewing during mixing.
  • Vacuum design available.

Mixing of Silicone Rubber

Tags : 

How to mix silicone rubber ?

the mixing of silicone rubber. Mixing of tough masses such as rubber require special equipment such as kneaders. These mixers need to be robust in construction and consume high power.

silicone sigma mixer

Usage:

This kind machine is mainly used in high viscosity product Resins,Sealant,Silicon rubber,Glue/adhesive,Paint,Dye,  BMC/CMC,  high voltage insulating silicone rubber Sigma Kneader , Pigment,Plastics,Batteries,Tooth paste,Clay etc.

Description:

This machine comprises of a double ‘U’ shaped container welded and machined together inside which rotates two ‘Z’ shaped sigma blades in opposite directions. The clearances between the walls and the container are kept to a minimum to ensure maximum efficiency in kneading and mixing. The shafts of the sigma blades are fitted in bearing blocks which are each provided with roller bearings, steel glands/teflon rubber seals for smooth and leakless operations. The kneader is mounted on a sturdy base frame fabricated out of ISMC sections and are free from vibrations. For cooling and heating jackets are provided.Machine equipped with suitable capacity motor & gearbox decided as per characteristics of the product & process. Equipment is provided with Jacket arrangement for heating or cooling applications. We manufacture Sigma Mixer Kneader in capacity ranging from 5 liters up to 3000 liters.

Sigma Mixer Working Principle

Silicon compounding sigma mixer

 

Start the motor,add the material,after adding material,clean the foreign matter on the cylinder port.It takes Hydraulic Dumping up cylinder Discharge the material,it is rapid and clean to discharge.

Advantages:

1.Excellent sealing performance(copper sealing ring)

2.Simple installation-only a single power cable

3.No leakage of powder /oil-proof

4.Automatic and manual interaction

5.heating quickly, resistance of high temperature and corrosion, sanitation, environment-pollution-free, automatic heating without boiler and convenient to use etc

Production of Hot Melt Pressure Sensitive Adhesives

Production of Hot Melt Pressure Sensitive Adhesives

Hot Melt Pressure Sensitive Adhesives (HMPSAs) are composed of Styrenic Block Copolymers (SBC), tackifier, mineral oil, a small amount of antioxidant, and other special additives – such as filler, colorant, and low molecular weight polymer if needed. Most of these ingredients are thermoplastic materials and require a heated environment to mix them together.

Many different types of mixers are available for mixing HMPSAs. Following are two commonly used techniques.

Vertical Reactor mixer. Use of Vertical Reactor is the most economic technique for making HMPSAs. Low molecular weight ingredients, oil and/or tackifiers, must be charged first for this type of mixer. Otherwise, the high torque generated from SBC may damage agitators. Commonly used charging sequence is as follows: 1) mineral oil and antioxidant, 2) tackifiers, and 3) SBC. A good vertical mixer should provide the following features: 1) excellent jacketed hot oil circulation to provide quick heat exchange, 2) adequate agitating configuration to reduce mixing time, 3) scrappers to remove adhesives off the wall and bottom of mixing vessel. This will improve heat exchange and minimize char formation, 4) vacuuming system to avoid oxidation during mixing.

Horizontal Sigma mixer (Sigma blade mixer or Kneader). This type of mixer is normally accompanied with an extruder for easy adhesive discharging purpose, named mix-truder. The mixing sequence of a horizontal mixer is just opposite to that of a vertical one. Generally, the sequence is as follow: 1) SBC plus antioxidant, 2) tackifiers, and 3) mineral oil. It is more efficient to produce a batch of HMPSA with a horizontal mixer versus a vertical one due to its faster heat exchange and higher shearing torque. Additionally, a horizontal mixer can handle more viscous materials with its heavy duty rotor. It is important to point out that tackifiers must be added slowly, portion by portion, after the SBC is fully masticated. Otherwise, the molten tackifier will function like a lubricant to the SBC. This will greatly reduce the shearing efficiency of rotor and result in a poor mixing. Since, the mixing sequence starts with SBC, if the mixing chamber is not under a vacuum environment, the SBC tends to oxidize with surrounded air or oxygen disregarding the addition of antioxidant.

In summary, the vertical mixers offer the following two advantages:

The system is much easier to pull vacuum during mixing. HMPSAs made by this technique normally offer better aging performances compared to those made with a horizontal mixer.
The material charging sequence is more flexible. There is no need for a skillful labor working on a vertical mixer.

The disadvantages of vertical mixers are:

It is somewhat difficult to produce very high viscosity products due to its lower shearing torque.
The heat exchange is somewhat slow. The total mixing time is therefore longer than those made with horizontal mixers.
