In the glue coating industry, choosing the right mixing tank is crucial. This article will introduce to you how to choose a mixing tank scientifically and rationally, as well as the key elements that need to be paid attention to during the production process, to help the industry achieve production upgrades.


1. Material selection: 

Understand the different grades and characteristics of stainless steel, select the appropriate material according to the composition and characteristics of the glue paint, and ensure that the material of the mixing tank is compatible with the paint being processed to prevent chemical reactions or contamination. Generally choose 304 or 316 stainless steel.


2. Capacity and size: 

Choose a mixing tank with appropriate capacity according to production needs. Consider factory space and ensure the size of the mixing tank matches the existing work environment.


3. Selection of stirring method: 

According to the viscosity and particle size characteristics of the paint, select the appropriate stirring method to achieve the best mixing effect.

Common mixing methods include the following:

1)Anchor Stirrer

- Principle: The anchor mixer is designed like an anchor and is located in the center of the mixing tank. It pushes the liquid from the center to the outside through rotation, creating a strong horizontal stirring effect.

- Applicable scenarios: Suitable for paints and glues with high viscosity, which can effectively disperse solid particles evenly in liquids.

2)Paddle Stirrer

- Principle: Paddle mixers usually consist of flat-shaped mixing blades that stir the liquid through rotation. The stirring effect produced by this design is mainly vertical.

- Applicable scenarios: Suitable for low to medium viscosity liquids and can provide a more uniform mixing effect.

3)Frame Stirrer

- Principle: Frame mixers usually include one or more rectangular frames that circulate and stir the liquid through rotation. This design creates cyclic movement of fluid throughout the mixing tank.

- Applicable scenarios: Suitable for paints and glues that require large-scale, all-round mixing.

4)Helical Stirrer

- Principle: The blades of the ribbon mixer are spiral-shaped and rotate to produce rising and falling movements of the liquid, thereby achieving a mixing effect.

Applicable scenarios: Suitable for high-viscosity liquids, which can effectively lift the paint or glue at the bottom to the upper part of the tank to ensure thorough mixing.


4.Sealing performance

In the development and production of coatings, sealing performance is even more important. An efficient sealing system can reduce solvent evaporation, ensure the accurate ratio of coating ingredients, and prevent product waste caused by evaporation. The stainless steel mixing tank with excellent sealing performance can effectively reduce the impact of the environment on the coating formula and provide reliable guarantee for production. The main factors that affect the sealing performance of the mixing tank are the sealing structure and sealing material.

 

-Sealing structure: Choose a reliable sealing structure, such as mechanical seal or packing seal, to ensure that the mixing tank will not leak during operation.

-Seal material: The material of the seal should be corrosion-resistant, wear-resistant and high-temperature resistant to adapt to different working environments and material properties.


5. Stirring speed:

Different paint glues may require different stirring speeds. Make sure the mixing equipment you choose can handle the appropriate mixing speed required for mixing the paint.

 

6. Cleanliness:

Choose mixing equipment that is easy to clean to prevent cross-contamination of paint. Removable mixing equipment is usually easier to clean. The surface of the mixing equipment should be designed to avoid grooves, protrusions or irregular surfaces to reduce paint adhesion. The smooth surface facilitates cleaning operations and prevents the build-up of residue. Some mixing equipment uses special surface coatings, such as polytetrafluoroethylene (PTFE), to reduce paint adhesion and make it easier to clean.

 

7. Stirring speed:

Different coatings may require different stirring speeds. Some coatings require high-speed mixing to ensure thorough mixing, while others may require low-speed mixing to prevent foaming or excessive shear.

 

8. Temperature control:

If the paint is easier to handle at a specific temperature, consider choosing a mixing tank with temperature control. Make sure the mixing tank can withstand the required temperature range

 

9.Safety considerations:

Ensure that the design of the mixing tank complies with relevant safety standards and regulations.

Consider adding safety devices such as protective covers, emergency stop buttons, etc.

 

10. Cost-effectiveness: 

When choosing a stainless steel mixing tank, consider performance, durability and cost-effectiveness. Find a balance point to ensure that the selected equipment can operate stably in the long term and reduce production costs.
