Rubber and Plastic Test Machine

Introduction:

Open mill is short for open plastic refining machine, the main working parts are two different inward rotation of hollow roller or drilling roller, two roller sizes are generally the same, each at different speeds relative rotation, raw rubber or rubber material with the rotation of the roller is involved in the gap between two rollers, by strong shear and achieve the purpose of plasticizing or mixing. Open mixer is also used for plastic processing. The open mixer is a kind of mixing plastic equipment which is used earlier in the plastic production factory. On the calendering machine production line, the mixing machine in the calendering machine before, after the mixing machine, the role is to mix evenly mixed raw materials for mixing, plasticizing, for calendering molding plastic products to provide more uniform mixing plastic melting material.

Features:

Small open mixer is for factories and scientific research institutions, colleges and universities experiment, formula research and development. Its structure design is simple, covers an area of small, easy to operate, easy to handle, high safety factor, convenient maintenance and disassembly, domestic small open mill technology has been in quite mature level, has been recognized by domestic colleges and universities scientific research institutions, and has been exported to foreign markets.

Technical parameters:

Applicable products:

 silicone rubber products, plastic products, polymer materials, engineering materials, etc.

Small open mixer is suitable for color matching, dispersion, PVC dynamic aging, stability experiment, etc., of pigments, rubber, plastics and other polymers.

Colleges and universities, scientific research institutions: research and development of new materials, teaching use, formula improvement

Plastic industry: mixing color, plate sample

Pigment industry: color matching sample, comparison film, testing dispersion

Chemical stabilizer: stability experiment, dynamic aging experiment

Rubber industry: rubber mixing, thin pass, modification

Operation precautions:

1. Before operation should wear good gloves, no waist rope, belt, rubber, etc. It is strictly prohibited to wear clothes

2. before operation should check the size of gear and roll between the sundries. Test whether the emergency brake is sensitive and reliable.

3. If more than two people operate, they should respond to each other. Only after confirming that there is no danger can they start

4. adjust the roller distance around the same, it is strictly prohibited to roll operation, to avoid damage to the roller and bearing. When adjusting the roller distance, attention should be paid to prevent abrasion of the roller surface due to collision between the two rollers.

5. In the mixing process, the glue should be cut first, and then the hand should take the glue. The film is not cut (cut), and the hard pull can not be pulled.

6. the cutter should be placed in a safe place, cutting the rubber should be in the lower part of the roller feed, cutting edge can not be against their own body direction.

7. When debris is found in the rubber material or between the rollers, and there is adhesive accumulation at the baffle plate, the roller should be stopped for processing. It is strictly prohibited to transfer objects above the running roller.

8. In the process of use, mixing tools, sundry can not be placed on the machine, in order to avoid tools falling into the machine to damage the machine.

9. When braking or sudden power failure occurs, the material in the roll seam should be taken out. It is strictly prohibited to start with load.

10.It is strictly prohibited to overload the machine for a long time or use in the case of failure of the safety protection device.

11. After the work is finished, clean up the equipment and spray anti-rust oil to increase the service life of the equipment, cut off the power supply, close the water and steam valves to prevent fire
