Researchers began to try to extract the chemical components of the plastic for reuse. The process used is to cut off the long chain of the polymer and restore its original properties. The cracked material can be used to make new plastics. Some methods involve the chemical cracking of the combined carbon atoms by the addition of chemical elements, or the addition of energy to cause their thermal cracking.
Bayer AG has developed a hydrolyzed chemical reduction method to crack PUC sponge mats. Tests have shown that chemical reduction is technically feasible, but it can only be used to treat clean plastics, such as corner powders and other plastic waste produced during manufacturing. Plastics contaminated with other contaminants used in the home are difficult to treat by chemical decomposition. The application of this reduction method will not use the hydrolysis method to treat waste in the 21st century. Some new chemical decomposition methods are still in the process of research, and Ford Motor Company of the United States is currently applying ester hydrolysis to the treatment of automotive waste plastic parts.
The US-based Rendezvous Institute of Technology has developed a solution that decomposes plastic waste, heating this patent-pending solution with six different types of plastics that are mixed together. Six different polymers can be extracted at different temperatures. In the experiment, the polystyrene plastic chips and related solutions were mixed into a dissolved state at room temperature, sent to a sealed container for heating, and then sent to a lower pressure "flash chamber", and the solution evaporates quickly ( Recycling is done again, and the rest is pure polystyrene that can be reused.
It is said that the purification unit used in the study can purify 1 kg of polymer per hour. New York State Government and Niagara. Mohawk Power is planning to team up to build a small pilot plant. Investors claim that after the plant is completed, 4 tons of polymer raw materials can be recovered per hour. Its cost is only 30% of the raw materials produced, and it has very obvious commercial value.
A Torque Sensor is a transducer that converts a torsional mechanical input into an electrical output signal.
Here are 2 types of torque sensors:
a reaction that measures static torque,
and a rotary that measures dynamic torque.
Metal foil Strain Gauges are bonded onto a flexure of a structural member that deforms when a torsional or twisting motion is applied.
In most cases, 4 metal foil strain gauges are used to obtain maximum sensitivity and temperature compensation. 2 of the gauges are usually in tension, and 2 in compression, all 4 strain gauges are wired in a Wheatstone bridge configuration with compensation adjustments that correct for temperature errors.
