Waste Acrylic PMMA Recycling Machine and MMA Monomer Refining Process

This machine technology is developed by Henan Barui TM Company, according to PMMA depolymerization reaction and MMA monomer extraction technology. We continuously improve the reacting condition and efficiency, avoid to use catalyst for the depolymerization reaction. Under the precise control, it can avoid vice-reaction affect the PMMA recycling result. Besides, the MMA monomer extraction unit adopts multi-stage separation process, which realizes the precise control of MMA quality.

This machine technology is developed by Henan Barui Company, according to PMMA depolymerization reaction and MMA monomer extraction technology. The depolymerization reactor adopts Mid-Frequency Magnetic-Influence Heating Stove, which can improve the reacting condition and efficiency, is more safe and avoid to use depolymerization catalyst. Under the precise control, it can avoid vice-reaction affects the PMMA recycling result. Besides, the MMA monomer extraction unit adopts the latest continuous multi-stage separation process, which realizes the precise control of MMA quality. The purity of MMA can reach more than 96.5% or higher.

Currently, HENAN BARUI acrylic recycling technology and machines have been widely used in big industrial production, like 10 ton-per-day, 20 ton-per-day, 50 ton-per-day production line. Our machines have been sold to many provinces of China, like Jiangxi, Guizhou, Liaoning, Henan, and so on. Welcome to visit us and our machines at any time.

Methyl methacrylate (chemical formula: C5H8O2) is an organic compound, also known as MMA, that is an important chemical raw material to manufacture transparent plastics polymethyl methacrylate, simple as PMMA (chemical formula: -[CH2C(CH3)(COOCH3)]n-), that is a kind of organic glass. Acrylic sheets are the products made of PMMA, that is generated by polymerization of MMA, under the presence of initiators. When manufacturing colorful acrylic sheets, there are paint colorings mixing with PMMA.

How HENAN BARUI TM machines produce MMA from scrap acrylic wastes?

  1. Insides the reactor, depolymerization reaction of scrap acrylic sheets break the molecular bond of PMMA, make PMMA (-[CH2C(CH3)(COOCH3)]n-) become MMA (C5H8O2), under the proper temperature and pressure. Meanwhile, there are some initiators, paint colorings and other impurities mixing with MMA. We call it crude MMA.
  2. To purify the crude MMA, that need separate different components, something lighter and something heavier. Meanwhile, some catalyst may be used according to the characteristics of initiators or paint colorings. To avoid the equipment wearing brings impurities to MMA, all parts of equipment contacting MMA are made of stainless steel.
  3. Finally, the produced purity of finished MMA can reach 92% – 99%. That can be used to produce PMMA sheet, with polymerization of MMA, under the proper condition, temperature, catalyst, initiators, paint colorings and so on.
  4. HENAN BARUI TM depolymerization reactor is semi-continuous rotation type. That can realize automatic discharging of carbon residues. And the service life of the reactor is for 5 years, without any repair. You may choose HENAN BARUI TM multi-stage extraction process for the crude MMA refining unit, so purity of MMA can be more than 96.5%. That is good for producing high quality acrylic products. That regular crude MMA refining process can only produce 92% purity of MMA, and the yield of MMA is lower.
  5. We can also supply you the complete technology and acrylic products production machine to produce acrylic products, with the regenerated MMA, produced by HENAN BARUI TM equipment.

Warm tips:
The common crude MMA refining process can only produce 92% purity of MMA, because that separation function only exists in the first hours. Such equipment is cheaper.
This latest HENAN BARUI TM multi-stage extraction process can produce 96.5% purity of MMA, because the separation function exists from the beginning to the end.
