1. Raw materials and methods of consumption

  Consumer synthetic resin comes from abundant raw materials. Initially, it was dominated by coal tar commodities and calcium carbide calcium carbide, and now it is mainly dominated by crude oil and natural gas commodities, such as ethylene, propylene, benzene, indoor formaldehyde and urea solution. The consumption method of synthetic resin is selected from polymer, floating polymer, emulsion polymerization, solution polymerization, melting polymer and interfacial polycondensation.

       2. Synthetic resin

  Synthetic resins are high-molecular compounds, which are consumed by raw materials with low molecular structure-monomers (such as ethylene, propylene, vinyl chloride, etc.) that have been separated into biomacromolecules by strong reaction of polymers. Common polymer methods in industrial production include 4 types of polymer, floating polymer, emulsion polymerization and solution polymerization.
  

       3, the polymer method itself

   The polymer itself is the whole process of monomer termination under the effect of initiator or heat, light and radiation source without other medium. The product is characterized by childlike innocence, without complicated separation and purification, the actual operation is relatively simple, and the utilization rate of consumer machinery and equipment is high. Can immediately consume quality products such as pipe fittings and plates, so it is also called small polymer. The disadvantage is that the viscosity of the raw material is often increased with the termination of the polymerization and the strong response, the mixing and heat conduction are difficult, and the temperature of the strong echo is not easy to control. The polymer method itself is commonly used in the consumption of resins such as polymethylmethacrylate (alias Plexiglas), polyethylene, low density polyethylene, polypropylene, polyester, and polyacryl.

    4. Floating polymer method

  Floating polymer refers to the whole process of the polymer that the monomer is dispersed into liquid under the effect of mechanical equipment mixing or shaking and dispersing agent, generally floating in water, so it is also called bead polymer. The characteristics are: there is a lot of water in the strong reverberator, the viscosity of the raw material is low, and it is very easy to conduct heat and manipulate; after the polymer, it only needs to go through a simple process of separation, washing, boring, etc., to obtain the epoxy resin product, which can be used immediately Forming production and processing; the commodity is more innocent and average. The disadvantage is that the consumption of strong echoes can not be as good as the purity of the commodity itself, and the continuous method cannot be used to terminate the consumption. Floating polymers are widely used in industrial production. 75% of the polyvinyl chloride epoxy resin uses the floating polymer method, and polyethylene is also the key to the floating polymer method for consumption. The strong reverberator is also gradually becoming larger.
  

      5. Emulsion polymerization

Emulsion polymerization refers to a polymer that, depending on the action of an emulsifier, is mixed with mechanical equipment or shaken, and the monomers form a moisturizing emulsion in water to terminate. The emulsion polymerization strongly reacts with latex, which can be used immediately or damaged. After washing, dullness and other post-treatment processes, powdery or fibrous polymers are obtained. Emulsion polymerization can obtain a higher content of polymer at a higher rate of strong response. The viscosity of the raw material is low, which is convenient for heat conduction and mixing, consumption is very easy to handle, and residual monomers are very easy to remove. The disadvantage of emulsion polymerization is that the thickeners that are registered during the whole process of the polymer harm the characteristics of handicrafts. In order to obtain liquid polymer, the loss goes through the whole process of cohesion, separation, washing and other processing techniques. The consumption of strong echoes can be lower than the polymer method itself.


       6. Solution polymerization

  Solution polymerization is a strong reaction of the polymer terminated by the monomer dissolved in an appropriate organic solvent. The polymer composed sometimes dissolves organic solvents and is classified as a typical solution polymerization. The commodity can be used as architectural coatings or adhesives. If the polymer does not dissolve the organic solvent, it is called precipitation polymerization or slurry polymer. For example, the consumption of liquid polymer must be settled, filtered, washed, and dull before it becomes waste. In solution polymerization, the actual consumption and strong reaction temperature are easy to control, but all require the acquisition of organic solvents. Continuous polymerization and intermittent methods can be used for solution polymerization in industrial production, and continuous methods are often used for large-scale consumption, such as polypropylene.
