Diseño de un reactor para la fabricación de resinas vinílicas utilizadas en la elaboración de colas blancas en la Empresa Pintuglobal del cantón Mocha.

Abstract

The present research deals with the design of a reactor to make vinyl resins used in the production of white glues at the company Pintuglobal, Canton Mocha, Province of Tungurahua, where the inductive method was used to make laboratory determinations obtaining specific parameters required: temperature and concentration, which became the starting point to dimension the reactor, also the experimental method was used to explain how the vinyl resin was obtained. By the Add method, the reagent concentrations of reactives, the actual and theoretical capacity of the reactor and the temperatures suitable for controlling the polymerization reaction were specified; and finally, the time required for the reaction to polymerize. In the function of tests and a test bench, through the simulation process, the experimental data were obtained as: stirring speed of 60rpm, reaction temperature 55 o C, flow of monometer addition, 0,3cm xvi

3 /min, flow of addition of Potassium persulphate 0,2cm 3 /min and the time required for polymerization; total of the monometer 6hs, therefore, it concluded with the validation of the engineering design for the Type Batch reactor by means of laboratory tests, and they were obtained: percentage of solids at 150 o C of 36,80%, viscosity of 37050 cP and a pH Of 4.3; These parameters are within the contemplated in the standard of the company Pintuglobal and based on NTE INEN-ISO 3219 norm. Once the research is started, Pintuglobal is recommended to perform a risk matrix, identifying the manipulation of reagents such as the vinyl acetate monomer (VAM) and Potassium Persulfate.
