Principales aplicaciones<\/h3>\n

Papel y celulosa:<\/strong> Se utiliza en los procesos de cocci\u00f3n de la pasta de papel, deslignificaci\u00f3n y fabricaci\u00f3n de papel.<\/p>\n

Detergentes y jabones:<\/strong> Fundamental para la s\u00edntesis de jab\u00f3n, la producci\u00f3n de detergentes sint\u00e9ticos y el refinado de aceites animales y vegetales.<\/p>\n

Industria textil:<\/strong> Act\u00faa como agente desencolante, agente de lavado y agente de mercerizaci\u00f3n para tejidos de algod\u00f3n.<\/p>\n

S\u00edntesis qu\u00edmica:<\/strong> Produce sustancias qu\u00edmicas org\u00e1nicas (\u00e1cido f\u00f3rmico, fenol) e inorg\u00e1nicas (b\u00f3rax, cianuro de sodio).<\/p>\n

Petr\u00f3leo y metalurgia:<\/strong> Refinan productos petrol\u00edferos, tratan los lodos de perforaci\u00f3n de yacimientos petrol\u00edferos y extraen al\u00famina de la bauxita (proceso Bayer).<\/p>\n

Tratamiento del agua:<\/strong> Ajusta el pH, neutraliza las aguas residuales \u00e1cidas y elimina los metales pesados.<\/p>\n

Sector alimentario:<\/strong> El NaOH de grado alimentario se utiliza para la limpieza de equipos y la regulaci\u00f3n del pH (cumple con las normas de seguridad alimentaria).<\/p>","protected":false},"excerpt":{"rendered":"
