1.Propiedad del producto<\/h4>\n

El sulfito s\u00f3dico es una sustancia inorg\u00e1nica cuya f\u00f3rmula qu\u00edmica es Na2<\/sub>SO3<\/sub>. Es la sal de sulfito de sodio. Se utiliza principalmente como estabilizador para fibras artificiales, agente blanqueador para tejidos, revelador para fotograf\u00eda, desoxidante para te\u00f1ido y blanqueo, agente reductor para fragancias y tintes, y agente degradante de la madera para la fabricaci\u00f3n de papel.<\/p>\n

3.\u00c1mbito de aplicaci\u00f3n y uso<\/h4>\n

Se utiliza principalmente como estabilizador de fibras artificiales, agente blanqueador de tejidos, revelador fotogr\u00e1fico, decolorante blanqueador de tintes, agente aromatizante y reductor de tintes, y agente eliminador de lignina para la fabricaci\u00f3n de papel.<\/p>\n

4.Embalaje y almacenamiento<\/h4>\n

El sulfito s\u00f3dico anhidro se envasa en bolsas de papel kraft recubiertas de pel\u00edcula de PE o en bolsas tejidas de pl\u00e1stico de 25 kg de interior. Para productos de grado alimentario, se requieren medidas de doble capa a prueba de humedad. Debe almacenarse en un almac\u00e9n fresco y seco (<30\u2103), cerrado herm\u00e9ticamente para evitar la humedad y el aire (es propenso a la oxidaci\u00f3n), y mantenerse alejado de \u00e1cidos y oxidantes. Durante el funcionamiento, asegure una buena ventilaci\u00f3n (ya que la descomposici\u00f3n produce SO\u2082). La vida \u00fatil es de 24 meses.<\/p>","protected":false},"excerpt":{"rendered":"
