Good to know
Chlorine is a toxic, corrosive, greenish-yellow gas that is irritating to the eyes and to the respiratory system.
Much chlorine is used to sterilize water and wastes, and the substance is employed either directly or indirectly as a bleaching agent for paper or textiles and as “bleaching powder” (Ca[OCl]2∙CaCl2∙Ca[OH]2∙2H2O).
Kasutatakse pleegitite tootmiseks ja vee kloorimiseks.
In TCF bleaching, the use of chlorine containing bleaching chemicals is completely avoided and thus so are the emissions of organic and organochlorinated substances from bleaching.
