FIRE PROTECTION OF CELLULOSE-CONTAINING MATERIALS

Abstract

The article covers the issues of fire protection of cellulose-containing materials, in particular wood. It is shown that despite a number of valuable properties that wood possesses, it is a rather combustible material by its composition. It is known from literary sources that one of the most important steps in protecting wood from fire is fire-retardant treatment. It is carried out in two main ways: surface treatment (application of special compounds to the surface of wood to form a fire-resistant layer) and deep impregnation of wood with fire retardants. The purpose of the research is to develop an effective flame retardant on a varnish basis. The authors of the article developed a varnish-based flame retardant consisting of a system of flame retardants (phosphate base combined with dextrin) and functional additives. In the research methodology, it is stated that the testing of wood samples was carried out in accordance with DSTU 8829 on the OTM installation, within 300 seconds for each sample. The methodology also includes means for measuring flue gas temperature, test time, and determining sample weight loss before and after tests.
