Basalt fiber based biocide materials

Abstract

It has long been known that materials containing cellulose fibers in their composition are destroyed by molds, microorganisms, actinomycetes, which use cellulose as a carbon source. Different fibrous materials to varying degrees (but always) are affected by molds. It is known that linseed and cotton types of paper are affected by the smallest number of fungi, and sulphate ones by the largest. The most biostable is cotton paper, the composition of which contains chalk in a sufficiently large amount. The observations carried out by the authors showed that the highest biostability (fungal resistance) is characteristic of papers containing chalk and kaolin, the lowest is glued types of paper with a high degree of sizing. Aging of paper with increasing temperature increases the overall susceptibility of all types of paper tested without exception. Obviously, changes in the physical and chemical properties of paper as a result of aging create more favorable conditions for the growth of fungi. It is well known that paper can serve as a medium for the spread of infectious diseases. The authors of the article studied the thermo-physical properties of basalt fiber and investigated the possibility of using it for the manufacture of heat-insulating technical paper.Obtaining materials that are not affected by bacteria, insects and molds (fungicidal,insecticidal) can be solved by using inorganic fibers, which are obtained from almost unlimited natural resources and which have excellent biochemical properties. It should be noted that the concept of "biocidal" paper (material) is collective. It combines species that differ in their ability to kill bacteria (bactericidal), molds (fungicidal), insects (insecticidal). Each of the biocidal types of materials has two or more of these properties.

Study on the possibilities of effective use of basalt

“…1, a). Shevchenko in his work on the topic "Creation of basalt fiber production technology based on raw material minerals of the Republic of Uzbekistan" [3] showed that concentration intervals based on basalt, limestone, phosphorous components obey the fundamental laws of the formation of difficult-to-dissolve eutectics in silicate systems, the quantitative change of solids when adding additives and found that there is a direct relationship between the viscosity of the solution. In addition, he justified the possibility of using the mineral raw materials of the Republic of Uzbekistan for the industrial production of high-quality basalt fiber.…”
