Introduction
The problem of getting biocide materials that are not affected by different molds and
microorganisms is faced by a number of fields of domestic economy. This includes various kinds
of package materials used in food, medical, cosmetical, electro-technical, and other industries.
Getting of biocide paper that can stand against bacterias (bacterial), molds (fungicidal), and
insects is the problem the mankind has been tackling for a very long time [1].
Biostability of cellulose fibers is being searched and learnt even nowadays. There are
several ways of solving this problem: mechanical, fungicidal, etc. [2] Biostability of the materials
can be increased by modifying the chemical nature of cellulose. [2] Obviously, it’s easier and less
expensive to use non-organic fibers in compositions, in particular - basaltic. These fibers (of
unlimited fund) are get by stretching under high temperatures with air steam by frictional forces
between it and the fiber, which is moving with variable speed. At the same time, fibers are not
only stretching, but also are separated, divided. Materials that is being created, has durability of
80% of the initial one, in distinguish to other natural fibers that are got by the same technology,
but with 50% of the initial durability.
171
Basaltic fibers are high-temperature resistant materials, with low chemical activity, which
is very important - they do not conduce to spreading of different molds and microorganisms, are
not affected by mildew, bacterias, and other pests, rodents, beetles, mosquitoes, etc.
Experimental part
Getting of carton-like materials basing on basalt fibers (BAS) like tiles, felt, scale, etc is
not a problem. Such materials do not contain binders in their composition content, but have
evenly intertwined basalt fibers. They have low durability, in practice after vacuuming (drying)
they can hardly be taken off the net, as basalt fibers do not have paper-creating properties (not
fibrilized, no hydrogen bonds), inter-fiber relations are purely mechanical. That is why for getting
a more durable thin paper-like material, applying of bonding substances is critical. Keeping this
in mind, depending on the usage conditions and requirements to the ready-to-use product,
different binding materials can be applied. The most popular and handy binding material is
cellulose (if further used under 120-130°С).
Cellulose (CEL) and basalt fibers have electro-kinetic potential which is equal by sign and
opposite by value, and which rise on the boundary of phase separation (solid-fiber-solution).
Reloading of the surface of one of the contacting fiber is learnt to give a possibility to get a
composition material that consists of oppositely charged particles (reloading of the surface of
cellulose fibers goes under
pH=3.7-3.8, but basalt fiber is recharged under pH=4.9-5.1), material durability and its
biostability is significantly increased [3] Thus, for example, durability of materials with 20-25%
of basalt fiber in composition with cellulose ones during recharge of the cellulose part of fibers is
increased more than 24%.
Recharge of cellulose fibers is possible without separation of fiber, using sulfate of
aluminium and without changing the potential of basalt fibers (without separating the
components). Consequently, mutual coagulation of oppositely charged fibers is increased,
properties of materials are improved [4].
Researches performed earlier confirmed that in order to get thin, flexible, and heat-
resistant material, which stops distribution and development of microorganisms, argillaceous
minerals can applied [5]. Bentonite clays are known to be associates of clay minerals with
prevalence of montmorillonite (MOT) in them. Mineral content of such clays is high-disperse
formations that mainly consist of fractions of less than 0,001mm.
Affected by water, montmorillonite transfers from elastically brittle condition to the
flexible condition because of bound and capillary water. Contact of clays and water provokes an
active swelling process. For the sake of research, rock-forming fraction of bentonite clay is
selected by soaking in distilled water and pouring out of the top 10sm layer after 24-hour settling.
Pyzhev bentonite of Chercassy deposit was applied in the procedure, as it contains sodium
oxide due to which it becomes more active because of intensive hydration and increased stability
of the system.
There was a research on possibility of getting and appliance of thin paper-like material
based on basalt fiber in compositions with recharged cellulose sulphite fiber (SFI) and its ether
(carboximetilcellulose, KMC). Compositions were injected with montmorillonite, a clay mineral.
Sorbic acid was used as a fungicidal-active material, which was applied from water suspension
with binding material of carboximetilcellulose. Because sorbic acid contains rough disperse
particles (up to 100mkm), to increase sedimentary stability, it was additionally fragmented in the
ball mill to get particles of a middle size (15-20mkm). This was done to ensure qualitative
coverage and significant fungicidal properties of the material [6].
172
The obtained material was processed by 5%-solution of carboxymethylcellulose.
Bactericide activity was researched regarding to pathogenic microorganisms: Staph.aureus and
F.coli. Derivatives of nitrofuran and triazine series (furalhyn, hexacid, ethonium, vazin – they
depress growth of pathogen bacteria) were used as bactericide reagents.
Results of the researches of antibacterial properties of the materials are represented in
Table 1.
From Table 1, it’s obvious that the best variant of the composition, which effectively
depresses growth of microorganisms, contains basalt (50%) and cellulose (50%) fibers, sorbic
acid (50%) and hexacid, 15% of montmorillonite, a bacterial reagent. Obtained modified
materials that are part of basalt and cellulose fibers, and up to 15% of bentonite clay
montmorillonite, were tested against durability and filtering ability in accordance with the
methodics [4].
It is proved that a characteristic feature of clay suspensions is their low stability associated
with the extremely developed phase interface by the presence of an excess of surface energy that
facilitates the aggregation of the particles of the dispersed phase and the coagulation of the
system.
Improving the properties of clay suspensions can make them more stable by treating them
with surface active water soluble substances of synthetic or natural type. The main one is to
increase or develop the swelling process, which is due to the peculiarities of the wall structure of
the montmorillonite lattice. The result of the manifestation are hydrophilic properties of the
system [7]. The use of surface active substances helps to change the molecular nature of the
surface and makes it possible to obtain systems with a new features.

The effect of polar organic compounds during their exchange adsorption on the surface of
clay particles was studied. The behavior of sodium humates of carbonate alkaline reagents (SH)
and sodium salts of resin acids of SSRA in relation to a representative of bentonite clays,
montmorillonite.
Suspensions of Piezhevsky montmorillonite treated with alkali-reagent proved that 1%
additive is sufficient for research it. Clay suspension under these conditions has acquired high
stability and thixotropic properties. The system did not change the structural-mechanical type.
There appeared greater rapid elastic deformations, which can be explained by the presence of
developed protective shells around solid particles of dispersed phase.
The treatment of montmorillonite particles with sodium salts of resin acids of SSRA
showed that 4% of solutions for this purpose are sufficient to obtain a strong and stable
suspension in which conditions are created for the formation of coagulation structures.
Significant changes in the surface properties of bentonite clays are achieved by the exchange
adsorption of polar organic compounds. In this case, the surface of clay particles is completely or
partially a screened polar functional group.
Table 2 demonstrates that appliance of clay minerals with high ion-exchange capacity
leads to peptization of particles, their stabilization, and increase of forming the structure. This
reflects on basic durability characteristics of the materials. Thus, decrease of binding material in
the composition does not mitigate the main parameters of durability and filtering capacity.
Basalt fibers are known [1] to be the great protection from external impact of different
fungus, microorganisms, so the authors suggested applying them in compositions for producing
package materials (specifically for food designated for long-term storing). The pH level of
environment is known to significantly influence the degree of infecting of plant fibers by molds.

and growth of cellulose are mainly created in acid environment, and only Stachybotrus atra’s
optimal value is deviated to alkalinity - pH=7,5. It’s interesting that increasing of alkalinity, say
up to 8, and its decreasing down to 5,5 - this fungus stops producing cellulose. This can be the
reason why the degree of coverage by this fungus is less than by fungus of other kinds. In
general, our investigations were held in acid environment (pH~4,9-5,2).
The easiest method of research of biostability is the visual one, which involves wetting
samples, infecting them with fungus of a particular kind, and placing them in a dark place [8].
The main requirement as for the research methods was that the investigations should have been
held in tough conditions for materials and favorable conditions for development of
microorganisms.
To be the most objective, stability of the materials against the fungus was tested with
three methodics: in liquid environment of Van-Iterson, on the surface of non-alkali ahar
(environment of Chapek) and in wet cell with relative humidity of 98%. Seeding was estimated
by 10-degree system, where 10 is the highest degree of overgrowth. The results of the
investigation of materials destroy under impact of fungus are represented in Table 3.

Only specific and equal in all cases qualities of the nutrient medium were considered.
Seeding was performed with equal amount of homogeneous water suspension of spores. From
Table 3, it’s obvious that there is no material that could stand against fungus infection, but
infecting has different degree.
To unify tests of different compositional materials against biodurability, international
electro-technical committee suggested a set of fungus, which will be the indicator of biodurability
of the materials. Among them, there are three main “cellulose destroyers” (Stachybotrus atra,
Chacktomium glohosum, Paecilomyces variety). All the biostability tests are held under the
toughest conditions created for the material under investigation, but the most favorable for
development of microorganisms. The methodology of identification is described in [4]. To be
more objective. samples of materials were tested by three methods: in the liquid environment of
Van-Interson, on the surface of non-alkali ahar (Chapek’s environment), and in wet cell with the
relative humidity of 98%. Seeding was held weekly during 180 days. Results are represented in
the Table 3.
Tests were conducted with “clear” and “infected” fungus, meaning selected from the
infected paper.
Method of carrying out the tests consisted of two parts of visual observations and
qualitative characteristics. Qualitative analysis of the destroyed paper was help in the following
way: a sample of the paper without infection with fungus and in a month after infecting were
dried till the constant weight and weighted. The difference in the weight gave the quality of the
destroyed material.
These samples were tested against biostability in relation to some “active” fungus and
microorganisms and microelements. Methodology of tests is described in the [5]. Covering by the
fungus was estimation by 10-degree scale. Maximal coverage was equal the minimal stability
against the fungus.
Conclusions:
1. Almost all materials under investigation more or less were affected and destroyed by
fungus.
2. Materials that contain more cellulose are affected by fungus more and faster. Samples
which content of cellulose is up to 85% are affected by 5-6 day, in 12-15 days the
material is totally covered with fungus. The materials that contain up to 20% of cellulose
fiber are more stable: fungus appears only in 15-17 days.
3. Increase of basalt fiber in the composition content lead to increase biostability of the
materials.
4. Biostability materials and their strength characteristics have been significantly improved
by introducing bentonite clay - montmorillonite into the composition with the surface
treatment with organic compounds such as sodium humate (SH) and sodium salts of resin
acids (SSRA).
5. That’s it: pathogenic microorganizms such as Staph. Aureus type and depressed F.coli
are proved to be depressed in the best way by the composition of 50% basalt + 50% KMC
+ 50% MOT + hexacid + sorbic acid.
6. The best indicators are got by materials that contain bentonite clay of the montmorillonite
kind and little quantity if cellulose fibers (30%).

Coli, and derivatives of nitrofuran range are used as bactericide reagents. Appliance of clay minerals of the montmorillonite type in the composition with basalt fibers is proved to get materials that are characterized with high biocide properties and excellent service characteristics. Thus, appliance of basalt fibers in this direction has a very positive perspective. This paper describes a methodology of producing a strong thin paper-like biocide material based on non-organic basalt fibers, which can be used in many industries of domestic economy. Материалы, в составе которых содержатся наиболее распространенные в природе углеводы - целлюлозные волокна, подвергаются воздействию различных плесневых грибов и микроорганизмов известно давно. 700 бактерий актиномицетов и грибов используют целлюлозу как источник углерода. Эти микроорганизмы содержат специфический фермент - целлюлаза, отвечающий за разрушения целлюлозы. Проблема получения биоцидных материалов, не подвергающихся влиянию разного рода плесневых грибов и микроорганизмов беспокоит многие направления и отраслей промышленного производства. Например, различного типа упаковочные материалы, используемые в пищевой, медицинской, косметической, электротехнической и других направлениях промышленного производства. В работе продемонстрированы некоторые возможности получения биоцидных материалов на основе базальтовых волокон с использованием целлюлозы и ее эфиров, обработанные растворами бактерицидных препаратов - производных нитрофуранового ряда и определяют бактерицидную активность по отношению к болезнетворным организмам: стафилококка золотистого (Staph. Aureus), кишечной палочки (F . Coli). Доказано, что использование в композиции с базальтовыми волокнами глинистых минералов типа монтмориллонита позволяет получить материалы, характеризующиеся высокими биоцидными свойствами и хорошими служебными характеристиками. Таким образом, использование базальтовых волокон в данном направлении - очень перспективно. Про те, що матеріали, у складі яких містяться найбільш розповсюджені у природі вуглеводи - целюлозні волокна, піддаються впливу різноманітних плісньових грибів та мікроорганізмів відомо давно. 700 бактерій актиноміцетів та грибів використовують целюлозу як джерело вуглецю. Ці мікроорганізми містять специфічний фермент – целюлазу, що відповідає за руйнування целюлози. Проблема одержання біоцидних матеріалів, що не підпадають під вплив різного роду плісньових грибів та мікроорганізмів турбує багато напрямків та галузей промислового виробництва. Наприклад, різного типу пакувальні матеріали, що використовуються в харчовій, медичній, косметичній, електротехнічній та інших напрямках промислового виробництва. У роботі продемонстровано деякі можливості одержання біоцидних матеріалів на основі базальтових волокон з використанням целюлози та її ефірів, що оброблені розчинами бактерицидних препаратів - похідними нітрофуранового ряду та визначають бактерицидну активність по відношенню до хвороботворних організмів: стафілококу золотистому (Staph. Aureus), кишківної палочки ( F. Coli). Досліджено, що використання у композиції з базальтовими волокнами глинистих мінералів типу монтморилонітів дозволяє одержати матеріали, що характеризуються високими біоцидними властивостями та хорошими службовими характеристиками. Таким чином, використання базальтових волокон у даному напрямку – дуже перспективно.
