plate ( DStP ) with the use of vermiculite [102 ].
Vermiculite in quantity 100 ves. h. mixed with 10-25 ves. h. связующего в расче на сухое вещество. Then we put a layer of 8-15 mm with one or two layers. When the two-layer veneer is covered with vermiculite cover, a fire-resistant layer is applied to the floor to form a scraper . The cover formed a common coating and applied a second flammable layer. Indicated amount of layer mixed with the associated vermiculite corresponds to the amount of pressed surface 2-6 mm. Shaped envelope, consisting of vermiculite and wood scraper, containing bonds based on urine -formaldehyde resin, pressed at a temperature of 140 - 180 ° C, distances - 0.49-2.9 MPa in the current [94.
It has been established that the size of the vermiculite particle affects the refractory properties of the coating. As we increase their size, we need to increase the amount of vermiculite that burns the vermiculite. When using mixtures of fraction vermiculite, the optimal flow rate is 1 kg per 1 m2 of permeable strength [94].
Vermiculite is a mineral mineral from the group of hydroslides, rising at a temperature of 400-1000 ° C with an increase in thickness of 7 and more. The deposited mass of total vermiculite is 100-200 kg / m3. The material exudes high thermal and sound insulation properties, is non-toxic, non-volatile rot and spreads around the cracks. Unique technical characteristics - temperature, flammability, reflective ability, chemical inertness . Vermiculite является ecologically clean and biostable product . At high temperatures, when driving in fires, no gases are released, which is an important reversal in comparison with other known organic materials
происхождения. This complex of properties is explained by the wide use of vermiculite in different reflection processes.
Vermiculite concentrate is produced from complex vermiculite ore . The ore is subsequently extracted from the ore, then, in a fractional classification, fractionated concentrates. The technology of semiconductor vermiculite concentrate includes gravitational methods of enrichment, as well as the method of air separation. Vermiculite concentrate is a particle of vermiculite particles, it acts as a paste, zernist , porous, with an extremely strong material. When heated, it takes the form of low-lying pillars. Basic vermiculite concentrate is added to the products for the production of vermiculite .
Exhausted vermiculite is made of a smooth, light, high-viscosity material, with a characteristic comb-shaped structure without light. Vermiculite in volatile constituents after the application of hydrated water, has an inclination of 80 to 150 kg / m3 and has a beautiful base for the formation of materials different from it.
In the present time, a certain large amount of refractory coatings, pre-designated for metal, wood, brick, concrete, plastic constructions, and including conclusions were formed .
Particularly effective fire-retardant material is used in the construction-detachment unit (sheets) on the basis of vermiculite and inorganic alloy. Plate vermiculite inorganic refractory - это ecologically pure material, which simultaneously with high refractoriness comprises in itself high indicators of sound-absorption, with a magnificent effect The unit is made up of a series of non-slip sheets, not containing asbestos, wool and organic components. Tiles
chemically neutral, inert, do not contain cellular impurities, non-toxic, biostatic , do not exhibit irritating effects on the skin. In normal operating conditions (from -50 to 50 ° C) and in conditions of high temperatures (up to 1200 ° C), no toxic toxicity is present, dangerous for human health and environment [10].
Vermiculite material is easily processed by standard woodworking instruments and quickly mounted on standard mounting elements or high temperature ABK terminals. Tiles of vermiculite are used in inorganic material and are compatible with the need for fire safety, which gives the opportunity to use them in construction, where the presence of the need for the above will be significantly reduced. Vermiculite sheets are produced in different conditions by the method of high-pressure semi-dry masses [104].
retardant DVP by using the vermiculite concentrate or the whole vermiculite. In our view, this creation is a perspective with points of light lowering the fire hazards of the ancient plateau. As the wound is softened, the fractional composition of vermiculite indicates the influence of the flammable properties of DSPP [ 2, 102]. In connection with this it was faithfully suggested, that in the case of DVP from ancient Greek compositions with the addition of vermiculite, it is necessary to reach a certain size of a particle of mineral, and also to develop a special degree of elaboration.
1.3. Выводы. Formation goals and task research
An important task in light industry today is a complex and rational use of ready-made and re-workable
древесины. In connection with this, all the more attention is paid to the increase in the rate of development of the production of shallow materials, which in the last year are intensively developed with the aim of re-processing the results of lightening and low-intensity. Involvement of various wood-bearing outputs in the production of wood-burning plinth (DVP) enables rational use of wood-burning surface.
In connection with the age of the consonant of the ancient volcanic plates, there is a growing demand and physical and mechanical indicators, which determine the further possibilities and the use of different methods. Обто обстоятельство, безсномнен, требует проведения научных исследований в этом равивлении для полученя высококачественной продукции.
During the preparation of wood-based plots, based on the basic processes, determining the quality of finished products, the process of preparation of wood-based semi-finished products begins, which is a problem for a large-scale production of a large product.
In the result analysis of scientific and technical literature, a single case of application of vermiculite in shallow production with the aim of reducing the fire hazards of finished products - wood-burning boards [102] was revealed. While in the production of DSTP the basic role in the formation of the fabric plays an important role, in the time of production DVP is more important than the process of preparation of semi-finished products, the quality and degree of dependence depends on the process and the process ready plates [105]. Introduction to the ancient composition of mineral gains can withdraw for some room some physical-mechanical properties of finished productions, which will not be allowed. In connection with this it is necessary to follow the process of preparation of vermiculite for the subsequent use of it in the production of ancient veneer plates, and on the basis of these researched institutions.
able preparations vspuchennogo vermiculite. The current ability to allow such a fractional composition of minerals to occur, under which parameters fire hazards DVP will be significantly reduced, and the physical-mechanical properties of the plate will be reduced GOST 4598-86.
In connection with this obvious actuality of the present findings, the elaborate elaboration of rational technological schemes of thought and increased productivity is present in the production of DVP with a significant increase in production.
Highly defined goals and tasks given work.
Aim of the work: To work out the scientific basis of semi-construction and preparation of wood-burning materials in the production of wood-burning boards with reduced fire hazard.
Tasks to follow:
1. Examine the influence of fractional composition and mass valleys on the exposed vermiculite in the ancient volcanic compositions on the parameters of fire hazards ready productions.
2. Determine the parameters of fire hazards of the ancient fibrous plate with the ability to produce with the addition of all the vermiculite.
3. Study the influence of the parameters of the volumetric semi-factory of physical-mechanical properties DVP humiliated fire hazards.
4. Establish basic regularities in the production process DVP humiliated fire hazards wet solution.
5. Develop a composition of wood-burning compositions for halving the wood-burning plate with a humiliated fire hazard wet solution.
6. Propose the technology of production of wood-burning plates humiliated fire hazards wet solution.
2. The program of experimental studies
2.1. Theoretical observations of the structure of education DVP
Properties of the wood-burning plateau, the conditioned capillary-porous structure of the old wood, the chemical composition of the wood-growing materials, the natural connection and the dependence on the technologies used in the wood-cutting process. The basic components of the ancient wolf participate in education DVP, complete with all its functions. If cellulose is a reinforced component and depolymerization and destruction should be limited to the designated parameters of the DVP, then lignin and hemicellulose form a polymer matrix. Exceptions from their compositions lead to lower quality plates [106].
В works N.G. Pure [106] was a representative conditional structural structure of the plates, according to which the plate consists of reinforced microstructures of the wall, forming a spacious set, which is filled with irregularly composed, unobtrusively complex . Armor wolves have different shapes in sections (round, elliptical and ribbon-shaped) and significant dispersion along the valley.
According to the given theories [106] , the involuntary components show the influence of the degree of interconnectedness and the clarity of interconnected connections. Non -volcanic components, coming in the form of plates, according to their ability to educate adhesion bonds can be divided into passive (supplements) and active (binding). Part of the passive non- volatile components, falling between the reinforced volatile components, cause their closeness in the process of complete formation and do not form adhesion bonds with the volatile. Therefore, to a considerable degree, they show the influence of the magnificent relative strengths of the reinforced steel structure. Active neoloknist components and melkodispersion fraction woloka form adhesion and cohesion bonds with reinforcements
In the structure of wolves, they only magnify the related superiority of wolves. In the result, the additional conjunctions «volokno-svuzuzhee - volokno», «volokno - melkodispersna frazi volokna - volokno» are formed.
Поскольку в предложенной модели структуры плиты межволоконные контакты имеют связи адгезионного и когезионного характера, то определяющие их параметры: удельная прочность и энергия разрушения межволоконных контактов, будут зависеть от количества и свойств введенных неволокнистых компонентов и мелковолокнистой фракции.
The milk fraction, in the process of heat or chemical processing, exudes higher hydrophilicity. In the process of forming, they are quick and filling, as high molecular weight, they adsorb water and enter the quality of plastic plastic frames, pre-opening the cracked connection between them.
Under the influence of traffic jams and pressures, the adjusting stress results in a close connection between the fibula and the fibril, and between the closely disposed structural elements - a list of blockages of the joint is formed. The structural structure is fully fixed for the acquisition of cellulose and other polymer components of the tissue- forming compound ( gemicellulose , lignin), which, when pressed, produce an analogous physiological analogy.
Вспученный вермикулит - минерал, который предлагается вводить в структуру древесноволокнистой плиты с целью снижения ее пожарной опасности является, естественно, неволокнистым компонентом, а следуя предложенной классификации, частицы вспученного вермикулита можно отнести к пассивным неволокнистым компонентам, которые оказывают значительное влияние на образование связей в плите, and, consequently, to the physical-mechanical properties of the plates. In connection with this, it is possible to suggest that the mass of ancient wood-burning masses with a reduced fire hazard should be characterized by a long-lasting disease.
The wolves, as determined by a certain amount of small fractions, exacerbate the increase of the indicator of all the squares, on which the connection is established, a particle of mineral is replaced. Thus, it is obvious that the scale of the particle introduction of an inanimate component will show a certain influence on the properties of finished productions. On the other hand, the presented theoretical propositions must necessarily confirm the experimental path. To do this, you need to conduct planning experiments, select basic characteristic models, develop mathematical models with normalized significant factors.
2.2. Choice of basic compositions and methods of examination
The construction of mathematical models of the object is considered an important part of scientific research. All of our experimental observations are based on empirical mathematical models, descriptive and observable objects, that is, the dependence depends on which of the following is a valid statement. The elaborated mathematical models of the object are evaluated by a good instrument. With their help it is possible to determine the interesting characteristics of the object, the results of its influence on one or other factors, the optimal operating modes and the ability to manage the object.
An important stage of experimental observations is the planning of the experiment.
Planning Experiment - This is the formation and realization of an ophthalmic wound on a composite frame, comparing some optimum optimal properties.
In this case, the minimum amount of money must be paid; Simultaneous variation of all factors, determining the flow of the process, by special algorithms, regular processing and interpretation of the results of the experiment [107].
Thus education, in order to solve the set task, the methods of mathematical planning were used in order to solve the process of mathematical description of the mass at the time of preparation.
Matching mathematical descriptions can be half-finished methods: analytical; Experimental; Experimental-analytical. Experimental method was used in the present study. More and more, namely, experimental methods for the study of mathematical models are applied to complex multifactorial processes, which are theoretically poorly studied. Mathematical dependencies, half-hearted methods, do not reflect the physical essence of the object, only the quantitative correlations between the necessary and necessary factors can be established. This is also the first case of small-scale process studies [108].
Experimental methods, based on the processing of data, collected directly on the objects of observation, effective in cases when the laws studied in the object are incompletely informed and lack of information. Experimental methods are divided into active and passive.
Halfway through the passive Experiment equation regressions justifiably only in the volume range of the change of the input parameters, as it existed during the experiment. Active experiment, during which the object is applied to the experienced experiences and studies reactions to these events, are observed, in our eyes are painfully acceptable. Air conditioning is carried out on the object in conjunction with some optimal plan, allowing the necessary effects to be provided quickly, as well as building models, with adequate results of the experiment. Semi-finished results of experimental results allow half the regressions to be obtained, which should reflect a small quantitative correlation.
Between incoming and outgoing magnitudes, and not physical inclination, as has already been shown, the outcome of the study process. Ути уравнения справедливы только для того диапазона изменений входных величин, который имет место при Становновке опыта, и разспространять результаты пексперимента на боело жирокий диапазон как недом припустэ доэстиствен
In comparison with the traditional method, mathematical plans of the experiment significantly hide the necessary number of objects and evenly investigate the factor space. But they can be used only under conditions of normal law distribution of output parameters. In the present case, the condition can be accepted without additional checks for the reason that the quality indicators of the DVP determine the action of the greater number of factors, since the analysis of the literary data does not follow from us. Therefore, according to the central theory of probabilities under lobby laws, the distribution of incoming factors, the incoming parameters will be distributed according to the normal law [109, 110].
In the production of DVP there is a place for simultaneous flow of chemical, thermophysical, mechanical and other processes, which are very important in terms of composition and properties of the medium - wood, mixed with chemicals. It divides perspective perspectives on classical analytical methods by introducing quantitative regularities of processes, the need for optimizations of technological regime and algorithms of process management. In any case, the conducting mechanism of the basic production processes is not possible if there are no visible results in a given course [111].
For the construction of mathematical models, descriptive interests of us processes, and namely the process of learning the ancient wolf from the technological skills in the production of DVP with humiliation
fire hazard was selected active multifactorial experiment.
Planning one-factor experiment. To solve the task of determining the effective parameters of the work performed for the production of wood-bearing masses in the production of wood-bearing plates, it is possible to conduct one-factorial experiments with the experimental model for the semiconductor model.
Method of processing the results of the experiment with the purpose of describing the object - the method of naming squares. An experiment consisting of N units, equating one another with another а shag Ь.
A general equation for one-factor experiment looks at the following education:
