Project summaryDevelopment of the chemical industry has led to occurrence of numerous plastics. One of the most widespread is PET – polyethylene terephtalate. PET has found application in many branches, including in packing products and drinks, for example, plastic bottles. It is a cheap, hygienic, technological material. However its wide application has led to occurrence of problems of recycling waste products (used production). This problem is extremely sharp especially for big cities.
The project is directed on development of new ways of recycling PET. As PET is chemically proof material and in usual conditions does not decay, it was offered to develop new building materials on its basis. Distinctive feature of these ways is application of special antiseptic agents. Building materials have porosity. At contact of such material to the natural environment, microorganisms that have an adverse effect on safety of presence of the person in such rooms start to accumulate in these pores. Usual way of protection from microorganisms is the covering of building designs with antiseptic agent or waterproofing. However the covering in due course can be damaged, that will lead to penetration of microorganisms inside of a building material.
In the project it is offered to enter antiseptics into a mix of components during manufacturing the material. It will enable to avoid danger of a congestion of microorganisms in building designs. For this purpose it will be developed special antiseptics, which does not decay at temperatures of reception of a composite material on the basis of secondary PET.
The base circuit of reception of new building materials on basis PET is the following:
1. Preparation of PET
2. Preparation of filling material. Sand, gravel, beaten brick, rubber crumb, ashes, sawdust, etc. can serve as such material.
3. Mixing components
4. Addition antiseptics
5. Heating with hashing
6. Forming building products from the received mix on presses
7. Extraction of products from forms and finishing processing
Researches will include definition of rational structure of the materials, the rational sizes of particles of filling material, the rational size of initial particles of PET, definition of temperature modes of hashing and processing on presses, rational volume of pressings, composition of antiseptics, their rational percentage, methods of entering antiseptics, research of mechanical and service properties of a material depending on modes of manufacture, design and shape of the technological tool, definition of energy-power parameters of forming products on presses, definition of rational capacity of presses, etc.
The significant part of the project is devoted to research of coupling of components among themselves as this coupling determines durability of the material. Coupling between components is influenced with numerous factors: temperature of processing, natural properties of filling material and its humidity, dispersiveness of components, ways of entering filling material in a mix, modes of hashing, etc. The modern research equipment will be applied. For research of adhesion between components, including electronic microscopy will be used..
Separate part of the project will be investigation of possibility to use reinforcing elements in such materials. Reinforcing will enable increasing durability of products considerably. But for this purpose it is necessary to determine factors of linear thermal expansion of the developed material and dependence of these factors on the kind of filling material and its percentage.
The most perspective (in our opinion) are the following applications of developed materials: edge stone, pavement plates, tile, trays for drain of sewage, road protections, etc.
The collective of employees includes doctors of sciences, candidates of sciences, post-graduate students and highly skilled workers that gives confidence in successful performance of the project. The project completely meets the requirements of ISTC and is directed on the decision of especially peaceful problems, connected to the decision of essential environmental problems.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
