Properties of Samples from Polymer Materials Manufactured by the Additive Method V.T.
According to the technology of manufacturing products from polymeric materials, there are materials obtained by the method of casting, centrifugation, pressing, vibrocompression, as well as materials manufactured using frame technology [5–7].
In recent years, the efforts of researchers have been directed towards the creation of materials on additive technologies.
The physical, mechanical and operational properties of the same materials from different manufacturers may differ.

Micromechanics aim at determining macroscopic material properties of functionally graded materials from microstructures and the macroscopic material properties of materials that consist of them.
Due to functionally graded materials behaving mechanically different to both homogeneous and laminated materials, Applying traditional micromechanics to predicting material properties of functionally graded materials have no strict theoretical foundation, which is most likely to lead to large errors.

Preparation System Design of Filling Material with Coal Gangue as Coarse Aggregate Youxia Sun1, a, Dawei Ren2,b 1Key Laboratory of Mining Disaster Prevention and Control of Education Ministry, Shandong University of Science and Technology, Qingdao, Shandong, 266510, China 2College of Natural Resources and Environmental Engineering, Shandong University of Science and Technology, Qingdao, Shandong, 266510, China asyxljl@sohu.com, bdawei_ren_2000@163.com Keywords: coal gangue, green mining, preparation system, filling material Abstract.
Thus far there are mainly four kinds of filling materials, which are high water materials, solid materials, paste filling materials and paste-like filling materials.
However, the preparation systems of the three filling materials are located on the ground, which must cause the secondary pollution by coal gangue processing and increase the transport cost by lifting the coal gangue out of the shaft and carrying the filling materials to underground.
The performances of the two materials developed meet the requirements of gob-side entry retaining and backfilling.

Meanwhile the explosion suppression effects of absorbing materials were studied tentatively in explosion chamber which can simulate mine gas explosion.
In order to compare the absorption effects of different aqueous materials, the same flow and same spray time should be set in every experiment.
Then methane absorption experiments were carried out using different materials and pure water.

With regard to the patents, it could be observed that some palygorskite-based materials have already been patented.
The results show that palygorskite is an excellent alternative for obtaining materials with photocatalystic activity.
The articles found approach the synthesis of these materials by different ways and with excellent results on the degradation of pollutants.
