Consumer properties, which should be taken into consideration: 1) The unique toughness of the material (the highest rate of all known polymers), namely, Over 160 kJ/m2 2) High abrasion resistance 3) Low friction coefficient (self-lubricating) 4) High resistance to chemically aggressive reagents (media) 5) High creep resistance (geometric stability) Ordinary way - This type of process is quite expensive. Production of PE125, in compounding with bimodal PE100, from 8 to 45% of supermolecular polyethylene is injected, reaching dispersion by multiple compounding (4 stages) in an extruder cascade (XXXXX technology). GRAFTALEN™ MP-UHHD (alloy) is a MELT-PROCESSABLE concentrate of UHMWPE on an HDPE matrix. As HDPE, you can choose the most affordable HDPE (pipe) grade. To obtain polyethylene according to the standards PE125 (with a minimum strength indicator MRS> 13.8-14 MPa, in comparison PE100 has MRS only 10 MPa), a significant improvement in the resistance against hydrostatic pressure is required. For a conventional bimodal HDPE, this indicator is difficult to achieve, since it directly correlates with the impact strength/density indicators and with simple extrapolation, it turns out that the required indicator for PE125 simply does not reach the bimodal HDPE matrix. Another problem - the difficulty in maintaining the geometric stability of the pipe (the thickness at the top of the pipe is often less than at the bottom) due to the sagging effect (the phenomenon of the gravitational flow of a polymer melt). This phenomenon is more pronounced for thick-walled pipes. The specific blend of HDPE with UHMWPE allows solving these problems above.

UNIVERSIDAD DE ALICANTE posted this:Production of briquettes for energy recovery of furniture waste with polyurethane foamsThe Research Group "Waste, energy, environment and nanotechnology" (WEEN) from the University of Alicante has developed a new compact material and a production process of briquettes of furniture waste. This process makes it possible to carry out the management and the energy recovery of this waste, avoiding the environmental problems associated with its landfilling and also making it easier to transport, handle and store. The briquettes obtained, show physicochemical characteristics similar to the conventional and they have a high energy density being able to be used as fuel for thermal power plants or industrial boilers. Companies in the waste treatment sector and the furniture industry that are interested in commercial exploitation of this technology through licensing agreements and / or technical cooperation are sought.

The proposed dynamic solidification model allows for real-time simulations of heat transfer and solidification of continuously cast steel slabs and billets. The model can also be coupled with optimization modules for the effective and appropriate control and regulation of casting.

The zeolite is partially interchanged with cations of one or several non-noble metals. In order to achieve an optimum performance of the catalytic trap, these metals should be interchanged in the internal zeolite structure, and never on its external surface. In this way, the outflow of the exhaust gases passes through the catalytic trap bed to adsorb the HC at low temperatures. The material has been developed at laboratory scale. Different compositions of this material have been tested with simulated streams of internal combustion engines (cold starts). As a result, the material is able to reduce HC emissions in internal combustion engines operating with both mixtures almost stoichiometric and low fuel mixtures. The main difference between this invention and other existing materials is that this catalytic trap avoids any element or additional layer composed of an oxidation catalyst based on noble metals. Consequently, HC emissions could be totally removed through a single bed without using high-cost materials (noble metals) or further stream treatments. This fact allows the catalytic trap to be placed in any position according to the different control systems employed for decreasing other pollutant emissions existing in the gases stream, since the total elimination of HC takes place on the catalytic trap. Thus, this technology development results in a solid material where coexists metal(s) and protons in an optimum ratio inside of the zeolite channels, leading to a system that can act as a HC trap and as an oxidation catalyst in only a single bed, during the whole cold start cycle. The main innovative aspect of this catalytic trap is that the adsorbent material can capture the hydrocarbons in the cold start of the engine and oxidize gases during its warmed-up operating conditions without using noble metals, which are frequently used as oxidation catalyst. At high temperatures, this material is able to carry out total oxidation of both hydrocarbons retained by the catalytic trap and those present in the exhaust gas stream. Consequently, the resulting gas stream released to the atmosphere is innocuous in hydrocarbons. • Noble metals are not used. • Structural advantages, since the control systems are simplified and pollutants in internal combustion engines are reduced. • Economic benefits (The price of noble metal is approximately 100 times more expensive than the materials employed by the researchers). • The catalytic trap can be placed in any position with regard to different control systems. • Besides its hydrocarbon trapping role, the system can also act as oxidation catalyst during the cold-start cycle.

The development of a universal and inexpensive method of water purification is very difficult, because it may contain pollutants of different nature, e.g. heavy metals, organic compounds (pesticides, chlorinated aromatic compounds, antibiotics and surfactants) as well as bacteria. The water purification methods currently in use are based on osmosis, ion-exchange, adsorption, ultrafiltration, distillation and photooxidation. Although multifarious, they have limitations, mainly connected with their high power consumption and low efficiency.
