The presence of calcium CaOmagnesium MgO abnh potassium K2O assist with increasing resistance to sudden changes in temperature. Such a productive increase demands a large amount of raw material which generates environmental problems related to the scarcity of natural resources.

Lead hazard evaluation for cathode ray tube monitors in Brazil

The monitors were weighed and their parts were separated and sorted into four categories: Chemical and mineralogical characterization tests of the raw materials carried out.

Surface properties of new green building material after TiO2—SiO2 coatings deposition. Study for vitreous waste recovery in the formulation of heavy clay ceramics. Improper WEEE handling and recycling may lead to health problems as these equipment contain harmful substances such as toxic metals and flame retardants Lecler et al.

Journal of Thermal Analysisv. Neck, funnel and panel parts Fig 3. Future studies should evaluate the hazardousness potential of other elements such as barium and strontium.

There was a problem providing the content you requested

The use of ceramic sludge and recycled glass to obtain engobes for manufacturing ceramic tiles. The conformation was formulated using a laboratory press with a capacity of 15 tons.

The chosen glass component for this procedure was the funnel glass because it presented high lead concentration.

The clay mass was obtained from the mixture of four clays that was collected after complete homogenization and removal after the rolling process. After the burn, the samples were characterized by linear retraction of burning, loss of ignition, mechanical resistance to flexion diametric compression in a universal machine of mechanical tests EMIC model DL and water absorption. Characteristics of fired bricks with co—combustion fly ashes. Ceramic materials are among those most traditionally used in the construction sector.

Recycling CRTs As stated by Okadaa material containing lead 100005 scatter and result in oral intake of the dispersed lead by humans, which ultimately results in health problems. Formulations F5 and F6 showed higher strength 5. Reducing the amount of pores favoring the reduction of water absorption and the increases of the mechanical resistance.

Waste of electric and electronic equipment WEEE includes not only the equipment itself, but also all the components, subassemblies and consumables which are part of the product at the time of discarding European Union, The procedures presented the NBR simulate the leaching that may occur to a non-sheltered waste; a flowchart of the norm is presented in Fig.

According to Menadthe lead in the CRTs is abn for the radiation shielding and for stabilizing the glass. These tailings have the potential to be used as an alternative raw material in the manufacture of abmt clay ceramics and therefore, from a manufacturing point of view, can be used as a great flux that still generates improvements in the characterization of the final product and gains in sustainable marketing.

In order to open the vacuum sealed tubes, the monitors were placed behind a wooden shield and the metallic threads were removed using a set of pliers. Journal of Cleaner Production. The technological properties evaluated were linear thermal retraction of drying and firing, loss on fire, water absorption and mechanical resistance. Based on a work at https: The samples are press with diameters of 73 mm and thickness of 15 mm identified, weighed, and measured.

A history of global metal pollution. The CRTs were split into three, according to the previous delimitation Fig. Thermochimica Actav.

Extraction and concentration of silver from waste crystalline silicon photovoltaic modules, Waste Management, 57,On line at: Ten samples were pressed for each formulation in a total of 60 samples at a pressure of 5 tons.

WEEE contains a significant number of precious metals, many of which are being recovered through different studies: June 10, ; Revised: It is a flux waste the silica base when sintered forms a liquid phase, decreases the porosity of the material, and causing a sintering faster or at a lower temperature. This dam is located in the county of Mariana and it is mainly used to retain the waste resulting from the iron ore treatment at the Germano Plant.

This statement encourages researches that aim to remove the lead from the waste CRT. The choice of the parameters used in the procedure was based on the work of Veit et al. Effect of grog addition on the technological properties of ceramic. The NBR displays a list of known hazardous materials and their characteristics and can be related to the Code of Federal Regulations title 40, subtitle of the United States 40 C.

The results from the AAS obtained from the samples that had undergone the thermal process are displayed in Table 6.

Study for vitreous waste recovery in the formulation of heavy clay ceramics

A capacidade que este mineral apresenta para adsorver metais pesados tem despertado interesse de alguns autores. September 26, ; Accepted: Revista Escola de Minas, 68 3 The higher the addition the more intense this effect. Currently produced ceramic coatings are generally composed of three distinct layers: However, this practice has caused serious environmental problems.

Porto Alegre, RS, Brazil. To determine the ideal extrusion humidity of the formulated samples, the plasticity test 10050 performed with the Standard Mass STDwith the following humidity percentages: The ceramic residue used in this work provided by a Brazilian company from Santa Catarina state from the 1005 of washing and residues of enamels.
