South Africa opens nanomaterial facility

first_img7 December 2015A state-of-the-art facility to produce nano-structured materials for industrial testing was opened at the Council for Scientific and Industrial Research (CSIR) in Pretoria on 3 December.The Nanomaterials Industrial Development Facility was opened by the Department of Science and Technology (DST) in partnership with the council. The new establishment will benefit the plastics and cosmetics industries, among others, to develop new nanotechnologies and processes. Science and Technology Minister Naledi Pandor said it would provide the capabilities for the industrial-scale production of nano-structured materials.“All the facilities supported under the Industry Innovation Programme, including the Nano-materials Industrial Development Facility, have the potential to play a role in the development of high-technology small, medium and micro enterprises,” she said. “This facility could enable such enterprises to take advantage of the rapidly growing international market in nano-structured materials and nano-composites.”Some of the activities of the nanomaterials centre at the @CSIR @dstgovza #ncnsm pic.twitter.com/B9QVWlLKMx— Veronica Mohapeloa (@MaVeroza) December 3, 2015About nanomaterialsNanomaterials are chemical substances or materials that are manufactured and used at a very small scale – they can be scaled down to 10 000 times smaller than the diameter of a human hair.They are developed to display new characteristics, such as increased strength, chemical reactivity or conductivity, compared to the same material without the nanoscale feature.How the centre will helpThe newly launched centre will assist to increase overall industry competitiveness.The plastics industry is one sector that will reap rewards from the facility. “The addition of nanomaterials in the manufacturing of plastics can significantly enhance the mechanical properties of plastics,” said the CSIR. “Plastics can, for example, be made stronger, lighter and more fire and ultraviolet resistant.”Min Pandor gets an explanation of how this machine works with nanoclays at the Nanomaterial centre @csir @dstgovza pic.twitter.com/UyiuxQM3ZI— Veronica Mohapeloa (@MaVeroza) December 3, 2015“Addressing the technological development of the plastics industry will enable the industry to keep up with international trends, both in the level of advanced materials used, and in the machines and processes used to produce plastic components and systems,” it added./p>The CSIR performed research to stimulate and improve the competitiveness of industry and thereby contribute to the economy of the country, explained the council’s chief executive officer, Dr Sibusiso Sibisi.“We need to think differently,” he said. “We need to explore new ways and mechanisms to enter areas of activities such as the beneficiation of our natural resources to create jobs, manufacture high-end components and export them.”The facility houses infrastructure processing and testing and it will play a crucial role in developing skills and transferring technologies to industry.Rising fieldThe international market in nano-structured materials and nanocomposites was growing rapidly, said the CSIR. Nanoclay composites are expected to increase from a 2011 volume of 24 million to 74 million metric tonnes and a global value of $3-billion by 2016.In South Africa, the total plastic consumption is in the order of 1.3 million metric tonnes or R35-billion a year, and accounts for an estimated 3.2% of the manufacturing sector.Source: CSIRlast_img read more

Building Science Corp. Study Examines Insulation Performance

first_imgOld newsThe findings aren’t new; they were reported by GBA in a September 2012 article called “Air Leakage Degrades the Thermal Performance of Walls.” In that article, senior editor Martin Holladay wrote, “If the walls were sealed and there was no air flow through the walls, all of the R-13 walls behaved the same. As Gertrude Stein might have put it, an R-13 wall is an R-13 wall is an R-13 wall. ‘When the nominal R-13 walls are sealed and tested, they have the same heat flow, plus or minus 4%,’ said [Chris] Schumacher. ‘They all perform roughly the same.’” RELATED ARTICLES Builders who run the other way when someone suggests using fiberglass batt insulation may want to rethink their point of view. A study released by an industry trade group says that one type of wall insulation performs as well as any other as long as it is installed correctly and the wall has been air-sealed.That conclusion comes from an updated Thermal Metric Summary Report compiled by the Building Science Corporation and released this week by the North American Insulation Manufacturers Association (NAIMA), a trade group representing manufacturers of fiberglass, rock wool, and slag wool insulation.“R-value is R-value,” NAIMA said in reporting the latest results of the multi-year study. “When walls are constructed to the same R-value and properly sealed, all insulation types perform essentially the same.” Air Leakage Degrades the Thermal Performance of WallsA Bold Attempt to Slay R-ValueUnderstanding R-ValueInstalling Fiberglass Right Search continues for an R-value replacementThe industry-funded research is part of what’s turning out to be a very long process aimed at replacing R-value with another metric for describing thermal performance.Joseph Lstiburek, a principal at Building Science Corporation (BSC), announced in 2007 that it was time for the R-value to be retired and replaced with a metric that took into account more complexities of building assemblies and site conditions. As GBA’s Martin Holladay reported nearly four years ago, BSC built a new test rig called a double-guarded hot box with the aim of measuring heat and mass flows. But testing dragged on for years without any firm conclusions.As the report notes, BSC joined with six companies in the industry — including NAIMA and Icynene, a manufacture of open-cell foam — to develop a replacement for R-value.“The Thermal Metric Project was initiated in response to renewed focus on building system performance and increasing use of a broader range of building materials and systems,” the report notes. “These factors highlight the shortcomings of the dominate thermal performance metric, namely R-value. Contemporary insulation materials and systems are more or less sensitive to thermal bridging, workmanship (i.e. quality of installation), internal convention and through convection (i.e. infiltration, exfiltration, wind washing and re-entrant looping).“The impact of such ‘anomalies’ and ‘defects’ is not captured in the standard (label and installed) R-value metric,” it said.Researchers still have more work to do: “At this stage of the research project, the industry partners have not proposed a new metric for quantifying the thermal performance of insulation beyond conventional R-value,” NAIMA said, “and the report does not include any recommendations for a new metric.”But the study did yield a number of observations:Unless a continuous layer of insulation is installed on one side of the wall, all wood-framed walls are subject to thermal bridging, regardless of what type of insulation is used in the stud cavities. Thermal bridging through the framing lowered thermal performance by about 15%.Commercially available heat transfer models do a good job of predicting thermal bridging, as did the ASHRAE Handbook of Fundamentals.All types of insulation show changes in thermal performance with changes in temperature.No matter what type of insulation is used, all wall assemblies show some loss of thermal performance when air is permitted to move through them. A preliminary version of the report was released almost two years ago, NAIMA said, comparing fiberglass batts, cellulose, closed-cell spray foam, and foam sheathing. But open-cell spray foam wasn’t included because of defects in a test wall. The updated version of the report, dated June 2015, also includes test results involving R-15 fiberglass batts and R-15 blown-in fiberglass insulation.NAIMA said that R-15 fiberglass batts performed better than a wall insulated to R-13 with open-cell spray foam and better than R-12 worth of closed-cell foam.“The results of this research clearly demonstrate that there is no single ‘best’ insulation material and that all insulation materials perform equally well when properly air sealed and installed, debunking the claims that spray foam insulation performs better than other insulation types and provides air sealing for the whole building.”last_img read more
