Hydroxyethyl cellulose (HEC) and Exilva microfibrillated cellulose (MFC) can both be used as rheology modifiers in a variety of industries to prevent sedimentation and settling. In this article, I review the ability of the materials to give a yield stress in a waterbased system and, because of that, provide anti-settling and anti-sedimentation behavior. Tune-in on a comparison between these two rheology additives.Read more
The pursue for a more efficient and increasingly EHS improved way of incorporating microfibrillated cellulose into polymers for polymer melts (thermoplastics) has been going on for years. Thermoplastics are an important source for many final products and applications. By introducing microfibrillated cellulose into polymers by the means of liquid suspension, Gneuss have been able to avoid the agglomeration of powder form similar particles, as well as improve the EHS profile of such a process.
What is heat of hydration, and how does it affect the settling and curing phase of the concrete? Learn more about different types of concrete cracking, why they occur - and preventative measures and repair methods for fixing it in this Topic Tuesday. Hint: there are bio-based alternatives available!
Gypsum boards (plasterboard/drywall) are a very commonly used product in the construction industry. Currently, the production of the boards is a labor-intensive, CO2 producing and energy consuming process with the need for many synthesized additives to retain the flow, strength and setting profiles. What if you could change that?
Over the last century, human activities have been affecting the global environment, most noticeably with the general increase in greenhouse gases, such as carbon dioxide (CO2). This rise in greenhouse gases has mainly been due to the upsurge in fossil fuel consumption over the last fifty years. This consumption has had a knock-on effect with global temperatures, with a general increase of 1°C over the last century and this is projected to rise by 2°C over the next century.1 This increase in temperature has also affected climate change by giving more extreme weather conditions. But how has this affected the construction industry? Have we been developing alternatives that could point us in a more bio-based direction?
We rely on well-proven construction technologies wherever we move around. The construction technologies have been developed for decades to make sure that we have long-living and safe infrastructure and buildings around us. But in a world moving in increasing speed towards more emphasis on lowering emissions and waste, how is the construction industry affected? And are there any ready-made bio-based solutions available?
The technology of cellulose fibrils/nanocellulose is breaking new grounds, and my research review this week is focusing on materials development. So if you are wondering how new increasingly sustainable nanocellulose/thermoplastic solutions are looking, you should not miss out on this week’s research review!
Lime, consisting of air lime and hydraulic lime, is one of the most important historical construction materials. Due to new plasticizer technologies available, we are now seeing a new golden era approaching for this material? Don't miss out on this Topic Tuesday subject that can give you insights into improving lime mortar formulations which can outcompete concrete materials by enhancing workability and appearance.
Trends are clear; today's technology demands expect smaller and lighter devices, while at the same time the need for digital speed, pace and stamina is a potential deal breaker. How do you cope with this when developing tomorrows technology? In today's Topic Tuesday we serve you some interesting thoughts on how to keep your batteries safer, so you can focus on staying in front in the ongoing development marathon.
Concrete products are a complex mixture of chemicals, fines, and heavy particles. It's always challenging to control the stability, flow and strength of it. Many admixtures have been created to overcome these challenges, often containing synthetically derived performance additives. I will here try to give you some input of one of the new technologies and how it affects various parameters in the concrete.
There is a growing interest to increase the portion of bio-based components in various consumables. We have previously discussed about the challenges to incorporate microfibrillated cellulose (MFC) into composite materials with hydrophobic matrixes, such as PLA. Today we will take a step even further and see how cellulose fibrils can support the development of more environmentally friendly tires with high performance and durability.
