Starch is a natural polymer found in many processes either as an adhesive or a thickener. Following paper production, corrugated board is the second largest application of non-food starches globally, where it it used as an adhesive between the fluting and liners. The control of the adhesive viscosity during process and storage is critical. However, despite further developments regarding the formulation of starch adhesives, the viscosity is commonly not stable enough over extended periods of time, in particular over weekend storage. In this first of a series of blog posts with the corrugated boards application as the example, I will give an introduction to this problem, and the new technology of Exilva, a microfibrillated cellulose, to solve it.Read more
Modified polyurea and Exilva Microfibrillated cellulose (MFC) can both be used as rheology modifier 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 & anti-sedimentation behavior. Tune-in on a comparison between these two rheology additives.
Clay (including montmorillonite and bentonite) additives and Exilva microfibrillated cellulose (MFC) have a lot in common since they both can be used as rheology modifier in different industries. However, there are also clear differences. In this article, I will review the ability of the materials to provide yield stress and subsequent anti-settling & anti-sedimentation benefits. Tune-in on a comparison between two of the most potent anti-settling & anti-sedimentation additives available.
Exilva microfibrillated cellulose and fumed silica are both used for controlling the rheology of liquid systems, such as anti-settling and anti-sedimentation. But when we are comparing the two technologies, we also see differences. In this article, we will show you how the microfibrillated cellulose and fumed silica builds yield stress, and how they consequently can give good anti-settling and anti-sedimentation benefits.
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?
In China we are currently seeing a massive shift towards sustainable technologies. Many are describing China as the next green superpower, and that China is positioning itself towards a new area where the accessibility to energy is becoming very different from the current situation. This can shift the power balance towards economies which embrace the new opportunities from more sustainable solutions. Where can you find opportunities in this? And are there opportunities for novel sustainable materials like cellulose fibrils and microfibrillated cellulose (MFC)?
Solving problems you have or initiate new innovations can lead down quite different paths. Sometimes the urge to get rid of a problem can lead to many quick decisions, but what should one really look for in these types of situations? Should your standard tool box of problem solvers be used, or do you have the opportunity to focus on upgrading this box? In this blog post, I will try to show you some concrete examples why adding new tools to your tool box can improve your functionalities beyond your scope, using the microfibrillated cellulose as an example. Simply, why new functionality beats substitution.
Coating performance is often very complex, and can depend on the coating system itself, substrate to be coated, conditions during coating etc. Increasing the performance is often a lengthy process with multiple tests on wet paint performance and dried coating performance. Key aspects of wet paints can be control of rheology, and for solid coatings the ability to improve endurance. Are there technologies available for aiding on the key aspects? For sure. Are there new sustainable additives which can improve the new water borne technologies? Let me show you an example of exactly that in this blog post.
Once you have taken the decision to strengthen your business based on organic growth you have already taken a very important strategic step. At the same time, you have placed yourself at the gambling table, because with all new opportunities comes a risk. But how can you take measures to control this risk and mitigate it as much as possible? Here are some practices you can utilize when looking for technological enablers to your new bio-based innovations.
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?
