Refractory materials are fabricated in two forms: shaped and unshaped (monolithic) refractories. Shaped refractories include fired and unfired materials with predetermined shapes, precast shapes and fusion cast refractories. Monolithic materials include plastic mixes, castables, ramming materials, dry vibratable, gunning materials, fettling materials, coatings and mortars. Monolithic materials differ from refractory bricks in that they are not shaped and fired before use. These materials do not have high energy requirements, are more readily available, take shorter times to install, can be repaired locally and require less manpower.
Clay conditioners can bring several benefits to your production process, but how can you measure effectively its effects on your specific process? We have asked this question to our R&D experts in the ceramic lab and this is what they have answered.
Registration, Evaluation, Authorisation & restriction of CHemicals (REACH) is a regulation that aims to make the handling and commercialisation of chemicals safer. In this blog article we talk about how this regulation affects heavy clay manufacturing in particular.
For many years, bentonite has been introduced in ceramic bodies to enhance plasticity in an economic way. However, its use in ceramics is not only bringing advantages but also some inconveniences related to its ability to increase plasticity. Its layer structure is responsible for these properties.
Once you have decided that using a clay additive will be the best solution for your production problem, you have to decide what quantity is the best for your specific production process.
Blake Stacey, technical consultant in Real Material Solutions (https://real-mat-sol.com) who has worked for many years in the ceramics sector, has written a testimony about solving production problems and finding the best way to work with the difficult clays on Western Australia. Here we share some of his thoughts:
One of the most frequently asked questions we get is where to introduce the clay additive during the manufacturing process. This month we will recommend you where to place your conditioner.
Structural bricks provide greater insulation, more protection from the elements, and the appeal and durability that have always made clay brick a desirable building material. The manufacturing of large structural clay brick presents challenges to brick makers in two of the critical processes involved in brick making, extrusion and drying. In this blog we will focus on the drying part of the process.
Last week Munich hosted one of the largest ceramic exhibitions: Ceramitec 2018. From 10-13 April the international ceramics industry gathered around the exhibition, which was, in general terms, really successful. In case you couldn't attend, we were there to be able to show you.
When it comes to the use of ceramic additives, we must be 100% sure that the one that we are using is the best for their production process. We have talked about different ways to optimize ceramic production processes in several blog articles and we even wrote a blog post on the benefits of using additives in a brick production. However, we have received many questions about how additives can affect a manufacturing process. We will try to answer all of the questions as well as we can. This month's question is: "will the additive block my extruder if there's a production break?"
