Study of the stability of a ceramic ink INTRODUCTIONPrinting inks used in ceramics are constituted of inorganic pigments dispersed in aserigraphic liquid. This liquid gives to the ink some rheological properties necessaryfor the printing process (with a screen or a flexographic roll).A good stability of ink, at rest or in use, is essential because
Redispersibility of ceramic ink characterized with SMLS Introduction Printing inks used in ceramics are constituted of inorganic pigments dispersed in a serigraphic liquid. This liquid gives to the ink some rheological properties necessary for the printing process. A good stability of ink, at rest or in use, is essential because pigments tend to settle and
EFFECT OF POLYMER ON PIGMENT DISPERSION INTRODUCTION To be able to offer a wide range of color for coating, different type of pigment are used. To insure a good cohesion between the different components and so optimize the properties of the coating in term of viscosity, polymers are added to the suspension. The aim of
Determine how clean surfaces are: Quickly and on the go Optimizing residence times in cleaning baths Time is money, and that’s also the case with industrial cleaning. Surfaces need to be cleaned until they have reached the necessary degree of cleanliness–and not longer. But how can the cleanliness of a surface be measured reliably? We
Non-invasive evaluation of protein efficiency for wine clarification Introduction In oenology, in addition to the improvement of colloidal stability and sensory properties of wine, fining is also done to clarify wine. The process consists on introducing a substance (fining agent) that induces the flocculation and sedimentation of suspended particles in a turbid wine. This critical
Fragrance influence on stability for fabric care applications Introduction Today most of Fabric Care products are liquid dispersions (laundry liquid detergent, liquid fabric softener, laundry gel, etc.) These products are constituted of many ingredients but are known to be kinetically stable. This means that the mixture remains stable through the whole shelf life without any
Effect of a fragrance on perfume formulation stability Introduction Fragrances, once introduced into cosmetic applications, can occasionally impact the cohesion and stability of end-products and lead to instabilities. It is essential to provide stable products to avoid customer dissatisfaction. In this study, the effect of different fragrances on a personal care product emulsion was evaluated
Stability of whipped egg INTRODUCTION Eggs, and more specifically whipped egg, are basic ingredients of the food industry as they enter in the composition of various recipes such as pastries, soufflé, sponge cake, etc. Whipped egg is made by whipping the egg white allowing the incorporation of air, hence the formation of a dispersion of
Study of the making of sponge cake INTRODUCTION Sponge cake is a basic pastry used in many pudding recipes. The most widely used recipe consists of whisking the egg yolk with sugar until a mousse is obtained and add the flour. In order to get a good quality pastry, the mousse, obtained after whisking the
REHYDRATION KINETICS AND STABILITY OF MILK POWDER INTRODUCTION In dairy industry, milk is often dehydrated. Indeed, milk powder has a longer shelf life than liquid milk, does not require refrigeration and as a result is easier to transport. However, dehydration must not alter milk properties; consequently, it is important to check if the rehydrated milk
