Abstract: This paper considers the use of lignin during the preparation of phenol-formaldehyde resins. The effect of lignin on the properties of phenol-formaldehyde resins and materials based on them is studied. The obtained resins are characterized by differential scanning calorimetry (DSC). The results show that, in the case of increasing the con...

The research purpose is to develop methods for determination of heat losses in drying cylinders. Experimental study of temperature of drying cylinders performed in the drying section of a paper machine during its steady-state operation. Medium, maximum and permissible statistical characteristics of drying cylinder temperatures were defined. The dry...
В данной работе экспериментально и теоретически исследованы тепловые потери через торцевые крышки и от повышенного содержания конденсата в сушильном цилиндре. Рассмотрена экономия греющего пара при теплоизоляции торцевых крышек. / In this work, the heat losses through the end caps and from the increased content of condensate in the drying cylinder ...
The circulating lubrication system of drying cylinders has a branched spatial structure with a heat exchanger to reduce the temperature. With the reduction of heat losses during contact drying of paper will decrease the temperature of the distribution and discharge tubes. For this purpose it is necessary to install thermal insulation of end caps of...

This experimental and modelling study provides a general overview of the acoustical performance of hemp-lime and hemp-clay for building thermal insulation at the material scale. It is based on statistically robust experimental results from more than 100 hemp-clay samples, together with the analysis of a large hemp-lime database. In hemp-clay mixes,...

Silica aerogels are amongst the lightest mesoporous solids known and well recognized for their superinsulating properties, but the weak mechanical properties of the inorganic network structure has often narrowed their field of application. Here, the inherent brittleness of dried inorganic gels is tackled through the elaboration of a strong mesoporo...

This paper deals with summer thermal comfort. "Human thermal comfort is the state of mind that expresses satisfaction with the surrounding environment" according to ASHRAE Standard 55. Thermal comfort depends on air velocities, radiant temperature and humidity... Most important for thermal comfort is the so called operative temperature. This is the...
