Abstract

Invenţia se referă la un prefabricat termoizolator pentru izolaţii industriale, care are în comoziţie un agregat ultrauşor, de preferinţă perlit, şi se caracterizează prin asocierea agregatului ultrauşor cu ciment portland drept liant, în raport de 2/3...3/2, şi argilă măcinată cu rol de liant şi stabilizator ceramic în proporţie de 1-3% din compoziţie, prefabricatul având următoarele caracteristici principale: densitatea aparentă de 0,45-0,55 g/cm, rezistenţă la compresiune de 1,2-2 N/mm, porozitate aparentă de 50-65%, conductivitate termică - la 400°C de 0,115-0,117 Kcal/m x h x grd., la 600°C de 0,126-0,133 Kcal/m x h x grd., la 800°C de 0,152-0,164 Kcal/m x h x grd., temperatura maximă de utilizare de 900-1000°C. Este descris şi procedeul de realizare a prefabricatului.The invention relates to a thermoisolating preform for industrial insulation, which has in its composition a ultra-light, preferably perlite aggregate, and is characterized by the combination of the ultra-light aggregate with portland cement as a binder in a ratio of 2/3 ... 3/2, and ground clay as a binder and a ceramic stabilizer in a proportion of 1-3% of the composition, the preform having the following main characteristics: apparent density of 0.45-0.55 g / cm, compressive strength of 1.2-2 N / mm, apparent porosity of 50-65%, thermal conductivity - at 400 ° C of 0.115-0.117 kcal / mxhxg at 600 ° C of 0.126-0.133 Kcal / mxhxg at 800 ° C of 0.152-0.164 Kcal / mxhx hr, maximum use temperature 900-1000 ° C. The process for making the preform is also described.
