Abstract
Procedeul de tratare a carbonatului de calciu, obtinut prin precipitarea în mediu omogen sau eterogen, conform inventie cinsta în aceea ca, în scopul asigurarii unei bune compatibilizari cu compoundurile pe baza de policlorura vinil, carbonatul de calciu supus tratarii sub forma de suspensie continînd 15.....20% carbonat de calciu se încalzeste la temperatura de 90........95 degree C, dupa care se se adauga sub agitare o solutie aproximativ 4% sapun alcalin de seu corespunzator unei proportii de 1,2........1,5% acid gras fata de carbonatul de calciu produs finit si apoi dupa aproximativ 20 min, produsul se separa si se usuca la o temperatura cuprinsa în intervalul 130....150 degree C.The process of treating calcium carbonate obtained by precipitation in a homogeneous or heterogeneous medium according to the invention is characterized in that, in order to ensure good compatibility with the polyvinylchloride compounds, the calcium carbonate subjected to the slurry treatment containing 15. ... 20% calcium carbonate is heated to 90 ° C to 95 ° C, after which a solution of about 4% alkaline soap corresponding to a proportion of 1.2 1.5% fatty acid to finely produced calcium carbonate and then after about 20 minutes, the product is separated and dried at a temperature in the range 130-150 ° C.
