Abstract
Vopseaua refractara pentru miezuri si forme de turnatorie, conform inventiei, este constituita dintr-o componenta refractara de baza, cuprinzînd silicat de ziconiu sau/si termocorindon si care, luate separat, pot eventual fi amestecate cu cuartita si respectiv cu caolin si din adaosuri de minimum, respectiv 1,5% bentonita activata, 0,5% hexametafosfat de sodiu si 0,3% alcool polivinilic, cît si de amidon pregelifiat. în scopul realizarii unei pelicule aderente cu rezistenta ridicata la socuri termice, vopseaua contine maximum, respectiv 4% bentonita activata, 2% hexametafosfat de sodiu si 2% alcool polivinilic, 0,3-2% amidon pregelifiat si componenta refractara pe baza de rest, pasta obtinuta fiind diluata cu apa pentru aplicare, la densitate de 1,45-2,000 g/cm3.
