Abstract

Винахід належить до способу одержання водної суспензії на основі сульфату кальцію. Згідно способу одержують кашку сульфату кальцію, використовуючи принаймні першу, регулюючу в'язкість добавку, що містить сополімер, який одержують з мономерів етилену принаймні двох різних типів, перший з яких включає мономери етилену з фосфатною або фосфоновою функцією. До того ж додають другу, регулюючу в'язкість добавку, що включає фосфат або поліфосфат лужного металу, причому кількість регулюючої в'язкість добавки, яка додається, так, що в'язкість складає 250 – 2500 мПа м з, переважно 500 – 2000 мПа м з, і концентрація складає 60 - 77% твердих речовин, переважно 66 – 72 %.
