Abstract
Przedmiotem rozwiązania jest lejna mieszanina, formierska do produkcji warstw ceramicznych form odlewniczych, która składa się z osnowy w postaci proszku ZrSiO4 o różnej wielkości cząstek ZrSiO4 5 µm ÷ 70 µm, spoiwa głównego w postaci wodnego nanokompozytu, zawierającego koloidalny Al2O3 o średniej wielkości cząstek 5 nm - 100 nm i zawartości Al2O3 40% wagowych, jednego spoiwa dodatkowego wybranego z grupy: wodorozpuszczalny poli(alkohol winylowy) albo glikol poli(etylenowy) albo metyloceluloza o lepkości 20 - 5000 mPa•s albo karboksymetyloceluloza o lepkości 20 - 3000 mPa•s albo dekstryna o lepkości 20 - 4000 mPa•s albo wodorozcieńczalna dyspersja polimerowa poli(akrylowa) albo dyspersja polimerowa poli(winylowa) albo dyspersja poli(uretanowa) ilości 6% - 15% objętościowo w stosunku do ilości spoiwa głównego, środka przeciwpiennnego w ilości 0,010 - 0,075% objętościowo w stosunku do ilości dwóch spoiw, środka zwilżającego w ilości 0,010 - 0,075% objętościowo w stosunku do ilości dwóch spoiw, przy czym udział fazy stałej wynosi 50 - 75% wagowych, a udział proszku ZrSiO4 o różnej wielkości cząstek ZrSiO4 5 µm ÷ 70 µm wylicza się ze wzoru 1, gdzie: mp - masa proszku ZrSiO4 o różnej wielkości cząstek ZrSiO4 5 µm ÷ 70 µm stanowiących osnowę, mr - masa wodnego nanokompozytu zawierającego koloidalny Al2O3 stanowiącego spoiwo główne oraz spoiwa dodatkowego, FL - udział % proszku ZrSiO4 o różnej wielkości cząstek ZrSiO4 5 µm ÷ 70 µm stanowiących osnowę. Do obliczeń zakłada się udział % proszku ZrSiO4 o różnej wielkości cząstek ZrSiO4 5 µm ÷ 70 µm stanowiących osnowę oraz masę wodnego nanokompozytu, zawierającego koloidalny Al2O3, stanowiącego spoiwo główne.The object of the solution is a slip molding mixture for the production of ceramic layers of foundry molds, which consists of a matrix in the form of ZrSiO4 powder with different particle sizes ZrSiO4 5 µm ÷ 70 µm, the main binder in the form of an aqueous nanocomposite, containing colloidal Al2O3 with an average particle size of 5 nm - 100 nm and Al2O3 content of 40% by weight, one additional binder selected from the group: water-soluble poly (vinyl alcohol) or poly (ethylene glycol) or methyl cellulose with a viscosity of 20 - 5000 mPa • s or carboxymethyl cellulose with a viscosity of 20 - 3000 mPa • s or dextrin with a viscosity of 20 - 4000 mPa • s or water-dilutable poly (acrylic) polymer dispersion or poly (vinyl) polymer dispersion or poly (urethane) dispersion of 6% - 15% by volume in relation to the amount of main binder, antifoaming agent in the amount of 0.010 - 0.075% by volume in relation to the number of two binders, wetting agent in the amount of 0.010 - 0, 075% by volume in relation to the quantity of two binders, the proportion of the solid phase being 50 - 75% by weight, and the proportion of ZrSiO4 powder with different particle sizes ZrSiO4 5 µm ÷ 70 µm is calculated from formula 1, where: mp - mass of the ZrSiO4 powder ZrSiO4 different particle sizes 5 µm ÷ 70 µm constituting the matrix, mr - mass of the aqueous nanocomposite containing colloidal Al2O3 constituting the main binder and additional binder, FL - the share of% ZrSiO4 powder with different particle sizes ZrSiO4 5 µm ÷ 70 µm constituting the matrix. The calculations assume the share of% ZrSiO4 powder with different particle sizes ZrSiO4 5 µm ÷ 70 µm constituting the matrix and mass of the aqueous nanocomposite containing colloidal Al2O3, which is the main binder.
