Изобретение относитс  к керамической промышле ности и может быть использовано в производстве фарфоровых изделий при бисквитном обжиге в стопках. Цель изобретени  - повышение качества керамического полуфабриката за счет снижени  адгезионной прочности , увеличени  в зкости и козффициента устойчивости коагул ционной структуры. Составы защитных обмазок и их фи зико-химические свойства приведены в таблице. Огнеупорную обмазку готов т см шением указанных компонентов в мешалке до однородного состо ни  и нанос т На ножку фарфорового полуфабриката резиновым валиком. Обмазк нанос т равным слоем, полуфабрикат стопируют и обжигают при После обжига остатки промазки легко снимаютс  с поверхности полуфабрика 49I та щеткой. При расстопировании изделий слипание отсутствует, дефекты поверхности не наблюдаютс . Формула из,обретени  Огнеупорна  защитна  обмазка дл  фарфоровых изделий, включающа  глинозем и латекс, отличающа с   тем, что, с депью повышени  качества керамического полуфабриката за счет снижени  адгезионной прочности , увеличени  в зкости и коэффициента устойчивости коагул ционной структуры, она дополнительно содержит метилцеллюлозу и полиакриламид при следующем соотношении компонентов в мас.%: Глинозем Латекс Метилцеллюлоза Полиакриламид 3,The invention relates to the ceramic industry and can be used in the manufacture of porcelain products in the case of biscuit roasting in stacks. The purpose of the invention is to improve the quality of the ceramic semi-finished product by reducing the adhesive strength, increasing the viscosity and the coefficient of stability of the coagulation structure. The compositions of protective coatings and their physical and chemical properties are listed in the table. The refractory coating is prepared by mixing these components in a mixer until smooth and applied to the leg of the porcelain semi-finished product with a rubber roller. The smearing is applied in an equal layer, the semi-finished product is stopped and burned. After the burning, the residual grease is easily removed from the surface of the semi-finished product 49I with a brush. When products are unmolded, no sticking occurs, no surface defects are observed. Formula: Gaining a refractory protective coating for porcelain products, including alumina and latex, characterized in that, with an increase in the quality of the ceramic semi-finished product by reducing the adhesion strength, viscosity increase and the stability coefficient of the coagulation structure, it additionally contains methylcellulose and polyacrylamide in the following ratio of components in wt.%: Alumina Latex Methylcellulose Polyacrylamide 3,
