The surface properties of faience—acidity and aluminosilicate modulus—are determined and their variation depending on the chemical composition on changing the content of mullite Al2Si2O5, quartz, and cristobalite (crystalline modification of quartz SiO2) is explained. In accordance with the structure of the surface, the presence of a negative surface charge was determined. It was established that silanol groups on the surface of Si–OH faience, which are weakly acidic, afford a physicochemical interaction with polymer film-forming materials, possessing basic properties. The sorption of urea-formaldehyde oligomers of various compositions on faience and subsequent film formation in the presence of polyvinyl alcohol are considered.

脲醛树脂在多孔陶瓷上的吸附研究

确定了彩陶的表面特性——酸度和铝硅酸盐模量——并解释了它们的变化取决于改变莫来石 Al 2 Si 2 O 5、石英和方石英(石英 SiO 2 的结晶变体)含量的化学成分。根据表面的结构,确定存在负表面电荷。已经确定,Si-OH 彩瓷表面的硅烷醇基团呈弱酸性,可与聚合物成膜材料发生物理化学相互作用,具有基本性质。考虑了各种组成的脲醛低聚物在彩陶上的吸附和随后在聚乙烯醇存在下的成膜。
