Abstract:
The present invention discloses zeolite 4A with molar oxide composition of 1.017Na 2 O • Al 2 O 3 • 1.973SiO 2 • 4.725H 2 O that has external specific surface area of 2.37-4.43 m 2 /g according to Brunauer-Emmett-Teller (BET) isotherm; and - external surface roughness as indicated by the ratio of RSSA/GSSA within the range of 2.58-2.81. Particles size of zeolite 4A are ranging from 0.4 μm to 5 μm, wherein 50% of all particles size are smaller than 1.45 μm, and 90% of all particles size are smaller than 2.35 μm. Invention can be used as detergent builder, ion-exchange agent, sorbent, and carrier of organic molecules.
Abstract:
The invention relates to a preparation for chemical treatment of glass, ceramic and stone surfaces consisting of esters of fatty acids, monomeric organo - silicon compounds and organic solvents. Glass, ceramic and stone surfaces treated with the invention show excellent hydrophobicity and shine. Furthermore, the application of the invention prevents damages of the treated surfaces caused by abrasion during transport, abiding of fingerprints on the treated surfaces and dust accumulation on the treated surfaces.
