摘要:
Disclosed are an environmentally-friendly glass composition for laundry detergents and washing supplements, and a method for manufacturing a glass powder thereof, wherein the glass composition is a borate glass containing large amounts of K2O and Na2O and a small amount of SiO2, and the elution properties of ions are maximized, thus enabling the production of a high concentration of elution water. As a result, the present invention uses to advantage the low chemical durability of borate glass, which is a major disadvantage of borate glass, and thereby maximizes the elution properties of the glass to form a large amount of OH− ions and B(OH)4− ions within a short period of time, and thus can exhibit excellent washing power during the washing of laundry.

The disclosure is directed to glass frits materials containing phosphors that can be used in LED lighting devices and for methods associated therewith for making the phosphor containing frit materials. Suitable non-lead glasses have a composition, in mol %, in the range of 20-24% K2O, 8-12% ZnO, 2-6% Al2O3, 35-41% B2O3 and 22-28 SiO2. Suitable leaded glasses have a composition, in wt %, in range of 72-79% PbO, 8-13% Al2O3, 8-13% B2O3, 2-5% SiO2 and 0-0.3% Sb2O3. Commercial high-lead glass can be used in practicing the disclosure. Among the unique advantages are the ability to blend two or more phosphors within the same frit layer which will yield a multi-phosphor-containing glass after firing; the ability to deposit the phosphor onto a substrate into a desired geometric pattern; and the fluorescing layer can be applied to the active plane, with the glass serving as protective substrate.
