Abstract:
The present invention relates to a porcelain batch composition for a hygienic pottery, an insulator, a dish, etc. containing alkali-free alumina borosilicate-based display cullet or waste glass used in a liquid crystal display, an organic light-emitting diode display, etc. as a raw material. More particularly, the present invention provides a porcelain batch composition for a hygienic pottery, an insulator, a dish, etc. containing alkali-free alumina borosilicate-based display cullet or waste glass as a raw material, wherein the batch composition includes kaolin, clay, agalmatolite, pottery stone and feldspar, and wherein the batch composition includes 0-30 parts by weight of the feldspar and 3-33 parts by weight of the alkali-free alumina borosilicate-based display cullet or waste glass based on 100 parts by weight of the kaolin, the clay, the agalmatolite, the pottery stone or a mixture thereof. With respect to cullet or a display panel generated and discarded during a glass manufacturing process of a liquid crystal display of a thin film transistor or an organic light-emitting diode display, waste glass generated during a commercial production process of a display panel, or waste glass generated during discarding a display panel after terminating the durability life thereof, a recycling method was found and applied practically to decrease the generation of waste. A porcelain raw material having high quality may be provided at low costs when compared to a natural raw material used in a common porcelain manufacturing process such as a hygienic pottery, an insulator, a dish, etc. Thus, the unit manufacturing cost of a porcelain batch composition may be decreased, and the physical properties of final porcelain may be improved.
Abstract:
PURPOSE: A method for partially chemical-strengthening glass and partially chemical-strengthened glass are provided to apply salt-paste on a part of the glass in order to cut the glass using a salt-paste non-applied part. CONSTITUTION: One side or both sides of glass is masked using a salt-paste applying method in order to chemical-strengthen the glass. The glass is divided into a chemically-strengthened part(A) and a non-chemical-strengthened part(B). The chemical-strengthened part is 50-99% of whole surface area of the glass. The glass is cut along the non-chemical-strengthened part. Salt-paste for the salt-paste applying method includes ethanol-based oil.
Abstract:
PURPOSE: A batch composition of borosilicate based roving fiber glass is provided to lower melting temperature of robbing fiber glass batch and to reduce manufacturing cost of the roving fiber glass by including cullet of non-alkali alumina borosilicate based display glass. CONSTITUTION: A batch composition of borosilicate based roving fiber glass contains 66-470 parts by weight of cullet based on 100 parts by weight of talc among the batch composition. The cullet is one selected from non-alkali alumina borosilicate based cullet for organic light-emitting diode and nonalkali alumina borosilicate cullet for thin-film transistor liquid crystal display. The batch composition includes 0-11 parts by weight of colemanite, 74-216 parts by weight of limestone, 0-8 parts by weight of borax, and 0-4 parts by weight of soda ash based on 100 parts by weight of the talc on top of the non-alkali alumina borosilicate based cullet. The section diameter of the roving fiber is 15-30 μm.
