Definitions
- the present invention relates to a raw material composition for soda-lime glass, and particularly to effectively suppress the formation of nickel sulfide (NiS) in a glass base when the glass raw material is melted.
- the present invention relates to a raw material composition of soda-lime glass capable of obtaining quality glass products.
- Such a plate made of soda-lime glass is quenched after being heated to its softening point (around 600 ° C) in order to be processed into tempered glass for building or automobiles. As a result, a compressive stress is generated in the surface layer of the glass plate.
- NiS nickel sulfide
- the phases cannot exist stably at room temperature, they are stable at room temperature over time. With this phase transition, NiS expands in volume. Since the tempered glass sheet has a tensile stress layer in about 2/3 of the inner part in the thickness direction, cracks (breakage) rapidly develop due to the volume expansion of NiS in the tensile stress layer. This leads to natural damage of the glass plate.
- the tempered glass returned to the glass is inserted again into the firing furnace (soak furnace), reheated and held for a certain period of time, so that Ni S contained in the tempered glass becomes unstable ⁇ .
- the phase transition from the phase to the / 5 phase which is stable at about 300 ° C or less, causes volume expansion and forcibly breaks the reinforced glass, thereby rejecting defective products containing foreign matter of NiS.
- There is a known removal method this is called soak processing).
- the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to effectively suppress generation of nickel sulfide (NiS) during melting of a glass raw material.
- An object of the present invention is to provide a raw material composition of soda-lime glass which can be used.
- Another object of the present invention as a coloring component in the glass material traces of ferric oxide (F e 2 0 J), Selector emission (S e), Se re um (C e), or other
- An object of the present invention is to provide a raw material composition of soda-lime glass that can effectively suppress the generation of NiS when a glass material is melted when a metal material is contained. .
- Nickel sulfide (NiS) contaminants present in soda-lime-based glass include metal particles containing Ni mixed in glass raw materials and Ni components in stainless steel used in melting furnaces. Is produced during the vitrification reaction under high temperature with the sulfur (S) component in Na 2 S 0, used as a glass raw material. If a small amount of metal oxides, chlorides, sulfates or nitrates is added to the glass material in advance, the reaction between Ni and S during melting: the formation of NiS , Can be reduced or completely eliminated.
- NiS becomes a eutectic compound with other metals to lower the decomposition temperature, and the metal chloride, sulfate, or It is thought that when a small amount of nitrate is added, the oxidizing action is promoted and it becomes difficult to generate sulfide of Ni, and as a result, generation of NiS is suppressed.
- a glass raw material containing sodium sulfate contains an additive made of a metal oxide, chloride, sulfate or nitrate. I do.
- the composition contains sodium sulfate (Nai SO,), and contains ferric oxide (Fe! 03), selenium (Se), cerium (Ce), or another metal. It is characterized in that the glass raw material contained as a coloring component in the material contains an additive comprising a metal oxide, chloride, sulfate or nitrate.
- the metal may be tin (Sn), iron (Fe), cobalt (Co), manganese (Mn), lead (Pb), lithium (Li), potassium (K) or natrium. It is at least one member selected from the group of tritium (Na). In this case, the weight percentage of the additive with respect to the total weight of the glass raw material can be 0.15% or less.
- the frequency of the presence of NiS foreign substances in a float-type melting furnace used in practice is about one per 10 tonnes (t) of glassware.
- the amount is also very small, not more than ⁇ ⁇ ⁇ m (0.001% by weight). Therefore, the amount of the metal oxide or the like added to the glass raw material is extremely small, and the present invention has a sufficient effect on the reduction or complete disappearance of nickel sulfide (NiS). It is possible to obtain BEST MODE FOR CARRYING OUT THE INVENTION

It was inserted into the held electric furnace and the temperature was raised to 140 ° C in 10 minutes. Further, after holding at this temperature for 2.2 hours, the sample was taken out of the electric furnace and cast, and was used as sample glass 1.
- Table 2 shows the addition ratio of Ni (wt%), the maximum particle size of Ni S ( ⁇ m), and the number of Ni S per glass weight (pieces / g) in sample glass 1. It was done. The number of Nis was measured using a stereo microscope.
- Tin oxide (Sn0,), an oxide of tin (Sn), is added to one set of glass raw materials to adjust the glass raw material containing Ni metal powder and SnO; Then, it was used as glass raw material 2. Similarly, 1 to 4096. Tsu the glass raw material of the bets, was added iron (F e) oxide in which iron oxide (F e! 03), containing the N i metal powder and F e 0 3 The glass raw material to be used was adjusted to be glass raw material 3.
