Problems solved by technology

When the glass melt flows through the metal diversion groove, it is easy to react with the metal diversion groove and corrode the diversion groove. At the same time, the high-temperature glass melt will decompose the organic lubricating oil applied in the groove, producing a large amount of toxic smoke, seriously Affect the health of operators and the working environment in the workshop
[0003] Some manufacturers use high-temperature resistant inorganic materials such as silicate refractory bricks and alumina refractory layers to reduce the degree of corrosion and the generation of toxic fumes. However, in addition to silicates, glass manufacturing raw materials also contain sodium sulfate and nitrate substances. When the raw material is melted, it is easy to generate alkaline hydroxide and sulfide, which is highly corrosive to this type of coating. At the same time, because the glass melt brings the substance of the inorganic coating into the melt, the smoothness of the glass product is caused. , transparency and other quality defects

Embodiment 1

[0010] Example 1 Mix 90% by weight of flaky graphite with a fineness of 300 mesh and 10% of liquid epoxy resin evenly, adjust the water content of the mixture, and then smear it on the surface of the semicircular cast iron diversion tank with a thickness of 3mm , and smooth the surface of the graphite layer, and then dry it at a high temperature of 300°C until no more smoke is generated.

Embodiment 2

[0011] Example 2 Mix 95% by weight graphite powder with a fineness of 400 mesh and 5% liquid phenolic resin, adjust the water content of the mixture, and then smear it on the surface of the aluminum alloy diversion tank with a thickness of 5mm. The surface of the layer is compacted and smoothed, and after drying, it is dried at a high temperature of 400°C until no more smoke is produced.

Embodiment 3

[0012] Example 3 Mix graphite powder with a fineness of 90% by weight and 600 mesh graphite powder with 10% liquid epoxy resin, adjust the water content of the mixture, and then smear it on the surface of the stainless steel diversion tank with a thickness of 4mm, and place graphite The surface of the layer is compacted and smoothed, and after drying, it is dried at a high temperature of 30,000°C until no more smoke is produced.

Abstract

A guide chute of molten glass used to make glass bottle is composed of a basic metallic chute and a graphite layer on the surface of basic metallic chute. It is prepared through proportionally mixing graphite with liquid resin, coating the mixture on the surface of basic metallic chute, and high-temp treating at 300-400 deg.C. Its advantages are high flow speed and high molten glass quality.

Description

technical field [0001] The invention belongs to the field of accessories of glass bottle making machines, and in particular relates to a flow guide groove for molten glass. Background technique [0002] At present, the guide devices for glass melt in general-purpose bottle-making machines are all made of cast iron or aluminum alloy. In order to increase the flow performance of the melt, it is necessary to apply organic matter such as lubricating oil or engine oil in the metal guide groove. Glass making raw materials are melted into molten glass in a glass melting furnace, and then sent to molds or forming devices through flow guiding devices to manufacture various glass products such as glass bottles. When the glass melt flows through the metal diversion groove, it is easy to react with the metal diversion groove and corrode the diversion groove. At the same time, the high-temperature glass melt will decompose the organic lubricating oil applied in the groove, producing a la...
