Embodiment Construction

[0018] The glass heating mold brick according to the present invention has the components and content of 93%-99.2% of diatomite with a silicon content greater than 85%, 0-5.8% of diatomite clinker, and an iron content greater than 90%. The iron oxide red is 0.8-1.2%, and the particle size of each component is more than 300 mesh.

[0019] Depending on the use of the mold brick, different proportions can be selected. Generally speaking, the higher the content of diatomite, the better the performance of the mold brick. Therefore, the best proportion is 99% diatomite and 1% red iron oxide.

[0020] In the production process, because the sintered bricks are not neat or damaged, they can be returned to use, so the sintered diatomite clinker can be added appropriately, such as diatomite 95%, diatomite clinker 4%, oxidized Iron red 1%, or diatomite 96%, diatomite clinker 3.2%, iron oxide red 0.8%, or diatomite 93%, diatomite clinker 5.8%, iron oxide red 1.2%.

[0021] The diatomaceou...

Abstract

The invention relates to kiesel thermification swage brick. Its components are as follows: diatomite whose silicon content is over 85 percent: 93-99.2 percent, agglomerate material of diatomite: 0-5.8 percent and berlin red: 0.8-1.2 percent. Graininess of each component is over 300 items. The invention follows nether steps: feed preparation, ball mill, mould preparation, pouring, demouding, drying and agglomeration. The swage brick has merits of high temperature resistance, light quality, tenuity, softness, high intensity, little coefficient of thermal expansion, stability and etc. It can meet different requirements by means of rubbing, incision and etc. It can be widely used in glass making, glass artwork and other industries. The produced eyeglass has no motting, blue edge and distortion. Its distortion rate is less than 7 percent, which can meet quality requirement of eyeglass mould. Being able to use under 900deg.C, it is an advanced thermification mould material to produce eyeglass.

Description

technical field [0001] The present invention relates to a glass heating type mold brick and a manufacturing method thereof, in particular to a siliceous refractory glass heating type molding brick and a manufacturing method thereof. Background technique [0002] At present, the glass heating mold bricks used in my country's car mirrors are completely dependent on imports, and Japan uses volcanic ash to make them. The materials are scarce and the cost is high. Contents of the invention [0003] The object of the present invention is to provide a silicon refractory glass heating type mold brick with small thermal expansion coefficient and good cold and heat resistance stability and its manufacturing method. [0004] The silicon refractory glass heating mold brick of the present invention has the following components and contents: 93%-99.2% of diatomite with a silicon content greater than 85%, 0-5.8% of diatomite clinker, and iron-containing 0.8-1.2% of iron oxide red in an ...
