Abstract

The present invention discloses float process of producing jade spar. The jade spar is produced with the material including SiO2 55-75 wt%, Al2O3 2-10 wt%, B2O3 0.3-3 wt%, CaO 2-8 wt%, MgO 0.1-0.5 wt%, ZnO 2.0-6 wt%, K2O 1-5 wt%, Na2O 5.5-15.7 wt%, and F 3-9.25 wt%. The float process of producing jade spar plate has easy control of the plate sizes and low production cost.

Description

A kind of production method of large-block high-speed microcrystalline stone
Technical field
The present invention relates to a kind of finishing material, is that a kind of floating process that utilizes is produced beautiful spathous method specifically.
Background technology
Beautiful spar is that a kind of low iron mineral raw material of multiple high brick of selecting for use is through high temperature melting, having that the coring of grinding and polishing light forms is translucent, smooth exquisiteness, the high-tech building and ornament materials that exactly like white jade, it is the novel senior environment friendly stone that a kind of multinomial physical and chemical index all is better than natural granite, its maximum characteristics are whole pore-frees, there is not assorted spot, radiationless, nondiscoloration, zero water-intake rate, elegant and poised, gloss is simple and elegant soft and graceful, exquisite in texture, especially white " beautiful spar " is taken the course of its own especially, it is interior wall face, ground, the substitute products in senior finishing such as table top place, all right hot bending of this material, make high-grade sanitary ware etc.The producer that produces both at home and abroad seldom at present, it adopts the rolling process explained hereafter mostly, after this technology disadvantage is exactly formed product, owing to influenced by the smooth finish of stack own, planeness limitation, destroyed any surface finish that glass surface tension can produce in natural moulding, increased and to have carried out grinding and polishing to it and handle this deep processing operation, promptly increased production cost, destroyed the original shock-resistance of this product again.
Summary of the invention
The present invention is directed to the problem in the above-mentioned beautiful spar production technique, created one and will roll crystallite technology and the float glass process moulding process beautiful spar of the grafting novel method of producing mutually.
Technical solution of the present invention is: the beautiful spar raw material liquation that melts in certain temperature, flow in the molten tin bath under the viscosity, the good bigger tin liquor of proportion of fusing is arranged in the molten tin bath, beautiful spar liquation swims on the tin liquor, the pull speed that is being complementary, edge machine speed (graphite shelves wall is piled up angle), under the acting in conjunction of beautiful spar flow stream velocity, formation has the beautiful spar band of certain width and thickness, its belt surface is when shrinking, under capillary effect, naturally polishing moulding, finish nucleating course simultaneously, and then enter in the annealing furnace, annealed elimination internal stress is produced qualified beautiful spar sheet material liquid drawing and is made it moulding by this liquid level, and then annealed, produce qualified beautiful spar sheet material.The adjustment of beautiful spar molding thickness can be selected graphite shelves wall and two kinds of forms of edge machine for use.
Described beautiful spar glass metal is through certain proportioning raw materials, in glass melter, makes behind the thorough mixing through 1300 ℃ of-1550 ℃ of high temperature melting,
Described annealing is meant beautiful spar glass ribbon is entered annealing furnace by the roller-way machine under 700 ℃ of-600 ℃ of temperature environment, carry out uniform decrease in temperature through suitable temperature regulation, process with the destructive permanent and temporary transient two kinds of stress of having of eliminating that glass ribbon produces in inhomogeneous cooling makes sheet glass have certain resisting breakage temperature.
Described beautiful spar liquid component proportioning is as follows:
The title weight percent
SiO 2 55-75
Al 2O 3 2-10
B 2O 3 0.3-3
CaO 2-8
MgO 0.1-0.5
ZnO 2.0-6
