Abstract

The invention relates to a preparation method of microcrystalline glass and particularly relates to a microcrystalline glass calendering preparation method. Raw materials utilized in the preparation method comprise feldspar, quartz, lithium feldspar, calcite, barium carbonate, magnesium oxide, zinc oxide, sodium fluosilicate, potassium nitrate, borax and cerium oxide; and a product is prepared through the following steps of: heating to melt the raw materials, calendering and molding, nucleating, crystallizing and annealing. According to the preparation method disclosed by the invention, a microcrystalline glass board which has the mohs hardness of 7 and flat appearance, and is transparent and beautiful can be obtained; and the viscosity of glass liquid in a production process is reduced and calendering equipment is not blocked.

Description

Devitrified glass calendering preparation method
Technical field
The present invention relates to a kind of preparation method of devitrified glass, be specially devitrified glass calendering preparation method.
Background technology
There is following problem in devitrified glass calendering preparation technology commonly used: 1) surface finish is poor, rough and uneven in surface orange peel is arranged and cause serious the leakage to be thrown: 2) rolling press putty often occurs, extremely expects situation.3) Bubble formation is arranged, clarifying effect is undesirable.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of devitrified glass calendering preparation method, can reach the effect of any surface finish, concrete technical scheme is:
(1) takes by weighing raw material according to following part by weight: feldspar 27.3%, quartz 15.4%, lithium feldspar 19.7%, calcite 17.1%, barium carbonate 4.3%, magnesium oxide 3.4%, zinc oxide 2.6%, Sodium Silicofluoride 4.3%, saltpetre 3.2%, borax 2.6%, oxidation Cerium 0.1%;
(2) raw material is sieved respectively;
(3) adding in the resistance furnace crucible be warming up to 1480-1520 ℃ and in 1500 ℃ of temperature ranges and kept 2 hours, is 1350 ℃ with Temperature Setting after the fusing clarification, is incubated after 30 minutes, pours bath of glass into mould inner pressure rapidly and makes type;
(4) plate shoveled and when taking advantage of sheet glass and being still golden yellow and be warming up to 650-750 ℃ of coring 30 minutes on the refractory support, then 850-950 ℃ of crystallization is 45 minutes, is annealed at last goods.
The preparation method that present method provides can obtain hardness up to Mohs' hardness 7, flat appearance, transparent microcrystal glass plate attractive in appearance, and glass metal reduced viscosity in the production process, can not stop up rolling equipment.
Embodiment
According to embodiment the specific embodiment of the present invention is described:
(1) according to taking by weighing raw material with weight: feldspar 32kg, quartzy 18 kg, lithium feldspar 23 kg, calcite 20 kg, barium carbonate 5kg, magnesium oxide 4kg, zinc oxide 3kg, Sodium Silicofluoride 5kg, saltpetre 3.8 kg, borax 3kg, oxidation Cerium 0.2 kg;
(2) raw material is crossed 60 mesh sieves;
(3) add in the resistance furnace crucible be warming up to 1480-1520 ℃ and in 1500 ℃ of temperature ranges and kept 2 hours, after fusing clarification, it is 1350 ℃ with Temperature Setting, be incubated after 30 minutes, pour bath of glass into glass plate that mould inner pressure is made type 15mm rapidly;
(4) plate shoveled and when taking advantage of sheet glass and being still golden yellow and be warming up to 650-750 ℃ of coring 30 minutes on the refractory support, then 850-950 ℃ of crystallization is 45 minutes, is annealed at last goods.
