Description
Technical field
The present invention relates to glass-ceramic, specifically a kind ofly utilize glass-ceramic raw material that the scrap glass pottery makes and with the method for its production glass-ceramic product.
Background technology
Glass-ceramic has another name called " opaque glass ", " devitrified glass ", is to be smelted into parent glass with quartz as main raw, through fluoridation, makes product (as cup, dish, bowl etc.) the similar pottery of making of outward appearance, and functions of use is comparable to domestic ceramics.Glass-ceramic is more at the waste that production process produces, and comprises that scrap products, work in-process repair the material of abandoning that hits and produce.Because the scrap glass pottery is different with the material of pottery and simple glass, there are differences on the composition, can not in the production of ceramic and simple glass product, add and utilize, can only reclaim back adding in glass-ceramic is produced and utilize.During conventional glass-ceramic was produced, the amount that adds the scrap glass pottery only accounted for about 10% of material quantity, is easy to cause product quality problem when add-on is big.Therefore, the generation of scrap glass pottery causes a large amount of scrap glass potteries to fail to be utilized greater than utilization, and is dropped and serious environment pollution, also causes the wasting of resources.
Summary of the invention
For overcoming above-mentioned deficiency, the invention provides and a kind ofly utilize glass-ceramic raw material that the scrap glass pottery makes and with the method for its production glass-ceramic product, can make scrap glass pottery add-on reach 40% of raw material total amount, and can guarantee the glass-ceramic constant product quality made, reach correlation standard, reduced that the scrap glass pottery is not utilized and the phenomenon that abandons prevents contaminate environment and causes the wasting of resources.
Glass-ceramic raw material of the present invention is made by following component: scrap glass pottery 40～50 weight parts, quartz sand 50～65 weight parts, soda ash 7～13 weight parts, aluminum oxide 4～7 weight parts, calcite 2～4 weight parts, Sodium Silicofluoride 2～5 weight parts, chloroazotic acid borax 6～9 weight parts, barium carbonate 1.5～3 weight parts, zinc oxide 3～5 weight parts, SODIUMNITRATE 0.2～1 weight part, Quilonum Retard 0.1～0.5 weight part, cerium oxide 0.1～0.5 weight part.
Glass-ceramic raw material of the present invention is preferably made by following component: scrap glass pottery 45 weight parts, quartz sand 58 weight parts, soda ash 10 weight parts, aluminum oxide 5.7 weight parts, calcite 3 weight parts, Sodium Silicofluoride 3.5 weight parts, chloroazotic acid borax 7.3 weight parts, barium carbonate 2.6 weight parts, zinc oxide 3.8 weight parts, SODIUMNITRATE 0.6 weight part, Quilonum Retard 0.3 weight part, cerium oxide 0.2 weight part.
Because glass-ceramic is fluorine-containing opaque glass, when joining the glass-ceramic raw materials for production, be easy to cause the glass-ceramic product to form crystal grain and make the product embrittlement and explosion, when the scrap glass pottery when the add-on of raw material surpasses 10%, grain formation more obvious.The contriver is by test, in raw material, strengthen the add-on of " boron " (chloroazotic acid borax), and other raw material adjusted accordingly, can reduce the formation of crystal grain in the product, reduce the coefficient of expansion simultaneously, the toughness of reinforcing glass matter, the heat-shock resistance of raising product, reach 40% o'clock of raw material total amount in scrap glass pottery add-on, product embrittlement can not occur yet.
Method with above-mentioned glass-ceramic raw material production glass-ceramic product comprises following production stage:
(1), will pulverize the scrap glass pottery of crossing 18 mesh sieves in the back and mix in proportion with other material, make the melting material;
(2), the melting material is dropped into from smelting furnace top, heated by electrodes to 1380 in stove～1450 ℃ become melting liquid, are delivered to mould from the discharge nozzle of smelting furnace bottom and carry out moulding, and the discharge nozzle temperature remains on 1150～1250 ℃;
The conventional material of making glass-ceramic is when melting, temperature generally remains on 1500～1550 ℃, because the scrap glass pottery relatively is easy to fusing, smelting temperature of the present invention can be reduced to 1380～1450 ℃, can be energy-conservation and shorten melting cycle, but the discharge nozzle of reply smelting furnace is incubated, and prevents to add the melting liquid premature set of scrap glass pottery; Described discharge nozzle can be to adopt electrothermal method to be incubated;
(3), mould in moulding process, temperature remains on 500～900 ℃;
The melting liquid that adds the scrap glass pottery is easy to solidify, and just solidifies when preventing that melting liquid is not paved with die surface, causes product size not meet, and need be incubated mould, reduces heat conduction and the thermosteresis of mould to melting liquid, prolongs the setting time of melting liquid; Described mould can be to adopt electrothermal method to be incubated in the bottom;
(4), after depanning, promptly enter tunnel furnace through the product of moulding and anneal, annealing time is 4～4.5 hours, annealing temperature is 250～580 ℃, makes product of the present invention;
, increase because add the internal stress of the product that the scrap glass pottery makes than conventional annealing time lengthening 1 hour through the annealing time of product in tunnel furnace of moulding, prolong annealing time, it is more abundant that the product internal stress is eliminated, and prevents product embrittlement.
Realize the present invention, can make the add-on of scrap glass pottery in raw material be up to 40%, reduce the glass-ceramic production cost of products, reduce environmental pollution simultaneously effectively, turn waste into wealth, the glass-ceramic raw material that makes satisfies the manufacturing technique requirent of glass-ceramic product.Use method production glass-ceramic product of the present invention, meet current energy-saving and cost-reducing theory, the constant product quality of production, milky white effective.
