Abstract

The invention belongs to cyclic utilization of wastes in the field of materials, belongs to the technical field of circular economy, and particularly relates to regeneration and cyclic utilization of a waste ceramics gypsum mold. According to fabrication of beer bottle glass by using the waste ceramics gypsum mold, the production cost of the beer bottle glass is reduced when resource regeneration and circulation are achieved. The fabrication of the beer bottle glass is a method for cleaning the waste ceramics gypsum mold, adding silica sand (containing 5%-6% of aluminium oxide), sandstone, limestone, dolomite, sodium carbonate and a little of chrome ore powder, and firing the beer bottle glass by virtue of a high-temperature melting method. Due to the characteristics that the waste ceramics gypsum mold contains calcium sulfate and sodium bicarbonate, the calcium sulfate and the sodium bicarbonate are taken as clarifying agents in the glass melting process, and a technique of using the waste ceramics gypsum mold as an unnecessary raw material, adding a few of main raw materials such as silica sand, sandstone and the like, and preparing a beer bottle glass product by virtue of a melting method is developed. The adding amount of the waste ceramics gypsum mold in the beer bottle glass formula reaches 4%-5%.

Description

Waste ceramic plaster mould manufactures beer bottle glass

Technical field

This invention belongs to resource recovery recycle; be exactly that the plaster mould utilizing pot bank discarded passes through cleaning, pulverizes specifically, add to by a certain percentage in frit, manufacture beer bottle glass goods; both protect environment, again reduce the production cost of Beer Bottle.

Background technology

No matter daily water-consumption forecasting is injection forming or compression moulding, and its mould is all adopt plaster of Paris material to be made, and after using after a while, these plaster moulds will go out of use, and pile up like a mountain for the plaster mould gone out of use in a large number.The main chemical compositions of gypsum is calcium sulfate, not only takies a large amount of places, and severe contamination water resources.Therefore the recycle of gypsum is very important.The present invention mainly utilizes discarded plaster mould as the necessary raw material of Beer Bottle, adds the raw materials such as quartz sand, feldspar, calcite, soda ash and chromite ore fine, produces cheap beer bottle glass, not only reduces production cost, and also utilization of waste material protects environment.

Summary of the invention

1, the object of invention: the present invention makes discarded plaster mould reach resource recovery, protection of the environment, reduces floor space, and containing calcium sulfate in simultaneously discarded plaster mould, these compositions of sodium bicarbonate, they are the finingss in glass fusion process.Discarded plaster mould, through simple processing, is used in Beer Bottle production, greatly can reduces production cost.

2, detailed description of the present invention: by discarded plaster mould through cleaning (ceramic mud on plaster mould, pug are cleaned up), be crushed to 80 orders, mix by a certain percentage with the raw material such as silica sand, sandstone, Wingdale, soda ash and chromite ore fine, carry out high temperature melting, homogenizing, clarification, shaping, annealing makes beer bottle glass.Through repetition test, obtain and utilize discarded plaster mould to manufacture the optimization of C/C composites of beer bottle glass goods, and determine process system.

Raw material consists of:

Silica sand 28 ~ 30%(salic 5 ~ 6%), sandstone 30 ~ 32%, Wingdale 3 ~ 5%, rhombspar 7 ~ 9%, soda ash 25 ~ 27%, gypsum 4 ~ 5%, chromite ore fine is lower than 0.2%.

Technological process is:

Discarded plaster mould cleaning → drying → material side calculating → weighing → Homogeneous phase mixing → fusing → homogenizing → clarification → shaping → annealing → inspection → packaging

The temperature of fusion of glass is at 1430 ~ 1450 DEG C.

The annealing temperature of goods is at 540 ~ 560 DEG C.

Purposes: the present invention utilizes discarded plaster mould to manufacture a kind of technology of beer bottle glass goods.

3, useful effect: innovation of the present invention utilizes discarded plaster mould to manufacture beer bottle glass goods, reduces the production cost of beer bottle glass goods, saved resource, protects environment.

Embodiment

Discarded plaster mould is carried out clean (ceramic mud on plaster mould, pug are cleaned up), add and join some mineral as silica sand, sandstone, Wingdale, rhombspar, soda ash and a small amount of chromite ore fine.Beer bottle glass goods are obtained by Homogeneous phase mixing, fusing, homogenizing, clarification, shaping, annealing process.

Various raw material granularity controls below 80 orders.Glass cullet size controls below 2 centimetres, and the object of mixing is mixed by various raw material, and temperature of fusion is at 1430 ~ 1450 DEG C, and flame radiaton temperature is at 1530 ~ 1550 DEG C.Glass melting kiln can adopt the glass furnace such as flame furnace, electric furnace, and homogenizing and clarification complete in melting process, realizes glass metal homogenizing and clarification by Timing, shapingly adopts blow-and-blow technique, according to the product determination moulding process produced.Annealing carries out in lehr, and annealing temperature is 540 ~ 560 DEG C, and annealing time is 30 minutes.

Claims
