Description

A kind of manufacturing method of blackish green glass lamp shade

Technical field

The invention belongs to glass manufacturing areas more particularly to one kind to manufacture blackish green Glass lamp by raw material of real estate quartz sand The method of cover.

Background technology

Glass is a kind of transparent or semitransparent solid matter, the formation contiguous network structure in melting, in cooling procedure Viscosity gradually increases and hardens and non crystallized silicates nonmetallic materials.It using quartz sand, soda ash is main that simple glass, which is, Raw material, through 1500 DEG C -1600 DEG C of high-temperature fusion, molding and amorphous non-crystalline solid material prepared by through being quickly cooled down, Wherein dioxide-containing silica is between 55%-65%, the calcium oxide also containing 15% sodium oxide molybdena and 10%, its main feature is that hard texture and It is crisp, water white transparency, low production cost, easily molded.Glass can be made different shapes and have different purposes, Glass lamp Cover is one kind of glassware, it is after the working process of surface to obtain finished product after tempering again using glass as basic material, Feature is that hardness height, stable chemical performance, surface are smooth easy clean, environmentally friendly.It is different to be made that different materials can also be added Color, can be by putting-out system into frosted, frosting, applique colour etc..Product of the present invention is a kind of blackish green glass lamp shade Manufacturing method, it is to add carbon black and the green cullet of purchase in dispensing as primary raw material using real estate quartz sand, then add auxiliary Material is mixed, is melted, green glass lampshade is made through being molded, annealing, after tempering again.It is necessary after the molding of blackish green glass lamp shade Tempering is carried out, the tempering method used is gas medium tempering method, and operating procedure is will to be molded glass lamp shade heating after cooling During to close to 650~700 DEG C of its softening temperature, its all part is blown simultaneously makes it cool down rapidly suddenly with cold wind, after cooling The mechanical strength and thermal stability of glass lamp shade can be increased, basic demand is quickly and uniformly to cool down, and is uniformly divided to obtain The stress of cloth.Glass lamp shade after tempering is compared with simple glass lampshade to be had the following advantages：1. intensity is improved compared with simple glass Several times；2. safe to use, bearing capacity increase improves the frangible property of glass lamp shade, in no acute angle destruction Fractionlet；3. the glass resistance to thermal shocks matter after tempering can improve 3-5 times compared with simple glass, can generally bear 220 degree with On difference variation.

Invention content：

Present invention mainly solves the problem of be to provide it is a kind of using this real estate quartz sand for main primary industry metaplasia production blackish green glass The method of glass lampshade, the raw material that the present invention uses are by weight ratio：Real estate quartz sand 47%-49%, sodium carbonate 10%-12%, charcoal Black 0.5%, green cullet 15%, calcite 10.5%, aluminium hydroxide 10%, sodium nitrate 2%, barium carbonate 1%, oxygen sodium metasilicate are purchased 0.7%th, anhydrous sodium sulphate 0.3%, selenium powder 0.9%, cobalt powder 0.1%.

The present invention can be achieved through the following technical solutions：

（1）By the real estate quartz sand of formula ratio, sodium carbonate, carbon black, the green cullet of purchase, calcite, aluminium hydroxide, nitric acid Sodium, barium carbonate, oxygen sodium metasilicate, anhydrous sodium sulphate, selenium powder, cobalt powder are sent into blender blending uniformly, are fed the mixture by conveyer Continuous induction melting furnace, power transmission heats after sealing, makes between the temperature of mixture reaches 1530 DEG C -1550 DEG C, to keep this temperature 23-25 small When, mixture is made to reach molten condition, obtains blackish green glass melt；

（2）Blackish green glass melt is sent into mold, blackish green glass lamp shade is made, by blackish green glass lamp shade Temperature fall Annealing kiln is sent into conveyer after to 600 DEG C of hardening, the time of 2-2.5 hours is passed through in annealing kiln, temperature is dropped from 600 DEG C To 150 DEG C, annealing at this time finishes, and blackish green glass lamp shade is sent into air, naturally cools to room temperature in air；

（3）Blackish green glass lamp shade after annealing is sent into tempering case, blackish green glass lamp shade is first heated to 660 DEG C -680 DEG C Between, stop heating, be sent into cold wind, after blackish green glass lamp shade is cooled to room temperature rapidly, tempering knot from all directions immediately Blackish green glass lamp shade from tempering case is taken out, obtains finished product by beam.

Above-mentioned steps（1）Described in continuous induction melting furnace electric smelter.

The beneficial effects of the invention are as follows：A kind of manufacturing method of blackish green glass lamp shade is provided, this method has technique The series of advantages such as simply, raw material sources are convenient, production cost is low, pollution-free, suitable industrialized production；Product is a kind of essence The lampshade of system has many advantages, such as that exquisite in workmanship, specious, hardness is high, stable chemical performance, surface are smooth easy clean.
