Description

A kind of black mat glass lampshade produced with new process

Technical field

The invention belongs to glass manufacturing area more particularly to it is a kind of produce using real estate quartz sand as raw material new process it is black Color mat glass lampshade.

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 black mat glass lampshade Manufacturing method, it is that carbon dust is added in dispensing by primary raw material of real estate quartz sand, then adds auxiliary material and mixed, melted Melt, black mat glass lampshade is made through being molded, annealing, after frosting, tempering again.The frosting technique prior art is to use frosting Liquid has operative employee's body injury because frosting liquor contains acid, and new frosting technique is to set what is gathered on the inner wall by blowing mold Age spot has become mat glass after glass lamp shade blow molding.Tempering must be carried out after black mat glass lamp shade forming, is made Tempering method is gas medium tempering method, and operating procedure is will to be molded black glass lampshade after cooling to be heated to close to it During 650~700 DEG C of softening temperature, its all part is blown simultaneously makes it cool down rapidly suddenly with cold wind, can increase after cooling The mechanical strength and thermal stability of black glass lampshade, basic demand is quickly and uniformly to cool down, equally distributed to obtain Stress.Glass lamp shade after tempering is compared with simple glass lampshade to be had the following advantages：1. intensity improves several times compared with simple glass； 2. safe to use, bearing capacity increase improves the frangible property of glass lamp shade, in the small broken of no acute angle destruction Piece；3. the glass resistance to thermal shocks matter after tempering can improve 3-5 times compared with simple glass, 220 degree or more can be generally born Difference variation.

Invention content：

Present invention mainly solves the problem of be to provide a kind of black mat glass lampshade produced with new process, what the present invention used Raw material is by weight ratio：Real estate quartz sand 62%-64%, sodium carbonate 10%-12%, carbon dust 1%, calcite 11%, aluminium hydroxide 10%th, sodium nitrate 1%, barium carbonate 1%, oxygen sodium metasilicate 0.7%, 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 dust, calcite, aluminium hydroxide, sodium nitrate, barium carbonate, oxygen silicic acid Sodium, anhydrous sodium sulphate, selenium powder, cobalt powder are sent into blender blending uniformly, and continuous induction melting furnace, power transmission after sealing are fed the mixture by conveyer Heating makes between the temperature of mixture reaches 1530 DEG C -1550 DEG C, to keep this temperature 23-25 hours, mixture is made to reach melting State obtains black glass molten mass；

（2）Black glass molten mass is sent into special frosting mold, black mat glass lampshade is made, by black mat glass lamp Cover is naturally cooling to be sent into annealing kiln with conveyer after 600 DEG C of hardening, and the time of 2-2.5 hours is passed through in annealing kiln, will be warm Degree is down to 150 DEG C from 600 DEG C, and annealing at this time finishes, and black mat glass lampshade is sent into air, in air natural cooling To room temperature；

（3）By after annealing black mat glass lampshade be sent into tempering case, first by black mat glass lampshade be heated to 660 DEG C- Between 680 DEG C, stop heating, be sent into cold wind from all directions immediately, after black mat glass lampshade is cooled to room temperature rapidly, Tempering terminates, and black mat glass lampshade from tempering case is taken out, obtains finished product.

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

The beneficial effects of the invention are as follows：Provide a kind of black mat glass lampshade produced with new process, this method tool There are the series of advantages such as simple for process, raw material sources are convenient, production cost is low, pollution-free, suitable industrialized production；Product is A kind of refined lampshade, with exquisite in workmanship, specious, smooth with dim sense, hardness height, stable chemical performance, surface The advantages that easy clean.
