Description

A kind of manufacturing method of glass lamp shade

Technical field

The invention belongs to glass manufacturing area more particularly to a kind of sides that glass lamp shade is manufactured using real estate quartz sand as raw material Method.

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 manufacturer of glass lamp shade Method, it is using real estate quartz sand as primary raw material, is mixed, melted, again through being molded, annealing, made after tempering in addition auxiliary material Obtain glass lamp shade.Glass lamp shade molding after must carry out tempering, the tempering method used be gas medium tempering method, operating procedure It is when will be molded glass lamp shade after cooling to be heated to close to 650~700 DEG C of its softening temperature, suddenly to its all part simultaneously Blow makes it cool down rapidly with cold wind, can increase the mechanical strength and thermal stability of glass lamp shade after cooling, and basic demand is fast Speed and equably cool down, to obtain equally distributed stress.Glass lamp shade after tempering has been compared as follows with simple glass lampshade Advantage：1. intensity improves several times compared with simple glass；2. safe to use, bearing capacity increase improves the easy of glass lamp shade Fragility matter, in the fractionlet of no acute angle destruction；3. the glass resistance to thermal shocks matter after tempering can compared with simple glass 3-5 times is improved, can generally bear 220 degree or more of 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 glass lamp shade Method, the raw material that uses of the present invention is by weight ratio：Real estate quartz sand 62%-64%, sodium carbonate 10%-12%, calcite 11%th, aluminium hydroxide 10%, sodium nitrate 2%, 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, calcite, aluminium hydroxide, sodium nitrate, barium carbonate, oxygen sodium metasilicate, member Bright powder, selenium powder, cobalt powder are sent into blender blending uniformly, and continuous induction melting furnace is fed the mixture by conveyer, and power transmission heats after sealing, Make between the temperature of mixture reaches 1530 DEG C -1550 DEG C, to keep this temperature 23-25 hours, mixture is made to reach molten condition, Obtain glass melt；

（2）Glass melt is sent into mold, glass lamp shade is made, glass lamp shade is naturally cooling to after 600 DEG C of hardening with defeated Machine is sent to be sent into annealing kiln, the time of 2-2.5 hours is passed through in annealing kiln, temperature is down to 150 DEG C from 600 DEG C, is annealed at this time It finishes, glass lamp shade is sent into air, naturally cools to room temperature in air；

（3）Glass lamp shade after annealing is sent into tempering case, between glass lamp shade first is heated to 660 DEG C -680 DEG C, stop plus Heat is sent into cold wind from all directions immediately, and after glass lamp shade is cooled to room temperature rapidly, tempering terminates, by glass lamp shade from steel Change and taken out in case, obtain finished product.

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 glass lamp shade is provided, this method has simple for process, former The series of advantages such as material source is convenient, production cost is low, pollution-free, suitable industrialized production；Product is a kind of refined lamp Cover has many advantages, such as that exquisite in workmanship, specious, hardness is high, stable chemical performance, surface are smooth easy clean.
