Description

A kind of manufacturing method of green glass lampshade

Technical field

The invention belongs to glass manufacturing areas more particularly to one kind to manufacture green glass lampshade by raw material of real estate quartz sand 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 system of green glass lampshade Method is made, it is to add the green cullet of purchase in dispensing as primary raw material using real estate quartz sand, then add auxiliary material and mixed It closes, melting, green glass lampshade be made through being molded, annealing, after tempering again.Tempering must be carried out after green glass lamp shade forming, The tempering method used be gas medium tempering method, operating procedure be will be molded glass lamp shade after cooling be heated to it is soft close to its When changing 650~700 DEG C of temperature, its all part is blown simultaneously makes it cool down rapidly suddenly with cold wind, can increase glass after cooling The mechanical strength and thermal stability of glass lampshade, basic demand are quickly and uniformly to cool down, to obtain equally distributed stress.Steel Glass lamp shade after change is compared with simple glass lampshade to be had the following advantages：1. intensity improves several times compared with simple glass；2. it uses Safety, bearing capacity increase, and improve the frangible property of glass lamp shade, in the fractionlet of no acute angle destruction；3. steel Glass resistance to thermal shocks matter after change can improve 3-5 times compared with simple glass, can generally bear 220 degree or more of the temperature difference and become Change.

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 green glass The method of lampshade, the raw material that the present invention uses are by weight ratio：Real estate quartz sand 32%-34%, sodium carbonate 10%-12%, purchase Green cullet 30%, calcite 11%, aluminium hydroxide 10%, sodium nitrate 2%, barium carbonate 1%, oxygen sodium metasilicate 0.7%, anhydrous sodium sulphate 0.3%th, selenium powder 0.9%, cobalt powder 0.1%.
