Description

A kind of manufacturing method of black elen shade

Technical field

The invention belongs to glass manufacturing areas more particularly to one kind to manufacture black ground glass by raw material of real estate quartz sand The method of 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 elen shade 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, again through being molded, annealing, frosted, frosted black glass lampshade is made after tempering.The distinguishing feature that lampshade is presented after frosted It is surface exquisiteness, light transmission is opaque, there is dim sense, is compared in addition to transparency with former base glass on capability and performance, other performances It is constant.Black elen shade molding after must carry out tempering, the tempering method used be gas medium tempering method, operative employee Skill is when will be molded black glass lampshade after cooling to be heated to close to 650~700 DEG C of its softening temperature, suddenly to its all portion Divide to blow simultaneously makes it cool down rapidly with cold wind, can increase the mechanical strength and thermal stability of black glass lampshade, base after cooling This requirement is quickly and uniformly to cool down, to obtain equally distributed stress.Glass lamp shade and simple glass lampshade after tempering Compared to having the following advantages：1. intensity improves several times compared with simple glass；2. safe to use, bearing capacity increase improves glass The frangible property of glass lampshade, in the fractionlet of no acute angle destruction；3. glass resistance to thermal shocks matter after tempering compared with Simple glass can improve 3-5 times, 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 the production black frosted of main primary industry metaplasia The method of glass lamp shade, the raw material that the present invention uses are by weight ratio：Real estate quartz sand 62%-64%, sodium carbonate 10%-12%, Carbon dust 1%, calcite 11%, aluminium hydroxide 10%, sodium nitrate 1%, barium carbonate 1%, oxygen sodium metasilicate 0.7%, anhydrous sodium sulphate 0.3%, selenium powder 0.9%th, cobalt powder 0.1%.

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