(4) glass products
glass products according to different production processes have flat glass, glass blowing two categories. Currently, a large amount of flat glass, particularly through the plate glass deep processing, more suitable for the consumer market. Blown glass and other crafts made more three-dimensional modeling, classical furniture used in a variety of shapes more. Its characteristics: acid (fluorine acid outside) after alkali, oil, fire, steel resistant to 300 ℃.
4.1
plate glass plate glass is silicate raw materials, high temperature 1300 degree furnace melting into liquid, water flows through the surface of the molded tin, commonly known as float glass. As the raw material formulation, process parameters difference, green glass, white glass, colored glass three kinds of flat glass appearance carve. Flat glass manufacturing thinner (less than 3mm or less) the greater the difficulty, but too thick (more than 15mm) is also difficult, therefore, both the market this higher cost.
flat glass using a diamond (ie, ordinary glass cutter), high-speed water cutting, after cutting the sides of the glass can be milling process, such as grinding straight edge, bevel edge, round edge, duck lips, drilling, milling higher prices.
flat glass surface can be sanded (chemical, mechanical two kinds), silk screen painting, painting, engraving process, different surface treatment processes are not the same price, roughly sorted from highest to lowest: matte painting silk painting sculpture.
4.2 processing technology glass
here focus on its flat glass processing technology methods, in addition to the previously mentioned flat glass milling process outside, it can be bending, steel, and other bonding process, so that the "plane "to" three-dimensional "effect.
bending: refers to the plate glass begins to soften at about 500 ℃, mold lightly pressed that is required to achieve the deformation effect, inconsistent bending process in different plants and equipment, flat glass should be bending or edging sandblasting.
steel: refers to the glass at about 900 ℃ performed emergency cooling treatment. Its characteristics: no sharp broken glass, while the glass temperature resistance up to 300 ℃ not broken, its intensity is greatly improved by about 10 times.
bond: refers to the use of UV glue, curing by UV irradiation, the bonding glass can withstand more than 200kg after pulling adhesive material do Glass, glass and metal, but the process is different and glue to make a quality product .
above three processes to low cost price of processing methods: steel bending bonding.
4.3 Artistic glass processing
here focuses on the art of flat glass processing methods and results, attended to by definition "art" that has some artistic effect glass treatment.
matte effect: Flat glass used in mechanical scrub, scrub sand actual effect is too thick, easy hands marks, while the use of fluorine and other chemical matte which uses soaking syrup is made. The advantage is no coarse sand delicate hand, the process is combined with silk surface can make all kinds of patterns, text.
embossed effect: that is embossed using a mold of various patterns, designs, the use of glass to achieve bending deformation temperature, the pressure made by the machine. Currently many kinds of patterns, but also design their own system of molding, embossing glass quality is real pressure bending in a special column.
spray pattern: Spray effect there are two, one is the transparent color effects, and the other is opaque monochrome effect. Spraying inherently glass corrosion inhibitor plus color effects, it does not change the surface of the glass, it does not involve the nature of the glass structure.
paint effects: the glass surface paint treatment. In order to improve the adhesion of the paint, the glass should be painted into the oven dried, so as to achieve permanent adhesion effect.
DECORATED effect: a transparent film pattern printed up, and pasted to the glass surface, high temperature baking, carbide film, and patterns, text that is left on the surface.
