CN1331058A - Process for preparing microcrystal glass from wind-laid sand in desert - Google Patents

Abstract

A microcrystal glass is prepared from the wind-laid sand in desert (about 80%), CaCO3 (3-5%), MgO (2-3%), NaCO3 (4-6%), crystallized metal powder (3-5%) and pigment (1-2%) through smelting, quenching in water, crystallizing, and float technology. Its advantage includes wide range of raw materials.

Description

Use preparing microcrystal glass from wind-laid sand in desert

The invention belongs to the material of construction production technical field, specifically is to produce sheet glass with the desert drift-sand.

Building microcrystalline glass sheet material still is confined to casting, calendering and sintering process production method both at home and abroad at present, and small scale yields poorly, the cost height.Invented float glass process devitrified glass board production technology recently, product has had good homogeneity, planeness and surface flatness, has saved follow-up sheet material shaping, grinding and polishing process simultaneously, improves the finished product rate greatly, reduced production cost, and can large-scale industrialized production.

Goal of the invention of the present invention provides a kind of preparing microcrystal glass from wind-laid sand in desert of using, and adopting the desert drift-sand is main raw material, and float glass process is produced microcrystal glass plate, expands the raw material source of producing devitrified glass greatly, has reduced production cost; Turn waste into wealth simultaneously, turn bane into boon, utilization is initiatively changed into by passive improvement in the desert.

The present invention is to be main raw material with the desert drift-sand.The weight percent of concrete composition of raw materials is: drift-sand: about 80%, CaCO ₃: 3---5%, MgO:2-3%, NaCO ₃: 4-6%, and add various crystal metal powder 3-5% according to different varieties, produce and do not take charge of color and add all kinds of chemical industry colorants 1-2%.Found → shrend → crystallization → rubbing down → finished product float glass process production technique production microcrystal glass plate by batching.

Adopting immense desert drift-sand is the high-quality microcrystal glass plate of main material production, get without cease arranged, with intact raw material source, the starting material of present production microcrystal glass plate have been expanded greatly, reduced production cost, turned waste into wealth simultaneously, turned bane into boon, for the mankind utilization initiatively being changed into by passive improvement in the desert provides new thinking and approach, has remarkable economical, society and ecological benefits.

Embodiment 1: use the desert drift-sand: CaCO 80%, ₃: NaCO 4%, ₃: 10%, the manganese ore powder: 3-5%, zirconium: 1-2% can produce red devitrified glass, and color is by what of the add-on of manganese ore powder, can be by light red, pink, flesh-coloured, purplish red, brown look product from shallow to deep such as red.

Embodiment 2: drift-sand: 75%, and MgO:8%, NaCO ₃: 9%, copper ore powder: 4-8%, zinc powder 1-3% can be produced the green-series product, pale green, yellowish green, grass green, dark green, blackish green etc.

Claims (2)

1, uses preparing microcrystal glass from wind-laid sand in desert, it is characterized in that with the desert drift-sand be main raw material, adopt float glass process to produce microcrystal glass plate.

2, the preparing microcrystal glass from wind-laid sand in desert of using as claimed in claim 1 is characterized in that the weight percent of composition of raw materials is: drift-sand: about 80%, CaCO ₃: 3---5%, MgO:2-3%, NaCO ₃: 4-6%, and add various crystal metal powder 3-5% according to different varieties, produce different colours and add all kinds of chemical industry colorants 1-2%.
