Problems solved by technology

[0005] The disadvantage of the above invention is that industrial production is very difficult. In the embodiment, only 15-20 parts by weight of attapulgite powder and 5-8 parts of refractory cement are added, and the particle strength of the spherical molecular sieve is difficult to reach the national standard. , and the attapulgite will lose its activity after being subjected to a high temperature above 550°C for 2 hours
[0007] The weak point of above-mentioned invention is, in the attapulgite clay desiccant special for hollow glass, contain the chloride of 10-20%, the chloride used in desiccant is calcium chloride mostly, although the hygroscopic rate of calcium chloride is higher High, but in the case of high air humidity, the desiccant is prone to deliquescence, which will corrode part of the structure of the insulating glass

Embodiment 1

[0023] Example 1: In the north of my country, the main purpose of using insulating glass is heating and heat preservation, and the stability of the desiccant is required to be better. When the temperature drops, there will be no condensation inside the insulating glass, and the moisture absorption rate is not required to be very high. High, the ingredients of the hollow glass mineral desiccant include the following components by weight percentage: attapulgite clay 65%, sodium hydroxide 3%, quicklime 25%, diatom 2% and high alumina 5%.

Embodiment 2

[0024] Embodiment 2: In the south of my country, the high temperature and high humidity throughout the year require the desiccant to have a higher moisture absorption rate. The ingredients of the hollow glass mineral desiccant include the following components by weight percentage: attapulgite clay 54%, sodium hydroxide 2%, quicklime 20%, diatomaceous earth 18% and high alumina 6%.

Abstract

The invention discloses a glazing glass mineral desiccant, the technique highlight of which is that, the glazing glass mineral desiccant comprises warp clay, sodium-hydroxide, calcium oxide, diatom earth, and high-alumina earth, and the product is prepared after milling, granulating, drying, sifting, and packing. It has a good stability, a high wet absorption ratio, and a strong intensity. And it can apply to glazing glass devices and other location needing to keep dry.

Description

Technical field: [0001] The invention relates to a desiccant, in particular to a hollow glass mineral desiccant. Background technique: [0002] Insulating glass is an energy-saving building material product under the current energy shortage situation, and its application has a broad space. The speed of energy development in our country is far behind the speed of economic development. If we vigorously promote energy-saving buildings, we can reduce the number of power plants built every year in the country, reduce the energy consumption of the inner and outer walls of buildings, and improve the heat insulation of building doors, windows, and inner and outer walls. 1. Air tightness is an urgent problem we face, which provides a basis for the development and promotion of insulating glass products. [0003] The energy-saving performance of insulating glass is realized by a dry and sealed air layer. The purpose of using a desiccant in the insulating glass is to keep the inner cav...
