Abstract
The invention discloses a molecular sieve for hollow glass and a preparation method thereof. The preparation method is mainly that composition materials of calcium bicarbonate, sodium base bentonite, sodium carbonate and sodium silicate are stirred and mixed by weight, the composition materials are prilled, tanning agent myrica is added, particle polishing treatment is carried out, and then the composition materials are put in a roasting furnace for firing. The composition materials are detected, separated and screened for packaging. The preparation method of the molecular sieve is simple, low in raw material cost and capable of effectively adopting moisture and impurities in an air layer of the hollow glass, keeping and stabilizing the low dew point in the hollow glass and prolonging service life of the hollow glass.
Description
Technical field
The present invention relates to a kind of double glazing with molecular sieve and preparation method thereof, belong to glass manufacturing area.
Background technology
The main fractionated molecule sieve of the siccative that double glazing is used and silica gel, molecular sieve is silicon and the synthetic crystalline microporous material of aluminum oxide, is divided into category-A and X class.
The double glazing molecular sieve can adsorb moisture and the residual organic matter in the double glazing simultaneously, even make double glazing still keep clear transparent under the low temperature very much, it is poor fully to reduce simultaneously the powerful external and internal pressure that double glazing bears because of the great variety of season and day and night temperature, the double glazing molecular sieve has also solved double glazing and has expanded or shrink and the broken problem of distortion that causes, prolongs the work-ing life of double glazing.
Summary of the invention
In order to alleviate the deficiencies in the prior art and defective, the object of the present invention is to provide a kind of double glazing molecular sieve and preparation method thereof, preparation method of the present invention is simple, raw materials cost is cheap, moisture and the foreign material that can effectively adsorb the double glazing gas cloud, keep and stable double glazing in low dew point, prolonged work-ing life of double glazing.
The present invention adopts following technical scheme to achieve these goals:
The double glazing molecular sieve is characterized in that the weight part of its constitutive material is: Calcium hydrogen carbonate 50-60%, sodium base bentonite 28-32%, yellow soda ash 4-6%, water glass 4-6% and myrica extract 4-6%.
Described double glazing molecular sieve is characterized in that the weight part of its constitutive material is: Calcium hydrogen carbonate 55%, sodium base bentonite 30%, yellow soda ash 5%, water glass 5% and myrica extract 5%.
The described double glazing preparation method of molecular sieve is characterized in that may further comprise the steps:
(1) weight part by constitutive material takes by weighing each component raw material, then Calcium hydrogen carbonate, sodium base bentonite, yellow soda ash and water glass are added and mix when beginning in the unit to be stirred to 15-20 minute, stir water spray simultaneously, make its raw material moisture content about 30%, pulverize again;
(2) tablets press begins raw material is further processed, and makes it become particulate state, and diameter is 0.6-3.0mm, after the particle diameter of product begins to take shape, adds myrica extract, carries out particle polishing and handles 8-12 minute formation preliminary product;
(3) first portion product is dropped in the stoving oven, carry out the processing of product subordinate phase, in the process of baking, the control temperature to high temperature 680-720 ℃, kept sintering by the end temperature 2.8-3.2 hour;
(4) detect separation and screening, pack then, packaging temp is controlled at 95-105 ℃.
Beneficial effect of the present invention:
Preparation method of the present invention is simple, and raw materials cost is cheap, can effectively adsorb moisture and the foreign material of double glazing gas cloud, keep and stable double glazing in low dew point, prolonged work-ing life of double glazing.
