Abstract
The invention discloses a preparation method of an oxygen-enriched ceramic composite material for a chemical oxygen firefighting self-rescue respirator. The method is characterized by comprising the following steps of: 1) uniformly mixing the fired medium-white mud bisque and palladium chloride at a weight ratio of 10,000:1 to obtain slurry; 2) dehydrating the slurry to obtain particles with particle sizes of 80-120mm; 3) firing the obtained particles at a high temperature of 1,260-1,340 DEG C to obtain oxygen-enriched ceramic; and 4) mixing potassium superoxide and the oxygen-enriched ceramic at a mass ratio of 2:1 to obtain the oxygen-enriched ceramic composite material. Through the novel material disclosed by the invention, palladium chloride has the functions of a catalyst and accelerates the production of oxygen; the potassium superoxide is mixed with the ceramic to prevent caking; the ceramic with many micropores can adsorb water vapor to further increase the reaction rate; and moreover, the reaction temperature is low, and the heat dissipation speed is high.
Description
Technical field
The present invention relates to a kind of method of raw oxygen of chemical oxygen firefighting self-rescue apparatus, particularly relate to a kind of preparation method of the oxygen enrichment ceramic composite for chemical oxygen firefighting self-rescue apparatus.
Background technology
Chemical oxygen firefighting self-rescuer usually in public presence of fire or plate indicates nature of danger time use, such as hotel, public place of entertainment, mine, organizational equipment etc., the process that current chemical oxygen firefighting self-rescuer generates oxygen is all reacted by potassium superoxide and carbonic acid gas and water, in reaction process, potassium superoxide easily lumps, cause generating oxygen rates after caking to reduce, affect eupnea, and this reaction produces a large amount of heats, the highest incoming call air that makes reaches degree more than 50, air-breathing has burning sensation, and user is very uncomfortable.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of the oxygen enrichment ceramic composite for chemical oxygen firefighting self-rescue apparatus, the product oxygen material obtained by the method does not lump, can effective reaction speed, and in reaction process, heat production is few, breathing temperature is low, uses rationally comfortable.
The present invention is achieved like this, and square method steps is:
1) in burning till rear middle white clay bique weight, the weight of Palladous chloride prepares burden in the ratio of 10000:1, and blendes together mud equably;
2) slurry dewatering is made the particle of particle diameter 80-120mm;
3) particle made is fired 6 hours one-tenth oxygen enrichment potteries with the elevated-temperature seal of 1260-1340 degree;
4) ratio of potassium superoxide and the ceramic 2:1 in mass ratio of oxygen enrichment is mixed and obtains oxygen enrichment ceramic composite.
The particle diameter 4-8mm of described potassium superoxide.
Usage and duration of service: static duration of service is 400 grams of oxygen enrichment ceramic composites per hour.
Precaution
1. forbid contacting woodwork.
2, forbid that contact combustible and explosive articles loads in mixture.
3, production process keeps health.Drying, avoids vibrations, notes labour protection.
4, deposit and transport should keep dry lucifuge, shock-absorbing, keep away high temperature, good seal.
Technique effect of the present invention is: utilize this type material, and Palladous chloride has the function of catalyzer, accelerates to produce oxygen, and potassium superoxide and pottery used in combination, do not lump, pottery has many minute apertures to adhere to steam, more impel quickening speed of reaction, temperature of reaction is low, rapid heat dissipation.
