A kind of self-propagating reaction-based ignition packaging head and packaging method thereof

Abstract

The invention relates to the technical field of a packaging powder head and specifically relates to an igniting packaging powder head based on self-propagating reaction and a packaging method thereof. The powder A and powder B are respectively prepared according to different formulas, and then different adhesives are added for converting powder A and powder B into muddy form and are plugged into a container opening, the powder is pressed under the condition of full sealing container and the shaking layering is avoided. In an igniting process, the packaging powder head is ignited by the igniting device, an igniting powder head is ignited by the packaging powder head, the main powder in the container is ignited by the igniting powder head, the opening space is above the main powder and the packaging powder head and the igniting powder head are burned out, so that the explosion is avoided. The igniting packaging powder head based on self-propagating reaction can solve the packaging problem of self-propagating technique in the industrialization and has a certain promoting effect on the industrialization of the self-propagating technique.

Description

technical field [0001] The invention relates to the technical field of packaged drug heads, in particular to a self-propagating reaction-based ignited packaged drug head and a packaging method thereof. Background technique [0002] Self-propagation high-temperature synthesis (SHS for short), also known as combustion synthesis (combustion synthesis) technology, uses the self-heating and self-conduction of high chemical reaction heat between reactants to synthesize materials A technology, once the reactant is ignited, it will automatically spread to the unreacted area until the reaction is complete. It is a new method for preparing high-temperature inorganic compound materials. Due to the unique advantages of this method, it has been more and more applied in the fields of welding, new material preparation, and new energy. [0003] Although self-propagating technology has been widely used, it is rarely made into a complete product. When using self-propagating technology, most ...

AI Technical Summary

Problems solved by technology

[0003] Although self-propagating technology has been widely used, it is rarely made into a complete product. When using self-propagating technology, most of the researchers will configure bulk powder on site according to the formula and ignite it with a fuse. To a large extent Limits the industrial development of self-propagating technology

[0004] The above phenomenon is related to the characteristics of the self-propagating reaction: 1. The self-propagating powder cannot be tightly sealed: a large amount of heat and gas will be generated when the self-propagating reaction occurs. If a tight seal (similar to the packaging of drug capsules in daily life) 2. The self-propagating powder must be tightly sealed: if the self-propagating powder is not tightly sealed, it is only put into the container and then sealed, the internal A cavity is left (similar to the packaging method of mineral water in daily life), which will lead to stratification of components with different specific gravity during transportation, and the powder will fail after stratification
