Abstract
The utility model relates to a porous gas-generating propellant, which is characterized in that: the porous gas-generating propellant is a hollow cylinder shape, the external diameter of which is Phi 30mm to Phi 80mm, the internal diameter of which is Phi 4mm to Phi 8mm, the length of which is 10mm to 80mm, and the weight of which is 20 to 100g. The utility model has the advantages of large original combustion area, rapid averaged combustion speed, simple technology and being able to realize automatic production.
Description
Technical field
The utility model relates to a kind of multiple micro-porous gas production charge column, refers more particularly to a kind of multiple micro-porous gas production charge column that is used for the car safety air bag producer gas generator, belongs to the gas generating powder technical field.
Background technology
At present, how in the form of sheets or granular, diameter is about Φ 4mm～Φ 8mm to the gas generating powder that is used for car safety air bag pyrotechnic producer gas generator, the heavily about 50mg～200mg of each medicine grain, and the used gas generating powder 20g of body producer～250g whenever gets angry.So, when assembling, need the many gas generating powder grains of weighing to be assembled in the combustion chamber of producer gas generator, there is following shortcoming like this:
1. need many one weighing operations when assembling, and be not suitable for very much carrying out the automatic production line design;
Weighing and assembling process cycle longer, cause the gas generating powder moisture absorption easily, thereby have a strong impact on the use properties of producer gas generator;
3. the globule size of gas generating powder is difficult to accomplish highly unanimity on complete processing, causes the instability of combustionvelocity easily, thereby influences the performance of producer;
4. exist extruding and friction between the gas generating powder grain, in use cause fragmentation easily, thereby have a strong impact on the performance of producer.
Summary of the invention
The purpose of this utility model provides that big, the average combustionvelocity of a kind of initial combustion area is fast, technology simple, can realize the multiple micro-porous gas production charge column of automatic production.
For realizing above purpose, the technical solution of the utility model provides a kind of multiple micro-porous gas production charge column, it is characterized in that, described multiple micro-porous gas production charge column is a hollow cylindrical, its external diameter is Φ 30mm～Φ 80mm, and internal diameter is Φ 4mm～Φ 12mm, and long is 10mm～80mm, weight is 20g～100g, is provided with micropore in the multiple micro-porous gas production charge column.
The scantlings of the structure of described multiple micro-porous gas production charge column matches with the interior external diameter of producer mid point saucisson and producer.
The utility model changes sheet or granulous gas generating powder into gas production charge column, each powder column is a complete producer loaded constitution, the scantlings of the structure of gas production charge column matches with the interior external diameter of producer mid point saucisson and producer fully, each producer gas generator only needs to assemble a gas production charge column, this powder column relies on many ready-formed uniform micro to make it that bigger burning surface be arranged, thereby makes combustionvelocity also can reach the producer gas generator required standard.
The utility model has the advantages that big, the average combustionvelocity of initial combustion area is fast, technology simple, can realize automatic production.
Description of drawings
Fig. 1 is the multiple micro-porous gas production charge column structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be the multiple micro-porous gas production charge column structural representation, described multiple micro-porous gas production charge column 1 is a hollow cylindrical, its external diameter is Φ 52mm, and internal diameter is Φ 8mm, the long 20mm of powder column, weight is 38g, during preparation, multiple micro-porous gas production charge column 1 lining has been expired micropore 2, and the scantlings of the structure of multiple micro-porous gas production charge column 1 matches with the interior external diameter of producer mid point saucisson and producer.
During use,, very convenient as long as a multiple micro-porous gas production charge column 1 is put on the igniting pencil of producer gas generator.
