A kind of mm granules of the present invention is uniformly distributed with and the magnetosensitive elastomer production device of catenation, and it comprises: base, L type side plate, screw, down small front apron, go up small front apron and circular hole slab; Position annexation between them is: base is put on the ground, and its upper surface is connected through screw with L type side plate lower surface; Following small front apron places the base upper surface, and its side and L type side plate are bonding through double faced adhesive tape; The lower surface of last small front apron places down the upper surface of small front apron; So repeatedly, small front apron on each is stacked layer by layer; When putting particle position, circular hole slab places the upper end of small front apron.
Said base is that the square-section is dull and stereotyped, is the support component of device, and it selects for use mild carbon steel or common iron to make;
Said L type side plate, profile is the L type, is the side shield and the skeleton of device, and it selects for use mild carbon steel or common iron to make;
Said small front apron down is a rectangle steel, and it is the baffle plate of first encapsulating, is used for obturator, and it selects for use mild carbon steel or common iron to make;
Said upward small front apron is a rectangle steel, and it is the baffle plate of every layer of encapsulating, and is used for airtight colloid, and it selects for use mild carbon steel or common iron to make;
Said circular hole slab is the rectangular thin plate of band locating slot and circular hole, is used for confirming particle in the position of magnetosensitive elastic body, and it selects for use mild carbon steel or common iron to make.
Wherein, the aperture on the circular hole slab is 2 to 8 millimeters; The quantity in hole is 9 to 144.
Workflow of the present invention is following:
At first, base and L type side plate are connected through screw.Then, utilize common adhesive (like double faced adhesive tape), will descend small front apron and base upper surface and L type side plate side bonding firmly.Secondly, pour into the matrix glue of certain volume, the height of colloid can not surpass the height of small front apron down.Once more, utilize double faced adhesive tape, will go up small front apron and be bonded in down small front apron upper end and side plate side.After treating the matrix adhesive curing, pour into the colloid of a little volume again.Place on it and can not sink the time, circular hole slab is placed on the upper end of small front apron, and utilizes circular hole slab to put one deck particle when the degree of solidifying of the colloid that newly pours into can make ferromagnetic particle.This preparation facilities is placed ventilation a period of time.When particle keeps static in colloid, remove circular hole slab.Repeat above-mentioned steps, after accomplishing the test specimen making, the demoulding.
3, a kind of mm granules of the present invention is uniformly distributed with and the magnetosensitive elastomer production device of catenation, is characterized in:
1. this preparation facilities can make the interior millimeter of a magnetosensitive elastic body test specimen grade particles realize that complete ideal uniform or chain distribute.
2. this preparation facilities is simple to operate, and compact conformation is economical and practical, and volume is little.
