Abstract
A dried-powder fire-extinguishing agent of ammonium phosphate is prepared from ammonium dihydrogen phosphate (50-76 Wt. portions), white carbon black (1.2-2.4), and silicon powder (22.6-48.2) through mixing, drying, addition of mixture liquid of silicon oil and toluene, and siliconizing, and features high floability, 0.05% of water content and penetration rate of over 22 mm.
Description
The present invention relates to the preparation method of fire-extinguishing chemical, is mainly used in the production method of the multi-functional dry powder extinguishing chemical of ammonium phosphate salt.
The process of the batch mixing of the ammonium phosphate powder extinguishing agent of domestic production at present, drying, silication, be respectively to carry out separately in retort, and it is unreasonable to fill a prescription, therefore the product moisture content index of making is higher, agglomeration resistance ability etc. have influenced the performance of extinguishing chemical.
Purpose of the present invention is exactly at the problems referred to above, and a kind of preparation method with fine resistive connection ability, ammonium phosphate powder extinguishing agent that moisture content is lower is provided.
The object of the present invention is achieved like this: the 50-75 part ammonium dihydrogen phosphate (ADP) after the present invention learns from else's experience at first by weight and pulverizes, 1.2-2.4 part white carbon are packed into the silica flour of 22.6-48.2 part in the dry silication jar, after the batch mixing drying, after the silicone oil-toluene mixture liquid of adding capacity, the silication.
Major advantage of the present invention:
White carbon black can prevent that ammonium dihydrogen phosphate (ADP) from adhering to machine in crushing process, also has good repellency and reinforcement in addition; Silica flour is a kind of porous lyophobic dust, plays the mechanical isolation effect in powder extinguishing agent, prevents to form salt bridge between the inorganic salts particulate, reduces dry powder particle frictional resistance at the volley, increases the mechanical flow of product greatly; And ammonium dihydrogen phosphate (ADP), white carbon black, silica flour fully mix, react in same dry silication jar, and its moisture content can reach 0.05%, and needle penetration is more than 22 millimeters.
Concrete method for making of the present invention is as follows:
After getting the material pulverizing of 50-75 part ammonium dihydrogen phosphate (ADP), 1.2-2.4 part white carbon at first by weight, stirring cage by material transfer delivers in the dry silication jar, add 22.6-48.2 part silica flour simultaneously, dry one hour of batch mixing, after 103 ℃ of the temperature, silicone oil-the toluene mixture liquid (common process) that adds capacity, silication discharging in 1 hour are sieved.
Embodiment 1:
Get 350 kilograms of ammonium dihydrogen phosphate (ADP)s, 10 kilograms of white carbon blacks, 90 kilograms of silica flours by weight.
Embodiment 2:
Get 225 kilograms of ammonium dihydrogen phosphate (ADP)s, 8 kilograms of white carbon blacks, 217 kilograms of silica flours by weight.
Embodiment 3:
Get 270 kilograms of ammonium dihydrogen phosphate (ADP)s, 8 kilograms of white carbon blacks, 172 kilograms of silica flours by weight.
Claims (4)
1. the preparation method of ammonium phosphate powder extinguishing agent, learn from else's experience at first by weight 50-75 part ammonium dihydrogen phosphate (ADP) after pulverizing, 1.2-2.4 part white carbon packed in the dry silication jar with 22.6-48.2 part silica flour, after the batch mixing drying, after the silicone oil-toluene mixture liquid of adding capacity, the silication.
2. ammonium phosphate powder extinguishing agent according to claim 1 is characterized in that getting by weight 350 kilograms of ammonium dihydrogen phosphate (ADP)s, 10 kilograms of white carbons, 90 kilograms of silica flours.
3. ammonium phosphate powder extinguishing agent according to claim 1 is characterized in that getting by weight 225 kilograms of ammonium dihydrogen phosphate (ADP)s, 8 kilograms of white carbon blacks, 217 kilograms of silica flours.
4. ammonium phosphate powder extinguishing agent according to claim 1 is characterized in that getting by weight 270 kilograms of ammonium dihydrogen phosphate (ADP)s, 8 kilograms of white carbon blacks, 172 kilograms of silica flours.
