Abstract

The present invention is a kind of preparation method of ammonium phosphate powder extinguishing agent.It is characterized in that producing: get phosphoric acid by wet process one ammonium 300-900, calcium carbonate 30-450, atlapulgite 10-100, white carbon 10-40, the mica 10-30 of silication, silicone oil 3-20 by following parts by weight of raw materials proportioning and step; With above-mentioned batch mixes, thermal current 80-140 ℃ constant temperature dewaters to moisture content below 0.3%, and constant temperature is crushed to the granularity of regulation.Ammonium phosphate powder extinguishing agent of the present invention has advantages such as production cost is low, and hydroscopicity is low, and the product storage period is long.

Description

The preparation method of ammonium phosphate powder extinguishing agent
Technical field
The present invention relates to the fire-fighting fire extinguishing technology, specifically the preparation method of ammonium phosphate powder extinguishing agent.
Background technology
Ammonium phosphate powder extinguishing agent is called for short ABC powder extinguishing agent, is the human alternative substitute of breathing out imperial material of protection ozone layer that is.At present; The primary raw material that countries in the world are used to produce ABC dry powder uses thermal phosphoric acid one ammonium usually, this raw material accounts for the 70-80% of product totle drilling cost valency, use thermal phosphoric acid one ammonium to produce ABC powder extinguishing agent following shortcoming is arranged: 1, cost height, the cost of one ton of thermal phosphoric acid one ammonium of domestic production is not less than 5500 yuan; 2, hydroscopicity height, hydroscopicity is high can to reduce dry powder agglomeration resistance ability, shortens the storage life of dry powder in bottle.
Summary of the invention
The preparation method who the purpose of this invention is to provide the ammonium phosphate powder extinguishing agent that a kind of production cost is low, hydroscopicity is low, the products-supply time is long.
The present invention is achieved in that the present invention is a main material production ABC dry powder with phosphoric acid by wet process one ammonium, and concrete grammar is to produce by following parts by weight of raw materials proportioning and step:
1) gets white carbon 10-40, the mica 10-30 of phosphoric acid by wet process one ammonium 300-900, calcium carbonate 30-450, atlapulgite 10-100, silication, silicone oil 3-20;
2) with above-mentioned batch mixes, thermal current 80-140 ℃ constant temperature dewaters to moisture content below 0.3%;
3) constant temperature is crushed to the granularity of regulation.
Ammonium phosphate powder extinguishing agent of the present invention compared with prior art has the following advantages:
1. production cost is low, than the low 45-60% of existing ammonium phosphate dry-powder production cost;
2. hydroscopicity is low, compares with existing ammonium phosphate dry-powder and hangs down 40%, and the product storage can prolong 1 year;
3. electrical insulation capability improves behind the adding mica;
4. all the other indexs are not less than existing ammonium phosphate dry-powder.
The specific embodiment
Embodiment 1:
Produce ammonium phosphate dry-powder by following parts by weight of raw materials proportioning and step:
1) gets 10 kilograms of white carbons, 10 kilograms on the mica of 300 kilograms of phosphoric acid by wet process one ammoniums, 30 kilograms in calcium carbonate, 10 kilograms of atlapulgites, silication, 4 kilograms of silicone oil;
2), dewater to moisture content below 0.3% with thermal current 85-90 ℃ constant temperature with above-mentioned batch mixes;
3) constant temperature is crushed to the granularity of regulation.
Embodiment 2:
Produce ammonium phosphate dry-powder by following parts by weight of raw materials proportioning and step:
1) gets 20 kilograms of white carbons, 20 kilograms on the mica of 600 kilograms of phosphoric acid by wet process one ammoniums, 150 kilograms in calcium carbonate, 50 kilograms of atlapulgites, silication, 10 kilograms of silicone oil;
2), dewater to moisture content below 0.25% with thermal current 90-110 ℃ constant temperature with above-mentioned batch mixes;
3) constant temperature is crushed to the granularity of regulation.
Embodiment 3:
Produce ammonium phosphate dry-powder by following parts by weight of raw materials proportioning and step:
1) gets 40 kilograms of white carbons, 30 kilograms on the mica of 900 kilograms of phosphoric acid by wet process one ammoniums, 450 kilograms in calcium carbonate, the silication of atlapulgite double centner, 20 kilograms of silicone oil;
2), dewater to moisture content below 0.1% with thermal current 110-140 ℃ constant temperature with above-mentioned batch mixes;
3) constant temperature is crushed to the granularity of regulation.

Claims (1)

1, a kind of preparation method of ammonium phosphate powder extinguishing agent is characterized in that producing by following parts by weight of raw materials proportioning and step:
