Abstract
The invention discloses a water-based carried inactive nitric powder and making method, which contains inactive nitric powder, wherein the exterior of the inactive nitric powder is cladded with coating material to dissolve in the organic solution without dissolving in the water. The making method comprises the following steps: 1. allocating fitful quantity of coating solution; using the coating material for fitful quantity of organic solution; 2. cladding the coating liquid on the exterior of inactive nitric powder through cladding machine. The invention can form coating material of the film on the surface of inactive nitric powder, which can squeeze inactive nitric powder into formation based on water base as carrier.
Description
Technical field
The present invention relates to a kind of nitric acid powder and preparation method thereof, relate in particular to a kind of water-based carrying non-active nitric acid powder and preparation method thereof.
Background technology
To be the nineties introduce from Ukraine existing nitric acid powder technology, and the solid nitric acid powder that is white in color is nonactive, is insoluble to oil base (as dewatered oil and diesel oil etc.), and be soluble in water base (as water, ethanol etc.); Solubility with temperature in water raises and increases, and can decomposite the HNO of strong oxidizing property
3At present, conventional method is that non-active nitric acid powder is clamp-oned the stratum with crude oil as carrier, this method cost height, and complex procedures.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of usefulness is water base can clamp-on the stratum water-based carrying non-active nitric acid powder as carrier.
And then the present invention also provides a kind of manufacture method of water-based carrying non-active nitric acid powder.
A kind of water-based carrying non-active nitric acid powder of the present invention comprises: non-active nitric acid powder is covered with in this non-active nitric acid powder particulate external packets and is dissolved in organic solution but water-fast coating material.
Further, described coating material is stearic acid resin, mono-glycerides or acrylic resin.
Further, described organic solution is toluene, dimethylbenzene, ethanol or ethylene glycol.
The manufacture method of a kind of water-based carrying non-active nitric acid powder of the present invention comprises the steps:
Step 1: dispose an amount of dressing solution, be about to be dissolved in organic solution but water-fast coating material is used for an amount of organic solution;
Step 2: above-mentioned coating liquid is coated by the particulate outside of dressing machine at non-active nitric acid powder.
The present invention has water insoluble and can form the coating material of overlay film on non-active nitric acid powder particulate surface by being covered with in non-active nitric acid powder particulate external packets, water basely just non-active nitric acid powder can be clamp-oned the stratum as carrier thereby adopt.Production technique of the present invention is simple, and cost is low, and greatly reduces the complicacy of non-active nitric acid powder being clamp-oned the stratum.In addition, there is not like product to sell in the market yet.
Embodiment
The manufacture method of water-based carrying non-active nitric acid powder of the present invention is specifically carried out according to following steps:
Step 1: the coating liquid of preparation 1000～2000mL, the coating material STE (stearic acid resin) that is about to 10～50g under agitation is dissolved in the organic solvent toluene;
Step 2: put into 600～800g water-soluble solid nitric acid powder in the dressing machine and it is carried out predrying, the blower fan frequency control is at 18～22HZ, and inlet temperature is controlled at 50～60 ℃;
Step 3: treat to open behind the core complete drying feed liquor peristaltic pump of dressing machine, the control rotating speed is 6～10 commentaries on classics/min, and the dressing solution that configures is carried out dressing to the water-soluble solid nitric acid powder;
Step 4:, obtain being coated with the water-soluble solid nitric acid powder of STE material to being carried out drying by the water-soluble solid nitric acid powder behind the dressing.
By the above-mentioned water-soluble solid nitric acid powder that is coated with the STE material that obtains is that outward appearance is white particle dispersion, drops in the water not dissolve at normal temperatures, and acid content is about about 40%, water basely as carrier it is clamp-oned the stratum thereby can adopt.After formation temperature reached 60 ℃, the STE material melted, thus make the water-soluble solid nitric acid powder be dissolved into water base in.
The consumption of above-mentioned coating material needs only to satisfy nitric acid powder is all coated, and it is just passable to obtain the dissolving of suitable height (such as 60 ℃) back in temperature, generally can be 1～6 times (mass ratio) of water-soluble solid nitric acid powder.Coating material can be SET (a stearic acid resin), also can select mono-glycerides or acrylic resin, as long as satisfy and nitric acid powder can be coated, is dissolved in organic solution but water-fast requirement is just passable.Organic solvent can be a toluene, also can be organic solvents such as dimethylbenzene, ethanol, ethylene glycol.
