Abstract

The invention provides several Process of making toy sand gun, it is directly to make silver fulminate with silver nitrate solution after precipitating silver-containing liquid waste with alkaline matter, and mixing medicine to add short-term when husky dry again after imitating deterrent and increasing humidity, improve that the tool and method of toppling over spice implements.

Description

A kind of Process of toy sand gun

The invention belongs to the novel process of toy firecracker.

The method of the husky big gun of traditional fabrication is to adopt solid-state silver nitrate and nitric acid and alcohol reaction to produce silver fulminate, adds then additive, silver fulminate (hereinafter to be referred as spice) and water is dialled with tipping pour on the sand, mixes to manufacture granulating after even.Waste liquid behind the silver fulminate processed still contains the composition of a lot of silver, and the silver of this part is to become argent, melting to purify by displacement reaction by adding again after salt makes it to generate silver nitride precipitation.It is standby to make solid-state Silver Nitrate again, and so whole technology exists the shortcoming of danger, trouble, contaminate environment and waste material.

The present invention is directed to these shortcomings, studied successfully a kind of safer, convenient and new technology method of saving material.

The present invention is realized by following several respects:

The first, precipitate the silver-containing liquid waste of doing behind the husky roasting and boiling as two means of processing crude drugs material with lime or other alkaline matters or carbonate, clean after the precipitation with nitric acid this precipitation to be dissolved and becomes certain density liquor argenti nitratis ophthalmicus, need not become the silver nitrate crystallization to this solution but directly measure this solution and nitric acid and alcohol reaction generation spice.This processing method has following advantage: one, the contained nitric acid of waste liquid is neutralized, thereby waste liquid does not pollute the environment; Two, save starting material; Three, enhance productivity, get flowing fluid ratio and weigh that to get convenient solid much quick in the balance because contain with the vessel of constant volume; Four, overcome with solid-state Silver Nitrate and directly reacted sometimes the danger that produces " medicine grain " (blocky silver fulminate).Owing to above three, four advantage is arranged,, had better be made into certain density solution for standby to it even therefore ready-made Silver Nitrate crystallization is arranged.

The second, employing has the vessel of some apertures to come the splendid attire spice in a side, and this moment, a foraminate side was towards height.When spice clean to finish and doping after, while portable vessel shakes a foraminate side direction is had a down dip, spice and water namely spray the little sand of having paved below splashing into equably from aperture, then medicine sand mixing.Dial down the method for spice if adopt to dial fall method according to tradition, spice is difficult to dial equably and pours on the whole Shamian Island, and accomplishes easily this point with this rule, just like this when mixed medicine sand safe ready many.

Three, the mixed husky technology of above second also can adopt spraying (penetrating) method that spice is sprayed onto in the sand, mixes medicine sand while spray spice.Sand can be to be layered on according to the conventional method on the cloth, also can be placed in the cylinder and roll; Spraying (penetrating) method can adopt the electronic method such as spray paint, also can adopt the manual method such as flit-gun, perhaps have behind the vessel splendid attire spice of being made by flexible plastic or rubber of some apertures the sealing of vessel cap jam-pack with the bottom, press vessel with hand again spice and water are ejected from aperture.If adopt the cylinder dress husky, roll while spray medicine, then the vessel of powder charge material can separate (cylinder has an open pore) with cylinder, also can connect together the two.The spice that sprays of spraying (penetrating) method becomes the mist droplet shape in a word, and spice and sand can very fast mixings, and greatly increase mixed husky security.

Four, husky roasting and boiling as two means of processing crude drugs material (with above-mentioned second, third, 2 identical, namely no matter be silver fulminate or other explosives) because very responsive (otherwise can not become husky roasting and boiling as two means of processing crude drugs material), when mixed medicine is husky and when wrapping husky big gun by hand, a little accidentally all can set off an explosion, therefore generally be to add suitable long-acting additive to adjust its sensitiveness, and all be to adopt wet medicine operation, more wet its sensitiveness of medicine sand is more low.But medicine sand is crossed to wet and will be had influence on the operation of manufacturing husky big gun.The invention provides a kind of effective means, Here it is adds short-term effect deterrent (can add other additives in addition) and increase its humidity when mixed sand in spice, mix husky back and reduce its humidity with the moisture absorption method, two kinds of methods can simultaneously and use also optional one of them.The moisture absorption method can or be used drier with dehumidifier, and it is the Reduced susceptibility that makes in a short time spice that short-term is imitated deterrent, and this deterrent is run away to lose efficacy because of volatilization and made spice recover original sensitiveness after a period of time.Such as glycerine etc., can keep the moisture of the medicine sand of doing nearly after its adds, and namely can vapor away after a period of time, medicine sand will recover original sensitiveness.

Adopt each process of above invention, all can receive desirable effect.

Claims (4)

1, a kind of husky roasting and boiling as two means of processing crude drugs material manufacture craft, it is characterized in that precipitating silver-containing liquid waste with lime or other alkaline matters or carbonate, precipitation becomes liquor argenti nitratis ophthalmicus with nitric acid dissolve after cleaning, with quantitative liquor argenti nitratis ophthalmicus and nitric acid and the husky roasting and boiling as two means of processing crude drugs material of alcohol reaction making silver fulminate.

2, the husky manufacture craft of a kind of husky roasting and boiling as two means of processing crude drugs is characterized in that having the vessel of some apertures to come splendid attire sand roasting and boiling as two means of processing crude drugs material with a side, and spice and water are sprayed from the vessel aperture equably and drip on the Shamian Island by shaking vessel, then spice and husky mixing.

3, the husky manufacture craft of a kind of husky roasting and boiling as two means of processing crude drugs is characterized in that adopting spraying (penetrating) method to be sprayed onto spice and water in the sand and mixing medicine sand.

4, the husky preparation method of a kind of husky roasting and boiling as two means of processing crude drugs is characterized in that adding short-term and imitates deterrent in spice; When mixed medicine is husky, increase the humidity of medicine sand, reduce again the humidity of medicine sand behind the mixing with the moisture absorption method.(two methods can be simultaneously and usefulness, also optional one of them).
