Gelatin type

Domenek et al. (2008), released measurement of the intrinsic viscosity of gelatin type B in water solution at 42°C, where given values were of 27 cm /g and 70 cm / g. 

Gelatine explosives are more costly in raw materials than the powder or semi-gelatine types, although this can to some extent be offset by greater ease, and therefore less expense, in manufacture. Their popularity throughout the world rests on a number of important advantages over other available explosives ... 

In other explosives of a gelatine type some form of combustible is normally present. Most combustibles contain pores which hold air and they also assist mechanically in the trapping of air bubbles in the explosive. As a result, the lower the nitroglycerine content of a gelatine explosive, the easier it is to obtain adequate sensitiveness to commercial detonators. In the particularly difficult cases such as the higher strength gelignite... 

Another hazard is that cartridges fired early will cause compression in other holes and thus desensitise the explosive. To overcome this a sensitive explosive is required and one of semi-gelatine type is used in Britain. 

The method of mining is somewhat like driving two sets of tunnels at right angles through the strata. Most mines of this type do not present any hazard from methane and therefore non-permitted explosives can be used. The selection of powder or gelatine type of explosive depends on the nature of the rock and particularly on the wetness of the mine.

These stabilizers are added to the formulation in order to stabilize the emulsion formed during particle preparation. These stabilizers, however, can also influence the properties of the particles formed. The type and concentration of the stabilizer selected may affect the particle size. Being present at the boundary layer between the water phase and the organic phase during particle formation, the stabilizer can also be incorporated on the particle surface, modifying particle properties such as particle zeta potential and mucoadhesion (203). Other polymers have also been evaluated as stabilizers in earlier studies such as cellulosic derivatives methylcellu-lose (MC), hydroxyethylcellulose ( ), hydroxypropylcellulose (HPC), and hydroxypropylmethylcellulose (HPMC), as well as gelatin type A and B, carbomer and poloxamer (203).

Chlorate Cheddites may be subdivided into nongelatin- and gelatin- types. The non -gelatin-type Cheddites are in the form of soft grains, white or yellow in color, unless they have been artifically colored by some oi 1-sol dyes in order to distinguish one type from another. They are readily compressible and in order to obtain the full expl power their density should be carefully controlled. 

The gelatin-type Cheddites are plastic type expls which do not harden in storage.

For gelatin-type Cheddites, the nitro-compds(see under manuf of non-gelatinized types) are mixed with NC NG and heated to ca 40° until the mass becomes uniform. Then a finely powdered chlorate is added and coating is conducted with stirring, but without raising the temp(Ref 23)...
