M2 thickener

A1 soap in which about 50% of the org adds are derived from coconut oil, 25% from naphthenic acids and 25% from oleic acid. When stirred into gasoline at a temp range from 16—29°, M1 swells until the entire vol of gasoline becomes a more or less homogeneous gel M2 Thickener. A standard (for US Air Force) incendiary oil thickener. It is an intimate mixt of 95%Ml Thickener and 5% devolatilized silica... 

M2 Thickener It is pulverized Ml thickener with an antimoisture substance (attasorb clay) added in the ratio of lp attasorb clay to 19p Ml thickener. It readily absorbs moisture from the air, but not to the extent of M1 thickener, because less air circulates thru the pulverized particles the attasorb clay further lowers moisture absorption. A container may be resealed after part of the M2 thickener has been used provided it has had minimum exposure to air. Since M2 thickener is composed mainly of Ml thickener, it retains most of the characteristics of Ml, including the disadvantages of being manufd from critical material, absorption of water from the air, and sensitivity to moisture. 

As a general comparison with Ml thickener, only two-thirds as much M2 thickener is needed to obtain thickened fuel of the same consistency (Ref 7, p 9)... 

M2 Thickener A standard (for Air Force only) incendiary oil thickener. It is an intimate mixt of Ml thickener 95 devolatilized silica aerogel 5%- M2 thickener is an improvement over Ml, not only because of free-flowing faster setting characteristics, but also because the thickener itself ge 1 formed are more stable. It is used in fire bombs [Ref TM 3-215/AFM 355-7 (Dec 1963), p 4l]... 

Thermit (burning charge Mk I) Thermite, plain, incendiary Thickener, MI Thickener, M2 Thickener, M4 Titanium, Tech. 

NP Abbr for Napalm. Aluminum soap in powder form, used to gelatinize oil or gasoline for use in Napalm bombs or flame throwers. See also Ml, M2 Sc M4 thickeners... 

The fluffy product is extremely finely divided (particle size typically 7-40 nm, powder density 0.03-0.06 g cm-3) but nonporous (surface area ca. 200-400 m2 g-1). Like fused silica, silica fume is amorphous, and this, together with the small particle size, gives it relatively high solubility. It is used as a thixotropic thickening agent for epoxy resins, in special high strength... 

Fig 30). A smaller fire starter, M2, is designed to be carried in a pocket of the Air Force survial kit for use by downed AF cfew in starting fires under adverse climatic conditions. This device is a rectangular NC container, 0.5 x0.5 x3 contg 0.2oz of thickened kerosene and provided with an igniter which consists of a match-head mixture with a pull-type scratcher wire(Ref,... 

Determine the controlling area. The controlling area is the thickening area (165 m2) because it exceeds the area required for clarification (129 m2). 

Related Calculations. The hydraulic loading rate of 7.13 m3/m2 d at peak design flow is at the lower end of the recommended rate. To prevent septicity and odors, dilution water should be provided. Calculation of the dilution water requirements for average design flow is a homework problem. The thickener size of 16.15 m is within the maximum size of 20 m customarily recommended by thickener equipment manufacturers for use in municipal wastewater treatment. In actual design, round the thickener diameter to the nearest 0.5 m, or, in this case, 16 m. 

In comparative tests the CWS and NDRC models showed approximately the same range, sixty yards with thickened fuel and one-third of this with ordinary fuel. The former model was slightly heavier and held less fuel than the latter. The Army preferred the rugged CWS model with pyrotechnic ignition to the light NDRC model with electrical ignition, and adopted it as the standard model, M2-2 in March 1944. ...
