Match glue

The match industry consumes animal glue in the manufacturing of strike-anywhere, book matches, and wooden safety matches. Glues of various tests and foam characteristics are specially formulated. The glue acts as a binder for the ignition chemicals, combustible fillers, and inert materials and is also an important contributing factor in the formation of a head of correct density, form, and strength. 

A safety match head is, essentially, K chlorate in a matrix of animal glue. The striking strip is composed of red P in a similar binder. Use of additives and adjustments in the mfg process results in a safety match which ignites easily when rubbed on the striking surface. The friction and contact of K chlorate crystals with red P results in the ignition of the match head which, in turn, causes the ignition of paraffin impregnated in the match splint... 

A safety match requires for its ignition a rubbing on a "striking strip" which is covered with mixture such as consisting of red phosphorus 53, Sb sulfide 42 charcoal 5% in a binder such as NC lacquer, animal glue, dextrin, casein, plus hardener. Sb sulfide and charcoal serve as extenders to the phosphorus. 

The head of a safety match consists of K chlorate 45-55, animal (hide) glue (as a binder) 9-11, sulfur or rosin 3-5, extender (starch, dextrin) 2-3, neutralizer (ZnO.or Ca carbonate) 45-55, infusorial earth 5-6 other siliceous filler 15-32%. Fractional percentages of a soluble burning rate catalyst, such as K di-chromate, also soluble dye stuffs, etc... 

Zinc oxide has a wide range of uses apart from its use as an artist s pigment where it provides a more translucent white than flake white or titanium white. It is used in cosmetics, driers, quick-setting cements with syrupy phosphoric acid or zinc chloride in dental cement in the manufacture of opaque glass, enamels, car tyres, white glue, matches, white printing inks and porcelain. The photophysics of zinc oxide has been reviewed.1468 ... 

Squeeze bottles, oil cans, and pressurized glue guns permit precise and speedy adhesive application. By adjusting the pressure, the rate of adhesive flow can be matched to the production rate. These devices can apply the adhesive or sealant inside a blind hole or limited-access area. The tip of the applicator can be used to deliver multiple spots of adhesive. 

Mixtures for Matches, For sulphur dips Phosphorus, 3 parts glue, 5 parts sand, 1 part incorporated below 100° Fahr., with 10 parts of water. Or, phosphorus, 5 parts fine sand, 4 parts red ochre, 1 part (or, ultramarine), part gum-arabic, 5 parts, in 6 pints of water (or, 4 parts of glue in 9 parts of water). For etearine dips Phosphorus, 3 parts brown oxide of lead, 2 parts turpentine, i part, softened in 3 parts water. Instead of the brown oxide, 2 parts of red lead stirred up with i part of nitno acid mar bo used. 

A different binding medium was identified in MS 965 (Rockefel-ler-McCormick New Testament), however. Figure 5 shows the spectrum obtained from a sample of the manuscript s sizing material. Although the spectrum is clearly not that of egg yolk, it has the features of a predominantly protein component. The protein-containing binders used in that period are presumed to include casein, egg white, and hide glue (25). The spectrum closely matches that of hide glue (26). 

The addition of potassium dichromatc to the glue is stated to make the match co.mposition gradually damp owing to the oxidation of the glue. 

Liquid Glw can be obtained by treating too parts of glue with 140 parto of water and l6 parts of nitric acid it still retains the a esivc power of the glue used in its production, but does not gelatinise. This glue, and also liquid ghie made with acxtic acid, will not serve for the manufacture of match compositions. 

These are the same as for the match compositions. Manganese dioxide, the sulphides of antimony, powdered charcoal, amorphous phosphorus potassium chlorate, glass powder, etc., as frictional materiab chalk, etc., as hlling materials umber and the like as colouring matters glue, gelatin, and dextrin as binding nuterials.
