Text Appearing Before Image:
sives, en même temps, enaméliorer leur qualité. Un grand nombre de chimistessont à lemploi de la compagnie, constamment occupées àaméliorer ses explosifs et à faire des épreuves journalièresde ces produits sur divers travaux, de façon à les maintenirà un haut degré de perfection. La compagnie a aussi uneéquipe dhommes expérimentés dans la manipulation desexplosifs, qui parcourent le pays, observant les travauxsur lesquels on se sert dexplosifs et démontrent aux con-sommateurs comment sen servir le plus avantageusement.Tout cela est fort coûteux, mais permet à la CanadianExplosives Limited de sassurer quelle vend les meilleursexplosifs qui peuvent être fabriqués, et aussi de fournir leconsommateur le genre dexplosif qui est le plus appropriépour le travail à faire. Les quantités et les tableaux donnés dans ce manuelsont basés sur les résultats connus des marques C.X.L.,et nous nen garantissons pas dautres marques. Novembre, 1911. CANADIAN EXPLOSIVES Limited.
Text Appearing After Image:
EXPLOSIFS LES explosifs sont sous forme de solides ou liquides quipeuvent être changés instantanément par une étin-celle, une chaleur intense ou un choc puissant, en desgaz ayant une centaine de fois le volume de lexplosif soussa forme première. Le charbon et le bois sont trans-formés lentement en grand volume gazeux par la combus-tion; leau est aussi lentement transformée en une grandequantité de gaz (vapeur) en la faisant chauffer. Ceci esttoute la théorie des matières explosives et explique, en peude mots, ce qui serait autrement difficile à décrire, et quiest facilement compris si lon se rappelle cette théorie.Les explosifs servant à la mine sont divisés en deux classes.Les explosifs à basse pression, ou poudre à miner, qui fontexplosion au moyen dune étincelle, et les explosifs à hautepression, connus sous le nom de dynamite, qui éclatent parun choc violent. POUDRE A MINE La Poudre à Mine est noire et est de nature granuleuse,en grains de différentes grosseu
