| 单词 | pyroxyline |
| 例句 | He also, in 1846, experimented with the then newly discovered explosive, gun-cotton, and with pyroxyline made from paper and other materials. The History of the Medical Department of Transylvania University They are produced commercially and are known as "gun cotton" or "pyroxyline". The Dyeing of Cotton Fabrics A Practical Handbook for the Dyer and Student One of the largest manufacturers of pyroxyline in the States uses the "Memphis Star" brand of cotton. Nitro-Explosives: A Practical Treatise The inventor of the gun then prepared for the French some wafers of pyroxyline canvas, which were placed next to the primer, securing thereby prompt ignition without the production of any smoke. Scientific American Supplement, No. 821, September 26, 1891 On the other hand, pyroxyline had these advantages—it was not affected by dampness, it did not foul the gun-barrels, and its explosive force was four times greater than that of gunpowder. The Mysterious Island These solvents are those which also develop a solvent action when heated to their melting point in combination with pyroxyline. Nitro-Explosives: A Practical Treatise The solution of the pyroxyline nitrates in ether and alcohol is known as collodion, and is used in photography and in medical and surgical work. The Dyeing of Cotton Fabrics A Practical Handbook for the Dyer and Student The usual proportion of the constituents is 2 parts pyroxyline and 1 part camphor. Nitro-Explosives: A Practical Treatise This formula is very largely used for the production of pyroxyline varnish, which is used for varnishing pens, pencils, &c., also brass-work and silver-ware. Nitro-Explosives: A Practical Treatise “Try, then, Pencroff,” answered the engineer; “but don’t use our powder, whose stock I do not want to diminish; use pyroxyline, whose supply will never fail.” The Mysterious Island The nitro-cellulose produced by this formula is very insoluble in the compound ethers and other solvents of pyroxyline, and is seemingly only converted or gelatinised by the action of the solvent. Nitro-Explosives: A Practical Treatise By simply nitrating at a higher temperature than the cotton, the flax will yield a pyroxyline giving an equally fluid collodion. Nitro-Explosives: A Practical Treatise The manufacture of pyroxyline for the purpose of making celluloid has very much increased during recent years, and with this increase of production improved methods of manufacture have been invented. Nitro-Explosives: A Practical Treatise The hook at one end of the rod enables the workman to pull the pyroxyline apart, and thus ensures saturation of the fibre. Nitro-Explosives: A Practical Treatise “Can these cannon support the explosive force of pyroxyline?” asked the reporter, who was as eager as Pencroff to try their new artillery. The Mysterious Island These four classes include the greater number of the solvents of pyroxyline. Nitro-Explosives: A Practical Treatise The impregnation of the pyroxyline with the camphor is effected in a variety of ways. Nitro-Explosives: A Practical Treatise The composition is prepared as follows:—Nitro-glycerine is thickened with pyroxyline to the consistency of raw rubber. Nitro-Explosives: A Practical Treatise It appears to be merely a mixture of its components, since by treatment with appropriate solvents the camphor may be readily extracted, and on heating the pyroxyline burns away while the camphor volatilises. Nitro-Explosives: A Practical Treatise They were charged with pyroxyline, which, as we have said, has an explosive force fourfold that of gunpowder; the projectile was cylindro-conical in shape. The Mysterious Island Paper made from the pulps of sulphite and sulphate processes is capable of yielding a very soluble pyroxyline. Nitro-Explosives: A Practical Treatise From 30 to 35 lbs. of pyroxyline were produced in each of the fourteen days. Nitro-Explosives: A Practical Treatise This is done by employing about 75 to 85 per cent. of nitro-glycerine, and 15 to 25 per cent. of pyroxyline, according to the stiffness or elasticity of the compound desired. Nitro-Explosives: A Practical Treatise Field groups the solvents of pyroxyline into classes thus: Two of the monohydric alcohols; compound ethers of the fatty acids with monohydric alcohols, aldehydes; simple and mixed ketones of the fatty acid series. Nitro-Explosives: A Practical Treatise Thus they had the cellulose at hand, and the only other substance necessary for the manufacture of pyroxyline was nitric acid, which Smith could easily produce as before. The Mysterious Island The solvents of pyroxyline can be divided into general classes—First, those which are solvents without the aid of heat or solution in alcohol; second, those that are solvents when dissolved in alcohol. Nitro-Explosives: A Practical Treatise He found that after treatment with ammonia, pyroxyline assumed a slightly yellowish tinge, which was a sure sign of alkalinity. Nitro-Explosives: A Practical Treatise Mr Field says, "This is a significant fact when it is known that from this cotton an extremely soluble pyroxyline can be produced." Nitro-Explosives: A Practical Treatise Meantime, since the pyroxyline answered very well, there was no present need to use this powder. The Mysterious Island |
