<p>PURPOSE:To make it possible to produce a liquefied gas bomb which is portable, safe and inexpensive by mixing fleon or halone into liquefied petroleum gas so that gage pressure of a mixture may become below 8Kg/cm<2> at 35 deg.C, and charging the mixture in a metal can for aerosol. CONSTITUTION:A mixture of about 4 parts of propane, about 5 parts of butane and about 1 part of halone is charged by about 60g in a tin plate can for aerosol being about 50mm in inside diameter and about 100mm in height. The gage pressure of the mixture shall be below 8Kg/cm<2> at 35 deg.C. When a valve of a gas bomb, namely the tin plate can, is connected with a tire valve of a bicycle tire from which air has vented to fill the tire with gas, applicable tire pressure can be attained in about 10 seconds. A metal can for the aerosol is convenient for carrying, and the combustibility of the mixture can be moderated by properly mixing fleon or halone into liquefied petroleum gas.</p> |
