The present invention relates to a technique for manufacturing graphene and, more particularly, to a method for manufacturing graphene and a method for manufacturing a conductor using the graphene manufacturing method, which uses the exfoliating or transferring functions of various structures having the physical properties and adhesion peculiar to graphite to manufacture graphene on a large scale and also an electrical conductor or a thermal conductor from the graphene. One aspect of the method for manufacturing graphene and the method for manufacturing a conductor using the graphene manufacturing method is that the method for manufacturing graphene includes: (a) exfoliating or transferring a graphite material onto at least one structure to form graphene particles on the surface of any one of the at least one structure; (b) releasing the graphene particles from the structure; and (c) combining the released graphene particles to form graphene. Another aspect of the method for manufacturing graphene and the method for manufacturing a conductor using the graphene manufacturing method is that the method for manufacturing graphene includes: (a) consecutively exfoliating or transferring a graphite material onto a plurality of structures to form graphene particles on the surface of any one of the plural structures; (b) releasing the graphene particles from the structure; and (c) combining the released graphene particles to form graphene.

A combustion control method for a regenerative combustion type heat treatment furnace. When alternately switching the combustion operation and the heat storage operation in a pair of regenerative burners, the slave fuel gas supply pipe and the air supply pipe in each regenerative burner are The quantities of fuel gas and combustion air supplied from the tube are fixed, so that proper combustion can be performed stably. When switching between the combustion operation and the heat storage operation in a pair of regenerative burners (20), in the regenerative burner (20a) in combustion operation, the fuel gas supply pipe (28a) and the air supply The supply of fuel gas and combustion air supplied from the pipe (24a) decreases from the normal combustion state, and in the regenerative burner (20b) in the heat storage operation, the fuel gas supply pipe (28b) passes through the fuel gas supply pipe (28b) ) and air supply pipe (24b) to supply the fuel gas and combustion air supply from the stop state increased, and in a pair of regenerative burners, through the fuel gas supply pipe and the air supply pipe supplied from The supply of fuel gas and combustion air is fixed.

The invention relates to an AB type aqueous fire extinguisher which comprises a simple fire extinguishing container and an aqueous fire extinguishing agent packaged in the simple fire extinguishing container. The aqueous fire extinguishing agent comprises a component 1 and a component 2, the component 1 is water, and the component 2 is a main fire extinguishing agent body. The main fire extinguishing agent body is composed of, by weight, 8-20 parts of ammonium chloride, 5-15 parts of carbonate, 13-30 parts of diammonium hydrogen phosphate and 1-15 parts of bicarbonate. The aqueous fire extinguishing agent is packaged in the impact damage type container or the pressure storage type spraying container and made into manual casting type fire extinguishing liquid bombs or fire extinguishing mist spray, the fire extinguishing speed is high, and instant fire extinguishment can be achieved. The AB type aqueous fire extinguisher is small in size, low in weight, convenient to carry and low in cost, fire extinguishment can be achieved rapidly during a quite short period of time for A type fire disasters and B type disasters, reburning is avoided, the safety is high, an operation method is simple, and the AB type aqueous fire extinguisher is suitable for people of all ages to use and can serve as a simple standing fire extinguishing tool for homes, offices and the like.

The invention provides a combustion control method of a regenerative-combustion heat treatment furnace, wherein during the alternated switching of the combustion orpeation and the regerative operation of a pair of regenerative burners, the strong combustion at the beginging of the combustion of the regerative burner operated in the regenerative action is inhibited. In the regenerative-combustion heat treatment furnace (10), a fixed amount of combtuion gas is supplied from a fuel gas supply device (30) to the fuel gas supply pipes (28a,28b) of the regenerative burners (20a,20b). During the alternated switching of the combustion orpeation and the regerative operation of the pair of regenerative burners, before the decreasing of the quantities of the fuel gas and the combustion air supplied by the fuel gas supply pipe (28a) and the air supply pipe (24a) in the regerative burner (20a) operated in the combustion action, the fuel gas and the combustion air supplied by the fuel gas supply pipe (28a) and the air supply pipe (24a) are supplied to the regerative burner (20b) operated in the regenerative action so as to start the combustion of the regerative burner (20b).
