摘要： PURPOSE:To enable energy-saving drying of laver sheet in high quality and production efficiency by radiating far infrared ray from an external source to a far infrared-radiating ceramic applied to a laver screen and utilizing the absorbed far infrared ray for the drying of a laver sheet. CONSTITUTION:A laver sheet pasted on a laver screen is transferred into a drying apparatus and dried with far infrared ray radiated from a far infrared ray radiating ceramic such as alumina. In the above process, far infrared ray transmitted from external source is absorbed to the far infrared ray radiating ceramic attached to the laver screen and the absorbed far infrared ray is utilized for the drying of the laver sheet. Preferably, the far infrared ray radiating ceramic at the laver-screen side is calcined at a low temperature and the far infrared ray radiating ceramic at the drier side is calcined at a high temperature.

摘要： PURPOSE:To obtain a laver screen capable of drying and finishing a laver sheet in a short time at a low temperature without deteriorating the quality of raw laver by arranging a plurality of core materials made of a synthetic resin containing specific far infrared radiating ceramic particles. CONSTITUTION:The objective laver screen can be produced by dispersing far infrared-radiating ceramic particles having a far infrared emissivity of >=75% (preferably >=90%) at wavelength of 5-20mum at 30-40 deg.C e.g. in a solvent at a ratio of 1-50wt.%, filling and sealing the dispersion in a hollow part of a core material made of a synthetic resin and arranging a plurality of the obtained core materials containing the far infrared-radiating ceramic particles. As an alternative, a laver sheet can be effectively dried by the use of a laver-drying apparatus produced by dispersing said particles in a resin paint at a ratio of 5-60wt.% and applying the dispersion to the surface of the inner wall of the drying apparatus and the surface of internal equipments.

CONSTITUTION:Graphite raw materials 1 is inflation-treated in a heating and inflating furnace 2 after chemical treatment, made into inflated graphite 1' and cut down on a belt conveyor by a fixed quantity. Then after leveling of the same to equal height with a raw material height adjusting plate 4, the same is prerolled with a prerolling upper belt 5 and prerolling roll 5a. Then finish rolling is performed with a six-stage finishing pressure roll. Bulk density control of the inflated graphite 1' at an outlet of a prerolling machine is performed so that the bulk density falls within a range of 0.1-0.8g/cm . At the time of the controlling it is performed according to degrees of the inflation treatment and prepressure drop. Then a pressure drop factor of rolling through upstream side finishing pressure rolls 6, 6-9,9 is made 50+ or -10%. Generation of a crack is prevented by letting bubbles go by controlling sudden pressure drop.

摘要： PURPOSE:To enhance reaction efficiency by processing with physical adsorption reaction or chemical reaction to a pelletized adsorbent in an environment of giving waves of roughness and denseness like sounds. CONSTITUTION:As the difference between the formation substance concentration and equilibrium concentration of reaction surface forms a reaction screwing force in chemical reaction, agitation is carried out to lower the surface concentration. On the other hand, often reaction is accelerated in the pores inside a substance in physical adsorption reaction, and agitation is not always function effectively. In that case, however, if reaction is proceeded under a sound field, the vibration of particles is generated in the sound field and the reaction surface is always diluted and renewed, which makes reaction screwing force larger and reaction is accelerated. For example, in a drain decoloration process for the treatment of gas liquid concentration separated from a coke oven gas, reaction is carried out with good efficiency by adding pelletized iron group adsorbents and providing a given sound field.

摘要： PURPOSE:To heat the heating surface of the titled panel, reduce the cost of a product and facilitate its manufacture by using an expansion graphite sheet for a plate heating body. CONSTITUTION:An expansion graphite sheet 1 is used for a heating body. A sheet 1 has a higher electric resistance and a larger heating quantity when current is applied perpendicularly to the surface than in parallel to it. The heating body 1 is heat insulated by a laminated plate building material 2, and a rigid material 3 is formed surrounding the periphery of a section of the laminated body. Inside the rigid material 3 is provided an insulation layer 4 attached to the laminated body by means of heat resistant binding agent 5. Current is applied to the heating body from an external power source through electrodes 6 for heating. The heating body is formed of the sheet 1, a sufficient heating quantity is obtained because of its direction, and because it is of a form of a plate, uniform heating is enabled. Used material is graphite only, thereby manufacture is easy, and a product can be obtained at a low cost.

摘要： PURPOSE:To obtain an expanded graphite sheet where a foreign matter hardly exists on the surface of the sheet and it possesses a smooth surface, by contriving smoothness of the surface by performing grinding of the sheet during a period extending from after preliminary rolling up to finish rolling. CONSTITUTION:Graphite raw materials fed to a heating and expanding furnace 2 through a hopper 1 is cut down by a fixed quantity after its expansion treatment and fed onto a belt conveyor. The top of the expanded graphite 3 is flattened by a leveling plate 4 and the same is compressed and rolled lightly by a preliminary rolling belt 5. In succession to the above, main rolling of a sheet 3' is performed with main rolling rolls 6, 7, 8, finish rolling is performed finally with a finish rolling roll 9 and then wound up round a wind-up roll 10 as a product sheet. Therefore, grinding cf the surface of the sheet 3' is performed during a period extending from after preliminary rolling up to the finish rolling and brush rolls 11, 11', a grinding roll 12 and a buffing roll 13 are used as a grinding device. Consequently, the surface of the sheet is smoothed, gloss is increased and an expanded graphite sheet whose oil resistance and water resistance have been improved can be obtained.
