Asbestos is dissolved because of the high temperature infrared rays. The technology that can do the detoxification without peeling off is developed.

Asbestos is a cheap, strong heat insulator from about the latter half of 1960. It was used for a lot of buildings. However, when man absorbs the detailed fiber generated from asbestos, it causes inside Cawa and the lung cancer. A severe limitation has been installed now.

Very large scale processing of peeling off by the hand work etc. in the room sealed up with the vinyl sheet etc. so that the worker full-armed so as not to breathe in asbestos by dustproof wear and the mask should not leak the dispersing asbestos outside is needed for the processing though repair work is one by one done in the building where the asbestos construction materials were used in a sweet standard at the use this time. It is doubly strictly packed afterwards, and in addition, it reclaims in an industrial final disposal site of "Management type" as special management industry waste and it is disposed. A high cost and an advanced technology are necessary. Furthermore,'It only peels off then and there. It processes it in other places. 'Two or more processes are necessary.

The enterprise that can do these a series of work is limited, and processing doesn't catch up, and the society has come into question in respect of processing also in the required urgent building because of order waiting of work as the unlawful removal work and the renunciation occur, too.

In the technology developed this time, the heating device with an infrared rays reflector of an oval type is developed based on the halogen lamp based on the idea of a handy infrared rays heating device that can make the high temperature announced in 2004 achievement. A fibroid form that became a direct problem of asbestos was melted by irradiating the light of 1500 degrees or more (It seemed that at least 1600 degrees or more from melting of the rock wool with 1600 melting points) and melting the object, it succeeded in the shape of "Gem", and it succeeded in.

This technology and 'It has melted' asbestos.

In addition, it is expected, "The detoxification can be done by not influencing concrete and burning only the sprayed asbestos" from spraying and there was no damage in the concrete that exists in the layer under asbestos when experimenting.

Concept chart of technology (on) and animation high temperature's dissolving (under). Animation can be referred to on the release page.

This experiment is the one that it is small-scale and the printing area is small. The processing costs of a great reduction in the work cost and the safety improvement, etc. when working can be greatly decreased by enlarging the device to process a large area in the future and the simplification of work be attempted. When peeling off, provision can be made handy not only making to powerlessness and being able then and there the processing of asbestos without purposely carrying to another place in a word but also the peel though the state of the asbestos of the life concerning the generated detailed fiber.

Part is assumed to be production of the prototype requesting the opinion of an existing asbestos processing enterprise in the laboratory in 1-2 years, and to be want practical use in 3-4 years according to the report.
