About
Circulating blast method®And what is it?
The Circulating Blast Method® is a blasting technique that utilizes highly wear-resistant metallic grinding materials. It involves collecting and sorting both the detached coating residues and the used grinding materials during the blasting process, and then recycling the grinding materials for further use. By recycling the grinding materials, the generation of industrial waste equivalent to the amount used is reduced, resulting in a decrease in environmental impact. Additionally, the generation of dust particles during the blasting process is minimized.
Reduction of industrial waste "Recycling and Reuse System"
研削材は使い捨てのスラグ系の非金属系ではなく、破砕しない金属系のスチールグリットを使用します。回収された研削材は塗膜くずと共に真空回収装置によって回収され、選別装置で重量差によって塗膜くずと選別。その後ホッパータンクに戻り、再び噴射されるのです。この際、エアドライヤーにより湿度上昇による研削材の固結やサビを防いでいます。
これが研削材による産業廃棄物を最大限削減可能にした「循環再利用システム」です。

Do not make grinding materials into industrial waste
By changing the grinding material for peeling the paint film from the sand to a metal that can be recycled and reused, we succeeded in turning industrial waste into only the paint film waste that has been peeled off..
The reduction amount is 1/40 of that of the conventional method.
In the last fiscal year, we contributed to the reduction of about 65,000 tons of industrial waste.

Reduction of dust generation
循環式ブラスト工法®︎は、従来工法と違い耐摩耗性の高い「金属系研削材」を使用するため、研削材の破損による粉じんを最小限に抑制。
地球環境だけでなく作業員の健康も守ります。
良好な品質確保は良好な作業環境により実現します。

Low cost, improved work efficiency
In the construction of 1,000 square meters, approximately 1t of paint film waste and 40t of grinding material waste were discharged.The recycling and reuse system, which uses the difference in the weight of the coating film waste and the grinding material to separate the waste, has made it possible to make only the coating film waste.
(04)
Greenhouse gases significantly cut
Since industrial waste becomes only paint film waste, greenhouse gases emitted during transportation and disposal are also reduced.
Last year, we succeeded in reducing greenhouse gas emissions by approximately 13,800 tons and 5.6 units at the Tokyo Dome.

当社は、循環式ブラスト工法®のパイオニア的存在であります。
しかし、当工法の普及とともに、同様の効果を謳う品質や廃棄発生量に大きなばらつきがある類似工法がいくつかあるのが現状です。
建設技術審査証明取得技術の取得により、循環式ブラスト工法®に一つの「物差し」が出来た今、類似工法には充分にお気をつけください。
Do you use hard (brittle) grinding materials?
Grinding materials with high hardness have a low life value, wear quickly, and are prone to sticking to steel, which leads to an increase in industrial waste and a decrease in coating quality.
is the sorting device integrated with the blast tank?
If the sorting device and the blast tank are not integrated, there is a risk that harmful dust will scatter around the construction site.
Do you use a blast-only curing sheet?
It is possible to prevent the leakage of harmful dust by curing and construction with a sheet dedicated to blasting.
Do you manage the PCB contents separately from other equipment?
If work is performed without a clear distinction between dedicated PCB materials and lead materials other than PCBs, there is a risk of contamination of sites that do not contain PCB.
Is it equipped with a suction force that can efficiently recover metal-based abrasives?
If the suction force is insufficient, the grinding agent cannot be recovered efficiently and the efficiency of the blasting operation falls, leading to delays in construction periods and increases in construction costs.
