Somax Blasting is a private enterprise found in Qingdao, China. The core business of the company is the sandblast appliances. Somax is a producer of sandblast nozzles of boron carbide and supplies with sandblast equipment, accessories and materials for work with powerful jet: metallurgical металургична slag, steel sand, glass grains, silicon carbide, aluminum oxide, etc.
The boron carbide is the third hard material after the diamond and the cubic borob nitride. The sandblast nozzle of boron carbide has excellent work characteristics and a good correlation "price - work life". According to the used sandblast materials, their time of usage can be from 1000 to 1200 work hours. The hardiness of the boron carbide nozzles is higher than those of silicon carbide 8 to 10 times; the corundum ones - to 16 times, the wolfram about 34 times, and those made of steel and tempered iron - over 100 times.
Due to the extraordinary hardiness of the material, even when aggressive abrasives are used, the boron carbide nozzles have the following advantages compared for example to those of the wolfram:
- Very long work life - 3 to 25 times longer life depending to the jet materials that are used;
- Lower exploitation expenses - about 3 times lower when the most aggressive jet materials are used. The usage of boron carbide instead of wolfram carbide allows the saving of $800 for 1000 work hours. (in each point if the operations!!!);
- Easier support - less changes, leading to less time lost for those changes;
- Easier manual operations - the nozzles of Boron carbide decrease the hardness of the operator, as they are 5 times lighter than those of wolfram carbide.
