| 摘要 |
FIELD: process engineering.SUBSTANCE: invention relates to dry jet machining for cleaning solid surfaces, particularly, to special abrasive components suitable to this end and to method of their production. Surface cleaning is carried out by particles of alkaline earth metal natural carbonate unshaped in deposition or sintering sized to 100-500 mcm that features Moos hardness smaller than 4 and water content level lower than 5 wt %. Said particles are obtained by whatever dry grinding of said natural carbonate and screening to reduce the amount of fine particles.EFFECT: higher efficiency of cleaning.22 cl, 3 dwg, 9 ex |
