The invention discloses a copper material surface detergent, which is characterized in that active ingredients mainly comprise the following ingredients and parts in mass: 10-13 parts of non-ionic surface active agent, 10-20 parts of anionic surfactant, 8-10 parts of silicon dioxide grinding agent, 0.1-2 parts of stabilizer, 5-8 parts of sulfamic acid, 5-10 parts of corrosion inhibitor and 2-5 parts of sodium bicarbonate. The copper material surface detergent is safe, easy to use and convenient; the non-ionic surface active agent and the anionic surfactant are adopted for compounding, so that the detergency is good, and the system can be stable for a long time due to the addition of the stabilizer; and since the silicon dioxide grinding agent with a particular grain diameter is added, the bright effect of the product can be strengthened.

The invention discloses a dry powder extinguishing agent and a preparation method thereof. The dry powder extinguishing agent comprises the following materials in percentage by weight: 80% of B-Mg sludge, 6% of sodium bicarbonate, 8% of potassium nitrate, 1% of sulfamic acid and 5% of an anti-blushing agent. The preparation method of the dry powder extinguishing agent comprises the following steps: S1, smashing the raw material B-Mg sludge; S2, through metering, adding 80% of B-Mg sludge, 6% of sodium bicarbonate, 8% of potassium nitrate, 1% of sulfamic acid and 5% of an anti-blushing agent ina mixing silicification device for mixing silicification; S3, drying the material subjected to silicification; S4, sieving the dried material; and S5, packaging the sieved material and metering to obtain a finished product. According to the dry powder extinguishing agent and the preparation method thereof, B-Mg sludge generated during the production process of a borax factory is utilized, the resource is reasonably utilized, the molecular particle size of B-Mg sludge is smaller than 15 microns, and a plurality of holes are formed in the surface, so that the surface contact area is increased and the adsorption capacity is high.

The present invention is directed to cocrystal forms of ((1S,2S,4R)-4-{4-[(1S)-2,3-dihydro-1H-inden-1-ylamino]-7H-pyrrolo[2,3-d]pyrimidin-7-yl}-2-hydroxcyclopentyl) methyl sulfamate of formula (I).
