Full hydraulic tunnel prospecting rig :
1. Small size, light weight and easy installation.
2. Three major components. Main unit, pump station, console.
3. The original transportation, prospecting and roadway can be put into production, which will protect the overall structure of the mine. It can also be used for surface drilling.
4. The drilling rig is flexible in layout, mechanically twisting and unloading the drill pipe, reducing the labor intensity of workers and improving work efficiency.
5, the use of box-type feeding frame, clamp clamping, power head rotary drilling, cylinder pull drill, can save the bulky rig.
6, with linkage function, centralized operation through the console, simple and safe, can be stepless speed regulation.
7. Hollow shaft design, the length of the drill pipe is not limited by the drilling process. Can drill at any angle of 360 degrees.
8, good disintegration, easy to move and transport. The Φ33-Φ43 drill pipe can be used in the same machine, and the replacement takes only 15 minutes.
Food-grade 85 phosphoric ACID has a clear appearance and no odor. The liquid has a thick consistency and can be easily dissolved in water. The density of this chemical is about 1.67 kg/l. Phosphoric acid food-grade 85 is highly acidic with a pH level less than 1.
Properties:
colorless and transparent viscous liquid. It is odorless, sour, melting point 42.35 ℃, easily soluble in water, soluble in ethanol, can irritate the skin and cause inflammation, destroy body tissues, and have hygroscopicity.
Uses:
Used as sour agent and yeast nutrient, can be used as seasoning, canned, refreshing drink sour agent, used as yeast nutrition source when brewing, to prevent multiplication of bacteria.
Phosphoric acid is mainly used in the manufacture of various phosphate, such as ammonium phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, etc and condensation phosphate class.
It should be stored in a cool, ventilated warehouse. In high-concentration phosphoric acid, it is necessary to pay attention to heat preservation in cold regions in winter to prevent freezing and leakage of containers. Do not store and transport together with alkalis, toxic materials and other corrosive materials. Protect from rain and direct sunlight during transportation. Handle with care during loading and unloading. Violent impact is strictly prohibited to prevent the packaging container from rupturing. In case of fire, dry sand or dry powder fire extinguisher can be used for fighting.
