Countersunk/Counterbore Pot Magnets

What are neodymium magnets? Are they the same as "rare earth"?

Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. neodymium magnets with countersunk holes are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.

Due to its convenience in installation, wall mounted speaker are  quite popular in indoor voice reinforcement projects for back ground music and paging. As the best wall mount speakers for music, DSPPA DSP6061 series wall mounted pa system  has been the favorite product for its wonderful sound effect and reliability. Its housing uses thickened industrial ABS, while grille uses stainless, durable for long term use. The series has 1 high pitch driver unit of 1”, and low pitch driver units of 4”, 5”, 6.5” and 8“. In 2016, DSPPA has launched an improved wall mount speaker series—DSP8062 Series. Comparing to DSP6061 Series, it has more fashionable outlook, with low pitch driver units of 4” (RMS 20W), 5” (RMS 30W), 6.5” (RMS 40W).

It is an ideal choice for industrial and commercial applications in hotel, school, office and factory where background music and paging is needed.

By developing creative products during the past years. as pa system manufacturers, DSPPA has promoted the technologies of the fields like Professional Audio, Public Address and Conference System both in and abroad. DSPPA leads the orientation of Public Address development and will raise the PA technology to a higher level.

On the surface of the horizontal directional drilling (HDD) is not excavation surface conditions, the laying of a variety of underground utilities (pipes, cables, etc.) of a drilling way, it is widely used in water supply, electricity, telecommunications, gas, gas, oil and other pipeline construction, it is suitable for sand, clay, pebbles and other DeKuang, GREAT can choose different models according to different formation of pipeline construction.

The operating environment temperature is -15℃~+45℃.

Horizontal directional drilling technology is a new construction technology that combines the directional drilling technology of petroleum industry with the traditional pipeline construction method.

Directional drilling control direction:

Wired directional control: long distance, deep penetration, and large rig use

Wireless direction control: short distance, shallow crossing, and small and medium-sized drilling rig use, direction control is convenient and accurate but limited by depth, terrain, less use.

Commonly used directional well drilling products are Tricone bit and PDC bit.

Horizontal well is a kind of directional well.

Trenchless refers to the use of a variety of rock and soil drilling and digging equipment and technology, through guidance, directional drilling methods such as in the case of a very small part of the excavation surface (generally refers to the entry and exit) small area excavation, construction, replacement and repair all kinds of underground pipeline laying technology, not blocking traffic, not green, vegetation destruction, will not affect the stores, hospitals, schools and people's normal life and work order, solve the traditional excavation disturbance to the residents, the traffic, environment, the destruction of the surrounding buildings foundation and adverse effects, therefore has high social and economic effect.

Drilling a pilot hole, hole opener(Rock reamer) and pipe installation are the three basic steps of horizontal directional drilling (HDD).

Nitrification inhibitor refers to a class of chemical substances that inhibit the biotransformation of ammonium nitrogen into nitrate nitrogen (NCT). Nitrification inhibitors reduce the formation and accumulation of nitrate in soil so that it can reduce the loss of nitrogenous fertilizer in the form of nitrate nitrogen and the impacting on ecological environment. Some results show that, although nitrification inhibitor can reduce nitrogen leaching loss and greenhouse gas (nitrogen oxide) emission, it has a positive effect on improving fertilizer efficiency under certain conditions. However, nitrification inhibitors have not been widely used due to factors such as craftwork, cost and their own effects on the environment. It is necessary to search for some nitrification inhibitors which are effective in inhibiting nitrification and do not pollute the environment. 

Brief introduction of 3,4-Dimethylpyrazole Phosphate

• They can selectively inhibit the activity of nitrobacteria in soil. 
• Ammonium nitrogen can be absorbed by soil colloids and not easily lost. However, under the condition of soil permeability, ammonium nitrogen can be transformed into nitrate nitrogen under the action of microorganism, which is called nitrification.
• The speed of reaction depends on soil moisture and temperature. The speed of nitrification is very slow when it is below 10 °c. When the temperature is above 20 °C, the reaction rate is very fast. Except for some crops, such as rice, which can absorb ammonium nitrogen directly under irrigation, most crops absorb nitrate nitrogen. But nitrate is easy to be lost in soil. Rational use of nitrification inhibitors to control the rate of nitrification reaction can reduce the loss of nitrogen and increase nitrogen use efficiency. Nitrification inhibitors are usually mixed with nitrogen fertilizer and then applied.
