Urease inhibitor is a kind of substance that can inhibit the activity of soil urease, and it is a new technology which has been studied in urea or nitrogen compound fertilizer. Using soil urease inhibitor can effectively slow decomposition of urea into ammonia process, reduce soil NH4 + and NH3 concentration, soil fertility and crop fertilizer synchronization. 

NBPT is the most effective inhibitor of soil urease. Positive butyl thiophosphoric triamide as inhibitors of soil urease, efficient, non-toxic, on soil without side effects, and in the soil in the natural decomposition of ammonia and ammonium phosphate. NBPT can increase the efficiency of urea N by 30%.

NBPT(cas 94317-64-3) can by urea use 3-5 millionth of the amount of the proportion of flux of dissolved directly mixed with urea applied to the soil, can also according to a proper proportion through a certain preparation process growth effect of slow release compound fertilizer. This kind of long-term fertilizer containing NBPT is mainly used in the field crops and some growing vegetables, orchards, trees, corn, wheat, palm trees, etc.

N-(n-butyl) thiophosphoric triamide(nbpt) is currently one of the most effective soil urease inhibitors. Under normal use, agricultural fertilizers, mainly nitrogen fertilizers, are quickly decomposed by urease in the soil. This not only wastes a lot of nitrogen fertilizer resources, but also increases the cost of crop production, and brings a series of problems such as soil compaction and environmental pollution. The addition of urease inhibitor to nitrogen fertilizer is a new technology developed at the end of the last century. NBPT has the effect of inhibiting and slow release. On the one hand, it can effectively slow down the enzymatic hydrolysis process of nitrogen fertilizer into ammonia to reduce waste. And at the same time it can prolong the diffusion time of nitrogen fertilizer at the fertilization point, so that soil fertilization and crop fertilizer need can be synchronized. Thereby the effective utilization rate of nitrogen fertilizer increase by 30%~ 40%, and the fertilizer efficiency can be increased from 50 days to 120 days. It covers almost the entire growth period of the crop. It is completely possible not to use secondary top dressing. It is very effective for growing crops such as trees and corn.

As a soil nitrogen fertilizer inhibitor, NBPT is highly efficient, non-toxic and has no side effects on the soil. Moreover, NBPT naturally degrades into ammonia and phosphorus in the soil, and can also be absorbed as fertilizer by crop roots, and reduces the toxic effect of ammonia on seed germination and seedling growth. It is an excellent soil nitrogen fertilizer inhibitor.

The most important function of laser automatic welding machine is to use the laser beam with very high energy density as a heat source to achieve the welding effect. Generally speaking, the use of continuous laser beam can reflect the role of welding to better achieve good welding effect at the same time. Usually there are certain technological parameters for laser automatic welding machine. Then, what are the main process parameters of laser automatic welding machine with high quality and quantity?

1. The power density requirement of laser automatic welding machine:

Power density is one of the most important parameters of laser automatic welding machine. For example, high power density can heat the surface to boiling point in microsecond time and produce a lot of vaporization, which can make the precision welding and seamless welding of processing materials better.

2. Pulse waveform of laser automatic welding machine:

Pulse waveform of laser automatic welding machine is an important element for laser welding of thin sheet material. For example, when high intensity laser beam is applied to the surface of material to be welded, most of the reflectivity of metal surface will decrease and its reflectivity will change with the surface temperature. So we should pay attention to the change of metal reflectivity caused by laser pulse waveform in laser automatic welding machine.

3. Pulse width of laser automatic welding machine:

Pulse width of laser automatic welding machine is an important parameter to distinguish material of removal and melting in laser welding. It is also a key parameter to determine the cost and volume of processing equipment. This parameter is suitable for precision machining, and the general material can be neglected.

4. Defocus of laser automatic welding machine:

Defocusing is usually a process parameter that has an effect on the quality of laser automatic welding machine. In order to prevent the evaporation of holes caused by the high power density of the spot center at the laser focus, people should pay attention to the need for defocusing during laser welding.

The alumina abrasive having a microcrystalline structure obtained by the gel method is called the ceramic grains. Through special processing, each grain has thousands of tiny crystals. This structure brings the very good self-sharpness performance of the grains, which can continuously reveal new and sharp cutting edges.

RIKEN RMC Ceramic grains are very dense, rough, strong and sharp. When worn, they will produce a sharp cutting edge similar to the knife edge. Therefore, the ceramic grains will have a lower cutting temperature and lower burnt than the ordinary alumina when sanding hard to sand materials. It can be keeping sharpness for a long time with low loading. So that will bring you less total downtime and longer life.

Ceramic grains products could process into kinds of shapes, like belts, sand discs, sheets. The grains character decide that products have longer sanding life, higher cutting force and higher sanding efficiency performance.

Ceramic abrasive grain belts and sanding discs could bring you rapid cutting on difficult-to-sand materials such as aerospace, aerospace alloys and forged steel. The unique ability of ceramic abrasives increase production and reduces labor costs. RIKEN RMC Ceramic grains products also have a good performance in general sanding in auto repair, steamships, and aluminum alloys.

Ceramic abrasive is a new abrasive with microcrystalline structure prepared by gel sintering. It does not use smelting method and uses Al2O3 below 5 microns. In the presence of acid, some of the oxide is added to produce gelatin, which is made into granules. The raw material is strict, and the content of sodium oxide is less than 5%. It is characterized by non-smelting and crystallization within 3 microns.

Ceramic abrasives are hard and tough. Fine crystal shape can make Abrasives fall off regularly at different levels, make self-sharpening orderly, keep the sharpness of the whole abrasive, and have good processing effect.

Working conditions are equally important. Temperature and pressure are more important. Crystals are destroyed one by one to achieve self-sharpening.

It is first used to coat abrasives, which is 3-5 times higher than ordinary corundum (ordinary 100, zirconium corundum 207, ceramic abrasive 333).

At present, the world famous ceramic abrasives manufacturer include Saint-Gobain, 3M, Tebuck , VSM and Hermes. American 3M company is called "Cubitron", and its maximum crystallization is less than 3 micron.

Norton company is called SG abrasive, its crystal form is several microns; German Hermes company is called CB abrasive, its maximum crystallization is less than 5 microns. The crystal type of CX abrasive in Japan is called 1 micron, but in fact it is less than 3 micron.

Rotary dryer is mainly composed of rotary body, baffle, transmission device, supporting device and other components. Its working principle is to use the lifting plate with reasonable arrangement and alternate angle changes. The water-bearing material is thrown into the rotating cylinder, and the moisture is secreted from the material by hot air flow, and then the water vapor is discharged into the atmosphere for drying. Rotary dryer is used for drying slag, clay, limestone and other materials, mainly used in cement, chemical industry, metallurgy, building materials and other industries. The utility model has the advantages of large drying capacity, balanced operation, low energy consumption, convenient operation and high output.

The design of the protection system for the footsteps is the most important part of any Court sports tennis shoe.

Tennis is generally divided into hard ground, red clay, mud and grass. Tennis and basketball are more similar to the activities of the feet: strong force, variable direction, required impact resistance, good stability, good shock absorption, good slip resistance, but in contrast, tennis is more intense and faster.

Therefore, strength and court sports protection is the biggest design requirement for tennis shoes. The thickened suspension design of the insoles is also designed to improve the stability performance to meet the requirements of more jumping and shock absorption in sports. Some high-end products are also equipped with other special features. Shock-absorbing materials to reflect more professional sports style.

In addition to the importance of choosing shoes, it is necessary to have insoles - the opponents are flexible to start and retract. And you are stagnation, although you all have the same brand of shoes, in fact, the secret may be in the double indispensable insole. With a pair of "shallow cup insoles" with anti-slip and breathable sweat, it may be the secret of your invincibility.

The design of the protection system for the footsteps is the most important part of any tennis shoe. The protective effects of accessories such as basketball inserts", "hind cup", toe, hoop or mid-cushion not only make many "genius golfers" grow up in the tennis world, but also promote the creation of such things as "air cushions". Shock absorbers, "return pressure", "energy guide" and many other wonderful accessories. People pay more "manufacturing costs" to the accessories of these protection systems for the future of their own feet. But this is necessary and helpless.

Court sports insoles are primarily designed to absorb much of the impact shock that results from running and jumping repeatedly, especially on hard surfaces. In particular, insoles for court sports feature gel or foam padding at both the heel and under the ball-of-foot, the two parts of the foot that experience the most impact shock from running and jumping. Additionally, these insoles feature a built-in arch support to prevent your arches from collapsing under strain, and minor to moderate cushioning to alleviate pressure on the feet while standing and moving.

Pyroelectric sensor is a kind of sensor, also known as human body infrared sensor, used for life burglar alarm, visitor notification, etc., the principle is to release the charge through the amplifier into a voltage output.

The piezoelectric ceramic dielectric can maintain a polarization state after being polarized, which is called spontaneous polarization. Spontaneous polarization decreases with increasing temperature and the temperature drops to zero at the Curie point. Therefore, when the material is exposed to infrared radiation and the temperature rises, the surface charge will decrease, which is equivalent to releasing a part of the charge, so it is called pyroelectric. The discharged charge is converted to a voltage output by an amplifier. This is how the pyroelectric sensor works.

When the radiation continues to act on the pyroelectric element and its surface charge is balanced, the charge is no longer released. Therefore, the pyroelectric sensor cannot detect constant infrared radiation.

Working principle: The human body has a constant body temperature, generally at 37 degrees, so it will emit infrared rays with a specific wavelength of about 10UM. Passive infrared probes work by detecting infrared rays of about 10UM emitted by the human body. The 10 UM infrared rays emitted by the human body are enhanced by the Philippine filter and collected on the infrared sensing source. The infrared sensing source usually adopts a pyroelectric element, which loses the charge balance when receiving the temperature change of the infrared radiation of the human body, and discharges the charge outward, and the subsequent circuit can generate an alarm signal after being detected and processed.

Pyroelectric effect: When some crystals are heated, an equal number of oppositely charged charges will be produced across the crystal. This phenomenon of polarization due to thermal changes is called pyroelectric effect.

Fresnel lens: According to the Fresnel principle, the Fresnel lens is divided into two types: refractive and reflective. Its role is to focus and refract (reflect) the pyroelectric infrared signal on the PIR. Second, the detection area is divided into a number of bright areas and dark areas, so that moving objects entering the detection area can produce a modified pyroelectric infrared signal on the PIR in the form of temperature changes, so that the PIR can generate a change electrical signal. The sensitivity of the pyroelectric human body infrared sensor (PIR) is greatly increased.

Senba will keep offering human motion sensor module or infrared pir motion sensor module with high quality.
