Heavy goods vehicles – trucks, coaches and buses have been using

SCR technology and

AdBlue since 2004. For example, Mercedes and Volkswagen.



The latest Euro VI emissions regulations from the European Commission has really driven an explosion in SCR technology from the passenger car perspective in Europe. The Euro VI regs introduced in 2014/15 demanded nitrogen oxides emissions should be reduced by a whopping 56% compared to Euro V levels. For most diesel engines over 1.6L in capacity, AdBlue and SCR technology has been the only means to achieve this. So most new diesel engines over that size will feature an AdBlue tank from now on.

Reference News Network reported on October 8, Japanese media said that the global demand for industrial robots was driven by China. According to the International Federation of Robotics (IFR), Chinese sales in 2017 increased by 58%, setting a record of 138,000 units and accounting for more than 30% of the world. The labor shortage and the support policies of the Chinese government have played a catalytic role. China is setting off an unprecedented robot boom.

According to the report on October 8th by the Nihon Keizai Shimbun, according to the survey by Factory Network Asia, the total market share of Chinese local robot companies such as Shanghai Xinshida Robot (STEP) that owns

ADTECH is 31.7% as of 2017. Compared with only 26.2% in 2013, it has continued to rise slightly. However, the report also pointed out that in the field of industrial robots in the world, Japanese FANUC and Yaskawa Electric, Swiss ABB and the German KUKA acquired by China Midea Group is considered the world's top four. In China, overseas companies account for nearly 70% of the remaining. In the field of smart phones and home appliances, Chinese companies have surpassed Japanese companies in a short period of time, but there are still gaps in the field of robotics, including technical strength.

According to the report, in China, which is the largest market for industrial robots, local companies are gradually gaining strength. In related fields, the market share of local Chinese companies has exceeded 30% in 2017 and is slowly catching up with Japanese and European companies. What is the Chinese position as the "world's factory" in the field of robotics that influences international competitiveness of the manufacturing sector. "Japan Economic News" interviewed the heads of the two robot companies in Guangdong, China, and asked about the issues and prospects of Chinanese industrial production.

Through electronics factory tempering technology

Adtech is the largest manufacturer of horizontal multi-joint robots (

SCARA Robots) for electronic product assembly. Mr. Zeng Yiqiang, chairman of the company, pointed out that if you accumulate experience in electronic products factories such as personal computers, it is possible to catch up with Japan and Europe.

Reporter: In the field of robotics, Japanese and European companies are leading. What do you think for this?

Mr. Zeng Yiqiang: In terms of the durability of SCARA robots, ADTECH is temporarily behind Japanese companies such as Yamaha Engine and Seiko Epson. What we are better at is the ability to respond to meticulous needs. We have a dedicated team dedicated to tightening screws and welding processes and can be dispatched to our customers' factories. No overseas company can deal with it in such detail.

Reporter: How to narrow the quality gap with Japanese and European products?
Mr. Zeng Yiqiang: From the historical point of view, the overseas robot industry generally improves its strength by keeping pace with the country's automobile industry. Nowadays, the demand for electronic products factories such as personal computers and smart phones has also become the driving force for the development of the robot industry.
The electronics factory is concentrated in China. Companies like ADTECH can beat overseas companies if they can meet new demands and focus on R&D.
Labor costs rise to boost automation demand

The head of a company responsible for the development of robots in Dongguan pointed out that in order to cope with the increase in labor costs, the automation of the factory is indispensable.

Reporter: How many robots is running in the company?
Responsible person: There are 300~400 units, which will increase to 1000 units during the year. In order to use in the company factory, we started to develop robots in 2013 and started production and introduction in 2015.
Reporter: What is the reason for accelerating R&D and introduction of robots?
Responsible person: Because factories are hard to recruit workers, and labor costs are rising. The current labor costs have almost doubled than the costs in 2008. The number of employees is about 10,000, but when the delivery time of the circuit board of the new smartphone is approaching, there will be a shortage of about 3,000 people. These need to be offset by robot-based automation.

A.The magnetic pump works by.
The magnet pairs (n is an even number) are arranged and assembled on the inner and outer magnetic rotors of the magnetic actuator according to the law, so that the magnet parts are mutually formed into a fully coupled magnetic force system.The magnetic energy of the magnetic system is the lowest when the internal and external magnetic poles are opposite, i.e., the displacement angle Φ and 0 between the two magnetic poles, and the maximum is when the magnetic pole is rotated to the same pole, i.e., the displacement angle Φ and 2 π / n between the two magnetic poles.After removing the external force, because the magnetic poles of the magnetic system repel each other, the magnetic force will restore the magnet to the state of the lowest magnetic energy.The magnet then generates motion, which drives the magnetic rotor to rotate.
B.Selection step.
The status of magnetic pump production and magnetic materials, sliding bearing development, in order to ensure the quality of the project, in the selection of magnetic pump can refer to the following steps.
1. When the power of the pump is less than 10KW, select the magnetic pump to ensure the effect.
2. When the axial power of the pump is greater than 10KW or the medium temperature is higher than 100C, the domestic magnetic pump should be treated carefully, the material of magnetic steel and the structure of bearing material should be limited, and the shielded pump should be selected if necessary.
3. At present, the domestic

magnetic pump manufacturers are generally medium and small factories, the development and research means are relatively weak.Generally speaking, it is not suitable to entrust the manufacturer to research or develop the pumps beyond the parameters of the products in order to ensure the quality and progress of the project.The main domestic magnetic pump manufacturers and their products are listed in Table 1-1.
4. The quality of magnetic steel material is related to the service life, reliability and price of the pump. When ordering, the magnetic steel material, the supplier and its performance index should be made clear.The material and life of the sliding bearing should also be defined.
Operation cautions.
1. Preventing particles from entering.
(1) ferromagnetic impurities and particles shall not be allowed to enter the magnetic drive and bearing friction pair.
(2) after conveying the medium which is easy to crystallize or precipitate, flush in time (pour water into the pump cavity after stopping the pump, discharge clean after running 1min), the common problems about the fire pump in our country, in order to guarantee the service life of the sliding bearing.
(3) when conveying the medium containing solid particles, it should be filtered at the inlet of the flow pipe of the ZCQ type self-priming magnetic drive pump.
2. Prevention of demagnetization.
(1) the magnetic moment can not be designed to be too small.
(2) it should be operated under the specified temperature condition, and the medium temperature exceeding the standard is strictly prohibited.The platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump isolating sleeve to detect the temperature rise in the annular gap region so as to give an alarm or stop the machine when the temperature exceeds the limit.
3. Prevention of dry friction.
(1) No idling is allowed.
(2) medium extraction is strictly prohibited.
(3) when the outlet valve is closed, the pump shall not operate continuously for more than 2 minutes in case the magnetic actuator overheats and fails.
C.Compared with centrifugal pumps with mechanical or packing seals, magnetic pumps have the following characteristics.
1. The shaft of the pump is changed from dynamic seal to closed static seal, and the leakage of medium is avoided completely.
2. Without independent lubrication and cooling water, the energy consumption is reduced.
3. From coupling drive to synchronous drive, there is no contact and friction.The utility model has the advantages of low power consumption, high efficiency, and the damping and damping effect, which reduces the influence of the motor vibration on the pump and the influence of the cavitation vibration on the motor when the pump is subjected to cavitation vibration.
4. When overloaded, the inner and outer magnetic rotors are relatively slippage, which can protect the motor and pump.
D.Application of magnetic pump.

Magnetic pumps are widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television development, national defense and other departments to pump and deliver flammable, explosive, toxic and valuable liquids.It is an ideal pump for creating leak-free and pollution-free lamination workshop and lamination factory.

CNC tool is a cutting tool in machines processing

CNC tool classification
According to the tool structure can be divided into:
Integral: The tool is integrated, made of a blank, and is not separated;
Welded type: connected by welding method, divided into cutter head and arbor;
Machine clamp type: The machine clamp type can be divided into two types: non-indexing and indexable. Generally, the CNC tool adopts the machine clamp type.
Special types: such as composite tools, shock-absorbing tools, etc.

According to the materials used for manufacturing cutters, it can be divided into:
High speed steel cutting tools;
Carbide tools;
Diamond cutting tools;
Other cutting tools, such as cubic boron nitride cutting tools, ceramic cutters, etc.

From the cutting process can be divided into
Turning tools: divided into outer circle, inner hole, thread, cutting, grooving tool, etc.;
Drilling tools: including drill bits, reamers, taps, etc.;
Boring tool

Milling tools, etc.

How to choose CNC tools

When selecting tools for numerically controlled machine tools, the following aspects should be considered:

1. The types, specifications and Accuracy grades of CNC tools should meet the requirements of CNC lathe processing.

2. The precision is high. In order to meet the requirements of NC lathe for high precision and automatic tool change, the tool must have high precision.


3. Good chip breaking and chip removal performance. In cnc lathe machining, chip breaking and chip removal are not handled manually by ordinary machine tools. Chips are easily wound around the tool and workpiece, which can damage the tool and scratch the machined surface, and even cause injury and equipment accidents, affecting the processing quality and the safe operation of the machine tool. So the tool is required to have better chip breaking and chip removal performance.



Choosing a good woodworking tool is especially important for wood processing, especially in complex furniture processing.

1. First, you need to understand the equipment management and quality inspection of the manufacturer. The equipment used for production, the strictness of management and quality inspection have a great influence on the

wood router bit.

2. Check the appearance of wood router bit. observe whether the appearance of the woodworking knives is flawed, whether there is a small gap in the cutting edge of the woodworking knives, whether the knives of the woodworking knives are smooth, whether there are multiple faces and whether there are blunt edges at the cutting edges.

3.Measure the accuracy of the size of woodworking tools. Test the inner hole, size, outer diameter, shank diameter, etc.

4. Check the smoothness of the edge of the wood router bit.




battery separator plays a major role in lithium ion battery conduction lithium ions and isolation between the positive and negative electrode electronic contact. It is an important component to support the battery to complete the electrochemical process of charge and discharge.

battery Separator

In the use of lithium batteries, when the battery overcharge or at higher temperatures, the separator need to have enough thermal stability (thermal deformation temperature > 200 ℃), to effectively isolate the battery positive and negative electrode contact, prevent short circuit, such as thermal runaway and even explosion accidents. Currently widely used polyolefin Separator, its melting point and low softening temperature (< 165 ℃), it is difficult to effectively guarantee the safety of the battery, and its low porosity and low surface energy, limiting the battery performance ratio. Therefore, it is very important to develop

high safety high temperature Separator.

Lithium ion Battery Separator

Xiamen TOB technology research department has developed a new type of high temperature resistant porous membrane by adopting the wet process primary molding technology, which is low-cost to prepare and easy to quantify production. Preliminary study results show that thermal deformation temperature of the Separator is much higher than 200 ℃, and the thermal stability of the commercialization of non-woven Separator, can effectively guarantee the battery safety.

Although high-voltage lithium battery materials are getting more and more attention, these high-voltage anode materials are still unable to achieve good results in practical production and application. The biggest limiting factor is that the electrochemical stability window of the carbonate-based electrolyte is low. When the battery voltage reaches about 4.5(vs.Li/Li+), the

electrolyte begins to produce violent oxidation decomposition, causing the lithium-intercalation and lithium-deintercalation for the battery not working properly. The development of electrolytic liquid systems that can withstand high voltage is an important step to promote the application of this new material.

High-voltage Resistant Electrolyte

The development and application of new

high voltage electrolyte systems or high voltage film forming additives to improve the stability of electrode/electrolyte interface is an effective way to develop high voltage electrolyte. Economically, the latter is often preferred. Such additives to improve the voltage tolerance of electrolyte generally include boron, organic phosphorus, carbonates, sulfur, ionic liquids and other types of additives. Boron additives include trimethylalkanes borase, lithium borate dioxalate, lithium borate difluoroxalate, tetramethylborate, trimethyl borate and trimethylcyclotriboroxane. Organic phosphorus additives include phosphite esters, phosphite esters. Carbonate additives include fluorinated anhydryl compounds. Sulfur-containing additives include propionic acid lactone, dimethyl sulfonyl methane, trifluoromethyl phenyl sulfide, etc. Ionic liquid additives include imidazole and quaternary phosphate salts.

Electrolyte Supplier

According to the domestic and foreign studies that have been published, the introduction of high-voltage additives can make the electrolyte withstand the voltage of 4.4-4.5v. However, when the charging voltage reaches 4.8v or even more than 5V, it is necessary to develop the electrolyte that can withstand higher voltage.

The shelf life of AdBlue at different temperatures is as follows :


Storage Temperature(℃)

Shelf life (Month)










Test before use



It should be sealed immediately and not be used again if there is a strong smell of ammonia when opening the sealing cover of the storage tank,  it can be used after passing the relevant instrument test immediately.

(2) The storage container and filling equipment of AdBlue ;

AdBlue DEF will react with some materials, such as copper, iron, aluminum and so on. it will cause the deterioration if it is installed in the pot or the filling equipments of these materials, thus affecting the performance of SCR. So it have to use special equipment for filling AdBlue. In addition, AdBlue will crystallize at low temperature and its volume will expand by about 7%. Therefore, the storage

volume of AdBlue should be kept at about 90%.

(3)The storage and use environment of AdBlue should be cleaned.

In the process of using urea solution, we should try our best to avoid impurities from entering the solution and urea tanks. Generally, AdBlue have special tubes when refilling.
