The purpose of developing high technology is to make it serve human better. Lithium-ion batteries have developed rapidly since 1990 because of their excellent performance and they have been widely used in society. Lithium-ion batteries have rapidly occupied many fields with incomparable advantages over other batteries. As we all know, mobile phones, laptops, small cameras and so on all involve the application and development prospect of lithium battery, and more and more countries use the batteries for military purposes. The application shows that lithium battery is an ideal small green power supply.

The application and development prospect of lithium battery will expand rapidly in the next five years. The application and development prospect of lithium battery is mainly divided into three parts: consumer electronic products, electric vehicles and industrial energy storage. We can find that application focus of lithium batteries is at the stage of development from small batteries market of consumer electronic products to power batteries market of electric vehicles and industrial energy storage. The order is: consumer electronic products market electric vehicles market industrial energy storage market.

In emerging markets such as tablets, electric vehicles (PHEV + EV) and home energy storage, some lithium-ion batteries are the best choice, while others are the first choice. In the market of power grid energy storage which has not yet arisen, the related demonstration operation projects have been carried out at present.

Lithium-ion batteries are gaining ground in the market mainly because of their rapidly declining prices. In terms of performance, lithium-ion batteries are superior to lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries and other major competitors. Through the advantages of performance, lithium-ion batteries gradually expand the market scale. The growth of demand directly leads to the expansion of production capacity and the reduction of manufacturing costs, which in turn stimulates further growth of market demand. In this way, the lithium battery application industry has embarked on a virtuous cycle of development.

Particle size measurement using static light scattering

The particle size distribution as a parameter to specify a powder or dispersion plays a central role in many applications. Examples are construction material (sands, cements), pharmaceutical development, lime stones, ceramics, colored pigments, fertilizers, emulsions and may more. The range of applications is increasing permanently and hence the requirements on the measurement methods regarding size range, measuring time and reproducibility. Particularly the precise and reproducible detection of particles with sizes close to the measuring range limits as well as the simultaneous determination of particle sizes of very small particles (nanometer range) as well as large particles (lower millimeter range) for the characterization of polymodally or very broadly distributed samples provides a challenge. State-of-the-art laser diffraction devices such as the  particle size analyzer for sale solve these tasks by an innovative design of the optical bench for the detection of backscattered light of very small particles and by detecting large particles by an integrated high-speed CCD camera or the combination of static light scattering and Automated Imaging.

Measuring method
In static light scattering laser light (monochromatic, coherent light) interacts with the particles, which have to be characterized in terms of particle size. In dependence of the particles'size, the light waves are scattered by the particles in a characteristic manner: the larger the particles are, the greater is the scattering in forward direction. With particles smaller about 100 nm, the scattering intensity is nearly identical in all directions.

The scattering intensity is determined by stationary detectors depending on the angle (light scattering intensity distribution). State-of-the-art laser diffraction systems such as the Bettersizer S3 Plus guarantee the determination of scattering intensities in a continuous angular range of 0.02 – 165°, i. e. in forward, side and backward direction. This is achieved by means of a so-called double lens design and oblique incidence optical system (DLOIOS technology): Fourier lenses (collective lens) are positioned between the laser and particles as well as between particles and detectors. The particles will interact with the light within a parallel laser beam. This offers the advantage that the scattered light can also be detected at very large angles (in backward scattering direction) and thus even very small particles can be measured precisely. Thanks to DLOIOS technology, the problems of conventional measurement setups can also be avoided. Therefore, neither the suitable lenses for the corresponding particle size measurement range have to be selected prior to the measurement (in comparison to the Fourier optics), nor do measurement inaccuracies result from different particle to detector distances, if not all particles lie in one plane (in comparison to the inverse Fourier optics).

To calculate the particle size distribution from the measured scattering spectra, the theory of either FRAUNHOFER or MIE is applied. The FRAUNHOFER theory is based on the hypothesis of opaque and spherical particles: the scattered pattern corresponds to a thin opaque two-dimensional plate – diffraction only occurs at the edges. Therefore no additional optical input constants of the material are necessary for this calculation. However, this theory is only suitable for mean particle sizes from approx. 5 µm.

In contrast the MIE theory uses the hypothesis of virtually translucent and spherical particles, meaning that the light permeates the matter and is scattered elastically at the atoms of the particle. The knowledge of the complex refractive index of the particles and the liquid as well is necessary. This theory is applicable for particles of all sizes.

The following figure shows an example of a volume-related particle size distribution of a calcium carbonate powder – measured with a Bettersizer S3 Plus.

SOY SAUCE

Soy sauce being eight kinds of amino acid and trace elements is an essential component of human nutrition and health. Due to the application of traditional technique, the long existing problem of secondary sediment of soy sauce which has caused poor appearance, especially finished goods soy sauce on the shelves needs to be solved.

Ceramic sauce membrane separation technology had been extensively used in food and fermentation fields. For example, it is used in the production of apple cider vinegar. This technology used as a substitute for heating, removing thallium and turbidity. It can remove heat-resistant bacteria; keep soy sauce from perishing based on retaining original flavor and save the previous process of diatomite filtration. It also can discolor in order to make from white soy sauce to meet people’s requirements. Heat and oxygen stability of soy sauce after discoloring are been notably improved while containing Fe, Mn and Zn will reduce.

Ceramic membrane is used for clarifying soy sauce. The raw soy sauce is cooked, large particles are removed by sedimentation, and the supernatant filtered through the ceramic membrane. Ceramic membrane filtration does not alter the general composition of soy sauce, but significantly reduces turbidity and count of aerobic microorganisms in the product.

• Long and reliable lifetime

 VINEGAR

The beneficial action of vinegar (white, rosé and red) on the human body has long been known, right since it was used not only as a food but also for medicinal and anti-contamination purposes. In recent years some medical researchers have highlighted the importance of vinegar in the diet, in that it favors the stabilization of certain nutritional components in food.

Vinegar is made from the oxidation of ethanol in wine, cider, fermented fruit juices and/or other liquids containing alcohol.

Filtration is essential to clarify vinegar in view of present production method, micron and submicron suspended particles come into being and polymerize after treating some vinegar with traditional filter way.

Inorganic ceramic membrane filtration technology based on the principle of physical separation display the obvious specialty. Ceramic membranes and their application in filtering and separating china-style vinegar have the advantages over the polymeric membrane and other traditional filters.

Table vinegar passes through the membrane filtration surface; permeate composed of organic acid and matters to form vinegar and ester fragrance in the table vinegar flows through the membrane tangentially, the retentate, micron, and submicron suspended particles, macromolecular protein, and microorganism moves through the membrane. The separation is driven by the pressure difference from one side of the membrane to the other –referred to as transmembrane pressure. A filtration cycle can’t end until the retentate comes up to a certain concentration. Ceramic membrane separation installation is ideally suited to CIP pressure back pulsing in order to keep a stable membrane flux.

Advantages:

• Obtaining a clear filtrate, improving transparency clarity
• The turbidity of permeate is the range of 0.2~0.5NTU
• No discharge of filter aids
• To prevent from the secondary precipitate
• To keep original saline matter, amino acid, total acidity, reducing sugar and other effective ingredients
• To remove bacteria, macromolecular organically matter, suspended solids and some poisonous matters
• To get a bright tint, a sterling fragrance, have no change of non-volatile acid and soluble non-salt solids content
• To substitute the raw vinegar to all the traditional clarification operations (collage, decantation, diatoms filtration, plates, and polymer membranes)
• The chain and technologic time are so considerably shorten
• Low operation cost, compact, maintain conveniently

Basic information

This sustaining valve is opened to prevent the pipeline and equipment from being damaged due to overpressure when the pressure in the water supply pipeline exceeds the set pressure of pressure relief. The valve closes automatically when pressure drops to the set value. 

Features

1. Accurate Pressure Control

2. Fast Opening to Maintain Line Pressure

3. Slow Closing to Prevents Surges

4. Completely Automatic Operation

Principle

Inlet pressure water enters the lower cavity of the pilot valve diaphragm from the guide valve when the pressure in the pipeline exceeds the set pressure of the guide valve to make its pressure increase to open the guide valve, the main valve control room outwards drain under the effect of the inlet pressure water to open the main valve, it starts to discharge pressure. When the pressure in the pipeline drops to the set pressure, the pressure in the lower cavity of the guide valve diaphragm decreases, causing the guide valve closed. This results in increased water pressure from the guide pipe to the pilot valve, then to the main valve control room. The main valve plate closes and begins to hold pressure. 

Installation and Commissioning

The pressure relief(sustaining) valve supports horizontal and vertical installation but should pay attention to the inlet and outlet direction of valve body water when installing. In general, one fire water supply system can only install one pressure relief valve . Within the operating pressure range of the spring specified in the nameplate, the opening pressure can be adjusted by rotating the adjusting screw to change the spring compression amount. For specific use, please consult ZhengFeng Valve Group.

Double regulating valve working principle

Balance valve is a dynamic and static balancing valve under hydraulic conditions. Such as static balance valve, dynamic balance valve.

Valve body material: cast iron, cast steel,

Work pressure is 0.6-4.0 MPA.

The working temperature is - 5 C - 350 C.

Valve caliber DN15-DN300,

Connection mode: flange, internal thread,

Driving mode: manual and electric.

Manufacturing standard: national standard.

Balancing valve is a special function valve. It has good flow characteristics. Besides, it has valve opening index, opening locking device and pressure measuring valve for flow measurement. By using special intelligent instrument, the flow value flowing through the balance valve can be directly displayed by inputting the valve type and opening value according to the measured pressure difference signal. As long as the balance valve with appropriate specifications is installed in each branch and user's entrance and debugged once with the special intelligent instrument, the flow rate of each user can reach the set value.

Static balancing valves are also called balancing valves, manual balancing valves, digital locking balancing valves, double-position regulating valves, etc. It is through changing the clearance between the spool and the seat (opening), to change the flow resistance through the valve in order to achieve the purpose of regulating flow. Its object of action is the resistance of the system, which can distribute the new water in proportion to the design calculation, increase and decrease the branches in proportion at the same time, still meet the flow demand of part of the load under the current climate needs, and play the role of heat balance. Dynamic balancing valves are divided into dynamic flow balancing valves, dynamic differential pressure balancing valves, self-operated differential pressure control valves and so on.

Dynamic flow balance valve is also called self-operated flow control valve, self-operated balance valve, constant flow valve, automatic balance valve, etc. It automatically changes the drag coefficient according to the change of system working condition (differential pressure). In a certain range of pressure difference, the flow through can be effectively controlled to maintain a constant value, that is, when the pressure difference before and after the valve increases, the flow through the valve can be maintained by the action of automatic closing small. On the contrary, when the pressure difference decreases, the valve opens automatically and the flow rate remains constant. However, when the pressure difference is smaller or larger than the normal working range of the valve, it can not provide additional pressure head after all. At this time, the flow rate of the valve to the full open or closed position is still lower or higher than the set flow rate can not be controlled.

Dynamic differential pressure balancing valve, also known as self-operated differential pressure control valve, differential pressure controller, constant voltage variable synchronizer, differential pressure balancing valve, etc. It uses differential pressure to adjust the opening of the valve, and uses the change of pressure drop of the valve core to compensate for the change of pipeline resistance, so as to keep the differential pressure basically unchanged when the working condition changes. Its principle is that in a certain flow range, it can effectively control the constant pressure difference of the controlled system, that is, when the pressure difference of the system increases, it can ensure that the pressure difference of the controlled system increases by automatically closing the valve. When the pressure difference decreases, the valve opens automatically, and the pressure difference remains constant. The self-operated pressure difference control valve has an automatic plug closing state within the control range. The pressure difference between the two ends of the valve exceeds the preset value. The plug opens automatically and adjusts the opening automatically under the action of the pressure sensitive film to keep the pressure difference between the two ends of the valve relatively constant.

The lithium battery advantages are large capacity and high working voltage. The capacity is twice as large as that of the same nickel-cadmium battery, which is more suitable for long-term communication. The voltage of lithium ion is 3.6v, which is three times as high as that of nickel-cadmium and nickel-hydrogen batteries. Charge retention ability is strong, allowing a wide range of operating temperature. After 30 days of storage in open circuit mode at (20 +5) (?) C, the discharge capacity of lithium-ion batteries at room temperature is more than 85% of the rated capacity. Lithium-ion batteries have excellent discharge performance at high and low temperatures, and can work at - 20 ~+55 (?) C. The discharge performance at high temperature is better than that of other batteries.

Long cycle life. Carbon anode is used in lithium-ion batteries. During charging and discharging, the carbon anode will not produce dendritic lithium, which can avoid damage to the inner dendritic lithium short-circuit ears of batteries. After 1200 consecutive charges and discharges, the capacity of the battery is still not less than 60% of the rated value, which is much higher than other types of batteries and has long-term economic use.

It has high safety and can charge and discharge safely and quickly. Compared with metal lithium batteries, lithium-ion batteries have the characteristics of short circuit resistance, overcharge resistance, overdischarge resistance, impact resistance (10 kg weight falling freely from 1 m height), anti-vibration, shooting, needling (penetration), non-fire and non-explosion. Because its anode uses special carbon electrode instead of metal lithium electrode, it allows rapid discharge and can charge and discharge at a charge rate of 1c. So the security performance is greatly improved.

No environmental pollution. Batteries do not contain harmful substances such as cadmium, lead and mercury, which is a clean "green" chemical energy without memory effect. It can be repeatedly charged and discharged at any time. Especially in emergencies, it shows excellent performance.

It has small volume, light weight and high specific energy. Usually, the specific energy of lithium ion batteries can be more than twice that of nickel-cadmium batteries. Compared with the same capacity nickel-cadmium batteries, the volume and weight of lithium ion batteries can be reduced by 30% and 50%, which is conducive to the miniaturization and lightweight of convenient electronic equipment.

Nano-particle Size Analyzer

We all agreed that we should buy projectors. After all, for young people who rent a house, the projector can not only achieve all purposes of the television, but also it is easy to carry with small space. Of course we should choose a projector.

However, for a family, what should they choose? TV or projectors? What are the advantages and disadvantages of multimedia projector?

Screen size

The most obvious difference between the projector and the TV is the projection screen. From the perspective of screen, whether it is a mobile phone or a TV, people are pursuing a large screen size.

Projectors are basically 100 inches or 200 inches start, and the size can be adjusted according to their own needs , but  80 inches television now is seldom to be seen.

Projectors win once

Floor space
