The ternary ion polymerization technology uses the principle of electrostatic adsorption and plasma technology. It is an innovative technology for electrostatic precipitator on the market, which completely solves the problem of ozone exceeding the standard of electrostatic precipitator.

1. Non-corona, no ozone. The ternary ion polymerization purification technology, using DBD abnormal ion release protection, changes the corona process in traditional electrostatic dust removal, to prevent ozone from exceeding the standard.

2. Let "fine dust grow up", catch and adsorb. When the dust in the air passes through the ion channel of a strong electric field, a large number of energetic electrons make random movements, which impact and charge the fine dust particles molecules. The opposite charge attracts and generates condensation, forming large particles, which are affected by motion, gravity, and charge. Under the action of the potential electric field of positive and negative ions, it is captured and adsorbed by the microporous polymerizer when moving toward the anode or cathode. During the ion charging process of bacteria, the electronic structure is changed, thereby inhibiting the activity of the bacteria and playing a bactericidal role.

In addition, this technology is mostly used in high-clean environments such as aerospace and medical treatment, and is currently gradually entering the civilian field. As of 2012, the number of air purifiers using ternary ion polymerization purification technology has reached 3.5 million, of which 45% of the air purifiers in the United States have adopted this technology. In China, Mi air cleaners, Gunai fresh air systems, and Tianyu commercial fresh air systems have become the first industry pioneers to adopt this technology.

The ternary polymer lithium battery refers to a lithium battery that uses a nickel-cobalt-manganese oxide (Li(NiCoMn)O2) ternary cathode material as a cathode material, and a ternary composite cathode material precursor product that uses nickel salts, cobalt salts, and manganese salts As a raw material, the proportion of nickel, cobalt and manganese can be adjusted according to actual needs. The battery with a ternary material as a positive electrode is safer than a lithium cobalt oxide battery, but the voltage is too low, and it is used on mobile phones (the cut-off voltage of mobile phones is generally around 3.0V) ) There will be a noticeable lack of capacity.

The ternary polymer lithium battery refers to a lithium battery using a lithium nickel cobalt manganese ternary cathode material as the cathode material. There are many kinds of cathode materials for lithium ion batteries, mainly lithium cobalt oxide, lithium manganate, lithium nickel oxide, and ternary materials , Lithium iron phosphate, etc. At present, the battery cell of ternary material replaces the widely used lithium cobalt oxide battery cell and is widely used in the field of notebook batteries.

The material with relatively balanced capacity and safety has better cycle performance than normal lithium cobaltate. The nominal voltage in the early stage was only 3.5-3.6V due to technical reasons, which is limited in the scope of use, but up to now, with the formulation of Continuous improvement and structural improvement, the nominal voltage of the battery has reached 3.7V, and has reached or exceeded the level of lithium cobalt oxide battery in capacity.

The world's top five battery cell brands SANYO, PANASONIC, SONY, LG, and SAMSUNG have launched batteries of ternary materials. A considerable part of the notebook battery lines have replaced the previous lithium cobalt oxide batteries, SANYO, with batteries of ternary materials. In the aspect of SAMSUNG column batteries, the production of lithium cobalt oxide batteries has been completely shut down and the manufacture of ternary batteries has been completed. At present, most of the small high-rate power batteries at home and abroad use ternary cathode materials.

Ionic polymer refers to a type of polymer containing metal ions, with a specific gravity of 0.94~0.960. Softening point 35℃. It can be used continuously at 90℃ in air. The molecular structure is mainly composed of a copolymer of ethylene and methacrylic acid, on which metal ions are introduced. And use ionic bonds as crosslinks between molecules. Low crystallinity and good transparency. Rich in elongation and elasticity, both tensile strength and impact strength are high. High molecular weights can be used as thermoplastics, and low molecular weights can be used as adhesives and laminating resins. The film and plate made are insulating materials with very good performance. Adhesives can bond metals, glass, paper and plastics.

Ionic polymers are also known as ionomers and ionomers. It is a product obtained by introducing metal ions (such as sodium, potassium, zinc, magnesium, etc.) into the main chain of the copolymer of ethylene and acrylic acid monomers for crosslinking.

The ionomer currently used is a product made by introducing ethylene or methacrylic acid copolymer into sodium or zinc ions for crosslinking. The trade name is Surlyn. Due to the existence of ionic bonds in the main chain of the macromolecule, the polymer It has the physical characteristics of cross-linked macromolecules. It has high strength and toughness at normal temperature, but when heated to a certain temperature, the cross-linked chain formed by its metal ions can dissociate, which does not affect its melting process again, showing thermoplasticity. After cooling It can be cross-linked again, so it is a high-strength thermoplastic.

Ionic polymers are polymers that contain ionic bonds between chains. They are usually the sodium salt or zinc salt of ethylene methacrylic acid polymer or ethylene acrylic acid polymer, which undergoes polymerization reaction like LDPE under high temperature and high pressure, thereby forming a branched chain structure. The structural formula is shown below.

Ionic bonds have the effect of reversible crosslinking. When heated, the strong attraction between adjacent molecules weakens, causing the material to melt and flow. Upon cooling, this bond is re-established. The amount of acid on the polymer backbone generally accounts for 7% to 30% of its total weight. Not all acids can be neutralized to form salts. When the neutralization amount is generally between 15% and 80%, it affects the physical properties of the ionic polymer. The unneutralized acid provides a place for hydrogen bonding between adjacent molecules. These hydrogen bonds are weaker than the ionic bonds of salts, but stronger than ordinary secondary bonds. Increasing the amount of acid neutralization and the percentage of neutralization can enhance tensile strength, modulus, toughness, clarity, melt strength and oil resistance, but will reduce the melting point and tear resistance. Zinc-based ionomers have a wider viscosity range and lower hygroscopicity, while sodium-based ionomers have better chemical properties and grease resistance. [2]

Ionic polymers can also produce terpolymers containing acrylic acid, ethylene and methacrylic acid. Another ionic polymer is produced by saponification of ethylene alkyl acrylic acid copolymer, in which all acid groups are completely neutralized with sodium.

Ionic polymers have excellent melt strength, clarity, softness, strength and toughness. Even under low temperature conditions, it also exhibits superior impact performance and puncture resistance, making it an ideal material for making sharp items for skin packaging. It has a strong ability to absorb ultraviolet rays, thereby increasing the heating speed, and becomes another advantage for skin packaging. Its viscosity is good, especially after being soiled, it still has good heat sealing performance. It is widely used in vacuum packaging of meat products. Its excellent melt strength makes it suitable for deep pressing and thermoforming.

In addition, other applications of ionic polymers include cheese, fast food and pharmaceutical packaging. The acid-based neutralized ionic polymer has excellent aluminum foil adhesion, and is often used in heat-seal layers for extrusion-coated foil structures. [2]

Disadvantages of ionic polymers are: poor gas permeability and hygroscopicity, relatively speaking, the cost is higher than PE and EVA.
