1、Introduction:of the main product:

  1. Introduction of heavy ion microporous membrane

Heavy ion microporous membrane (track etched membrane) is a kind of filtering membrane with the prominent feature: uniform pore shape, smooth surface well-distributed pore size and cylindrical straight hole which is regarded as its unique feature . It is the feature that determines the heavy ion microporous membrane filtration can performance better than other membrane filters . The particles larger than the pores will be retained on the membrane surface while filtering. And the membrane is suitable to be used in cross flow or recoil, so as to improve the membrane lifetime. What’s more, the membrane is a kind of dielectric membrane, there is no pollution on the membrane itself, and it is an ideal tool for precision filtering and screening.

  1. Forming principle

Atom become ion after being stripped of electrons.The heavy ions which come from ion accelerator or nuclear reactors are used to bombard plastic membrane, resulting in damages on the membrane and leaving tracks on it.,and the tracks can expanded to form a diameter of micron and consistency microporous after being dealt with the chemical etching. Meanwhile, the pore size and pore density can be controlled strictly by technical method(0.01 ~ 15 um). And the membrane can perform well while filtering.

  1. 1 characteristics description::

3.1 the heavy ion membrane has the features of well shaped pore shape, cylindrical straight hole and uniform pore size.

    1. 1 transparent material, smooth and flat surface This kind of membrane is beneficial to collect and analyze particles by means of optical microscope, we can color the membrane directly without worrying about the membrane itself being dyed in the process of the microbial observation. So it can be used well in fluorescence analysis.
    2. 2 high filtering rateAlthough the porosity of heavy ion membrane (the ratio between the the area of pore size and the total area of the membrane) is not large, we can control the membrane thin enough (6 ~ 20 microns);

3.4 good intercept featureThe pore size of the heavy ion membrane is generally uniform,it can retain the particles larger than the pore on the membrane surface well, so it is benefit to separate particles .
3.5high mechanical strength, flexible The tensile strength of polycarbonate and polyester heavy ion membrane is more than 200 ㎏ /㎝ 2 , so it can be folded and reused without being damaged.

    1. light , consistency weight  Low water imbibition, less ash: light weight is 1 ㎎ / ㎝ 2, good consistency weight and low water imbibition, so it is benefit for quantitative analysis, Low water absorption avoid it from being bad because of damp surrounding;
    2. good chemical stability. Heavy ion membrane can resistant to acid and most organic solvents, good chemical stability .
    3. good thermostability. Heavy ion membrane can withstand high temperature 140 ℃, without affecting its performance, so it can be repeated thermal disinfection without cracks and deformation;
    4. good biological characteristics. Heavy ion membrane is neither antibacterial nor sterilization, nor erosion by microorganism. Bacteria, and cells are grown directly on the membrane filter when using appropriate medium,and it can work long time under humid conditions;
    5. others. The problems won’t happen in heavy ion membrane such as particles or fibers falling off . so it can’t pollute filtrate like other filters. It can be made for meeting different demands, for example, hydrophobic membrane (used for air pollution monitoring, etc.).hydrophilic membrane, black membrane and the membrane with grids on the surface,etc.

2.Product applications
1. Medical precision filters, precision filtering infusion apparatus
1.In the field of medical treatment, intravenous fluid therapy own characteristics of quick curative effect and simple operation.. Nowadays it is one of the most convenient clinical treatments. But intravenous fluids (injection) treatment will produce certain negative effects on the patients ,which can lead to cross infection and transfusion of the particles in infusion and then do a harm to human body.The only way to prevent particle hazard is to use precision infusion. There is an obviously different when comparing to the general infusion with 15 um pore size, all the heavy ion microporous membranes produced in nanyanghuitong are adopted the membrane with 5 um pore size( national standard).for using as the filter medium in precision infusion ;the total effective rate of insoluble particles can reach 98% or more, which make sure the patients safety while taking the venous transfusion treatment.

2. The applications in other fields

1 biological scientific

The heavy ion microporous membrane has good optical performance, the membrane with different pore sizes can be used to separate the bacteria or cells, and we can observe it under the microscope directly ,which can greatly improve the accuracy and efficiency.


2 analysis and test in the field of environment, and petrochemical industry

Taking advantage of its consistence pore size, nuclear pore membrane has become the analysis test standard membrane.


3 remove the yeast in brewing industry

The yeast can be removed completely by using the membrane with 0.5~0.8μm pore size in the process of final filtration. So the membrane can be used in beer 、wine filtration ,and so as to protect the product from deteriorating and also make sure of the high quality.


4 sterile control of medicine, biological products

Almost all the bacteria can be removed by using the membrane with 0.4um pore size. besides ,the membrane belongs to the inert material which is able to withstand the disinfection with known methods. Therefore ,heavy ion microporous membrane is the best choice in sterile controlling.


5 aseptic control in beverage industry

6 preparation of electronic ultrapure water

The particles larger than 0.45um and all the bacteria can be removed by the membrane with the 0.4 um pore size.and no any impurities can release in the filtrate separation, so it is the ideal material in terminal filtration.

The forest experts in South Korea take use of the cellulose which is extracted from trees to prepare the lithium battery diaphragm

According to the power portal on June 28th, 2013 The forest expert Dr. Lee Xianying who was in the South Korean academy of national forest claimed that , lithium battery diaphragm could be made from the cellulose which was extracted from trees. and then developed an isolation membrane technology successfully by extracting the core material for the lithium battery form the main chemical composition cellulose in trees.
Lee said, transformed cellulose to cellulose fiber with the size 20~30nm by mechanical method, and then mixed organic solvent and water mixture with a certain ratio and thickness to produce cellulose nano paper isolation membrane. The lithium ion in the separation membrane of cellulose paper had excellent conductivity and electrochemical security, it would not shrink at high temperature, so it can be used in a variety of electrolyte. Dr. Lee said :”it is the trait of cellulose that make sure high quality lithium ion battery can be made successfully ” It was said that, nowadays, most of the lithium ion battery separation membrane adopts oil olefin resin which is made of polyethylene and polypropylene. Forest academy said: "it has a great significance in the scientific level for adopting the environmental protection material which can be obtained easily from trees for producing isolation membrane.
According to forest academy , by 2012,the global marketing scale of the core materials in the lithium ion battery isolation membrane can be up to 200 billion KRW they hope there will be a significant market share after the research result is carried out. .


News 3:

Water purification equipment industry will enter a consolidation period ,and ten years later, the marketing scale would exceed one hundred billion.

  According to Beijing business network on June 20th, 2013: Reporter visited several home appliance stores in capital recently and found that the water purification equipments have changed from the past water dispenser、water filter bucket to water purifiers, and the marketing share of water dispenser increase the most obviously. In the eyes of Experts , in the following 10 years, the domestic marketing scale will excess billions as consumers safety consciousness on the water quality increase ,water purification equipment industry will also enter the integration phase. And the water filter bucket will be eliminated gradually..
"Both don't exist any comparability" water purifier salesman told reporters,nowadays,water purifiers and water dispensers have almost replaced for the water filter bucket, Even if the cheapest water purifier worth 2000 RMB ,which is much better than water filter bucket. In terms of price, net bucket need to be used together with the water dispenser , although both worth less than 1000RMB, there have been no marketing competitiveness completely.
While visiting the home appliance stores, the reporter found that, there were three kinds of water purification equipment sold on the market,water filter bucket, water dispensers and water purifiers, in which the water filter bucket was the earliest water purification equipment on the market ,with low price and poor effect on water purification.
As consumers’ demand for water quality increase, the water filter bucket with the poor water purification is facing the embarrassment of being eliminated by the market. To avoid suffering the loss, enterprises have also made a strategic adjustment and reduce or stop the production of water filter bucket . The related man in charge in Qinyuan Water Purification Equipment said that they would not sell the water filter bucket after the stocks sold out. and in future they would take water purifiers as the main product, and changed all the production lines about water filter buckets and water dispensers for water purifiers.
Daily Chemical companies penetrate into the water purifier marketing
After the Midea, Haier, Sun etc,such traditional home appliance enterprises entered water purifier marketing, the Daily Chemical companies like Unilever announced to enter the water purification market last month, and would launch a product named“Unilever water purifiers”on July 1st .According to the relevant data, recently,the brands of domestic water purifiers have more than 4000. The experts said that the main reason was just because everyone was bullish on the China’s marketing prospect for water purification equipments .
According to the research data, it shows that ,in the domestic marketing share for the drinking water, bottled water accounts for 75%, traditional boiling water takes up 22%, and water purification equipment market share is only 3%.. It is predicted that the situation will be totally reversed after 10 years, water purification market share will reach 75%,. And the marketing scale in the future will be more than 500 billion RMB if the price is 2000RMB per set and every 4 people consist of a family. Strong marketing space will derive a strong marketing competitiveness for sure. In the opinion of the experts, the water purification equipment companies who have the technology and innovation brand and channel will be survived in future. And the daily chemical companies like Unilever and some small and medium-sized water purification equipment companies are more likely to be eliminated by the marketing. As a kind of small home appliance products, water purification equipment has the property of electrical appliances products, channels and after-sales are very important, but these two aspects for the small and medium-sized enterprises and cross-border enterprises are very difficult to be dealt well ,so it’s hard for the companies to .cover the marketing completely.
Modular products will become the mainstay in future
Reporter found that nowadays, the water purifiers with the characteristic of assembly become the must-haves gradually in the water purification equipments. During the Dragon Boat Festival, compared to the water dispensers and water filter buckets , water purifiers had the greatest sales promotion. A kind of water purifier worth 2598 RMB was sold only 1799RMB with two sets of filters worth hundreds of RMB as a complimentary. The main reason why the modular products are so popular because its good performance like water purifiers and convenience like water dispensers. Some insiders point out , as more and more consumers concern about the water quality and the water purification equipments have been accepted by the consumers who live in the first-tier cities. But for these consumers,they also have high requirements on the convenience of product,that’s why water purifiers come out. But in the opinion of Hong Shibin who is the executive director in the Association of Chinese Home Appliance Business Marketing Committee , no matter what kind of water purification equipment, as the companies who engage in water purification equipment increase, and the market competition is fierce, only those popular and famous products can be survival. But now the most important thing is how to cultivate the market, and promote the imagine of water purification equipments in consumers’ mind, less than 5% penetration rate is still the primary problem in the development of water purification equipment.
