It has been ten years since the ban on free plastic bags was promulgated in China in 2007. This regulation has significantly reduced the use of plastic bags to some extent, but with the rapid development of express industry and food delivery in the recent years, the number of plastic bags is booming again. While platic bags provide convenience to consumers, they can also cause serious environmental pollution because of excessive usage, inadequate recycling and other reasons. Therefore, the ban on free plastic bags cannot settle all these issues, and we should pay attention to some greener products. PLA and some other high polymers are biodegradable and environmental friendly materials, and now they can be used to replace the traditional PE plastic packing bags. PLA, also known as polylactic acid, is a new biodegradable and bioactive thermoplastic aliphatic polyester derived from starch of renewable resources, such as rice straw, wheat-straw and so on. The starch will turn into glucose by saccharification, and then the glucose and microbial strain can become high purity lactic acid by fermentation, and at last the polylactic acid can be made by chemical polymerization. Due to the good biodegradability, PLA is a green material which can be degraded by the microorganism and finally produce CO2 and water. Besides, it is also very safe to use and will not release toxic gases such as nitrides and sulfides when incinerated. With the above advantages, PLA can be widely used in various fields, such as packaging (packing bag, packaging film, medical film, foamed plastics), textile, medical treatment, 3D Printing and other durable goods(electronic field, auto spare parts, etc). Therefore, the polylactic acid can be an ideal substitute for the traditional PE plastic materials and can work together with the ban on free plastic bags to protect the environment.
China Pingmei Shenma Group announced on July 13, that the second stage of the 3,000 MT silane gas project cooperated with Shanghai Jiaotong University had been put into trial production since June 25. At present, the production is stable and the purity of product has reached to 99.999999%. In October 2014, the first phase of the production ran successfully with an annual capacity of 600 tons and the purity of silane gas reaching to 8N. After that, the second phase with an annual capacity of 3,000 tons was put into construction in July 2016. With the annual capacity of 3,600 tons, and the domestic market share of about 40%, the project marks the end of the domestic demand of high-purity silanes completely dependent on imports. It is said that the company will invest 2 billion yuan to build the third-phase project with an annual output of 15,000 tons of high-purity silane gas, 1,500 tons of electronic-grade polysilicon and 1,000 tons of zone melting polysilicon. Last year, the total amount of chip imports in China's IC industry reached $230 billion. One of the most important reasons is the lack of high-purity crystalline silicon materials, which are highly based on high-purity silanes. The project will contribute to China's IC industry and the reallocation of market share.
Recently, the environmental pollution has become a hot issue in the chemical industry and many chemical factories have been forced to stop production. Efficient, easy-to-use and low-cost cleaning products are favored by the market. As a high-performance photocatalytic material, nano-TiO2 is one of the main research directions of sewage treatment agents. It is a kind of semiconductor material that can induce photo-oxidation and reduction reactions under the action of light. Being a high-efficiency sewage treatment, TiO2 can destroy the bacteria and viral protein, thereby degrading pollutants and purifying the water. Moreover, nano-TiO2 can treat pollutants such as phenols, halogenated hydrocarbons and heterocyclic compounds effectively. When the researchers sprayed TiO2 photocatalyst onto stainless steel, it turned out that the amount of organic carbon in the wastewater had been significantly reduced, and had obvious decolorizing effect for the wastewater from tannery. Another research studied the feasibility of nano-TiO2 combined with γ-irradiation in the treatment of papermaking wastewater. The results show that the combination can significantly improve the cleaning effect on wastewater. On the aspects of air purification, TiO2 can effectively degrade the indoor and outdoor organic pollutants, oxidize and remove oxychlorides, sulfides and various odors in the atmosphere. Besides that, TiO2 can also degrade harmful gases such as HCHO, hydrogen sulfide, ammonia, etc.
Ethylene glycol, a widely-used chemical product, has been playing an important role in our daily life since its first appearance in 1859. Though the ethylene glycol usually appears in the production of those commodities like synthetic fiber and cosmetics etc., it has also left many indelible imprints in the history of civil aviation. The Most Popular Aircraft Deicing Fluid To ensure a safe flight in the freezing weather, deicing is an indispensable step before the big machine takes off in winter. Skipping this procedure will cause severe consequences. On December 27 1991, the Scandinavian Airlines Flight 751 planning to fly from Stockholm Arlanda Airport to Copenhagen, made an emergency landing in a woods located 15 kilometers to the east of the airport one and a half minutes after it took off due to a big engine failure. 92 passengers were injured in this accident. The root cause for the engine failure to this MD-81 plane is exactly an inadequate deicing procedure. After the Scandinavian Airlines Flight 751 had blasted off, the ice shed and caused an engine surge. However, passengers on the American Eagle Flight 4184 were not so lucky as those on Scandinavian Airlines Flight 751. Flying from Indianapolis to Chicago, the plane crashed on a farmland of Roselawn, Canada, because of losing control caused by the icing and the poor communication about the newly installed system between manufacturer and airline company. All the 68 passengers died in this disaster. Therefore, deicing is an important job and the deicing fluids are absolutely necessary. The most common ones include methanol, ethanol and ethylene glycol. Due to its lowest ice point and best performance, and other advantages like good chemical stability, lower price and higher safety, ethylene glycol has become the first choice for many airline companies. The Most Dangerous Material for PET Insulation Ethylene glycol plays an important role in deicing and the air safety, but the PET material made of it can be a nightmare of civil aviation. On September 2, 1998, Swissair Flight 111 flying from New York to Geneva broke out a fire in the air and crashed in the sea near to the Halifax Airport of Canada. All the 229 people on board died in the crash. After that, CATSA spent four and a half years and $40 millions in the investigation, and discovered that the crime culprit in this accident was a small electric wire which caused the fire but the PET thermal baffle nearby speeded up the spread of the fire. Since then the PET thermal baffles were banned on the aircaraft, and this material had disappeared in the civil aviation. Therefore, the commonly seen ethylene glycol can have unimaginable impacts in our daily life and the power of chemicals cannot be ignored by any of us. Plane, as one of the safest transportation method, still have a space for improvement. No matter it was the emergency landing of Sichuan Airline flight caused by windshield crack, or the rapid decline of Air China flight, the discussions about the air safety were heated on the Internet. It is expected that the development of chemical industry can contribute to the civil aviation and make the plane travel a better experience.
Plastic is commonly used in our daily life due to its convenience and lower cost. However, it is difficult to degrade and may cause severe pollutions to the earth. Now thanks to professor Yu Long, the director of Sino-Singapore International Joint Research Institute, plastic has became a new edible material. He is recognized as the “starchman” in the industry, because he has been working on various polymeric materials from renewable resources and has successfully made the starch-based plastics. In his early research, Prof. Yu has successfully developed and commercialized many starch-based products, including the pure starch-based biodegradable plastic packaging materials and the medicine capsules. And in recent years, he has developed pure starch-based biodegradable cushion packaging materials for the express delivery(foam). Along with the development of the Chinese express delivery industry, cushion packaging material is widely used in the delivery process. However, petroleum-based plastic foam can cause great harm to the environment. The pure starch-based, biodegradable and environmental-friendly cushion packaging products produced by the special technology and processing equipment developed by Prof. Yu can not only greatly reduce the transportation and storage costs, but also be used as the animal feed or children’s toys, due to the safe starch materials.
On July 9, 2018, Starbucks, the largest coffee chain shop in the world announced that they would completely discontinue using plastic straw after 2022. This news caused a big shock in the whole world. According to the investigation, humankind consumes about 500 million plastic straws every year. As it’s an act that may contribute to the environmental protection, many others brands like Ikea, MacDonald are also trying to stop using the plastic straws. However, abandoning the most commonly used plastic straw means we have to find some other substitues. Besides the cup lid for direct drinking, the most anticipated alternatives is the paper straw. Compared with the plastic straw, the paper one has their own advantages: I Paper straw is much more degradable Plastic is such a basic material in our daily life that most of us cannot imagine our life without it. However, while we are enjoying the convenience that plastic brings to us, we also have to recognize the environmental pollutions caused by this material. Plastic is difficult to degrade, and most plastic products will eventually enter to the ocean, causing serious water pollution and killing marine life. That´s why we need the paper straw which can be degraded in 3 to 4 months buried in earth. II Paper straw can be more beautiful The plastic straw is usually transparent, white, striped and just has one single color. But the paper one has many different design and can be much more beautiful. Paper is a material easy to color, and pigments can show a perfect status on the paper. For some restaurants, a good looking paper straw can even increase their sales. But each coin has two sides, so the paper straw also has its disadvanteges: Its cost is higher than plastic straw Due to the mature technology and market, the plastic straw can be produced at lower cost than the paper one. To product a qualified paper straw and make it last in water for a longer time, those manufacturers have to add more additives. That’s why the plastic straw is more competitive in the market. Companies always want to spend the lesat amount of money to earn the most profit, so the cheaper plastic straw is obviously a better choice. Therefore, it may take some time before the paper straw can be popularized. Before that the plastic straw will still dominate the market. However, those companies in the paper making industry will have a big opportunity to develop themselves.
At present, China has issued several government documents for the IC industry, including "The Outline for the Promotion of the National IC Industry Development" and "Made in China 2025", and has promised to offer fiscal preferential policies to the IC industry, which confirm the goal to develop an international IC brand. In view of the fast growth of the domestic IC industry, demand of electronic chemicals may expect a rapid growth. Electronic chemicals related to IC industry include silicon wafers, electronic gases, wet chemicals, photoresist, etc. According to the IHS markit report, the market size of China's IC supporting electronic chemicals in 2017 is about 2.2 billion dollars among which the largest market is silicon wafers, accounting for 32%, followed by electronic gas (23%). According to statistics, the electronic chemicals mentioned above have an annual growth of over 10%. At present, large international companies has occupied the main shares of the domestic market, and most high technology products are highly dependent on imports. However, in recent years, with the support of government, some domestic enterprises have made breakthroughs in the industry. Take Jiangfeng Electronics as an example, it has changed the situation of total dependence on imports for semiconductor targets, and has brought its products to the international market. In the next few years, China will continue to develop the IC supporting chemical industry, narrow the gap with advanced companies, and enhance its own supporting capabilities.
Because of the rising and fluctuating trend of the crude oil and the stringent environmental supervision, the chemical market in the first half of 2018 has not continued major rising trend of last year. According to the statistics, the prices of 98 principal chemical products have fallen down evidently. However, the hexanediamine has hit the record and increased dramatically by 147.3%. According to the insiders, the soaring price of hexanediamine is highly related to the high price of the crude oil, the production halt of foreign magnate and the sharp increase of the downstream demand. Firstly, the high price of international crude oil The hexanediamine is made of hexanedinitrile and hydrogen. The production cost of hexanedinitrile is directly related to the price of international crude oil. This year, the WTI future price of crude oil increased from 60.37 dollar/barrel of 3rd Jan. to 73.45 dollar/barrel of 28th Jun. Thus, the production cost of hexanedinitrile was also increased, and that will clearly affect the price of the hexanediamine. Secondly, the production halt of foreign magnates At present, the market of hexanediamine is highly concentrated and the foreign magnates dominate the production. But this year, the major magnates like Ascend, Invista and BASF have suffered the force majeure one after another in their production of hexanediamine. For example, the hexanediamine factory of BASF stopped its production due to an electrical accident. As a result, suspend production of great factories can lead to extremely tense market supply, and cause price increase of the hexane diamine. Thirdly, the sharp increase of downstream demand Hexanediamine is widely used, including the production of nylon 66 and nylon 610, manufacture of transparent nylon resin, synthetic polyimide carboxylate foam plastics, coatings, adhesives, rubber auxiliaries and the stabilizers and decolourant used in the textile and papermaking industry. Along with the increasing demand from the downstream industries, the supply and demand relation in hexanediamine market is tighter, and contributes to price increase of this product. source: CCIN been published after edit and translate
