According to QYResearch Construction and Chemical Research Center recently released China polycarboxylate water-reducing agent investigation report concluded that concrete admixtures developed very fast after 2000. Currently updated third generation: lignin - naphthalene - polycarboxylic acid. Polycarboxylate water-reducing agent is a kind of new water-soluble polymer material with comb-like structure composed of polyether monomer with different molecular weight and various kinds of unsaturated carboxylic acid, sulfonic acid and amide monomer, so that the concrete has Good fluidity and thixotropy make the complex concrete construction process becomes simple and easy. Polycarboxylate water-reducing agent free of formaldehyde, ammonia and other harmful substances, the production process of environmental protection, environmental pollution, on behalf of the most advanced technology of concrete admixture products, concrete admixtures in the replacement products.
At present, polycarboxylate superplasticizer is divided into polyester (MPEG) and polyether (APEG / TPEG) two categories, polyether type PCE water reducing agent appears later, but from the beginning of 2008 production, application began, By the end of 2010 the market of polyether type PCE water-reducing agent has more than 50%, the development is very rapid, mainly due to polyether superplasticizer processing is simple, stable performance, relatively low technical requirements, application promotion and other factors contributed.
In the superplasticizer industry boom, polycarboxylate water-reducing agent production stability, sustained and rapid rise. In 2005, the domestic polycarboxylate water-reducing agent annual output of only 50,000 tons, to its output in 2009 has reached 1.2683 million tons, an increase of more than 24 times. At present, many large-scale projects, such as the Qinghai-Tibet Railway, the Hangzhou Bay Bridge, the Beijing Olympic Stadium Museum Project, the Three Gorges Project, the Capital International Airport expansion project, the Soviet Union, the development of large-scale high-speed railway construction, Through the large-scale use of polycarboxylate water-reducing agent, polycarboxylate water-reducing agent is gradually replacing the traditional naphthalene-based water-reducing agent products, as a water reduction The mainstream of the market. At the same time, polycarboxylate water-reducing agent is also facing the bottleneck of technological innovation.
As a new generation of high-performance additives, polycarboxylate water-reducing agent in the application of the railway project is increasing, the current large-scale high-speed railway construction all require the use of polycarboxylate water reducing agent. Since October 2012, the Ministry of Railways has been on the water-reducing agent production enterprises to certification. According to China's concrete network statistics, as of May 10, 2016, a total of 134 water-reducing agent production enterprises through the railway water-reducing agent product certification and product certification. The list of the top ten enterprises, there have been nine companies through the Ministry of Railways certification. The promotion of railway projects for the production and application of polycarboxylic acid has accumulated rich experience, but also for the comprehensive development of the market laid the foundation.
At present, the industry concentration is very low, workshop a lot of business, and some do the synthesis, and some only complex. With the popularity of room temperature technology, industry access threshold is also getting lower and lower. Product homogeneity more and more serious. However, such enterprises are not the level of technical strength, quality control is different. In particular, the stability of the product at room temperature is often weak. But for some of the product requirements are not high, the price is very sensitive to the concrete business, but also barely enough. After 2015, trapped in the domestic economic downturn, the terminal market downturn, upstream production capacity and other unfavorable factors, polycarboxylate water-reducing agent business in the last year's general sales decline, half of the enterprise in 2015 polycarboxylate water-reducing agent Sales have declined. But in the case of the overall economic downturn last year, as a polycarboxylate superplastic agent rookie business, Jiangsu, China Railway Ao Leite against the wind, to achieve a steady growth in sales, among the top ten list. Domestic commodity concrete market is saturated, but the subway and highway, marine concrete is still in high-speed construction, while industry net profit is low (only about 10%), some small workshops business face with great pressure, the industry is also facing Re-shuffle the situation. However, foreign markets, especially other countries in Asia and Africa are high-speed construction period, there is a big potential for development, so the export of water-reducing agent business there are still many opportunities.
China National Bureau of Statistics released statistics data on April 17 "The national economy continues steady progress, good development trend,and increasing positive changes since the second half of last year, the main indicators are better than what expected before, this is a good start, and lay the solid foundation for the completion of the annual development target."
The gross domestic product (GDP) of the first quarter was 1,868.3 billion Chinese yuan, rise up 6.9% from comparable prices."
Sales data of mobile industrial vehicle industry from January-March shows that: total sales quantity is 118979 units, the year-on-year growth rate up to 34.85%.
This good situation is mainly due to the stabilization of the economy rebounded, significantly faster growth of manufacturing, transportation and other heavy forklift truck users .
The growth of forklift market is the direct embodiment for professional needs expand and deepen of the domestic material handling market. As a forklift material handling function personalized professional tools, forklift attachment with the same surge in demand, the domestic forklift attachment market has reached an unprecedented active period. This is a great opportunity for HEZE, and also a challenge.

How to Clean Outdoor Hiking Backpack, here are five steps to clean Step 1 If you notice a stain, food spill or plant matter (like tree sap or berry stain) on your backpack, wipe it off immediately with a damp cloth (and mild antibacterial soap or detergent if you have some with you). This will prevent staining and will also prevent buildup, which can draw ants and other bugs and cause the material to wear through. Step 2 When you're home, give the pack a thorough cleaning (but only when you know there'll be a few days between your hiking trips). Remove the detachable pockets and clean them separately from the main pack. Brush off or vacuum the pack outside and inside to remove dust, dirt, rocks, sticks and debris. Wipe down the outside and inside with a damp cloth, using mild soap or detergent that is chemical- and dye-free. The chemicals and dyes in traditional soaps can wear through the layers of waterproofing on your pack and increase the chances of rips and tears in the material. Step 3 To clean corners, use an old toothbrush to scrape out debris, and remember to check between the fabric and the frame for dirt and dust. For zippers, trim all excess threads and remove debris with an old toothbrush. (It doesn't hurt to use a small amount of silicone spray on the zippers each time you clean your pack to keep them lubricated and prevent rusting or sticking.) Step 4 Once you've cleaned both inside and out, rinse off all traces of soap. You can do this by submerging the pack briefly in a bathtub filled with cold water, but it's easier on the material and on you to hose it out with a detachable showerhead or a garden hose. Make sure all suds are out and that no soap has built up in corners or small pockets. Hang the pack upside down to dry in a cool, dark area. Hanging it up outside on the line is best, particularly if you can avoid direct sunlight; indoor drying will work if the area is well-ventilated. A circulating or ceiling fan will speed up the drying process, but at least 2 to 3 days of drying is recommended. If smell persists, use a backpack-safe spray that won't eat away the laminate on the material to freshen it up. Step 5 It is possible to wash a backpack in the washing machine, but it is certainly not recommended and should be used only as a last resort in cases of mildew, mold or old, smelly food stains. If you've tried all the steps above and still feel the pack needs to be washed more thoroughly, you can try the washing machine, but there's no guarantee it won't ruin your materials, clasps and attached elements, forcing you to buy a new pack anyway. If using the washer, never soak the pack in soapy water. This can cause holes and tearing in the material. Clean out all debris from corners and seams and remove the frame, all metal stays and detachable pockets. Wash on the delicate cycle in cold water only, and only use a mild or chemical-free detergent. Never tumble dry the pack--always place upside down to drip-dry in a well-ventilated, cool area.

What is ISO smart card? Smart Cards are defined in a standard called ISO 7816. This has different sections that cover physical size and characteristics, where the contacts should be (for contact cards) and how to communicate with them.
ISO 7816 does not define the electronics and a smart card can have just a memory chip, or more likely nowadays, a microcontroller and a memory chip. The standard does define how data should be read/written to the memory, using serial communications. This is often called “Phoenix” mode in discussions about smart cards. A second communication protocol uses a clock and is known as Smart Mouse.
The Smart Card Programmer we sell supports both these modes, so can be described as supporting ISO 7816 smart cards. These cards are used for telephone cards, bus passes, door entry and all sorts of applications, but for obvious reasons such cards are often encrypted and do not allow writes.
Simple smart cards that just contain memory are available, for example Infineon SLE5528 with 1024 bytes of memory and a 32 bit protection memory, to prevent unauthorised writes. The DLLs that come with the smart card programmer support these cards, and the developers SDK gives lots of examples in C++. Even simpler cards that just contain a 24C64 EEPROM can be supported by the DLL in the smart card programmer.
As well as these generic ISO 7816 smart cards, there are cards based on AVR and PIC microcontrollers, known as Gold card, Silver card, Yellow card, Fun card etc. The smart card programmer reads and writes the EEPROM chip on these cards by programming code into the PIC or AVR microcontroller that will read or write to the EEPROM chip on the card i.e. access to EEPROM memory is not direct but is done by the microcontroller.
On metal RFID tag is specially designed to be mounted directly on metal.
Mounting or embedding RFID tags on metal is a tricky proposition for the uninformed, and the informed for that matter. Metal surfaces reflect energy emitted from RFID readers and create interference for RFID tag antennas, which means the tag isn’t able to receive power and transmit information; however, specific RFID tags will work around metal surfaces. RFID companies have patented technology that allows RFID to work when attached to metal surfaces and even embedded within metal products. As long as you choose the correct RFID equipment for your situation and application, you won’t need to worry about interference from metal.
Here’s a few tips to help you get started: 1. What industries are using metal mount tags?
RFID on metal tags are perfect for asset and tool tracking in medical devices for healthcare, laptops & servers in IT (information technology), industrial manufacturing, oil & gas pipelines, vehicle tracking identification, and many other industry verticals. With the recent developments in RFID technology, the possible applications of metal mount RFID tags are expansive in scope. 2. What sort of conditions and environments are metal tags suitable for?
Because so many metal surfaces are exposed to harsh conditions, many RFID on-metal tags are specially designed and equipped to withstand harsh conditions. These rugged RFID tags are typically encased within a hard shell and will survive hard impacts, moisture exposure, and extreme temperatures. 3. How can I attach these Read on Metal tags to different metal surfaces?
Since the employment of metal mount RFID tags vary greatly across different industries, manufacturers provide tags suitable for the environments of your applications. Each style of on-metal tag has a unique method of attachment.
Printable & Flexible Tags Flexible RFID Tag. If you need printable RFID tags that work with metal, a few manufacturers offer tags that attach directly to metal surfaces with adhesive. Several of these tags feature a paper face, so you can print private logos, product information, or scannable barcodes directly on the label. If you need a paper label RFID tag that can still withstand harsh environments, MetalTag offers flexible RFID tags allowing them to adhere to curved surfaces. Also, Smartcardrfidtag.com offers a line of flexible tags allowing you to adapt your RFID system around your needs.

If you really think about it this way, generally, the originals of these types of paintings are almost all kept in museums all over the world, and now you can have one at your very own house to look at and enjoy anytime you want! Imagine having Starry Night by Vincent Van Gogh's replica artist in your home.
When making a purchase, you should select a site（www.topoilpainting.com）offering paintings from several artists. For instance, it is better to shop from a site offering Van Gogh paintings, Klimt paintings, Da Vinci painting, Renoir painting, Rembrant paintings, Monet paintings, and more. Shopping form this site will help you choose from the best of the best art works.
* Another important thing that will help you make a better purchase is your knowledge about different styles of oil paintings. Here, you should learn a little more about styles like impressionism, art nouveau, baroque, post-impressionism, and neoclassicism.
* If you don't know what types of paintings should be bought for your home, you should explore the range of still life paintings. These are the kind of paintings that compliment all sort of interior settings. So, you will never go wrong with them.
* Another great thing to do is to get family portraits done with oil paints. Hanging a full size family portrait in your home will surely impress all your visitors. So, consider this particular option to create an impression on your visitors.
When a person decides to buy oil painting, then they must check for unique styles and non-representational style of the artist. It is advisable to visit the venues where art paintings for sale are available. There are more Cheap Oil Paintings and Discount Oil Paintings.
The modern art painting express the abstract expressionists, the contemporary art has more controlled and organically inspired thoughts reflected in the paintings. The art paintings for sale will usually be a mix of oil paintings that are original and the cheap oil paintings as well as mixed media collages. These will be a combination of all the feelings experienced by the people at the same time. Some of the highlights of a recently visited oil paintings sale are described briefly:
1.The small paintings with a canvas dimension of 5 inches by 7 inches reflect the synchronistic approach of the artists. The variations observed are the collage elements, textures, colours and the spontaneity of the feelings felt by the artist. 2.The larger paintings of the dimension 47 inches by 60 inches look like a bit immature. The confidence with which the smaller art pieces are done is not available in the larger pieces. The very look gives the impression that the larger canvases are done by new artists who still fear the work to be placed next to renowned oil paintings artists. At some places, the combination of colours and visual balances were seen missing 3.The expression of memories and sensuous parts of life appeared more of repetition. The primary circles and pattern were inspired from the existing works and looked more of reproduction work except for the modern background. The creativity was lacking.
A casual walk through of the art gallery of oil paintings will give so much to learn from. The critiques will definitely be there. But while buying the art work oil paintings it is pretty important that one takes along a professional artist and choose the right kind of oil painting. It is imperative that cheap oil paintings will be available at throw away price but the work will have all the lacunae mentioned above. The confidence of the artist is more important in using the colours, paints and the canvas area. Otherwise, the art work though appropriate to naked eyes will over time become worthless. Otherwise, a professional can be hired to have the kind of unique art work done which will not be replica of any other art.
