HC plastic mesh News: "Although our development of the industry presses have been able to meet the needs of the domestic market, but compared with developed countries and regions, there are six gaps, can not be ignored." China Plastic Machinery Industry Association, before the Secretary-General Su Tung Ping, said in an interview.

Development philosophy and mode gap Su Tung Ping said: "China's plastics machinery industry was first started from the imitation, and then determined according to the demand of plastic market, what type of production. This is more applicable to passive decision-making industries small, high-quality talent shortage, the shortage of Economy Period. After several years of development, now China's plastics machinery industry has begun to take shape, with a certain amount of strength and further development. At the same time every industry in the use of plastic machinery, the original plant-based plastics to plastics processing industry is no longer representative of the buyer's market of plastic machinery, therefore, can not go copying the previous model, while the need for buyer's market characterized by under the premise of thinking. "

According to Su Tung Ping introduced, according to the international popularity of the model, advanced antenna manufacturers of plastic machinery, already deep into the direct consumer market. They continue to research, find and discover the needs of the consumer market (including civilian and industrial consumption), self-developed new Plastic Products , Then this machine is designed, arranged process recipe, for the equipment up to a set of users, including processing equipment included, can be successfully made into a new turnkey product.

This way is completely different from the traditional "what users need, what to produce" passive mode, but a positive initiative to guide the market consumption patterns. To reach this point requires a lot of innovative high-quality management personnel; require significant interdisciplinary, cross-industry high-quality personnel; need for effective, broad, cross-flow system of social information.

Gap between design concept Present, foreign plastic machinery design is by popular demand to the principle of processing products allow users to win in the market for the idea, as the equipment design and manufacture of special equipment to users. The resulting emergence of many new technologies, such as three-dimensional circuit technology, double bubble tube film method, metal plastic processing technology, combined with mixing and injection technology, with the double Screw Direct extrusion technique, melt pumps and hot runner technology, gas-assisted and water assisted injection technology, and thus leads to the so-called "modular" design approach.

Su Tung Ping pointed out, most of China's plastics machinery business, still follow the traditional standard model plus improved routine, trying to adapt to the ever-changing market demand, lack of flexibility and competitiveness in the market.

Efficiency, saving energy gap

High-speed, high efficiency, energy saving in recent years has been the theme of international plastics machinery industry. In this regard, the majority of our existing energy consumption of plastic machinery, mostly abroad, 2 times the same type of aircraft, speed is generally about half the foreign equipment; product development cycle is about 3 times abroad, the product is half life than abroad . Su Tung Ping to energy efficient Injection molding machine For example, that foreign-made machine energy consumption is high all electric injection molding machine 2 to 4 times. Extrusion technology with high efficiency, high speed and efficiency of the plasticizer system development and energy saving, high efficiency, fast response, dual-axis servo control system, have to be further improved.

What a New Car Actually Costs

By Rocco Morroco

Car Price

At a time when car possession will not be an option in most US places, the monetary strain felt on our middle class as a result is staggering. Do you know that sixty four% of American debt is non-revolving loans, reminiscent of student and auto loans? The identical statistics say that the common car loan is $30,four hundred or more. With these buyers investing solely a 9% down fee, they are financing the other $27,664. With the average American wage being just shy of $30,000 a year, you can see what a critical investment new car possession is on Americans.

Financing cost

In 2009 The Fed reviews the common APR on auto loans was 3.eighty two% with a finance time period of simply over 60 months. The total monthly cost works out to be $507.23 per thirty days at those rates. In 60 months you’ll have paid again $30,433.eight totaling $2,736 paid in interest.

Insurance coverage

In the second quarter of 2010 the typical auto insurance rate was 1,812. Which works out to be $151 per month. Again, quite an expense when having car insurance is required by law. Mixed with the auto mortgage fee the total is as much as 658.23 per month.

Gas

In 2009 the common American spent $2,208 on fuel, or $184 per month. Added with the previous prices, we’re at a total of $842.23 per month.

Whole Cost

Just combining the expenses we now have talked about, setting apart common maintenance and sudden maintenance, the entire yearly expense for a brand new car, based mostly on the national averages would be $10,106.76 per year. Multiply that by 5 years (60 months) and the full quantity that you simply paid to own a new car was $50,533.80.

How staggering is it that on average we spend 1/three of our annual salary simply to drive a new car?

Cetane number

By w3hbre

Definition

Cetane number is actually a measure of a fuel’s ignition delay; the time period between the start of injection and start of combustion (ignition) of the fuel. In a particular diesel engine, higher cetane fuels will have shorter ignition delay periods than lower cetane fuels. Cetane numbers are only used for the relatively light distillate diesel oils. For heavy (residual) fuel oil two other scales are used CCAI and CII.

Typical Values

Generally, diesel engines run well with a CN from 40 to 55. Fuels with higher cetane number which have shorter ignition delays provide more time for the fuel combustion process to be completed. Hence, higher speed diesels operate more effectively with higher cetane number fuels. There is no performance or emission advantage when the CN is raised past approximately 55; after this point, the fuel’s performance hits a plateau.

In Europe, diesel cetane numbers were set at a minimum of 38 in 1994 and 40 in 2000. The current standard for diesel sold in European Union, Iceland, Norway and Switzerland is set in EN 590, with a minimum cetane index of 46 and a minimum cetane number of 51. Premium diesel fuel can have a cetane number as high as 60.

In North America, most states adopt ASTM D975 as their diesel fuel standard and the minimum cetane number is set at 40, with typical values in the 42-45 range. Premium diesels may or may not have higher cetane, depending on the supplier. Premium diesel often use additives to improve CN and lubricity, detergents to clean the fuel injectors and minimize carbon deposits, water dispersants, and other additives depending on geographical and seasonal needs.

Dimethyl ether may prove advantageous as a future diesel fuel as it has a high cetane rating (55) and can be produced as a biofuel.

Alkyl nitrates (principally 2-ethyl hexyl nitrate ) and di-tert-butyl peroxide are used as additives to raise the cetane number.

Biodiesel from vegetable oil sources have been recorded as having a cetane number range of 46 to 52, and animal-fat based biodiesels cetane numbers range from 56 to 60.

Chemical relevance

Cetane is an un-branched open chain alkane molecule that ignites very easily under compression, so it was assigned a cetane number of 100, while alpha-methyl napthalene was assigned a cetane number of 15 . All other hydrocarbons in diesel fuel are indexed to cetane as to how well they ignite under compression. The cetane number therefore measures how quickly the fuel starts to burn (auto-ignites) under diesel engine conditions. Since there are hundreds of components in diesel fuel, with each having a different cetane quality, the overall cetane number of the diesel is the average cetane quality of all the components. There is very little actual cetane in diesel fuel.

Measuring cetane number

To measure the cetane number properly is rather difficult, as it requires burning the fuel in a special, hard-to-find, diesel engine called a Cooperative Fuel Research (CFR) engine, under standard test conditions. The operator of the CFR engine uses a hand-wheel to increase the pressure within the cylinder of the engine until the time between fuel injection and ignition is 2.407ms. The resulting cetane number is then calculated by determining which mixture of cetane (hexadecane) and isocetane (2,2,4,4,6,8,8-heptamethylnonane) will result in the same ignition delay.

Ignition quality tester

Another reliable and more precise method of measuring the cetane number of diesel fuel is the Ignition Quality Tester (IQTTM). This instrument applies a simpler, more robust approach to CN measurement than the CFR. Fuel is injected into a constant volume combustion chamber in which the ambient temperature is approximately 575C. The fuel combusts, and the high rate of pressure change within the chamber defines the start of combustion. The ignition delay of the fuel can then be calculated as the time difference between the start of fuel injection and the start of combustion. The fuel’s derived cetane number can then be calculated using an empirical inverse relationship to ignition delay.

Cetane index

Another method that fuel-users control quality is by using the Cetane index (CI), which is a calculated number based on the density and distillation range of the fuel. There are various versions of this, depending on whether you use metric or Imperial units, and how many distillation points are used. These days most oil companies use the ‘4-point method’, ASTM D4737, based on density, 10% 50% and 90% recovery temperatures. The ‘2-point method’ is defined in ASTM D976, and uses just density and the 50% recovery temperature. This 2-point method tends to over-estimate cetane index and is not recommended. Cetane index calculations can not account for cetane improver additives and therefore do not measure total cetane number for additized diesel fuels. Diesel engine operation is primarily related to the actual cetane number and the cetane index is simply an estimation of the base (unadditized) cetane number.

Industry standards

The industry standards for measuring cetane number are ASTM D-613 (ISO 5165) for the CFR engine and D-6890 for the IQT.
