EPS foam machine recycling:a good way for environment sustainable development

Environmentally sound Recycling, also called recycling technology is of the most important measures. At present, many research institutes in home and abroad EPS machine recycling research have reached practical way of EPS recycling method.

Mechanical recycling

This method can be divided into two kinds of simple regeneration and composite regeneration. Simple regeneration is mainly used for the production plant scrap, including easy cleaning a disposable waste recovered. its composition is relatively simple, clean. Recycled materials can be used alone or blended in a certain proportion. The new compound can be used with existing processes and equipment; it is mainly adopted and effective method.

1.EPS is made of recovered production XPS EPS wastes which is pulverizing pelletized. And then heated and melted adding a foaming agent, a flame retardant, nucleating agents and additives, obtained by the processing system of the XPS, are widely used for building materials. This recycling technology in the country has been promoted to a large area, and become one of the main ways of EPS machine recycling.

2. Recycling: Foam manufacturers through the crusher work, scrap and substandard products are made of particles of a certain size. This material mixed again with fresh pre-expanded beads can be forming sheet metal by forming machine or packaging machine which also can be made of various sizes and shapes EPS products.

3. The hot melt regeneration, use the foam particles machine

Second, after making light insulation materials discarded foam smash through infrared radiation heating, the volume is reduced to less than 1/20; then mixed with special cement made ​​of building materials, has been identified as non-flammable building materials. The construction material silencer effect is an average of 60%, for certain frequency noise suppression can be achieved more than 90%. This material is now being used as soundproofing walls and ceilings. In addition, EPS machine can also broken material to make lightweight block, interior and exterior insulation mortar and light mortar.

Other recovered the use of technology: Manufacturing rust belt rust paint; Manufacturing multi-functional resin; manufacturing seepage trapping agent; usage of asphalt enhancer.

Caterpillar Boost remanufacturing industry

A few years ago, Caterpillar has been expanding continuously. Caterpillar announced an excavator production capacity expansion plan will expand to four times in Xuzhou Factory till to 2014. The first half of this year, Caterpillar still committed to advancing the base of Jiangsu, Shandong and other expansion plans and plan launched caterpillar excavator.

However, according to the reporter from Caterpillar (China) insiders, trapped in the Chinese market downturn, the project has not been pushed substantially. Unlike traditional capacity stopped expansion in China, Caterpillar remanufacturing field increased development efforts.

Reporters learned that Caterpillar has become one of the world's leading manufacturing companies, annually recycled about 2 million parts in the global. Because remanufacturing can save 70% of the parts, as well as 80% of water, electricity and other energy resources consumption can reduce more than 60% of the cost, and thus obtained the attention by Caterpillar. 68 Caterpillar factories in 17 countries currently engaged in remanufacturing.

Caterpillar in China has established two manufacturing companies - Caterpillar Remanufacturing Industry (Shanghai) Co., Ltd and Yuchai Remanufacturing Industry (Suzhou) Co., Ltd. The former produce pump, motor and engine parts. Offer Service for parts remanufacturing business of the region, it while also providing services to external customers and other Chinese Carter business units. Latter was run by Guangxi Yuchai and Caterpillar joint venture enterprise.

 In fact, several years ago, Richmond had said that the next decade global remanufacturing market will reach 100 billion U.S. dollars. China may become the largest market in the field. Richmond told the reporter, remanufacturing is one of the fastest-growing businesses in Caterpillar. Remanufactured products have reduced costs for customers, and benefit for the environment, increasing in more business opportunities. Caterpillar in China further promotes the remanufacturing business development.

It is reported Caterpillar remanufacturing business has been extended from the eastern region to the western region of China, in July this year, Caterpillar Remanufacturing begin to layout southwest.

Richmond said, remanufacturing policy plays a key role in China. Before in 2005, re-manufacturing is a restricted industry, and later it comes to realize the great significance for the achievement of sustainable economic development, which has now become encouraged industry. But it is still not perfect in terms of standards, distribution, tax policy, may take a long time to solve these problems.

5 Major PRICTICAL UNBURNED BRICK MAKING MACHINE

Unburned brick making machine is in accordance with the purpose or characteristic is divided into hollow brick, cement brick, paving brick, concrete block brick, slope protection brick, river brick, square brick, as well as for special bridge brick.

Different brick machine production, the machine also become a different name, such as concrete pads, pad machine, pavement brick, hollow brick, small brick extruder. Different machines for different purposes, the name is different, the addition to the subtle differences their name called brick making machine.

Concrete pad machine: the production of concrete pad of the machine, its output pad has high strength, regular shape, easy to use, etc., low the pad the strength of traditional homemade cement mortar pads and plastic mold, anti-poor permeability and the bad concrete structure and other shortcomings, so the concrete pad machine popular market.

    Block machine: also known as concrete block machine, block machines are produced by brick making machine and block mold, so it was called unburned block machine. Block machine is mainly used for the block. Block can be divided into a solid block and hollow block as appearance shape. The hollow block three forms are single row of square holes, and a single row of round holes and multi-row flat hole. Multi-row flat hole is more favorable to the insulation which can be divided into the main block and various auxiliary block by block position and role in the group puzzle. Also called block mostly hollow, hollow bricks, also called hollow brick machine.

    Extruder: extruder is, brick-making machine, but the word "squeeze" visually depicted the processing of brick making equipment. Of course, such a device also produce bricks unburned, in fact, that is brick making machine.

    Automatic brick machine: brick machine with high degree of automation, automation is mainly reflected in: automatic batching (batching machine required), automatic feeding the brick host automation (plc control), and automatic stacking. Device model two generally used to indicate the degree of automation, such as 8-15 automatic, and 8-20, it is partially automatic.

    Hydraulic brick machine brick machine: hydraulic rather than mechanical pressing.

    Hollow brick machine: mainly used for the production of hollow brick machine, that is composed of brick the unfired brick making machine and hollow brick molds

Sany re-manufacturing concrete pump truck successfully exported to Arab

Recently in Changsha, Hunan Province, after qualified Sany production units, the value of $ 1,124,000 remanufacturing concrete truck successfully exported to the United Arab Emirates. This is the first batch of remanufacturing machine export from Hunan Province. With obvious Cost-effective advantage, construction machinery remanufacturing products become a new way to Changsha construction machinery enterprises to expand exports.

Affected by the global economic situation, Hunan construction machinery exports dropped. According to enterprise analysis, the main models of engineering machinery ownership amounted is 2.9 million units, lot of them are idle. Huge market capacity means that many products will be eliminated as scrap iron and steel after a certain number of years, resulting in a huge waste. In addition, in Southeast Asia and the Middle East, economy is relatively active. They are devoted to boost their economy, increase investment in infrastructure construction. There are an urgent need for a large number of high qualities and low price of construction machinery products. Therefore, the development of engineering machinery manufacturing export is right time. 

It is understood that, the remanufactured by no means a simple renovation of the second-hand products, but on the implementation of the transformation of low-carbon green industries of high-tech repair the product life cycle of old products. Remanufacturing has basically the same as new performance and reliability, is a kinds of advanced form of recycling.

It is understood that the countries have strict mandatory technical standards and requirements of the useful life for remanufacturing engineering machinery, such as Vietnam to import construction machinery remanufacturing which original useful life not more than three years. To ensure the remanufactured product quality and performance, the council established a full seamless regulatory mechanism. 

1. Specific measures to control remanufacturing qualify and other requirements

2. Random inspection to ensure compliance with the manufacturing requirements of enterprises in the domestic recycling old machinery for export remanufacturing

3. Cleaning, dismantling, repair, heavy equipment and other sectors take the new tracking survey.

4. In accordance with the requirements of new technical standards, on the export of manufactured mechanical implementation of the by-station detection, debugging, and strict implementation of identity inspection.

5. At the same time, enterprises establish product files and track information systems.

SANY and Zoomlion these two major concrete pump truck machinery giant has signed with foreign customers remanufacturing sales contract nearly the value of millions of dollars.
