Choose a reasonable repair method can effectively reduce project costs, shorten the construction period and reduce the negative impact on the environment , traffic . Various mechanic method has its own unique side, there are common basic points can learn from each other through . From that point, the classification of trenchless repair technology electrofusion coupling mould induction, to further understanding and promotion of trenchless repair technology will be beneficial.
A repair method of classification
1, according to the useful life can be divided into temporary and long-term repair ( permanent ) repair ;
2, according to construction methods can be divided into grouting , embedded reinforcing method , coating method, and lined pipe collars law method ;
3, according to the repair site can be divided into point-like repair and overall repair two major categories ;
4, according to the purpose of the repair can be divided into anti-leakage type , corrosion -and strengthen the structure type categories.
Second, the repair methods
By punctate repairs and repairs to the whole division, is a basic method sewer repair technology classification.
1 , point-like many pipeline repair damage only occurs at the interface part of the pipeline , if only to repair the interface , which is called point-like repair (SpotRepair). Point into the interface embedded complement repair , grouting , collar law , local cured resin . Many damaged pipelines lives less than a decade , tube structure intact, but the interface leakage . For this type of pipeline repair using point is reasonable . Early point-like repair method is relatively simple, relying on staff access to repair leaks in the pipe directly , it can only be used over 800mm diameter pipes . ( 1 ) Interface embedded complement
Interface is the application of the first embedded complement trenchless pipe repair technology , first fill material embedded in cement mortar , chiseled after the old joints, finishing with quick dry cement or asbestos cement expansion manually embedded complement . In recent years, chemical materials increased, tar epoxy mortar , polysulfide sealants , polyurethane vinegar began to replace cement mortar. Chemical mould maker seal material has good flexibility , good resistance to deformation than the cement mortar.
Interface embedded complement although cheap , there is no impact on the flow cross-section , but poor quality stability . If staking cleaning is not clean, not dense embedded complement , these human factors can affect the reliability of the repair . In addition , the interface embedded complement duration is relatively long ( 2 ) grouting
Through the tube and interface parts soil grouting , plugging groundwater seepage into the pipeline route is yet another point-like repair methods . According to different grouting materials can be divided into two types of cement grouting and chemical grouting ; according to setting mode grouting pipe can be divided into the tube ( outside ) drilling grouting and ground ( down ) two drilling grouting . Grouting from the ground down there is a big blind should not place more than note the note , the note of the ground ( such as the bottom part of the tube ) is difficult to inject enough .
In recent years, small pipe tube grouting technology has also made great progress. The airbag will be closed on both sides of the interface , and then injected into the joints of chemical pulp , chemical pulp curing water swelling soon after plugging leaks . And other engineering methods compared to the relatively poor reliability grouting . Therefore, its use in the United States and Japan are subject to certain restrictions , such as the requirement to conduct post- grouting visit every six months , or leakage should not use more than a certain amount and so on. Grouting is often used as an adjunct or temporary plugging method of application , generally can not use the law as an independent work . Grouting is usually embedded reinforcing method and interface combined effects of ( 3 ) sets of the Tour de France
Mounting interface sealing collar portion is a common point repair methods . The vast majority of the Tour de France sets quality stability than the embedded reinforcing method is good, and fast construction speed , but the collar method has some influence on the flow. Collar method can be divided into the following categories:
① Antao ring scaffolds can be divided into : ordinary steel rings, stainless steel rings , PVC sleeve ring.
② Press the seal can be divided into : rubber water seals ( ribbon ) , rubber sealing rings ("O" type ) seals , PE water stop seal ( ribbon ) , polyurethane grouting . ③ by way of installation : can be divided into manual installation ( diameter 800mm and above) and airbags plastic injection mould installed ( diameter 800mm or less ) .
Rings have been used :
① ordinary steel rings : steel rings into the 2-3 valve assembly in the tube , collar lined with rubber water in between the main pipe . Pipeline wrong port or interface injustice often affect the sealing effect , ordinary steel rings easily rust.
4 ) partial curing resin
The partial gelling is actually a method for repairing the whole point repair practice , there are two kinds :
① artificial fiberglass Interface : personnel into the tube , embedded interfaces do first up , and then in the interface area to do fiberglass liner.
② local forming felt tube airbags : filling resin coated tube with a balloon felt so close to the main pipe , and then heat cured with ultraviolet light and other methods . Felt barrel shaped balloon partially whole scene is actually a method of curing localized approach.
2, the overall repair
If a pipe repair from start to finish , this is called the overall repair (wholerpair). Overall repair is the entire pipe between two manholes reinforcement repair , this repair can be divided into two categories : one is the coating, and the other is the liner method. Coating method is suitable for the diameter of 800mm or more, anti-corrosion, anti-seepage pipes for the purpose of repair .
Liner can not only repair the pipeline corrosion, seepage and can increase the structural strength of the pipe . Liner construction method is fast , reliable , and therefore has become the mainstream of trenchless sewer repair . But the cost is correspondingly higher loss of some liner construction method is relatively large cross-section of the pipeline .
( 1 ) coating method (coating)
Coating method to enhance the role of the structural strength does not only play a role in anti-corrosion and anti-seepage . Little impact on the pipeline coating method section , the relatively low prices, but long duration, reliability, poor quality , pipeline construction cleaning process , temperature, ventilation , personnel quality will affect the repair quality.

China's mold industry will be the high road by car dies
China's mold is the only way for enterprises to develop high-end line of automotive die.
According to statistics, last year China's key enterprises reached nearly 110 die, which accounts for about 37% of stamping dies, these data demonstrated a strong automotive mold manufacturing country, China has become a fact. However, the development of China's automotive die but not so ideal, high-end automotive mold enterprise technology is not up to the level of technological innovation capability, inadequate new mold R & D capabilities, etc. The reason for this series are restricting the development tapping tee electrofusion mould of China's automobile mold industry leading automobile companies can not produce molds and dies to match the high-end market, high-end car manufacturers need to mold must also rely on imports. The domestic high-end enterprise occasionally die because of lack of production load, had to change the initial market positioning away seize, the low-end market. Although the survival of the enterprise to solve the problem, but because of the low-end market, low profit margins, leading to invest R & D and technological innovation rarely, under certain circumstances, a vicious cycle in which companies did not enter a virtuous cycle of development , the domestic mold companies are more high-end cars, making it faces increasingly fierce competition in the market. In addition to the domestic high-end automotive mold companies to meet the traditional mold enterprise Q (quality), C (cost), T (period) requirements, mold development and electrofusion coupling mould application of new technologies will become the focus of the future direction of domestic mold industry development. Multi-position progressive die and precision die represents the development direction of stamping dies, precision and demanding life, mainly for the electronic information industry, automotive, instrumentation, electrical appliances and other facilities. Both mold, the country has fairly basic, and has the introduction of foreign technology and equipment, the products of individual enterprises has reached the world level, but most companies are still a large gap, the total is also in short supply, import more.
For ultra large scale integrated circuit Bridge Bend mould package for more than 100 and a lead foot gap 0.2mm below the lead frame package for the accuracy of 5mm or more matching precision miniature connector for 1.6mm below the core support and micro-motors for the CRT electron gun and supporting the development of precision molds is a top priority.

China Mould market is expected to develop a large flow of commerce shall be bullish pattern
A wide assortment of hardware products, China has gradually become the world's largest metal processing and exporting countries, and has become one of the world's largest producer of metal, has a vast potential market and the consumer. International Mould & Metal & Plastic Industry Suppliers Association mold market is an important part of China's hardware chinese mould industry, the five-time major changes are properly deal with our domestic and international environment for development, accelerate critical period to achieve the target of building a moderately prosperous society, but also China mold manufacturing the healthy development of the critical period, although many uncertainties in domestic and international environment, but China's economic development is still in the period of rapid growth, China's comparative advantage in the international mold mold market still exists, the domestic market is also expected to continue to be optimistic mold, mold industry development shows the trend. As more and more multinational companies entering the plastic coupler fittings mould country, our local hardware business advantage is being challenged. Luo Baihui that our hardware is stainless steel enterprises, especially growth companies must clearly, must seize the strategic opportunities for development, the establishment of reasonable development goals for themselves. Not upstream, there is only the road to extinction. In the end business is to maximize profits or to create value for customers or for the benefit of employees? These points are business goals, but it simply speaking, if we are there to choose only one of the most important target, the value is the highest pursuit of business objectives.
Precision molds will be higher. 10 years ago, precision, precision molds is generally 5 microns, has now reached 2 to 3 micron, 1 micron precision die soon will be listed. This requires super finishing. Mold industry will become increasingly large. This is due to the molding of parts increasingly large-scale and high production efficiency requirements and the development of a multi-cavity mold caused. Multifunctional composite mold mold industry will be further developed. In addition to the new multi-functional composite mold stamping parts, but also responsible for layers, tapping, riveting and assembly tasks such as locking, the performance requirements of steel are also increasing. The Chinese hardware companies how to move forward mold in the rain it? Improve the process of the socialist market economic system, that is, the process of rapid flow, the flow does not know, do not know how the socialist market economy, is to improve the economic operation of modern circulation speed, quality and an important factor in efficiency. Therefore, in order to ensure the continued prosperity of hardware manufacturing, accelerate the development of mold hardware industry, we must do the work of several aspects.
Modern service industry must improve metal mold industry, the development of big business, the formation of large circulation, open circulation pattern, establish an efficient distribution platform, completely change the current hardware distribution platform small, scattered, weak status; must improve industrial development every aspect of the process through the province hardware industry cluster, forming large clusters metal industry, extend the industrial chain, to form interlocking, complementary production patterns, and enhance the overall competitiveness of the hardware industry; must promote hardware production technological innovation and brand building enterprises; must accelerate trade integration and integration of domestic and international trade and industry, and promote the transformation of economic structure adjustment and economic growth mode; must be to develop new markets, expand consumption as the main line, make full use of e-commerce and network service platform to promote hardware large market system, modern logistics system hardware, hardware market monitoring system and hardware business credit system construction, metal industry modernization of circulation as soon as PE Electrofusion Pipe Fitting possible; need to improve communication and cooperation within the industry, sharing resources, the province's hardware business should be clearly aware of a variety of complex issues arise in the development process, we must pool everyone's wisdom and strength, the use of collective resources, while avoiding disadvantages, strengthen cooperation and promote multi-directional communication outside the industry, and jointly promote prosperity, the formation of the overall effect of the industry, actively respond to trade barriers may arise internationally active challenges to deal with the international market. Die hardware business leaders in determining the direction of development of the enterprise, to seize the key leadership, a clear focus on the work of enterprises, do not waste energy on other insignificant little things, if one thing can not promote staff enthusiasm, but also does not produce profits for corporate development role in promoting short-term or long-term, then it is unnecessary and can be ignored.

Situation Analysis of Chinese mold large industrial standardization system
Where the more developed industrial countries , more emphasis on standardization work , because to give industry brings quality, efficiency and effectiveness. Mold is a special forming tool products, although strong individual , but also industrial products , so standardization is very important. Die Die standardization work includes the development Plastic Ball Valve mould and implementation of technical standards , production and application of the standard mold and the relevant standards advocacy, implementation and promotion. China mold standardization work started late , combined with publicity and promotion efforts to implement small, so the mold behind the standardization of production , but also behind many industrialized countries in the world . Foreign mold developed countries, such as Japan , USA, Germany, mold standardization nearly 100 years of history, production and supply of standard-setting mold , mold standard parts , has formed a complete system . Guarantee of the Chinese die from work just after the establishment of the National Standardization Technical Committee of the mold began in 1983 . At present, China has about 20,000 units of production molds , mold production has made significant progress , but compared with the industrial production requirements , yet could not get one of the important reasons is that the mold and the level is not high degree of standardization .
China mold standardization system , including standard four categories , namely: basic standard mold , mold process quality standards , mold and die parts production-related standards and technical standards . Mold standard and can be mainly categorized stamping die mold standards, standard plastic injection mold , die casting mold standards, forging mold standard , standard fasteners cold heading die , drawing die standard , cold extrusion dies standards, standard rubber molds , glass molds and automotive die standards ten categories . Currently, China has more than 50 standard mold of electrofusion coupling mould over 300 standard No. 14 kinds of common devices and automotive parts and components die and 244 varieties of 363 standards. These standards development and advocacy to implement and improve the standardization of Chinese mold and level. With the increase in international exchanges , the development of the localization of imported mold -funded enterprises as well as its supporting mold made international standardization requirements , on the one hand in terms of attention to a possible standard-setting international standards or advanced foreign adoption of national standards , including the adoption of advanced corporate standards ; hand many standard mold manufacturing enterprises according to market needs , in addition to standard production outside China mold standard parts , as well as advanced enterprise standard production standard mold . Rich Teba such as Japan , Germany and other companies Haas test standards have been widely popular in China .
Die mold industry standardization concept often referred to more complex, different from the usual level of mechanical industry standardization . The latter generally can be measured by using the standard rate, while the former often refers to the use of standard mold coverage . As the Chinese would not die standardization work late , mold standard parts production, marketing, promotion and application of the work is relatively backward , so the standard mold fewer varieties of specifications, supply is not timely, complete and poor long-standing problem , so that the standard mold use the coverage has been low . Although this year due to foreign intervention , the ratio has been greatly improved , but overall still very low. According to preliminary estimates , at present it was fairly easy to between 40% -45 %. The international community generally above 70 %, of which more than 80% of small molds . Due to the different nature and areas where the Chinese mold companies , there is a big difference in the use of standard mold coverage . Funded enterprises than any other enterprise high , the South than in the North High enterprises . This is most obvious in Guangdong . Guangdong, a pipe elbows and bends mould large concentration of foreign-funded enterprises , they led to the transformation and development of other business concepts of the market, thus Guangdong mold companies use standard mold coverage is much higher than in other regions of the mold companies . Implementing the standard mold , using the standard mold , the mold can not only improve the quality and reduce production costs and shorten mold mold production cycle. Relevant statistics show that: the standard mold tooling companies can save 25% -45 % of working hours , mold production cycle can be shortened by 30% -40 %. As industrial product variety, low-volume, personalized, fast development of the production cycle , in order to improve the market economy rapid response capabilities and competitiveness in the mold production cycle are increasingly important in today's standardized meaning more die significant .
