Cement Products Machinery Industry Situation and Development Prospects
Situation 1 Cement Products Machinery Industry
Cement products machinery industry by the cement products machinery machine and spare parts nationwide block, precast, panels and prefabricated shaped components manufacturing enterprises and research design, equipment users and other relevant units. Cement products machinery mainly the production of concrete products, with its cement-based cementitious materials to sand, stone aggregate, industrial waste or fly ash as admixture with admixtures of materials production of various shapes and sizes the products include: building blocks, with pavement blocks (bricks), hydraulic slope block, concrete pipe, concrete pipe piles, precast concrete beams, concrete prefabricated housing member and a new precast floor panels, etc. .
Cement products machinery in accordance with the production of concrete products into functional block machinery, wall molding machinery, concrete pipe molding machinery, concrete structures forming machinery Pipe forming machinery, tile machinery. Mechanical block is divided into block making machine, mixing ingredients production line, block scission machine, kiln cars, palletizers, pallet and product transport equipment, mold, block cutting hair machine, block machine striped nap, block finishes processing machinery. Wall molding machine into light wall molding machine, molding machine gypsum wallboard, cement and fly ash composite sandwich panels production line, composite exterior insulation board production lines. Cement pipe molding machinery is divided into vertical pipe extrusion machines, hanging roller cement pipe machine, centrifugal tube machines. Mechanical molding technology products mainly vibration molding, extrusion molding and centrifugal molding three basic ways, block molding machine mainly uses two vibration vibration and Taiwan vibration molding process, concrete pipe extrusion molding machinery have two kinds of molding and centrifugal molding process.
Under the impetus of wall materials innovation policy, concrete block industry for nearly 30 years of rapid development in China has formed a large industrial scale, the huge market demand of different specifications to make block machinery, etc. overall performance improved rapidly. Block production equipment internationally famous enterprises enter the Chinese market, such as the US Bessel, Colombia, Germany Martha Hayes, Japan Tiger and so on, our block machinery has played a great role in promoting. Currently, according to industry to incomplete statistics, various block equipment manufacturing enterprises reached more than 200, wallboard production equipment more than 10 enterprises, more than 20 floors equipment manufacturers, tile equipment manufacturing enterprises more than 10, cement pipe production equipment more than 20 enterprises, machinery and equipment products manufacturing enterprises more than 100, a conservative estimate of mechanical products and accessories business in the industry will be more than 400. Annual production value of the industry is expected to 100 ~ 12 billion, but the industry average scale of enterprises is generally low in the scale of operation over a hundred million enterprises are not more than 20. 2009, domestic market sales of concrete block production equipment single shift production capacity of over 25,000 m3, about molding equipment 300 (sets), in which the fully automated production line with a lifting plate and machine Zimu vehicles accounted for about 25%, with a pack machine, simple semi-automatic production line forklift handling about 60%. 2009 No import declaration molding machines, molding machines and ancillary equipment exports actually delivered amounted to approximately $ 16.5 million. 2009 National Sales concrete block (brick) equipment (including equipment) of approximately 10 billion yuan, about 1.2 billion yuan mold, the pallet of about 1.5 billion yuan.
Block molding machinery is a variety of factors aggregate size, water-cement ratio, workability, and the initial pressure, vibration frequency, amplitude, vibration methods are interrelated complex process. Under certain external pressure, amplitude, frequency and direction of vibration are three main parameters of vibration molding, which not only aggregate particle size, quality, severity, but also to die inside the material distribution. With today's computer-controlled technology, mechanical block weighing measurement technology, mixing technology, transportation technology, fabric technology has improved greatly, but our block molding machinery vibration amplitude, frequency, phase 3 the main parameter control, the whole job stability and adaptability of different materials and foreign technology, there are some gaps compared.
Vibration is a major producer of concrete products molding process, through the point of contact with the concrete mix cement pipe mold, the vibrational energy introduced into the concrete mix evenly and uniformly transfer, vibration parameters depend on the concrete mixture was adjusted to accommodate different mix of . The main parameters affecting the quality of post-release concrete products are molded body strength, the general strength of the green body stripping 0.4 ~ 0.5MPa. Dry concrete water-cement ratio is usually 0.35 to 0.45, the amount of cement is generally 270 ~ 350kg / m3. In addition to the amount of cement and water, the green strength also depends on the type of aggregate and particle size distribution, surface condition aggregate, cement type, water demand and solid material bulk density, content of powdered materials, Admixtures and additives blended volume, density and compacting process kinetic energy is introduced during the molding at ambient temperature.
At present compacting process mainly uses shock vibration compaction method, harmonic vibration and shock at the same time introducing a concrete mixture. Molding equipment according to the mechanical parameters and properties of fresh concrete, set the vibration waveform and shock vibration frequency, so that the die produces dense compaction force compression mixture. Discovering Harmony in shock two vibration modes, shock vibration noise, high load equipment, pallets and mold wear faster when producing the product is changed, parameter adjustment workload, the interaction between all the parameters, the device wear They tend to make mechanical settings can not be in the best state, resulting in product quality. Resonant wave vibration at high frequencies, high amplitude vibration system equipment conditions all work body (multi-DOF) can produce oscillation, when the product is changed only a small number of parameters can be adjusted, high product quality stability . Wave resonant vibration due to elimination of shock, mold equipment wear and greatly reduce the spread of noise, vibration force significantly improved, can be increased from 200KN to 800KN.
From the development of the industry as a whole situation, as China's rapid development of urbanization and energy, and promote the building of low-carbon environmental policy in recent years, concrete products industry is developing rapidly, led to the rapid development of mechanical products, mechanical products, market demand continues to expand, result in equipment and related parts manufacturers continue to increase, the gap between products and machinery industry, the overall level of international advanced level of shrinking.
The overall level of the team from the industry point of view, the number of business practitioners, small scale, the uneven quality of employees, lack of design and development staff, full lower average labor productivity.
From the product performance and quality point of view, although in recent years by learning foreign advanced technology, equipment technology has been greatly improved, and some enterprise products into the international market, with international counterparts to compete on the same stage, but high-quality products in the industry of high-performance products lower total proportion of products on the market overall performance quality and production stability, compared with the international advanced level quite different.
From the industry point of view of existing standards, cement products machinery industry, product variety, small quantity standard, the standard system is not complete, we can not cover the requirements of the current technological development of the industry, a variety of equipment no industry standard to follow, and some existing industry standard mark age longer, with the current products on the market can not meet the requirements, it is not conducive to technological progress and improve the quality of the product.
2 cement products machinery industry problems
2.1 cement products machinery work low stability
The industry backbone enterprise product quality, technical performance and stability of the quality can be comparable with international counterparts, but some cement products machinery manufacturing enterprises due to the small scale of operation, technology is weak, inadequate investment in production equipment, resulting in stable production of mechanical products quality and poor reliability. Low quality of the equipment produced concrete products, whether from the appearance of the product, or from the intrinsic quality of products, it is difficult to stably achieve product standard requirements, resulting in block building often cracking, leakage and other problems, plus real break of the progress on the construction of masonry systems and construction technology building structure has not been achieved so severely affected the reputation of block buildings, reducing promote the use of concrete block on the market.
2.2 vicious market disorderly competition leads to low economic efficiency of enterprises
Small business scale, high production costs, but in order to maintain business operations, have to seize the low-cost market. Low-margin products, so that enterprises difficult to invest in research and development and improve product quality, resulting in the development of the enterprise sector into a vicious cycle. As the domestic equipment manufacturers produce larger sized block production line by production capacity constraints, now our annual output reached more than 100,000 m3 of load-bearing block production line most of the imported equipment, so domestic production of concrete products, high-end users are mostly international well-known equipment manufacturers monopoly, resulting in slower economic growth in the domestic equipment manufacturers of concrete products.
2.3 lack of industry self-regulatory mechanism
Some enterprises to maximize profits and to seize the market, trying to cut corners and reduce the selling price, resulting in products machinery and equipment prices continue to decline, even to the point of below cost. Due to the lack of supervision and self-discipline mechanism and management department, some companies in order to rapidly enter the market with quality products at the lowest impact on the market, so that the whole cement products machinery industry showed a disordered state of competition, not only harms the industry, the backbone of the company interests, affecting the healthy development of the machinery industry, cement products, concrete products but also to the majority of users to cause adverse effects, resulting in part of the building design, construction and construction units with the application of green energy saving building materials had a negative attitude.
2.4 capacity for independent innovation is weak
Technological advances need to spend any product of human, material and financial resources, there is no technology research and development and technological progress, there will be no R & D investment in technology innovation. While some businesses to invest some funds for technology development and production transformation, product quality and appearance of the intrinsic quality of some increase, but industry-wide R & D investment in serious shortage. Due to low domestic cement products in the research and development of machinery and technology research institutes, national scientific and technological research and development projects is difficult to project, in the lack of national and local research funding support conditions, their own R & D expenditure and less, leading to industry independent innovation capability is not strong.
2.5 Industry information exchange and statistics work is weak
Although the number of practitioners more business, but in recent years, few industry events organization, lack of mutual communication mechanism between the platform and cement products machinery industry enterprises, affecting the development of industry and technological progress. At present, some companies lose confidence in the industry associations, participation in the activities of the industry are not enthusiastic. Enterprises work of the Association of indifference, leading to industry statistics, and other information industry activities is not up, so that the industry associations to work into a vicious circle. Development of the industry not only to rely on equipment manufacturers, but also to rely on government departments, industry associations, research institutes, parts suppliers and product users, and various efforts to grow and develop. Inadequate disclosure of information industry, it is difficult to obtain the relevant government departments to develop the project in support of policy and technology and science and technology funds, so that the industry into a closed-end self-development state, which neither benefit from the development of enterprises, is not conducive to development of the industry.
2.6 lag product standardization, quality management in the absence of state
Technical standard technical regulations product is the product, the product market stakeholders in business behavior to abide by the rules. Cement products machinery varieties, in addition to GB / T 17047-2008 "concrete products machinery term" and GB / T 8533-2008 "small block making machine," the two standards were revised recently, other product standards in most standard age more than five years, such as JC / T 697-1998 "reinforced concrete pipe hanging roll forming machine" has been 12 years, the standard part of the content has been severely adapt existing products. Some products on the market, although sales have been produced for many years, but the product is still the industry standard in the blank. As product quality supervision on the market is not in place, resulting in fake and shoddy products, shoddy products into the market at low prices, leading to vicious market competition.
2.7 multi-industry enterprise members, lack of cohesion of the industry
Industry business practitioners at least 400 or more, but so far very few members of trade associations, only a dozen companies to join, brought great difficulties to the organization and conduct of industry work.
3 cement products machinery industry outlook
3.1 cement products machinery is a mechanical, electronic, hydraulic, computer controlled, vibration molding, extrusion molding, materials and many other technologies in one of the mechanical equipment, which will be water, cement, aggregate, admixture, admixture composition mix after spreading, molding, ejector, palletizing, transport, maintenance and other craft made of various concrete products. As China's building energy efficiency, carbon emission reduction work vigorously promote the construction and urbanization accelerated, broad market demand for a variety of concrete products, cement products machinery and therefore huge space for development. Cement products is the production of concrete products machinery key equipment, its quality directly affects the product quality and cost. Cement products machinery development should be based on concrete market demand-oriented products, to develop a variety of concrete products to meet the standards of high intelligence, high productivity, high reliability, adapt to different materials, different kinds of multi-function block type structure new products and new technologies. Such as the production cycle time in half, composite insulation block assembly time shortened RMM multifunction block making machine, the device can be flexibly adjust the height of the mold forming by the usual 2 ~ 8cm or 4 ~ 10cm extended to 22cm; in a four-cavity mold 50cm × 25cm in cross section to produce a variety of specifications of products, including imitation rock face, cleavage planes, ordinary brick, imitation cobblestone surface, such as decorative brick, concrete curbs or side stone, dripping along the boards; vibration molding and press-molding two kinds of ramming molding mode can be chosen; stacking two kinds of vertical and horizontal stacking stacking methods to choose from.
3.2 Implementation and buildings with life, both to meet the requirements of energy saving building wall structure can meet the system requirements to achieve the unity of the structure and function of the insulation, that the structural material and insulation material is formed by a composite structural and architectural precast block walls with life sheet (or plate), will be green energy-saving wall materials and building maintenance construction materials latest development. Cement products machinery should focus on the development of wall materials research and development to produce dynamic structural and thermal insulation products, complete sets of equipment and integrated technology.
3.3 implementation of product quality certification, strengthen self-discipline, and promote product quality. Vice Premier Zhang Dejiang on September 2, 2010 the first Chinese industrial product quality reputation forum stressed in his speech: To speed up the integrity of the quality system, speed up and improve the quality and credibility of the regulatory system mechanism, promote the establishment of national, local and industry product quality awards and disciplinary system carry out key industrial product quality evaluation work, encourage trade associations. To promote the implementation of brand strategy, accelerating the development and growth of independent brands, extensive industrial product branding activities in an effort to create a number of world-renowned brand, "Made in China" has become a symbol of quality products. The implementation of product quality certification model is to strengthen the foreign industrial countries product quality and market access common practice management, is to accelerate the industry quality credit system construction, improve the quality of the credibility of the industry regulatory system mechanism, promote the establishment of industry quality award, the implementation of brand strategy, cultivate industry an important part of its own brand. Important Initiatives to implement product quality certification is both to strengthen the industry self-regulation, establish industry product quality control systems and mechanisms, as well as industry associations, "to provide services, build a platform to regulate the behavior of" functional targeting the general requirements to improve the industry product quality, promoting healthy development will be of great significance.
