Try to become the industry pacesetter by innovation First-class quality and service cast first-class enterprise, this sentence is particularly important in the construction machinery industry; in recent years, China s mining machinery industry maintains a rapid development momentum. Once upon a time, the International Heavy giants with a strong financial and technical strength monopolize the Chinese market; but now, our domestic heavy industry enterprises has already got the market strength in the capital and the scale to break the monopoly of foreign brands; as a private enterprise, Hongxing Industry shows powerful advantages with the institutional advantages, quality and service competitiveness. From its inception, Hongxing Heavy has undergone several stages: construced the first its own production base; initially the company s products and scale system perfected; introduced talent and expanded the base to start the development of large-scale production; and to 2008, it has got a qualitative leap in the company’s management or strategic planning level whether; 2010 the company has reached the size of the group of companies to produces large and medium-sized series of crusher, sand maker and milling machine. These achievements are closely related to the policies of the company; There are mainly three aspects enable Hognxing stand out in the fierce competition in the market: reputation, service and quality. National mining machinery industry market is not specially in order, without specific industry standards, so reputation is particularly important. In service level, both in the pre-sale, and aftermarket, it provides customers with comprehensive, thoughtful, convenient and efficient service. The technical quality of the product maintains the industry-leading level; quality of the product quality reaches the level of customer satisfaction. Quality products can not be separated from technological innovation, Hongxing Heavy attaches great importance to investment in research, every year, more than 6% of the sales profits are invested in research and development, we have established strategic partnerships with more well-known colleges and universities to jointly research and develop projects. primary crushers: ore beneficiation:
Sandwich panels – a modern construction material, without which it is impossible to imagine both civilian and industrial construction. It's lightweight design, easy to install and incomparable to any material in their heat and sound insulation properties (100 millimitrovaya panel with mineral wool insulation on its thermal insulation properties of 7 times the brick wall of the same thickness). The main purpose of the sandwich panels – Protecting designs in the construction of prefabricated buildings. Sandwich panels are of the following types: wall, roof, ceiling (used in decoration) partitions, including fire; facing (used in the reconstruction and insulation of old buildings) panels for cold rooms. The application of sandwich panels: industrial buildings, warehouses, service centers, shopping malls, sports facilities, medical complexes, including "Clean rooms", the building-"fridges"; agricultural buildings, reconstruction of buildings and structures.
The design of multi-layer sandwich panels, as follows from name. The most common type – frame consisting of two shaped steel sheets, filled with insulation. The use of profiled steel sheet attached to the panel rigidity. As a rule, ends represent a kind of "lock" that makes it easy to mount, and in some designs to avoid the so-called "cold bridges". The most common insulation sandwich panel mineral wool, polystyrene, polyurethane foam. Mineral wool – a natural material made of silica rock melts the synthetic resin binder, and polystyrene foam – plastics. Heaters fairly waterproof, but the mineral wool as the absorbent material, yet is able to absorb moisture, which greatly reduces its thermal and sound insulation properties. To reduce this gap by manufacture of sandwich panels used vapor sealing materials.
Sandwich panels with polystyrene insulation from completely moisture resistant. The thickness of sandwich panels ranged from 50 to 300 mm, depending on the application and region-building. Weight sandwich panels as thick as 100 mm of polystyrene insulation with 1.5 easier panels with mineral wool insulation. This figure makes polystyrene foam insulation panels with a more attractive when construction, as reduced transportation costs and the load on the foundation of the building. The difference of heat-insulating properties of different insulation is low, it varies between 15% and EPS retains heat better. The level of fire resistance is higher in the mineral wool: under high temperatures, it can break down, but does not support combustion. Perhaps, therefore, a sandwich panel with insulation that are most common in Russia.
Parquet lacquers – have the best resistance to wear, or everyday language – to wear. They are not resistant to the effects of sun, rain, not willing to strong temperature variations. But in the case of a fall on the floor various household items coating compositions based on such an honor to stand the test. Produced types of parquet lacquers, which are composed of polyurethane resin coating to give elasticity. This addition allows withstand seasonal or age-related strain of the tree and at the same time helps to avoid cracking of the wood surface. Abbreviations used (for domestic varnishes): AC – alkyd, acrylic, AK – polyacrylic, AU – Alkyd-urethane, BT – Bituminous, VA – polyvinyl acetate, GF – glyptal (used to produce primers GF-021), MA – oil, MCH – Urea, NC – nitrocellulose, diluted with solvent 646, PE – polyester, PF – pentaphthalic, SD – Polyurethane, HV – perchlorovinyl, FL – epoxy, EF – epoksiefirnye. In addition, one of the characteristics of a gloss varnish to%.
Gloss varnish has glitter – 80-90%, semi-gloss – 40-50%, 10-15% Honed. Tips: – To cover with varnish floors, which are in use will be subject to heavy load, it is better to use polyurethane varnish. They are more resistant when compared with acrylic or alkyd. – To avoid loss of color and all sorts of troubles related to color the surface, which may occur over time, we recommend you first soak the work surface antiseptic, and other protective compounds before applying the lacquer itself. – The application of additional layers of coating gives better resistance to external influences. So it is better to apply two or three thin coats than one thick.
– The surface, and it is very important to be 100% dry, flat, buffed from grease recommended by the solvent. The surface should be dust and dirt. – For the best quality and smooth coating to use polishing. The first layer of varnish can be sanded grit abrasive sandpaper fine. This will improve the quality of adhesion to subsequent layers. – Remember that many lakes, including two-component, are toxic! Before applying please read the instructions and, if necessary – use personal protective equipment: rubber gloves, respirators and goggles. To varnish and paint in a closed unventilated room is dangerous!
Almost all alarm systems are designed in a modular fashion, so some of the architectural features of the premises require additional devices in the warning system. These devices are used for emergency broadcasts, quality or disruptive power of sound. In stores and office buildings fire alarm system can generate enough cozy atmosphere, soft music, or lose a different ad kind. If a sensor alarm signal is received, the music stops and the warning system will play an emergency message. Setting priorities in this order is very important for safety warning systems. In the market there are plenty of warning systems, designed for different situations and with different functions.
But it is still possible to allocate some blocks that are common to all systems on alert fire: – digital alarm system is controlled by the computer through the matrix block, which is part of the system – power-switching signal – equipment to amplify the signal, which come from the source (Eg translational microphone, mp3 player, etc.) – radio microphones, which are used to working remotely Manager – speakers (in the horn performance, wall and ceiling speakers). If we divide the system alerts the principle of operation, they are local and centralized. Current warning systems must comply with certain rules and regulations. These rules are contained in several documents (regulations). In addition to regulatory documents they must be certified on a mandatory basis in compliance with Ukrainian standards of fire safety. The recommendations of the sound design of the buildings said that the warning system is better to use written advance the message, because during an emergency voice narration can be undisciplined. Ideally, the vote must be neutral and calm, so that will suppress panic. Message should contain necessary for evacuation information. Only with the correct use of alarm systems will be able to perfectly fulfill its role in emergency situations in case of fire or other disaster.
