Furniture possession of formaldehyde, costs are tricky
Home decoration, plywood and their products, adhesives, interior paint, wood furniture, wallpaper, Qiangbu Pihui with 107 glue, 804 glue, plywood and flooring with purpose adhesive, foam, paint, etc. are likely presence of formaldehyde and volatile out. However, these materials release formaldehyde, with ordinary wood-based panels used for home improvements, its formaldehyde emission dwarfed. Ordinary wood-based panels fundamental reason for the sustained release of formaldehyde, wood-based panel manufacturing process requires the use of aldehydes adhesives, such as urea-formaldehyde resin. The adhesive itself is directly formaldehyde and urea compounds. Because of the low price, good bonding effect, so a lot of use in the manufacturing process of wood-based panels. Such colloidal biggest drawback is that under natural conditions will continue to spontaneous decomposition restore, re-release of the free formaldehyde. And in the hot and humid environment, such decomposition, deliquescence reaction rate will double.
The Shanghai Furniture Industry Association Secretary-General Xu Guan Rong told reporters: "furniture excessive levels of formaldehyde, mainly due to the machining process, once the plates, glue, paint, formaldehyde content can not be guaranteed, the formaldehyde content of the furniture will not consciously excessive. in order to reduce costs, companies buy the inferior plate. environmentally friendly materials formaldehyde content is low, but the cost is relatively high, and low-grade sheet, the difference of each block in the range of 60-100 yuan. "According to the reporter, the most important raw material in the sheet metal furniture sub-plate, particleboard, MDF and other varieties, are generally bonded by glue made itself contains a certain amount of formaldehyde. Sheet in line with national standards E0, E1, E2 three kinds, where E0 is the most environmentally friendly, lowest formaldehyde content, of course, cost is the highest.
Currently, in accordance with state regulations, the furniture formaldehyde emission should be less than 0.15mg/m3. Xu Guanrong "Sometimes manufacturers purchasing more environmentally friendly E0, E1 sheet, but in the process, because the glue, paint, and other factors can also cause high levels of formaldehyde, the Shanghai Committee Secretary-General of raw materials should be Yang told reporters:" Even put an end to the use of green building materials also can not guarantee that the high levels of formaldehyde, although the company has the certification standards of the material, but the gatekeeper detection lax in the production process, but also can not guarantee that it is environmentally friendly. "
In this regard, it should be out again that the government and enterprises should work together with the management from the source of high levels of formaldehyde. The Xu Guanrong called on manufacturers to enhance the sense of responsibility and environmental awareness. At the institutional level, Lu Weiguang hope that the country will be united formaldehyde testing equipment and methods, enterprises and cities, the city and the city's testing equipment and methods to reduce the excessive formaldehyde caused by human, real consumer confidence.

The Common Sense of Gas Stove
Method to Determine Whether the Gas Stove Leaks
First, configure the appropriate amount of soapy water (preferably dense), it is used for leak detection. Second, open the vent valve to smooth the flow of the gas source. Third, check whether the connection of pressure relief valve of gas stoves leaks (only applicable to liquefied gas): lightly moistened with soapy water, drops on the connection of pressure relief valve and the gas tank, and then observe whether there are air bubbles, if the bubble is generated, you need to replace the pressure relief valve. Fourth, check the connecting hoses are leaking. Fifth, if the above method is still not able to lift the leakage phenomenon, you need to site maintenance.
The Role of Gas Stove Damper
When you hold a gas stove, there are two a handle-like iron pieces at the connection of burner nozzle and burner, one is for regulating small fire, another adjusts big fire; they are all close to the burner through the spring, gently toggle the handle and you can adjust the size of the air intake hole, thereby changing the state of the flame. When the combustion is unsatisfactory, such as the yellow fire, black fire, flame is too large or too small, or the combustion noise and tempering phenomenon, by adjusting the damper of kitchen hobs at the size of the air volume o achieve ideal combustion conditions
Why Does the Gas Stoves Has A Blue Flame?
If the main part of the flame is blue, yellow and red flame are just floating in peripheral part, this is not a product issue, but caused by temperament impurities, while the main part of the blue flame completely ensure full combustion and thermal efficiency, does not affect the performance of the gas stove.
Why There Will Be Red Flame in the Gas Stove? First, gas reason: when there are too much water in the combustion gases or contain too many impurities, it will make the color of the flame red. Second, dust reasons: When there is dust in the house or the amount of moisture and oil and gas in the air increases in cooking, but also prone red flame. Third, Damper reason: When the position of the damper is poor, such a situation may occur, and then simply adjust dampers. Fourth, the support pot rack reasons: support pot rack surface enamel will become red when heated at high temperatures, because the enamel of special material will appear around the branch pot rack flame is red, which is the color of the metal ions at high temperatures. So the red flame is not caused by the stove out of the problem, but due to the above reasons, normal use will not be affected, nor the health hazards.

Introduction of SMD LED
Notes for Welding SMD LED
First, clean do not use unknown chemical liquid to clean SMD LED, because unknown chemical liquids may damage SMD LED. When it is necessary to wash it, immerse the 5050 SMD LED in alcohol for less than 1 minute in the normal room temperature, and naturally dried it for 15 minutes, and then you can begin to use it. Second, moisture proof packaging is used to avoid the moisture of product during transportation and storage, SMD LED is packaged with moisture-proof aluminum packaging bags, and there are desiccant and humidity card in the bags, the desiccant mainly control the humidity of packaging bag and humidity card monitors SMD packing humidity. Third, the manual welding process, the soldering iron must be less than 25W, the temperature must be kept below 315 °C and the welding time cannot be more than 2 seconds. Furthermore, soldering iron cannot come into contact with the epoxy part. When finishing the welding, it cannot be packaged until its temperature is below 40 °C after it cool down.
The Features of SMD LED
The emitting principle belongs to a cold light emitting rather than lighting by heating or discharge, so the component life is about 50 to 100 times than the incandescent bulbs, it is about 100,000 hours. It needs no warm lights and the lit response speed is faster than the general electric light (approximately 3 to 400ns), the same with LED diode. Electro-optical conversion efficiency is high and the power consumption is small, it saves about 1/3 to 1/20 of the energy consumption than the ordinary bulb. In addition, it has excellent shock resistance, high reliability and low cost of the system operation. Its size is small and thin, and its weight is light, without the limitation on the shape, so it is easily made into all kinds of applications.
The Purpose of SMD LED Package
SME LED must be packaged, because the package can protect grain and lines, to avoid disconnection, moisture or damaging the grain. It can Increase the light output of the grain, and reduce the proportion of the light of total reflection of the grain surface. It may design the specific light emission angle and brightness analysis. Furthermore, it can fine-tune the color of LED. The package makes it easy to be hold and installed. Last but not the least, it can meet the photoelectric of the various applications and the size requirements. Therefore, we should pay more attention to the package of SMD LED, for it plays an extremely important role in protecting and optimizing the light.

Furniture industry _ the industry dynamic inter-provincial survey report
The comic broke of Da Vinci event is certainly a lesson in the furniture industry in 2011, history, certainly some of the practices of the Da Vinci company not only did not make their own to please public relations crisis, but into comic crises. I believe that the Da Vinci family during the crisis, there are some major decisions right might be able to help the enterprises out of the crisis.
First of all, most in need of an urgent solution for the crisis event qualitative issues. A possible qualitative quality problems of goods sold: Da Vinci furniture can not be denied; enterprises recognize the courage to admit their mistakes is responsible performance, to trace the source of the problem and find a solution to give consumers confidence in reply. The possible qualitative Another enterprise with local goods instead of foreign brands, through a special operation to deceive consumers, is great integrity issues. In media communication will be by Leonardo da Vinci, da Vinci's strategy is to describe the non-authenticity of the second possibility.
But I believe that, in the event of the crisis, both qualitative may exist, just the pros and cons, which one is better, respectively. If enterprises with local high-quality products to replace foreign brand goods, alternatives better than the quality of foreign goods, then the consumers, in terms of business ethics aside, but is a value. Really quality merchandise, the crisis also this kind of occurrence it? So, from the consumer's point of view in terms of standing, the core of the crisis is the quality of the goods issue. This problem, even if Da Vinci joint agent brand publicity, but also can not cover up. Admit, acknowledge the problem of the quality of the goods, and admit that there are problems in the procurement chain is the inevitable way out, is also a top priority. Response on this issue later on enterprise against greater.
Secondly, the spread of the right to address the issue of corporate brand value. The the DaVinci furniture brand positioning high-end, meet many domestic well-off grade crowd identity and enjoy life needs. The existence of the business for many years, a large number of loyal customers; injured customers whatever the reason, after all, is one of the few. Enterprises can ask the consumers themselves to speak, loyal customer choice is correct. If the companies do not do damage to the brand image, the ripple effect will be wise tarnished image of loyal customers. If negative value to customers God bring the brand value of the enterprise will lose the meaning of existence. Leonardo da Vinci in the convening of the media communication will not to control this problem, resulting in media communication will become injured consumer dissatisfaction catharsis seriously out of control.
Third step to explain the fact there has been in the furniture industry: the production of Italian furniture. Many small and medium-sized furniture factory is a well-known brand in the Italian furniture industry specialization supply phenomenon is widespread. Grasp of design, furniture brand factory grasp the quality of the professional division of labor, foreign well-known furniture brand with small and medium-sized furniture supplier is a common phenomenon. If the problem is really there, that is the gatekeeper of the procurement chain. Expose industry facts, not to evade the issue, but to solve the problems of domestic public misunderstanding caused by asymmetric information. Fourth step of
, be sure to welcome media monitoring, media to monitor their own improvement. On the one hand, the Da Vinci furniture sales brand sales of goods of quality assurance mechanisms, need to come up with clear and targeted measures, to prevent problems from happening again; the other hand, the problem of quality assurance services to consumers. The media is not the enemy, but rather the development of enterprises to promote the power of. If the pendulum is not correct mentality in this regard and can not be exchanged to itself reborn.

Basic Knowledge of CNC Cutting Tool
Commonly Used Material of CNC Tools
Materials CNC tool is broadly divided into the following categories: high-speed steel, carbide, cermet, ceramic, polycrystalline cubic boron nitride, and polycrystalline diamond. Here mainly mention the ceramic, the time of the use of ceramics for the cutting tool is earlier than carbide, but due to their brittleness, the development is very slow. But since the 1970s, it still gets a relatively fast development. There are two major lines in the ceramic tool materials, namely alumina-based and silicon nitride department. Ceramics, as a cutting tool, have the advantages of low cost, high hardness, high temperature performance and a good prospect.
Category of CNC Cutting Tool
According to cutting exercise and the blade shape, CNC cutting tool can be divided into three categories. The general-purpose tool, such as turning tools, planer, milling cutters (excluding forming lathe tool, shaping the planer and forming cutter), boring tools, drill bits, reamers, reamers and saws, etc.; the forming tool, this type of tool blade has the same or nearly the same shape with the workpiece cross section, such as forming turning tools, molding planer, shaping cutters, broaches, tapered reamer and threaded processing tool; The generating tool is to use the generating method to process gear tooth surface or similar artifacts, such as hobs, shaper cutters, gear shaving cutters, bevel gear planer and bevel gear milling cutter. Cutting tools, if classified in the form of the workpiece surface, can be divided into five categories. Cutting tools used to process a variety of the outer surface are including turning tools, planer, milling, outer surface pull knife and rasp; hole-making tools, including drills, reamers, boring tool, reamer and the inner surface of the broach; the thread processing tools, including taps, dies, thread cutting head automatically opening and closing, thread turning and thread milling cutters, etc.; and the gear cutting tools, including hobs, shaper knife, shaving cutter, bevel gear processing tool; the cutting tool, including inserts tooth circular saw blades, band saw, bow saw, cut off lathe tool and blade cutter.
Alloy End Mills
The carbide end mills are the milling cutter made with carbide material. If you want to learn carbide cutters then you need to know what the cemented carbide is. Cemented carbide is based on the high hardness micron level refractory metal carbide (WC, TiC) powder as a main component, and powder metallurgy products uses cobalt (Co) or nickel (Ni), molybdenum (Mo) as a binder, fired in a vacuum oven or hydrogen reduction furnace. Carbide cutter is mainly divided into: solid carbide tools, carbide straight shank slot cutters, carbide blade cutter, carbide spiral drill cutter, carbide machine reamer cutter, carbide end mill and carbide ball end mill.

Furniture testing standards vary authoritative environmental certification show evolved into
"Formaldehyde content can be zero, but there is no other harmful substances?" Zhang Hairong, said the environmental protection furniture equivalent pure environmental protection, zero pollution, so the idea is not realistic, "regardless of the plate, cloth, leather, or bonding agent, there can be no concept of pure green. "
Therefore, Zhang Hairong, some sellers in order to cater to consumers' environmental psychology, saying sales of furniture "zero formaldehyde" green furniture brand furniture can not do it now, zero formaldehyde, just the content of formaldehyde meet the relevant standards.
Zhong Hua benefits Fidel young children mattress view, the so-called "green furniture" covers three meanings: First, the furniture, the materials in line with national standards; in the manufacture and use of the process will not damage the health, waste products will not pollute the environment; parts easy disassembly decomposition, ease of recycling, processing, reuse. If you can meet the above requirements, you can claim to be environmentally friendly furniture.
"Since a large number of businesses are choosing promotional selling point as the use of environmentally-friendly furniture, as evidenced by the development of environmentally friendly furniture is the trend." Zhong Hua called on relevant government departments should develop standards for green furniture businesses are rule-based, sustainable development.
