Introduction of raw materials and use charcoal
export of carbon materials:
1, hardwood, pine sawdust (or branches crushed) or bamboo at the end.
2, hardwood, pine sawdust (or branches crushed) or accounted for most of the bamboo at the end, the rest can be mixed with fir and other softwood sawdust.
should not use the straw like.
barbecue charcoal raw material:
1, the same raw materials and 2011 sonata dvd of carbon.
2, fir, Paulownia and other softwood sawdust (poplar sawdust should not be made pure charcoal grill).
3, accounted for most of the sawdust or the end of the bamboo, the remaining core doped with a small part of the corn on the cob, or cotton straw, or corn stover, or peanut shells,
or sugar cane residue, (straw class to be crushed).
4, hardwood, pine sawdust (or branches crushed) or the end of accounting for a small part of the bamboo, the remaining part of the available corn cob or peanut shells.
5, sawdust or accounted for most of the bamboo at the end, the rest mixed with corn stalks, corn on the cob, cotton straw, peanut shells, bagasse and other mixtures.
grilled Tan materials:
1, described in the above sections of the material.
2, a small amount of sawdust or bamboo at the end, most of the rice husk.
3, most of the poplar sawdust mixed with a small amount of rice husk.
4, all the rice husk.
Note:
1, raw rice husk charcoal grill cheap full lace wig not be done, if hard, neutral 5% wood sawdust mixed with rice husk, barely meets its quality
barbecue charcoal needs. Many are not. The biggest drawback is the rice husk charcoal and not ash gray big.
2, not all to do with raw materials like straw charcoal.
purposes:
Charcoal divided into: high temperature. In temperature. Low temperature.
high carbon: 800 degrees under the conditions of mixing of carbon from the surface smooth, with white, feel heavy, the steel sound, small cracks, shrinkage is good, the char yield is relatively low, exports also called conductive good.
the temperature of carbon: 600 degrees under the conditions of refining, relatively smooth surface, feel heavy, the steel sound, crack less, the carbon rate is relatively high, less than the high-temperature carbon. on the market more popular. Popular at home and abroad welcomed!
low carbon: not to mention temperature, 450 degrees baked the surface is black, non-steel sound, feel heavy, a little crack, shrink is not high, the carbon rate. Used for barbecue and home heating.
lifestyle: barbecue, heating, boilers, moisture, home improvement.
industry categories: metallurgy, chemical industry, medicine, insulation, rubber, etc.
use of the field
(a), industrial areas
1 metallurgical
charcoal smelting of iron generally has fine-grained structure, casting close, there is no crack characteristics, production of pig iron with charcoal less impurities, suitable for production of high quality steel. In the non-ferrous metal production, charcoal is often used as a flux surface, splashing of molten metal can reduce the loss, but also reduce the melt in the gas saturation. A large number of crystalline silicon is also used for charcoal production, but production of crystalline silicon with carbon charcoal head and should not contain too much raw ash.
2. Chemicals
those who require high surface hardness and wear resistance, good toughness and center of all steel products will have to be cementite. To carburization of steel products for the carbon compounds known as carburizing agent. Charcoal as raw material, then add a certain amount of exposure to agent, made of carburizing agent.
charcoal is the best raw materials, trolley bag carbon disulfide, carbon disulfide used to make charcoal, should be hard, great volume, ash and moisture content, fixed carbon content.
(b), the agricultural sector
1. Increase in temperature: drop-off imposed by the soil, due to black carbon particles absorb solar thermal energy, can increase soil temperature a few degrees, to promote seed germination. In particular, can promote the germination of the seeds germinate easily, improve the germination rate.
2. Improve soil: charcoal powder applied in the soil after the root carbon particles can be generated on the surface bacteria, resulting in a plant cultivated for agricultural soil, to avoid the so-called "continuous cropping obstacles." And the carbon of cereals, pulses and vegetable growth, color, taste has improved.
3. To maintain soil moisture: carbon in the relative humidity above 50%, 20% rapid absorption of moisture, can be used to maintain soil moisture. But can also improve soil permeability and drainage, for the benefit of plants, microbes provide a good living space.
4. As a release agent or led light power supply : the use of carbon adsorption capacity, the content of organic fertilizer to maintain a balance, this balance can make or use slow release fertilizer to maintain a considerable time, and not easily With the rain drain.
5. Charcoal can also change the soil pH, increased soil CO2 concentration, adsorption of harmful metals in the soil, increase soil microbial activity.
(c), areas of life
1. People used charcoal for heating, barbecue, hot pot with fuel, especially charcoal, due to a smoke-free, non-toxic, heat, burning a long time, so more and more people of all ages.
2. Charcoal has a myriad of vertical and horizontal holes, these holes with adsorption and release of various substances adsorption function of the material, so people use it as a desiccant. Charcoal bricks with water absorption and moisture absorption is small, significant and high calorific value than the benefits, in the wet, the charcoal will absorb moisture in the dry, it will absorb the moisture release out, so brilliantly played the role of regulating humidity . In addition, the charcoal can eliminate room odors and harmful substances.
3. Porous charcoal plant roots can not only build the necessary moisture to stay, but also improve soil permeability and drainage, micro-organisms for the benefit of the plant to provide a good living space, so the flowers and potting soil braced 5% ~ 10% of the bean-sized charcoal, plants can provide a healthy growing environment. And garden trees, the ability to enhance the strong resistance to pests. Today the concept has begun to pay attention to the decoration environmental protection, natural, health, human characteristics. Decorative charcoal, the use of charcoal interior best backpacks after suction to pay to stay in benzene and other harmful substances, a Cuotu, then bringing out a lush bonsai. You can also adsorb impurities into the fish tank.
4. Charcoal can also help preserve food, such as refrigerators can use it as a deodorant

November 10, the three ministries and organizations open tender, select a number of excellent domestic LED lighting products short-listed companies, and to determine the relevant product specifications and supply agreement price.
Second, the New Deal
property market has been a GMC car dvd gps of the market, buy a house, sellers, rent, real estate, and cover room, are familiar with the market, will lay a little point disadvantage in the price, so very necessary to understand the necessary knowledge. Lighting industry has also been affected because of the property market, unable to control soaring prices, the state began to enforce policies to control up down payment, loan interest also rose, up this natural interest and down payment on the property market impact is not small. A series of comic effect, let the lighting market is lady's handbag lot, but relative to the property market, the impact is, after all, not too much.
Third, the town big "earthquake"
earthquake here that is not natural disasters but man-made! Town's big "earthquake" to the town's lighting business overnight into a panic, town Shunda logistics boss to gamble in Macao, lost hundreds of millions of net worth after the close down, they rely on freight logistics is Shunda The lighting business, almost every company has Shunda logistics "IOUs" arrears, which can be described as badly hurt these small businesses, but also irreparable loss, the only hope for an early catch Shunda the owner to compensation for their logistics, but, how will day? Hope that day come sooner.
four Asian lighting
Guangzhou Asian Games in China and Asia is undoubtedly the event, natural lighting, the Asian Games is a fat, a lot of lighting industry players must fight this piece of meat, of course, to account for the bulk of China's enterprises.
Guangzhou Asian Games on the application of advanced lighting technology more widely, especially LED lighting applications, but also for the prosperous Guangzhou adds infinite charm. Guangzhou Asian Games will not only allow new understanding of the Chinese sports world, but also re-acquainted with the Cooling tower of Guangzhou, which is inseparable from advanced LED lighting, street lights, landscape lights, spotlights, etc., are using more advanced products, but also for the nation brand into the world sounded the assembly number.

Roller bearing failure analysis
excavators used in construction of Three Gorges Dam is imported from South Korea, often occur in the course of the bearing fracture, resulting excavator does not work. Based on the failure of the roller and the bearing outer ring of the microstructure, hardness and other GMC car dvd gps of analysis, the cause of bearing failure.
1? Invalid parts of macro-check
1.1 roller
shown in the cylindrical surface can be seen peeling off the surface resulting from the pits of various sizes , and the face badly damaged, rubbed off a lot. In the pit at the roller along the longitudinal diameter was observed after cut open, inverted triangle bottom right corner of an empty profile, which is where the original crack caused by falling off in the beginning. The upper right corner there is a column extending from the side facing the cracks, about 4.5mm, cracks in the middle, with branches, thin crack direct energetic, tapering tail (see Figure 2), has obvious characteristics of stress cracks.
1.2 bearing outer ring fragments
debris on the outer ring to see some form of fatigue fracture. 0.7mm from the surface of the debris can be seen at a parallel with the surface cracks, cracks intermittent, tortuous, tapering tail. Part of the crack, the crack also has the characteristics of stress cracks.
2? Non-metallic inclusions rating
(1) roller: sulfide l-level, point-like and globular oxides 1.5.
(2) the bearing outer ring: led light power supply a point-like, globular oxides 1.5.
3? Microstructure examination
3.1 roller
3.1.1 Heart Ministry
Ministry of temper hidden heart needle martensite and austenite grain carbide composition.
roller 4% of the original organization of alcohol slightly acid etching? × 500
3.1.2 surface pits surrounding tissue
formed in the roller surface of the peeling Microstructure observation pits found at: pit bottom is a white layer, its width is about 0.18 ~ 0.5mm, length 15mm. White layer has three transverse cracks. Pit close to the bottom of times the outer white layer with a width of 0.40 ~ 0.50mm dark area, dark area is the roller after the original organization. White light and dark intervals organizations quenched martensite, tempered dark hidden needle for the needle a small amount of granular martensite + carbide + retained austenite.
3.1.3 microhardness
three different colors to reflect the lady's handbag of the hardness difference, we conducted a cross-section outside to the inside of the roller hardness test, directly reflects the changes in microhardness indentation size: white layer in the indentation minimum, maximum indentation area dark, slightly lighter color of the original tissue indentation center. Three areas, the average hardness values were: white light district HV0.11264, dark areas HV0.1551, the original organization HV0.1800.
roller pit at the bottom of the white light zone, dark zone, the original organization and microhardness indentation? × 200 4% alcohol, slightly acid etching
3.2 Microstructure bearing outer ring
bearing outer ring of the microstructure of tempered martensite needles hidden a small amount of granular carbides and residual austenite.
3.3 surface hardness
3.3.1 Roller
most point on the roller surface hardness of HRC60 ~ 61 between the vertical but also in some places a line between hardness are HRC56 ~ 57.
3.3.2 bearing outer debris hardness
tested, the inner surface of the bearing outer ring of debris hardness HRC58 ~ 59.
4? Roller surface of the pit Cause Analysis
white light from the quenched martensite zone we can deduce, roller during operation because the weight of each other tight, because Friction generated a lot of heat, extruded parts to form a high temperature, because oil is, therefore, the surface area was re-quenching temperature, quenching to form martensite (white corrosion was bright). As the local temperature effect, so close to the surface of the sub-surface has accepted a temper, so the second roller is higher than the original tempering temperature tempering heat treatment temperature, resulting in sub-surface hardness decreased, easy to peel off, peel off after the formation of the pit, we see the bottom of the pit area is actually a bright white surface residue after peeling down.
As a result, we can conclude: roller on the roller assembly is due to tight crack, hit each other when the pressure of operation, so that local organizational changes have taken place in the great stress under the action of the organization , and therefore has a stress crack cosmetic bag. As the organizational changes made within the roller bearing size larger, outer circle of the bearing surface to withstand a great deal of stress, which eventually split support.

POM POM Typical Applications
injection molding process conditions: drying: If the material is stored in a dry environment, typically does not require drying. Melting temperature: homopolymer material 190 ~ 230C; copolymer material is 190 ~ 210C. Mold temperature: 80 ~ 105C. In order to reduce shrinkage after molding mold can choose higher temperature. Injection led waterproof Switching Power Supply: 700 ~ 1200bar. Injection rate: medium or high injection speed. Runners and gates: You can use any type of gate. If you use the tunnel-shaped gate, it is best to use a shorter type. Polymer materials are recommended for hot runner nozzle. Copolymer materials for use within the hot runner can also use external runner.
chemical and physical properties: POM is a tough, flexible material, even at low temperatures is still very good creep properties, geometric stability and impact resistance properties. POM materials have both homopolymer copolymer material. Homopolymer material has a very good extension strength, fatigue strength, but not easy to process. Copolymers have good thermal stability, chemical stability and ease of processing. Both homopolymer or copolymer materials materials are crystalline materials and are not easily absorb moisture. The high crystallinity of POM cause it has a very high shrinkage rate can be high up to 2% to 3.5%. For a variety of enhanced materials have different shrinkage.
PP polypropylene Typical applications: Automotive (mainly using metal additives PP: fenders, vent pipes, fans, etc.), equipment (dishwasher door gasket, dryer vent pipe, Washing machine frame and cover, refrigerator door gaskets, etc.), consumer goods (such as lawn and garden equipment, lawn mowers and sprinklers, etc.).
injection molding process conditions: drying: If stored properly you do not need drying. Melting temperature: 220 ~ 275C, careful not to exceed 275C. Mold temperature: 40 ~ 80C, recommend the use of 50C. The degree of crystallinity determined by the mold temperature. Injection pressure: can be as large 1800bar. Injection speed: In general, high-speed injection can reduce internal pressure to a minimum. If the product surface defect, then you should use a high temperature low-speed injection molding. Runners and gates: For cold runner, the typical flow channel diameter is 4 ~ 7mm. Recommend the use of whole body is circular sprue and runner. All types of gates can be used. The typical gate diameters range from 1 ~ 1.5mm, but can also be used as small as 0.7mm gate. For the edge of the gate, the minimum wall thickness of the gate should be half the depth; minimum wall thickness of the gate width should be at least twice. PP material can use the hot runner system.
chemical and physical properties: PP is a semi-crystalline materials. It is to be more rigid than PE and has a higher melting point. As the type of PP homopolymer is higher than the temperature above 0C is very brittle, so many commercial PP material is added 1 to 4% of the random copolymer of ethylene or a higher ratio of clamp-stage ethylene content copolymer. PP copolymer-based material has a lower heat distortion temperature (100C), low transparency, low-gloss, low rigidity, but a stronger impact strength. Strength of PP increased with increasing ethylene content. Vicat softening temperature of PP is 150C. As a high degree of crystallinity, the surface of the material properties of stiffness and good resistance to scratches. PP does not exist environmental stress cracking problems. Typically, the use of glass fiber, metal additives or thermoplastic rubber modified PP method. PP turnover ranges from 1 to 40 MFR. Low MFR better impact properties of PP material, but to extend the lower intensity. MFR for the same material, copolymer-based homopolymer-type intensity ratio is higher. As the crystal, PP shrinkage rate is very high, typically 1.8 to 2.5%. And uniformity of shrinkage in the direction other than the PE-HD materials are much better. With 30% glass additive can make shrinkage to 0.7%. Homopolymer and copolymer type of PP-based materials have excellent renault megane car gps dvd to moisture absorption, resistance to acid corrosion, anti-solubility. However, it aromatic hydrocarbons (eg benzene) solvents, chlorinated hydrocarbons (carbon tetrachloride) solvents such as no resistance. PP did not like PE still has a high temperature oxidation resistance.
PPE polypropylene Typical Applications: Anal Products dishwashers, washing machines and other electrical equipment such as the controller shell, fiber coupling and so on.
injection molding process conditions: drying: It is recommended prior to processing for 2 to 4 hours, 100C for drying. Melting temperature: 240 ~ 320C. Mold temperature: 60 ~ 105C. Injection cool schoolbags: 600 ~ 1500bar. Runners and gates: You can use all types of gates. Particularly suitable for use handle-shaped gate and fan gate.
