Product Description:

Features 

1.Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure.

2.High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity.

3.New-style materials: new heat conduction material ensures faster heat conductivity and pollution-free product, reduces adherent slag.

4.Resistance to corrosion:better anti-corrosion than normal clay-crucible.

5.Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime.

6.High-strength: high-density body and logical structure make the product better compression property.

7.Eco-friendly: energy-efficient and pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment.

8.Multi-function: Can be used in induction graphite crucible furnace

Q:What is the concept of carbon equivalent? What is the relationship between carbon equivalent and weldability?
In order to facilitate the expression of strength properties of these materials and welding performance simply to carbon equivalent to said through the statistics of test data.
Q:Is badminton material good with carbon fiber or carbon fiber + resin? Five
All carbon fiber is good. The resin is only used for the badminton line, not for the racket.All carbon fiber material, is the most important material for badminton racket, all carbon fiber, good toughness, but also take into account the light performance.Carbon composite fiber, that is, in the carbon fiber added ordinary metal elements, such as aluminum, this material is relatively heavy, and toughness is not all carbon material.The best one is the carbon fiber material of racket frame which added to the rare metal, adding rare metal frame strong resilience, stability is better, and more suitable for double play.
Q:Can carbon in barbecue cause cancer? Can carbonated food cause cancer?
Eat barbecue are carcinogenic, because the meat directly on the heat under the grill, the decomposition of fat droplets in the charcoal, and then with the meat proteins, it will produce a carcinogen called benzopyrene. Experts explained that if people regularly eat food contaminated by benzopyrene, carcinogens can accumulate in the body and cause stomach cancer and bowel cancer.
Q:What is carbon emission and what harm does it do? How can carbon dioxide be prevented?
The thermodynamic partial oxidation to synthesis gas, there is a relationship between O2 and CH4 mole ratio on deposition temperature, in the actual production is done, according to raw materials the ratio of the different temperature conditions of the appropriate choice, or according to the different ratio of raw materials, select the appropriate reaction temperature, to minimize coking of the catalyst.According to the metal partial oxidation of methane to Syngas in the catalyst, at different temperatures of pure CH4 and CO in nickel catalyst coke rate, found under the temperature of 1123K, 2CO is CO2+C rate than methane dissociation rates were slow 20 times and 5 times, which indicates that the catalytic pyrolysis of methane is the main way to deposit formation.
Q:Helmet material: ABS composites, FRP, carbon fiber, what are the differences? How to tell good from bad?
ABS resin is one of the five major synthetic resin, impact resistance, heat resistance, low temperature resistance, chemical resistance and excellent electrical properties, but also has the characteristics of easy processing, product size stability, good surface gloss, easy coloring, painting, but also the surface plating metal, electroplating, welding, hot pressing and bonding the two processing, widely used in the industrial field of mechanical and automotive electrical and electronic instruments, textiles and construction, is a very widely used thermoplastic engineering plastics.Materials (Composite) is a material consisting of two or more than two different materials which, in physical or chemical ways, macroscopically form new properties. Various materials in the performance complement each other, and produce synergistic effect, so that the comprehensive performance of composite material is better than the original material, and meet a variety of different requirements. The matrix materials of composite materials are divided into two major categories: metal and nonmetal. Metal matrix commonly used aluminum, magnesium, copper, titanium and its alloys. The non-metallic matrix mainly includes synthetic resin, rubber, ceramic, graphite, carbon and so on.
Q:What is latent carbon?
If there is already one or more chiral centers in the molecule, the chiral center of the molecule will result in a non enantiomer, for example:The C-2 2- hydroxybutyric acid is chiral, is a chiral molecule.C-3 is connected with the two hydrogen atoms of the same and two not the same group, it is a potential chiral carbon atoms. When a hydrogen atom on the C-3 is a different from the other three atoms or groups (such as OH) instead, it generates a new chiral carbon atom. This new chiral carbon atom has two opposite configuration, and the chiral carbon atoms of the original configuration is the same, so the product is replaced by the diastereoisomers, their output is not equal, is often far away.This is not directly after separation of chiral molecules in latent chiral carbon atoms into chiral carbon atoms, and generate different amounts of stereoisomers called "chiral synthesis" (chiral synthesis), also known as "asymmetric synthesis" (asymmetric synthesis).
Q:How about Zonta carbon technology
Never go, unless you are a bully, and will mix, inside mess
Q:Who can explain that bare feet on fire carbon don't burn feet?
These two substances are edible, containing in the mouth is naturally very safe, plus cinnabar is red, and dissolve it in the water, this red holy water is more mysterious.From time to time to the fire scattered in the "law" law of water spray powder "and" add before have feet soaking in full dissolution of cinnabar and borax "holy water", which is on the fire and carbon between your feet to form a thin protective layer of "sand", which has scientific significance, is is that all the fairies and the real reason for lossless hair or.The world is material. A scholar once said, "what is a ghost?" Some phenomena that cannot be explained by science are ghosts in our hearts. If we can continue to search in the way of science, ghosts will leave us!
Q:What does "2T-250,1U-200@300" and "1Y-100" mean in carbon fiber cloth reinforcement?
Upstairs to a very comprehensive, I made of carbon fiber cloth
Q:What should I do when carbon monoxide leaks?
Be careful not to let their affected by the cold, otherwise, may make the body temperature decreased cardiac arrest. If the poisoned person can drink, can feed the hot tea and sugar, to keep warm, cold towel head can not be used, but can not pour cold water. Poisoning breathing difficulties or just stop breathing, artificial respiration should be immediately closed chest cardiac massage or first aid, and to call the ambulance the unit, or ask the neighbors to help, send the patient to the hospital for treatment.
