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: highdensity body and low apparent porosity greatly improve its heat conductivity.

3.Newstyle 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

Product Uses

1. Graphite crucible cannot be exposed in moisture, and must be placed in indoor dry place or wooden shelf. Maintain ventilated. Moisture is strictly prohibited. Damped crucible is likely to crack.

 

2. Each crucible, especially damped ones, must be preheated and roasted in drying equipment or next to a ground furnace before use. The roasting temperature should start from a low temperature of 100°C below. Roast it to 150°C at a speed of not higher than 30°C per hour. Preserve the heat for about 8 hours and then dry it. The crucible dried next to a ground furnace should be placed at least for one shift, and often turned to change direction, till workers feel the internal wall of crucible is hot.

 

3. The melting time for the first time should be at least twice of the normal melting time, in order to avoid cracking inside the crucible due to heating up too fast, or even cracking immediately when the fire sets on.

 

4. Handle with care. Falling or shaking is strictly forbidden in order to present cracking. Crucible should be placed below the mouth of furnace to prevent the furnace lid abrading the upper edge of the crucible and thus affecting the capacity.

 

5. Pour out the remaining cold metals inside the crucible after use, and then add new materials. Carefully and gently add new materials into the crucible. Feed materials according to the capacity of crucible. It is not allowed to feed too many materials, in order to prevent crucible from swelling or bursting.

 

6. Knock gently to remove slags and cokes on the internal and external wall of the crucible. Avoid damaging the crucible body.

 

7. In the melting process, do not add chloride solvents in order not to corrode the crucible. For the furnace that uses oil and coal gas as fuels, the oil wind should not reach one part of the crucible directly. Turn around the crucible from time to time, in order to avoid local damage.

 

8. Clamps and other discharging tools should comply with the shape of the crucible. During furnace discharging, remove the cokes on the external wall of the crucible, and lower the furnace temperature; do not discharge at high temperature after stopping blasting. Clamp the upper and middle parts instead of the top of the crucible in order not to damage the crucible. Graphite crucible is used mainly to melt gold, silver and other precious metals.

Q:What is carbon PC?
Polycarbonate (PC), polycarbonate is a molecular chain containing [O-R-O-CO] chain thermoplastic resin according to the molecular structure of the ester can be divided into aliphatic, alicyclic and aromatic type of fat, which has the practical value of the aromatic polycarbonate, and bisphenol A polycarbonate as the most important, molecular weight is usually 3-10 million.Polycarbonate, English Polycarbonate, referred to as PC.PC is a kind of amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastics, has excellent physical and mechanical properties, especially excellent shock resistance, tensile strength, bending strength, compressive strength and high creep; small size is stable; good heat resistance and low temperature resistance, mechanical properties, stability in a wide range of temperature dimensional stability, electrical properties and flame retardant properties, can be used for a long time at -60~120 deg.c; no obvious melting point, a molten state at 220-230 DEG C; the molecular chain rigidity, melt viscosity and high water absorption resin; small, small shrinkage, high precision, good dimensional stability, permeability of films is small; self extinguishing materials; stable to light, but not UV resistance, good weather resistance; oil resistance, acid and alkali resistance, no oxygen acid and amine, Ketones are soluble in chlorinated hydrocarbons and aromatic solvents. They are easy to cause hydrolysis and cracking in water for a long time. Because of their poor fatigue resistance, they are prone to stress cracking, poor solvent resistance and poor wear resistance
Q:Why is ATP the five carbon sugar ribose?
ATP (adenosine-triphosphate) Chinese name three phosphate adenosine, also called ATP (adenosine three phosphate), referred to as ATP, which A said adenosine, T said the number is three, P said that the phosphate group, connecting three phosphate groups.
Q:What can light hydrocarbon carbon five be packed with?
Gas used as a common gas:The light hydrocarbon gas generation device (light hydrocarbon gas generating unit) consists of six basic systems and three safety systems. Includes six basic systems: the host system, fuel supply system, heat system, control system, air system, closed unloading material system. The three major safety systems include ventilation system, lightning protection system, and electrostatic heating system for light hydrocarbon gas.In operation, the working pressure in the gasifier and the static pressure and dynamic pressure of the transmission pipe network are in theBetween 0.01 and 0.02MPa, the normal operating temperature of the gasifier is no more than 45 degrees centigrade, which is lower than that stipulated by the national pressure vessel.
Q:Why carbon 14 can be used to measure the age of matter?
Then, after the death of the animal's plant, because carbon 14 is a radioactive isotope, still continue to decay, death of plants and thus reduce carbon 14 content in a day. 14 the amount of carbon can be determined by measuring the radioactivity. The half-life of carbon 14 for 5730 years, after 5730 years, the amount of carbon 14 only half. Radiocarbon method is the most commonly used method of archaeology, it can be concluded that the year for up to 50000 years.
Q:Benefits of reducing carbon emissions
The researchers then extracted 4 ice ages from 500 to 140 thousand years from Greenland, which resulted in the discovery of TOMV virus in the ice. Researchers say the surface of the virus is surrounded by solid proteins, so it can survive in adversity.The new findings that researchers believe that a series of influenza, polio and smallpox epidemic virus may be hidden in the depths of the ice, the human of the original virus had no ability to resist, when global temperatures rise to ice melting, the ice buried virus in the thousand or more may be raised, forming the epidemic. The scientists said, although they do not know the survival of the virus of hope, or the opportunity to re adapt to the ground environment, but the possibility certainly can not deny the virus back.
Q:What is the cost of carbon emissions?
Q:How do you get DNF advanced furnace rock carbon?
Is there still any carbon in the furnace?After the revision, there is no, where did not sell, the furnace rock carbon has turned into colorless small crystals
Q:Method for determination of total carbon in soil
Q:What are the main factors that affect the strength of carbon fibers?
The main factors affecting the strength of carbon fibers arePAN precursorPreoxidationcarbonizationGraphitizationsurface treatmentCoilingcarbon fibre
Q:The difference between double offset paper and carbon free printing paper
In general, we use office A4, A3, B5 and other specifications of office paper are better offset paper, excellent offset paper to UPM and APP for the domestic leader.55G-140G grams in general, some mills also produce high grams, generally belongs to industrial paper!Carbon free copy is just typing paper and coating. Paint is divided into two kinds, one kind of colored, one kind of colorless.Generally for 37G, 45G, 52G and other grams.
