herical activated carbon applications
1. Solvent recovery
The industrial sector to use a variety of organic solvents, in the quality products come out at the same time, some organic solvents are emitted into the atmosphere, the formation of pollution, resulting in profound social problems. To this end, a Japanese chemical engineering company has developed the use of spherical activated carbon, solvent recovery unit, at home and abroad electrical, chemical, automotive, pharmaceutical and other industries, has established more than 400 sets of equipment. Energy-saving ̖̖, no drainage solvent recovery and deodorizing device, get everyone''s praise.
2. The gas treatment filters, etc.
Spherical activated carbon because of its high purity, low dust, spherical, low pressure loss characteristics, as well as super-purification capacity, has been in the semiconductor industry, clean room filters adsorption materials, electronic devices such as gas processing, automotive interior environmental purification by adsorption the areas of materials used.
3. Water Treatment
Activated carbon adsorption treatment is a branch of water treatment, as in recent years, water pollution and measures to strengthen the management on the demand for activated carbon are also increasing. In the activated carbon adsorption treatment, fluidized bed display excellent decontamination efficiency of the way in a fluidized bed is used spherical activated carbon as adsorbent in water treatment plants has played more than 10 years effect. In addition, the use of its high purity, low dust, wear-resistant characteristics of spherical activated carbon manufacturing plant in water and drainage treatment plant is also being used.
4. Other applications
Refining chemicals used absorbent
Adsorption of catalyst support materials used in
Trapping material used for gas analysis
Filling material used in gas chromatography
Adsorption material used in shoe soles
Sterilization equipment and other materials used
Smoke filter
Health care products, gifts
5. Drugs
Spherical activated carbon for chronic renal failure (CRF) The role of mechanisms:
Since 1983, it was the drugs were systematically pre-clinical and clinical pharmacological effects and mechanisms of research.
The mechanism of spherical activated carbon
Pre-clinical studies, mainly by rodents and non-rodent animal model of chronic renal failure making,
Of the subjects of drug testing and research.
The test results showed that the drug through its adsorption
Improve the renal failure animals
Serum creatinine clearance rate, clearance of uremic toxins, increase glomerular filtration rate, renal plasma flow,
Improve glomerular hypertrophy, renal mesangium in the polymer material and calm rate, glomerular sclerosis and so on.
In animal experiments, based on original research and development units also from October 1978 onwards,
The drugs used in clinical trial patients with renal failure, the safety and effectiveness of test subjects through the thousands of cases,
The results show that this product by the adsorption of renal failure in patients with gastrointestinal tract in uremic toxins,
To improve the clearance rate of serum creatinine, blood urea nitrogen content,
Delaying chronic renal failure (CFR) of patients started hemodialysis time,
To improve the symptoms of CRF patients with uremia.
This product is the difference between ordinary activated carbon adsorption in addition to a large quantity of toxin, the
Also has digestive enzymes in the digestive tract absorption is small,
Greatly reduced the chances of side effects resulting from constipation.
When the human body, the lesions occur in the kidney, the glomerular filtration function and the gradual loss of necrosis, a new glomerular been added. As the human body is a certain number of glomeruli, with time, gradually reduce the number of glomeruli. When the number of glomeruli in vivo less than 50%, the renal disease patients entering decompensation period, kidney function started to decline canisters, blood toxin concentration. Elevated blood concentrations of toxins in turn increase the burden of glomerular filtration, thus accelerating glomerular necrosis, thus creating a vicious cycle to accelerate patient access to uremia, as shown in Figure 2. Occurs when the body is kidney disease, especially in the decompensated phase, when they enter the oral spherical activated carbon absorption in the gastrointestinal tract through the intestinal wall into the gastrointestinal tract of toxins (as shown), and eventually excreted with the feces, thus part of the play function of renal excretion of toxins, reduce toxins in the blood concentration of toxins in the body slow accumulation rate, for the progress of chronic renal failure to suppress the extension into dialysis time, and to improve symptoms of uremia
2000 Kremezin particles in Japan since the second year, has doubled sales on the current annual rate of 10% is still growing. The end of 2004, its sales reached 142 tons, with sales of approximately 222 billion yen (about 1.5 billion yuan). It is estimated that at present there are about 300,000 Japanese patients with chronic renal insufficiency, of which about 5 million people taking the drug for the improvement of uremic symptoms, delay dialysis treatments in period. Chinese patients with chronic renal failure statistics are still incomplete, but according to reports, every year about the new chronic renal failure and received dialysis patients is about 1 million people. With chronic renal failure patients an effective treatment for kidney dialysis, governments and individuals every year for kidney dialysis, a large medical expenses, it was reported that the Japanese Government''s annual medical expenses for dialysis into 90 billion dollars. Spherical activated carbon can effectively relieve chronic renal failure patient''s symptoms, slow dialysis in period, reducing the government and the economic costs of the individual patient. Kremezin particles in Japan, priced at ¥ 156 per gram (about RMB 10 ~ 12 million). At present, China has the kinds of drugs in generic drug R & D success and are already undergoing clinical trials. |
