In domestic has been eliminated. Specific surface area test unified the multi-point BET method at home and abroad, specific surface area measurement standards are developed at home and abroad is based on BET test method, please see our national standard (GB/T 19587-2004) - gas adsorption BET principle of solid material specific surface area measurement methods. Specific surface area testing is actually the more time-consuming jobs, as the adsorption capacity of sample is different, some sample testing may need to spend the whole dayTime, if the test process is not fully automated, the tester can not leave at any time, and should be highly focused, observe the dashboard, control the knob, a little careless will lead to the failure of the test process, which will waste a lot of valuable time of the tester.
F - Sorb 2400 specific surface tester is really able to BET method detection instruments (both direct comparison method), the more important F - Sorb 2400 specific surface tester is by far the only specific surface area of the fully automated intelligent testing equipment, the test results with the international high consistency, the stability is very good also, at the same time reduce the human error, improve accuracy test results.Rough classification of activated carbon
(1) coal-based activated carbon, also known as coal-based activated carbon.
It is a general term for a large class of activated carbon products made of various raw coal through different processes.Coal-based activated carbon can be divided into molding carbon and raw coal direct crushing carbon according to the different manufacturing process.
The former and can be further subdivided into wet molding charcoal (such as tar, papermaking black liquor, such as starch paste liquid adhesive manufacturing columnar, ball charcoal, honeycomb carbon, etc.) and dry molding charcoal (such as join solid bitumen, starch, such as tree powder as adhesive used for Mao briquette made of molding process, tabletting, pelleting and broken charcoal or rules of pelleting shape activated carbon).
Generally speaking, forming carbon can be mixed with a variety of raw coal to adjust the pore distribution characteristics of the final product, so as to obtain some special application performance, and more than 80% of the pore distribution characteristics of raw coal directly broken carbon has been determined by the raw material, so the performance and use is simple.
(2) wood activated carbon.It is mshell/core activated carbon.Such as coconut shell carbon, apricot kernel carbon, peach kernel carbon, etc.(4) petroleum activated carbon.Using petroleum asphalt, petroleum coke as raw materials, made of activated carbon products.resin activated carbon.Using phenolic resin, waste ion exchange resin as raw materials, through a special process of activity.Carbon products, sometimes fibrous carbon also falls into this category.High - definition watermark of cut document under air(6) other small varieties of activated carbon products.coconut shell activated carbon suppliers
Made of animal blood blood carbon, made of animal bones bone charcoal (there is very little, but bone charcoal carbon main ingredients of hydroxy calcium phosphate), with active carbon molecular sieve made of various materials, made of strong base and carbon materials of high surface area activated carbon, is made of organic polymer solution after mold made of special process method of activated carbon, activated carbon aerogels and so on.
Some of them are very small production and dosage, and some are still in the laboratory research stage, so they are included in the category of small varieties of activated carbon products.
