1. The ratio of hydrogen oxygen atoms in the carbonization is 2:1.

It refers to a pyrolysis technology for the purpose of preparing corresponding carbon materials under the condition of lack of oxygen or oxygen. The process is synchronized with the decomposition of biomass, wood fiber and lignin.

2. Abbreviation for carbonation carbonation.

3. Carbonization and carbonization in the carbonization process.
The process uses a chemical process combined with mechanical treatment to remove the vegetable cellulosic material from the wool. Sheep often adhere to a variety of plant seeds such as grass seeds, grass and leaves, if not removed will cause many difficulties for textile processing and affect product quality. According to the acid resistance of the wool and the acid resistance of the plant, the plant-containing wool is immersed in the dilute sulfuric acid solution, and the excess acid is removed, dried and baked at a high temperature, so that the main component of the plant material is concentrated in the acid solution. Dehydrated into a blackened brittle carbonaceous material. This is extremely easy to remove by mechanical crushing into powder. Plant carbonization requires a certain amount of acid absorption, and larger grass seeds are often difficult to carbonize due to the inability of the acid to be immersed. The amount of acid absorption increases with the increase of acid concentration and temperature, and the relationship with acid picking time is: the acid absorption is fast at the beginning, and the acid absorption amount does not change much after a few minutes. The wool fiber has acid resistance in the lower concentration acid, but as the acid concentration, temperature and pickling time increase, the acid absorption of the wool also increases. When the acid content of the wool exceeds 8%, the fiber is damaged and the strength is remarkably reduced. In order to protect the wool fiber from chemical damage, a surfactant is added to the acid solution during carbonization, and a non-ionic or cationic active agent is generally used, so that the acid liquid is easily spread on the wool fiber, and the distribution is uniform, and the wool is avoided. Excessive acid acid damage; reduce the surface tension of the acid solution, improve the acid removal effect of the pressure roller, reduce the moisture content of the wool, thereby improving the drying efficiency and reducing the damage of the wool during drying. After baking and removing the impurities, the acid on the wool is neutralized with alkali, and the strength of the wool can be partially recovered. The carbonization methods include a variety of carbonization, top carbonization, carbonization, and carbonization.
Classification

Commonly used in carded wool spinning, using a loose carbonization combined machine (see picture). The process flow is: grass-containing net hair → pickling acid → rolling acid → drying and baking → rolling carbon and carbon removal → neutralization → drying → carbonization net hair. The functions and requirements of each process are: 1 pickling acid, generally dilute sulfuric acid, there are 2 tanks, the first tank is dipping tank, soaking wool, using live water plus infiltration additives such as pulling powder, flattening, etc., making wool Uniform water absorption. The second tank is an acid pickling tank, and the acid concentration is 32 to 54.9 g/liter (3 to 5 Bé), which varies depending on the type of the net wool and the amount of impurities and the temperature of the acid solution. The acid temperature was room temperature and the pickling time was about 4 minutes. 2 Rolling the acid, the wool from the pickling tank is rolled through two pairs of rolls to remove excess acid. 3 drying and baking, is the main stage of plant carbonization, evaporation of water during the drying process, concentration of sulfuric acid, carbonization of plant material during high temperature baking. In order to protect the wool, the wool is pre-baked at a relatively low temperature, generally 65-80 ° C, and then baked at a high temperature of 102-110 ° C. At this time, the plant material is dehydrated into charcoal by sulfuric acid, and the wool damage is small. If the acid-containing wet wool is directly baked at a high temperature, the keratin of the wool is seriously damaged, and purple hair is formed, and the more the water is damaged, the greater the damage. 4 Rolling and decarbonization, the wool is passed through 12 pairs of grooved pressure rollers to pulverize the carbonized grass impurities. The speed of each pair of press rolls is gradually increased and the speeds of the upper and lower rolls are different, so the wool and grass impurities are subjected to rolling and smashing, so that the carbonized grass impurities are pulverized and eliminated by the screw removing machine. 5 Neutralization, first wash with water and neutralize the residual sulfuric acid on the wool with alkali. The neutralization process uses three tanks, the first tank is a washing tank to wash away the sulfuric acid attached to the wool, the second tank neutralizes the acid in the wool with a soda ash, and the third tank rinses the residual alkali on the wool with water. Finally, the moisture in the wool is pressed and dried, and the crucible becomes a carbonized net hair which removes grass impurities.

Tops carbonization

The principle is the same as that of loose hair, but the equipment is different. The top carbonization process is generally placed between the first needle comb and the three needle comb after combing, and also between the comb and the head comb. The carbonized tops are relatively loose due to combing or needle combing, and large impurities have been removed during combing. Therefore, low acid concentration or high acid concentration can be used for rapid impregnation, which has less damage to fibers and carbonization. thorough.

Carbonization

Used to remove vegetable impurities on the fabric, the process is the same as the bulk carbonization. Generally used for dark and thin fabrics. The carbonization can be carried out before or after dyeing. The former is called white carbonization, and the latter is called color carbonization. White carbonization requires thorough neutralization, otherwise it may cause uneven dyeing. Color carbonization should consider that the color of the dye may change under carbonization conditions, and it is preferable to use a dye that is resistant to carbonization. The carbonization equipment consists of a pickling machine and a baking machine. The fabric is flattened by a guide roller into the pickling tank, and the pickling is performed twice and the acid is pressed twice. The concentration of sulfuric acid in the pickling tank is 6-7 Bé, and the temperature is room temperature. Bake chain or tumble dryer. Neutralization of color carbonization was carried out on a rope washing machine; neutralization of white carbonization was carried out on a dyeing machine. Rinse twice with warm water before dyeing, and neutralize with ammonia. There is no separate carbon and carbon removal equipment for carbonization, which removes charcoal during dry finishing, shearing and bristles.

Broken carbonization

The vegetable fiber is removed from the shredded or shredded yarn of wool and cellulose fibers to obtain pure reusable hair. The crushed carbonization agent may be a sulfuric acid solution or a hydrochloric acid vapor. When using hydrochloric acid vapor, it is called dry carbonization. The broken car is placed in the large drum and fastened with it. The drum rotates slowly, and then the tumbling rolls in the drum. The pre-drying is carried out first, and then the high-temperature hydrochloric acid vapor is introduced for about 1.5 hours. After carbonization, hot air is blown in to remove hydrochloric acid vapor, and the machine is washed with water and dried to remove residual hydrochloric acid.
