CMC Ceramic Grade Carboxymethyl cellulose

Description:

CMC for ceramics features uniform distribution of substituents (carboxymethyl group) on the cellulose backbone. It produces fewer gel granules in glaze formulation.

Application Field:

1. It contains no colored impurity and is 100% combustible under firing condition, to ensure clean ceramic glaze.
2. It can stabilize physical and chemical property of glaze formulation.
3. It can improve glaze adhesion and reduce glaze cracking.
4. It facilitates formation of a smooth dense glaze layer.
5. It can improve the rheological property of glaze formulation.
6. The glaze viscosity is proportional to the concentration of CMC added

CMC Ceramic Grade Carboxymethyl cellulose

Package and Storage:

1. The solid product can be packed in inner plastic bags, and further in polypropylene woven bags with each bag containing 25Kg.

2. The solid product should be prevented from scattering on the ground because the hygroscopic powder can cause slipperiness.

Q: On the issue of chemical balance and catalyst: The catalyst can only improve the equilibrium speed, reducing the time to reach equilibrium, but will not affect the chemical balance.

Q: In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction: Half is not easy to save trouble

Q: The "one-to-two change" of the catalyst is that the quality and chemical properties of the reactants are constant or the quality and chemical properties of the catalyst are constant?: The change in chemical reaction rate is the same as the chemical nature and quality

Q: What is a catalyst in a chemical reaction?: A catalyst provides an alternative reaction pathway with a lower activation energy. So it speeds up the rate of reaciton because the energy of the particles/reactants doesnt have to be that high to OVERCOME the activation energy so it can therefore react. The activation energy is the minimum amount of energy required for particles to react, so the lower it is, the more faster a rate of reaction will be.

Q: What are the characteristics of the catalyst in the chemical reaction?: In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.

Q: Could you please explain it, i know they increase reaction rates but how?: A catalyst lowers the activation energy (the minimum amount of energy needed for a reaction to take place). This means that the particles can react with less energy than they needed before the catalyst was added. (Think about it: if the government lowered the legal age to buy cigarettes, then more people could legally buy cigarettes. Similarly, if we lower the amount of energy needed for particles to react, then more particles can react). Also, a catalyst provides a surface on which the reaction can take place. This increases the number of collisions between the particles of the substances that are reacting.

Q: The future direction of employment how, in what kind of units to do what work, how the closure rate? The: Generally in the chemical plant to do engineering design engineers, the past few years, science and engineering graduates generally do not worry about work.

Q: The greater the chemical adsorption strength, the catalyst activity changes: If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.
