Interior and exterior wall interface agent

>Easy to mix, without of agglomeration: HPMC can significantly reduce the friction in the dry powder during the process of mixing with water, which makes it easy to mix and save the blending time.

>Water retention: HPMC can significantly reduce the moisture absorption by the wall. Good water retention can ensure the cement compound with a longer time, also can ensure that workers are able to carry out many times of scraping for the putty on the wall.
>Good working performance stability: even in high temperature environment, HPMC can still maintain good water retention. it is suitable for construction in the summer or hot areas.
>Increased water demand: HPMC can significantly improve the water demand of the putty materials. On the one hand, it improves the operational time after putty put on the wall, on the other hand, it can increase the coating are of the putty, which can make the formula more economical.

>Recommended brand: 75CMAX60000(S), 75CMAX75000(S)

Tile adhesive

>Water retention: HPMC can reduce the moisture absorbed by the substrate and the tile, retain the moisture in the adhesives as much as possible, making mortar still have adhesion after coating for a long time. Significantly extend open time and makes bigger coating area for the worker each time, and improve the efficiency.
>Improve bond strength, improve anti-slip performance: HPMC ensure non sagging of the tiles during working, especially for heavy tile, marble and other stone materials.
>Work performance: The lubricity of HPMC can increase the workability of the mortar significantly, which makes the mortar easy to coating and improve efficiency.
>Improve mortar wetting property: HPMC give mortar consistency, enhance the wetting ability of mortar and substrate, increase the binding strength of wet mortar, especially for the recipe with high water cement ration;
>Recommended brand: 75CMAX40000(S), 75CMAX75000(S), 75CMAX100000(S)

Crack Filler

>Workability: provide the right viscosity, plasticity, and easy to work;
>Water retention: can make the slurry fully hydrated, extending the working time and avoid cracking.

>Anti-hanging: HPMC can make a strong adhesion on the surface for the slurry and not sag;

>Recommended brand: 75CMAX40000(S), 75CMAX75000(S), 75CMAX100000(S)

Self-leveling mortar

>Prevent bleeding: HPMC can play a very good role to prevent the slurry sedimentation, bleeding.
>Maintain liquidity, and improve retention: low viscosity HPMC will not affect the slurry flow effect and easy to work. While possesses certain water retention, makes the good surface effect after self-levelling and avoid cracks.

>Recommended brand: 75CMAX400~600

Gypsum-based plaster

>Water retention: HPMC can retain moisture in the mortar, thus make gypsum completely solid. The higher the viscosity is, the stronger the water-retention capacity, vice versa..
>Sag resistance: allow the worker make the thick coating without causing ripple building.
>Mortar yield: For fixed weight of dry mortar, the exist of HPMC can provide more wet mortar.
>Recommended brand: 75CMAX75000(S), 75CMAX100000(S)

Q:The best use of chemical catalysts
Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst
Q:What is the nature of the catalyst before and after the chemical reaction?
Chemical properties do not change better. Some properties of the catalyst may change before and after the reaction. If the experiment proves, the state of the catalyst before and after the reaction changes, and some changes from powder to powder.
Q:High chemistry: Does the catalyst affect the heat and heat of the reaction?
Q:Can a catalyst react with a reactant?
it can react to start the reaction but should be regenerated during the reaction. if it reacts and not regenerated,then its better to call it reactant instead of catalyst
Q:What is the principle of catalyst reaction rate in chemical reactions?
Can significantly change the reaction rate and its own chemical properties and quantity in the reaction before and after the basic material unchanged. The catalyst has a positive catalyst (i.e., accelerates the reaction rate) and a negative catalyst (i.e., reduces the reaction rate), and generally does not specifically refer to both the positive catalyst.
Q:Biology Question - Catalysts?
Organic or Inorganic - the catalyst (enzyme) must be organic to be found in the cell. Catalysts speed up chemical reactions inside a cell and must therefore be organic to be a functioning part of the cell. Reusable - There are so many reactions that catalysts are involved in that it would be a waste for the cell if a catalyst could only last one reaction, especially if there are inhibitors and competition for the active site. Catalysts must be reusable in order to keep the cell functioning. Catalysts always remain unchanged after a reaction. HIihly Specific - Catalysts are only made to catalyze one specific chemical reaction. Their active site has proteins bonded in such a way that only certain elements can enter the active site and H bond with those proteins. The fact that they are highly specific maximizes the productiveness of the cell. And it ensures that the cell only has catalysts to reactions that it needs to be completed. It also ensures that the elements are correctly bonded with eachother. If any two elements could enter the active site, there is no guarantee that the correct product will be produced. Catalysts and Enzymes must be super highly specific in order to properly function. Lowers Activation Energy - The more energy a cell has to spend to catalye a reaction, the worse it is for the cell and the less ATP is has for other reactions. Catalyts hold the substrates together so there is less energy that is needed to have the two substrates react with eachother. Activation Energy is the energy that is needed to start a reaction. So the less energy used by the cell for reactions, the better for the cell. Hope this helps
Q:Chemical master invited (about catalyst)
From the thermodynamics can be reaction, and the three formulas can be added to eliminate the intermediate product, indicating that the reaction may occur. The definition of the catalyst is not complete. I am a junior undergraduate student of Jilin University School of Chemistry, according to the definition of the catalyst in the university textbook, the catalyst itself reacts with the reactants to produce unstable intermediates. After the reaction is finished, the intermediate product is explained and the catalyst is reduced. Apparently did not participate in the reaction. So the catalyst to change the course of the reaction, the original reactants to go through a relatively high energy to produce products, there will be a catalyst after a few relatively low energy barrier, so much easier, the reaction rate is greatly accelerated The It can be seen, the catalyst is not no response, but only after the completion of the reaction to restore it. It can also be seen that the amount of catalyst does not matter, and some reactions require the amount of catalyst to be approximately equal to the amount of reactants. Waiting for you to high school and university to further study on this issue will have a more clear understanding of the.
Q:Why can some catalysts be reused in (chemistry)?
Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.
Q:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent
Activated molecular map
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.
