Building Construction Hydroxypropyl Methyl Cellulose (HPMC)
Brief introduction:
Hydroxypropyl Methyl Cellulose (HPMC) helps building materials apply more easily and perform better. They provide water retention and cohesiveness to mixtures. With special modification, it can be used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product.
It is widely used as thickener, adhesive, water preserving agent, film-foaming agent in building materials, industrial coatings, synthetic resin, ceramic industry, medicine, food, textile, agricultural, cosmetic and other industries.

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;

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.

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.

- Q: describe a biological catalyst?
- One of the best known biological catalyst reactions is the Fixation of Nitrogen. Biological Nitrogen Fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by a bacterial enzyme called nitrogenase. Microorganisms that fix nitrogen are called diazotrophs. The formula for BNF is: N2 + 8H+ + 8e? + 16 ATP → 2NH3 + H2 + 16ADP + 16 Pi Although ammonia (NH3) is the direct product of this reaction, it is quickly ionized to ammonium (NH4+). In free-living diazotrophs, the nitrogenase-generated ammonium is assimilated into glutamate through the glutamine synthetase/glutamate synthase pathway.
- Q: pls give one or two catalysts that are used in the industry for example:Rhodium catalyst in a catalytic converter of a car or the Iron catalyst for making ammoniaTHANKS :)
- i will tell you the hydrogen and carbonmonixide production in indsutry they will use alumina based nickel catalyst for adsorption of gases, at high temperature it will breaks as small molecules like hydrogen, co2, co,ch4, after they will separate them using carbon molecular seives as catalyst. another catalyst for hydrogenation of double bond is copper chromate for sulphur removal from disel and petrol they will use COMOX ( copper and molybdinum catalyst ) after then pass through zinc sulfide with hydrogen gas , the sulfur will removed as a hydrogen sulfide.
- Q: Explain how a catalyst may increase the rate of chemical reaction?
- A catalyst lowers the activation energy of a reaction without affecting the reaction in any way.
- Q: To write a 1500 words of small papers, so please help you busy
- Change the course of the reaction
- Q: What are the properties of the catalyst (eg, specificity)?
- The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is as highly selective (or specific) as the relationship between the lock and the key. A catalyst is not for all Chemical reactions are catalyzed, for example, manganese dioxide in the thermal decomposition of potassium chlorate in the catalytic role to speed up the chemical reaction rate, but other chemical reactions do not necessarily have a catalytic effect.Some chemical reaction is not only a single catalyst, such as potassium chlorate Thermal decomposition can play a catalytic role in the magnesium oxide, iron oxide and copper oxide and so on.
- Q: In chemistry what is a catalyst and an example?
- Catalysts are substances that increase the rate of a reaction by providing a low energy shortcut from reactants to products. In some cases, reactions occur so slowly that without a catalyst, they are of little value. Nearly all reactions that occur in living cells require catalysts called enzymes- without them, life would be impossible. There are two important classes of catalysts: homogenous catalysts like enzymes and aqueous ions that are uniformly mixed with the reactants, and heterogeneous catalysts that provide a surface that holds and reconfigures the reactants in a way that is favorable for reaction. Examples of homogeneous catalysis. Catalysts in solution with the reactants usually provide fast reaction paths by allowing reactants to form an unstable intermediate that quickly decomposes into products. For example, the substitution reaction CH3CH2OH(g) + HCl(g) H2SO4 ----->CH3CH2Cl + H2O(ell) is catalyzed by acid because the ethanol is converted into unstable CH3CH2OH2+, which quickly reacts with Cl- to produce the products. Definition: A catalyst is a subtance that increases the rate of a chemical reaction by reducing the activation energy, but which is left unchanged by the reaction. Examples: A piece of platinum foil is a catalyst for the combustion of methane in air.
- Q: Can chemical reaction limits be changed by catalyst or other methods?
- No, the catalyst can only speed up the chemical reaction, but can not change the chemical limit.
- Q: Which chemical reaction is added to the catalyst in order to slow down the reaction
- CaC2 and water reaction to ethylene plus salt water (slow chemical reaction rate)
- Q: Is there a catalyst in the chemical shop?
- If it is like vanadium pentoxide, which catalyzes sulfur dioxide, do not sell it because vanadium is highly toxic and most of the catalyst is expensive
- Q: An important property of the catalyst is that the reaction equilibrium is not changed while increasing the forward reaction rate and the reverse reaction rate. However, because the enzyme for the specificity of the substrate, is not almost every reaction by the enzyme are one way to do it.
- Only answer lz, the last question and. The reason is that both the restriction endonuclease and the ligase are required for certain reaction conditions and the reaction substrate. And the reaction conditions are different, so that the final results are different, of course, the enzyme is relatively speaking is not so high, perhaps the destruction is always stronger than the building it. The ligase is the need for a specific substrate, three distilled water, temperature, time (long time do not forget the formula) to control, it may have a certain proportion of connection. So this is two questions.
