Specification
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;
>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: Is the catalyst used in the starch phosphate reaction
- (Cat1, cat2, cat4 and cat5) in the presence of terephthalic acid,
- Q: how could scientists know the exact catalyst for every reactions??? THANX sooo much
- Believe me, nema, there's no way that we chemists know the best catalyst for every reaction. That would be simply impossible. However, from the type of reaction, the reactants, products, reaction conditions, solvents, etc. and from one's experience and the literature (papers and patents) one can get a good idea for most reactions of the type of catalyst that has worked for similar systems. One then starts off with a catalyst from the literature and modifies or changes it if improvement is needed based on chemical principles that one learns. There are also some theoretical calculations that can be made. Sometimes they work and sometimes they don't :) If it is an industrially important process like the Haber process for making ammonia from nitrogen gas and hydrogen gas, there may be thousands of catalysts which have been tried and evaluated. New minor improvements are being made every day. When a company does find a very good catalyst for an important reaction, often they keep it a trade secret. The good catalyst can make a huge difference in how commercially successful a particular process is. That's a large part of what chemical engineers do. You may never know if you have the best catalyst. The most you can hope for is one that is good enough. So it's a few parts personal knowledge, a few parts literature, a couple of parts theory, a lot of experimentation and often, more than not, a little luck. :)
- Q: Is the catalyst in the field of inorganic chemistry?
- The catalyst is a branch of physical chemistry
- Q: It is best to tell me what the role of sulfuric acid in these reactions, respectively
- Esterification reaction (dehydration), nitration (dehydration, concentrated nitric acid), carbonation reaction or dehydration reaction (organic matter in sulfuric acid blackening, dehydrating agent), sulfonation reaction (dehydrating agent), ethylene (dehydrating agent).
- Q: To write a 1500 words of small papers, so please help you busy
- Want to write a good article do not reach out.
- Q: What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
- Hundreds of years ago the news once the industrial production and emissions of ozone generated less way, the ozone layer will still be thin.
- Q: Effect of Catalyst on Chemical Reaction Rate
- The catalyst can only change the rate of chemical change (faster or slower), does not change its own quality and chemical properties, nor does it change the amount of reaction product.
- Q: A substance involved in chemical reflection, but reflects the quality of the material before and after the change, you say it is a catalyst?
- Is a catalyst. The catalyst is actually involved in the reaction, (these are multi-step reaction), but in the final time from the reaction out.
- Q: Explain how catalysts help to reduce costs in industrial processes !?Thanks
- they reduce the activation energy of a specific chemical reaction, which in turn reduces the temperature at which a reaction will occur at any significant rate (and therefore fuel costs) while generally making the reaction occur faster. In general, if you can catalyze a reaction, you can get away with using less robust equipment because you don't need as much energy.
- Q: I know that a species that does not appear in the chemical equation may also affect the rate of a reaction - e.g. a catalyst. But does that mean the catalyst can be present in the rate equation, and if so are catalysts always present in the rate equation?
- Yes, a catalyst can be included in a rate law. That's because, most reactions occur in a series of step and the rate is based on the rate determining step, which is the slowest step. A catalyst may be a reactant in the rate determining step, and a product in a subsequent step. Therefore, the catalyst is not included in the overall reaction. But a catalyst need not always be in the rate law. The rate law is usually based on the rate determining step. ========== Follow up =========== In the free response questions on the AP chemistry exam there has been at least one case where a rate law included a catalyst( 2002D). Brown and LeMay always include at least one in their examples, and I always cover this situation when I teach rate laws and mechanisms in AP chemistry. Here is one comment: Other examples of species not in the balanced reaction occurring in the rate law would include catalysis, where a catalyst does not normally appear in the balanced reaction but does appear in the rate law. www.chem.arizona.edu/~salzmanr/48... Consider this generalized reaction which is catalyzed by M A + B --C A + M --Q ... slow Q + B --C ... fast M is the catalyst, and Q is the intermediate. The slow, or rate determining step, depends only on the concentrations of A and M, the catalyst. So even though the overall reaction does not include, M, the rate law does. Rate = k[A][M]
