Product Description:

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.

Application in Building:

External wall insulation system (EIFS)

>Bond strength: HPMC can provide the greatest degree of high adhesive bond strength of mortar.
>Performance: The mortar added HPMC has the right consistency, non-sagging. When using, the mortar is easy to work continuously, uninterrupted.
>Water retention: HPMC can wet the wall insulation easily, easy to paste, and also make other additional materials reach the best affects.

>Absorbent: HPMC can minimize the air-entraining volume, lower water absorption of mortar.
>Recommended brand: 75CMAX75000(S), 75CMAX100000(S), 75CMAX200000(S) 

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:can you guys help me by listing all the catalysts?
copper nickel zinc common catalysts are solid acids such as the silicas, alumina, and zeolites it depends on the reaction
Q:catalyst question?
The purpose of a catalyst is to provide an alternate pathway for a reaction to proceed, often one with a lower activation energy, such that the reaction will generally proceed faster. The key to catalysts if they they are NOT consumed by the reaction in the end (they may be consumed in an intermediary step, but if so, a subsequent step will recreate the catalyst). In other words, catalysts do not actually participate in the reaction, so they may be reused when the reaction has completed.
Q:Why does the chemical and chemical properties change before and after the reaction?
Catalysts are homogeneous catalysts with heterogeneous catalysts. The heterogeneous catalyst exhibits a reaction in a different phase (e.g., a solid catalyst in a liquid mixing reaction) and a homogeneous catalyst is a reaction in the same phase (for example, a liquid catalyst in a liquid mixing reaction). A simple heterogeneous catalytic reaction involves the addition of a reactant (or en-ch: substrate; zh-tw: subject) adsorbed on the surface of the catalyst, and the bond within the reactant causes a new bond due to the fragility of the bond, But because of the product and the catalyst between
Q:what is a catalyst ?
catalyst is a substance that can cause a change in the rate of a chemical reaction without itself being consumed in the reaction; the changing of the reaction rate by use of a catalyst is called catalysis. Substances that increase the rate of reaction are called positive catalysts or, simply, catalysts, while substances that decrease the rate of reaction are called negative catalysts or inhibitors.
Q:What does what does catalyst mean?
the compound that allows for a chemical reaction. and example would be The enzyme catalase is the catalyst that allows hydrogen peroxide to break down into water
Q:how heterogeneous catalyst work?
The Reduction Catalyst The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example: 2NO =N2 + O2 or 2NO2 =N2 + 2O2 The Oxidization Catalyst The oxidation catalyst is the second stage of the catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning (oxidizing) them over a platinum and palladium catalyst. This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. For example: 2CO + O2 =2CO2
Q:Please name 2 common examples of catalysts.Thank you?
Common Catalysts
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 reaction, the rate of decomposition reaction is related to the quality of the catalyst?
There are relationships
Q:Chemical catalyst in several ways
Two, can speed up and slow down
