Purpose:
As thickener, stabilizer, emulsifier, excipient, water retaining agent, film-forming agent, etc. in the production of coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics and other products.
The application in synthetic resin can make the obtained products have the characteristics of regular particles, looseness, appropriate specific gravity, excellent processing performance, etc., thus basically replacing gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the construction industry, it is mainly used in mechanized construction such as wall building, plaster finishing, caulking, etc; Especially in decorative construction, it is used for pasting ceramic tiles, marble and plastic decoration, with high pasting strength, and can also reduce the amount of cement. Used as a thickener in the coating industry, it can make the layer bright and delicate, do not remove powder, and improve the leveling performance.
Function:
It can thicken the fresh mortar to have a certain wet viscosity and prevent segregation. (thickening)
Water retention is also the most important characteristic, which helps to maintain the amount of free water in the mortar, so that the cementitious material has more time to hydrate after the mortar construction. (water retention)
It has air entrainment, which can introduce uniform and fine bubbles to improve the workability of mortar.
Performance:
1. It is easy to mix with dry powder formula.
2. It has the characteristics of cold water dispersion.
3. The solid particles are effectively suspended to make the mixture more smooth and uniform.
Mix:
1. The dry mixed formula containing cellulose ether can be easily mixed with water.
2. Get the required consistency quickly.
3. Cellulose ether dissolves more quickly and has no lumps.
be used as:
Waterproof putty for interior and exterior walls
External wall insulation mortar
Gypsum plaster and gypsum products
Cement based plastering mortar and masonry mortar
Plate joint filler
Tile adhesive
Self leveling ground material
Water based coatings and paint removers
Extruded concrete sheet
Polycarboxylic acid superplasticizer is a high-performance water reducer and a cement dispersant in the application of cement concrete. It is widely used in highway, bridge, dam, tunnel, high-rise building and other projects.
This product is green, non flammable, non explosive, and can be safely transported by train and car.
polycarboxylic acid superplasticize, because it truly designs an effective molecular structure based on the action mechanism of dispersed cement, has a super dispersive type, can prevent the loss of concrete slump without causing obvious retarding, plays a high plasticizing effect at low dosage, has good liquidity retention, the cement is adaptable to a wide range of molecular structures, has a large degree of freedom, many synthesis technologies, and has a lot of room for high-performance, and has a significant strengthening effect on concrete, It can reduce the shrinkage of concrete, and the content of harmful substances is extremely low. The technical performance characteristics give concrete excellent construction workability, good strength development, excellent durability. polycarboxylic acid superplasticize has good comprehensive technical performance advantages and environmental protection characteristics, which meets the needs of modern concrete engineering. Therefore, polycarboxylic acid superplasticize is gradually becoming the preferred admixture for preparing high-performance concrete.
1. It has good compatibility with all kinds of cement, good slump retention performance of concrete, and prolongs the construction time of concrete.
2. Low dosage, high water reduction rate and small shrinkage.
3. Greatly improve the early and late strength of concrete.
4. This product has low chloride ion content and low alkali content, which is conducive to the durability of concrete.
5. The production process of this product is pollution-free, formaldehyde free, in line with ISO14000 international standards for environmental protection management, is a green environmental protection product.
The redispersible polymer powder product is white or off white flowable powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid.
Purpose:
ceramic tile adhesive
bonding mortar of external wall external insulation system
external wall external insulation system plastering mortar
tile jointing agent
self flowing cement mortar
flexible putty for inner and outer walls
flexible crack resistant mortar
Polypropylene short fiber is a kind of strong bundle monofilament fiber made from polypropylene with a unique production process. Adding it into concrete mortar can effectively control the micro-cracks caused by solid plastic shrinkage, dry shrinkage, temperature change and other factors of concrete mortar, prevent and slow the formation and development of cracks, and greatly improve the crack resistance, impermeability, impact resistance and seismic resistance of concrete It can be widely used in various mortars, underground waterproof works, walls, floors, cement, basements, roads and bridges. Performance of polypropylene in dry powder mortar or concrete 1. It is evenly dispersed in the mortar to form a three-dimensional disordered structure inside, and can lock the moisture inside the mortar, with strong grip and wrapping force; 2. It is not easy to agglomerate in mortar or concrete, which effectively ensures the play of its crack prevention performance. It is convenient to use, without changing the mortar ratio. Put the fiber into the mortar mixture and add water to mix evenly; 3. In the concrete, the wear resistance, impermeability, freeze-thaw resistance of the concrete are improved, and the reinforcement protection function is enhanced; 4. The fiber has stable chemical properties, strong acid and alkali resistance, and can be used in any project.
Fiber type: bundle monofilament density: 0.91/g/cm3 equivalent diameter: 18~48 tensile strength: â?¥ 500MPa modulus of elasticity: â?¥ 3850mpa elongation at break: 10-28% acid and alkali resistance: very high melting point: 160~180 â?? ignition point: 580 length: 3, 6, 9, 12, 5, 54mm advantages of short fibers in mortar improve the impermeability of mortar improve the toughness of cement mortar, Relieve fatigue and abrasion resistance improve crack resistance improve the durability of cement mortar improve the resistance of cement mortar to freeze-thaw damage
