【Mortar Vision】Multiple applications of construction grade cellulose ether

Tile, as a functional decorative material, has been widely used around the world, and how to paste this durable material well and make it safe and durable has also been a concern for people.

I. Cellulose ether products applied to tile adhesive.

        The emergence of tile adhesive, to a certain extent, to ensure the reliability of tile adhesive. Different construction habits and work methods, different construction performance requirements for ceramic tile adhesive. In the current domestic ceramic tile adhesive construction, thick paste mode (traditional adhesive backing) is still the mainstream construction method, when using this method, the requirements of the tile binder: easy to mix; easy to apply glue, non-stick knife; good adhesion; good anti-slip. With the development of ceramic tile binder technology and construction process improvement, troweling method (thin paste method) has also been gradually adopted, the use of this         construction method, the requirements of the ceramic tile binder; easy to mix; spreading should be good, non-stick knife; anti-slip performance should be good; good wetting of the tiles, there is a long open time. Usually, the selection of different types of cellulose ether can make the tile binder to achieve the corresponding ease of use, constructability.

II. Cellulose ethers applied to thermal insulation systems

        Cellulose ether is one of the main additives of thermal insulation mortar, although the addition amount is very low, but it can significantly improve the performance of the mortar, it can improve the consistency of the mortar, working performance, bonding properties and water retention properties, etc., in the field of thermal insulation mortar has a very important role.

III. Cellulose ether applied to putty

        In the aesthetic view of most people, the smoothness and flatness of a building's surface is usually considered beautiful. The application of putty thus came into being. Putty is a thin-layer plastering material that plays an important role in both the decorative and functional aspects of a building. Decorative coating of the three levels: grass-roots wall, putty leveling layer, finish layer, the main role of different, their respective modulus of elasticity, deformation coefficient is also different, when the ambient temperature, humidity and other changes, the deformation of the three layers of materials are also different, which requires the putty and finish layer materials to have the appropriate modulus of elasticity, relying on its own elasticity, flexibility to eliminate the concentration of stress, thus playing resistance to the grass-roots level of cracking, Prevent the finish layer from peeling. A good performance putty, should have good wetting properties of the substrate, can be recoated performance, smooth scraping, enough operating time and other construction properties, should also have excellent bonding properties, flexibility, sandability and durability.

IV. Cellulose ethers applied to common mortar

        The use of ready-mixed mortar is an effective means to improve project quality and civilized construction level; the promotion and application of ready-mixed mortar is conducive to the comprehensive utilization of resources, which is an important measure for sustainable development and the development of recycling economy; the use of ready-mixed mortar can greatly reduce the rate of secondary reworking of building construction, improve the degree of mechanization of construction, improve the efficiency of construction, reduce the intensity of labor, and improve the comfort of the living environment, and reduce the total amount of building energy consumption. At the same time, it can reduce the total building energy consumption. In the process of commercialization of premixed mortar, cellulose ether plays a milestone role. The reasonable application of cellulose ether makes the mechanized construction of ready-mixed mortar possible; good performance of cellulose ether can significantly improve the construction performance of mortar, pumping and spraying performance; its thickening ability can improve the wetting ability of wet mortar on the grass-roots wall, so as to improve the bond strength of the mortar; it can adjust the opening time of the mortar; the incomparable water retention ability can greatly reduce the plastic cracking of the mortar. Chances of plastic cracking of mortar can be greatly reduced; the hydration of cement can be made more complete, thus improving the overall structural strength. Take ordinary plastering mortar as an example, as a good mortar, mortar mix should have good construction performance: easy to mix, good wetting of the grass-roots wall, smooth application without sticking to the knife, enough operating time (small loss of consistency), easy to leveling; mortar hardening body should have excellent strength properties and surface appearance: suitable compressive strength, bonding strength to the grass-roots wall, good durability, surface leveling, No drum, no cracking, no powder.

V. Cellulose ether applied to decorative mortar

        Caulk as an important part of the tile tiling project, not only to improve the overall effect of the tile finishing project and the contrast effect, but also play an important role in improving the waterproof seepage resistance of the wall. A good tile adhesive products, in addition to rich colors, uniform color, but also should have easy to operate, fast on the strength, low shrinkage, low porosity, waterproof seepage and other functions. Cellulose ether in the caulking products to provide excellent operational performance can also reduce the rate of wet shrinkage, and lead to a small amount of gas, team cement hydration effect is small. Decorative mortar is a new type of wall finishing material that integrates decoration and protection. Compared with natural stone, tile, paint and glass curtain wall and other traditional wall decorative materials, it has unique advantages. Compared with paint: high grade; long service life, the service life of decorative mortar is several times of the paint, or even dozens of times, and the same life as the building. Compared with tiles and natural stone: similar decorative effect; lighter building load; safer. Compared with glass curtain wall: no reflection; safer. A good performance of decorative mortar products should have: excellent operational performance; safe and reliable bonding; good cohesion.

VI. Cellulose ether applied to self-leveling mortar

        The role that cellulose ether for self-leveling mortar should achieve:

※Ensure the flowability of self-leveling mortar

※Improve the self-healing ability of self-leveling mortar.

※Help to form a smooth surface

※Reduce shrinkage and increase bearing capacity

※Improve the adhesion and cohesion of self-leveling mortar to the substrate.

VII. Cellulose ether applied to gypsum mortar

        Cellulose ethers play an important role in gypsum-based products, whether they are whitewash plaster, inlay, putty, or gypsum-based self-leveling and gypsum-based thermal insulation mortar.

Suitable cellulose ether varieties are not sensitive to the alkalinity of gypsum; can be quickly infiltrated in gypsum products without agglomeration; have no negative effect on the porosity of cured gypsum products, 

thus ensuring the respiratory function of gypsum products; have a certain retardation effect but do not affect the generation of gypsum crystals; provide suitable wet adhesion for the mix to ensure the bonding ability

of the material to the substrate; substantially improve the gypsum performance of gypsum products It can improve the gypsum performance of gypsum products greatly and make them easy to spread without sticking to tools.
