The thickening effect of cellulose ether depends on: the degree of polymerization of cellulose ether, solution concentration, shear rate, temperature and other conditions. The gelling property of the solution is unique to alkyl cellulose and its modified derivatives. The gelation properties are related to the degree of substitution, solution concentration and additives. For hydroxyalkyl modified
The difference between putty and paint is: different concepts, different ingredients, different performance, different processing steps, and different usage methods. The concept is different: Paint is applied to the surface of the object to be protected or decorated to form a continuous film firmly attached to the object to be coated. Putty is a decorative
In the use of mortar, the consistency and anti-sag performance of mortar are very important indicators. Mortar must be easy to apply while having the proper consistency and not sag when thick mortar is applied. Tile adhesives need the same properties so that they can help support heavy bricks perpendicular to the wall. Cellulose ether
What is the difference between pure HPMC and adulterated? The Pure hydroxypropyl methylcellulose is visually fluffy and has a small bulk density, ranging from 0.3--0.4/ml. The adulterated HPMC has better fluidity and a heavier feel, which is obviously different from the appearance. Pure hydroxypropyl methylcellulose aqueous solution is clear, with high light transmittance and water
The role of cellulose ether in cement mortar (1) The role of cellulose ether in cement mortar (2) Cellulose ether - air-entraining effect Cellulose ether has obvious air-entraining effect on fresh cement-based materials. Cellulose ether has both hydrophilic groups (hydroxyl groups, ether groups) and hydrophobic groups (methyl groups, glucose rings). And it is a surfactant
The role of cellulose ether in cement mortar (1) Cellulose ether - thickening and thixotropy Cellulose ether gives wet mortar excellent viscosity. Can significantly increase the bonding ability of wet mortar and base. Improve the anti-sag performance of mortar. It is widely used in plastering mortar, brick bonding mortar and external wall insulation system. The
In ready-mixed mortar, as little as cellulose ether can significantly improve the performance of wet mortar. It can be seen that cellulose ether is a major additive that affects the construction performance of mortar. Choose different varieties, different viscosities, and different particle sizes. Different degrees of viscosity and addition of cellulose ether also have different
Factors Affecting Mortar Strength 1. Mixing ratio: The mix ratio mainly refers to the proportion combination of various raw materials in the mortar, which is generally provided by the laboratory. The mixing ratio should be measured strictly, requiring each material to be weighed before entering the mixer. The error required for material measurement is: cement
Hydroxyethyl cellulose to make water-based paint (1) Because the surface-treated hydroxyethyl cellulose is powdery or fibrous solid. When preparing hydroxyethyl cellulose mother liquor, remind you to pay attention to the following points: (1) Before and after adding hydroxyethyl cellulose, keep stirring until the solution is completely transparent and clear. (2) Slowly sieve into the mixing
HEC(Hydroxyethyl cellulose) is used as an additive in various aspects. This article briefly introduces the main characteristics of HEC. Thickening Hydroxyethyl cellulose (HEC) is an ideal thickener for paints and cosmetics. In practical application, the combination of its thickening property, suspending property, safety, dispersibility and water retention will produce more ideal effect. Pseudoplasticity Pseudoplasticity is
