Why can the quality of China High water retention HPMC manufacturers be tested under high temperature?

Because the water retention of methyl cellulose ether under high temperature conditions is an important indicator to distinguish the quality of methyl cellulose ether. Only excellent China High water retention HPMC manufacturers products can effectively solve the problem of water retention at high temperatures. In high temperature seasons, especially in hot and dry areas and thin-layer construction on the sunny side, high-quality China High water retention HPMC manufacturers is required to improve the water retention of the slurry.

1) High-quality China High water retention HPMC manufacturers has very good uniformity. Its methoxy and hydroxypropoxy groups are evenly distributed along the cellulose molecular chain, which can improve the association of oxygen atoms on hydroxyl and ether bonds with water The ability to form hydrogen bonds turns free water into bound water, thereby effectively controlling the evaporation of water caused by high temperature weather and achieving high water retention.

2) High-quality China High water retention HPMC manufacturers can be uniformly and effectively dispersed in cement mortar and gypsum-based products, and wrap all solid particles, and form a layer of wetting film. The water in the base is gradually released over a long period of time. The hydration reaction occurs with the inorganic cementitious material to ensure the bonding strength and compressive strength of the material.

Therefore, in the high temperature summer construction, in order to achieve the water retention effect, it is necessary to add high-quality China High water retention HPMC manufacturers products in sufficient quantities according to the formula. Otherwise, insufficient hydration, reduced strength, cracking, hollowing and hollowing will occur due to excessive drying. Quality problems such as falling off also increase the difficulty of construction for workers.

The High water retention HPMC produced by Milestone Industrial Co. Ltd. has stable water retention and thickening performance, and can exhibit excellent water retention performance when working in summer or high temperature.
