It is summarized that hypromellose ether has many properties, such as thickening, water retention, reinforcement, crack resistance, abrasion resistance, etc. .
It can improve various physical and chemical properties of mortar and improve durability of mortar. Performance
1. The hypromellose is widely used in all kinds of mortars including masonry mortars, plastering mortars and leveling mortars to improve the bleeding of mortars.
2. The hypromellose ether has the thickening effect, improves the construction performance and workability of the mortar, and improves the saturation and volume of the mortar.
3. The hypromellose can improve the cohesiveness and operability of mortar, and overcome the common defects of common mortar such as shell forming and hollowing. Four. The hypromellose has a retarding effect, which can ensure the time of the mortar and improve the construction effect of the mortar.
Hypromellose can introduce appropriate amount of bubbles, can greatly increase the frost resistance of mortar, mortar durability. Hypromellose ether is a combination of physical and chemical effects to play a role in water retention and thickening, in the hydration process can produce a cause of micro-expansion of the material, thus mortar has a certain degree of micro-expansion, the cracking caused by shrinkage of mortar in later hydration process is prevented, and the service life of the building is increased.
Use Method 1. The recommended mortar ratio of M10 plastering mortar is: cement: fly ash: Sand = 120:80:800(if fly ash is not used, the amount of fly ash is replaced by cement) . The content of cellulose ether is 0.5 ~ 1.0% of the total mortar. 2. According to the measured good cement and sand, and then add cellulose ether prepared mortar, in the construction site according to the prescribed amount of water mixing water use. 3. The mixing method of mortar: first of all, the measured water into the container, and then the mortar into the container for mixing. Four. The mortar mixed with cellulose ether of mortar is mixed mechanically. The mixing time starts from 3-5 minutes after the material is put into the mortar. 5. Mortar should be mixed with the use, usually should be finished within 4 hours after mixing, when the temperature during construction more than 30 ° C, must be used within 3 hours after mixing.
