Hydroxypropyl methylcellulose (HPMC) for granite machine-made sand is a special-purpose polymer material used to improve the physical properties and construction performance of granite machine-made sand. HPMC mainly plays the role of thickening, water retention, bonding and stabilization in granite machine-made sand, so as to improve the viscosity, fluidity and water retention of mortar, and reduce the difficulty of construction.
In the production and use of granite machine-made sand, due to the coarse sand grains and low moisture content, it is easy to produce problems such as segregation, water leakage and difficult construction. By adding a certain amount of hydroxypropyl methylcellulose, these undesirable phenomena can be effectively improved, making the mortar easier to pave, compact, and trowel, while improving its anti-segregation and anti-cracking properties to obtain better construction quality.
It should be noted that when using hydroxypropyl methylcellulose for granite machine-made sand, the addition amount should be strictly controlled and fully stirred to ensure its effect. At the same time, it is also necessary to pay attention to compatibility and compatibility with other materials to avoid adverse reactions or reduce the effect.
There is no unified standard for hydroxypropyl methylcellulose (HPMC) indicators for granite manufactured sand. However, in general, the type indicators of hydroxypropyl methylcellulose such as methoxy content, hydroxypropyl content, gel temperature, loss on drying and pH value may have an impact on the performance of granite manufactured sand.
Specifically, the methoxy content and hydroxypropyl content of hydroxypropyl methylcellulose affect its water solubility and viscosity, the gel temperature affects its thickening effect and stability, and the loss on drying and pH value may affect its water retention and stability.
In practical application, it is necessary to select the appropriate hydroxypropyl methyl cellulose type and addition amount according to the specific performance requirements and construction conditions of granite machine-made sand to achieve the best construction effect and economic benefits.
