For the external wall insulation system, it generally includes the bonding mortar of the insulation board and the plastering mortar that protects the surface of the insulation board. A good bonding mortar needs to be easy to stir, easy to operate, non-stick to the knife, and has good anti-sag. effect, good initial adhesion and so on.
The bonding and plastering mortar requires cellulose to have the following characteristics: good encapsulation and workability for fillers; a certain air entrainment rate, which can increase the output rate of the mortar; long operating time; good anti-sag effect And the wetting ability for different base surfaces; the slurry stability is good, and the consistency of the mixed slurry is maintained for a long time. Shandong “Chuangyao” brand hydroxypropyl methylcellulose can meet the basic needs of bonding and plastering mortar applications.
Hydroxypropyl methylcellulose has high water retention performance in the field of bonding and plastering mortar. High water retention can fully hydrate the cement, significantly increase the bonding strength, and at the same time, it can appropriately improve the tensile strength and shear strength. Greatly improve the construction effect and improve work efficiency.
Hydroxypropyl methylcellulose plays a key role in bonding and increasing strength in thermal insulation mortar materials, making mortar easier to coat, improving work efficiency, and more resistant to sag. Working time, improve shrinkage and crack resistance, improve surface quality, improve bond strength.
In water or other homogeneous liquid medium, hydroxypropyl methylcellulose can be dispersed into fine particles, suspended in the dispersion medium and dissolved, without causing precipitation and agglomeration, and has protective colloid and stabilizing effects. Yao company can adjust the production process and control the viscosity time according to customer needs.
