Kima Gypsum Hydroxypropyl Methyl Cellulose Product Features

01. Product features of Kima gypsum-based hydroxypropyl methylcellulose:

1. Improve the spreading rate of gypsum base: Compared with similar hydroxypropyl methylcellulose ether, the spreading rate is significantly increased.

2. Application fields and dosage: light bottom plastering gypsum, the recommended dosage is 2.5-3.5 kg/ton.

3. Excellent anti-sag performance: it will not sag when it is hung in a single layer when it is hung in a thick layer, and it will not sag when it is hung in more than two layers (above 3cm), and it has excellent plasticity.

4. Excellent constructability: easy and smooth when hanging, can be molded at one time, and has plasticity.

5. Excellent water retention rate: prolong the operation time of gypsum base, improve the weather resistance of gypsum base, increase the bonding strength between gypsum base and the base layer, excellent wet bonding performance, and reduce landing ash.

6. Strong compatibility: It is suitable for all kinds of gypsum base, reducing the sinking time of gypsum, reducing the drying shrinkage rate, and the wall surface is not easy to hollow and crack.

02. Application experiment test:

1. Water retention rate test: refer to the standard GB/T28627-2012 “Plastering Gypsum”, the water retention rate of light bottom plastering gypsum is ≥ 60%, when Kima gypsum-based hydroxypropyl methylcellulose is added 0.2% and 0.25% , has excellent water retention properties.

2. Wall hanging test: it is light and smooth when hanging, and can be molded at one time. The surface is delicate and soft, with brightness.

3. Anti-sagging test: It will not sag when it is hung in a single layer when it is hung in a thick layer, and it will not sag when it is hung in two or more layers (above 3cm), and it has excellent plasticity.

4. Strength test: After testing, Kima gypsum-based hydroxypropyl methylcellulose has excellent tensile bonding strength and compressive strength.

5. Spreading rate test: The spreading rate of gypsum base refers to the result obtained by measuring the wet bulk density of gypsum base. One ton of gypsum-based products has a wall area of 10mm thick. Using Kima gypsum-based hydroxypropyl methylcellulose products can greatly increase the coating rate, can cover more areas, can reduce labor intensity, save materials, and improve economic benefits.
