Q:What’s Your Sample Policy Of HPMC?
A: 100-500g free sample is available for depending on your needs.
Q:What is the dosage of HPMC in C1 and C2?
A: For C1, we suggest 2kg-2.5kg per ton. And 2.5kg-3kg per ton for C2!
Q:What are the applicable ranges of different grades of tile adhesive?
A:
C 1:Suitable for ceramic tiles and vitrified tiles with low water absorption rate and Laying natural stone materials such as ceramic tiles, glazed tiles, marble, etc.
C 1 T:Suitable for ordinary ceramic tiles and ceramic mosaics with a water absorption rate greater than 6%; Decorative ceramic tiles with a water absorption rate of ≥ 0.2% and a size of ≤ 400 × 800mm.
C 2 T:Suitable for decorative tiles with a water absorption rate of 0.5% <E < 3%, or 0.2% < E < 0.5%, and a size ≤ 600 × 1200mm.
C 2 E S 1:Suitable for ceramic slabs, rock slabs, etc. with a size not exceeding 2.4m * 1.2m for indoor wall pasting.
C 2 T S 1:Suitable for pasting ceramic slabs, rock slabs, etc. with a size not exceeding 2.4m * 1.2m on indoor walls.
Q:What are the differences in the thickness of different masonry mortars?
A: General purpose masonry mortar:mortar layer thickness more than 5mm. Thin-layer masonry mortar:mortar layer thickness less than 5mm.
Q: What should be considered when choosing HPMC for different applications in gypsum-based mortars?
A:
Focus on type, performance, and viscosity:
Type Selection:
Choose HPMC designed specifically for construction. These products offer better thermal stability and longer open times.
Performance Considerations:
Water Retention: Ensures moisture stays within the mortar, enhancing quality.
Adhesion: Improves bonding to substrates, increasing structural integrity.
Crack Resistance: Reduces shrinkage cracks during drying, improving durability.
Viscosity Guidelines:
For standard applications, use HPMC with a viscosity of 4000 to 8000 mPa·s for good workability and water retention.
For improved flow and extended open time, opt for 8000 to 15000 mPa·s viscosity.
Q:What important roles does Hydroxypropyl Methylcellulose (HPMC) play in gypsum-based mortars and drywall production?
A: HPMC serves multiple critical functions in gypsum-based materials:
Enhanced Workability: Increases the lubricity and plasticity of the mortar, making it easier to apply and smooth out.
Improved Water Retention: Reduces rapid surface moisture evaporation, ensuring uniform water distribution within the material, thus enhancing product quality.
Increased Adhesion: Enhances the mortar’s bonding to substrates, improving structural stability and durability.
Controlled Setting Time: Regulates open time and setting speed, providing a flexible working window for application.
Crack Resistance: Helps minimize shrinkage cracks during drying, improving durability and aesthetic appeal.
Optimized Surface Finish: Improves the smoothness and consistency of the final product.
