Hydroxypropyl Methyl Cellulose (HPMC)

Hydroxypropyl Methyl Cellulose (HPMC)

1. Low viscosity type (50000 mPa · s)
Application scenarios:

Machine sprayed mortar: reduces pumping resistance by 30%, compatible with screw pumps/plunger pumps

3D printing building materials: fine printing with layer thickness of 1-3mm, flow stability of ± 5%

Thin layer repair: 1-5mm crack filling, anti sagging thickness ≥ 8mm

Technical parameter comparison:

Indicator Industry Standard Products Our company’s products
Dissolving time (cold water) 8-10 minutes 3-5 minutes (pre gelatinization process)
Gel temperature 60-65 ℃ can be customized 50-65 ℃
Heavy metal residue ≤ 30ppm ≤ 10ppm
Competitive advantage:
🔹 Anti clogging tube design: 80 mesh screening rate ≥ 95%, reducing the risk of nozzle clogging
🔹 Tropical climate adaptation: the temperature of gel can be lowered (50 ℃) to avoid the failure of high temperature gel
🔹 Quick construction: can be polished in 15 minutes (thin layer putty application)

2. Medium viscosity type (100000 mPa · s)
Application scenarios:

Ceramic tile adhesive: opening time 20-30 minutes (EN 1346 standard)

Cement based plastering: plastic shrinkage cracks reduced by 40%

EIFS insulation system: substrate water absorption rate ≤ 3% (ASTM C97)

Performance optimization:

Anti sagging performance: 4mm tooth scraping construction without slipping for 10 minutes (EN 1308)

Compound synergy: Combined with starch ether, the thixotropy index is increased to 6.0-6.5

Dust control: Pre wetting treatment of particle surface, reducing dust by 60% through agitation

Customization options:
⊙ Slow dissolving type: Delayed hydration for 20 minutes, suitable for high temperature and dry environments
⊙ Highly alkaline adaptation type: The water retention rate is still ≥ 85% under pH 13 environment

3. High viscosity type (200000 mPa · s)
Application scenarios:

Self leveling mortar: 1-hour water retention rate ≥ 95% (20mm flowability)

Thick layer masonry: Vertical construction thickness ≤ 20mm without sagging

Waterproof mortar: water absorption rate ≤ 2.5% after compounding with hydrophobic agent

Technological breakthrough:

Shear thinning characteristics: Thixotropic index 6.3 (Brookfield RVT test)

Enhanced alkali resistance: viscosity retention rate ≥ 90% in Ca (OH) ₂ saturated solution

High purity guarantee: Ash content ≤ 1.5% (better than the national standard GB/T 29594)

Special modified models:
🔸 Early strength type: accelerates cement hydration, increases 24-hour compressive strength by 15%
🔸 Anti enzymatic type: β – glucanase tolerance increased by 10 times, shelf life extended to 24 months
