Product Description: Cold Chain Warehouse Waterborne Environmental Protection Moisture-Proof Mortar Floor
1. Introduction
In the realm of cold chain logistics, maintaining precise environmental conditions is critical to preserving the integrity of perishable goods. A key challenge in cold storage facilities lies in managing moisture and condensation, which can compromise product quality, structural integrity, and operational efficiency. To address these challenges, the Waterborne Environmental Protection Moisture-Proof Mortar Floor has been engineered as a specialized solution for cold chain warehouses. This innovative flooring system combines advanced moisture-resistant technology with eco-friendly waterborne materials, delivering a durable, hygienic, and sustainable surface that meets the stringent demands of low-temperature environments. Below is a detailed overview of its features, benefits, and applications.
2. Technical Specifications & Composition
The mortar floor is formulated using a proprietary blend of waterborne epoxy resins, modified cementitious binders, and high-performance aggregates. Key components include:
- Waterborne Epoxy Resin: Acts as the primary binder, offering exceptional adhesion, chemical resistance, and flexibility even at sub-zero temperatures. The water-based formulation eliminates volatile organic compounds (VOCs), reducing environmental impact and improving air quality during application.
- Modified Cement: Enhanced with polymers to improve workability, reduce shrinkage, and increase bond strength. This ensures long-term durability under thermal cycling and heavy loads.
- Specialty Aggregates: A mixture of graded silica sand and recycled materials, providing optimal compressive strength and dimensional stability. The aggregates are treated with hydrophobic additives to repel moisture at the molecular level.
- Moisture-Blocking Additives: Includes silane-based coupling agents and acrylated copolymers that form a dense, impermeable matrix within the mortar, preventing capillary absorption of water.
3. Core Features & Advantages
3.1 Superior Moisture Resistance
- Capillary Blocking Technology: The hydrophobic additives create a barrier against moisture penetration, even under high-humidity conditions typical in cold stores (85%-95% RH).
- Vapor Permeability Control: The system allows controlled release of moisture vapor from the substrate while preventing liquid water ingress, mitigating condensation risks.
3.2 Thermal Stability
- Cryogenic Durability: Tested for performance at temperatures as low as -30°C, the mortar maintains its integrity without cracking, delaminating, or losing adhesion.
- Thermal Shock Resistance: Withstands rapid temperature fluctuations between -25°C and +10°C without structural failure.
3.3 Environmental Benefits
- Zero VOC Emissions: Water-based formulation eliminates harmful fumes, improving worker safety and complying with LEED/BREEAM standards.
- Recyclable Content: Incorporates post-industrial recycled aggregates (up to 30% by weight), reducing carbon footprint.
- Low Embodied Energy: Waterborne manufacturing processes consume 40% less energy compared to solvent-based alternatives.
3.4 Hygienic Properties
- Non-Porous Surface: The dense matrix prevents bacterial growth and mold formation, critical for food-grade storage facilities.
- Seamless Installation: Eliminates joints where contaminants can accumulate, simplifying cleaning protocols.
3.5 Mechanical Performance
- High Compressive Strength: >40 MPa (5800 psi) at 28 days, supporting heavy forklift traffic and palletized loads.
- Abrasion Resistance: Surface hardness >6H (Mohs scale), resisting wear from pallet jack wheels and foot traffic.
- Chemical Resistance: Withstands exposure to defrosting agents, cleaning chemicals, and food acids.
4. Application Scenarios
This mortar system is ideal for:
- Blast Freezers: Withstands extreme temperature gradients during rapid freezing cycles.
- Automated Storage/Retrieval Systems (AS/RS): Provides a flat, level surface for precise machinery operation.
- Food Processing Zones: Facilitates HACCP compliance with easy-to-clean, non-absorbent surfaces.
- Pharmaceutical Storage: Maintains controlled environments for temperature-sensitive medications.
- Cold Chain Distribution Centers: Ensures product integrity during loading/unloading operations.
5. Installation Process
5.1 Surface Preparation
- Substrate Requirements: Concrete slab moisture content <95% RH (tested via ASTM F2170), with surface profile CSP-3 minimum.
- Primer Application: Waterborne epoxy primer applied at 200-300 μm DFT to enhance adhesion.
5.2 Mortar Placement
- Mixing: Pre-bagged components blended in forced-action mixers with controlled water addition.
- Pouring: Self-leveling or trowel-applied to 4-6 mm thickness, depending on load requirements.
- Curing: Ambient temperature cure (10-30°C) with controlled humidity for 72 hours.
5.3 Topcoat Options
- Polyurethane Sealant: For enhanced chemical resistance in washdown areas.
- Anti-Slip Aggregate Broadcast: Incorporates quartz or aluminum oxide particles for safe pedestrian/vehicle traffic.
- UV-Resistant Finish: For cold rooms with translucent roofing to prevent color fading.
6. Maintenance & Lifespan
- Cleaning: pH-neutral detergents with soft brushes/mops. Avoid abrasive cleaners.
- Recoating: Every 5-7 years under normal traffic conditions, with localized repairs possible.
- Service Life: >15 years with proper maintenance, significantly longer than conventional cementitious floors.
7. Compliance & Certifications
- Environmental Standards: Complies with REACH, RoHS, and California Proposition 65.
- Building Codes: Meets ASTM C1329 (cracking resistance), ASTM C1202 (water permeability), and EN 13813 (adhesion strength).
- Hygienic Certifications: NSF/ANSI 51 (food zone compliant), ISO 22196 (antibacterial effectiveness).
