DPC Moisture Barrier Membrane Production Line

DPC (Damp Proof Course) moisture barrier membrane is mainly made of PE/HDPE/LLDPE polymer materials, and also includes PVC, EVA and modified asphalt types, whose core function is to block the capillary rise of groundwater vapor. Haiming Machinery DPC Moisture Barrier Membrane Production Line takes extrusion casting/blown film + embossing/composite as the core process, with mature technology and stable operation. The produced DPC moisture barrier membrane can meet the moisture-proof and vapor barrier needs of various building scenarios, and the production line is suitable for large, medium and small enterprises.

I. Main Product Structure of DPC Moisture Barrier Membrane

1. Pure PE/HDPE Type (Most Commonly Used)

Surface Layer

Smooth/embossed (diamond grid/dot, enhancing mortar adhesion)

Main Body

PE/HDPE/LLDPE base material (0.2–2.0mm)

Functions

Moisture proof and vapor barrier

Anti-aging and acid-alkali resistance

2. Composite Reinforced Type (High-end)

Surface Layer

Embossed PE

Reinforcement Layer

Non-woven fabric/glass fiber cloth (improving tensile strength and tear resistance)

Bottom Layer

PE/HDPE

Application

Heavy-duty foundations and underground projects

3. Other Types

PVC/EVA Type

Weather resistance and good flexibility

Modified Asphalt Type

Self-adhesive, suitable for asphalt base surfaces

II. Main Production Process

Extrusion Casting Method (High Flatness, Stable Width)

Step 1: Raw Material Batching

PE/HDPE + masterbatch + antioxidant + UV stabilizer

Step 2: Melting and Plasticizing

Single-screw extruder → melting and plasticizing

Step 3: Casting Film Formation

Hanger-type die → casting film formation

Step 4: Shaping

Three-roll calendering/cooling shaping (including embossing roll)

Step 5: Auxiliary Processing

Traction, deviation correction, edge trimming

Step 6: Thickness Detection (High Configuration)

Online thickness measurement (laser/β-ray)

Step 7: Winding

Dual-station automatic winding → finished product

Process Advantages

Uniform thickness and flat surface

Embossing available

Width up to 1.8–8m, suitable for large-volume building coils
