Instructions for Glass Fiber Mesh Production Equipment (Simplified Version)

Glass fiber mesh production equipment is used to manufacture alkali-resistant, high-strength mesh products, which are suitable for scenarios such as building exterior insulation, tile adhesion, and crack repair. The core process consists of "fiber pay-off - weaving/forming - glue coating & curing - winding", and the equipment is mainly divided into two types of production lines: weaving-type and forming-type. The key information is organized as follows:

I. Core Equipment Types and Key Components

(I) Weaving-Type Production Line (Mainstream, for Conventional Warp-Weft Mesh)

Multi-Axis Fiber Pay-Off Stand: Synchronously releases multiple sets of glass fiber yarns (mainly alkali-free glass fibers). Independent tension controllers ensure uniform tension (tension error ≤ 5%) and prevent yarn breakage or slack. It is equipped with yarn breakage detection sensors.

Warp-Weft Weaving Machine: Interlaces warp (longitudinal) and weft (transverse) glass fiber yarns at a set density (commonly 8-20 meshes per inch). It supports plain weave, twill weave, and other weaving patterns, with adjustable width (0.5-3m). A servo drive system ensures synchronized interlacing speed of warp and weft yarns.

Glue Coating & Impregnation Machine: Uniformly applies alkali-resistant adhesive (e.g., modified acrylate adhesive, epoxy resin adhesive) to the woven mesh blank. The glue application amount (50-150g/㎡) is adjustable. A glue circulation system reduces waste and improves the alkali resistance of the mesh.

Continuous Curing Oven: Uses staged temperature control (preheating: 80-90℃, curing: 100-120℃, cooling: ≤40℃) and completes curing within 3-5 minutes (curing degree ≥90%). A Teflon mesh belt is used to prevent mesh adhesion.

Traction & Winding Machine: Pulls the mesh at a constant speed and winds it into rolls with a maximum diameter of 1.2m. It is equipped with an edge alignment device (alignment error ≤2mm) to prevent mesh wrinkling or tensile deformation.

Auxiliary Equipment: Includes a yarn pretreatment machine (for impurity removal and drying, moisture content ≤0.5%), online detectors (for monitoring mesh count and glue amount), an optional slitting machine (slitting accuracy ±1mm), and a waste collection machine.

(II) Forming-Type Production Line (for Non-Woven/Composite Mesh)

The core difference lies in the "forming process"; other equipment is common with the weaving-type production line:

A fiber lapping machine combs yarns into a web and forms a blank through cross-lapping (thickness: 0.1-0.5mm, width: 0.8-3m);

Equipped with a needling/bonding machine: The needling machine uses mechanical reinforcement, while the bonding machine uses hot-melt bonding. It is suitable for high-loft, large-aperture mesh (20-50 meshes per inch).

II. Core Technical Parameters (Mainly for Weaving-Type)

Production Speed: 5-20m/min (faster for fewer meshes and narrower width; e.g., 15-20m/min for 8-12 meshes/inch and 1m width);

Mesh Specifications: Width 0.5-3m (customizable), mesh count 6-30 meshes per inch, grammage 80-500g/㎡;

Finished Product Accuracy: Mesh count error ±0.5 meshes, width error ±3mm, grammage error ±5%;

Alkali Resistance: Tensile strength retention rate ≥80% after 28 days of immersion (compliant with GB/T 26748 standard).

III. Operation and Maintenance Key Points

(I) Operation Process

Pre-Production: Inspect yarn quality, adjust pay-off tension (20-50N), prepare adhesive, and preheat the curing oven (30 minutes in advance);

Operation: Pay-off → Weaving → Glue Coating → Curing → Traction & Winding → Sampling Inspection;

Monitoring: Prevent yarn breakage, uneven glue amount, and local overheating of the curing oven.

(II) Maintenance and Safety

Daily: Clean glue coating rolls, glue scrapers, and curing oven conveyor belts; inspect tension controllers and edge alignment devices;

Regular: Check needle wear weekly (replace if wear exceeds 0.2mm), clean curing oven pipes monthly, and calibrate detectors quarterly;

Safety: Wear solvent-resistant gloves during glue coating, prohibit flammable materials near the curing oven, and do not touch the operating traction rolls/winding machine.

IV. Selection Recommendations

Scenario Adaptation: For exterior wall insulation, select 10-16 meshes/inch and 100-200g/㎡ (prioritize alkali resistance); for tile adhesion, select 8-12 meshes/inch and 80-150g/㎡ (prioritize flexibility); for crack repair, select 16-25 meshes/inch and 200-300g/㎡ (prioritize strength);

Selection Factors: Determine speed based on production capacity (e.g., 1-2 lines required for annual demand of 1 million ㎡ with 1m width and 10m/min speed); determine equipment adjustment range based on specifications; in areas with strict environmental regulations, prioritize equipment with glue recovery and waste gas treatment functions.

V. Industry Standards

Equipment: Compliant with Technical Specifications for Glass Fiber Mesh Production Equipment;

Finished Products: China GB/T 26748, International ISO 9229. Core indicators: Warp tensile strength ≥1200N/50mm, weft tensile strength ≥1000N/50mm.
