In anti-corrosion flooring construction, dry-spread materials typically contain high-grade cement, quartz sand, or metal aggregates. During the high-speed spreading process of the concrete spreader, a large amount of floating dust (such as silica dust) is easily generated. This not only affects worker health (risk of silicosis) but also contaminates surrounding expensive production equipment.

The following are the mainstream dust control and environmental protection measures in concrete spreader construction:

1. Dust Suppression Design of the Concrete Spreader Itself

Modern automated concrete spreaders (especially ride-on or large laser-leveling spreaders) are designed with dust suppression in mind:

Enclosed Hopper: Changing the traditional manual throwing method, materials are stored in an enclosed hopper and discharged via a bottom screw conveyor or roller, greatly reducing the material's exposure time to air.

Windproof Enclosure/Soft Curtain: Anti-static rubber soft curtains are installed at the discharge port, as close as possible to the concrete surface (maintaining a distance of 10cm-15cm), confining dust to a very small local space.

Low-Level Discharge Technology: The spreader's boom has an adjustable height, allowing for "ground-hugging" discharge, reducing airflow disturbance caused by free fall of materials.

2. Comprehensive Environmental Protection Measures at the Construction Site

A. Humidity Control (Key Point)

Substrate Water Control: Strictly control the "water discharge" state of the concrete. Utilize the concrete's own seepage water to moisten freshly applied powder.

Environmental Humidification: Deploy mobile water mist fans or micro-mist dust suppression systems around the construction area.

Note: Water mist must not be sprayed directly onto unpainted concrete surfaces to avoid altering the local water-cement ratio and affecting corrosion resistance.

B. Vacuum Cleaning Assistance

Localized Vacuuming: For manual replenishment areas in corners, a high-grade industrial vacuum cleaner with a HEPA filter must be used for simultaneous vacuuming.

Collection and Disposal: Dry powder scattered along the spreader's path should be disposed of promptly to prevent it from being re-entered into the air due to the high-speed rotation of the power trowel.

3. Green Construction Management Standards

According to national and industry environmental protection requirements (such as the "Construction Site Environmental and Sanitary Standards"), the following operations must be performed:

Measures Category Specific Operational Procedures: Objectives
Packaging Handling Using large bags (ton bags) in conjunction with an automatic feeding machine is mandatory to reduce the instantaneous release of dust when opening small bags. Reduce start-up dust by over 70%
Waste Management Empty bags remaining after feeding must be immediately placed into sealed recycling bags; littering or burning is strictly prohibited. Prevent secondary pollution
Personnel Protection Construction personnel must wear P100/N95 dust masks and windproof goggles. Protect occupational health and safety
Enclosed Construction When working indoors, a negative pressure ventilation system must be established or a large centrifugal fan must be used to exhaust filtered air. Prevent dust from spreading to other clean areas

4. Special Environmental Requirements for Corrosion-Resistant Flooring

In the construction of acid-resistant, oil-resistant, and other special flooring materials, dry-spread mixes may contain special chemical additives:

Water Solubility Monitoring: It is strictly forbidden to spray excessive water directly after spreading the mix to reduce dust, as this will lead to the loss of effective anti-corrosion components and contaminate the on-site drainage system.

Material Selection: Pre-granulated dry-spread mixes should be given priority. These materials have low fly ash content, a heavy granular texture, and naturally generate less dust.

Next Steps

If you are undertaking renovations or refurbishments within a pharmaceutical, food, or precision electronics factory, dust control requirements are extremely stringent.

 

Would you like me to recommend a "clean-state" construction and coordination plan? Or are you preparing for an on-site inspection by the environmental protection bureau and require relevant compliance documentation?
