Melamine tableware is made of melamine powder in high temperature and high pressure. In the production process of tableware, environmental problems such as dust, exhaust gas, noise, solid waste, etc. are generated, so how to reduce the environmental pollution caused? Tableware factories can take the following precautions.
| Type | Emission source | Name of pollutant | Prevention measures |
| atmospheric pollutant | Preheating, hydroforming | formaldehyde | Gas gathering facility, activated carbon adsorption device, exhaust cylinder, exhaust fan |
| Trimming and polishing | particulates | Bag dust collector, exhaust cylinder, exhaust fan | |
| Solid Waste | Industrial solid waste | Defective products, hydroforming scraps | Sell comprehensive utilization or recycle |
| Noise | Production equipment | Equivalent sound level | Basic shock absorption, sound insulation of plant |
1. Water pollution control measures
The Cooling water in the chiller is recycled which will not be discharged to the outside, and will not cause water pollution.
2. Exhaust gas treatment measures
The organic waste gas generated during preheating, hydroforming and injection molding is collected by the gas collection equipment and processed by the activated carbon adsorption device. It is discharged through the exhaust pipe, which is 5m above the highest building, and the radius of the surrounding area is 200m. After the bag-type dust collector processes the dust, the exhaust gas is discharged through a high-altitude exhaust pipe of not less than 15m. After treating the exhaust gas, it has little effect on the air in the workshop and the surrounding environment.
3. Noise pollution control
(1) Select low-noise equipment and take basic vibration-damping measures when installing the equipment.
(2) Arrange production equipment reasonably, high-noise equipment should be far from the factory boundary.
(3) During the production process, close the doors and windows of the workshop. In the daily production and operation process, the maintenance of mechanical equipment should be strengthened to ensure that the mechanical equipment is in a normal operating state and that the impact of noise on the surrounding environment is within an acceptable range.
4. Solid waste treatment measures
Industrial solid waste collection, which collects waste and defective products generated by hydraulic pressure, and sells it to non-edible tableware production. The dust collected by cloth bags and dust cleaned in the workshop can be considered for recycling to avoid environmental pollution, and certain Social benefits are feasible.
The raw materials produced by Huafu Chemicals, such as melamine molding compound and melamine glaze powder are of high quality and high yield, and will not cause a lot of solid waste pollution. They all passed the SGS and Intertek test and 100% food contact. Welcome to inquire and visit Quanzhou Huafu Chemical Factory.
