In order to reduce emission, SIGHTONE has made great efforts during the process of artificial marble tiles production, consequently saving energy, reducing emission and protect our environment. Then, what are these efforts?
Waste Water Utilization
The main raw material of artificial marble is calcium carbonate powder (powder of offcut) and resin. It is a green product of resource recycling. It is made by the high frequency high pressure pressing equipment in vacuum.The whole production process has no calcination, no high energy consumption; Water use is internal recycling, no extra external discharge.
How:
1. The production sewage from the presser, gang saw , polishing machine and intensive processing workshop flows to the sewage pool of the sewage treatment system through the ditch pipe network, and the Defoamer, precipitant and other chemicals are added in front of the sewage pool.
2. The slurry pump pumps the sewage from the sewage pool to the sedimentation tower, and the clean water after three stages step-by-step sedimentation flows back to the gang saw and intensive processing workshop for recycling use; or it flows back to the clear water tank and then to the 4# sedimentation tower, and then the clear water after two-stage sedimentation flows back to the polishing and the intensive processing workshop for recycling use.
3. The sludge precipitated in the sedimentation tower is discharged to the slurry discharge tank through the pipeline, and then pumped by the plunger pump to the filter press to extract the slurry. The wasted water produced by the sludge is returned to the sewage pool, and the waste residue is transported to the treatment unit for recycling use.
How: use the fan to collect dust and wasted gas from the discharge bin, mixer, vacuum pump and pressing bin of the compressor production line.
After collection, the wasted gas is sent into the oxidation tower of the wasted gas treatment system, and a strong chemical oxidant solution is used within an acid condition.
The organic matter is oxidized into carbon dioxide and water through two oxidation towers, and then the oxidized gas will enters the alkali liquor tower for the absorption of acid organic matter.
After all, the gas treatment is up to standard and will be discharged at a high altitude. In hence, our products are environmentally friendly, free of radiation and radioactive substances, also is low carbon environmental protection · health energy-saving green building materials.
● Recyclable and Sustainability
By using modified and qualified adhesive tape for back, the wood panels can be peel from wall without any destroy to wall and product itself, making it completely recyclable at the end of its life cycle. Self adhesive wood also an exceptionally sustainable choice.
