Introduction of PLA
PLA (polylactic acid) biodegradable material refers to a class of materials that are degraded by the action of microorganisms such as bacteria, molds (fungi) and algae that exist in nature.
PLA polylactic acid uses lactic acid as the main raw material, mainly obtained from cassava, corn, sugarcane and other herbs to obtain starch and sugar content of lactic acid obtained by bacterial fermentation, and finally forms a polymer obtained by polymerization of polylactic acid (PLA). The source of raw materials is sufficient and renewable.
It is a kind of polymer material with excellent performance, which can be completely decomposed by environmental microorganisms after being discarded, and finally be inorganicized and become an integral part of the carbon cycle in nature.
Natural Properties and Advantages
*The pH value is around 6, which is weakly acidic.
*Inhibition of mites, the inhibition rate of the anti-mite performance of the test data is 71.39%, and the conclusion is that it has anti-mite effect.
*The antibacterial effect is obvious, and the loss rate of Staphylococcus aureus, Candida albicans and Escherichia coli is more than 98%. (SGS authoritative testing)
*No antibacterial, anti-mite drugs or other chemical substances are added in the production process, which is completely the performance of its natural properties.
*Natural self-extinguishing property: non-flammable, and the oxygen limit index is higher than that of polyester and nylon.
*The thermal insulation performance is 1.8 times greater than that of high-quality cotton wick. (Test data)
*Good rebound, strong bulkiness, smooth feel, quick drying, UV resistance.
Application Sustainability
*Reducing the use of petrochemical materials and reducing carbon emissions
*Use natural and renewable raw materials (such as: vegetable starch, sugar cane, straw fiber, etc.)
*Adopt green and safe manufacturing process
*Compatible with existing solid waste management systems
*Burnable - completely clean burn
*Landfillable - no leachate or toxic and hazardous materials
*Compostable
*Recyclable for processing into monomers or other products
*Create a good living environment for future generations and improve the quality of life
PLA Degradation Instructions
Compost degradation: PLA can achieve full biodegradation within 180 days under compost degradation conditions, and the final degradation products are carbon dioxide and water. The composting conditions are as follows:
The temperature is 58±2℃
Humidity is 98%
Certain microorganisms
Landfill degradation: Landfill conditions are different from composting conditions, so the degradation rate of PLA is slow, generally taking 2-5 years, but the degradation products do not pollute groundwater, do not damage plant growth, and do not waste arable land, and ultimately it is still fully degraded.
Incineration: PLA has a small combustion calorific value, and the complete combustion products are carbon dioxide and water, which does not pollute the air.
