Polylactic acid (PLA) is a novel biodegradable material made from starch raw materials proposed from renewable plant resources such as corn. The starch raw material is fermented into lactic acid, which is then converted into polylactic acid through chemical synthesis. It has good biodegradability and can be completely degraded by microorganisms in nature after use, eventually producing carbon dioxide and water without polluting the environment, which is very beneficial to protecting the environment and is recognized as an environmentally friendly material.
PLA has excellent biodegradability, and can be completely degraded by microorganisms in the soil within two years after being discarded, producing CO2 and H20 without polluting the environment. At the same time, polylactic acid (PLA) has good mechanical processing properties and can be used for most synthetic plastics.
Advantages of Dowell Polylactic Acid (PLA):
1. Polylactic acid has excellent biodegradability. It can be completely degraded by microorganisms in the soil within one year after being discarded, and produces carbon dioxide and water without polluting the environment. Truly "originate from nature, return to nature"!
World carbon dioxide emissions According to news reports, the global temperature will rise to 60°C in 2030. Common plastics are still processed by incineration and cremation, causing a large amount of greenhouse gases to be released into the air, while polylactic acid is buried in the soil and degraded, resulting in Carbon dioxide directly enters the soil organic matter or is absorbed by plants, and will not be discharged into the air, and will not cause the greenhouse effect.
2. Polylactic acid is suitable for various processing methods such as blow molding and injection molding. It is easy to process and widely used. It can be used to process various food containers, packaged food, fast food lunch boxes, non-woven fabrics, industrial and civil fabrics from industrial to civil. Then it can be processed into agricultural fabrics, health care fabrics, rags, hygiene products, outdoor anti-ultraviolet fabrics, tent fabrics, floor mats, etc. The market prospect is very promising. It can be seen that its mechanical and physical properties are good.
3. The basic physical properties of polylactic acid (PLA) and petrochemical synthetic plastics are similar, that is to say, it can be widely used to manufacture various application products. Polylactic acid also has good gloss and transparency, comparable to films made of polystyrene, which other biodegradable products cannot provide.
4. Good compatibility and degradability. Polylactic acid is also widely used in the medical field, such as the production of disposable infusion sets, surgical sutures, etc., and low-molecular polylactic acid as drug sustained-release packaging agents.
5. Dowell PLA has the best tensile strength and elongation. Polylactic acid can also be produced by various common processing methods, such as: melt extrusion molding, injection molding, blown film molding, foam molding and vacuum molding, which are widely used at present. The polymers used have similar forming conditions and in addition it also has the same printing properties as conventional films. In this way, polylactic acid can be made into various application products according to the needs of different industries.
6. When polylactic acid (PLA) is incinerated, its combustion calorific value is the same as that of incinerated paper, which is half of that of traditional plastics (such as polyethylene), and incineration of polylactic acid will never release toxic gases such as nitrogen and sulfide. . The human body also contains lactic acid in monomeric form, which indicates the safety of this decomposing product.
7. Polylactic acid (PLA) film has good air permeability, oxygen permeability and carbon dioxide permeability, and it also has the characteristic of isolating odor. Viruses and molds are easy to attach to the surface of biodegradable plastics, so there are doubts about safety and sanitation. However, polylactic acid is the only biodegradable plastic with excellent antibacterial and anti-mildew properties.
With increasing emphasis on resource conservation and environmental protection, can plastics be replaced and upgraded? The widespread use of degraded biomass material - polylactic acid (PLA) can not only alleviate the resource dependence caused by the "oil crisis", but also completely eradicate white pollution.
