PLA (polylactic acid) ihe nwere ike imebi

Ihe mmeghe 

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. Chinese alias: polylactide (also known as polylactic acid) English name: polylactide, polylactic acid, abbreviated PLA English alias: polytrimethylene carbonate; 1,3-Dioxan-2-one homopolymerMolecular formula: (C3H4O2)n 

PLA polylactic acid na-eji lactic acid dị ka isi akụrụngwa, nke a na-enweta site na akpu, ọka, okpete na ahịhịa ndị ọzọ iji nweta starch na ọdịnaya shuga nke lactic acid nke enwetara site na gbaa ụka nje, ma mesịa mepụta polymer nwetara site na polymerization nke polylactic acid (PLA). ). Isi iyi nke akụrụngwa zuru oke yana mmeghari ohuru. 

The entire production process of polylactic acid and polylactic acid fiber does not involve any harmful substances. 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.

Nbibi PLA na-egosi 

Mmebi compost: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% 


Enwere ụfọdụ microbial 

mmebi nke ala ala:landfill conditions are different from composting conditions, so the degradation rate of PLA is slower, generally taking 2-5 years, but the degradation products do not pollute groundwater, do not damage plant growth, and do not waste arable land. degradation.Incineration : PLA has a small combustion calorific value, and the complete combustion products are carbon dioxide and water, which does not pollute the air. 


Ọnọdụ ụlọ ọrụ na atụmanya

The price of PLA before large-scale industrialization is $1000/kg. Later, large-scale production was achieved through the industrialization research of Professor Ramani Narayan's research group at Michigan State University. The technology is now industrialized by Natureworks. The largest manufacturer of PLA is NatureWorks in the United States, followed by China's Hisun Bio, whose current output is 100,000 tons and 5,000 tons respectively. PLA has many applications and can be used in extrusion, injection molding, film drawing, spinning and other fields. PLA fiber uses natural and renewable plant resources as raw materials, which reduces the dependence on traditional petroleum resources and meets the requirements of sustainable development of the international community. It has both the advantages of synthetic fibers and natural fibers, and at the same time has the characteristics of complete natural circulation and biodegradation. Compared with conventional fiber materials, corn fiber has many unique properties, so it has been widely valued by the international textile industry.
