China is the first carbon dioxide biodegradable plastic bag
Core tip: in the cnooc chemical company of an exciting news, the company in collaboration with the Chinese academy of sciences changchun should turn carbon dioxide degradable plastics (PPC) important progress downstream products application development project, researchers succeeded in carbon dioxide degradable material blown film and made into environmental protection bags, the first in the world.
In the cnooc chemical company of an exciting news, the company in collaboration with the Chinese academy of sciences changchun should turn carbon dioxide degradable plastics (PPC) important progress downstream products application development project, researchers succeeded in carbon dioxide degradable material blown film and made into environmental protection bags, the first in the world. This green plastic bag is encouraging after the introduction of China's "restrictions on plastic".
It is understood that after the use of this plastic bag, it can be completely biodegradable under the condition of compost, which will not have any effect on the environment. In the future, China's cnooc engineering technology center will also cooperate with relevant scientific research units, focus on developing high barrier film, made more rigid, more thin film, meet the requirement of food packaging, and expand the application field of carbon dioxide degradable plastics.
The reduction and utilization of carbon dioxide has been a difficult problem for all mankind. As temperatures rise, carbon dioxide is a potential resource. To this end, cnooc is the first company to expand the production of 3,000 tons of PPC equipment in its chemical company. To tie in with the project production plant construction, expand the carbon dioxide plastic products market, the company in plant construction at the same time, also the application of PPC downstream products series research, the key to develop carbon dioxide in the field of degradable plastics in the packaging application test was studied. At the same time, the company has cooperated with changchun institute of Chinese academy of sciences to give full play to the excellent performance of carbon dioxide high barrier and low permeability.
It is understood that after the project started in 2007, has carried on the purification of carbon dioxide based plastic, preliminary modification and sealing test, scale pure technology research completed the PPC ash content is less than 1000 x 10-6 with less than 50 x 10 - two refining process route design, through the sealing side of PPC, blend and controllable crosslinking test. In early may, a 100kg film blowing film was carried out at nantong huasheng co., ltd. in jiangsu province, stabilizing the film with 0.03mm. Because of the blown film products needs to be improved in terms of impact, tear resistance, project team will increase the resilience of PPC material immediately as the research focus of blown film, the formulation and process of PPC material is improved and optimized. At the end of June, 375 kg of membrane modified PPC materials were used in the industrial blown film test at nantong huasheng company and successfully made plastic bags of thin film.
