Green economy has been the direction of the modern enterprise development, and biodegradable materials is also more and more taken seriously.Productivity promote the council to research and develop the new biodegradable technology, in short ,the waste material and original material is the additive, and bringing plastic into scrap metal in order to break them down.
Developers firstly melt metal, and make the metal "sting technology" to stabilize the metal oxidants, to control the shelf life of the biodegradable fibers, make its reach to the ideal life.Because the metal is to cannot be mixed with glue itself, the organic matter is a more natural, such as plant and animal fat or oil, which is soap ingredients, play a catalytic role, the ingredients are prompted metal can be mixed with plastic.
Complete mixing part, research and development unit will add the mixture of traditional plastic granulator, through the program, such as machine frozen and smash it into granular, known as "die", and these mold become biodegradable fiber products of additives.Die maker just bought these grains and to join in the production process, no need to change any production line, can produce biodegradable hairnet, masks or surgical gown, etc.Non-woven polyester and polyethylene (PE) is the main ingredient, the research results, this time can make more than ninety percent of the non-woven fabric as biodegradable materials.
Technical personnel said, man-made fibers made of the additive, is "oxidation biological degradation technology of degradation, the decomposition of time in the sun only about six weeks, and biodegradable synthetic fiber decomposition speed, can be controlled by additive component.
And usually biodegradable synthetic fibers degradation mainly by two methods, the first is based on uv and high temperature oxidation, if the molecular weight is below 5000 units, it indicates that the molecules are "break up", composition allows bacteria to eat, return to nature, to complete biodegradation.Plastic molecular weight is about more than 20000 units, but bacteria can eat under the molecular weight of less than 5000 units.Compared with the international research institute also verified, through the development of new formulations of polyester fiber, its molecular weight (MV) can be reduced by 22000 units in at least 5000 units, according to effective make biodegradable.
