From 1907 the first kind synthesizes plastic birth, to now of all sorts of sort plastic each corner that enters people life, make the one part of human society, plastic industry has taken the harships run of a century. However, after 100 years today, we are being enjoyed plastic when brought convenient and comfortable life, all sorts of problems that also must face it to cause, of be the first to be affected is environmental pollution —— traditional and plastic chemical composition is stable, very difficult degradation disappears. Be aimed at this problem, each countries came on stage to restrict the code that plastic products uses in succession, use what for instance our country began to execute on June 1 this year about restricting production to sell plastic the announcement of shopping bag. In the meantime, industrial group also searchs traditional and plastic substitute in effort ceaselessly, among them, get together lactic acid (PLA) because study time is long, the technology is relatively mature, received most wide attention and application, hopeful is being packed, the project is plastic wait for a domain to replace a tradition plastic. The oil with the tradition base plastic and different, get together lactic acid is the lactic acid that send sticky ferment by plant starch and gets aggregate and into, this is a kind but renewable resources. In the meantime, get together lactic acid has good live thing but degradation sex, in using the plastic product that it makes to be buried at soil after discard, can arrive in 6 months inside 12 months automatic degradation is water and carbon dioxide, far to environmental harm be less than a tradition plastic.
Get together lactic acid still has better treatment performance, what can apply to a tradition is crowded piece, note model, blow the treatment method such as model. However, because get together the molecular structure with unique lactic acid, it is in treatment process as temperature elevatory, stickiness number will decline quickly, cause fuse-element intensity to drop at the same time, fuse-element burst, flabby, output falls low problem. These problems are in the treatment process of intensity of fuse-element of a few need, if blow model, epispastic in, appear highlight particularly. Accordingly, how to rise get together the fuse-element intensity of lactic acid, improve its to machine function to apply foreground in order to extend its, become a when be placed before industry new issue.
Company of collect door Ha Si (RohmandHaas) the chemical supplier that is a world-class, in the meantime, also be a company that has social sense of responsibility extremely, devote oneself to all along but the application of degradation material and promotion, with world-renowned but business of degradation material production also is having extensive and close connection. Last year, company of collect door Ha Si and world are the greatest get together lactic acid produces business (Naturework) collaboration, rolled out use technically at getting together transparent application system adds lactic acid the PARALOIDTMBPM of modified of pliable but strong - 500. Nowadays, depending on the abundant technology base in domain of plastic processing aid and rich experience, company of collect door Ha Si to get together the processability of lactic acid can offer improvement plan ——PARALOIDTMBPMS - 255, 265.
