Degradable plastics and waste plastic problem

It is known as light degradable plastic. U.S. housing in general have a larger yard, so mowing the lawn, trees and garden waste accounts for 18% a whole litter to speed up the progress of garbage mixed experiments, for which some states and regions must be defined into the degradation of garden waste out of plastic garbage bags. In Japan, incineration of garbage can be handled basically burned. Therefore, do not specifically use the degradation of biodegradable plastics and light plastic garbage bags. In addition, non-combustible garbage usually buried way deep when the soil covering the top with no sun exposure, which, even if the use of biodegradable plastic will not break down light. Therefore, the light production of biodegradable plastic garbage bags did not make any sense. Development of Biodegradable Plastics Biodegradable Plastics Another application field is to solve the problem of marine pollution. According to information reported; bowl of instant noodles in the sea foam polystyrene containers were discarded flakes were eating fish or seabird deaths were reported. In order to solve marine environmental problems, in January 1989 began implementation of international treaties, is strictly prohibited discarded plastic products In the ocean, so as not to drift, Fu pollution of the sea. Now, artificial substances in the environment the tendency to take further measures, in particular, to make more stable the degradation of plastic to make it like wood, paper, natural substances in the environment as recycling (in other words, allow it to rot and become food for microorganisms) Japanese Biochemical Industry Division of MITI organized the .,, a variety of biodegradable polymers in the development of plastics, and some have been put into industrial production. 7 t tip of a butterfly gate together, west point west kettle rough, J,louboutin københavn, March 1992, Los Angeles City Ana Han Convention Center 37 Technology Association, an international advanced materials (SAMPE) Conference and Exhibition is rich in content, I engaged in the industry point of view according to the summary reports on the cutting edge Recovering materials (ACM) in the development and processing applications. 1 . Alexandra formaldehyde resin material Xiamen Branch of its phenolic resin complex structure of Taiwan itself has flame resistance, it does not require added flame retardants to have very low flame spread rate,ed hardy brasil, smoke and toxic gas emissions (ie, FST properties) and high temperature performance These properties make it be a new awareness, the application of the ACM emerge in foreign countries has been particularly stringent fire safety requirements for aircraft, subways, tunnels, mining,tory burch uk, marine, oil wells, high-rise buildings ALLIEDSIGNAL company issued a modified phenolic resin PRIMASET, it has both the general nature of phenolic flame retardant, but also the high temperature polyimide, various existing processing equipment can be made of ACM, has met the U.S. Federal Aviation Administration (FAA) regulations. NOROLDCOMPOSITES phenolic resin developed NORSOPHEN dedicated to the production of composite materials, because of its excellent FST properties. has been used in aerospace, marine, oil platforms, ferries, high-speed trains, automobiles, construction and other industries, it is a long boat that continuous use temperature 250 ℃. for pultrusion, winding (Fw), resin transfer molding (RTM), and BMC, C, and other processing molding. American Composites Technology developed TUFFCLAD composite is aldehyde formaldehyde foam core and through the pultrusion phenolic sandwich plates are full, it is lightweight,mac cosmetics discount, flame retardant, used for aircraft interior panel. OWENS - CORNING MS644 Glass has developed a phenolic pultrusion can be used for mats, from which the composite material obtained FST performance test can be said to have received FAA approval. In addition, the company has applied S-2 fiberglass fuselage and McDonnell Douglas Helicopter Bell V-22 rotor as a reinforcing material. 2. Epoxy Xiamen its epoxy composite material with adhesive power, good stability and low shrinkage, excellent performance, except for coating, sealing and structural adhesive, but can be used as composite materials used in aviation, aerospace and a variety of civil structures. In order to improve overall performance composite materials, people have done a lot of modification of epoxy resin and toughening technical work. CIBA-GEIGY company reported a method using RTM molding process and multi-functional group of epoxy resin curing agent system, the resin viscosity is low, for period (POTLIEF) long, grades for xuMY722, provided grades FIBRXEDUX Tomb of carbon fiber epoxy composite material has become the new Airbus A320 wing design using standard materials,mac cosmetics wholesale, it is lighter than metal 2O%. a 14 - -
