Degradable plastic tableware production

With the continuous development of the work of "treating white" and "pushing green", the enterprises engaged in the production of bio-degradable lunch boxes have been growing, and there have been gratifying situations in which 100 schools contend and hundreds of flowers bloom. Under the premise of satisfying the use requirements and achieving the degradation index, the price has become an important factor in determining whether products have vitality. At present, the promotion of environmental protection and degradable tableware has been difficult. The main reason is price.
The reason why the price of degradable tableware is high in the market is that, apart from the high energy consumption in the production process and the resulting high costs, the high price of raw materials, especially degradation agents and compatibilizers, is a decisive factor.
It is understood that the current production of degradation aids are usually used transition metal derivatives, such as ferrocene, the price of about 80,000 yuan / ton. In the course of use, the quantity requirements are also very demanding. The standard dosage is not standardized and it is difficult to grasp. If it is used less, it will not be degraded. If not used, it will not only degrade but also make the product prolong the product life and it is difficult to meet the market requirements.
Hebei Kangsheng Industrial Co., Ltd. has newly developed a ZB-1 pro-degradant, which has a low price, and the amount needed is only 1-1.5%, and the price is about 200 yuan. This additive has good adaptability, and has good compatibility with various resins and fillers. At present, it has passed the provincial results appraisal.
ZB-1 is a compound-type pro-degradant, which has many synergistic effects on biological, light, and oxidative degradation. It can not only achieve the reliability of degradation of disposable tableware products, but also can achieve a fuzzy time control. Therefore, the application of a wide range of areas, the South wet high temperature conditions and the northern dry low temperatures can achieve good degradation purposes. In the current situation of "treating white" and "propelling green", the additive is the preferred product of the manufacturer.
The use of the additive can reduce the material cost by 30%, and can increase the filling amount of organic or inorganic fillers. According to product requirements, the filling amount of starch and inorganic filler can reach 65%-70%. ZB-1 type degradation aids are non-toxic, odorless, pure white color, and its main composite components are: photodegradation agents, biodegradation accelerators, activators, polymer compatibilizers, low molecular weight internal and external lubricants. Its performance can completely replace the expensive coupling agents, compatibilizers, dispersants, internal and external lubricants, to four generations, greatly reducing production costs. A reasonable ratio makes the agent degradable, reliable, practical, economical, and adaptable.
The ZB-1 additive is simple to use, and it is evenly mixed in a general mixer, and the twin screw extruder can be extruded and granulated. Can do the filling masterbatch, but also for the degradation of tableware special materials. Due to the fact that certain components of the additive consist of a number of monomeric copolymerized macromolecular compounds, random copolymerization is formed, the regularity of the structure is reduced, and the arrangement of the chains is loose, thereby reducing the crystallinity and improving the toughness and impact strength. The material has an elongation rate up to standard, good logistics performance and excellent processing performance. The photo-biodegradable tableware special materials for degradable starch base materials and large amounts of filled calcium powder are a good choice.
