Corn crops accounted for 36% of world output. Besides the role of food, natural resources, renewable, versatile and self-destructive are many other commercial applications. In the role of raw material, corn is replacing oil in industrial applications, from plastic containers to clean-burning alcohol. The goal of the current production is geared to produce 5 billion gallons of corn ethanol per year. The composition of corn can be found in hundreds of products ranging from food, drugs, cosmetics, detergents bobov dol and glue and shoe polish. For example, corn oil is used in moisturizing creams and toothpaste. Core corn syrup used as a carrier in cosmetics. bobov dol
Development of a new polymer septic is a top priority of the chemical industry green materials standpoint of environmental conservation. Polymer septic corn has some remarkable advantages compared to other synthetic materials. The polymer derived from corn starch (a component of corn) or other carbohydrate made from renewable sources bobov dol has been used in the production of packaging materials, plastic woven fabric with high quality materials and Biomedical. For example MEM biology, biological microchips, biofilms, etc. ... To achieve such accomplishments, fresh technologies based on the basic chemical materials in the muscles from many companies around world investment and deployment.
Starch, the main ingredient in corn, is a poly-saccaride formed bobov dol from simple sugars glucose group with 1-4 carbon bonds to form long chain containing simple sugars bobov dol glucose units 500-2000. There are two major types of polymer in the amylo and amylopectin starch. This amylo Both are flexible and digestible.
When the starch content in the polymer increases, the septic and it also increases the persistent component will decrease. The biological degradation of starch-based polymer as a result of hydrolysis enzymes attack the glycoside links between these groups to reduce the path length of the polymer and release circuit bobov dol units of simple sugars into the environment.
The starch-based polymer septic been investigated for potential applications in biomedicine. For example, new processing techniques and reinforced bobov dol with different bobov dol filler materials has led to the development of material systems with comparable mechanical properties like bone. The polymer is suitable for bone replacement implants, as bone glue, drug delivery systems, implants and patches.
Plastics known as thermoplastic starch when it has starch content (amylo) more than 70%. When this resin is plasticized by the solvent plasticized concrete, they create thermoplastic materials featuring bobov dol good and potentially septic. High hydrophilic nature of plastic carry high starch content can be overcome bobov dol by the addition of stop mix with water affinity of starch composition bobov dol or through chemical modification, such as acetylation, esterified, ethers chemistry. The starch-based polymer plasticizers commonly, reduced levels or structure combined with other high-performance polymers bobov dol such as aliphatic polyester, polyvinyl alcohol to bring the physical bobov dol properties useful for packaging bobov dol applications.
The combination of synthetic aliphatic polyester may septic starch is often used to produce high-quality cardboard and films for packaging. Approximately 50 percent of the polyester synthesis (which costs about $ 4.00 / kg) can be replaced with natural polymers, such as starch (about $ 1.50 / kg). In addition, the polyester can be modified bobov dol by incorporating additional functional groups (eg, hydroxy, amino, carbonyl, etc.) have the ability to respond to natural polymer starch.
Some packaging bobov dol products bobov dol made of plastics derived from starch is currently available bobov dol on the market. These include thin film products (for example, shopping bags, bread bags, bait bags, packaging films used for the oven, and lining materials for the toilet bowl can be removed) and membrane Government straw compost. A similar commercial product brand is "BioBag," bobov dol made from plastic Novamont (invented in Italy) between 1994 Essentially, Packaging BioBag products are made from cornstarch combined with full plastics or biodegradable polylactic acid.
Other products are produced from starch-based foam. A famous example bobov dol is the balls melt in the bud
