The production of plastic


Taking a wide پلاستیک for the package promotes the growth and increase of waste and waste پلاستیکی. Now about 30% waste, urban waste پلاستیکی that gives that packaging materials خوراکی, health, etc. pharmaceutical and غیرخوراکی to work goes. Lasting a very long پلاستیک that lifes about 300 years to mature, can be in addition to environmental pollution, etc. caused the disappearance of the beauty of cities and nature can be on the other hand, recycling it, too, has problems, and the cost of economic abundance. For this reason, in the countries industrial and advanced extensive research on making پلاستیک, biodegradable is started, the پلاستیک after disposed of within a two-week conversion to CO2 and H2O disappears (di اکسید carbon and water), and therefore disappears. We are currently engaged in work and research on this type of پلاستیک. Generally, two types of پلاستیک biodegradable. a type of a mixture of پلاستیک natural and synthetic (artificial) is like the preparation of film from a mixture of starch and polyethylene, that after a while of thrown away. the destruction is decomposed and disappears. The other type پلاستیک, biodegradable خوراکی is corn starch, water, cheese and skin of the shrimp can be prepared. This پلاستیک, protein, which are also as coating on fruits, meat, and materials خوراکی or medicinal use and are also as complement food eating. For example, the coating on some pills, and capsules. خوراکی, and after intake in the body is decomposed and disappears. Our research team on both the type of پلاستیک, biodegradable purification. We are a mixture of starch and polyethylene (polymer, natural and synthetic) film, biodegradable preparation that we have, that after a while disappears. Since that this type of film, The packaging it will not be demolished, our research will notice the build sheet and خوراکی package that we have that it, too, destruction. This type of packaging is میکروب, etc. kill bacteria and enzymes present in the soil or in the vicinity of the sunlight to the weather, اکسید carbon turns and disappears. Now, our research on the production of پلاستیک of whey in concentrated is whey contains about 30% to 60% of protein is discarded to be or in the making of chips and پفک is used. Our whey protein and golden available in گلوتین (scrap left from corn after the extraction of starch) sheet, packaging خوراکی and biodegradable we've made, though, to the stage of mass production and industrial is not, but the ability to trade out of the packaging, خوراکی can be used as cladding on the chocolate. کیک, fruits, sliced, pizza and sweets. پلاستیک, خوراکی of what materials can be prepared Of all animal proteins and plant can be, and Slips خوراکی preparation. Technology, making them similar, but the manufacturing process is different. For example, the film prepared from the whey, "water,". Namely, in case absorb water, it dissolves and disappears, in the event that the movies made from Golden corn, water, getaway. We are for the productivity of the features of the two types of. they after preparing to press that we can, and so to cover the moment that it also features a unique and economically affordable. This way, our research in this field in sync with the world, goes ahead and researchers in our country have been tremendous success in this field of business which we hope the products obtained, the sooner the stage of industrial production. The difference between film and sheet packaging what is The film, a thickness of less than 500 micron, but the thickness of the sheet and layers more. Cover, سیلیفونی that about 150 to 200 micron thickness have on the fruits, food and or meat took are of the type of packaging film. Cover, biodegradable what concessions on other packing are The most important points, they are biodegradable, being, which is why countries industrial and advanced in the world, the factory, the production of پلاستیک packaging will be obliged to build a variety of پلاستیک, biodegradable has been that, though the price they are double the price پلاستیک normal, but for health reasons and ecological, the use of them is recommended. On the other side, this type of پلاستیک properties all پلاستیک the ordinary, and increases the shelf life of the substance within it. Now on some of the fruits cladding is used which has a particular fat is, and when well washed, they will not be. These cover what is to harm, no This cover, from the movie that called polishing can be prepared polishing, پلیمرهایی crime ملکولی down. This film style or polishing on the fruits would be sprinkled or fruits immersed in it). This cover, as it will not be demolished, so when washing, you will realize that you can't quite make it from the surface of the fruit that you should enjoy. So it is recommended such fruits are to be sure skin do ye; because the material is not digested and used Frequent likely مشکلاتی to create. It should be noted that this type of Cover for tools, medical, health and cosmetics, also used. The same as that previously described for the use of پلاستیک, خوراکی biodegradable, these kind of problems quite can be fix and in the meantime, you do not need the skin of some fruits that are rich in vitamins and mineral elements is taken because in case of swallowing, in addition to correction, vitamin A supplementation of protein, enter the body. Today, from what materials, typically for packaging used Substances that for the package to work, goes the phrase from metals, glass, paper and پلاستیک but now no matter can not be more vital than پلاستیک for this industry introduced. One of the applications of the vast پلاستیک. use it along with other packaging materials for the construction of the cover, is new. One of the points is noticeable in food packaging is that in the countries industrial and advanced less than 2 percent food gap between production, consumption becomes corrupt is it that in the countries to the development and progress, the cause of there failure in packaging materials for the food, the amount of rotten material to 30 to 50% looks. Maintain the quality and nutritional value in the long term, requires taking advantage of the materials, the Quality Superior and the supply of suitable conditions to minimize the amount of transformation, and food spoilage. پلاستیک such that for the food packaging should be used, what are the particulars .

In the mid-۱۹۸۰ Steven Slater (Steven C. Salter) member of the group was that the task it PBUH gene of the builder plastic from باکترى. Researchers ago than you feel that placing this enzyme in a plant can convert acetyl-coenzyme A (matter of zoning that during the conversion of sunlight into energy, it is natural in the plant formed should be) only plastic will do. In the year ۱۹۹۲ cooperation between scientists from the University of state of Michigan and the University of James Madison with this goal began. Researchers do engineering the genetics of the plant Arabidopsis Thalianan could [PHA crisp build. Two years later, the company Monsanto, for making the type more flexible PHA is a plant, the more usual meaning of corn began. Since the plastic production must be the production of food competition. researchers Your goal, it is to be used from episode one of the plant corn, which are harvested not to be found (like leaves and stems) was made. The growth of the plastic in the leaves and stems to farmers, yet the possibility cannot offer that can be combine of the question, and the fruit of the corn harvest, and with زیرورو re-farm the leaves and stems that contain plastic picked. Unlike the production of PHA and PLA to the method of fermentation, which should use the land for corn production for other purposes of competition. the growth of the PHA in the leaves and stems of corn, the possibility to the existence of God that can be corn and plastic simultaneously from a farm acquired. By the way, with the use of appropriate plants adverse conditions, like Switch grass can be from the confrontation between plastic production and other uses of land loss. What don't you see, that's just the ground that for the cultivation of corn to make this work assign. Researchers to the advancement of his sky in the field of increasing the amount of plastic in the plant and also changed the chain, and plastic in order to produce useful properties, etc. have been achieved. Although these results, when independently accessed, which are encouraging have the obtainable to both, concerning this, combining the useful and also the amount above the plastic in your plant is a problem. So far, it has been demonstrated that the chloroplasts of leaves is the best place for the production of plastics. But the chloroplasts are members of him, are that the task of their absorption of light, and this is in order that the concentration above the plastic of the photosynthesis loss and بازدهى plant to reduce him. Also, PBUH Plastic of the plant is a challenge. They researchers company Monsanto facility extraction as unit, quarter, factory, فرآورى corn in a comment). But when this unit's the paper, and the house they noticed were extracted, and the third type of plastic to the values of the transformation in a solvent requires that the result he had later in order to re-use بازیابى. This infrastructure process, in terms of size, the factory, the existing پتروشیمیایى manner), and the size of the factory Asia corn greatly increased God. It should be noted that the Do capital based and the passage of time causes that researchers on these obstacles, which overcome.

Early humans with the use of natural polymers, tool life, and the weapon name. But in the late nineteenth century was that humans could change the shape of the polymer managed to build پلاستیکها. Cellulose in the natural state, non-melting and in solvents, normal non-solvable. With نیترودار it is the first plastic business trade name Nitro cellulose emerged that significant dissolution and شکلپذیر.

In 1870, etc. of plastic called celluloid was marketed through which soften the nitrocellulose with camphor was achieved. This substance is a transparent, stiff and قالبپذیر in the preparation of objects such as artificial brush and comb, etc., fibers, etc., lacquer and ... application.
