To write on plastic is an unending topic. How much discussion we do

, we will always end up with the good and bad sides of it. Plastic products are now use in every field of commercial uses. Plastic pens, plastic pencils, plastic lunch boxes for children, plastic cover, plastic packaging and the list goes on and on. Though it has its bad effect on the nature, its use is still continued. As a result of which government in certain countries have to put ban on its use. But as large amount of industries are indulged in plastic making we cannot totally stop its production because latterly it would harm the earnings of the people.


Plastic is a non bio degradable material, so throwing them lavishly in the environment definitely causes harm to the nature. Many animals and plants have died to a large extent just because plastic bags are not degraded in the nature and as a result they suffocate the animals and plants which are totally dependent on nature. Moreover plastic bags cannot be recycled. Thus reusing such bags is a bad option. Plastic bags have a very versatile uses in each field. From shopping to packing things it can be used. Some of plastic bags are water resistant also. Plastic bags are available in every size and can be printed also if required by the customer. Printed plastic bags have a bit higher price than regular simple bags as the companies logos are printed on them for promotional basis. An optional to the non biodegradable plastic bags is now available and such bags are known as Sacchetti biodegradabili (biodegradable bags). Damaged caused to the planet by plastic bags will be deteriorated by use of bio degradable bags. Bags that are made from starch-based polymers can last up to 180 days.


Bio degradable bags depend on the climate and the condition of the nature. They degrade quickly because there is no fossil fuel that was used in the production of those bags. Even if we throw such bags in the nature it causes no definite change as they degrade easily. Some of the advantages of such bags are: they can be made from recyclable material, thus they can processed again. Plastic bags can be used for storing vegetables, and fruit sections. Bustine plastica (Plastic bags) that need to be vacuum-free are made of more durable plastic and are closed from all sides except for a small opening through which the air is sucked out to create a vacuum inside before sealing it. Wholesalers and online sellers of such bags are also available.

Il y a beaucoup d'options 脿 faible co没t pour garder votre facture d'茅nergie et de faire des maisons, m锚me les industries comme l'efficacit茅 茅nerg茅tique. Une de l'option majeure est d'opter pour source la plus abondante de l'茅nergie solaire pour alimenter les maisons et les industries. Au cours des derni猫res quelques ann茅es l'utilisation de l'utilisation de l'茅nergie solaire est consid茅rablement augment茅 et devrait cro卯tre rapidement dans les ann茅es 脿 venir.


Comme la plus propre et plus durable de l'茅nergie, syst猫me d'茅nergie solaire est familier avec une grande vari茅t茅 d'applications telles que les centrales solaires de puissance, les engins spatiaux, les appareils m茅nagers, calculatrice de poche et ainsi de suite.


Panneau solaire blanc est la plus propre source d'茅nergie renouvelable et il peut 锚tre utilis茅 pour r茅pondre aux besoins en 茅lectricit茅 tels que les syst猫mes d'茅clairage, de chauffage de l'eau pour des applications domestiques, commerciales et industrielles, etc. La composante essentielle dans le syst猫me d'茅nergie solaire est la cellule photovolta茂que ou solaire, par lequel l'茅nergie solaire est converti en un courant 茅lectrique sur le principe de l'effet photo茅lectrique.


Panneau solaire transparent comporte une couche de silicium de type P mis en contact avec le silicium de type N, couche de mat茅riau de type P se compose de trous pour accepter les 茅lectrons et le mat茅riau de type n a amplement les 茅lectrons, ce qui forme la jonction P-N en tant que comme composant 脿 diode.


Sous l'influence de l'茅nergie solaire, des 茅lectrons passe 脿 partir d'un mat茅riau de type N se combine avec des trous. Cela cr茅e une charge 茅lectrique de part et d'autre de la jonction p-n pour cr茅er un champ 茅lectrique.


Ce champ d茅veloppe une diff茅rence de potentiel 脿 travers la jonction. Si une charge externe est connect茅e au panneau solaire, cette diff茅rence de charge entra卯ne le courant de charge. En tant que la lumi猫re du soleil est pr茅sent sur le panneau, le courant d'entra卯nement de la charge.


Habituellement, la tension de sortie d'un panneau solaire quand il est en circuit ouvert est sup茅rieure 脿 la tension nominale. Supposons si le panneau solaire est 茅valu茅 脿 12V, il donne environ 20V dans une condition de circuit ouvert, mais si elle est connect茅e 脿 la batterie, puis il donnera 14-15V. La sortie du panneau solaire est mesur茅e en termes de watts ou de kilowatts, certains de ces 茅valuations sont 5 watts, 10 watts, 20 watts, 100 watts, etc.


Il est donc n茅cessaire de trouver l'exigence de puissance de la charge avant de s茅lectionner le panneau solaire. La consid茅ration principale du panneau solaire est la g茅n茅ration de puissance de sortie quand il est install茅 dans une position optimale.


Certains des facteurs 脿 prendre en consid茅ration pour obtenir une puissance 茅lev茅e 脿 partir de panneaux solaires sont l'orientation du panneau, la hauteur du panneau, toit, ombre, etc. Pour plus d'informations, visitez le site Total Views: 62Word Count: 470See All articles From Author
