Technology of Paper Recycling

Traditionally we use woods of trees to produce paper and at the end the paper that we have produced easily become scrap and we throw them out without considering the large amount of energy consumed to produce the paper in addition to the amount of woods that we have to get from trees. In order to get the wood, we have to cut the trees in the forest and it means that we kill a tree that has taked years and years to grow up and get to that age.

Do you know that in order to produce one ton paper out of wood, we must cut at least 15 trees? But we can produce one ton paper by recycling exactly one ton scrap paper and in this way avoid cutting 15 trees. Now consider it in the worldwide usage and the amount of trees that we can save if we recycle papers.

Of course in addition to it, by recycling the papers we can reduce the consumption of energy to 0.25 (one fourth) of energy that we need to produce paper from wood.

Also the consumption of water decreases to 0.01 (one percent) of the water used for the paper produced from wood.

We know that papers have classifications and definitely some papers are good to be recycled and used again for good quality papers. It does not mean that other papers such as carton boards and pasteboards are not good for recycling but also they can be recycled to be used as artificial paper for fruit pockets etc.

Originally this book is in English and I have translated it into Persian (Parsi or Farsi).

In this book, the author explains about paper and its appearance and then explains about different methods and standards of paper productions and superiority and deficiency of each method in comparison with each other.

It also explains that to produce different kind of paper what kind of trees should be used and the what the ingredients of paper producing process is?

It offers all scientific calculations about the paper industries and logic of paper production.

After describing all different type of papers and circumstance to produce them, it explains about recycling technologies and conditions to prepare all different type of papers.

I just wanted to have a short description of this book.

If you like to have this book in English, its name is "Technology of Paper Recycling".

Microprocessor of GT26CW Locomotives of Iran

One of my books.
Railways of Iran operates EMD (Electro Motive Devision) locomotives type GT26CW and GT26CW-2, G22 and some G12 locomotives as well as GE locomotives.

The huge percent of Iran railways Locomotives are GT26CW and due to the old technology the these locomotives posses, it was becoming harder to supply the spare parts. Therefore Iran railway had several option to go ahead and between those options, Iran Railway management decided to modify old and out of services locomotives by PLC system that we as a common mistake call it "microprocessor".

The benefits to use microprocessor on locomotive are: 

1. Up to date technology
2. Available spare parts
3. Better performance
4. Lower price rather than old system
5. Easy maintenance

This new system replaces 11 module cards and several relays of GT26CW-2 locomotive and several parts and contactors and relays from GT26CW locomotives.

In addition to eliminating those parts, the maintenance cost of locomotive reduces in comparison with old type of locomotives. Of course it depends on quality of utilization.

Iran railway modified 62 locomotive by microprocessor system. I was involved in this project and had some responsibilities.

when we did the first locomotive modification, employees of Iran railways showed a kind of resist against this new generation of locomotive because they had experienced very bad memory with Alstom locomotives which were made at 2002.

I had to teach locomotive drivers to how operate units as locomotive engineers, engineers of running shops to supervising the process of maintenance repairs and fault troubleshooting.

also I had to work with the team of railway engineers to teach and train the railway technicians to repair locomotive as persons with hands on the job.

We proposed an offer to Iran railways about writing a book to be used as global reference for engineers and technicians and workers. Iran railway management accepted the proposal.

i wrote this book which is a combination of microprocessor manufacturer manual and my experience during teaching and taking care of maintenance of these locomotives.

The name of this book is "Microprocessor of GT26CW Locomotives and Its Maintenance". 

This book is being used as a technical reference in Iran railways.

I had some several meetings to introduce this book to managers of Iran railways in other provinces than Tehran. Nowadays it is being used as reference for microprocessor repair on board and microprocessor parts repair manual (maintenance instruction)

Some chapters of this book are;

1. Microprocessor parts introduction
2. How to operate this system
3. How to maintenance system

This book is in Farsi. If a visitor is interested in purchasing this book can visit our official website at http://www.Vista SPG.com and under the page "Order Online" or "Products" do the shopping.

Plastic Recycling Technology and Plastic Grinding Machine Design

One of my books.
At 1996 after my professor advise about searching for a project and working on it to be useful for people, I searched about plastic and decided to concentrate on this issue.
Plastics are good replacement for wood, glass, ceramic and metal. In addition to cheap prices rather than other materials, also can be retrieved easily from recycled materials and also are very easy to shape for different uses.
Plastics are derived of petrol and their main base is ethylene (C2H4).
Petroleum sources in the world are very limited and converting petroleum into plastic for human daily uses is not logic.
On the other hand, Plastics cannot be disintegrated normally in the nature. Therefore the best way to prevent nature infect and also saving petroleum for next generations is the recycling.
But plastics are divided in two different categories and surely method of recycling per each category will be different.
As I told you please are divided into 2 categories: Thermoplast (Thermo Plast) and Thermoset (Thermo Set).
Each category also has its sub-categories.
As a short description for Thermoplast palstis would say thermoplasts are a kind of plastics that liquefy by getting heat and can get the shape of container when loses the heat. This type of plastic can be heated times and times and also can be grind and get reused in other applications.
As a short description for Thermoset palstics would say thermoset plastics are a kind of plastics that cannot be reheated after the first heat up and getting shape. This category has very high rigidity and resistance against stresses, heat, chemical solvents and also have very high electrical resistance.  
Every material has its own usage for example you cannot use polyester instead of poly acrylic. Each plastic material has its own characteristics and specification that makes it appropriate for an individual application.
Recycling Technology is applicable about the Thermoplast plastics and for Thermoset plastics different method must be used.
Waste plastics must be collected from home made plastics or industrial wastes. At any circumstances those plastics must be de-germ and other actions must be done on it util the waste plastics gets converted into granule. This produced granule can be used to re-produce plastic materials and products.
In this book I have explained about plastics and each categories' subset plastics and each subset's usage.
Then I have explained the method of reducing parasites and washing procedure, separation of different type of composites and producing granule.
In one of the chapters of book, I have shown the design calculation of grinding machine of plastic.
This book was published at 1999 and received approval of Department of Environment of Iran.
I got the international reward for this action and at the same time certificate of invention.
This book needs to be updated because since 1999 it has not been reviewed.

Let me know your opinion about my writings

Dear visitors
Hello
I will translate my published articles into English and will put in my blog.
Of course it will take time to do it but  I am serious in doing it.
I have some athletic-scientific articles and 2 scientific articles that have been published in Iran. Those athletic-scientific articles have been published in Iranian magazines but those mechanics papers have been published at internal magazine of Takestan Azad University.
I will give you short description of my books. Those books are also in Farsi (Persian) but if you are Persian and are interested in getting it, please do not hesitate to contact me at any moment.
I eagerly look forward to get your feedback about the articles. It will help me in improving my knowledge.
