Basic Theory of Fireworks and Firecrackers

Chemical Explosives is an assembly consisting of solid material or liquid or mixture of both that when subjected to the action (such as impact, heat, and friction) can lead to high-speed reaction accompanied by the formation of gases and heat and pressure effects are very high. Chemical explosives can be divided into two types, namely low explosive (low yield) and high explosive (high explosive power).

Low explosive explosives are explosives that have a low detonation velocity (velocity of detonation) between 400 and 800 meters per second. While the high explosive detonation velocity explosive has between 1,000 and 8500 meters per second. Low explosive explosives are often called propellant (booster) that is widely used as the bullets and rockets

Among low explosives are explosive known gunpowder (black powder or gun powder) and smokeless powder. For some communities in Indonesia, gunpowder is widely used as a maker of fireworks, including firecrackers and bombs rock fish. Gunpowder is the oldest type of explosives were found by the Chinese in the 9th century. Aside from being a maker of firecrackers and fireworks, gunpowder now widely used as propellants and rocket shells, rocket-signals, fireworks, explosive fuse, and fuse explosive wait.

Composition of Firecrackers

Some compositions are known to manufacture black powder, among others:

mixture of potassium nitrate (KNO3), charcoal, and sulfur;

mixture of sodium nitrate (NaNO3), charcoal, and sulfur;

mixture of potassium nitrate and charcoal (without sulfur); and

pyrodex, a mixture of potassium nitrate, potassium perchlorate (KClO4), charcoal, sulfur, cyanoguanidin, sodium benzoate, and dextrin.

However, firecracker maker in Indonesia itself, not much use materials above, only a few such as Potassium, and sodium only.

i thought this is enough for now, for fire crackers, about fireworks is waiting for the next post.

Tahun Baru, Tahun 2011

yo.o.o.o.o...happy new year fo all.....
how about you all, do you pepople anjoy last year anfs gonna make a resolution for next ?
Ya, me to...

do you know, what so indentic with new year celebration ?
Is that roasting s turkey? ,owh..not, that is when we are thanks giving

I gues, this is the best answer

yes.....that is fire works party..

you know about fire works, i'll tell u about fire works, from first time it been found

Founded in China around 9-century, by accident, a chef mixing three ingredient of black powder or the potassium nitrate, sulfur, and charcoal, which comes from his kitchen. It turned out that the third mixture is flammable materials.

If the three ingredients are incorporated into a piece of bamboo that is then burned in the axis that will explode and make a loud explosion, they believed to expel evil spirits. In its development, this type of firecracker is also believed to be used in the celebration of marriage, the war victory, lunar eclipse events, and religious ceremonies.

Just at the time of the Song dynasty built fireworks factory that later became the basis of the manufacture of fireworks because of more emphasis on colors and shapes borax fire in the sky( a lot of sparkle with diferent colours ) until finally distinguished. The tradition of fireworks then spread to all corners of the world.

In Indonesia itself ou own tradition of fireworks brought by the Chinese. One observer of history Betawi, Alwi Shahab believe that marriage tradition Betawi people who use fireworks to enliven the atmosphere to mimic the Chinese people who live around them.

The spreading of fireworks now is getting larger, and, no one didn't know about it, except junggle pople ( ...^_^LOL )

I guess, that sit from me, for the next, Fire works chapter two
hope you like it.

Be careful in adulthood


Adulthood .... it's not an ending from seeking more knowledge, but a beginning of a new achievement.
don't think, as adults want to get married and then had a family and worked as usual. according to research by the age of 20 upwards will gradually experience cognitive decline. see, whether brother or your father, semahir you play games or playstation.

The study was conducted on 2,000 men and women for seven years. Respondents aged 18 to 60 were asked to solve a visual puzzle, remembering the words and observe patterns in the writing and symbols.

Similar tests are often used to diagnose mental disabilities including dementia.

Research by the University of Virginia found that nine of the 12 tests of the average experience the highest performance at the age of 22 years.
The first age is a performance decrease on 27 for three tests involving the ability to understand, the speed of thinking and visual observation. Memories showed a decrease in the average age of 37 years. Other tests showed the worst in 42 years of age.

But in research published in the journal Neurobiology Of Aging, found that the ability of vocabulary or general information continue to rise until the age of 60 years.

Age 27 years old has a negative connotation. At that age many musicians die, a kind of Jimi Hendrix, Jim Morrison, Brian Jones, Janis Joplin and Kurt Cobain.

Kertas
Dari Wikipedia bahasa Indonesia, ensiklopedia bebas


Selembar kertas
Kertas adalah bahan yang tipis dan rata, yang dihasilkan dengan kompresi serat yang berasal dari pulp. Serat yang digunakan biasanya adalah alami, dan mengandung selulosa dan hemiselulosa.
Kertas dikenal sebagai media utama untuk menulis, mencetak serta melukis dan banyak kegunaan lain yang dapat dilakukan dengan kertas misalnya kertas pembersih (tissue) yang digunakan untuk hidangan, kebersihan ataupun toilet.
Adanya kertas merupakan revolusi baru dalam dunia tulis menulis yang menyumbangkan arti besar dalam peradaban dunia. Sebelum ditemukan kertas, bangsa-bangsa dahulu menggunakan tablet dari tanah lempung yang dibakar. Hal ini bisa dijumpai dari peradaban bangsa Sumeria, Prasasti dari batu, kayu, bambu, kulit atau tulang binatang, sutra, bahkan daun lontar yang dirangkai seperti dijumpai pada naskah naskah Nusantara beberapa abad lampau.
Sejarah
Peradaban Mesir Kuno menyumbangkan papirus sebagai media tulis menulis. Penggunaan papirus sebagai media tulis menulis ini digunakan pada peradaban Mesir Kuno pada masa wangsa firaun kemudian menyebar ke seluruh Timur Tengah sampai Romawi di Laut Tengah dan menyebar ke seantero Eropa, meskipun penggunaan papirus masih dirasakan sangat mahal. Dari kata papirus (papyrus) itulah dikenal sebagai paper dalam bahasa Inggris, papier dalam bahasa Belanda, bahasa Jerman, bahasa Perancis misalnya atau papel dalam bahasa Spanyol yang berarti kertas.
Tercatat dalam sejarah adalah peradaban Cina yang menyumbangkan kertas bagi Dunia. Adalah Tsai Lun yang menemukan kertas dari bahan bambu yang mudah didapat di seantero China pada tahun 101 Masehi. Penemuan ini akhirnya menyebar ke Jepang dan Korea seiring menyebarnya bangsa-bangsa China ke timur dan berkembangnya peradaban di kawasan itu meskipun pada awalnya cara pembuatan kertas merupakan hal yang sangat rahasia.
Pada akhirnya, teknik pembuatan kertas tersebut jatuh ketangan orang-orang Arab pada masa Abbasiyah terutama setelah kalahnya pasukan Dinasti Tang dalam Pertempuran Sungai Talas pada tahun 751 Masehi dimana para tawanan-tawanan perang mengajarkan cara pembuatan kertas kepada orang-orang Arab sehingga pada zaman Abbasiyah, muncullah pusat-pusat industri kertas baik di Baghdad maupun Samarkand dan kota-kota industri lainnya, kemudian menyebar ke Italia dan India lalu Eropa khususnya setelah Perang Salib dan jatuhnya Grenada dari bangsa Moor ke tangan orang-orang Spanyol serta ke seluruh dunia.
Pembuatan kertas
Artikel utama untuk bagian ini adalah: Teknik pembuatan kertas
Di tahun 1799, seorang Prancis bernama Nicholas Louis Robert menemukan proses untuk membuat lembaran-lembaran kertas dalam satu wire screen yang bergerak, dengan melalui perbaikan-perbaikan alat ini kini dikenal sebagai mesin Fourdrinier. Penemuan mesin silinder oleh John Dickinson di tahun 1809 telah menyebabkan meningkatnya penggunaan mesin Fourdrinier dalam pembuatan kertas-kertas tipis. Tahun 1826, steam cylinder untuk pertama kalinya digunakan dalam pengeringan dan pada tahun 1927 Amerika Serikat mulai menggunakan mesin Fourdrinier.
Peningkatan produksi oleh mesin Fourdrinier dan mesin silinder telah menyebabkan meningkatnya kebutuhan bahan baku kain bekas yang makin lama makin berkurang. Tahun 1814, Friedrich Gottlob Keller menemukan proses mekanik pembuatan pulp dari kayu, tapi kualitas kertas yang dihasilkan masih rendah. Sekitar tahun 1853-1854, Charles Watt dan Hugh Burgess mengembangkan pembuatan kertas dengan menggunakan proses soda. Tahun 1857, seorang kimiawan dari Amerika bernama Benjamin Chew Tilghman mendapatkan British Patent untuk proses sulfit. Pulp yang dihasilkan dari proses sulfit ini bagus dan siap diputihkan. Proses kraft dihasilkan dari eksperimen dasar oleh Carl Dahl pada tahun 1884 di Danzig. Proses ini biasa disebut proses sulfat, karena Na2SO4 digunakan sebagai make-up kimia untuk sisa larutan pemasak.
