Abstract
Flat glass dihasilkan dari campuran silika dioksida dalam
bentuk materi bening dan transparan. Pabrik flat glass ini akan
didirikan di daerah Cilegon, Banten. Pabrik ini menggunakan bahan
baku fly ash yang mengandung silika sebesar 75% dengan proses float.
Pembuatan pabrik flat glass dari fly ash dengan proses float
melalui 6 tahap. Tahap pertama yaitu persiapan bahan baku. Tahap
kedua yaitu proses pencampuran bahan baku. Tahap ketiga yaitu tahap
peleburan dimana terjadi perubahan sifat fisik maupun sifat kimia pada
temperatur berkisar 1450 oC. Tahap keempat yaitu proses float yang
diperoleh dengan cara mengambangkan kaca cair diatas timah cair
untuk memperoleh kerataan kaca yang datar. Tahap kelima yaitu proses
pendinginan kaca yang dihasilkan dari proses float. Tahap terakhir
yaitu proses pemotongan dan pengepakan.
Pabrik flat glass bekerja secara kontinyu dan beroperasi
selama 330 hari/tahun dengan kapasitas produksi 26.000 ton/tahun. Fly
ash yang dibutuhkan yaitu sebesar 25.412 ton/tahun dengan bahan baku
pendukung soda ash dan lime stone. Kebutuhan utilitas adalah air
umpan boiler, air sanitasi dan air proses masing-masing sebesar
285.214 m3/tahun, 7.345 m3/tahun dan 1.164,57 m3/tahun. Limbah yang
dihasilkan dari industri ini yaitu fly ash sisa, cullet atau potongan kaca
dan gas hasil pembakaran. ========== Flat glass produced from the mixture of silica dioxide in
the form of material clear and transparent. Factory flat glass this
will established in the Cilegon, Banten. This factory uses raw
materials fly ash with silica content of 75% with the process of
float.
Manufacture of flat glass factory from fly ash with the
float through 6 stages. The first stage factory is preparation raw
material. The second stage is the process of mixing raw
materials. The third stage is the stage of smelting which changes
the physical properties and chemical properties at temperatures
ranging from 1450 OC. The fourth stage process namely float
obtained by means floated molten glass above molten tin lead to
acquire flatness flat glass. The fifth stage is the process of cooling
the glass out of the process of formation. The last stage is the
process of cutting and packing.
Flat glass factory work continuously and operates during
330 days/year with a production capacity of 26.000 tons/year. Fly
ash is needed of 25.412 tons/year with supporting raw materials
of soda ash and lime stone. The needs of utility boiler feed water,
process water and sanitation water each of 285.214 m3/year,
7.345 m3/year dan 1.164,57 m3/year. Waste resulting from
industry is fly ash left over, cullet or pieces of glass and gas a
result of burning.
