Standard glass melting furnaces are built with high-quality silicon fire-resistant mud. It is forbidden to use masonry kiln arches made of silica-based fire-resistant mud, all of which are configured with quartz fine powder and whose fracture-resistance is not satisfactory. When the inclined arch of the small furnace, the inserting of the flat arch, the side walls, the bottom, and the regenerator are built with silica bricks, appropriate expansion joints or related structures capable of absorbing the expansion must be installed; the application between the small furnace and the regenerator Vertical expansion joints separate. When the upper enclosure of the regenerator is built with silica bricks, the target wall of the fuel furnace or the furnace tongue of the furnace gas furnace gas regenerator enclosure, the support arch below the tongue and the upper middle partition can be Low-expansion, high-soft, zero-creep and high resistance to alkali erosion are the key advantages of the new calcium-silicate bonded brick masonry. When the upper enclosure of the regenerator is built with silica bricks, a low-expansion, low-iron, high-quality silica refractory masonry can be used to reduce the expansion of the silica brick masonry. When the bricks of different materials are used for the front end and the rear end of the tongue gas burner furnace coal gas furnace, the feet should be taken care of by adopting an independent reinforced steel structure that is individually adjusted.
The top of the tongue squad should be sealed with materials that are essentially the same as its material in order to prevent the tongue from catching fire. With soda-calcium-fired soda-calcium and borosilicate glass melting furnaces, the kiln arch (big cast) can be constructed using calcium-free bonded new silica bricks with low expansion rate, high softness, zero creep and strong resistance to alkali erosion. Charging outside the mouth of the suspension of the brick should use a coefficient of thermal expansion close to zero, excellent thermal stability and good chemical properties of high temperature fused silica brick masonry. The expansion joints of silica brick masonry are filled with quartz fibers, and it is forbidden to fill the expansion joints of silica bricks with materials composed of ceramic fibers of different phases. The domes of silica brick masonry shall be insulated with lightweight silica bricks with the same material applied on the surface, and direct insulation with clay or high-aluminum insulation materials is strictly prohibited. Marked by the "trench method", the groove should be located in the center line of the top surface of the brick, all slots around the arc should be formed, the groove should not penetrate the cold surface, the mark should be on the side of the opposite side of the pressure surface. The size of the groove is based on the ability to identify the target, and no specific provisions are made.
Blister copper (content of 99% copper) was prepared in advance as a thick plate, pure copper flakes as a cathode, with sulfuric acid (H2SO4) and copper sulfate (CuSO4) mixture as electrolyte. After power is applied, copper dissolves from the anode into copper ions (Cu) and moves to the cathode. Upon reaching the cathode, electrons are obtained and pure copper (also called electrolytic copper) precipitates at the cathode. Blister copper impurities in lively copper and zinc with copper will be dissolved as ions (Zn and Fe). Since these ions are more difficult to precipitate than copper ions, electrolysis can be avoided by appropriately adjusting the potential difference during electrolysis. Than the inactive copper impurities such as gold and silver deposition in the bottom of the cell. The copper plate so produced is called "Pure Copper Sheet (T2)" and of high quality and can be used to make electrical products. Sedimented in the bottom of the cell analogy as "anode mud", which is rich in gold and silver, is a very valuable object, remove and then processed with high economic value.
