Problems solved by technology
At present, the feeding method of small kilns is mostly manual feeding. Due to the large number of kilns, workers often add too much raw material at one time, causing the glass liquid level to rise rapidly, and due to the accumulation of materials, the temperature control is uneven, making the glass liquid These factors will affect the drawing process, increase the work difficulty of the drawing front desk staff, and reduce the drawing efficiency. At the same time, the quality of the produced glass wool is unstable, such as density, thermal conductivity, sound absorption coefficient, flame resistance, etc. Unable to meet user needs

Embodiment 1
[0040] Before the raw materials are put into the kiln, the raw materials are washed and crushed with a stone crusher respectively, then ball milled with a ball mill, sieved with a sieve, and then mixed according to the required weight ratio. Silicate formation stage, glass formation stage, glass liquid clarification stage and glass liquid homogenization stage, finally generate pure and transparent glass liquid that meets the molding requirements.
[0041] A production method of flocculent glass wool, which comprises the steps:
[0042] (1) The raw materials are put into the kiln in equal amounts for several times and melted into a glass solution;
[0043] The raw materials include the following components by mass: 470 parts of quartz sand, 116 parts of feldspar powder, 100 parts of dolomite powder, 29 parts of calcite powder, 7.8 parts of fluorite powder, 143 parts of soda ash, 13 parts of sodium nitrate, 2.6 parts of potassium carbonate , 57 parts of zero water borax.

Abstract
The invention discloses a production method of flocculated glass wool, which comprises the following steps: (1) raw materials are put into a kiln in equal amounts several times and melted into a glass solution; The leaked material is heated by an electric leakage plate in the leaking area of the kiln, and the leaked glass solution is a fine glass filament; (3) the glass filament is blown by gas and air at the head of the kiln to form an appearance that is Glass wool with cross floc structure. In the present invention, by rationally controlling the single feeding amount and feeding timing, combined with the raw material ratio of the present invention, on the one hand, it can control the temperature stability in the kiln, and the temperature change in the furnace does not exceed 5°C, which greatly improves the heat exchange efficiency of the kiln. Reduce energy consumption and reduce production costs; on the other hand, the temperature of the molten glass is uniform and the glass liquid is clear and transparent. On the basis of ensuring the drawing yield and fiber qualified rate, the quality of the produced glass wool is stable.
Description
【Technical field】 [0001] The invention relates to the technical field of glass wool production, in particular to a production method of flocculent glass wool. 【Background technique】 [0002] Glass wool is an inorganic fiber. Because of its good molding, low bulk density, low thermal conductivity, good thermal insulation, sound absorption, corrosion resistance and good chemical properties, it is widely used in oil pipelines and natural pipelines. gas field. [0003] At present, the main equipment for melting glass blocks into glass solution in the production of glass wool felt by the flame method is a small kiln. The heat exchange efficiency, energy consumption and the quality of the molten glass have a great influence. The uniform temperature of the molten glass and the clarification of the molten glass are favorable measures to ensure the wire drawing yield and fiber qualification rate and reduce the production cost. At present, the feeding method of small kilns mostly ad...
