Description
Technical field
The present invention relates to a kind of making method of glass wool, is the making method of the energy-conservation super glass wool of a kind of A level fire protection flame retarding specifically.
Background technology
Super glass wool is as a kind of fibrous novel admittance material, and it has lightweight, insulation, fire prevention, sound-absorbing, high-performance such as mothproof, anticorrosion, is widely used in chemical industry, metallurgy, light industry, electric power, oil and building trade.The material choice of super glass wool and the selection of admixtion are to being the important component part in the super glass wool production technique, and it directly affects output, quality and the production cost of super glass wool, and also there is very big influence in follow-up technology.
Summary of the invention
Goal of the invention: the objective of the invention is provides the making method of the energy-conservation super glass wool of a kind of A level fire protection flame retarding in order to overcome the deficiency of prior art.
Technical scheme: in order solving the problems of the technologies described above, to the invention provides the making method of the energy-conservation super glass wool of a kind of A level fire protection flame retarding, to it is characterized in that:
These making method concrete steps are:
(1) selects dull and stereotyped glass cullet 580-620 part, Feldspar Powder 65-75 part, soda ash 25-35 part, borax decahydrate 45-55 part, BORAX PENTAHYDRATE-99.9 MIN 30-40 part for use;
The dull and stereotyped glass cullet of wherein choosing require main component mass content accounting following: SiO2:71-73%, Al2O3:1.5%-2%, CaO:7-8%, MgO:3.5-3.8%; The summation of Na2O and K2O: 13.5%～14.5%;
The Feldspar Powder of choosing requires main component content following: SiO2:55-65%, Al2O3:18%-21%, CaO:0.2-0.8%, MgO:0.1%～0.5%; The summation of Na2O and K2O: 13%～16%;
The soda ash of choosing requires wherein, and the quality summation content of Na2O and K2O is: 56%～58%;
Main component content is following in the borax decahydrate of choosing: the summation of Na2O and K2O: 16～16.5%; B2O3:35%～38%;
Main component content is following in the BORAX PENTAHYDRATE-99.9 MIN of choosing: the summation of Na2O and K2O: 20～22%; B2O3:48%～50%;
(2), process admixtion with raw materials mix;
(3) admixtion is founded, obtained even, pure, transparent glass liquid;
(4) glass metal is imported the whizzer fibrosis and obtain glass wool.
The granular size of dull and stereotyped glass cullet described in the present invention is less than 20mmX30mm, and the granularity of Feldspar Powder is the 36-40 order.
Behind the admixtion thorough mixing, uniformity coefficient requires as follows in the step of the present invention (1):
Water-insoluble: permissible error is less than ± 0.1%;
Acid non-soluble substance: permissible error is less than ± 0.1%;
Alkalinity: permissible error is less than ± 0.6%;
Moisture: permissible error is less than ± 0.6%.
Among the present invention, found in the said step (3) and mainly contain five stages: silicate forms the stage, glass forms stage, glass metal clarification stage, glass metal homogenizing stage;
Silicate forms the stage: admixtion under 800 ℃～1000 ℃ high temperature, moisture evaporation, the component fusing, salt decomposes, and forms silicate and free silica opaque liq;
Glass forms the stage: under 1200 ℃～1400 ℃ temperature, molten silicate forms and contains the uneven transparent glass liquid of great amount of bubbles;
Silicate formed between stage and glass formation stage does not have obvious limit, and the silicate formation stage, glass forms the stage, and oneself was through beginning when not finishing as yet.
The glass metal clarification stage: under 1380 ℃～1420 ℃ temperature, glass metal viscosity reduces, and bubble overflows in the glass metal, obtains uneven no bubble glass liquid;
The glass metal homogenizing stage: each regional temperature of control molten bath, make each zone produce temperature head, rely on the natural convection of temperature difference glass metal, obtain uniform glass liquid; Wherein each regional temperature gradient of molten bath is: 2 ℃.
The homogenization process of glass metal is just own through beginning when glass forms; Yet main also carries out in the later stage in clarification stage, and it and clarifying process mix, and do not have obvious limit; Can think to clarify and carry out simultaneously, but the homogenizing end is after clarification with homogenizing.
Glass metal cooling stages: in the forehearth of glass wool kiln, glass metal is cooled to 1070 ℃～1080 ℃ or 1120 ℃～1130 ℃; Temperature is controlled to be: 1070 ℃～1080 ℃ are used to prepare yellow glass wool; Temperature is controlled to be: 1120 ℃～1130 ℃ are used to prepare the white glass cotton.Because after the glass metal homogenizing stage finishes; The temperature of glass metal is between 1300 ℃～1450 ℃; Glass metal viscosity under this temperature is too low; If feeding whizzer; The stretching easy fracture, the glass molds thickness that the back that stretches produces is too thick or too thin, thus the glass fiber diameter that causes producing is too big; After the effect of high-speed and high-temperature gas-flow, can't reach the requirement of products diameter, so can directly influence the quality of product; Through experiment showed, that in a large number when being controlled in temperature of glass liquid between 1070 ℃～1080 ℃, glass metal viscosity is optimum when the preparation yellow glass is cotton, behind whizzer, the cellucotton diameter that obtains is little, and suppleness is high.When the preparation white glass was cotton, temperature was controlled at: optimum between 1120 ℃～1130 ℃.
Among the present invention, in the said step (4), the glass metal fibrosis, step is: with temperature is the whizzer of the glass metal input high speed rotating of 1070 ℃～1080 ℃ or 1120%～1130 ℃, forms glassy membrane; Throw away the formation glass fibre through whizzer with the speed high speed rotating of 500m/s～550m/s; Then at 1800 ℃～2000 ℃; Under the high-speed and high-temperature gas-flow effect of 600m/s～650m/s, glass fibre obtains soft and thin glass wool after heating, stretching, break-in.
Beneficial effect: the making method of the energy-conservation super glass wool of A level fire protection flame retarding according to the invention has the following advantages:
Through strict control raw material, guaranteed that the super glass wool of producing meets the requirement of A level fire protection flame retarding among the present invention, adopted the proportioning raw materials among the present invention to produce simultaneously, accelerated speed of melting, practiced thrift the energy.
