Production with a diameter of 5 ~ 10 m or larger short basalt fiber required for selection of basalt ore should have under the table shown in the composition range: * * * in addition, one should also meet the Department of Shimonoseki between Chemical Group production of basalt fiber with basalt ore: 1.7 > Mc > 3.2. = Mc (SiO: 2 + Al: 2 O: 3) / (Fe: 2 O: 3 + FeO + TiO: 2 + CaO + MgO + K + Na O: 2: 2: 7.2, O) M k > 4.3, kappa = M (SiO: 2 + Al: 2 O: 3) / (CaO + MgO) in production of basalt fiber used in ore S IO: 2 and Al: 2 O: 3. The overall content should be in 54 ~ 80%. In 2 the production of basalt fiber used in ore SiO down, should be in 42 ~ 60%. Table composition provided above is also suitable for insulation materials used in making building basalt ore matching, but to reduce the melting temperature of basalt ore and reducing the cost of production of fiber, can be difficult to let the content of oxide ore to improve, Fe: 2 O: 3 and FeO content of up to 16%, CaO the content of Na was 12%, down 2, down O and K content of up to 6% 2 O. For the preparation of thermal insulation materials, dust filtering equipment used in temperature and 600-700 material in fire protection system at a temperature below 1000 DEG C for one-time use need to select the components shown in the table below: * * * basalt ore production of these products should be required of basalt fiber with a sufficiently high strength and high temperature performance. So the content of basalt ore in SiO: 2 and Al: 2 O: 3 of these basic oxides should be in 65 ~ 80%. Making rural domestic wastewater, petroleum and chemical industry city drainage and soil improvement and irrigation to filter and manufacturing building in fiber reinforced concrete and asphalt concrete surface strengthening of road construction materials are selected to ensure the production needs of the fiber has high chemical stability of basalt ore. Basalt ore compositions suitable for making high chemical stability basalt fiber products are listed in the following table. * * * *.
【技术实现步骤摘要】
本专利技术涉及由玄武岩矿石熔融液制取短纤维的生产工艺和所使用的相关生产装置。玄武岩是处于火山岩浆产地的矿石,大自然使其生来具有很高的化学稳定性和热稳定性。玄武岩矿石是大自然提供的单组分原料,它的熔炼精选及均匀化是火山岩活动的结果。由玄武岩矿石制成的纤维(后简称玄武岩纤维)生来具有很高的初始强度,并耐多种活性介质的作用、而且热稳定性高、寿命长。玄武岩纤维在能源、冶金、机械制造、化工、农业、建材业等领域有着十分广阔的应用前景。在声热绝缘材料、耐高温且化学稳定性高的过滤器材、电绝缘材料、复合材料及其制品的制造中玄武岩纤维的应用尤其广泛。玄武岩纤维在强度、化学稳定性、使用温度及吸湿性方面的参数优于玻璃纤维,它还是有致癌作用的石棉纤维材料的替代品。制造玄武岩纤维的原料几乎不受限制,其原料产地广泛且很多矿源易于开采。然而玄武岩纤维的广泛应用也一直受到其相对复杂的生产工艺的制约。所以研究与完善玄武岩纤维的制造工艺具有极大的现实意义。无论是制造声热绝缘材料、清理排除烟气中粉尘颗粒的过滤器和污水清理用的过滤器,还是制造无土水栽培材料和水土改良及土地灌溉所需要的材料都需要大量的玄武岩短纤维。表1中给出了玄武岩短纤维的分类以及玄武岩短纤维材料的应用领域。表1. 本专利技术提供了制造玄武岩短纤维的较为完善的方法和设备。其中玄武岩短纤维的生产工艺方法中包含以下一些要点1.矿物原料选择,即生产玄武岩短纤维的玄武岩矿石所包含的各种化学成分的含量应在表2所给出的范围之内。表2. 适于制作玄武岩短纤维的玄武岩矿石中的三种硅酸盐成分比例由说明书附附图说明图1的三角图给出。此外,为制作玄 ...
