Detailed Description
As shown in fig. 1, the method for discriminating the fiber forming ability of basalt ore provided in this embodiment includes the following steps:
Step 1: the method comprises the steps of obtaining the mineral and the content of basalt ore to be detected by adopting a light slice identification analysis method, wherein the content of feldspar and pyroxene is more than 75%, the quartz content is less than 10%, the content of metal mineral is less than 5%, and the basalt ore without olivine is a primary screening qualified ore.
Step 2: adopting CIPW Norm method to obtain main element oxide content of the primary screened qualified ore in step 1; wherein the main element oxide comprises ：SiO2、TiO2、Al2O3、Fe2O3、FeO、MgO、CaO、Na2O、K2O.
Step 3: and (3) calculating an ore viscosity coefficient and a relation coefficient according to the content of the main element oxide obtained in the step (2), and judging the preliminary fiber forming capability of the basalt ore according to the calculated viscosity coefficient and relation coefficient.
The relation coefficient，、、、、、、、、The relation coefficient of the main element oxides determines the wire-out characteristics of the ore melt solution for producing basalt fibers, which are respectively calculated for the content of SiO2、Al2O3、Fe2O3、FeO、CaO、MgO、K2O、Na2O、TiO2 by the CIPW Norm method in the step 2.
The viscosity coefficient，、、、、、、、The content of SiO 2、Al2O3、Fe2O3、FeO、CaO、MgO、K2O、Na2 O calculated by the CIPW Norm method in the step 2 is that the viscosity coefficient is the number of cation atoms of the oxide for increasing the melt viscosity and the oxide for reducing the melt viscosity in the element, which is not less than 1.5.
In the embodiment, an average value M of a relation coefficient and a viscosity coefficient is used as a judging index, wherein basalt ore with the average value M of 2.1-3.08 has fiber forming capability, namely。
Step 4: further, the basalt ore capable of forming fibers is evaluated, the acidity coefficient and the Fe ratio coefficient are calculated through the main element oxide content calculated in the step 2 of the basalt ore with the primary fiber forming capability in the step 3, and the fiber forming capability of the basalt ore is further evaluated through the acidity coefficient and the Fe ratio coefficient.
Specifically, the acidity coefficient，、、、The contents of SiO 2、Al2O3, caO and MgO calculated by the CIPW Norm method in the step 2 are respectively.
The acidity coefficient has a larger influence on the melting and wire drawing temperatures of basalt, so that the chemical stability of continuous basalt fibers is finally influenced, and the higher the acidity coefficient is, the higher the ore melting temperature and the viscosity of a melt are, the higher the chemical stability of the manufactured fibers is.
The Fe ratio coefficient，、The contents of FeO and Fe 2O3 calculated by CIPW Norm method in step 2 are respectively calculated.
The absolute percentage of the Fe ratio has the greatest influence on the thermal stability and strength of the fiber, and firstly, the thermal stability of the fiber is influenced, feO is converted into Fe 2O3 due to the oxidation process in the process of heating the fiber to the temperature of 700 ℃, so that the fiber obtains the special color of ferric oxide, and the fiber is fragile and easy to break due to the formation of large-particle magnesite crystals during crystallization of the fiber.
To verify the effectiveness of the method of this example, 37 different basalt materials were selected to compare the log η values of the viscosities of the melts, and the log η values of the viscosities were calculated relatively complex, but the values could well evaluate the fiber forming ability of basalt. As shown in fig. 2, the average value M of the relationship coefficient and the viscosity coefficient calculated in this example is highly coincident with the result of the viscosity log η, thereby proving the effectiveness of this example.
The methods of this example were used to evaluate whether sample 1, sample 2, and sample 3 could be used as basalt wiring fibers.
As shown in table 1, the detected main element oxides of sample 1, sample 2, and sample 3 and the test results thereof.
