The invention provides a method for producing a transparent clinker capable of being compounded with a colored glaze ceramic blank and relates to the technical field of building materials. The method comprises the following steps: taking quartz, potash feldspar, soda feldspar, calcite, soapstone, dolomite, barium carbonate, sodium carbonate, potassium carbonate, sodium borate and boracic acid, which are all 80-700kg and less than 100 meshes, and taking 100kg sodium chloride, sodium sulfate or fluorite, which is less than 100 meshes, as a clarifying agent; uniformly mixing the raw materials of the clinker, and then placing into a glass tank furnace for melting at 1520-1600 DEG C; and performing water-quenching, drying, crushing and screening on the melt material, thereby obtaining 20-200 mesh transparent clinker dry grains containing 50-70% of SiO2, 5-20% of Al2O3, 0-10% of CaO, 0-10% of MgO, 2-8% of K2O+Na2O, 0-8% of BaO, 0-8% of B2O3, 1-10% of clarifying agent and less than 0.5% of water. The method is used for producing the clinker; materials are selected within a preset component scope of the products; and the technology is standardized.

The invention relates to alkali-free glass fiber yarn, which is prepared from the following raw materials in percentage by weight: 20 to 40 percent of pyrophyllite, 15 to 23 percent of borocalcite, 7to 13 percent of limestone, 2 to 5 percent of feldspar, 4 to 8 percent of kaolinite, 3 to 7 percent of dickite, 2 to 6 percent of fluorite, 3 to 9 percent of borax, 1 to 3 percent of fluorite, 1 to 4percent of mirabilite, 0.2 to 1.0 percent of pure alkali, 3 to 12 percent of aluminum oxide, 2 to 6 percent of waste glass fiber yarn and 0.3 to 0.7 percent of a composite clarifying agent. The alkali-free glass fiber yarn disclosed by the invention has the characteristics of high acid-alkali resistance, high mechanical strength, high rigidity, aging resistance, high electric insulation property and high stability.

The invention discloses a purification and impurity removal method of a lotus plumule extraction solution. The purification and impurity removal method comprises the following steps: 1) taking a proper amount of lotus plumule and extracting with an ethanol water solution; filtering an extraction solution and recycling ethanol from filtrate; adding a proper amount of purified water to prepare a medicine extraction solution; 2) taking a proper amount of chitosan and preparing into a chitosan clarifying agent; 3) adding a proper amount of the chitosan clarifying agent into the medicine extractionsolution and purifying and removing impurities; filtering to obtain a clarified solution; 4) carrying out further purification on the clarified solution and separating out an alkaloid type substance;detecting the content of an effective component neferine by utilizing high performance liquid chromatography, so as to calculate the retention rate of the effective component. Under the technologicalconditions that the ratio of the medicine extraction solution of the lotus plumule is 1 to 5, the adding amount of the chitosan is 1.4g/ml, the acting temperature is 60 DEG C and the pH (Potential ofHydrogen) value is 6.0, the retention rate of the neferine is maximum. The purification and impurity removal method has the advantages of simple technology, simple steps and convenience for operation; a toxic organic solvent is not used so that the purification and impurity removal method has no dangers to environment and human bodies and no solvent residues, and is suitable for large-scale industrial production.
