Application background and overview of calcium tetraborate
The chemical formula of calcium tetraborate is CaB4O7, which can be decomposed into diborate by a large amount of water. Calcium tetraborate can be obtained by melting a mixture of calcium oxide and excess boric acid with sodium chloride and potassium chloride.
Applications of calcium tetraborate
Calcium tetraborate is used as a melting agent, preservative, astringent and fire retardant paint for heavy metal smelting. Examples of its application are as follows:
1) Prepare a wiring harness for steam and electrical components with strong comprehensive performance.
It is composed according to the weight parts of the following raw materials: 9 parts of natural rubber 86-10 dimethyl sulfoxide, 34-59 parts of polyvinyl chloride, 1-5 parts of sodium dodecyl benzene sulfonate, methyl trisulfoxide 8-15 parts of ethoxysilane, 6-10 parts of dibutyl phthalate, 7-12 parts of N-cyclohexyl-N-phenyl-p-phenylenediamine, 3-8 parts of hydroxyethyl hexahydros-triazine parts, 5-9 parts of methyl tert-butyl ether, 3-8 parts of magnesium hydroxide, 11-15 parts of polylactic acid, 2-6 parts of barium myristate, 1-4 parts of barium stearate, 1 part of barium laurate -5 parts, 2-6 parts of calcium tetraborate, 2-5 parts of zinc undecenoate, 8-14 parts of silica powder, 3-7 parts of silica, 3-6 parts of urea phosphate, 2-7 parts of copper rosinate 7-11 parts of high-temperature activated bamboo charcoal powder, 1-4 parts of organic solvent, 1-4 parts of antioxidant, 1-3 parts of sulfur, and 13-20 parts of paraffin oil. The invention has good wear resistance, good hydrolysis resistance and chemical resistance, good insulation, acid and alkali resistance, picolinium chromium pressure resistance and peeling resistance, and stable physical and chemical properties.
2) Prepare a low porosity coating for steel bar anti-corrosion.
The raw materials include the following components: 45-70 parts of feldspar powder, 15-30 parts of borax, 10-20 parts of calcium tetraborate, 5-15 parts of fluorspar, 4-8 parts of clay, 1.0-10 parts of adhesive, Thickener 1.0-1.5 parts. The invention also discloses the coating method of the above-mentioned low porosity coating for steel bar anti-corrosion, which includes the following steps: 1) dry mixing; 2) wet mixing; 3) pretreatment; 4) coating; 5) baking ; 6) Sintering; 7) Cooling at room temperature. The invention has outstanding corrosion resistance, extremely high toughness and high self-durability.
3) Prepare a moisture-proof and antibacterial sheath material for wire harnesses.
It is made of the following raw materials by weight: nylon 66-45-60, polylactic acid 15-25, isocyanate propyltriethoxysilane 3-6, copper rosinate 4-7, barium myristate 2- 3. Barium laurate 1-2, spherical calcium chloride dihydrate 2-4, adamantium 5-10, hydroxyethyl hexahydrostriazine 3-5, dicyclohexyl phthalate 10-15, tetrahydrofuran Calcium borate 5-7, high temperature activated bamboo charcoal powder 7-11, seabed placer 12-17, zinc undecenoate 2-4, ricinoleic acid amide 4-6. The water machine wire harness sheath material produced by the invention has excellent moisture-proof performance and antibacterial performance, can effectively inhibit the growth of bacteria and mold, can work in a humid environment for a long time, and is not easy to cause damage and rot of the sheath.
