Industrial Applications of Zinc borate
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Flame retardant for polymers including PVC, polyolefins, and polyurethanes; enhances flame-retardant efficiency synergistically with antimony trioxide | Blended with resin and other additives prior to extrusion or injection molding |
| Rubber Industry | Flame retardant and smoke suppressant for rubber products such as cable sheaths, conveyor belts, and seals | Incorporated into rubber compounds together with other compounding agents during internal mixing or open milling |
| Coatings Industry | Flame-retardant additive and corrosion-inhibiting pigment for fire-resistant coatings and marine antifouling coatings | Added during the grinding and dispersion stage, processed jointly with resins, solvents, and other pigments/extenders |
| Textile Industry | Flame-retardant finishing agent for post-treatment of cellulosic and synthetic fibers (e.g., cotton, polyester) | Applied via pad-dry-cure process; commonly used in combination with halogenated flame retardants |
| Electronics & Electrical Industry | Halogen-free flame-retardant filler for components such as PCB substrates, connectors, and switch housings | Used as an inorganic filler blended with epoxy or phenolic resins, followed by compression molding or injection molding |
Manufacturing Quality Control of Zinc borate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample on a white background and observe under natural light for color, state, and presence of impurities to determine if it is a white powder. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Use a laser particle size analyzer to measure the particle size distribution of the sample dispersed in liquid or gas, evaluating its fineness and uniformity. |
| Specific Surface Area | BET Nitrogen Adsorption Method | Determine the specific surface area of the material via physical nitrogen adsorption, reflecting the reactivity and dispersibility of the powder. |
| Boron Content | Titration Method (e.g., Methanol-Alkali Titration) | Dissolve the sample in acid, then titrate with sodium hydroxide standard solution in a methanol system to calculate the borate content. |
| Zinc Content | EDTA Complexometric Titration or Atomic Absorption Spectroscopy (AAS) | EDTA method: Titrate zinc ions with EDTA standard solution using chrome black T as an indicator in a buffered solution; AAS method: Digest the sample and measure zinc concentration using an atomic absorption spectrometer, offering high accuracy. |
| pH Value | pH Meter Measurement | Dissolve boron zinc in deionized water at a specified ratio, stir, allow to settle, then measure the pH of the suspension using a pH meter. |
| Moisutre Content | Drying Weight Loss Method or Karl Fischer Method | Drying method: Dry the sample at 105–110°C until constant weight is achieved, then calculate weight loss; Karl Fischer method: Suitable for trace moisture determination with higher precision. |
| Loss on Ignition (LOI) | High-Temperature Combustion Method | Ignite the sample in a high-temperature furnace (e.g., 800–1000°C) until constant weight is reached, measuring mass loss to assess crystalline water or organic matter content. |
| Impurity Elements (Fe, Pb, etc.) | Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) | After acid digestion of the sample, use ICP-OES to determine concentrations of multiple metal impurity elements with high sensitivity and simultaneous multi-element detection capability. |
| Whiteness | Whiteness Meter Measurement | Use a whiteness meter to measure the reflectance of the sample under a specified light source to evaluate its degree of whiteness, commonly used for industrial pigment-grade products. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measure mass changes of the sample under programmed temperature increase to analyze decomposition temperature and thermal weight loss behavior, assessing thermal stability. |
