Shaanxi Mobile Toilet Aromatherapy Production

The aromatherapy for mobile toilets in Shaanxi can be produced by combining general methods with the characteristics of mobile toilets. The core steps include material preparation, formula adjustment, device assembly, and adaptation optimization, as detailed below:

I. Selection of Materials and Tools

Natural plant waxes (50 grams of soy wax or beeswax), high-purity essential oils (a recommended composite formula of 15 milliliters of lemongrass/tea tree/mint, where citral and eucalyptol are combined in a 4:1 ratio to increase ammonia removal efficiency to 94.3%), slow-release regulators (5 milliliters of isopropanol or dipropylene glycol), a heat-resistant glass jar (with a capacity of 100 milliliters), and professional electronic scales and constant-temperature water baths are required. The materials must meet food-grade standards to avoid the use of industrial-grade solvents that could produce harmful substances upon volatilization.

II. Key Points in Production Process

1. Formula Adaptation: Mobile toilets have a small space (approximately 2-3 square meters), necessitating the use of a highly volatile formula (25% essential oil content + isopropanol) to ensure rapid and long-lasting fragrance coverage.
2. Temperature Control: Heat the base material in a water bath to 75±2℃ (the critical melting point of soy wax), remove from heat and cool to 55℃ before adding essential oils to prevent the volatilization of active ingredients due to high temperatures.
3. Uniform Mixing: Continuously stir at 300 revolutions per minute to ensure thorough dispersion of essential oil molecules within the base material. After adding the slow-release agent, rapidly cool to 40℃ to form a stable structure.

III. Device Assembly and Adaptation Adjustment

1. Three-Layer Slow-Release Structure: Lay activated carbon particles at the bottom to adsorb odor impurities, infuse the middle layer with the mixed base material, and cover the top with a microporous ceramic sheet to control the volatilization rate. Sealed testing indicates an effective period of 28-35 days.
2. Placement Position Optimization: Position the device 1.2-1.5 meters above the ground (e.g., on top of the toilet tank), where the air convection speed is 0.3m/s, facilitating fragrance diffusion and avoiding damp areas. Strictly prohibit installation directly below exhaust fans, as this will increase the volatilization rate by 300%, causing the fragrance to dissipate too quickly.

IV. Maintenance and Safety Specifications

1. Environmental Monitoring: According to temperature and humidity sensor data, replenish 5 milliliters of base material every 14 days when the relative humidity exceeds 65%, or it can last for 30 days in dry environments. Thoroughly replace the product when the fragrance intensity decays to 40% of its initial value.
2. Safe Operation: Ensure the operating environment has a ventilation rate of at least 30m³/h. Essential oil concentrations exceeding 20% may cause respiratory irritation. Citrus essential oils are photosensitive and should be stored away from light. Wipe the inner walls of the container with absolute ethanol monthly, and freeze the base material to -18℃ for long-term storage, which can preserve it for 6 months.

Through scientific proportioning and structural optimization, this solution can achieve the dual effects of odor control and long-lasting fragrance release in mobile toilets.
