The filling operations in the daily chemical industry face unique engineering challenges. From lightweight, easily dispersible shampoos and thick, viscous creams to chemically corrosive disinfectants, the characteristics of these products place stringent demands on the filling process. Traditional general-purpose filling equipment often falls short. Therefore, targeted specialized filling solutions are needed to ensure production efficiency and product quality.

Accurate filling of high foaming liquids is a primary technical challenge.

Products such as shampoos and shower gels are prone to foaming during the filling process, leading to insufficient filling volume and packaging contamination. The solution lies in using anti-foaming filling valve technology. This specially designed filling valve optimizes the flow channel curve to achieve laminar flow of liquid along the container wall, avoiding violent impacts that generate foam. Simultaneously, the filling valve is equipped with an intelligent back-suction function, automatically drawing back a small amount of liquid at the moment of filling completion to completely cut off the liquid column, preventing dripping from the bottle neck and subsequent foam overflow. This precise control reduces foam overflow by more than 90%, and stabilizes filling accuracy within ±0.5%.

Stable delivery of high viscosity materials also tests equipment performance.

Products such as hair conditioner and facial mask essence can reach viscosities of several thousand centipoises, rendering conventional gravity filling completely ineffective. Servo piston metering technology demonstrates superior advantages in this regard. This system uses a precision-machined cylinder and piston to extract a fixed volume of material in each cycle, pushing it into the container with stable pressure. The introduction of a servo motor allows for precise programming of the motion curve, adjusting the piston speed according to material characteristics. Initial rapid filling by slow, precise filling at the end effectively solves the stringing problem of high-viscosity materials. This technology ensures filling accuracy within ±0.8% for various viscous products while avoiding mechanical shearing that could damage the active ingredients.

Equipment protection against corrosive liquids is crucial to system lifespan.

Products such as chlorine-containing disinfectants and acidic cleaning agents can corrode ordinary metal parts, leading to equipment damage and product contamination. The solution is to use specialized corrosion-resistant materials throughout. Key flow channel components utilize 316L ultra-low carbon stainless steel, whose pitting corrosion resistance is significantly superior to conventional 304 stainless steel. For highly corrosive environments, advanced materials such as Hastelloy and PTFE provide more comprehensive protection. Sealing elements are made of fluororubber or PTFE to ensure excellent sealing performance even after long-term use. While these special materials require a higher initial investment, they can extend equipment lifespan by 3-5 times, significantly reducing overall maintenance costs.

Modern daily chemical filling systems also integrate intelligent control technology. Through real-time feedback from flow meters and weighing sensors, they automatically compensate for filling volume deviations caused by changes in temperature and viscosity. This closed-loop control system ensures stable filling accuracy under various production environments.

In summary, the special filling solutions for the daily chemical industry, through the organic combination of anti-foaming valve technology, servo piston metering, and the application of special materials, successfully solve the filling challenges posed by high-foaming, high-viscosity, and corrosive liquids. These technological innovations not only improve filling accuracy and production efficiency but also provide reliable guarantees for product quality, helping daily chemical companies gain an advantage in fierce market competition. With the continuous improvement of intelligence, daily chemical filling technology will continue to develop towards greater precision, efficiency, and reliability.
