Brief:Papermaking and dyeing auxiliary agent dosing devices are mainly used for the automatic quantitative dosing of sizing agents, reinforcing agents, retention and filtration aids, bactericides, and cleaning agents during the papermaking process. Multifunctional papermaking auxiliary agents are water-soluble linear polymeric electrolytes copolymerized from acrylamide and modifiers. During papermaking, they can form bridging and cloning with the dispersed pulp phase through various mechanical, physical, and chemical interactions, causing fibers and fillers to interlock and improve paper strength. Furthermore, the polar groups of the auxiliary agent molecules, especially cationic groups, aggregate with anionic groups in the pulp microfibers and talc through adsorption and cloning, forming aggregates that settle on the paper sheet. Additionally, the quaternary ammonium groups in the auxiliary agent reduce the surface tension of the aggregates, fibers, and talc, and decrease the contact angle with water molecules, making it easier for water molecules to detach from the paper wire under stress.
Brief:Because water treatment processes often require the pH value of water to be controlled within a certain range, artificially adding acid or alkali to the water is the most direct and effective way to meet this requirement.
Commonly used acid and alkali neutralizing agents include sulfuric acid, hydrochloric acid, calcium ammonia, calcium hydroxide, sodium carbonate, etc.
Brief:The working principle of corrosion inhibitor (scale inhibitor) dosing device: During natural operation, industrial circulating cooling systems are prone to scaling or corrosion due to the combined effects of factors such as hardness, alkalinity, pH value, concentration ratio, temperature, and ambient humidity. Both negatively impact the safety and operational efficiency of the circulating cooling system. To inhibit scaling or corrosion, corrosion inhibitors or scale inhibitors need to be artificially added to the water. Commonly used corrosion inhibitors and scale inhibitors include polyphosphates, zinc salts, polycarboxylate salts, and phosphonates , etc.
Brief:This device mainly consists of five parts: a drug liquid metering system, a dissolution and preparation system, a metering and dosing system, a safety system, and a control system.
Ammonia water is drawn into the metering system via a water ejector, then added proportionally to the dissolution and mixing system to form a homogeneous mixture with demineralized water or condensate. Finally, it is added to the boiler condensate or feedwater via a metering and dosing system. Dosing control can be manual or automatic, based on control signals from a higher-level system.

Brief:This device mainly consists of five parts: a liquid metering pump system, a dissolution and preparation system, a metering and dosing system, a safety system, and a control system.
Hydrazine is drawn into the metering system via a water ejector, then added proportionally to the dissolution and mixing system with demineralized water or condensate, and finally added to the boiler feedwater via the metering and dosing system. Dosing control can be manual or automatic, based on control signals from a higher-level system.
This device can not only add hydrazine, but with slight modifications, it can also add other oxygen scavengers such as carbazide and dimethyl ketoxime.
Brief:Calcium and magnesium hardness in boiler feedwater can undergo chemical reactions or crystallize at high temperatures, forming insoluble scale that adheres firmly to the boiler's heating surfaces. This scale is a poor conductor of heat, hindering heat transfer and potentially causing boiler tube rupture in severe cases. Furthermore, it can induce and exacerbate chemical corrosion of under-scale metals, posing a significant hazard. Although boiler condensate and feedwater undergo rigorous softening and desalination treatment, small amounts of calcium and magnesium hardness still enter the boiler water. If this hardness is not treated, it can also form scale, threatening the safe operation of the boiler. Currently, adding phosphate to the boiler water is the most suitable treatment method, with the reaction as follows:
Basic calcium phosphate is a soft water sludge that is easily discharged with boiler blowdown and will not adhere to the inside of the boiler to form scale.
Brief:completed step-by-step through separate solution tanks . This ensures optimal reaction time within each tank. A constant concentration is maintained to avoid any direct pathway between the pre-treatment tank and the final solution tank. The equipment is automatically controlled by a control box, which is connected to the final solution tank. The level gauge on the tank is connected. Once the liquid level reaches the "low" level, the electric inlet valve is triggered and opens. The contact flow meter then starts the dry dispensing operation, with the dispensing rate adjusted according to the water volume. The concentration is determined to obtain a precise level. Once the "high" level is reached, this cycle stops. Of course, two (or three) stirrers are still operating. This device is also used to mix latex... The system continuously and automatically prepares standard dilution solutions (0.3-5 g/L) from cationic, anionic, or nonionic polymers. Although it is generally believed that the curing time required to prepare standard solutions from latex polymers is much shorter than that for granular polymers, sufficient curing time is always recommended to achieve optimal drug performance.
Brief:In food additive dosing applications, metering pumps typically handle small volumes, often requiring only a single or multiple electromagnetic pumps connected via flexible hoses. For such systems, the pump should be placed directly on the dosing tank. The tank has pre-installed connection points for the metering pump and agitator. The metering pump, flow monitor, foot valve with level switch, tank, drain valve, and agitator can all be integrated directly onto the dosing tank, offering flexible configuration, minimal space requirements, and reduced costs. Other accessories, except for the injection valve, such as pulse dampers, back pressure valves, and control instruments, are integrated into a single PVC panel. On the board, they are placed in different areas. In special cases, different medicine barrels can be used to integrate the accessory back panel with the medicine barrel to meet different customer needs.
