Selection Guide for Powder Feeding Bags and Analysis of Application Fields Powder feeding bags are key equipment for material transfer and feeding in fields such as pharmaceuticals, chemicals, and food. Their design needs to balance hygiene, sealing performance, and operational efficiency. Currently, there are various types of products on the market, covering different specifications and application scenarios. Users can select a suitable solution according to their actual needs. I. Main Types and Characteristics of Powder Feeding Bags 1. Sanitary-grade Powder Feeding Bags These products are made of high-strength materials. The bag body is designed to optimize the powder flow and reduce residue. Some models are equipped with flange joints to ensure no material leakage during the feeding process. Typical specifications include capacities from 5L to 50L, and the feeding port sizes range from 2 inches to 8 inches, which can meet the feeding needs of different scenarios. Some products are sterilized (such as by steam, gamma rays, etc.) and are suitable for aseptic production environments. For example, some sterilization-grade feeding bags are also equipped with HDPE films and sterilization indicators, and the integrity of the packaging is verified through dyeing tests to prov...

Advantages and disadvantages of continuous roll bags

2025-05-10

Advantage Convenient to use: The continuous roll bag is provided in the form of a roll, and users can tear and use it at any time according to their actual needs, without the need for pre cutting or preparing bags of different specifications, greatly improving packaging efficiency. For example, at the supermarket checkout counter, after a customer purchases a product, the cashier can quickly tear off the bag from the roll and pack it. Low cost: The raw material cost for producing continuous roll bags is relatively low, and the production process is simple, which can achieve large-scale production. Therefore, its price is relatively low and suitable for large-scale use. For merchants, using roll up bags can reduce packaging costs. Strong flexibility: Various specifications, sizes, and colors of continuous roll bags can be produced according to different packaging needs to meet the packaging requirements of different products. For example, small-sized roll up bags can be used to package candies, small accessories, etc., while large-sized ones can be used to package clothing, bedding, etc. Disadvantage Environmental issues: Traditional roll up bags are mostly made of non degradable plastics. If not handled properly after extensive use, they can become "white pollution" and cause ...

Tell me the correct usage method of the sampling bottle

2025-05-10

The correct use of sampling bottles Preparation before use Cleaning: New sampling bottles need to be thoroughly cleaned before use to remove any impurities and contaminants that may be present. Choose the appropriate cleaning method based on the material and purpose of the sampling bottle. For example, glass sampling bottles can usually be soaked in potassium dichromate solution, and then rinsed clean with tap water and distilled water in sequence; Plastic sampling bottles can be cleaned with mild detergent and then rinsed with pure water. For sampling bottles used for high-purity sample collection, special cleaning and passivation treatment may also be required. Drying: The cleaned sampling bottle should be dried to avoid moisture affecting the sample. The drying method can be selected according to the material and shape of the sampling bottle, such as drying, air drying, nitrogen blowing, etc. For some moisture sensitive samples, it is necessary to ensure that the inside of the sampling bottle is completely dry. Preprocessing (if necessary): Some special sample collection may require pre-processing of the sampling bottle. For example, when collecting volatile organic compound samples, in order to reduce the adsorption of the sample on the inner wall of the sampling bottle, a layer of an...

Explain the dynamic weighing principle of the dosing weighing system

2025-05-10

The dynamic weighing principle of dosing&weighing system Technological process: Calibration: Establish a linear relationship between mass flow rate and sensor signal using standard materials of known mass, such as glass microspheres. Real time monitoring: During the material conveying process, sensors continuously collect signals and combine them with speed sensors (such as screw speed) to calculate instantaneous flow rate. Closed loop control: PLC dynamically adjusts the feeder speed or valve opening based on the deviation between the set value and the actual flow rate. Key parameters: Flow range: 0.1 kg/h~100 t/h (depending on feeder type and sensor range). Control accuracy: ± 0.5%~± 2% (lower than static weighing in dynamic environments). Repeatability: The RSD (relative standard deviation) of 10 consecutive measurement results is less than 1%. case: Coating of positive electrode material for lithium batteries: The dynamic weighing system controls the slurry flow rate (accuracy ± 1%) to ensure that the density fluctuation of the electrode surface is less than ± 1.5%. ...
