Evaluate whether the three-in-one filter, washing and drying is of high quality from the following three aspects

- Sep 17, 2020-

The three-in-one filter, washing and drying process enables the materials to complete the three processes of filtering, washing and monotonous in a closed container equipment, which improves equipment utilization, avoids environmental pollution and environmental pollution to materials, and reduces material transfer and discarding. , Save the amount of solvent used, suitable for batch production. Let's talk about how to choose filter washing and drying equipment.


1. Material manufacturing process: as well as titanium material’s excellent corrosion resistance and stability, the difficulty of its processing technology is well known. The titanium material is special, and the typical problem is that it cannot be directly welded with other materials; but from the perspective of application cost, pure The selection of titanium materials is not very accepted. For this type of application, process research and development have been carried out to form a set of "composite titanium processing" process plans. The composite titanium materials are processed on the basis of various alloys for overall equipment processing. The successful application of titanium materials has accumulated many years of technology experience.


2. Material corrosion resistance: For general materials with chloride ion content, from normal to high temperature drying, titanium has excellent corrosion resistance, and it is stable and applicable to hydrochloric acid with a concentration of less than 1%; high-concentration hydrochloric acid and other strong corrosive solutions , Hastelloy is a material for mature applications in the market; non-metallic materials such as polytetrafluoroethylene, etc., are also relatively stable in corrosion resistance, but they are prone to coating peeling during the three-in-one application process of filtration, washing and drying.


3. Service life, performance and stability: Under the premise of ensuring the material, the three-in-one manufacturing process of filtration, washing and drying is the key factor that determines the service life and stability of the later equipment. The heat transfer effect of metal materials is similar. In the heat exchange process The middle is the material; and in the case of alternate use at different temperatures, even different alloy materials have close shrinkage ratios, which are generally more stable.


Since the innovative application of the fully enclosed material conveying system can completely realize the fully enclosed production process from the beginning of crystallization to the end of packaging, the three-in-one filter, washing and drying system is a fully enclosed operating system, and the production process is more in line with GMP requirements. In addition, because the entire production system is a fully closed system operation, materials and solvents can be almost 100% completely recovered, avoiding waste caused by material omissions, residues and solvent volatilization, which has great economic benefits, especially for processing materials This is especially true when the solvent value is higher.
