Frequently Asked Questions (FAQ)
What are the primary materials used in sintered mesh filter cores?
Sintered mesh filter cores are primarily manufactured using SUS304 and SUS316L stainless steel for enhanced corrosion resistance. Special materials such as Titanium alloy and PTFE are also used to withstand extreme temperatures and specialized acidic or alkaline chemical environments.
How does a 6-layer sintered mesh differ from a 5-layer sintered mesh?
The six-layer sintered mesh adds an 8-12 mesh square hole support layer to the standard five-layer structure. This structural upgrade increases the flow conduction performance by 30% and allows the filter to withstand higher operating and burst pressures.
What temperature range can a stainless steel sintered mesh filter tolerate?
Standard stainless steel sintered mesh filters can operate continuously in a temperature range from -200℃ to 650℃. For short-term exposure, titanium alloy versions can withstand temperatures up to 800℃, while PTFE models are rated up to 200℃.
What is the recommended cleaning process for sintered mesh cartridges?
Sintered mesh cartridges can be cleaned physically via backwashing (water/air) or ultrasonic baths (40℃ warm water for 30-60 minutes). For chemical cleaning, use a 5% NaOH solution for corrosive media or citric acid for organic residue. High-temperature baking at 600℃ is also viable to burn off polymer residue.
How do I choose the correct filtration precision for my application?
The choice depends on your industry requirements: a precision range of 1-100μm is generally recommended for pharmaceutical applications, while 50-300μm is typical for petrochemical crude filtration. High-precision PTFE models are available down to 0.3μm for specialized applications.
How do you ensure the quality of the sintered mesh filters?
Quality control involves strict spectral analysis of raw materials to verify metal composition, tight process monitoring with a sintering temperature tolerance of ±5°C and interlayer bonding force >15N/mm², followed by final inspections including 100% airtightness testing and 100-hour salt spray testing.
