User question: What is the role of quartz tubes in air purification systems?  

Answer: Quartz tube is the core component of ultraviolet (UV) air purification equipment, responsible for efficient transmission of ultraviolet light and achieving sterilization and disinfection.  

User question: How to avoid UV radiation leakage and harm to human safety when using quartz tubes?  

Answer: Professional designed quartz tubes need to have high-purity materials, precise sealing structures, and customized size matching to ensure directional transmission of ultraviolet rays. At the same time, zero leakage protection can be achieved through physical barriers and structural optimization.  

User question: What core problems can your quartz tube solve?  

Answer: We provide high-purity and highly sealed customized quartz tubes to solve the risks of UV leakage, unstable sterilization efficiency, short equipment lifespan, and safety compliance issues, helping air purification equipment operate safely and efficiently.  

The key role of quartz tube in ultraviolet air purification

UV air purification technology relies on short wave ultraviolet radiation (such as UVC band) to destroy microbial DNA/RNA and achieve air and surface disinfection. As a protective shell for ultraviolet lamps, quartz tubes need to meet two core requirements:

-High UV transmittance: ensuring maximum output of UV energy and improving sterilization efficiency;

-Absolute sealing: prevents the leakage of ultraviolet rays and avoids harm to human eyes and skin.

Core technical measures for preventing UV leakage

1. Material selection: high-purity synthetic quartz

-Using low hydroxyl groups (OH ⁻ content<5ppm) to synthesize quartz materials, reducing UV absorption and achieving a transmittance of over 90% (wavelength 254nm);

-High temperature resistance (softening point>1600 ℃) and heat shock resistance, suitable for long-term UV lamp working environment.

2. Structural design: Integrated sealing process

-The tube body and end cap are laser welded or high-temperature sintered to avoid the use of adhesives (which are prone to aging and leakage);

-Optional coated end caps (such as aluminum film coating) are available to further block lateral UV scattering.

3. Customized matching equipment

-Design the pipe wall thickness, diameter, and length based on the customer's device structure (such as purifier cavity size, UV lamp power);

-Accurate interface design (such as flange sealing, thread locking) ensures seamless assembly with the equipment.

Product advantages and customized specifications

Product advantages:

-Safe zero leakage: through airtightness testing (helium mass spectrometry leak detection<1 × 10 ⁻⁸ Pa · m ⊃3;/s);

-Efficient sterilization: UV transmittance>90%, improving energy utilization efficiency;

-Long term durability: resistant to UV aging, with a lifespan of over 10000 hours in high temperature and high humidity environments;

Specification customization service:

-Size range: outer diameter 3mm~200mm, length 10mm~2000mm, wall thickness 0.5mm~10mm;

-Shape adaptation: straight pipe, irregular pipe (bent pipe, conical pipe), double-layer pipe (vacuum pumping/inert gas filling);

-Function extension: Optional ozone barrier coating, anti scaling treatment, anti-static coating, etc.

Application scenarios and problem solving

1. Air purification equipment

-Commercial/industrial purification systems: such as central ventilation ducts in hospitals, laboratories, and food factories;

-Home purifier: desktop/vertical purifier with built-in UV module.

-Problem solved: Traditional glass tubes are prone to breakage and leakage, and their transmittance decays quickly. Customized quartz tubes provide stable sealing and high transmittance protection.

2. Water treatment and surface disinfection equipment

-Quartz tubes are used in UV water sterilization modules to prevent liquid corrosion and leakage of the tube body.

Customer Application Case (Anonymous)

1. German air purifier brand

-Requirement: Develop a new type of UVC purifier that must pass CE certification to prevent UV leakage.  

-Solution: Provide double-layer vacuum quartz tube (outer tube coated with anti UV outer film), with a 12% increase in transmittance and zero leakage test.  

-Result: The product was successfully launched with zero safety complaints within two years.

2. American industrial ventilation system vendors

-Requirement: Customize corrosion-resistant and leak proof quartz pipes for pharmaceutical factory pipelines.  

-Solution: Adopt high-purity synthetic quartz+magnesium fluoride coating to adapt to acidic air environment.  

-Result: The equipment has been running continuously for 3 years without replacement, and the sterilization efficiency remains above 98%.
