II. Product Details (PRODUCT DETAILS)

1. Tungsten Steel Nozzle, Wear-Resistant, Durable and Non-Clogging

(1) High-Hardness Material, Extending Service Life

• Wear & Impact Resistance: With HRC90+ hardness, it can withstand long-term impact of 80-120 mesh abrasives. When sandblasting quartz sand or carborundum, there are no scratches on the nozzle inner wall, and the service life reaches 800 hours (the diameter of ordinary stainless steel nozzles expands after 200 hours, reducing sandblasting precision by 50%);
• Precise Abrasive Control: The 6mm fixed diameter combined with a polished inner wall ensures low abrasive flow resistance, and the sandblasting width is stable at 12-18cm (the sandblasting width deviation of ordinary nozzles reaches 30% after 100 hours of use), ensuring consistent surface roughness (Ra deviation ≤0.5μm) during large-area sandblasting.

(2) Anti-Clogging Design, Reducing Operation Interruption

2. 80-120PSI Adjustable Pressure, Adapting to Multi-Scenario Sandblasting

(1) High-Pressure Rust Removal, Efficiently Removing Stubborn Rust Layers

• Efficiency Improvement: It can remove rust from 150cm² per minute (2 minutes for ordinary sandblast guns), and rust removal for one car chassis only takes 1.5 hours (3 hours for traditional tools);
• No Substrate Damage: Under high pressure, abrasives impact in a "uniform fan shape", avoiding metal substrate deformation caused by local high pressure (e.g., the flatness deviation of thin steel plates after sandblasting is ≤0.2mm), meeting industrial-grade surface treatment standards.

(2) Low-Pressure Texturing, Finely Processing Surfaces

• Uniform Texturing: With fine sandblasting particles (glass bead abrasives), the surface roughness can be controlled at Ra1.6-3.2μm, meeting the adhesion requirements of subsequent painting and coating (coating adhesion increases by 3 times after texturing);
• Flexible Distance Control: The sandblasting range is more concentrated under low pressure, enabling precise processing of workpiece edges and grooves (e.g., texturing of metal badge patterns) without subsequent manual grinding, saving process costs.

3. Lightweight + Humanized Design, Easier Operation

(1) 780g Lightweight Gun Body, No Fatigue in Long-Term Use

(2) 500mL Hopper, Reducing Refilling Frequency

III. Application Scenarios (APPLICATION SCENARIOS)

1. Part Rust Removal in Hardware Factories (Core Scenario)

1. Preparation: Sieve the quartz sand and pour it into the hopper (400mL), connect the air compressor and adjust to 120 PSi, test sandblasting (uniform sand flow without interruption);
2. Bulk Rust Removal: One person operates, keeping the nozzle 20cm away, at a 60° angle to the part, moving uniformly—each part takes 2 minutes (including flipping);
3. Cleaning & Maintenance: Blow the nozzle and hopper clean with compressed air after processing 10 parts (taking 1 minute) to avoid caking of residual abrasives.
   Result: 50 parts are completed in 2 hours (4 hours with traditional sandblast guns), with a rust removal rate of 98%. The surface roughness of the parts is Ra2.5μm (meeting subsequent processing requirements), and the abrasive utilization rate is 72% (saving 20% quartz sand compared with traditional tools).

2. Chassis/Wheel Rust Removal in Auto Repair Shops (Scenario 2)

1. Chassis Rust Removal: Adjust the pressure to 100 PSi, keep the nozzle 25cm away, sandblast uniformly along the chassis beams, focusing on rusty areas—taking 40 minutes;
2. Wheel Treatment: Replace with 120-mesh glass beads, adjust the pressure to 90 PSi, keep the nozzle 15cm away, and lightly sandblast the wheel surface oxide layer—15 minutes per wheel;
3. Finishing & Cleaning: Blow off residual sand particles on the chassis/wheels with a high-pressure air gun, clean the sandblast gun (hopper + nozzle)—taking 5 minutes.
   Result: Rust spots on the chassis are completely removed, and the wheel surface regains a matte texture (no scratches). Customer satisfaction reaches 95%, and the sandblasting service time per car is reduced from 3 hours (traditional) to 1.5 hours.

3. Surface Texturing in Metal Craft Factories (Scenario 3)

1. Debugging & Preparation: Pour glass beads into the hopper (300mL), adjust the pressure to 80 PSi, and test the texturing effect on a waste brass sheet (to ensure Ra2.0μm);
2. Fine Texturing: Fix the badge, keep the nozzle 18cm away, and sandblast in a circular motion at 30cm/s—1 minute per badge;
3. Cleaning & Storage: Rinse the badge with clean water after texturing (to remove residual glass beads), clean the sandblast gun and store it.
   Result: The badge surface has uniform texturing, no local over-roughness or under-roughness. The subsequent paint adhesion meets Grade 1 of GB/T 9286-1998 (no peeling). 100 badges are completed in 2 hours (6 hours with traditional manual grinding).

IV. Frequently Asked Questions (FAQ)

Q1: "Intermittent sand flow" (abrasive on and off) occurs during sandblasting. What is the reason? How to solve it?

1. Abrasive Inspection: Moisture-caked abrasives (e.g., moisture-absorbing quartz sand) will block the hopper filter. Dry the abrasives in an oven (60℃ for 30 minutes), sieve them, and reuse. If the abrasive particles are uneven (containing large particles ＞120 mesh), replace with standard 80-120 mesh abrasives;
2. Sealing Inspection: A loose hopper lid causes air pressure leakage, failing to push the abrasives—tighten the hopper lid clockwise until a "click" sound is heard (sealed in place), and check if the rubber sealing ring inside the lid is deformed (replace with an original sealing ring if deformed for better adaptability);
3. Preventive Suggestion: Store abrasives in a dry environment (humidity ≤60%) and sieve them before each use; pour out the remaining abrasives in the hopper to avoid long-term storage and caking.

Q2: After sandblasting, the workpiece surface has "too deep scratches". Is it due to too high pressure or wrong abrasive selection?

1. Excessive Pressure: Using 120 PSi high-pressure sandblasting on soft materials such as thin steel plates and aluminum alloys is likely to cause deep scratches—reduce the pressure to 80-90 PSi, and increase the nozzle distance to 25cm to disperse the sandblasting impact force;
2. Wrong Abrasive Selection: Using coarse abrasives below 80 mesh (e.g., 60-mesh quartz sand) to process fine workpieces (e.g., brass badges) will cause deep scratches—replace with 100-120 mesh fine abrasives (e.g., glass beads, fine carborundum) to reduce surface roughness;
3. Operation Adjustment: Keep the gun at a 45° angle to the workpiece (not vertical impact) during sandblasting, move at a uniform speed (no less than 20cm/s), and avoid staying at a single point for more than 3 seconds to reduce local over-sandblasting.

Q3: After using the tungsten steel nozzle for a period of time, the sandblasting force decreases significantly. How to handle it?

1. Check Nozzle Wear: Measure the nozzle diameter (originally 6mm) with a caliper. If it is worn to more than 6.5mm, replace it with a new tungsten steel nozzle (original nozzles have the best adaptability; do not mix with other models);
2. Clean Internal Residues: If there are abrasive debris remaining inside the nozzle (e.g., carborundum particles stuck to the inner wall), insert the "needle" included with the gun into the nozzle, gently unclog it, and then blow reverse air from the nozzle tail with compressed air to blow out residual impurities;
3. Maintenance Suggestion: Blow the nozzle clean with compressed air after each use to avoid residual abrasives; avoid dry firing (high-pressure air flow accelerates nozzle wear when there is no abrasive).

Q4: Can a small household air compressor (0.3m³/min) be used? Will it affect sandblasting efficiency?

1. Small-Area Emergency (e.g., one small hardware part, 50cm² area): A 0.3m³/min air compressor can support low-pressure sandblasting at 80 PSi, but the "intermittent sandblasting" method (20s spraying + 10s pause) must be adopted to avoid air pressure drop due to compressor overload (pressure below 80 PSi will reduce sandblasting force). The single sandblasting area should not exceed 1㎡;
2. Large-Area/High-Pressure Scenarios (e.g., car chassis, bulk parts): Must replace with an air compressor of ≥0.5m³/min. Otherwise, problems such as "unstable air pressure → intermittent sand flow/attenuated force → low sandblasting efficiency" will occur, and frequent start-stop of the compressor will shorten its service life (30% shorter than normal use);
3. Adaptation Suggestion: When choosing an air compressor, prioritize models with "displacement 0.5-0.8m³/min and air tank ≥30L". The air tank can stabilize air pressure, ensuring no pressure fluctuation during high-pressure sandblasting and guaranteeing sandblasting force and efficiency.
