in high-end manufacturing areas such as electronic chips and biomedicine.Cleanroom Speed Chain Conveyor Linehonestlyzero particulate pollutiontogether withTriple speed driveThe dual characteristics of the system make it a key technology to break through the bottleneck of clean production. This conveying system, which combines the principle of mechanical acceleration with cleanroom standards, not only controls the release of particles to within ISO Class 5, but also provides a cleaner environment through the use ofClosed-loop dust suppression designAchieve a dynamic balance between efficiency and cleanliness. In this article, we will analyse its technical core and the logic of landing.

I. The Physical Code of Clean Growth Rate: Reconstruction of Multiplier Chain in Dust-Free Environment

The friction of the rollers of traditional speed chains releases metal particles, whereas the special speed chains for clean rooms are designed to release metal particles by means ofTriple dust suppression structureAchieving a breakthrough:

Engineering Plastic Roller: Carbon fibre reinforced polyether ether ketone (PEEK) material, coefficient of friction reduced to 0.05, particulate release <3.5 particles/m3 (≥0.3μm)
Vacuum adsorption guides: Aluminium alloy guide rail embedded negative pressure chamber, real-time extraction of friction-generated fine dust
Ion wind screen isolation: ±50V static electricity elimination wind screen is set above the conveying line to block the environment from falling dust.

Optimisation of the velocity stacking formula::
In a dust-free environment, the theoretical 3 times the speed of the roller diameter ratio (D/d = 2) due to low-friction lubrication can actually reach 2.92 times (measured value), 7% than the industrial environment.

Industry ObservationsPEEK rollers have a life expectancy of 28,000 hours in a Class 10,000 cleanroom, far exceeding the 15,000 hours of steel rollers, as measured by a chip packaging plant.Non-metallic materials are irreplaceable in clean scenarios.

Core Q&A about Cleanroom Multiplier Chains
