Question 1

Can you provide process verification services?

Accepted Answer

Yes. Songrui offers process verification on pilot reactors: feedstock testing, parameter optimization, 72h+ stability testing, and verification reports. Fees are deductible from production equipment purchases.

Question 2

What reactor is used for Si-C anode materials?

Accepted Answer

The mainstream route is CVD; fluidized bed reactors, with sufficient gas-solid contact and continuous capability, are the core equipment for scale-up Si-C anode production.

Question 3

Difference between FBCVD and fixed-bed CVD?

Accepted Answer

Fixed beds have static particles with uneven transfer and poor coating consistency; fluidized beds suspend particles in a uniform environment, giving uniform coating and scale-up capability.

Question 4

Can pilot reactors reproduce production conditions?

Accepted Answer

The SR-M pilot series shares flow/temperature field design with production reactors, reproducing key characteristics with small scale-up deviation.

Question 5

What is the typical CVD deposition temperature?

Accepted Answer

Silicon-carbon anode CVD deposition temperature is typically 400-650℃, depending on silicon and carbon sources. Songrui SR-series reactors feature zoned temperature control with ±2℃ uniformity.

Question 6

How is CVD coating thickness controlled for Si-C anodes?

Accepted Answer

Coating thickness is controlled by deposition time, gas concentration, and temperature. Typical carbon coating is 2-10nm. Songrui SR-M pilot reactors feature complete data acquisition for process modeling.

Question 7

How to select a gas distributor for fluidized bed reactors?

Accepted Answer

Distributor selection considers particle size, density, and gas velocity. Key parameters include opening ratio (1-5%), pressure drop (0.5-2kPa), and orifice size. Songrui provides custom distributor design.

Question 8

How is silane flow controlled during CVD?

Accepted Answer

Silane flow is precisely controlled using mass flow controllers (MFC). Typical flow is 50-200sccm (lab) or 1-10slm (production), diluted with N2 or Ar to 2-10% concentration. Songrui reactors include MFCs and safety interlocks.

Question 9

How to clean and maintain fluidized bed reactor distributors?

Accepted Answer

Post-batch inert gas purging for 10-15 minutes, weekly pressure drop monitoring, monthly ultrasonic cleaning, quarterly inspection for flatness and cracks, and rotating spare distributors.

Question 10

How to clean carbon deposits from reactor walls?

Accepted Answer

Light deposits: high-pressure water jet. Medium: mechanical scraping with chemical solvent. Heavy: sandblasting after disassembly. Songrui reactors feature special wall coatings to reduce carbon adhesion.

Question 11

What does the pilot-to-production scale-up service include?

Accepted Answer

Songrui provides complete scale-up from SR-M pilot to SR-P production: process data analysis, reactor CFD design, manufacturing and commissioning, process verification, and operator training.

Question 12

What is the warranty and service response for FBCVD equipment?

Accepted Answer

12-month warranty from acceptance. Remote support within 2 hours, on-site service within 48 hours domestically. Warranty covers reactor body, temperature control, and gas distribution systems.

Question 13

Can you provide remote technical support?

Accepted Answer

Yes. Songrui provides remote monitoring interfaces, 24/7 online support, remote troubleshooting, and periodic data analysis. Complex issues are handled with on-site engineers within 48 hours.
