Precautions when operate the silicone sealant making machine

Precautions when operate the silicone sealant making machine


I. Precautions for Operating the High-shear Disperser:

Pre-Start Checks:

Ensure that the mixing blades are secure and that there are no foreign materials residues in the vessel (especially acidic materials can cause corrosion).
Check the hydraulic system oil level and ensure the cooling water in the jacket is circulating properly (to avoid high temperatures that may cause premature curing of the resin).
Test the sealing of the vacuum pump; the vacuum level should be stable above -0.095 MPa.
Material Feeding and Operation:

Feed in stages: First, add liquid resin, then gradually incorporate fillers (such as calcium carbonate and silica) to avoid clumping of powder.
Speed Control:
Run at low speed (300 RPM) for 1-2 minutes for pre-mixing, then switch to high speed (1000 RPM) for dispersion for 15-20 minutes.
If the viscosity of acidic materials is too high, reduce the speed or process in batches to prevent motor overload.
Temperature Monitoring: Maintain a temperature of ≤40°C using jacketed cold water; if overheating occurs, an automatic alarm will trigger a shutdown (to prevent decomposition and evaporation of acidic substances).
Shutdown and Cleaning:

After discharging, immediately clean the mixing blades and vessel walls with a neutral solvent (like ethanol) to avoid corrosion from acidic residues.
Regularly check the sealing rings of the mixing shaft; if leakage is found, replace with acid-resistant fluororubber seals.
II. Precautions for Operating the Semi-Automatic Filling and Capping Machine:

Filling Accuracy Control:

Before first use, perform 3-5 empty calibrations with actual materials, adjusting the piston stroke until the error is ≤±1%.
Regularly clean the filling head filter screen (150 mesh) to prevent blockage by filler particles, leading to unstable output.
Capping and Sealing:

Adjust the capping pressure according to the material of the packaging container (plastic bottles/aluminum tubes):
Plastic bottles: Pressure 0.2-0.3 MPa to avoid deformation of the bottle neck.
Aluminum tubes: Pressure 0.4-0.5 MPa to ensure smooth and burr-free sealing.
Randomly inspect 3-5 bottles per batch for sealing integrity (using push or vacuum testing).
Emergency Handling:

If leaks occur during filling, immediately press the emergency stop button, clean residue adhesive from the track with a spatula to prevent the equipment from jamming after curing.
At the end of each workday, lubricate the guide rails with silicone oil to prevent corrosion of metal components by acidic vapors.
III. Precautions for Auxiliary Equipment:

Hydraulic Press:

Before pressing, confirm that the discharge valve is fully open to avoid excessive back pressure that could damage the hydraulic cylinder.
Use acid-resistant hydraulic oil (like the HFDU series) and change it every 500 hours.
Vacuum System:

Connect the exhaust port of the vacuum pump to an exhaust treatment device (activated carbon to adsorb acidic gases) in compliance with EU and US environmental regulations.
Regularly check the sealing of the vacuum hoses; if vacuum time is extended by over 10%, the sealing rings need to be replaced.
Cooling Water Tower:

Maintain the pH of the circulating water at 6.5-7.5 to prevent corrosion of pipes due to dissolved acidic gases.
Drain the water tank during winter shutdowns to prevent freezing and cracking of the heat exchanger.

Machine Requirement of Making Silicone Sealant And The Function of the Machine

Machine Requirement of Making Silicone Sealant And The Function of the Machine

Core Equipment Configuration List

Raw Material Processing Unit

  • Vacuum Mixer: Used for strong mixing of silicone-based materials and fillers, with a vacuum degassing function (to avoid bubble residues before curing for acidic adhesives). It is recommended to choose a stainless steel model with double-layer stirring paddles and a temperature control system, with a capacity selected based on output requirements (1-5 tons).
  • Three-Roller Mill: Homogenizes the mixed paste to eliminate particle agglomeration and ensure the leveling property of acidic adhesives. The roller material needs to be resistant to acid corrosion (e.g., tungsten carbide coating).

Reaction and Mixing Unit

  • Planetary Mixer: Used for viscosity adjustment of the gel before filling, may integrate a vacuum system for further degassing. A double planetary structure is recommended, with adjustable speeds from 0 to 60 rpm, with power matched to the viscosity of the gel (acidic gels typically have higher viscosity than neutral gels).

Filling and Packaging Unit

  • Semi-Automatic Piston Filling Machine: Specifically designed for filling acidic adhesives into hard tubes (aluminum/plastic). Contact parts must resist acetic acid corrosion (e.g., PTFE coating). Filling accuracy should be ±1%, with a speed of 25-40 tubes/minute, supporting various specifications of 150-500ml.
  • Labeling and Packing Equipment: Semi-automatic labeling machine + manual stacking. Labels should clearly mark corrosion warning labels for acidic adhesives (compliant with GHS standards).

Auxiliary Systems

  • Vacuum Degassing Unit: Configured in segments during mixing, reaction, and filling to ensure the final product is free from bubble defects (bubbles can lower the weather resistance of acidic adhesives).
  • Exhaust Gas Treatment System: The production of acidic adhesives releases trace amounts of acetic acid vapor. Therefore, it requires a caustic spraying tower or activated carbon adsorption device to comply with European and American environmental regulations.
  • Laboratory Testing Equipment: Includes pH testers (to monitor the acidic environment), tensile testing machines (to test adhesive strength after curing), and accelerated aging boxes (to simulate weather resistance).
