Zijin Office Chair Renovation

Zijin office chair renovation requires selecting appropriate methods based on the material. The renovation steps for conventional materials and fabric materials are as follows:

Renovation of Office Chairs with Conventional Materials

1. Thorough Cleaning
   First, disassemble removable components such as the seat, backrest, and armrests. Use a soft cloth dipped in a neutral detergent to wipe the frame. For stubborn stains (such as oil stains and glue marks), use alcohol wipes for local treatment. If the seat surface is made of mesh material, it can be directly rinsed with a showerhead. After rinsing, place it in a well-ventilated area to dry and avoid exposing it to direct sunlight, which can cause material aging. Pay attention to dust accumulation in the gaps during cleaning and use a fine-bristled brush to assist in cleaning.

2. Replacement of Wear-prone Parts
   Focus on inspecting parts such as wheels, gas cylinders, and leather seat surfaces. When replacing a gas cylinder, turn the chair upside down, gently tap the bottom of the old cylinder with a rubber mallet to loosen it, and then pull it out. When installing a new cylinder, ensure it aligns with the base hole. Wheels are usually designed for plug-and-play; simply pull out the old wheels with force and insert the new ones. It is recommended to choose silent universal wheels to enhance the user experience. If the leather seat surface is severely damaged (such as large-area cracking or deformation), you can purchase an elastic chair cover online and wrap it directly without complex repairs.

3. Surface Touch-up
   After assembly, test whether functions such as height adjustment and tilt are normal. For paint peeling on metal frames, use anti-rust paint to spot-coat the exposed areas to prevent rust from spreading. For scratches on plastic parts, lightly heat them with a hot air gun (at a distance of 10-15 centimeters) to soften the surface, and then wipe them with a soft cloth to fade the marks. Control the temperature during treatment to avoid plastic deformation.

Renovation of Office Chairs with Fabric Materials

1. Removal of Old Fabric
   Prepare tailor's scissors, a manual staple gun, and a hot air gun. First, use the scissors to cut the connections between the old fabric and the frame (such as seams and adhesive parts), and then use the staple gun to pull out the fixing staples one by one. If the old fabric adheres tightly to the frame (such as glue residue), use the hot air gun to heat and soften the glue (control the temperature at 60-80°C). After the glue softens, slowly tear it off to avoid damaging the frame.

2. Replacement with New Fabric
   Choose wear-resistant tech fabric as the new material. When covering, reserve a 5-centimeter edge for fixing. Lay the fabric flat on the frame, pull it flat from the center to the四周, and use the staple gun to fix it, inserting a staple every 3 centimeters to ensure the fabric is tightly attached without wrinkles. The edges can be folded and then stapled in to increase firmness.

3. Paint Maintenance
   If the frame is made of wood, first sand it with sandpaper (240-400 grit) along the wood grain to remove old paint and burrs. Choose a water-based wood paint (such as white Sanqing paint) for spraying. Do it in three times, with an interval of 1-2 hours between each time, focusing on treating gaps and corners. Maintain a distance of 20-30 centimeters during spraying to avoid runs.
