Construction procedures | construction method | Main materials - auxiliary materials | Reference amount |
Plain ground | Do a good job in waterproofing treatment | ||
undercoat | Scrape and apply epoxy primer | DS-30# | About 0.15kg/m ² |
screed | Scrape the mortar layer with medium coating and quartz sand | DS-400- Quartz sand | 0.25-0.75kg/m² |
Apply putty layer with intermediate coating and scraping | DS-400 | 0.15kg/m²一遍 | |
Carbon black layer | Scrape and roll the conductive carbon black coating once | DS-810 | 0.15-0.18kg/m² |
copper foil | Lay copper foil horizontally and vertically at intervals of 1.5-2m (seal the copper foil with Dongsheng DS-401) | DS-900 | 0.25-3kg/m² |
top coat | Roll coating anti-static flat topcoat | DS-401 | 0.12kg/m2 |
Electrostatic wear-resistant layer | Scrape and roll apply polyurethane anti-static and wear-resistant topcoat at the same time | ||
Construction procedures | Coating thickness: generally 1mm-3mm. If it exceeds 2mm, it needs to be sandblasted | ||
Personnel can only enter after 24 hours of construction completion, and heavy pressure can only be applied after 72 hours. (Based on 25 * C, the low-temperature opening time needs to be moderately extended) |
