Enhancing Fireproof and Waterproof Performance of PVC Sheets for Ship Superstructure Interior Decoration
Introduction
PVC sheets, including PVC partition panels, PVC coated foam boards, laminated PVC foam boards, coloured PVC foam boards, and PVC sheet green, are popular for ship superstructure interior decoration. Given the high - risk nature of shipboard environments, improving their fireproof and waterproof performance is vital for ship safety.
Fireproof Performance Improvement
Fire - Retardant Additives
PVC partition panels can reduce flammability with phosphorus - based fire - retardant additives, which form a char layer when exposed to fire. PVC coated foam boards use a mix of halogen - and metal hydroxide - based additives. The former suppresses flames by capturing free radicals, while the latter cools the material by releasing water.
Laminated PVC foam boards can add fire - retardant layers during lamination. Coloured PVC foam boards need specialized pigments to maintain both colour and fireproof standards. PVC sheet green can use eco - friendly clay - based additives for fire resistance.
Surface Treatment
Intumescent paint is effective for PVC partition panels. It expands to form a heat - insulating char layer. PVC coated foam boards can undergo plasma treatment to improve coating adhesion. Laminated PVC foam boards can laminate a fire - resistant film. Coloured PVC foam boards can use a clear fire - retardant varnish. PVC sheet green can apply bio - based fire - retardant coatings.
Waterproof Performance Improvement
Sealant Application
Silicone - based sealants seal PVC partition panel joints. High - performance, anti - mildew sealants are used in water - prone areas. PVC coated foam boards need edge sealants to prevent water from entering the foam core. Laminated PVC foam boards require sealants at lamination interfaces. Coloured PVC foam boards can use matching - coloured sealants. PVC sheet green can employ latex - based eco - friendly sealants.
Coating Optimization
A thicker PVC coating can improve the water - resistance of PVC partition panels. PVC coated foam boards can adopt a multi - layer coating system. Laminated PVC foam boards can laminate a waterproof film. Coloured PVC foam boards can use water - resistant pigmented coatings. PVC sheet green can use nanomaterial - containing coatings for better water - repellency.
Conclusion
PVC partition panels, PVC coated foam boards, laminated PVC foam boards, coloured PVC foam boards, and PVC sheet green offer many advantages for ship interior decoration. By enhancing their fireproof and waterproof performance, these sheets can ensure ship safety and contribute to the shipping industry’s development.
