Gilding Vermiculite Wallpaper, Natural Substance, Waterproof Wallpaper for Bathroom

Introductionvermiculite is a rare mineral substance consisting of silicate and crystallizing in a monoclinic crystal system. it is natural, inorganic, non-toxic and it swells at high temperature. 
vermiculite is secondary metamorphic minerals that contains aluminosilicate with layered structure. the raw ore appears to mica, usually it is formed by biotite through hydro-thermal alteration or weathering effect. 
few countries produce vermiculite: zimbabwe, australia, south africa, the us as well as xinjing province in china and kola peninsula(russia). Characteristic 1. Raw vermiculite absorbs water when it is heated to 500ºC, but it does not reabsorb until heated to 700ºC, so we are using this character by rising the temperature to 900--1100ºC at which Rare vermiculite does not reabsorb nor mould. After heat treatment, our product is mould proof. 
2. Expanded Vermiculite is layered structure and contains crystal water between layers. Due to its steady chemical property, it is ideal for warm retaining, heat insulation and deadening application. The volume-weight is 50-200kg/m3, low thermal conductivity (heat conductivity coefficient 0.04---0.06 kilocalorie/m3. With its steady chemical property, its related wallpaper product has following advantages: warm keeping, heat and sound insulation. 
3. Vermiculite has good electrical insulating performance, and not dissolve in water, PH 7-8. It is non-toxic and odourless, no side effect to human health. So it is used for wall paper, no only it gives you a cozy sense of natural material, but also makes you feel peaceful and calm. 
4. Vermiculite is a natural substance, so its natural color is slightly different from the wallpaper we are producing. In order to match the color, all the vermiculite, should go through Screening, color separation, dyeing, mixing and surface coating process, then soaked into Water-based paint for stain treatment. Not only it does maintain its original lustre, but also shows the elegant and harmony as natural materials. 
5. Vermiculite is perfect fire-resistant material with A level on fireproofing grade. It is can be transformed into quality Flame retardant paper by replacing its paper base and binder with ones that have flame retardant grade. 
Through a lot discussions and practice, we have developed advanced and unique gilding vermiculite wallpaper based on vermiculite's characteristics, arming to solve other manufacturers' problems as to single product structure. and achieves the goals of Specification differentiation, color diversity, variety normalization while upgrading our product to a new level
