1. Concept: Cold-bonded wall covering is glued to the wall with ordinary wallpaper glue or environmental protection glutinous rice glue (plant glue), and then laid directly.
2. Environmental protection: At present, environmentally friendly plant gum is used in the market.
3. Durability: Cold glue wall covering will not fade and deform due to surface high temperature setting process. The base adopts patented advanced coating foaming flocking technology, and cooperates with environmental protection plant glue, so that the wall covering can be more firmly attached to the wall, and its service life is at least 15 years.
4. Disadvantages: You need to carry glue dispensing equipment such as glue and batching bucket, and you can't operate it by yourself (because the wall is covered widely and has weight).
5. Construction: gluing, hanging cloth, scraping and trimming.
Second, hot glue wall coating.
1. Concept: Hot glue wall covering, commonly known as glue-free wall covering, means that wall covering has its own glue on the back, so it doesn't need to be glued during construction, and it is directly glued to the wall with a steam iron.
2. Environmental protection: Hot melt adhesive can be divided into EVA hot melt adhesive, polyamide hot melt adhesive, polyester hot melt adhesive, polyamine hot melt adhesive, polyester hot melt adhesive, polyolefin hot melt adhesive and other chemical products. The main component is APEO. It is easy to decompose slight gas at high temperature, which is harmful to human body for a long time.
3. Durability: Hot glue wall covering will damage the waterproof and antifouling coating on the surface due to high temperature heating, which will easily lead to hot glue on the back, and the wall surface will bulge at high temperature, with short service life.
4. Disadvantages: the internal corner of the wall is not easy to construct; High temperature transportation or high indoor temperature will affect the service life; The technical maturity of back glue needs to be tested, and whether the glue composition is environmentally friendly needs to be discussed; Whether the function of high temperature on multifunctional nano-coatings in wall coatings exists or not needs to be observed. In the process of hot glue (non-nanotechnology) construction, the mutual penetration between the wall and the cloth base affects the air permeability.
5. Construction: hanging cloth, ironing and trimming.
