What are environmentally friendly glues? What should I pay attention to when using it?
There is no specific type of environmental glue, as long as it is not damaged to the environment, through SGS or ROHS and other environmental tests, are environmentally friendly glue. In the decoration process, the local glue we use is mainly when the wallpaper is pasted, because the area of the paving is relatively large, so the use of environmental protection glue, will not have a good impact on the home environment and family, are the problems that most people attach importance to.
1. Starch glue
Because starch is a natural polymer of green plants through photosynthesis, starch glue is also classified as plant glue, which is a natural environmental protection glue. Starch pulp is generally made from starch and glue, and the materials are rice, wheat, corn, potatoes and other agricultural products, and the starch glue used in industry is generally made of corn. Although the environmental protection is not bad, but the use of glue generally also takes into account the anti-mildew, toughening and other effects, so when the starch glue is equipped, it is also necessary to participate in the starch quality of 0.2%-2% borax. Because of the addition of a lot of thickening agents, it is necessary to add water 2-3 times during the formal construction.
2. Epoxy resin glue
Epoxy resin adhesive, also known as epoxy adhesive, is a kind of water-based adhesive used more frequently. According to different strength and heat resistance levels, it can also be divided into 16 types, such as general adhesive, high temperature adhesive, low temperature adhesive, epoxy resin adhesive film, etc. Because of its special raw materials and structure, this glue has bond strength and chemical resistance, which is particularly important for the wallpaper placement. Especially some of the more wet walls. The cured epoxy resin adhesive has the ability of most molds, and the curing is convenient, and it can be cured in the temperature range of 0 ~ 180 ° C, and the temperature conditions are less required.
3. Sticky rice glue
Sticky rice is relatively sticky, many ancient constructions in China, such as the Great Wall is the miracle of sticky rice. Now the use of glutinous rice glue is improved: pure natural edible glutinous rice as the material, through the purification, grinding, boring and other twelve processes. The use of this adhesive is very convenient, in the opening of the glue only need to add water and mix evenly can be used, there is no need to increase the rated adhesive paste.
The viscosity of glutinous rice glue is very high, especially the improved glutinous rice glue, which can avoid warping and foaming when Posting relatively heavy wallpaper. Regarding our environmental protection, glutinous rice glue has advantages and guarantees both in terms of material and processing. However, when using glutinous rice glue, it is necessary to pay attention to that this glue will have small bumps when the temperature is low, and you can choose a more suitable temperature and climate to post wallpaper, and perhaps handle the bumps carefully when you shop. When using environmentally friendly glue, pay attention to the amount of sizing is not the more the better, but also according to the paper to decide, sizing reasonable to ensure that the bond is strong, and will not present the problem of overflow glue.
