At present, many people are into decoration and prefer to use wallpaper to decorate their new homes. Compared with latex paint and diatomaceous earth, wallpaper is more beautiful, more environmentally friendly and has a longer service life. More people are using wallpaper, and wallpaper glue usage rate is also higher. When editor recently chose wallpaper, store said glue used is glutinous rice glue, which can be eaten without any additives. Among all wallpaper glues, glutinous rice glue has become first choice of many homeowners due to its good viscosity and high factor environmental protection. This piqued my interest. As a material person, I can't help wanting to know truth about glutinous rice glue. After reviewing relevant information, let me listen to editor.
Glutinous rice glue, also known as glutinous rice glue, is an environmentally friendly glue made from pure natural glutinous rice or glutinous rice as raw materials after twelve processes such as glutinous rice cleaning, grinding and drying. Wide range of applications and long lasting tack. Wet glue can be divided into glutinous rice glue and vegetable starch glue according to raw materials for its production. Wet glue, also known as Japanese wet glue, is a special high-performance wallpaper glue. It first appeared in Japan and spread to other regions, so it is also called "Japanese glue" in industry.

The glutinous rice glue combines technology of advanced chemical research institute of Japan, and is result of modernization and reformulation of formula by domestic high-tech research institutes. It is made of pure natural food glutinous rice as main raw material. , When opening glue, just add water and stir evenly before use, no need to add extra thickening glue. Even higher productivity when pasting heavy wallpapers.
The starch glue combines advanced technology of Japan Chemical Research Institute and uses modified starch (chemically modified starch, which is naturally not as environmentally friendly as pure natural glutinous rice glue) as main raw material. adhesive products are mainly products of this type. Because their raw materials do not contain glutinous rice ingredients, they are also referred to as "pseudo-glutinous rice glue" in industry. Most of these "pseudo-adhesive rice glues" are translucent colloids. amount of "thickener" is added, which makes it difficult to adjust during construction, as a rule, it is necessary to add water 2-3 times.
In fact, China was first to use glutinous rice as a building material. The white between brick walls of Great Wall of China is glutinous rice. The main reason for excellent performance of this type of mortar. The researchers also found that this mortar is still best available material for restoring ancient buildings. Mortar is a paste used to fill gaps between bricks, stones, and other building materials. Chinese scientist Zhang Bingjian and his colleagues found that about 1500years ago, builders in ancient China invented a super-strong "glutinous rice solution" by mixing glutinous rice soup with a standard solution. The standard ingredient in solution is slaked lime, which is limestone that has been calcined or heated to high temperatures and then placed in water.
As an assistant in wallpapering, glutinous rice glue needs to go through twelve processes, including glutinous rice cleaning, grinding and drying, from production to delivery. Such a complex manufacturing process requires support of conventional manufacturers, professional teams and advanced technology. Therefore, the glutinous rice glue produced by some unskilled small workshops is not very viscous and poor quality, and environmental protection is not up to standard and safety is not guaranteed.
The editor reviewed product introduction of a certain brand of glutinous rice glue with highest sales volume for a certain cat. After reading whole article, I only found words "The use of edible raw materials, environmental protection and health" as shown in figure below, and then found related patents. The glutinous rice glue formula shows that in addition to water and glutinous rice, cooked glutinous rice glue also contains many additives such as urea, sodium benzoate and white dextrin. Although it is non-toxic and harmless, it cannot be eaten directly. Raw glutinous rice can only be used after cleaning and modification. Therefore, store's advertisement that "it can be eaten directly without any additives" is false, but compared to traditional glue, glutinous rice glue reduces harmful substances such as formaldehyde to a minimum, and is more environmentally friendly.
