Bookbinding hot melt adhesive

Cold glue wall cloth Definition: Cold glue refers to the use of environmentally friendly vegetable gums (potato-starch gum, glutinous rice starch gum), first gluing on the wall, and then directly paving.
Construction process: gluing, draping, scraping, trimming Advantages: mainstream products, mature technology, easy to use, glue environmental protection issues have been through many years of market certification (widely used in the wall fabric paste project), customer glue (plant glue) (Potato starch glue, glutinous rice starch glue)] can be selected according to their own needs and conditions. The back of the wall cloth has a foam coating or a non-woven fabric, the glue does not affect the air permeability, and the service life has been recognized by the market.
Disadvantages: Need to carry glue, batching cylinders and other plastic equipment, two people with the operation (because the width of the wall cloth, weight)
Thermal glue wall cloth Definition: Hot glue is also called glue-free, which means that the back of the wall cloth is self-adhesive, no glue is needed during construction, and the steam iron is used to directly adhere to the wall surface.
Construction process: hanging cloth, hot, cut edge Advantages: no glue, easy to carry (but with steam iron and other processing tools); single can barely operate.
Disadvantages: The wall angle is not easy to construct; high temperature or high indoor temperature will affect the service life; hot glue is also relatively environmentally friendly, the impact on the breathability of cloth, is an uncertain factor, high temperature easy melt, play drum, off .
Non-woven bottom wall cloth Non-woven bottom: It is composed of oriented or random fibers on the basis of fabrics. It is a new generation of environmentally-friendly materials, featuring moisture-proof, breathable, non-toxic, non-irritating, recyclable and other features. Thicker.
Construction: Now many wall coverings are made of non-woven fabrics. The construction master must pay attention to the application, and must use a soft brush to stick the cloth. If you use a hard squeegee on the wall, excessive force on the patch will produce a little on the edge. Similar crease scratch marks, hard-scraping, although the surface fabric is smooth, but the back of the non-woven fabric is still a little wrinkled, so that customers think it is a quality problem. Please paste in a uniform direction when pasting. If there is a small bubble after the paste, please use a small syringe to inject a certain amount of glue (about 1/3 of the amount of glue injected into the bubble, you can decide on your own), then scrape the wall cloth . Non-woven fabrics tend to have creases, and high-precision glossy surfaces tend to have irregularities on the sides.
Coating bottom wall cloth Coating bottom: Wall cloth has excellent anti-pollution ability, maintains long-term cleanliness, and prolongs the service life of wall coverings.
Construction: When the general construction master adjusts the glue, the ratio of the original glutinous rice gum to the clear water is not optimal or not evenly mixed. When the coating is applied to the wall cloth, the coating has a certain function of blocking the water, so the general water is biased. It doesn't matter much more.
