The reading and saving value are directly related to the correct choice of binding process method and the type of binding material. For example, for high-end books that generally have preservation value, it is necessary to select hardcover processing that can be preserved for a long time. The binding materials must also match the grades of the books in order to obtain the desired results; general reference books or long-term books should be used for their useful lives. Determine the installation method and materials; simple and short-lived books and magazines can use simpler methods.
However, judging from the market for books and magazines and the amount of books published nationwide, the number of adhesive-bonded packages accounts for nearly 60% of the total number of books installed. We do not deny that wireless glue has many advantages, such as fast publishing and short cycle, and it is suitable for modern fast-paced, labor saving and material saving. Low cost, but there are many deficiencies in this processing method. E.g:
(1) The shelf life of EVA hot-melt adhesives (or other resin adhesives) has not been truly measured, and they are always aging, so it is not easy to preserve them for a long time; now there are some books that are glued with wireless glue in only three to four years. The entire book becomes a loose-leaf page, with colloidal aging and no binding ability, so books that require long-term preservation and frequent use are not recommended.
(2) Thicker books (generally referred to as thicker than 15mm), which are not easy to read during reading, must be held by hand, and after reading too many times, the book's front notch protrudes, and the back of the book is concave. The entire book is deformed.
(3) Bonding is not strong, easy to page, break, affect reading, etc., which makes wireless Glue Binding become the most installed one of the book binding quality problems.
Some publishers are eager to produce books. To reduce costs, this book should be booked in batches or applied to hardcover books. It must be designed as a very thick, flat-packed, glue-bonded book. The result is more likely to cause problems. For example, a publisher needs to create an A5-size (210mm x 148mm), 48mm-thick, flat-packed wireless glue book, suggesting that it be done either in lockline or in 2-3 volumes for wireless glue. If such a thick, so small book is to be made into a wireless glued paperback, the result will be: unable to read flat, hold down the hand to read; the front incision is not uniform and the "big belly" becomes a round The appearance of the whole book is changed; the pages are dropped, the posts are dropped, and the book core is broken. After a few years, they all become loose pages; they cannot be firmly bonded and their life span is shortened, and they cannot be stored for a long time.
China is the first country in the world to have bookbinding technology. The number of binding methods and styles is the largest. There are more than 10 kinds of binding methods, and there are also 4 or 5 types commonly used nowadays. Therefore, there is a wide range of choices for making books. However, as far as the current situation is concerned, no matter Most of the books are glued in plain paper with wireless glue. It is not quite normal. It is better to choose the right installation method according to the specific situation. Otherwise, some books with preservation value will become obscure and not easy to use and save.
