Who invented sticky fly paper? What are the main ingredients?

Farmer inventor Liu Delin 1985, with the help of friends, Liu Delin began to develop fly-sticky paper by indigenous method. At that time, there was a kind of sticky fly paper on the market, but it was only sticky and unattractive. It can only "wait for the rabbit", can not take the initiative to trap, and the effect of killing flies is poor. After visiting epidemic prevention experts, he learned that the key to inventing new sticky fly paper was attractant, but there was no effective fly attractant in China at that time. He came to the consulting office of the Municipal Bureau of Chemical Industry to look for information, and was stunned by the vast sea of books, the plowman who had only been in primary school for five years. I've been dizzy for a few days, and I haven't found anything. The staff of the consulting department asked him what he was looking for. He only said that he was looking for information about a chemical that could attract flies. He doesn't know what it is. The staff of the consulting department couldn't help him search, and some people thought that Liu Delin was mentally ill, and advised him to go home and stop dreaming of inventing any new sticky fly paper. Liu Delin came home and thought hard about where to find the fly attractant. Summer busy farming has begun, and every household is fertilizing and planting crops. The day after Liu Delin came home, he came to the field to pour ammonia water in the scorching sun. Strong ammonia suffocated him. Suddenly, he was surprised to find that flies flew to the ammonia bucket one after another. Liu Delin suddenly realized that the smell of ammonia can attract flies, which is really "a breeze". He came to the consulting office of the Municipal Bureau of Chemical Industry again, and the range of chemicals he was looking for was reduced a lot, but Liu Delin still didn't know what kind of chemicals to look for. I asked the domestic staff of the consulting office of the Municipal Bureau of Chemical Industry for several days. His sincere heart touched the staff of the consulting department. They took the initiative to help Liu Delin find chemicals with ammonia smell and related books, and some even helped him make recipes. After more than 300 experiments, Liu Delin finally got the best formula and invented a new type of sticky fly paper, which is not only sticky, but also has a special effect of attracting flies. Tested by epidemic prevention experts from relevant departments of the city, all indicators meet the hygiene standards and can be put on the market. Later, Liu Delin used the habit that flies like to stay on indoor hanging objects in autumn to make "film-type" fly-sticky paper, which can only be spread out for use. When it is used, it is hung in the place where flies come in and out, and the effect of killing flies is better. A new type of sticky fly paper invented by Liu Delin obtained a patent certificate issued by the State Patent Office. The victory of the first battle aroused Liu Delin's enterprising ambition, and he began to develop a new mousetrap without stopping. He first made a mousetrap out of a wooden board and put it in the corner to test the killing effect. A week passed and no mice were caught, but the bait on the board was eaten up by the mice. What's going on here? He kept thinking, improving, testing, improving and testing for several months, but he didn't get satisfactory results. From 65438 to 0987, Liu Delin got to know Associate Professor Zhu Longbiao from the Biology Department of East China Normal University and experts from the Institute of Zoology of Chinese Academy of Sciences, and asked them modestly, which was deeply inspired. In his investigation, he found that the standards of mousetraps on the market are different, the sensitivity is not high and the operation is difficult. When the lever passes through the small hole in the bait board too short, small objects will shake the mousetrap and open it. If the lever passes through the hole too long, the mouse will eat up the bait without opening the clip. Therefore, the rodent control effect is poor. After mastering the problems existing in the existing mousetrap, he is determined to develop a new type of iron plate mousetrap. Without funds, he took out all the 20,000 yuan savings at home and borrowed 65,438+8,000 yuan from relatives and friends. Without time, he simply resigned as the captain of the village agricultural machinery. In order to save money, he designed drawings while learning to open the mold. The drawings were changed one after another, and the molds were opened one after another. Liu Delin devoted all his energy to the development of a new mousetrap. The villagers called him a "rat fan" and his family called him a "rat pest". Through continuous efforts, Liu Delin has made progress in developing new mousetraps, but the rodent control effect is still not satisfactory. It turns out that there is also a problem of the minimum weight for the mouse clip to open. Through the introduction of a professor in biology department of East China Normal University, he learned that rats in China are born with at least 8 grams, that is, only when more than 8 grams of objects pass through the bait board of the mousetrap or eat food on the bait board, the mousetrap will be considered as standard and the mouse catching effect will be good, otherwise it will not be considered as standard and the effect will be poor. According to this minimum weight, he calculated the best distance between the lever and the bait board. Although this mouse clip is only 12 cm long and 5 cm wide. It contains many mechanical principles! The problem of minimum weight of open-ended pliers has been solved, but the problems that are difficult to grasp in operation have not been solved. Liu Delin used his years of experience in dealing with iron plates and being familiar with machinery to add a small baffle behind the lever hole on the bait plate, so as to avoid mistakes when the lever passed through the small hole on the bait plate. At this point, the last level of the new rat trap has been overcome. Liu Delin named the mousetrap 88-I and obtained the national patent. However, he never imagined that a single mousetrap with good experimental effect was hooked up with each other when a group of mousetraps were put together after mass production. This surprised Liu Delin. One stormy night, Liu Delin was drinking alone at home, wondering what was wrong with the mousetrap. Suddenly, an old man broke in from outside the door. I can't say anything. I slapped him twice, which made him dizzy. When I opened my eyes, it turned out that my father-in-law was staring at my nose: "What experiment are you going to do? I asked my daughter to divorce you. " This kept Liu Delin awake all night. The funds raised have been spent almost. Now, should we give up or continue the experiment? After ideological struggle, he made up his mind that he would never give up halfway and never give up until he reached his goal. Liu Delin strengthened his belief and persuaded his father-in-law and his family to continue to overcome difficulties in the future. 1in the autumn of 988, Liu Delin improved the 88i mousetrap. After repeated thinking, he finally found that the problem was the spring. So he changed the "movable" spring into a fixed spring and fixed it with brackets on both sides of the spring, and the problem was solved. Liu Delin named the improved mousetrap 89-II. 1989, 89-II mousetrap obtained national patent. On February 3rd, 199 1 10, more than 20 experts from the Ministry of Health, the Ministry of Agriculture, the Academy of Military Sciences and relevant municipal scientific research institutes appraised the 89-II mousetrap, and agreed that the mousetrap has the advantages of ingenious design, high sensitivity and so on, and it is a powerful rodent control tool. At present, the new fly-sticking paper and mouse killer 89-II invented by Liu Delin have been designated by the Ministry of Health as the national monitoring standard tools for fly and mouse killing. In other words, the density of flies and mice can be estimated according to the number of pests by placing several such tools in a certain range and time. As early as 1978, the Ministry of Health commissioned relevant experts to develop a mouse density monitoring tool, but it has not been successful. But this task was completed by Liu Delin. Now this mousetrap has been widely used in the whole country 1 1 provinces and cities. 199 1 year has exported180,000 sets to the United States, Australia, Singapore and other 10 countries and regions, and the export earned more than 70,000 US dollars. On September1Autumn Canton Fair, more than 70,000 sets were also sold. Small mousetraps have entered the international market and won glory for our country. At present, Liu Delin is a member of the Chinese Preventive Medicine Association and a member of the North-South Rodent Control Cooperation Group in China. Recently, he jointly established "Shanghai Fu Min Environmental Science and Technology Industrial Company" with Fengxian Civil Affairs Bureau and Institute of Environmental Science of East China Normal University to further mass-produce new fly-killing paper and mousetraps to meet the needs of killing "four pests" in various places.
