Product Name：phenolic resin CAS ：7704-34-9   Chemical Properties:  Industrial sulfur is insoluble in water, slightly soluble in alcohol and ether, and easily soluble in carbon dioxide, carbon tetrachloride and benzene. It is a Class II flammable substance with a self-ignition point of 205 ℃. Its dust or steam can form an explosive mixture with air, and it is a flammable solid hazardous substance. As a flammable solid, industrial sulfur is mainly used in the manufacture of sulfuric acid, dyes and rubber products, as well as in the industrial sectors of medicine, pesticides, matches, gunpowder and industrial ceramics, building materials and auxiliary materials.   Application: 1. It is used to control diseases and insect pests and is often processed into a gel suspension. It is safe for people and animals and is not easy to cause pesticide damage to crops Sulfur is a multifunctional agent, which can kill mites and insects in addition to sterilization. It is used to control powdery mildew and leaf grub of various crops, and its effective period can reach about half a month. Sulfur gum suspensions used in vegetables are mainly used to control melon powdery mildew, such as cucumber, melon (muskmelon), pumpkin, etc. When used, 50% sulfur gum suspensions are diluted into 200-400 times liquid spray. Spray once every 10 days or so, generally twice for patients with mild disease, and three times for patients with severe disease. 2. Sulfur is a mineral, which is acidic, warm and toxic, and belongs to the kidney and large intestine Its effect is to kill insects and stop itching for external use. It can be used for scabies, eczema and skin itching. Some people use it to burn smoke to cure itching of male scrotum or female vulva; It can also be ground and spread. It is believed that it produces hydrogen sulfide and pentathiosulfonic acid after contact with skin, which can kill scabies, mold and hair removal. With the development of transportation industry, radial tire will gradually replace bias tire. Therefore, insoluble sulfur as the main curing agent for radial tire production is more attractive. 3. Sterilization Sublimated sulfur, also known as sulfur sublimation, contacts with skin and tissues and generates sulfide under the action of its secretion, which has the effect of softening skin and sterilization. Settled sulfur, also known as sulfur milk, can produce hydrogen sulfide and pentathiosulfonic acid under the action of its secretion in contact with the skin, which has the effect of sterilization and killing scabies. 4. Laxative action Sulfur itself is not active, and it turns into sulfide and hydrogen sulfide after oral administration, which stimulates gastrointestinal mucosa, makes it excited and peristalsis, leading to diarrhea. This process requires the presence of alkaline environment, Escherichia coli, especially lipolytic enzymes. When there are many fatty substances in the intestine, it is easy to produce a large amount of hydrogen sulfide and cause diarrhea. The high concentration of hydrogen sulfide in the air can directly paralyze the central nerve cells and cause death.
