Tung oil is the best quick-drying oil in vegetable oil in the world, has the characteristics of quick drying, light specific gravity, good glossiness, strong adhesive force, heat resistance, acid resistance, alkali resistance, corrosion resistance, rust resistance, non-conductivity and the like, and has wide application. It is used as main raw material for making paint and ink, and can be used as water-proofing, corrosion-resisting and rust-resisting coating for building, machinery, weapon, vehicle and ship, fishing gear and electric equipment, and can be used for making oilcloth, oilpaper, soap, pesticide and medicinal vomit-producing agent and pesticide, etc.. Tung oil is widely used in construction, paint, new printing (ink) agricultural machinery, electronic industry and other fields because of its characteristics of quick drying, high temperature resistance, corrosion resistance, good water resistance and the like. The tung oil has medical function besides the above functions, and can be used for treating spitting wind phlegm, scabies, ecthyma, burn and scald, chilblain chapping, suppurative inflammation, appendicitis, cholecystitis, tonsillitis and the like. However, it is only used externally, and should not be taken orally, and it will be poisoned after being taken by mistake.
Tung oil obtained by hot pressing of tung oil is dry oil (with an iodine value of 157-170), is heated at a high temperature (200-250 ℃), can form gel due to self-polymerization, and even can be completely cured. This particular property is due to the polymerization of the main component alpha-eleosterin, which is a characteristic not found in other drying oils. The tung oil contains 83 percent of alpha-eleostearic acid and 15 percent of triolein. More detailed data: the mixed fatty acid of tung oil contains 74.5% of alpha-eleostearic acid, 9.7% of linoleic acid, 8.0% of oleic acid, 3.3% of saturated fatty acid and 0.1% of unsaponifiable matter. The other data is as follows: 77% of alpha-eleostearic acid, 10% of linoleic acid, 9% of oleic acid and 4% of saturated fatty acid. The alpha-eleostearic acid molecule contains three conjugated double bonds, so that the alpha-eleostearic acid molecule has various geometric isomers, and saturated fatty acid contains stearic acid and palmitic acid. Tung oil also contains vitamin E, phytosterol, pentosan and several proteins.
A special substance in tung oil is named eleostearic acid, and the substance and oxygen can generate oxidation reaction to form a protective film on the surface of an object. Tung oil is used for waterproof paint in the past, and for example, canvas, wooden boat, oil window paper and the like are coated with the tung oil, so that the waterproof effect is good. Lime oil is also called oil lime, tung oil lime, etc., and is a cementing material, and in the past, the window and door must be sealed and water-proof by using it, and the cooked tung oil and lime are mixed according to the ratio of 1:3, and the tung oil lime is soft, soft and greasy, can be kneaded into groups by hand, can be pulled into threads, can be pulled into filaments, and is yellow in colour, non-sticky, non-rare-soluble and paste-like.
Allicin is a botanical fungicide, the main bioactive component of garlic is a general name, wherein the most important active component is diallyl disulfide, which penetrates through the cell membrane of some pathogenic bacteria and enters cytoplasm to competitively inhibit a sulfhydryl-containing compound (certain protein) to inactivate the compound, so that bacteria cannot carry out biological oxidation, thus destroying metabolism and achieving the effect of inhibiting the growth and reproduction of pathogenic bacteria. Researches show that the allicin has wide pharmacological activity and broad antibacterial spectrum, has good inhibition effect on gram-positive bacteria and fungi, and can be applied to feed additives in animal husbandry, so that the allicin not only can improve the immunity of organisms, inhibit bacteria, kill bacteria and expel insects, but also can induce food and promote digestion. Countries such as the United states, the United kingdom, Australia and the like have dozens of allicin registered products, and the allicin registered products are widely applied to the control of diseases and insect pests on crops such as fruit trees, vegetables, flowers and the like. At present, the allicin is not completely developed in China, and is mainly used for preventing and treating bacterial diseases of crops such as cabbage, cucumber and the like. According to the test data of national agriculture and technology promotion center of Ministry of agriculture, the control efficiency of the garlicin of Chengdu Xinyang in the control of plant diseases such as cucumber bacterial angular leaf spot, cabbage soft rot, rice false smut and the like can reach about 70 percent, and the garlicin has lower toxicity to natural enemy insects. Allicin is a relatively common and low-cost animal bactericide and can also be used as a bactericide for plant diseases.
