Improvement Prospect Of Castor Industry
Castor belongs to Euphorbiaceae, has alias like kenaf, ricinus communis, castorbeans, castor-oil plant and so forth. Castor was originated from eastern Africa, later incoming from Asia to Americas, lastly spread to Europe.
Chinese language castor was imported from India, now has been over 1,300 years planting historical past. Castor is a temperate zone annual, tropical perennial herb, distributed across China, the northeast, north China acreage are more concentrated.
Castor is thermophilic, has drought resistance, barren resistance, saline-alkaline tolerance, the adaptability and stress resistance are robust. Castor’s root system is developed, along with discipline planting, also can reap the benefits of homes around, farms and limes marginis, barren wasteland and other locations to plant it. Field planting, so long as scientifically manage can obtain significant economic benefits. Castor product improvement is flexible, high financial worth, utilization prospects are extensively. Castor oil has a wide range of makes use of and high financial value, the United States has already taken castor oil as one of many six strategic materials.
The oil content of castor beans was up to 46% -56%, usually every 2.2-2.5kg castor beans can produce 1kg oil, which is other oil crops can not match. Due to castor oil with the characteristics of excessive viscosity, high combustion level (not go bad, not burn at 500-600), properties of crude oil low freezing point (at minus 18 wouldn’t freeze), excessive specific gravity and so on, castor turn into the one raw material to extract castor oil. Most of the merchandise which obtained from petroleum can be obtained from the deep processing of ricinoleic acid, thus castor is regarded as renewable “petroleum” resource, is currently the only one renewable inexperienced oil useful resource which can substitute petroleum. With the speedy development of the aviation trade and the chemical trade, castor oil has been extensively used in the aerospace and precision devices superior lubricants, brake oil and protecting oils. In defense, chemical engineering and different industries even have extra broadly used. Resin pellets nylon eleven which synthesized by castor oil as uncooked supplies is a popular product within the presently international market, extensively used in cars, ships, machine tools, development, medical and different industries. United States, Western Europe and different industrialized regions and nations use castor oil to generate chemical derivatives, now it has been reached more than 3000 kinds of species, for instance surfactants, plasticizers, stabilizers, nylon, polyurethane, coatings, adhesives, lubricants, grease, brake oil, medicine, food, cosmetics material, anti-rust brokers and other additives. The esterification produced methyl ester, butyl acetate, the major raw materials of producing lubricants, plastics, cosmetics, detergents and the Refinery like. In castor oil fatty acid composition, there are practically ninety% of ricinoleate, if by detoxification remedy, can produce healthy salad.
Castor cake is rich in nitrogen, phosphorus, potassium, is a form of good natural fertilizer, after excessive temperature detoxification can be used as proteins feed for breeding livestock, superior to other dregs of cake. Castor leaves are wealthy in nutritions, the most effective castor silkworm rearing. Castor leaves additionally could be extracted chlorophyll. Castor bark is wealthy in fiber, can be utilized for the uncooked material of papermaking and rayon. Castor properties of crude oil root also contains ricinine and toxalbumin, can be utilized as biological insect-resist brokers. Castor shell can produce activated carbon.
In accordance with the survey, the international market demands for greater than 10 million tons of castor yearly, but the production is simply about 2 million tons, the gap could be very large. With the depletion of the world’s petroleum resources, castor oil used as bio-energy is an inevitable trend, castor will grow to be the necessary “energy crops”, castor beans and castor oil demand will likely be rapidly expanded. The development prospects of castor trade shall be very shiny.
