我国是世界主要产稻国。据1984年统计,稻谷年产量为3561.8亿斤。按20％出壳率计算,在稻谷加工中,可净得712.36亿斤的稻壳。如此丰富的资源,如何有效地利用,实是一件值得考虑和深究的大事。开拓稻壳的综合利用有许多有利因素,其一,稻壳量大面广,价格低廉<每公斤价约2～4分>,其二,稻壳的组成成份中Sio_2的含量约占20％,以致具有防潮,防蛀,阻燃及保温隔热性能,具备了工业利用价值;其三,稻
China is the world’s major producer of rice. According to statistics in 1984, the annual rice production was 356.18 billion kilograms. According to the 20% shelling rate, a total of 71.236 billion kilograms of rice husk can be obtained in rice processing. With such a wealth of resources, how to effectively use it is indeed a major event worth considering and studying. There are many favorable factors for exploiting the comprehensive utilization of rice hulls. First, the rice husks have a wide range of prices, and the price is low (about 2 to 4 points per kilogram). Secondly, the content of Sio_2 in the composition of rice hulls accounts for about 20%. So that it has moisture-proof, flood-proof, fire-retardant and thermal insulation properties, and possesses industrial utilization value; third, rice
