工业用,主要来自巴西,天然胶乳橡胶树。巴西原始野生橡胶树在南美洲亚马逊河,主要种植于东南亚地区。在1904年推出,中国天然橡胶树开始,到现在,中国,海南,云南,广东,福建,广西等省份的橡胶资源丰富,作为世界主要生产国之一。 Industrial use, mainly from Brazil, natural rubber latex Hevea. Brazil Hevea original wild Amazon in South America, is mainly cultivated in Southeast Asia. Introduced in 1904, China began to natural rubber trees, to the present, China, Hainan, Yunnan, Guangdong, Fujian, Guangxi and other provinces have rich resources of rubber, as the world's one of the major producing countries. 刚刚新鲜出炉的胶乳胶,白色乳状液,只有约35%的干橡胶含量。异戊二烯橡胶烃的聚合物主要成份,还含有约65%的水和蛋白质,树脂,糖和盐等非橡胶材料的小数额。乳胶,以防止恶化,通常是作为防腐剂氨一定的数额。为了便于运输,存储和应用,一般应为新鲜浓缩胶乳60%以上的天然浓缩胶乳干胶含量。 Just fresh out of gum latex, a white milky liquid, dry rubber content of only about 35%. The main ingredient of rubber hydrocarbon isoprene polymer, also contain about 65% of water and a small amount of protein, resin, sugar and salt and other non-rubber material. Latex in order to prevent deterioration, usually a certain amount of ammonia as a preservative. In order to facilitate transportation, storage and application, the general should be as fresh latex concentrate more than 60% dry rubber content of natural rubber latex concentrate. 天然橡胶的乳胶的主要优势是一种综合性能,特别是在对成膜性能,湿凝胶强度高的过程中,容易治愈,收益产品,而且还具有良好的弹性,强度高,伸长率和更小的大蠕变。因此,应用范围,不仅浸渍制品,挤塑制品,发泡制品,模压制品可用于天然橡胶乳胶生产,许多非纯天然乳胶产品可应用,尤其是在某些产品,并且仍然无法使用替代其他材料。然而,由于天然橡胶乳胶合成产品的品种是容易牙龈,年龄,出身,物候,季节,攻丝系统和其他因素,所以有很大的变异性的缺点,同时,天然橡胶乳胶蛋白本身含有(质量分数为0.015〜0.035),易吸湿天然橡胶乳,导电性,耐热等性能下降相当多,更严重的是,乳制品导致天然橡胶接触过敏。 The main advantage of natural rubber latex is a comprehensive performance, specifically in the process on the film-forming properties, high wet gel strength, easy to cure, income products, but also has excellent flexibility, high strength, large elongation and more little creep. Therefore, the application scope, not only impregnated products, extruded products, foam products, molded products can be used natural rubber latex production, and many non-pure natural latex rubber products can be applied, especially in certain products, and still can not use other materials substitution. However, due to the biosynthesis of natural rubber latex is the product of varieties susceptible to gum, age, origin, phenology, season, tapping systems and other factors, so there is great variability of the shortcomings; the same time, natural rubber latex protein itself contains a considerable number of (mass fraction of 0.015 ~ 0.035), prone to natural rubber dairy moisture absorption, electrical conductivity, heat and other performance degradation, even more serious is that dairy products cause natural rubber contact allergy. 浓缩天然胶乳约10天然橡胶总产量,主要用于浸渍制品,胶乳橡胶丝,乳胶发泡,地毯背衬和粘合剂等五大类产品,使用的百分比,%生产:36%浸渍制品,挤塑15%的丝胶,模压发泡12%,9%的地毯背衬,胶粘剂9%,4%凝胶棕垫,皮革2%,其他13% Natural rubber latex concentrate production of approximately 10% of the total output of natural rubber, mainly used for impregnation products, latex rubber thread, latex foam, carpet backing and adhesives and other five categories of products, the percentage: 36% impregnated products, extruded plastic 15% silk, molded foam 12%, 9% of the carpet backing, adhesive 9%, 4% gel Zongdian, leather 2%, other 13%
