 工業用,主要來自巴西,天然膠乳橡膠樹。巴西原始野生橡膠樹在南美洲亞馬遜河,主要種植于東南亞地區。在1904年推出,中國天然橡膠樹開始,到現在,中國,海南,云南,廣東,福建,廣西等省份的橡膠資源豐富,作為世界主要生產國之一。
   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.
   剛剛新鮮出爐的膠乳膠,白色乳狀液,只有約35%的干橡膠含量。異戊二烯橡膠烴的聚合物主要成份,還含有約65%的水和蛋白質,樹脂,糖和鹽等非橡膠材料的小數額。乳膠,以防止惡化,通常是作為防腐劑氨一定的數額。為了便于運輸,存儲和應用,一般應為新鮮濃縮膠乳60%以上的天然濃縮膠乳干膠含量。
   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.
   天然橡膠的乳膠的主要優勢是一種綜合性能,特別是在對成膜性能,濕凝膠強度高的過程中,容易治愈,收益產品,而且還具有良好的彈性,強度高,伸長率和更小的大蠕變。因此,應用范圍,不僅浸漬制品,擠塑制品,發泡制品,模壓制品可用于天然橡膠乳膠生產,許多非純天然乳膠產品可應用,尤其是在某些產品,并且仍然無法使用替代其他材料。然而,由于天然橡膠乳膠合成產品的品種是容易牙齦,年齡,出身,物候,季節,攻絲系統和其他因素,所以有很大的變異性的缺點,同時,天然橡膠乳膠蛋白本身含有(質量分數為0.015?0.035),易吸濕天然橡膠乳,導電性,耐熱等性能下降相當多,更嚴重的是,乳制品導致天然橡膠接觸過敏。
   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.
   濃縮天然膠乳約10天然橡膠總產量,主要用于浸漬制品,膠乳橡膠絲,乳膠發泡,地毯背襯和粘合劑等五大類產品,使用的百分比,%生產:36%浸漬制品,擠塑15%的絲膠,模壓發泡12%,9%的地毯背襯,膠粘劑9%,4%凝膠棕墊,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%
上一條: 深圳市世邦欣科技有限公司新網站已上線
下一條: 橡膠原料為何一直在漲,甚至有些橡膠原料漲幅超過了60%?何解?
