361.激光改性对聚氨酯表面湿润性能影响的实验研究
[橡胶和塑料制品业] [2015-10-10]
采用脉冲激光(λ=1 064 nm,v=3 m/s,f=45 k Hz)对聚氨酯(PUR)表面的形貌和湿润性进行改性。利用扫描电子显微镜(SEM)、三维视频显微镜、激光非接触式粗糙度测试仪研究了激光功率对PUR表面形貌的影响规律。结果表明,激光刻蚀后的PUR表面具有孔洞、凸起、沟槽的形貌特征,表面粗糙度增大;功率从1 W增大到7W的过程中,表面粗糙度逐渐增大;功率7~10 W变化时,表面粗糙度逐渐减小。采用SEM、光电子能谱仪(XPS)、SL200B型接触角测定仪探讨了激光改性对PUR表面湿润性的影响机理。结果表明,未经激光改性的PUR表面,水接触角为73°,表明此时PUR表面呈亲水性;激光改性后,水接触有所增大,当P=5 W时,接触角为94°,表明PUR表面已由亲水性变为疏水性,另外发现,随着激光功率的增加,接触角逐渐变大,当P=7 W时,水接触达到最大值123°,分析激光改性前后的PUR表面XPS图谱发现,改性后材料表面的碳氧比例(O/C)有所增加,表明含氧极性官能团增加,理论上更利于PUR表面的亲水性,但由于表面形貌的变化,材料表面仍呈疏水性,符合Cassie模型。所以,激光改性使得PUR表面湿润性发生变化主要是由其表面的形貌发生变化所引起的。

362.印度软包装市场报告（2015-2019年）
[橡胶和塑料制品业] [2015-09-20]
Flexible packaging products are made of easy-yielding materials that can easily change shape to accommodate the product being packaged. Plastic, aluminum, and paper are used to make flexible packaging. These materials undergo printing, lamination, coating, and extrusion to develop products such as plastic bags and pouches, lidding films, foil bags, and sachets. Packaging protects the product from damage and spoilage, and improves its overall aesthetic appeal. It also provides essential information about the product and convenience for consumers in terms of handling.

363.全球橡胶加工化学品市场报告（2015-2019年）
[化学纤维制造业,橡胶和塑料制品业] [2015-09-17]
Rubber is a polymer that is classified into two types, namely, natural rubber and synthetic rubber. Natural rubber is extracted from latex, which is a milky fluid emanating from the bark of rubber trees, while synthetic rubber is manufactured through chemical processes. The rubber is processed using various chemicals to improve its resistance to heat, sunlight, oxidation, ozone, and mechanical stress. Rubber processing chemicals are also an integral component used for vulcanizing rubber. They are classified into different groups based on their functions. The different types that are mainly used are antidegradants, accelerators, processing aids, anti-scorch agents, blowing agents, polymerization regulators, and shortstops.

Blister packaging is a pre-formed plastic packaging used for small consumer goods, pharmaceutical drugs, and medical devices. A blister pack is made of aluminum foil or plastic with a cavity or pocket made from thermoformed plastic. It protects products from contamination, humidity and other external conditions. Blister packs are manufactured through two processes: thermoforming and cold forming. Primarily, these packs are used to package pharmaceutical products such as over-the-counter (OTC) drugs and medicines, and small medical devices. A blister that folds onto itself is known as a clamshell.

365.全球赛车轮胎市场报告（2015-2019年）
[汽车制造业,橡胶和塑料制品业] [2015-09-06]
Racing tires are a range of high-performance tires that are customized for usage in racing vehicles. Production of racing tires is capital-intensive, requiring a significant degree of hi-tech equipment coupled with highly trained and skilled manpower dedicated to the purpose of engineering and manufacture. Racing tires are designed to deliver superior performance, and therefore undergo various quality, durability, and speed tests. Besides natural and synthetic rubber as the primary raw material, textile reinforcements like rayon, aramid, nylon, and polyester are also used to manufacture racing tires.

The history of tires dates back to the mid-1800s, during which only rubber tires, best known as solid tires, were used. Advances in technology led to the replacement of solid tires by pneumatic tires. They were first used in automobiles by the Michelin brothers, who went on to become one of the prominent tire vendors in Europe. Over time, the tire market witnessed new breakthroughs in technology and the entry of many vendors.

367.全球医药行业膜市场报告（2015-2019年）
[医药制造业,橡胶和塑料制品业] [2015-08-19]
Membranes are a type of selective barrier primarily used for separation or concentration of the feed stream. The feed stream is passed through the membrane, which selectively allows some constituents to pass while others are retained back on the surface of the membrane depending on its pore size. The constituents that are allowed to pass are known as permeate and the ones retained back are known as concentrate or retentate. Different types of membranes are used in the pharmaceutical industry depending on their pore size. There are different types of membrane filtration technologies such as ultrafiltration, microfiltration, reverse osmosis, and nanofiltration. Other membrane technologies such as membrane contractors, electrodialysis, and pervaporation are also used but their market shares are smaller.
