We demonstrate the preparation and unique properties of composite vitrimer-like materials containing silica nanoparticles (SNPs). The matrix is composed of polyacrylate-based polymers crosslinked via ...
I magine a tire that could heal after being punctured or a rubber band that never snapped.Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed ...
从石油污染土壤筛选出一株高效石油降解菌JC-106,经细菌形态学、生理生化及16S rDNA 序列分析鉴定为赤红球菌(Rhodococcus rubber).在温度 15~40℃、初始pH 6~8、盐度0~4%条件下培养生长良好.该菌能利用十二烷、二十四烷、正辛烷、邻苯二酚、蒽、萘为唯一碳源生长.在较低温度下能有效降解原油,在 15和 35℃培养 15 d 对原油降解率分别为 41.61% 和 5...
Using the race theme and symbols as a way to frame the discussion, this paper will highlight a variety of ethical issues that can emerge throughout the representation of a client in matters related to...
Most parts of the traditional natural rubber growing regions of India, extending from Kanyakumari district of Tamil Nadu in the South to Kasaragod district of Kerala in the North received excess and p...
To improve the mechanical properties of the natural rubber based magnetorheological elastomers (MREs), rosin glycerin ester was added into the carrier matrix to enhance wettability and dispersibility ...
This experimental work investigates the impact of substituting part of the conventional aggregates with rubber aggregates on certain characteristics of the cement concretes. This incorporation of rubb...
The objective of this work is to investigate the hyperspectral remote sensing potential to detect spectral changes undergone by clones of two rubber trees within Brazilian Autumn, with decrease of rai...
This study aimed at the removal of odorous compounds in gases emitted from rubber processing industries. Simulated odorous gas for test was prepared by mixing fresh air and an odorous gas drawn from ...
The complex dielectric permittivity (Ɛ) and magnetic permeability (μ) of Radar Absorbing Materials (RAM) based on metallic magnetic particles (carbonyl iron particles) embedded in a dielectric ma...
在9R-40型揉碎机上设计安装径向强制喂入装置,通过改变揉碎机主轴转速、喂入辊转速和喂入口处锤片形状,进行揉碎机的性能试验。采用正交试验方法分析3个因素对揉碎机性能的影响,得出了生产率的最优组合参数为:揉碎机主轴转速为2980r/min、喂入辊转速为267 r/min、锤片形状是槽型锤片。带径向喂入装置的揉碎机与不带喂入装置、采用人工喂料的原机对比试验表明,生产率提高了30%左右。
Magnetorheological elastomer (MREs)-based devices often operate at cyclic loading and high temperature conditions, which may cause fatigue and aging problems of MRE materials. This paper investigates ...
The workplace environment in factories producing ribbed smoked sheet rubber (RSS), the interiors which are heavily contaminated by wood burning smoke, was evaluated with a focus on the concentration ...
Mechanical behaviour of elastomers depends strongly on crosslink density. The cross linking of rubbers and thermoplastic polymers is a well-proven process of the improvement of the thermal properties ...
简要分析了多环芳烃(PAHs)的危害及水泵橡胶密封件中PAHs的来源,首次采用了水泵密封件中多环芳烃的超声萃取气相色谱-质谱(GC-MS)联用的测定方法。优化了超声萃取条件,确定了16种PAHs的分离和测定条件。样品经过超声波萃取,采用选择离子监测模(SIM)定性和定量检测水泵密封件中多环芳烃,用内标法对PAHs进行定量分析。用加标回收方法试验确定方法的准确度。结果表明:16种PAHs平均回收率为...
