Abstract The effect of polymer structures on the rubber processing and physical properties of the improved Hycar 1090 low compression set nitrile rubbers was investigated. The molecular weight and acrylonitrile content of a polymer are important variables in determining the compound processing and vulcanizate physical properties. Within the range of 21 to 88 Mooney, a blend of high and low Mooney polymers has approximately the same properties as those from a single polymer of the same Mooney viscosity. The molecular weight distribution was not significantly broadened to become an important factor affecting the polymer properties. All polymers with Mooney viscosities from 21 to 88 showed good properties. An understanding of the structure and properties of this new type of NBR, will help in choosing the right kind of polymer for particular applications.

The research of the expanding broken technology of engine connecting rod (also known as the fracture splitting technology) is based on some known factors which effect on connecting rod splitting to make comprehensive analysis on 36MnVS4, the material of connecting rod which is suitable for the fracture splitting technology, it analyses the effect of each chemical composition in steel on mechanical and physical properties, for material steel of new type fracture splitting connecting rod , and makes a theoretical analysis on the fracture splitting technology of the engine connecting rod. Through the analysis and research, a new method to research the fracture splitting of connecting rod is determined, as well as gets some rules to affect process parameter.

A new type of unbalanced magnetic field for planer magnetron cathode was applied to conduct PE-CVD by the assistance of dc magnetron discharge. A carbon thin carbon was formed on a negatively biased substrated by supplying Ar and CH4. This coating was found to have the physical properties equivalent to the DLC sample by ECR-CVD. This paper describes the sample and efficient DLC coating method based on the PE-CVD mechanism.

How to used non-EU-banned insoluble azo dyes to prepare a new-type colour-display anti-counterfeiting paper(ACP) is investigated in this paper. The ACP will display red spots when it is wiped with alcohol. Through studying its mainly affecting facts ,including the dosage of Naphthol AS-BO ,dosage of Chromophore Red-B, the Chromophore's pH value and the drying temperature etc.,the best optimize technological conditions are obtained of insoluble azo dyes' color-displaying on the paper for the purpose of anti-counterfeiting. After the red spot are displayed in the paper,the chromatic aberration and physical properties of the paper are detected. The results showed that the paper made by adding Chromophore Red-B and Naphthol AS-BO had a very good anti-counterfeiting effect, while its physical properties had only changed a little.

Magnesium slag is an industrial waste residue produced in magnesium smelting. Its chemical composition is similar to Portland cement and has potential activity. After the magnesium slag is foamed, it can be made into a new type of lightweight material, and its forming, mechanical and physical properties were closely related to dry material formula, water-cement ratio and foaming agent amount. In this paper, experiments were carried out to find the ingredients and processes suitable for the forming of foamed magnesium slag, making it have certain mechanical and physical properties at the same time.

Some physical properties of ferric chloride-dimethyl sulfone (FeCl3-DMSO2) melts were investigated. The phase diagram was determined by differential scanning calorimeter and thermogravimetric analyzer. The electric conductivity, measured with computerized direct-current method, increased with increasing temperature and DMSO2 content. The conductivity was maximal (0.02149 S/cm) at 115 °C for 30 mol% FeCl3. The densities of all melts decreased with increasing temperature and DMSO2 content. The equivalent conductivities were given by Λ = κMmix/ρ, where Mmix is the mean equivalent weight of the binary melts. These equivalent conductivities were fitted by the equationΛ =Λoexp(−EΛ /RT), where the activation energies EΛ were 8.63, 22.94, 25.92 kJ/mol for 30, 40, 50 mol% FeCl3, respectively.

AbstractHard bitumens are used in the construction industry primarily in it’s unmodified form, for instance for the production of the so-called traditional roofing felt. Due to the low price of these types of membranes, the use of a popular but expensive modifying agent, SBS copolymer, is not justified economically. Research carried out by the authors has shown that chemical organic compounds belonging to a group of imidazolines may potentially be used as much cheaper bitumen modifier. It was demonstrated that a new type of modifier based on oleic imidazoline, developed by the authors, has a significant impact on improving the physical properties of bitumen. The use of this modifier results in a significant increase in the bitumen plasticity range, both before and after laboratory ageing. In addition, there was a considerable increase of bitumen’s resistance to aging. Its use can help improve the quality and durability of popular waterproofing products manufactured with the use of hard bitumen.
