纳米碳酸钙对SBR胶料性能的影响

试验研究纳米碳酸钙对SBR胶料性能的影响。结果表明，单用纳米碳酸钙填充SBR时，随着纳米碳酸钙用量的增大，胶料的硫化速度加快，硫化胶的硬度、拉伸强度和撕裂强度增大，回弹值减小，耐磨性和抗湿滑性能提高；纳米碳酸钙与炭黑N330并用填充SBR时，随着纳米碳酸钙用量的增大，胶料的硫化速度变化不大，硫化胶的拉伸强度和撕裂强度减小，回弹值减小，耐磨性下降，抗湿滑性能提高。

Evaluation of carbon black slurries as clean burning fuels

Experiments were performed to examine the pumpability, atomization and combustion characteristics of slurries made of mixtures of carbon black with No. 2 fuel oil and methanol. Carbon black-No. 2 fuel oil and carbon black-methanol slurries, with carbon black contents of up to 50 and 45 wt%, respectively, were pumped and atomized by means of a peristaltic pump and air atomizing scheme, and burned in an 82 kW laboratory combustor. Measurements of slurry spray droplet size distributions indicated mean droplet diameters of approximately 100 and 30 μm for the carbon black-No. 2 fuel oil and carbon black-methanol mixtures, respectively. Particulate emissions from the combustion of slurries containing 47 wt% carbon black in No. 2 fuel oil and 42 wt% carbon black in methanol were approximately 40 and 28 mg dm⁻³, respectively. These paniculate emissions are significantly higher than corresponding emissions from ‘base case’ No. 2 fuel oil and methanol tests (0.75 and 0 mg dm⁻³, respectively). However, in spite of the increased particulate emissions, carbon monoxide emissions from all tests were similar (less than 50 ppm dry, corrected to 0% oxygen, for furnace stoichiometric ratios of 1.05 or greater). In addition, at 20% excess air, nitric oxide emissions from the combustion of the carbon black-No. 2 fuel oil and carbon black-methanol (approximately 50 and 15 ppm, respectively) were approximately half of those measured from the combustion of No. 2 fuel oil and methanol (105 and 30 ppm, respectively). Although not examined here, the use of dispersants, stabilizers and modifications to the atomization equipment could improve the burning characteristics of carbon black slurries.

不同凝聚体分布尺寸的N550炭黑对胶料性能的影响

为满足不同客户的需求,需生产不同聚集体分布的N550炭黑品质。如为满足丁基内胎、密封制品企业的需求,需生产聚集体分布较宽的N550炭黑,以降低生热性及提高流动性;为满足卤化丁基橡胶生产内衬层、胎体胶等,需提供窄聚集体分布的N550炭黑,以提高胶料的强度及弹性。对现有软质炉型来说,生产满足丁基内胎用及密封件用宽聚集体分布N550很容易,但生产窄聚集体分布的N550确非易事。     

Cationic grafting from carbon black

Summary The cationic ring-opening copolymerization of tetrahydrofuran (THF) with a cyclic acid anhydride such as phthalic anhydride (PAn) and maleic anhydride was initiated by acylium perchlorate groups on carbon black to give alternating copolymer, i.e., polyester. Epichlorohydrin was found to act as effective promoter in the copolymerization. The polyester formed was effectively grafted from carbon black depending upon the propagation of the polymer from the surface: the grafting ratio of polyester from THF and PAn was increased up to about 65% with an increase in conversion. The polyester-grafted carbon black gave a stable colloidal dispersion in chloroform.

On the threshold nature of erosive burning

A physical explanation for the existence of the threshold of erosive burning is proposed. It is shown that this type of combustion occurs when the thickness of the laminar sublayer in the turbulent boundary layer becomes smaller than the thickness of the laminar combustion zone. In this case, turbulent flame in the gas phase is formed. Relations are obtained linking the critical (threshold) velocity of the blowing flow and the critical Vilyunov number to the properties of the propellant and the gas resulting from propellant decomposition. Simple exponential dependences on the blowing velocity are found for the burning rate. The simplest representation of the erosive burning rate is obtained using the Bulgakov-Lipanov number, whose threshold value is equal to unity. A new mechanism for the occurrence of negative erosion is proposed, according to which the burning rate decreases during blowing because the boundary layer is displaced, resulting in a decrease in the heat flux from the flame zone to the solid-phase decomposition surface. __________ Translated from Fizika Goreniya i Vzryva, Vol. 44, No. 3, pp. 61–71, May–June, 2008.     

炭黑并用对丁腈皮膜胶料性能的影响

采用低生热的补强配合体系,对比研究了炭黑的种类、用量以及炭黑的并用配比对丁腈橡胶（NBR）皮膜胶料性能的影响;对胶料硫化特性、力学性能及屈挠性能的测试结果表明,炭黑N660的补强效果优于N774,炭黑的最佳用量为70份;随着N550/N660并用配比中N550用量的增加,胶料的拉伸强度、撕裂强度及屈挠性能逐渐提高;当N550/N660配比在40/30~50/20之间时,NBR胶料的综合性能最好;考虑到NBR胶料的性价比,确定40/30为N550/N660的最佳并用比。
