Manifestation of accelerator type and vulcanization system
The effect of accelerator type on segmental dynamics of the SBR/DeVulcSBR blend vulcanizates is evaluated by dielectric measurement. The dielectric loss spectra of different accelerator type vulcanizates shown in Figure 6 clearly specify that the relatively broad and asymmetric peak with frequency shift of loss maxima is observed. In different
Test and simulation of cement hydration degree for shotcrete
From the test results, when the content of accelerator is 3%, the core temperature of concrete with alkali-free accelerator, alkaline accelerator and without accelerator is 53.2 °C, 45.7 °C and 49.1 °C respectively; (3) Comparing the test results of (a) and (b) in Fig. 2, it can be seen that when the content of accelerator is increased from
Effect of Temperature and Accelerator on Gel Time
In this study, we examined the effects of different temperatures and accelerators on the gelation (gel) time and compressive strength of a Polyethylene Terephthalate (PET)-type unsaturated polyester resin anchorage agent. First, the formation temperature of 20–70°C was simulated using self-made test equipment. N,N-Dimethylaniline (DMA), N,N-dimethylp-toluidine (DMT), and
Influence of accelerator type and dosage on the durability
One accelerator was composed by an aluminum hydroxysulfate solution, while the other was based on a sodium aluminate solution. These accelerators were selected to cover the types commonly found in practice, following our previous publication . They are identified as AF and AK, respectively, and their properties are presented in Table 4.
Determination of the photon spectrum of a therapeutic linear
1 Introduction. The determination of the dose near the maze entrance of linear accelerator (LINAC) rooms is a crucial aspect of radiation protection in modern radiotherapy departments. 1 The photon energy spectrum and radiation components at this location are required to achieve good dosimetric precision, 2 but few studies have determined the energy spectrum outside LINAC rooms.
Effects of Accelerators on Mobility of 14C-2,4
Effects of diethyl suberate (DESU), diethyl sebacate (DES), dibutyl suberate (DBSU), dibutyl sebacate (DBS), and tributyl phosphate (TBP) on diffusion of 14C-2,4-dichlorophenoxy butyric acid (2,4-DB) across cuticular membranes (CM) was studied. Astomatous CM were isolated enzymatically from Stephanotis floribunda Brongn. leaves, and diffusion was measured at 20 °C. The alkyl-substituted
Effects of Accelerator Type and Curing Temperature
Effects of curing temperature and accelerator type on tensile properties of natural-acrylic rubber blends (NR:ACM) were investigated. Three different types of accelerators namely, MBT, ZDEC and DPG, were separately compounded with the rubber blends (50/50, % w/w) along with stearic acid, ZnO, sodium stearate, and sulfur (S) on a two-roll mill.
(PDF) The Effect of Accelerator Types on the Phosphated Zn
The Effect of Accelerator Types on the Phosphated Zn-%12Ni Electrodeposite Coating. Determination of porosity . is an important task in controlling the quality of phosphate lms.
Materials | Free Full-Text | The Effect of Accelerator Dosage
By using a 6% accelerator, the deformation of the lowest layer is even reduced to 0.3 mm. By calculating the deformation modulus E d, the effect of accelerator dosage on the mechanical properties of fresh concrete could be quantified. For material with 6% accelerator compared to a 0% accelerator, the deformation modulus is about 14 times higher.
Release of dithiocarbamates into artificial sweat from latex
The effect of the storage time on the extent of release of ZDEC into artificial sweat from vulcanizates prepared with various amounts of ZDEC was studied. The result showed that ZDEC migrated significantly to the surface of the vulcanizates upon storage, and the amount that migrated increased with an increase in the shelf time.
Effect of accelerators on thoria based nuclear fuels
Effect of accelerators on thoria based nuclear fuels for rapid and quantitative pyrohydrolytic extraction of F− and Cl− and their simultaneous determination by ion chromatography Pyrohydrolysis is a fast, reliable and convenient method for the decomposition of solid refractory samples.
