The TBAB CHS has been only studied for about 10 years in air-conditioning and latent-heat transportation areas.
In this article, the TBAB CHS flow in horizontal tubes was experimentally researched.
A flat-plate heat exchanger was used to produce the CHS by chilling the TBAB solution.
There are two types of clathrate hydrate crystal, type A and type 13, produced from the TBAB aqueous solution of the initial concentration equal to 30.
Each suspension was plated on TBAB
to determine the viable count.
Table 1 shows the exact amount of MAn and TBAB used in each experiment and sample was named from sample number 1 to 9.
Effects of molar ratio of ATA and TBAB to MAn grafting on the IIR chain on the final (equilibrium) conversions ([X.
The degree of conversion of MAn to the amideacid group that directly effects on degree of crosslinking is dependent of the molar ratio of ATA and TBAB to MAn grating onto the HR chain.
The cure characteristics and physical properties for mixes A-D reveal that TBAB possesses accelerator activity comparable with NOBS.
With the incorporation of TBAB in the control compound containing accelerator -- activator (mix E and G), the Tc90 value has reduced substantially.
Synergistic effect of TBAB with NOBS is evident from the optimum cure time (Tc90) of mix H.
1] disappears when the reaction proceeds only 10 h in the presence of TBAB
and about 16 h in the absence of TBAB
, implying that the introduction of TBAB
is effective to reaction and can increase markedly the reaction rate.
