Among the solvents studied for gel-spinning UHMWPE fiber, paraffin oil and decahydronaphthalene
(also known as decalin) are arguably the most successful spin-solvents used in industrial manufacturing.
Wood content was analyzed by dissolving a sample of the ovendried composite in decahydronaphthalene
Evonik will also be introducing its new VESTASOL brand of specialty solvents, including isophorone, trimethylcyclohexanone (TMC-one), tetrahydronaphthalene (THN), and decahydronaphthalene
The coal fuel, decahydronaphthalene
, stood up to temperatures as high as 500 [degrees] C.
5-g samples by the procedure of Goering and Van Soest (1970), with the exception that sodium sulfite and decahydronaphthalene
were excluded from the reflux solution.
The NDS was prepared according to Van Soest and Wine (1967), except that sodium sulfite and decahydronaphthalene
was used as spin solvent in the previous study to demonstrate the feasibility of the mechanical solvent removal process.
The mechanical solvent removal method investigated in this study applies to both volatile and nonvolatile spin solvents; however, the focus of this study was on decahydronaphthalene
For gel-spun UHMWPE, common spin-solvents include decahydronaphthalene
and paraffin oil and these spin-solvents induce a well-defined gel-transition between 101 and 108[degrees]C for UHMWPE as measured by parallel-plate rheometry .
Intrinsic viscosities of the polymer samples were determined in decahydronaphthalene
at 135 [degrees] C using an Ubbe-lohde viscometer.
3 g specimens were wrapped in a stainless steel mesh and immersed in 1000 ml of boiling decahydronaphthalene
(decalin) contained in a round bottom flask fitted with a reflux condenser.
8], where [eta] is the intrinsic viscosity of the polymer measured in decahydronaphthalene
at 135[degrees] C.
