Experiment
Example 1. screens solvent: uses and has < 10mm length and the < hydrophobic polymer fibers of 50 μ m diameter and high length-diameter ratio (L/D=150).These fibers of 1g are placed in the vial of 20mL and occupy the uncompressed volume of 10mL-15mL., as shown in the center row (10%) of Fig. 1, added the following range of solvent of 10g: RhodiasolvIRIS (1,3-propanedicarboxylic acid of side chain and the dibasic ester of adipic acid), RPDE (dibasic ester of the 1,3-propanedicarboxylic acid of straight chain, succinic acid and adipic acid), Augeo (glyceryl ketal), Polarclean (ether amide), ADMA (alkyl dimethyl amide), DIB (diisobutyl ester) and DEE (the diethyl ester mixture of straight chain).These solvents cover this fibrous matter reluctantly, and this fibrous matter shows as not pumpable wet brushy material.Additionally add solvent (bottom row of Fig. 1) in these bottles and hydrophobic polymer concentration dilution is occupied to only 5% and these fibers whole volumes of this bottle.This fibrous suspension remains dough (plug) under this concentration, and it pumps throughout this material with simply using solvent discharge system difficulties.People still can see that the fiber cluster of white aggregation, it was shown that the dispersion of the difference of single fiber.This example proves, the chopped fiber as provided can not float in liquid medium with high-density suspended.
Example 2. hydrophobic polymer fibers bundle: compress hydrophobic polymer chopped fiber as binding agent by natural guars (Higum1122).The viscosity Higum1122 solution (in 1%w/w concentration) of 15g is joined in the hydrophobic polymer chopped fiber of 5g.Paste is become by admixed together for both materials.Then this paste is rolled onto the spherical bundle of (10mm-12mm) diameter.Then in the convection oven of 65 DEG C, dry these are restrainted overnight.Referring to Fig. 2, it is simultaneously achieved significantly reducing of possessive volume what improve handling feature.These spherolites can pneumatic conveying.
Then being under agitation added to the water by these spherolites, so making these hydrophobic polymer fibers concentration in final suspension is～1%.Simply mix the easy hydration allowing these bundles without special installation.As shown in Fig. 3 (a) and 3 (b), hydrophobic polymer fibers disperses throughout the body of this suspension.Observe that this suspension is stable within some weeks.
