A process for preparing PPE microspore dispersion includes steps of: dissolving a high-molecular polyphenylene ether in a first solvent at 45-110&#xb0; C. to form a dissolution liquid; adding processing aids and well mixing the dissolution liquid into a dispersed phase; cooling the dissolution liquid to 42-80&#xb0; C., and adding a second solvent to generate PPE microspores via PPE to wrap around the processing aids; cooling the dissolution liquid to 0-40&#xb0; C. to obtain PPE microspore dispersions for use in application for impregnation processes performed below 40&#xb0; C., thereby high-temperature impregnation equipment are no longer needed, and copper clad laminates made of using the PPE microspore dispersion enjoy excellent physical properties including high Tg, low Dk, low Df and high copper foil's peel strength.

Process for preparing polyphenylene ether microspore dispersion

A process for producing polyphenylene ether involves to keep a combustible solvent at a gaseous concentration below the minimums of explosion, to keep oxygen gas supplied at a gaseous concentration below the limiting oxygen concentration (LOC) of the solvent, and to make use of a reactor having a rotary-sealed mixer sealed with magnetic rotary feedthroughs to prevent static electricity generated, and then to improve safety and yield thereof.

Process for producing polyphenylene ether helping to improve safety and yield

An embodiment of this invention discloses a foldable treadmill comprising a bracket, a platform, a lifting device, a folding frame, a motor, a linear actuator, and a control board, wherein the bracket comprises two supporting sticks, two tracks, and a rear linkage connected with the supporting sticks, the lifting device comprises a rod connected with the bracket, and two pull members respectively arranged at one end of the rod, the folding frame comprises two bars and a link bar, in which the link bar has two ends respectively connect with one bar, a middle portion of each bar connects with the pull member of the lifting device, a front end of each bar is used as a pivotal point to rotate, and a rear end of each bar has a wheel placed in the track, and the linear actuator is horizontally laid on the rear linkage.

Foldable treadmill

A supporting structure for a treadmill includes an outer tube, an inner tube and a spring means. The outer tube has an inner wall and a protrusion. The outer tube at where the protrusion exists has an outer-tube internal diameter r. The protrusion and the inner wall are separated by a vertical distance L. The inner tube is telescoped within the outer tube and has a positioning hole. The inner tube at where the positioning hole exists has an inner-tube external diameter R, wherein (R+L)&#x3c;r. When the inner tube is parallel to the outer tube and the protrusion is aligned with the positioning hole, the spring means enters the protrusion into the positioning hole. When the inner tube is inclined with respect to the outer tube, the protrusion is disengaged from the positioning hole, allowing the inner tube to move within the accommodating space.
