W. According to the amount of propellant in the projectile launch process, the projectile projectile launching system uses a multi-stage vacuum diffusion chamber, a fast iet shut-off valve and two kinds of conduits to restrict the propellant to enter the discharge vacuum chamber. There is no large leakage in the entire launching system. Q calculation results show that this launching system leaves room for vacuum load considerations, the layout of the restricting flow conduits and the matching of the vacuum pump are reasonable, and it fully meets the requirements of the HL2A device tokamak discharge experiment.
Low Temp. Levelling Agents For Polyester
Atmospheric pressure dyeing of polyester, wool/polyester, polyester/acrylic, polyester/nylon and other fabrics and yarns.
Swollen polyester fiber, greatly improves the yielding rate of disperse dyestuff at low temperatures; excellent dye migration and high temperature dispersion to prevent dyeing defects, also can be used for correcting and stripping of uneven dyeing.
low temperature, disperse dyes, color yielding, plasticizing and puffing effect, Atmospheric pressure dyeing
