To prevent contamination by abnormal discharge in direct-charging electrostatic atomizers, a new electrostatic atomizer uses a main external electrode (13) and an auxiliary external electrode (17) located radially outward of an atomizer main body (4). A high-voltage supply line (15) for supplying a high voltage to the main external electrode (13) is connected to a head member (5) of the atomizer main body (4) by an additional conductor line (18), in which an auxiliary external electrode (17) is connected between a first and a second resistors (19, 20). When water paint is supplied to the rotary atomizing head (2) through a paint supply passage (10), the rotary atomizing head (2) is connected to the ground potential by the water paint itself, and automatically configured to operate as an indirect-charging electrostatic atomizer.

The invention belongs to the technical field of membrane separation, and provides a positively charged composite nanofiltration membrane and a preparation method thereof. The composite nanofiltration membrane has the positively charged performance, and comprises a separation functional layer and a support layer, wherein the support layer is positioned under the separation functional layer; the separation functional layer is an ultra-thin compact membrane formed by a soaking and coating method; the thickness is within 200nm; the ultra-thin compact membrane is prepared from epoxypropyltrimethyl ammonium chloride chitosan, additives, cross linking agents and solvents. The positively charged composite nanofiltration membrane is a flat plate membrane or a hollow fiber membrane. The commercial epoxypropyltrimethyl ammonium chloride chitosan is used in the functional layer in the preparation process, so that the prepared composite membrane has the positively charged characteristics, so that the high interception rate can be realized on the hypervalent inorganic salts. Meanwhile, the membrane also has high anti-oxidization performance; the use range is expanded. The membrane can also be applied to the treatment of waste water containing heavy metal ions and the treatment of other wastewater containing high oxidability.

The invention discloses a preparation method of a positively-charged hollow polytetrafluoroethylene composite nanofiltration membrane. The method includes the following steps of injecting a carboxylation chitosan aqueous solution into a hydrophobic polytetrafluoroethylene hollow fiber membrane through an injector to obtain an active base membrane, injecting a hyperbranched polyethylenimine aqueous solution into the active base membrane to obtain a middle membrane 1, injecting acyl chloride monomer organic solvent into the middle membrane 1 to obtain a middle membrane 2, injecting deionized water into the middle membrane 2, and putting the middle membrane into a drying box to be dried to obtain the positively-charged hollow polytetrafluoroethylene composite nanofiltration membrane. Reactivity of carboxylation chitosan, hyperbranched polyethylenimine and acyl chloride monomer is adopted, and the membrane preparation process is simple. In addition, due to the unique molecular structure of hyperbranched polyethylenimine, the prepared composite nanofiltration membrane is positively charged, has the advantage of being high in reject rate and can be used for the fields of water treatment and the like.

We describe pH-sensitive endosomolytic polymers, delivery particles containing pH-sensitive endosomolytic polymers. The described particles are capable of delivering polynucleotides to cells from the peripheral circulation with subsequent release from endosomes. The endosomolytic polymers are inactive outside the cell but disrupt membranes upon exposure to an acidified endosomal compartment.
