Conductive rubber roller and imaging device

ActiveCN103105761AMeet the resistance value requirementsLow voltage dependencePolyurea/polyurethane coatingsElectrographic process apparatusSurface layerBulk fill
The invention provides a conductive rubber roller. The conductive rubber roller comprises a metal shaft core, an elastic layer packed outside the metal shaft core and a surface layer formed outside the elastic layer, wherein the elastic layer consists of rubber A and at least one of conductive fillers filled in the rubber A; the threshold value range of the conductive fillers in the rubber is as follows: a conductive filler valve is greater than or equal to Zb and is less than or equal to Yb; and b/Yb+c/Yc+...q/Yx is greater than or equal to 1 if the filling fractions of the conductive fillers B, C,...X in the rubber A are respectively set to be b, c,...q. According to the conductive rubber roller provided by the invention, the filling number of the conductive fillers of the elastic layer is limited, and an integral resistance value of the rubber roller is adjusted according to the resistance difference between an inner layer structure and an outer structure layer, so that the conductive rubber roller is less in dependency to voltage, and is less fluctuated by the environment change, the resistance is even in distribution, and the increase of the rigidity of the rubber roller since a mass of the conductive fillers are filled into the elastic layer can be avoided; and therefore, not only can the cost of the material be reduced, but also the whole flexibility of the rubber roller can be guaranteed. The invention further discloses an imaging device which comprises the conductive rubber roller.

Negative pressure bulk tank car device

The invention belongs to the technical field of mechanical loading and unloading equipment, and particularly relates to a negative pressure bulk tank car device. The device comprises a finished product tank, a discharging pipe arranged at the discharging end of the finished product tank, a negative pressure pipe, an exhaust fan, a mounting platform, a lifting device, a telescopic part and a bulk head, wherein the lifting device is arranged on the upper surface of the mounting platform, the lifting device can drive the bulk head to move up and down, the bulk head drives the telescopic part to stretch and retract, the telescopic part and the bulk head are provided with a communicating hollow layer, the hollow layer communicates with one end of the negative pressure pipe, and the other end ofthe negative pressure pipe communicates with the top of the finished product tank. When the negative pressure bulk filling tank device carries out discharging on a carrying vehicle, the lifting device adjusts the position of the bulk head according to an actual height of the carrying vehicle, the dust raising phenomenon can be caused, the bulk head and the telescopic part can be subjected to negative pressure through the exhaust fan, the dust is sucked away and sent back to the interior of the finished product tank to be reused, the dust raising phenomenon is eliminated, the product waste isreduced, the operation efficiency is improved, and the health and environment of workers are protected.

A low-friction, low-smoke, halogen-free, flame-retardant sheath material suitable for air-blown optical cable laying and preparation method thereof

The invention discloses a low-friction, low-smoke, halogen-free flame-retardant sheathing material suitable for air-blown optical cable laying and a preparation method thereof. The sheathing material is composed of the following parts by weight of raw materials: 100 parts of matrix resin, composite filler type flame-retardant 100-150 parts of compound lubricant, 5-15 parts of nano-scale hydrotalcite, 1-2 parts of silane coupling agent, 1-4 parts of compound lubricant, 0.2-0.8 part of compound antioxidant, after mixing, extrusion, In the steps of granulation, cooling, screening and packaging, in the present invention, the friction coefficient of the sheath material obtained through careful formulation selection and processing is as low as 0.1 or less, the extrusion speed is fast, and the rejection rate is low, which is especially suitable for pipelines. In the construction of laying multiple optical cables by air blowing, because of the combination of hydrotalcite and various lubricants, it breaks through the common low-smoke halogen-free flame retardant sheath material due to a large amount of aluminum hydroxide and magnesium hydroxide. 0.25 or more will affect the air-blown laying of the optical cable.

The invention relates to the field of motor packaging, in particular to a preparation method and application of a high-performance motor packaging material. The preparation method of the high-performance motor packaging material comprises the following steps: (1) preparing the resin A; (2) preparing a curing agent; and (3) performing an action process of the resin and the curing agent to obtain the high-performance motor packaging material, wherein the mass ratio of the resin A to the curing agent is 1: (0.7-1.3); the resin A in the step (1) is prepared from the following raw materials: 3, 4-epoxy hexyl methyl-3, 4-epoxy cyclohexyl formate, acrylic polyurethane resin, a toughening agent, a novel functional filling agent, an anti-settling agent and a coupling agent; raw materials for preparing the curing agent in the step (2) comprise methyl tetrahydrophthalic anhydride, polyether polyol, novel functional filling powder, an anti-settling agent and an accelerant. According to the motor packaging material, the modified powder is used as a filling material, so that the motor packaging material has the characteristic of large usage amount, and the cost can be reduced; and on the basis of using a large amount of filling powder, the motor packaging material with relatively good toughness, strength and temperature-resistant effect is prepared.
