Dyeing sling required to achieve pure color, color uniformity, no obvious color difference too, if they have a color in sling dyeing process, then we can solve by the following method, Changchun sling, can be reduced chromatic aberration minimum, so as to achieve a uniform shade, can be placed in 2% -4% PALEGAL-SF in which dye tank, acetic acid adjusting the pH 4-5, heated to between 125-135 ℃, treatment in the dye bath 1 -2h stain starts to heat up. About sling attached to a high temperature environment of choice: 1, lifting belt has an upper limit of double limit function. The first stop is the weight limit, lifting belt rigging, the second stop of a conventional electric hoist, lower limit stopper off the fire. 2, since the weight limit protection, electric hoist lifting 90% of rated load from the weight of limiter alarm, flexible lifting belt, lifting 105% of rated load hoist power to stop working. 3, high-temperature insulation protection under the hoist drum shell design and installation of the machine insulation board, lifting belt production process, in order to isolate the heat radiation of the molten metal. 4, lifting the motor and the operation of the motor insulation grade class F and lifting the motor windings built with thermal protection devices. 5, wire configuration metallurgy occasion special high-temperature high-strength steel wire rope. 6, the control mode given priority of remote control, centralized control can also be used. Lifting belt prices, Chen power lifting belt, lifting belt from Hebei Chen Changchun force sling Manufacturing Limited. Hebei chen sling Manufacturing Co., Ltd.
