In order that powdered whiting inorganic material and resin organic carrier and high polymer material have good compatibility and Plasticity, the present invention propose a kind of special powdered whiting method of modifying of electric wire and its device.
This special powdered whiting method of modifying of electric wire, it is characterised in that comprise the following steps：
1）, will powdered whiting add lapping device in wear into fine powder to the mesh of average grain diameter 1500 ~ 2000；
2）, again water, stearic acid, Aluminate coupling agent and polyester-type oversubscription are added in powder respectively by four feeding pipes Powder stirs to form mixture, and water accounts for the 0.4 ~ 0.5% of total weight of the mixture, stearic acid account for total weight of the mixture 0.9% ~ 1.1%, Aluminate coupling agent accounts for the 1% ~ 1.2% of total weight of the mixture；Polyester type ultra-dispersant agent account for total weight of the mixture 0.5 ~ 0.8%, mixture is put into microwave modification device, carries out microwave heat modification, heating-up temperature is 80 DEG C, a length of during heating 8min;
3）, with drying device drying to water content be 0.1% ~ 0.2%, smash to the mesh of particle diameter 1500 ~ 2000；
4）, with bag-type dust collection device collect after cool down to obtain modified heavy calcium carbonate, the mesh of average grain diameter 1500 ~ 1900.
This special powdered whiting microwave modification device of electric wire, including microwave modification device, lapping device, drying Device and bag-type dust collection device, it is characterised in that microwave modification device, the microwave modification dress are installed under lapping device Put including the first motor, the first cylinder, the second cylinder, screw rod, microwave launcher tube, annular wave guider, hinge and baffle plate, second There is feeding mouth on cylinder, there are four feeding pipes by feeding mouth, screw rod is located in the second cylinder, and screw rod uses saturating microwave material Matter, screw rod are connected with the first motor by flange, and microwave launcher tube is provided between the first cylinder and the second cylinder stage casing, micro- Annular wave guider is installed, baffle plate is arranged on the second cylinder right-hand member by hinge under ripple transmitting tube；Connect on the right side of microwave modification device Drying device is connected to, bag-type dust collection device is connected with the right side of drying device.
Drying device includes frame, power supply, PLC, flow distribution plate, the second motor, electrothermal tube, temperature sensor and stirred Device is mixed, temperature sensor and electrothermal tube are arranged on frame inner wall, flow distribution plate are provided with frame inner wall, frame lower has stirring Device, agitator bottom are connected with the second motor, and shell outside is provided with power supply and PLC, temperature sensor, Microwave emission Pipe electrically connects with PLC, microwave launcher tube and PLC all with power electric connection.
Saturating microwave material is high silica refractory fibre-Pps Pes composite.
Flow distribution plate is 2 ~ 4 pieces.
When in use, powdered whiting is added in lapping device and is ground to the mesh of particle diameter 1500 ~ 2000；After ground, lead to Cross feeding pipe and water, stearic acid, Aluminate coupling agent and polyester type ultra-dispersant agent, the first motor driven screw rod are added into powder Rotation conveying mixture, controls microwave launcher tube to launch microwave by PLC, and annular wave guider shields, baffle plate, Flange and the first cylinder form confined space, calcium carbonate modified under microwave function, chemical bond are generated, because microwave function is From inside to outside, so substantially reducing modification time, when mixture is covered with whole microwave modification device, mixture can absorb microwave Can, being opened at the baffle plate of distal end will not also cause to dissipate outside a large amount of microwaves, and modified mixture, which is fallen into, fraction into drier Blocking mixture breaks into powder by agitator, and by drying, due to negative pressure, the interlayer that mixture is formed by flow distribution plate enters Bag-type dust collection device is collected cooling.
Make the modification time of powdered whiting shorter the beneficial effects of the invention are as follows function from inside to outside, modification is more filled Point, this modified powdered whiting has heat resistance, dispersiveness, can well with resin organic carrier and high polymer material It is compatible, so that electric wire toughness, brightness, plastics are stagnant hot and bending strength increases；Strengthen the fast light anti-of electric wire Aging.
