Sealing automatic production line.
Background technique
Most domestic sealant producer is used in kneader, high speed disperser and heating stirring kettle substantially poly-
Close object and powder and be pre-mixed heating water removal, then cool in planetary mixer be added auxiliary agent and colorant etc. take off it is low after with big
It is dispensed again after bucket packaging.
Fraction producer is sealed glue production using twin-screw and static mixer at present.Twin-screw extrusion is the most frequently used
One of polymer processing method, according to the difference in two screw rod relative rotation directions, be divided into rotating Vortex and counter rotating two
Major class.Heterodromy double-screw extruder, which squeezes out, to be stablized, and the demanding product of the pair cross-sections size such as tubing, profile is mainly used for
Extrusion molding；Heterodromy double-screw extruder, which squeezes out, to be stablized, and the demanding system of the pair cross-sections size such as tubing, profile is mainly used for
The extrusion molding of product.And the extrusion system overwhelming majority of parallel dual-screw extruding machine uses modular structure, each each spiral shell of barrel assembly
Rod element can meet specific mixing process to the spy of conveying, melting, mixing, devolatilization, homogenizing etc. by transformation combination
It is different to require.
The shortcomings that background technique:
Country's twin-screw is divided into parallel dual-screw extruding machine and counter rotation twin screw extruder at present.Incongruous double screw is divided into inward turning
Turn and rotate outward two kinds of situations, incorgruous screw machine is fewer because material be easy between the radial clearance of two screw rods,
The accumulation easy to form of the upper and lower of two screw rods not only influences processability to influence the ability that screw rod receives feeder material
Can, it is also easy to form situations such as building bridge and causing " card screw rod "；Secondly the material of two screw rod radial clearances is rotating inward
Under active force, two screw rods can be pressed to machine barrel to two sides by reaction force, this can accelerate to wear with machine barrel.
And parallel dual-screw is divided into clockwise and anticlockwise, relatively common is to rotate clockwise, and screw flight is to the right
Rotation, two screw flight combinations, directions are consistent with shape；After material enters twin-screw by side feeder, by conveying
Screw thread conveying and pressurization reach kneading portion and reach mixed effect with machine barrel screw channel wall mutual extrusion in the case where mediating threaded function；
However the lead of conveying screw thread and the revolving speed of screw rod determine the additional amount of material, mediate the quantity of screw thread and the stop of material
Time determines the dispersion effect of powder in the polymer.Too fast revolving speed will lead to subtracting for dispersion effect when therefore improving yield
It is weak, inevitably result in the increase of the energy consumptions such as increase and barrel heat heating, the refrigerator cooling and motor rotation of spiro rod length.
