Description
Technical field
The present invention relates to cable duct tube field, in particular it relates to a kind of production technology of polyvinyl cement cable duct tube.
Background technology
Polyvinyl cement conduit be cement, vinylon fibre and water are reconciled in proportion, mixed, is molded, conserve after make cement hard
Change and by it is fiber gelatinized together and formed artificial stone material.
Polyvinyl cement conduit by its fiber and cement stirring when amount of water number be divided into dry method, semidry method and wet method three
Kind production technology.Dry production is with a small amount of water（About 15-20% or so）Fiber and cement mixing and stirring is uniform, utilize
Extruding, punch forming.Semidry method is plus 40% or so water stirs cement and fiber, using slip casting method and gunite into
Type.Although equipment is simpler when above two method is molded, certain shortcoming be present, dry technology for production raw material mixes not
Uniformly, fiber is in three-dimensional arrangement, and utilization rate is low, and Semi-dry process process of fiber is in space disordered arrangements, the utilization rate of fiber
Low, the density of product is low, low intensity, and therefore, above two production technology can be only applied to some specific cement components.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of production technology of polyvinyl cement cable duct tube, existing to overcome
The problem of product density caused by some polyvinyl pipe of cement preparation technologies is low, low intensity.
Technical scheme is used by the present invention solves the above problems：The production technology of polyvinyl cement cable duct tube, including
Following steps：
1）, slurry preparation：Pipe raw material and water are mixed into pulp storage tank in proportion, stirred, the pipe raw material bag
Include cement, vinylon fibre；
2）, slurry stirring：Slurry after pulp storage tank stirs overflows to the first net cage successively, the second net cage is stirred；
3）, slurry copies and takes：Slurry in second net cage is copied through net wheel to be got on felt；
4）, slurry dewatering：Slurry on felt is dehydrated through vaccum bench；
5）, pressure forming：After vaccum bench is dehydrated, mandrel is pressed on breast roll by pressured rubber roll, realizes pressure forming；
6）, the conduit after pressure forming is stripped, cuts two, maintenance, initial set, rest, examine and form finished product successively.
The preparation of existing polyvinyl pipe of cement is typically to use dry method and semidry method, and dry production is with a small amount of water（About
For 15-20% or so）Fiber and cement mixing and stirring is uniform, utilize extruding, punch forming.Semidry method be plus 40% or so water
Cement and fiber are stirred, are molded using slip casting method and gunite；Above two method be easily caused raw material mixing it is uneven,
The spatial arrangement of fiber is mixed and disorderly so that the utilization rate of fiber is low, and then causes product density low, low intensity.
The present invention uses wet process technique, and wet process technique specifically refers to add greatly after pipe raw material is well mixed
The water of amount（About the 98% of pipe raw material）Dilution is loosened, and a certain proportion of slurry is made, and is pressed after repeatedly stirring on special equipment
Power roll-forming.
Detailed process prepared by slurry of the present invention is：A certain proportion of cement and vinylon fibre starting material with water are rushed
Wash, dilute, wait and pulp storage tank is squeezed into after fiber reinforced cement composite be stirred to prevent water mud from precipitating, and mixture is all homogenized, make
Solid fraction fiber etc. arranges into texture；Diluted using substantial amounts of water and mix cement and vinylon fibre, be on the one hand advantageous to the fast of cement
Speed mixes, on the other hand, it is ensured that the viscosity of the cement of mixing is smaller, is advantageous to being uniformly distributed for vinylon fibre, improves fiber
Space availability ratio, the polyvinyl pipe of cement for preparation high density, high intensity carry out sufficient basis.
The detailed process of slurry stirring is：The slurry of pulp storage tank after first time stirs automatic overflow to the first net
Case, the second net cage carry out second and third stirring respectively, and its main function is to prevent cement from precipitating, and make vinylon fibre arrangement side
Tend to be collectively aligned to major part, and ensure the second net cage on the water surface to the lower water surface one section of height inner flow surface in same direction
Upper stirring, be advantageous to net wheel and copy take material, if the direction of the water surface stirring in the second net cage is chaotic, is easily caused net wheel and copies feeding
Resistance during slurry is larger, thus repeatedly stirring improves the arrangement rate in the same direction of vinylon fibre, can effectively avoid in the second net cage
The problem of direction confusion of water surface stirring.
The slurry copies the detailed process taken：Under the driving of motor, net wheel, breast roll rotate, and the net wheel is specifically
Refer to it is a kind of can pick slurry and slurry is copied to the roller frame for drawing felt, using breast roll as driving wheel, auxiliary roller is driven pulley, band
Dynamic felt transmission（The kind of drive is similar to transmission belt）, the net wheel of rotation picks the slurry in the second net cage, when felt revolves around auxiliary roller
When turning, the slurry on net wheel, which is equably copied, to be taken on felt, enables slurry to be uniformly adhered to hair using taking technique is copied
On cloth, the uniformity metric of the Cement fibre pipe of preparation is improved, and then improve intensity.
The breast roll is the mould of Cement fibre pipe, and felt is under the effect of the pressure by the water after dehydration after vacuum dehydration
Mud and vinylon fibre mixture are compressed on mandrel, realize pressure forming, the pressure is will by hydraulic-driven rubber roll, rubber roll
Cement and vinylon fibre are compressed on mandrel realization in layer.
Due to the product in shaping with certain line pressure, in two dimension row after vinylon fibre and cement plus water stirring
Row, so the main solidity of tubing after rolling is very high, cement and it is fiber gelatinized after, there is very high rupture strength and compression strength,
And there are good barrier properties.Tubing after resting has very high heat resistance and chemical stability, have insulation, sound insulation, every
The features such as hot, shockproof and anti-corrosion.Because its primary raw material is cement, so with very high water imbibition and good machining
Property, it can drill, turning, polishing greatly increases its use value.
The present invention prepares polyvinyl cement cable duct tube by using copying taking technique, and the stage of slurry stirring is prepared in slurry and is made
Obtain cement and vinylon fibre be well mixed, and make it that vinylon fibre is spatially evenly distributed, improve vinylon fibre utilization rate,
