Description
Technical field
The utility model belongs to pressure vessels for the chemical industry technical field, more particularly to a kind of pressure vessels for the chemical industry wall structure.
Background technology
It is improved with the consciousness of social enviroment protection, chemical enterprise is also higher and higher to the comprehensive performance of pressure vessels for the chemical industry.Often at present
The following disadvantage of plastics pressure vessels for the chemical industry generally existing of rule：It wears no resistance, non-refractory, it is impossible to be used in holding needs the change of high-temperature stirring
Work raw material, narrow application range；Aging is easy when outdoor use, service life is short so that the waste of container is big；Plastics system is large-scale
The usual strength and stiffness of vertical vessel are poor, are easy to happen deformation after long-term use, to jeopardize container reliability, influence
Work production safety.
Utility model content
The purpose of this utility model is to provide a kind of pressure vessels for the chemical industry wall structure, safety and stability and economical and practical.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of pressure vessels for the chemical industry wall structure, describedization
Chemical container wall is three-layer composite structure, and internal layer is nucleater modified homopolypropylene plastics, and middle layer changes for inorganic material
Property polypropylene plastics, outer layer be Antioxidant-modified polypropylene plastics.
The prior art is compared, and there are following technique effects for the utility model：The internal layer being in direct contact with content is corrosion-resistant
Property good, high temperature resistant and function admirable, the intensity of middle layer increase internally, outer layer play solidification support effect, outer layer then effectively slows down
Wall aging, so as to greatly promote the performance of pressure vessels for the chemical industry, increase container dimensional, the expansion scope of application.Meanwhile three layers
Material matrix is identical, and physical and chemical performance is close, and coefficient of thermal expansion is also identical, and each layer energy effective integration, processing performance are good, can carry significantly
Rise the reliability and stability of pressure vessels for the chemical industry.
Description of the drawings
The content expressed by each attached drawing of this specification and the label in figure are briefly described below：
Fig. 1 is the schematic diagram of the utility model.
In figure：1. internal layer, 2. middle layers, 3. outer layers.
Specific implementation mode
Below in conjunction with the accompanying drawings, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
It describes in detail bright.
A kind of pressure vessels for the chemical industry wall structure, as shown in Figure 1, the pressure vessels for the chemical industry wall is three-layer composite structure, internal layer 1 is
Nucleater modified homopolypropylene plastics, middle layer 2 are inorganic material-modified polypropylene plastics, and outer layer 3 is antioxidant
Modified polypropylene plastics.Internal layer 1 uses nucleater modified homopolypropylene plastics, so that its heat resistance is greatly promoted, energy
As the stirring container under hot conditions, expand the scope of application of pressure vessels for the chemical industry；Middle layer 2 adds solid mineral material to poly- third
Alkene plastics are modified, and can significantly increase the intensity of middle layer 2, keep pressure vessels for the chemical industry wall firmer, can further increase appearance
Device size；Outer layer 3 uses Antioxidant-modified polypropylene material, and antiageing effect is good, is obviously improved its weather resistance.Due to
Inside and outside layer 1,3 does not include any solid particle, remains the good welding performance of polypropylene material, is also convenient for chemical industry appearance in this way
The processing and fabricating of device so that wall be Anywhere open welding fusion pressure depth and welding coefficient can meet demand, quality is excellent
It is good and smooth in appearance, clean and tidy.
Preferably, the internal layer 1, middle layer 2 and outer layer 3 mutually combine together.Internal layer 1, middle layer 2 and outer layer 3
Material matrix it is identical, the physical and chemical performance of layer each in this way is close, coefficient of thermal expansion is also identical, enable each layer effective integration of wall,
Mutually support effectively avoids other compounded chemical containers cylinder caused by temperature change from being layered obscission, ensures that chemical industry holds
The stability and security performance of device wall.
In production, processing is sequentially overlapped from the inside to the outside using winding shaping process, in the winding of the band-like material of each layer
In the process, band-like material is heated to hot melt state, then Wrapping formed on mold is tubulose, and the side of band-like material is made to exist
It mutually overlaps in winding process and combines together after the cooling period.Only need to last layer material strip it is Wrapping formed for tubulose and material not yet
When completely cooling, next layer of winding is carried out, just can guarantee that two layers of material of disposed adjacent mutually combines together.
Preferably, the internal layer 1 is Beta-crystalline polyacrylic plastics.The weight ratio that nucleating agent is added in the internal layer 1 is less than 8%,
The nucleating agent that internal layer 1 uses is beta nucleater.The high temperature of 110 DEG C modified of homopolypropylene material ability, friction coefficient are small,
It is avoided that solid particle and wall damage, leakage caused by wall-friction, high temperature item can be widely used in as stirring container
Hybrid reaction containing solid dielectric under part.Moreover, its shrinking percentage is also smaller than plain polypropylene material, to effectively reduce product ruler
Very little error, Improving The Quality of Products.
Preferably, the glass fibre and weight ratio that the addition of the middle layer 2 weight ratio is 5%~10% are 8%~12%
Calcium carbonate powder.Glass fibre is added in polypropylene can promote the tensile strength and heat resistance of material, it is added 8%~
12% calcium carbonate powder can then significantly improve the notch impact strength, tensile strength and bending strength of material, especially notch
Impact strength compares basis material and improves whole one times.
Preferably, the length range of the glass fibre is in 250 μm~350 μm, calcium carbonate in 1mm~3mm, diameter
The precipitated calcium carbonate of diameter 30nm~50nm, such additive can well merge with polypropylene and process facility.
It is uniformly added into that weight ratio is 8%, 250 μm~350 μm a diameter of, length is 1mm~3mm's in polypropylene plastics
Middle layer 2 is made in glass fibre and the precipitated calcium carbonate that weight ratio is 10%, a diameter of 30nm~50nm.Has this middle layer
2 container tests prove that, accommodating 100m3, proportion 1.4kg/m3Under conditions of liquid, it is resistant to 120 DEG C of high temperature；To container
Interior addition temperature is 120 DEG C, proportion 1.81.4kg/m3Solution reach 100m3When, still ensure that the stability of container wall, device
Wall does not crack, without deformation.
