Description
Technical field
The invention belongs to the technical field of cast iron pipe product processes.More particularly it relates to a kind of cast iron pipe
Inner lining structure.In addition, the invention further relates to the production technology of the inner lining structure.
Background technology
At present, there is following defect in the liner of cast iron pipe product：
1st, existing inner lining process imperfection, partial tube is present from drum phenomenon；
2nd, liner primer proportioning is referring especially to old production technology：Cement：801 glue=(1：3), portion of material and technique ginseng
Number can not meet production requirement；
3rd, primer influences strength of cement mortar with specific mass；
4th, the processing compound of primer is adjusted, reduction pipe fitting liner is from drum.
The content of the invention
The present invention provides a kind of cast iron pipe inner lining structure, and the purpose is to reduce the production cost of inner lining structure.
To achieve these goals, the technical scheme taken of the present invention is：
The cast iron pipe inner lining structure of the present invention, is the setting cement lining screed on pipe fitting inner wall, in described pipe fitting
One layer of primer layer is set between inwall and cement lining screed, and described primer layer is formed with water and cement, the water
Quality proportioning with cement is 1: 4.
The thickness of described primer layer is 0.1~0.5mm.
Described cement lining screed is formed with cement, water and 801 glue；The matter of described cement, water and 801 glue
Amount proportioning is 1: 1.3: 0.144.
In order to realize with above-mentioned technical proposal identical goal of the invention, present invention also offers in above-described cast iron pipe
The production technology of lining structure, its technical scheme is：
When described primer layer is not dry, the brushing of cement lining screed is carried out.
Before described primer layer brushing, pipe fitting inner wall is cleared up, prevents that pipe fitting inner wall from locally getting rusty influence liner
Quality.
After described cement lining screed brushing, press spoon to carry out surface to cement lining screed using circular arc and put down
Whole, consolidation processing, while detecting the thickness of cement lining screed.
Described circular arc pressure spoon carries out surfacing, consolidation processing using steel pressure spoon.
The present invention uses above-mentioned technical proposal, directly reduces the production cost of cast iron pipe liner；Reduce making for 801 glue
With improving the liner feature of environmental protection；Production process is physically easier to perform；Cement lining leafing drum rate is reduced, product quality is improved.
Brief description of the drawings
Content shown in accompanying drawing and the mark in figure are briefly described as follows
Fig. 1 is structural representation of the invention.
Marked in figure：
1st, pipe fitting inner wall, 2, cement lining screed, 3, primer layer.
Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical scheme
Solution.
The structure of the present invention, is a kind of cast iron pipe inner lining structure as shown in Figure 1, is to be set on pipe fitting inner wall 1 in cement
Serve as a contrast screed 2.The present invention is to improve the technological measure of pipe fitting cement lining quality.
In order to solve the problem of prior art is present and overcome its defect, the hair of the production cost of reduction inner lining structure is realized
Improving eyesight, the technical scheme that the present invention takes is：
As shown in figure 1, the cast iron pipe inner lining structure of the present invention, described pipe fitting inner wall 1 and cement lining screed 2 it
Between one layer of primer layer 3 is set, described primer layer 3 forms from water and cement witing, and the quality proportioning of the water and cement is 1:
4。
Specific method is：Using water and cement, cement primer is configured, the configuration of 801 glue and cement is substituted；Carry out primer work
Skill is tested, and determines the practical parameter that cement is matched with water；Carry out brushing pass experiment, on the premise of quality is ensured, will brush
Twice of primer is changed to one time, improves labor productivity.
Twice of primer is changed to one time, first wife's ratio：Cement: 801 glue=1: 2, it is changed to：Water: cement=1: 4；While liner
Before primer, pipe fitting inner wall is cleared up, prevents that inwall from locally getting rusty influence lining quality.
The thickness of described primer layer 3 is 0.1~0.5mm.
Described cement lining screed 2 is formed with cement, water and 801 glue；Described cement, water and 801 glue
Quality proportioning is 1: 1.3: 0.144.
When described primer layer 3 is not dry, the brushing of cement lining screed 2 is carried out.
Before described primer layer 3 is brushed, pipe fitting inner wall 1 is cleared up, prevents pipe fitting inner wall 1 is local from getting rusty in influence
Matrix amount.
After described cement lining screed 2 is brushed, press spoon to carry out surface to cement lining screed 2 using circular arc and put down
Whole, consolidation processing, while detecting the thickness of cement lining screed 2.
Described circular arc pressure spoon carries out surfacing, consolidation processing using steel pressure spoon.
It is using the beneficial effect of above-mentioned technical proposal：
1st, the production cost of liner is directly reduced；
2nd, the use of 801 glue is reduced, the liner feature of environmental protection is improved；
3rd, workman is easily operated；
4th, cement is reduced from drum rate.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
