Description
Technical field
The present invention relates to the realm of building construction, more particularly to a kind of 3D steel frames square tube inner wall anti-corrosive construction technology.
Background technology
At present, it is universal in steel frame process not focus on square tube inside anti-corrosion, application only is carried out to outside after being welded,
Inwall just has the hidden danger easily corroded by materials such as moisture, salinities after for a long time.For the house lived for consumer, one
Denier inwall is corroded, and by the load-bearing of serious main body, or even has the danger caved in, so the requirement for anticorrosion of inside pipe wall must be very
Strictly, but corresponding quality standard is also lacked without clear and definite to steel frame inside pipe wall anticorrosion process in industry.It is therefore proposed that
Specifically designed for the anticorrosion process of steel frame square tube inwall.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of 3D steel frames square tube inner wall anti-corrosive construction technology, and it overcomes
The drawbacks described above of prior art.
The technical problems to be solved by the invention are achieved through the following technical solutions：
A kind of 3D steel frames square tube inner wall anti-corrosive construction technology, comprises the following steps：
1) inside pipe wall degreasing and rust removal；
2) residue is cleared up；
3) tested using industrial endoscope；
4) inside pipe wall spray painting；
5) low temperature drying；
6) check；
7) subsequent handling is turned.
Preferably, in above-mentioned technical proposal, the step 1) reaction condition be：Sand nozzle translational speed is 0.5-3m,
Inner-walls of duct surface treatment to after processing reaches Sa2.5 grades-Sa3 grades.
Preferably, in above-mentioned technical proposal, the step 2) cleaning residue is specially：Filled in pipe using sponge or gauze
Portion, is then got with high pressure nitrogen, is cleaned out remaining abrasive material and iron filings with interior wall friction by sponge.
Preferably, in above-mentioned technical proposal, the step 3) inspection when use industrial endoscope, sprayed again if unqualified
Sand or cleaning residue.
Preferably, in above-mentioned technical proposal, the step 4) inside pipe wall spray painting use one-component antirust paint.
Preferably, in above-mentioned technical proposal, the step 5) reaction condition be：50-90 DEG C of drying temperature, drying time
10-30min。
The present invention has the advantages that：
3D steel frames square tube inner wall anti-corrosive construction technology of the invention, anticorrosion process compensate for the country in building trade in pipe
Blank in the pipe of this field of steel construction in terms of anti-corrosion, protection and building useful life longevity to later steel construction are served very
Important effect, effectively lifts resource utilization, maximizes the use value of product, is worth promoting.
Brief description of the drawings
Fig. 1 is the flow chart according to 3D steel frames square tube inner wall anti-corrosive construction technology of the invention.
Specific embodiment
Specific embodiment of the invention is described in detail below, in order to further understand the present invention.
The special sand-blasting machine of inside pipe wall (can on request customize or select conventional existing machine) of the invention, routine are existing
Industrial endoscope, inside pipe wall paint spraying machine special (can on request customize or select conventional existing machine).
Fig. 1 is the flow chart according to 3D steel frames square tube inner wall anti-corrosive construction technology of the invention.As shown in the figure：
A kind of 3D steel frames square tube inner wall anti-corrosive construction technology, comprises the following steps：
1) inside pipe wall degreasing and rust removal：Sand nozzle translational speed is determined according to corrosion situation during inside pipe wall degreasing and rust removal, typically
0.5-3 meters can arbitrarily be adjusted, and inner-walls of duct is surface-treated up to Sa2.5 grades-Sa3 grades.
2) residue is cleared up：Cleaning residue can be used sponge or gauze to fill in inside pipe, it is desirable to which compacted mass can be fully contacted
Inwall, is then got with high pressure nitrogen, is cleaned out remaining abrasive material and iron filings with interior wall friction by sponge.
3) check：During inspection use industrial endoscope, when unqualified again sandblasting or cleaning residue.
4) inside pipe wall spray painting：Inside pipe wall paints using (can also be selected by customer requirement) by one-component antirust paint,
It is required that without drain spray, slight sagging and orange peel, weatherability is not Qiang Zhiyaoqiud.
5) low temperature drying：Drying temperature is controlled in 50-90 DEG C, time 10-30min.
6) check.
7) subsequent handling is turned.
Aforesaid operations will be carried out in strict accordance with quality control, the standard of execution, system management, product standard, quality planning
Quality management and control.
With reference to relevant criterion
The oil removing degree method of inspection before GB/T 13312-1991 steel and iron parts applications
Steel surface rusting grade and derusting grade before GB/T 8923-1988 applications
The evaluation of steel surface roughness grade number before GB/T 13288-1991 applications
3D steel frames square tube inner wall anti-corrosive construction technology of the invention, anticorrosion process compensate for the country in building trade in pipe
Blank in the pipe of this field of steel construction in terms of anti-corrosion, protection and building useful life longevity to later steel construction are served very
Important effect, effectively lifts resource utilization, maximizes the use value of product, is worth promoting.
Although the present invention is disclosed as above with embodiment, so it is not intended to limit the present invention, any people in the art
Member, without departing from the spirit and scope of the present invention, can make a variety of selections and modification, therefore protection model of the invention
Enclose and limited by claims and its equivalents.
