Abstract
The invention discloses a method for antiseptic treatment of an inner sleeve. The method comprises the following steps of S1, grinding a steel pipe; S2, placing the ground steel pipe into an electric drying oven for preheating until the temperature reaches 230-250 DEG C with the preheating time being 30-40 min; S3, carrying out sand blasting on the steel pipe obtained after the step S2 through a sand blasting process; S4, evenly coating the inner wall and the outer wall of the steel pipe which is subjected to the sand blasting with epoxy resin and enabling the coatings on the inner wall and the outer wall of the steel pipe to be even and good in leveling property through automatic coating; and S5, carrying out curing on the coated steel pipe after coating through heating equipment which is used for carrying out preheating to 180 DEG C. According to the method, pretreatment is carried out on the steel pipe with the inner sleeve through multiple steps and measures, the corrosion resistance and the abrasion resistance of the steel pipe are improved, and the service lives of steel pipe products are prolonged.
Description
Technical field
The present invention relates to technical field of automobile components, be specifically related to a kind of inner sleeve method for anticorrosion treatment.
Background technology
The use flexibility of lining is higher, and the effect that it can play is also a lot, and lining is the base part protected equipment in short.The use of lining can reduce the wearing and tearing of equipment, vibration and noise, and has etch-proof effect.The use of lining can also facilitate the maintenance of plant equipment, the structure of simplified apparatus and manufacturing process, and existing inner metal sleeve is do not carry out pretreatment mostly, and service life is shorter.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of inner sleeve method for anticorrosion treatment, by carrying out the pretreatment of multi-step means to the steel pipe making inner sleeve, improve its anticorrosion and wearability, improve the service life of its product.
Technical scheme
Technical problem to be solved by this invention can be come to be realize by the following technical programs:
A kind of inner sleeve method for anticorrosion treatment, described the method step is as follows,
S1 polishes to steel pipe;
The steel pipe of having polished is put into Electric heat oven and is carried out preheating by S2, when temperature reaches 230 ° ~ 250 DEG C, and 30 ~ 40 minutes preheating time;
S2 step is obtained steel pipe and adopts blasting craft to carry out blasting treatment by S3; To remove the iron rust of metal surface, greasy dirt and zinc coat;
S4 epoxy resin is to the steel pipe inside and outside wall coating uniform after blasting treatment, and automatic coating makes steel pipe inside and outside wall coating uniform, good leveling property;
The rear firing equipment of S5 spraying is preheating to 180 degree and is cured the steel pipe sprayed, time is 30-40 minute, when spraying, epoxy powder is not also sintered at steel pipe inside and outside wall completely, through the pre-heat cure of 30 minutes, curing agent in epoxy resin is solidified completely, makes the coating adhesion of inside and outside wall stronger.
Described is 0.2mm-0.4mm with the thickness that epoxy powder is sprayed on steel pipe.
In described S2, preheat temperature is 240 DEG C, 35 minutes preheating time.
Compared with prior art, beneficial effect of the present invention is:
The present invention by carrying out blasting treatment to making the steel pipe of inner sleeve, to remove the iron rust of metal surface, greasy dirt and zinc coat; Then with epoxy resin to the steel pipe inside and outside wall coating uniform after blasting treatment, automatic coating makes steel pipe inside and outside wall coating uniform, good leveling property, improves its anticorrosion and wearability, improves the service life of its product.
Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of inner sleeve method for anticorrosion treatment step is as follows,
S1 polishes to steel pipe;
The steel pipe of having polished is put into Electric heat oven and is carried out preheating by S2, when temperature reaches 240 DEG C, and 35 minutes preheating time;
S2 step is obtained steel pipe and adopts blasting craft to carry out blasting treatment by S3; To remove the iron rust of metal surface, greasy dirt and zinc coat;
S4 epoxy resin is to the steel pipe inside and outside wall coating uniform after blasting treatment, and automatic coating makes steel pipe inside and outside wall coating uniform, good leveling property, and described is 0.2mm-0.4mm with the thickness that epoxy powder is sprayed on steel pipe.
The rear firing equipment of S5 spraying is preheating to 180 degree and is cured the steel pipe sprayed, time is 30-40 minute, when spraying, epoxy powder is not also sintered at steel pipe inside and outside wall completely, through the pre-heat cure of 30 minutes, curing agent in epoxy resin is solidified completely, makes the coating adhesion of inside and outside wall stronger.By carrying out blasting treatment to making the steel pipe of inner sleeve, to remove the iron rust of metal surface, greasy dirt and zinc coat; Then with epoxy resin to the steel pipe inside and outside wall coating uniform after blasting treatment, automatic coating makes steel pipe inside and outside wall coating uniform, good leveling property, improves its anticorrosion and wearability, improves the service life of its product.
It should be noted that, in this article, such as term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.
Above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
