Abstract
The utility model discloses an inner bushing used as a lining of anti-corrosion equipment, which comprises a fluoroplastic lining. The outer surface of the lining is provided with a glass fiber cloth layer; and a bonding layer is arranged between the lining and the glass fiber cloth layer. The inner bushing of the utility model has low process cost, and good liner tightening firmness, and is non-toxic.
Description
Technical field
The utility model relates to a kind of neck bush that is used for anticorrosion equipment as lining.
Background technology
Various countries, the world today are in the corrosion-resistant field engineering is used, and as various large-scale corrosion-resistant equipment that need such as various pipelines, tower, stills, the main liner made from polytetrafluoroethylene (PTFE) is as the corrosion-resistant lining.But because the heat expansion and the cold flow properties of polytetrafluoroethylene (PTFE), the phenomenon of pine lining at inner-walls of duct generally can appear in polytetrafluoroethylene (PTFE), and therefore, engineering circle is being explored the method that how the fluoroplastics liner is tightly served as a contrast at the anticorrosion equipment inwall always.Use comparatively common method to be at present, at first the appearance of fluoroplastics liner is carried out deoxidation treatment, by adhesive the fluoroplastics liner is tightly served as a contrast at the anticorrosion equipment inwall then.But this method is owing to need carry out deoxidation, and cost is high, and toxic, and the fastness of tight lining also is difficult to reach the special requirement of some engineering.
The utility model content
At above the deficiencies in the prior art, the utility model proposes a kind of neck bush as the anticorrosion equipment lining, the technology cost is low, avirulence, and it is fine tightly to serve as a contrast fastness.
Neck bush as the anticorrosion equipment lining of the present utility model includes a fluoroplastics liner, has a glass fibre layer of cloth at the outer surface of liner, has a tack coat between liner and glass fibre layer of cloth.
As preferably, described tack coat is made for the solubility polytetrafluoroethylmaterial material.
Adopt neck bush of the present utility model, after the high temperature heating, the sintering that its glass fibre layer of cloth can be firm is on the surface of fluoroplastics liner, the base that formation is used for boning does not need deoxidation treatment, and overall process does not have toxicity, the technology cost is low, can reach the firm effect of well tight lining.
Description of drawings
Described in detail below in conjunction with structure, feature, principle, use operation and the performance of accompanying drawing neck bush of the present utility model.
Fig. 1 is the structure cut-away view of the utility model one preferred embodiment.
The specific embodiment
Please refer to Fig. 1, be the generalized section of a preferred embodiment of the utility model neck bush.
Neck bush as the anticorrosion equipment lining of the present utility model, include a fluoroplastics liner 1, outer surface at liner 1 has a glass fibre layer of cloth 3, have a tack coat 2 between liner 1 and glass fibre layer of cloth 3, this tack coat 2 is used for making when high temperature heats glass fibre layer of cloth 3 and liner 1 to bond together closely.This tack coat 2 is that the solubility polytetrafluoroethylmaterial material is made.
Will be with neck bush liner of the present utility model during to anticorrosion equipment, put above-mentioned neck bush into high temperature furnace, heat, be incubated 2～3 hours to 350 ℃～365 ℃, then with high temperature furnace cooling, this moment glass fibre layer of cloth 3 securely sintering on the surface of liner 1 and form base in order to bonding; During bonding, select suitable adhesive for use, the bonding base adhesive solidification that will form by adhesive is at the inwall of anticorrosion equipment then, and liner is at the anticorrosion equipment inwall firmly, closely thereby guarantee neck bush, can not come off easily or loosening.
As seen comprehensive above-mentioned, neck bush of the present utility model is through behind the high-temperature heating, its glass fibre layer of cloth firmly sintering forms the bonding base on the surface of fluoroplastics liner, do not need deoxidation treatment, overall process does not have toxicity, and process costs is low, can reach the well firm effect of tight lining.
Claims (2)
1. the neck bush as the anticorrosion equipment lining includes a fluoroplastics liner, it is characterized in that, has a glass fibre layer of cloth at the outer surface of liner, has a tack coat between liner and glass fibre layer of cloth.
