Abstract
The utility model discloses an anti-corrosion bolt, belongs to clamping pieces, and particularly relates to a corrosion resistant bolt. The bolt is composed of two parts, namely a bolt functional body and an ultra-high molecular weight polyethylene coating, wherein a common bolt structure is adopted in the bolt functional body, the ultra-high molecular weight polyethylene coating is covered on the whole outer surface of the bolt functional body, and the thickness of the ultra-high molecular weight polyethylene coating is 0.08-0.1 millimeter. The anti-corrosion bolt has the advantages that not only does the bolt have the intensity and the function of a common bolt, but also is the ultra-high molecular weight polyethylene coating resistant to the corrosion of acid, alkali and salt, does not rust forever and does not affect the assembling and the disassembling of the bolt when in use, and the anti-corrosion bolt is easy to manufacture, low in production cost and long in service life.
Description
Technical field
The utility model belongs to the fastening piece class, specifically a kind of corrosion resistant bolt.
Background technique
Bolt is a kind of modal fastening piece, is applied to the every field of human being's production, life.In the using process, often can be serious because of bolt corrosion, make troubles for dismounting and maintenance.Particularly in Chemical Manufacture and the ocean environment, the corrosion of bolt is more serious, threatens sometimes the safe operation of equipment.At present, modal anti-corrosion method is zinc-plated or the Dacroment processing.Though zinc-plated have certain rotproofness, it is dangerous that zinc-plated rear bolt has certain hydrogen embrittlement, and do not have an acid resistance.Dacroment is processed, and does not have equally acid resistance, and on the high side, only has privileged sites to use, and does not have general applicability.The bolt that adopts the Teflon material is also arranged, but expensive.Therefore, develop a kind of plain bolt intensity that both had, the again various acid of ability, alkali, salt corrosion, and also the low bolt of cost is that situation is required.
Summary of the invention
The purpose of this utility model provides a kind of Novel bolt that intensity is high, corrosion-resistant, making is simple, cost is low that has.
The technical solution of the utility model is: this bolt is comprised of bolt function body and ultra-high molecular weight polyethylene coating two-part, wherein the bolt function body adopts the plain bolt structure, the ultra-high molecular weight polyethylene coating is covered in whole outer surfaces of bolt function body, and its thickness is 0.08-0.1 mm.
The beneficial effects of the utility model: this bolt not only has intensity and the function of plain bolt, the ultra-high molecular weight polyethylene coating can also acid-and base-resisting, the corrosion of salt, and Never-rusty does not affect the bolt installation and removal in the use, have make simple, cost is low, the characteristics of long service life.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model is comprised of bolt function body 1 and ultra-high molecular weight polyethylene coating 2 two-part, and wherein bolt function body 1 adopts the plain bolt structure, requires any surface finish, behind the treatment process of removing contamination, places the spraying operation room.Superhigh molecular weight polyethylene material is covered in whole outer surfaces of bolt function body 1 through spraying process, form layer protective layer, and the thickness of control ultra-high molecular weight polyethylene coating 2 is that 0.08-0.1 mm can reach the best protection effect.This bolt not only has intensity and the function of plain bolt, and the ultra-high molecular weight polyethylene coating can also acid-and base-resisting, the corrosion of salt, and Never-rusty does not affect the bolt installation and removal in the use, have make simple, cost is low, the characteristics of long service life.
