Description
Technical field
The present invention relates to a kind of industrial rubber roll.
Background technique
Existing rubber roller for industry be with metal or other materials for core, cover the roll goods that rubber is made through sulfuration outward.This rubber roller for industry due to wear-resisting property and resistance to heat bad, in harsh industrial environment, using one, that burn into occurs is aging, and mechanical property is poor, and working life is shorter.
Chinese invention patent (application number: 201210351099, the applying date: on September 20th, 2012) disclose a kind of rubber roller for industry, comprise metal-cored, describedly metal-coredly be coated with outer layer glue, described outer layer glue and metal-cored between be provided with hard glue-line, described outer layer glue outer wall is fitted with polytetrafluoroethylene film layer.This patent is only arrange polytetrafluoroethylene film layer at roll surfaces, polytetrafluoroethylene film laminating closes on outer layer glue, the thickness low LCL of polytetrafluoroethylene film layer easily causes peeling off, additionally by the difficulty of processing arranging multilayer outer layer glue and hard glue-line and too increase product.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of teflon rubber roll, this rubber roll has the features such as strong acid-base-resisting, high-low temperature resistant (± 200 DEG C), ageing-resistant long service life.
In order to realize above-mentioned object, present invention employs following technological scheme:
Teflon rubber roll, this rubber roll comprises roll body and metal mandrel, and roll body adopts the cylinder-shaped sleeve of teflon material, and the wall thickness of sleeve pipe is at 10 ~ 100mm, described metal mandrel to be located in sleeve pipe and to fix with sleeve pipe, is respectively equipped with spindle nose at the two ends of plug.
As preferably, the wall thickness of described sleeve pipe is at 20 ~ 50mm.
As preferably, the surface of described metal mandrel is axially arranged with sword groove tooth, and metal mandrel and sleeve pipe are tightly fixed by sword groove tooth.
As preferably, described metal mandrel comprises metal tube and connection end, and metal tube is set in sleeve pipe, and connection end is set in the two ends of metal tube, and welds mutually with metal tube inwall, and described spindle nose is arranged on connection end.
As preferably, the outer surface of described connection end is arranged with teflon cover, and the end face of metal tube closed by teflon cover, and the end face of teflon cover is concordant with the end face of sleeve pipe, and welds mutually with box face.
As preferably, the wall thickness of described metal tube is 10 ~ 40mm.
As preferably, described teflon sleeve wall thickness is 10 ~ 30mm.
The present invention is owing to have employed above technological scheme, and product antiseptic property is powerful, can use not aging for a long time, do not corrode in any acid-base solution, and indeformable, superpower high and low temperature resistance, normally can use under ± 200 DEG C of environment.It is short for working life that this product solves traditional rubber roll, the situation of easy damaged.Rubber roll of the present invention can be widely used in the industries such as each chemical industry, papermaking, smelting, printing, has the feature such as strong acid-base-resisting, ageing-resistant long service life.Particularly in the corrosive environments such as strong acid and strong base, working life can reach the 12-24 month.Overcome general rubber roll less than the situation of 60 days, greatly to enhance productivity working life in corrosive environment, saved cost of production, added the performance of enterprises etc.Traditional product, be that raw material makes with rubber, corrosion resistance is poor, not wear-resisting, service time only has one month, this cost of goods manufactured is the same with traditional product, but can reach 1 year the service time of this product, greatly reduces the cost of production of rubber roll applying unit, and the contaminativity of rubber is large, during this product uses, contamination-free produces.
Rubber roll of the present invention can be widely used in the industries such as chemical industry, smelting, printing, overcomes traditional rubber roll short for working life, and easily the shortcoming such as aging, greatly reduces the cost of production of rubber roll applying unit, be especially applicable to papermaking, zinc-plated, the industries such as pickling.Therefore, possess energy-saving and cost-reducing and high performance product as one, market prospects are boundless.
