Abstract
The utility model provides an anti-corrosion PE composite polytetrafluoroethylene gasket. The gasket is characterized by comprising a polytetrafluoroethylene film and a PE foaming gasket. Due to the fact that the polytetrafluoroethylene film and the PE foaming gasket are glued through glue, and therefore the gasket has the advantages of the high anti-corrosion performance of a polytetrafluoroethylene gasket and the advantages of possessing heat-resistant stability and soft shape and being easily matched with a packing bottle of the PE foaming gasket. Compared with the using performance of a rubber composite polytetrafluoroethylene gasket, the anti-corrosion PE composite polytetrafluoroethylene gasket has advantages of high elasticity, high anti-corrosion performance and good sealing performance of the rubber composite polytetrafluoroethylene gasket, and can avoid the negative phenomenon that the rubber composite polytetrafluoroethylene gasket is easily affected by storage temperature, and the shape of the rubber composite polytetrafluoroethylene gasket greatly changes.
Description
Technical field
The utility model relates to a kind of withstanding corrosion pad of depositing the bottle of chemical material.
Background technology
Because the kind of chemical reagent is more, character differs, and selecting of its packing is the difficult problem that chemical reagent manufacturer faces always.And as directly contacting with product, as universaling packing first the supporting gasket seal playing an important role, very difficultly especially select a kind of excellent performance, highly versatile, curability is better and corrosion stability is high material from numerous making materials.At present, in the packing of chemical reagent, conventional gasket seal is mainly in the majority with the pad of teflon gasket and these two kinds of materials of PE foamed spacer, in addition at home and external minority producer, also has the pad that adopts rubber to cover polytetrafluoroethylene material.
The good decay resistance of teflon gasket is usually used in the stronger chemical reagent of corrosive property packing it, but teflon gasket is easy-cold flow after pressurized, the characteristic of easy creep after being heated, and quality is compared with hard its sealing property that easily affects without good elasticity.PE foamed spacer has good heat-resistant stability, rebound resilience and anticorrosive and ageing-resistant advantage, and by a large amount of packings for chemical reagent, but be subject to the low impact of self material corrosion resistance, the kinds of goods stronger to corrosive property, are easily corroded and cause packing reagent and reveal.And rubber covers polytetrafluoroethylene film gasket owing to having good elasticity and higher corrosion stability, can overcome the shortcoming of above two kinds of pads, it is softer that but rubber covers the material of main base material rubber of polytetrafluoroethylene film gasket, and easy temperature influence and being out of shape, thereby easily cause gap leakage, therefore have relatively high expectations to depositing with environment for use.Though thereby these three kinds of pads respectively have advantage, be subject to the impact of environment for use and storage condition and can not be packed general employing by chemical reagent simultaneously.
Summary of the invention
This uses novel object to be to provide a kind of anti-corrosion pad that has stronger anticorrosive property and good leak tightness and can large area packing use.
To achieve the above object, the technical solution of the utility model is to provide a kind of withstanding corrosion PE ptfe composite pad, it is characterized in that, comprise poly tetrafluoroethylene and PE (polyethylene) foamed spacer, described poly tetrafluoroethylene and PE foamed spacer are bonded together by colloid.
Preferably, the PE overlay film that described PE foamed spacer comprises PE foamed material layer and is located at the upper and lower both sides of PE foamed material layer.
Preferably, described poly tetrafluoroethylene and PE foamed spacer are all disc.
Preferably, described poly tetrafluoroethylene and PE foamed spacer are located in the spacer groove in packaging cover, and poly tetrafluoroethylene is positioned at the outside of PE foamed spacer.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is owing to having adopted two kinds of materials of poly tetrafluoroethylene and PE foamed spacer bonding by jelly, thereby possessed the high-intensity corrosion stability of teflon gasket, heat-resistant stability and the shape of PE foamed spacer are softer, easily and Packaging Bottle form the intact advantage such as agree with.The poor difficult use of corrosion stability that punching has balanced out PE foamed spacer is on the stronger chemical reagent of corrosive property, and pure teflon gasket material is harder, the poor and easy temperature influence of elasticity and be difficult for using this two classes shortcoming in glass bottle class packing.Compare with rubber combined teflon gasket usability simultaneously, withstanding corrosion PE ptfe composite pad of the present utility model has not only had high resiliency, corrosion stability and the good advantages such as leak tightness of rubber combined teflon gasket, has also avoided rubber combined teflon gasket to be subject to storage temperature impact and this bad phenomenon of the larger variation of body generation.Owing to having there is every advantage of above discussion, make this pad there is reagent and pack spendable popularity.From then on reagent manufacturer is except the special reagent of fraction, all can adopt this pad to encapsulate, procurement item and the inventory cost of reagent manufacturer have been simplified, optimized packaging scheme, and can avoid contacting of reagent and outside air completely, reagent can long term seal be preserved and the transporting safely of long distance.
Accompanying drawing explanation
Fig. 1 is the square section schematic diagram of withstanding corrosion PE ptfe composite pad.
Fig. 2 is the use schematic diagram of withstanding corrosion PE ptfe composite pad.
The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1, withstanding corrosion PE ptfe composite pad of the present utility model is comprised of poly tetrafluoroethylene 3, PE foamed spacer and colloid 4, poly tetrafluoroethylene 3 is made by polytetrafluoroethylmaterial material, described PE foamed spacer comprises the PE foamed material layer 1 of being made by PE foam material technique and the PE overlay film 2 of being located at PE foamed material layer both sides Shang Xia 1, and described PE foamed material layer 1 is low foaming PE.Adopt three-layer co-extruded mode to make PE foamed spacer.Between poly tetrafluoroethylene 3 and PE overlay film 2, by colloid 4, poly tetrafluoroethylene 3 and PE foamed spacer are bonded together, form withstanding corrosion PE ptfe composite pad.Described poly tetrafluoroethylene 3 and PE foamed spacer are all disc.
As shown in Figure 2, before use, first by withstanding corrosion PE ptfe composite pad of the present utility model according to PE overlay film 2 in inner side and with the interior side contacts of matching cap 6, poly tetrafluoroethylene 3 is in outside and the mode contacting with packaging product, in the spacer groove that is filled into matching used packaging cover 6 by manual operation or professional equipment, also can in the process of filling, utilize spot gluing equipment that withstanding corrosion PE ptfe composite pad of the present utility model is bonded in the spacer groove of packaging cover 6.Then by supporting, there is the packaging cover 6 of this pad utilize specialized equipment or be manually arranged in Packaging Bottle and screw, utilizing while manually screwing, can manually be threaded to can not turn time, thereby utilize the about 90-degree rotation of cage plate cw sealed package completely.Poly tetrafluoroethylene 3 and PE overlay film 2 when packaging cover 6 screws, the backward interior contraction of pressurized and exerting pressure to PE foamed material layer 1, the inside elastic shrinkage of PE foamed material layer 1 pressurized, forms the depression 5 of agreeing with bottleneck, just can play the effect of elastic seal completely.
