Detailed Description

Exemplary embodiments of the present invention will hereinafter be described in detail with reference to the accompanying drawings, wherein like or similar reference numerals denote like or similar elements. Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in schematic form in order to simplify the drawing.

Industrial bandages are distinguished from medical bandages in that they are an adhesive tape assembly for repairing damaged or leaking points, and a typical application thereof is for repairing pipes or cables. The industrial band-aid can be used for the maintenance and the prevention protection of various pipelines, cables and cable joints in various industrial and mining enterprises such as ships, mines, power plants, machinery, chemical engineering and the like, particularly in mining application, is used for the maintenance and the emergency repair of the pipelines, the cable joints and the cables, is used for the armor protection of joint parts, the repair of power cable sheaths and the outer protection of cable intermediate joints in power cables, is used for the quick leakage-proof repair of various pipeline pipelines, can be used for the armor protection layer of the pipelines, and can greatly reduce various losses and the first-aid repair cost caused by the leakage of various pipelines and the abrasion of the pipelines.

The adhesive tape of the industrial band-aid is typically compounded by adopting a high polymer material and an inorganic material, wherein the high polymer material is mainly high-performance polyurethane and other additives, and the inorganic material is mainly obtained by weaving and sintering high-performance and high-quality glass fibers. In one particular example, the tape 11 is constructed of two layers of material, including a substrate 111 and a cured layer 112 disposed on the substrate 111, as shown in FIG. 5. One example of the substrate 111 is alkali-free or low-alkali glass fiber cloth, one example of the cured layer 112 is flame-retardant polyurethane prepolymer mixture, the cured layer is coated on the substrate to obtain an adhesive tape, and then the adhesive tape is vacuum-packed to obtain an industrial adhesive bandage product to be used.

The instructions for the use of industrial adhesive bandage products prescribe the operating specifications for adhesive tape application, and recommend strict adherence to the operating specifications, and operation according to the operating specifications can greatly improve the pressure resistance and mechanical properties of the products, but in practical application, the execution of the operating specifications depends on the skill level of constructors, and a new laying method and auxiliary technical means are expected to be provided to assist the operators in executing the operating specifications for construction.

The method of laying the industrial adhesive bandage of the present invention is based on the above-mentioned type of industrial adhesive bandage, which is a water-curable type of industrial adhesive bandage, and in its laying process, it is preferable to bring the tape into contact with water, for example, by immersing in water, and then take out, remove excess moisture, and perform the sticking. It is important that the tape contacts water and removes excess water and that the tape be accurately lapped as required, and furthermore, at the start of winding, the tape is taken out of the bag and held by the operator all the time, and if foreign particles are present on the glove while holding, they are likely to stick to the tape, and the adhesion of the contaminated tape is significantly reduced, which affects the pressure resistance of the industrial band-aid, and in particular, the glove is more likely to be contaminated if the operator needs to press the pipe with his hand during operation. The following is a detailed description of the effects that the above three operation methods may have if the execution is defective.

Firstly, it is easy to understand that a contaminated adhesive tape can reduce the adhesiveness of the adhesive tape, thereby affecting the pressure resistance of the industrial band-aid; secondly, the industrial band-aid is a water-curing product, the curing time of the industrial band-aid is related to the amount of water absorption and the volatilization of water contained in the industrial band-aid, after the adhesive tape is taken out of the bag body and water is squeezed out, the adhesive tape is exposed in the environment during the operation process, the water is easy to volatilize, the curing time is fast, an operator needs certain operation time for pasting the pipeline, the pipeline needs to be repeatedly pasted for many times in some occasions, more time is needed, and the problem that the adhesive tape is cured before the pasting is finished can exist; thirdly, in the step of removing the excess water in the adhesive tape, the squeezing is performed by hands, the squeezing is not uniform, the removal of water is not sufficient, and the adhesion uniformity of the adhesive tape is affected; fourth, it is unreliable to obtain the desired lap ratio through visual inspection and experience of the operator, and in actual practice, it is difficult to obtain the desired lap ratio.

In view of the above problems, the present invention provides a new method for laying an industrial adhesive bandage, and provides a new industrial adhesive bandage and an industrial adhesive bandage package in combination with the laying method. Fig. 1-3 are schematic views of an industrial bandage according to one embodiment of the present invention, fig. 1 is a front view showing the external appearance of a package of the industrial bandage, and fig. 2-3 are rear views respectively showing a sealing cover attached to a sub-bag body and a sealing cover removed from the sub-bag body.

The main bag body 1 and the auxiliary bag body 4 can be made of conventional materials for forming bag body package, the main bag body 1 and the auxiliary bag body can be combined together in a thermoplastic mode and can be integrally formed, the main bag body 1 is in a vacuum state, so the periphery of the main bag body is strictly sealed, and the sealing edge 2 of the main bag body 1 is provided with an easy-to-tear opening 3 for conveniently tearing the main bag body 1; the auxiliary bag body 4 does not need to keep a high vacuum state, and the bag opening can be closed by a buckling sealing edge 41 which can be repeatedly opened and closed.

In order to close the auxiliary pocket 4 during storage and transportation of the product, it is necessary to close the opening 43 of the auxiliary pocket 4, and here, a sealing cover 42 is used, and the sealing cover 42 covers the opening 43 and is adhered to the periphery of the opening 43.

Considering the step of squeezing the water of the adhesive tape, a water squeezing belt is arranged in the auxiliary bag body 4 and is used for squeezing out the water on the adhesive tape 11 of the industrial band aid. Thus, in the industrial woundplast package, the adhesive tape 11 and the wringing tape are included, the adhesive tape 11 is disposed in the main bag body 1, and the wringing tape is disposed in the auxiliary bag body 4, see fig. 4.

A wringing strip according to an embodiment of the present invention is described below with reference to figure 6, the wringing strip comprising: pressing sheets 21; a pull tab 22, the pull tab 22 being attached to one edge of the pressing sheet 21; a pull tab 24 attached to an end of the pull tab 22 remote from the pressing sheet 21; and the connecting buckle 23, wherein the connecting buckle 23 is a rectangular metal sheet, a first through hole 231 and a second through hole 232 which are long in strip shape are arranged in the metal sheet, one side of the pressing sheet 21 far away from the pull tab 22 passes through the first through hole 231 and is fixed on one side of the connecting buckle 23, and a plurality of liquid seepage holes 25 which are uniformly distributed are arranged in the pull tab 22. The pressing sheet 21 and the pulling-on piece 22 may be made of woven cloth as long as they can bear a certain pulling force, and when in use, the adhesive tape 11 is placed on the pressing sheet 21, the pulling-on piece 22 is passed through the second through hole 232 by bypassing the adhesive tape 11, then the handle 24 is pulled by holding the connecting buckle 23, and a uniform pressure is applied to the adhesive tape 11, thereby squeezing out excess moisture.

Preferably, a holding portion is disposed on an edge of the connecting buckle 23 away from the first through hole 231 for holding the connecting buckle 23 by hand.

According to a preferred embodiment of the present invention, the auxiliary bag body 4 includes rubber gloves therein, which are used when the constructor opens the main bag body 1 to take out the adhesive tape 11, so as to prevent the sticky substance from being stained on the hands, and also to keep the adhesive tape 11 from being contaminated.

The invention provides a brand-new industrial bandage package which is characterized by comprising a main bag body and an auxiliary bag body, wherein the main bag body is mainly used for containing an adhesive tape of an industrial bandage when the industrial bandage package is not opened, the auxiliary bag body is used for containing the adhesive tape of the industrial bandage when the adhesive tape of the industrial bandage is taken out of the package and then is pasted, namely, the auxiliary bag body temporarily contains the adhesive tape in the process of pasting the adhesive tape. The tape is very easily contaminated in the tape-sticking process, for example, the non-sticking part of the tape is contaminated by particles and dust, which can affect the adhesion of the tape and the repairing effect. Through setting up the auxiliary bag body, allow constructor to put the sticky tape in the auxiliary bag body at the work progress, pull out the sticky tape through the opening of the auxiliary bag body, avoid polluting. Therefore, the industrial band-aid of the invention can facilitate the execution of construction operation specifications.

Further, since the adhesive tape based on glass fiber and high performance polyurethane is a water-curable adhesive tape, the adhesive tape is usually placed in water to contact water and then squeeze out excess water when in use, and the volatilization of water also constitutes a part of the curing factor, and the curing time of the adhesive tape of the industrial band aid can be controlled by placing the wetted adhesive tape in the auxiliary bag body.

In addition, the industrial band-aid provided by the invention also comprises a water squeezing belt, which is a tool for assisting in executing construction operation specifications, when the industrial band-aid is applied, the tape needs to be placed in water to contact water, because the tape based on glass fibers and high-performance polyurethane is a water-cured tape, and after the tape contacts water, excessive water needs to be squeezed out.

FIG. 7 shows an industrial bandage according to one embodiment of the present invention, with indicating lines provided on the back of the tape 11 of the industrial bandage. Before specific description, referring to fig. 10, description will be made on the lap ratio and the inclination angle of the tape, where fig. 10 schematically shows the relationship between the lap ratio and the circumferential length of the duct and the width of the tape, where T is the width of the tape 11, θ is the angle of the acute angle formed by the line parallel to the axis of the duct and attached to the duct at the start of winding and the width direction of the tape, representing the inclination degree of the tape, y is the length of the line parallel to the axis of the duct and attached to the duct at the start of winding, x is the length not attached by the upper layer of tape over the length y, and z is the circumferential length of the duct, and then the lap ratio s is:

s＝(y-x)/y＝1-x/y

wherein, length y and length x are respectively:

y＝T/cosθ

x＝z*tanθ

thus, s is 1-z sin θ/T

Thus, the angle θ can be derived with the circumference z of the pipe to be repaired, the width T of the tape, and the desired overlap ratio s determined.

θ＝arcsin(T*(1-3)/Z)

On the other hand, at the repair site, the three of the circumferential length z of the pipe to be repaired, the width T of the tape and the expected lap ratio s can be determined, so that the inclination angle θ, which is the angle of the straight line parallel to the axis of the pipe and applied to the pipe at the start of winding with respect to the width direction of the tape, can be calculated, and this angle can be determined by the angle indicating line to be described later to guide the winding of the tape. The width direction of the adhesive tape may be defined as a first direction, which is a direction perpendicular to the longitudinal extension direction of the adhesive tape on the surface of the base.

As described above, the adhesive tape 11 includes the base 111 and the cured layer 112 disposed on the base 111, in fig. 7, an angle indication line 113 and a lap indication line 114 are disposed on a side of the base 111 facing away from the cured layer 112, the angle indication line 113 is used for indicating an angle between the angle indication line 113 and a first direction, the first direction is a direction perpendicular to a longitudinal extending direction of the adhesive tape 11 on a surface of the base 111, and the lap indication line 114 is used for indicating a proportion of a lap width between an upper layer to be pasted and a lower layer to be pasted to a width of the adhesive tape 11 when the adhesive tape 11 is spirally wound, wherein the lap width is a dimension of a portion of overlap between the upper layer to be pasted and the lower layer to be pasted in a width direction of the adhesive tape 11. Therefore, the overlap width can be understood as the overlap width.

Wherein the angle indicating line 113 includes a plurality of straight lines which intersect at a point on the longitudinal side of the tape 11 and extend toward the transverse side of the tape 11 and the other longitudinal side parallel to the longitudinal side.

Here, the angle indicating lines 113 correspond to a straight line having a length y in fig. 10, an included angle between adjacent angle indicating lines 113 is 10 degrees, and when an angle θ required for ensuring the determination of the lap ratio is calculated to be 30 degrees according to the above formula, a 3 rd angle indicating line from a transverse line of the tape is selected in fig. 7 so that the angle indicating line is parallel to the axis of the pipe when the tape is wound, and then the lap ratio after the tape is wound is the desired lap ratio. The angles at both ends in fig. 7 indicate that the straight lines of the line groups are directed differently because they correspond to different winding directions, respectively, and when winding from right to left is required, winding is started using the right end of the adhesive tape; when winding from left to right is desired, winding is started using the left end of the tape.

In the embodiment of fig. 7, the back surface of the base of the tape is further provided with a lap indication line 114, and the lap indication line 114 includes a plurality of straight lines parallel to the longitudinal edges of the tape 11. Specifically, the lap indication lines 114 include 1/4 indication lines, 1/3 indication lines, 1/2 indication lines, 2/3 indication lines and 3/4 indication lines, and 1/4 indication lines, 1/3 indication lines, 1/2 indication lines, 2/3 indication lines and 3/4 indication lines respectively indicate that the ratio of the lap width between the upper layer to be pasted and the pasted lower layer to the width of the tape 11 when the tape 11 is spirally wound is 1/4, 1/3, 1/2, 2/3 and 3/4. Wherein the same line may be both an 1/3 indicator line and a 2/3 indicator line because there are two winding directions of the tape and the 1/3 indicator line when the right side is wound corresponds to the 2/3 indicator line when the left side is wound.

Having described the industrial adhesive bandage and the packaging for the industrial adhesive bandage used in the application method of the present invention, the application method of the industrial adhesive bandage according to the embodiment of the present invention will be described below with particular emphasis.

According to the present general inventive concept, there is provided an industrial adhesive bandage application method for adhering an industrial adhesive bandage to an object to be repaired, the application method performing the adhesion of the industrial adhesive bandage using an industrial adhesive bandage package and/or elements within the industrial adhesive bandage package as a tool.

Fig. 11 shows a flow chart of a laying method of an industrial adhesive bandage according to an embodiment of the invention, fig. 12 schematically shows part of the operation process of the laying method of the industrial adhesive bandage according to an embodiment of the invention, wherein fig. 12 comprises four sub-figures from top to bottom, as shown in fig. 11-12, the laying method comprises:

step A: the basic treatment comprises the steps of removing attachments of the part to be repaired, polishing the part to be repaired, roughening the surface of the part to be repaired, cleaning the part to be repaired and/or drying the part to be repaired, and the final purpose is to keep the part to be repaired clean and adhesive.

And B: extruding the dressing for the industrial band-aid onto the part to be repaired, and polishing the surface of the part to be repaired; the dressing for the industrial band-aid is a material suitable for filling pits and grooves on a part to be repaired, has fine granularity and adhesiveness, can be constructed by talcum powder or calcium carbonate, high-molecular resin and a binder, and preferably can be constructed into a rod shape with a concentric core. Based on the use of the dressing rod for the industrial band-aid, the step B further comprises the following steps: cutting a dressing with a preset dosage from a dressing rod for the industrial band-aid, and uniformly kneading by hand; adhering the dressing to the part to be repaired within 3-5 minutes, and removing redundant hardening substances; and rubbing the surface of the dressing by dipping water in hands to make the surface of the dressing smooth. The dressing bar for industrial band-aid contains a polymer resin component, which may be irritating to skin-sensitive people, so that soap and who should wash hands and touch the parts after use.

And C: calculating an inclination angle theta according to the width of the adhesive tape 11, the winding perimeter of the object to be repaired and an expected lap joint proportion, wherein the inclination angle theta is an acute angle formed by a straight line which is attached to the object to be repaired at the beginning of winding of the adhesive tape and is parallel to the axis of the object to be repaired and the width direction of the adhesive tape; the specific determination method has been described above, that is, in step C, the inclination angle θ is calculated using the following formula:

θ＝arcsin(T*(1-s)/z)

wherein T is the width of the tape 11; z is the winding perimeter of the object to be repaired; s is a desired lap ratio, which is a ratio of a lap width between the upper layer to be pasted and the pasted lower layer to a width of the adhesive tape when the adhesive tape is spirally wound, wherein the lap width is a dimension of a portion overlapping between the upper layer to be pasted and the pasted lower layer in a width direction of the adhesive tape.

Step D: opening the auxiliary bag body 4 packaged by the industrial band-aid, taking out the rubber gloves, and putting the rubber gloves on the auxiliary bag body; then tearing off a main bag body 1 packaged by the industrial band-aid, wherein the main bag body 1 is provided with an easy-to-tear opening 3, tearing off the main bag body 1 through the easy-to-tear opening 3, and pouring a proper amount of water into the main bag body 1, as shown in the sub-figures 1-2 of figure 12; the main bag body 1 may be provided with a water level line indicating the amount of water poured, and then the adhesive tape 11 in the main bag body 1 is taken out and the water squeezing tape is taken out from the auxiliary bag body 11. Alternatively, the main bag body 1 may be provided with a tear-off opening at a lower angular position thereof, so that the adhesive tape 11 is not removed from the main bag body 1, but instead the tear-off opening is torn to allow water to flow out naturally, and the main bag body 1 is grasped appropriately to squeeze the adhesive tape 11 to remove a part of the water, thereby preventing the adhesive tape 11 from coming into contact with air too early.

Step E: placing the adhesive tape 11 on the pressing sheet 21 of the wringing tape, passing the pull tab 22 through the second through hole 232 around the adhesive tape 11, and then pulling the handle 24 by holding the connecting button 23 with hand to squeeze out excess moisture in the adhesive tape 11, see fig. 12, sub-fig. 3; in this step, the tape 11 and the pouch are also placed together on a wringing belt for wringing, again with the aim of avoiding premature contact of the tape 11 with air.

Step F: the sealing cover 42 of the auxiliary bag body 4 is removed, the auxiliary bag body 4 is opened again, the adhesive tape 11 is put into the auxiliary bag body 4, and the end of the adhesive tape 11 is exposed through the opening 43 of the auxiliary bag body 4.

Step G: the deviation angle of the adhesive tape 11 with respect to the object to be repaired is determined using the angle indication line 113 on the adhesive tape 11 according to the inclination angle theta such that the acute angle formed by the straight line parallel to the axis of the object to be repaired, which is stuck to the object to be repaired at the start of winding, and the width direction of the adhesive tape is equal to the inclination angle theta, and then the adhesive tape 11 is wound, see fig. 4, and the adhesive tape 11 is stuck to the object to be repaired without wrinkles by pressing the adhesive tape 11 with a hand.

Step H: the lap indication line 114 is used to monitor whether the lap ratio of the tape 11 is as expected during the winding of the tape 11. The criterion for the desired overlap is that the difference between the actual overlap ratio and the desired overlap ratio should be less than 1/4 of the tape width, and if not, the application method provides that the application should be repeated.

Then, the steps G and H are repeated a plurality of times, and the direction in which the adhesive tape 11 travels along the object to be repaired when the adhesive tape 11 is wound is different for the adjacent two steps G, that is, the adjacent two steps G, one time are wound from the first end to the second end of the object to be repaired, and the other time are wound from the second end to the first end of the object to be repaired. Further preferably, in two steps G spaced by one step G (the winding traveling directions of the two steps G are the same), the winding directions of the wound tape 11 are opposite, that is, one is clockwise winding and one is counterclockwise winding. The winding process should be applied with a little force, and 4-10 layers are wound according to the leakage and breakage conditions. After winding is finished, the adhesive tape is cured and molded after about 20 minutes, and the pipeline can be normally used after about 1 hour.

Advantageously, in said step G, after the tape 11 is wound, the tape 11 is manually pushed several times in the winding direction. When the object to be repaired is a pipeline, the laying method further comprises the step of closing the valve and eliminating the pressure in the pipeline before the step A.

The industrial band-aid of the invention is insulated per se, but in order to increase the insulation and improve the puncture resistance, the laying method also comprises winding a reinforcing insulating layer outside the adhered adhesive tape.

Further, the laying method further comprises: and after the step B and before the step D, adhering a layer of adhesive film on the surface of the part to be repaired, wherein the roughness of the adhesive film is greater than that of the material of the object to be repaired, the adhesive film is adhered by adopting a spiral winding method, and the lap joint proportion of the adhesive film is different from that of the adhesive tape of the industrial band-aid.

Although embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention. The scope of applicability of the present invention is defined by the appended claims and their equivalents.
