There is the difficulty relevant to these containers.For example, some materials are sold in cartridge case and are used for packing into Joint sealing material distributing box or rifle.Distributing box or rifle are other necessary purchase, storage, cleaning and the article of safeguarding as the part of joint filling technique.Distributing box or rifle may be heavy and be difficult to operation, and be especially true in the restricted clearance of just under construction building.In addition, distributing equipment may require significant hand-power, and this has increased the challenge that distributes and lay clean aquaseal bead.
In one approach, a certain amount of aquaseal directly is pressed onto the crack to seal this zone when dry from distribution pipe or cartridge case.Generally speaking, the material that comprises of distribution pipe or cartridge case will be more than the specific required amount of seal operation.Usually keep some untapped tube portions after distributing required amount.The distribution pipe that will have unused portion abandons or preserves for using future.Abandon and be uneconomic and may do not wish very much for environmental factor.The known recovery method that not can be used at present commercially available various encapsulant compositions.
If do not abandon the container with remaining aquaseal, it must be covered to preserve material and be used for following the use in noncondensing situation.But aquaseal may comprise the volatile constituent that residual materials is solidified evaporation.Other aquaseals may solidify from being exposed under aerial oxygen.Unless and container suitably sealed again, otherwise residual materials will be lost.
Some dispense container sell to provide the secure fit of container body together with slipping into of nozzle engagement coordinates pearl (snap-fit bead) and groove or screw thread.But these lids are frangible sheets, and it easily splits due to over-tension or otherwise damages.Perhaps, slipping into cooperation pearl and groove may be until coordinates when needing to manage the sealing again that just can provide lasting when working for joint filling subsequently.Some informal closure cap applying apparatus comprise that nail is put into tube opening to be sealed again to carry out plug type.Perhaps, container cover may sell to provide this function together with stopper element.But usually, these solutions can not prevent that over certain short time content from solidifying.
Other again enclosure method comprise with aluminium foil or plastic packets wrapping container tip, with rubber tape fix and with whole container encloses in sealable plastic wrapping body.But these mechanisms can not work usually, because packaging body breaks or packaging body comprises enough air and makes the pipe content dry.And paper tinsel or parcel can not be closely and are wrapped in densely pipe and nozzle does not have on every side a. g..
