Description

A kind of foaming instrument

Technical field

The utility model relates to a kind of foaming instrument that makes foam gap filler ejection and foaming.

Background technology

About the door in building and the house, window, body of wall, coating, mix earth, percolation-proof such as timber and frosting is installed, joint filling or mending-leakage, the insulation that air-conditioning is installed, application of anti-leakage layers, various piping erection, fill in the surplus hole of ventilation opening and electric wire outlet, combined socket and switch and the relevant installation that needs insulation etc., generally all adopting foam gap filler is raw material, such as: foam gap filler can adopt and comprise gas and the chemical raw material that self has air pressure, comprise butane gas and urethane raw etc. such as employing, ejection post-foaming＜expansion〉and form foam-like, spontaneous curing again, during use, by foaming instrument foam gap filler is discharged and reach installation, joint filling, mending-leakage, insulation, insulation or purpose such as bonding, foam gap filler is generally in the foaming instrument internal channel and self has air pressure or than the liquid status of hyperbar, when opening liquid valve by switching device, expand and solidify and be bonded in needed place in the foam gap filler that ejects foaming back, but drain pipe exists the defective of following several respects; 1. when adopting iron pipe or copper pipe or aluminum pipe, because iron material or copper product or aluminum are easy to oxidation or are corroded and in tube wall, outer residual thing of generation or corrosion, destroy the sealing performance of feed liquor valve and/or fluid mouth easily and cause the phenomenon of leakage, the color of joint filling thing is polluted in residual thing or corrosion easily, influenced the quality of construction, in addition, the surface of longer drain pipe is easy to occur large-area rust staining or oxidation spot, make the surface become coarse and dirty, it is high especially that foam gap filler is bonded on the coarse surface fastness, very difficult cleaning maybe can't be cleared up and be made surperficial thickening, drain pipe is difficult to put in the less slit and constructs, cause constructional difficulties, even can't construct, reduced application life; If adopt thin material, insufficient strength is easy to occur distortion or damages and cause the phenomenon of leakage; If adopt thicker material, cost is very high, has wasted resource, and the volume of drain pipe is increased, and is difficult to put in the less slit and constructs, and use heavy, painstaking.2. when drain pipe adopts plastic pipe, long plastic tube wall is easy to occur pore or stream seam man-hour and causes the phenomenon of leakage adding, and insufficient strength, being easy to occur breakage or crack makes foam gap filler ejection and is bonded on one's body or is difficult to clean on the clothing or on the article, be bonded at accidentally on the eyes and can cause serious consequence, even the danger of burning or exploding also can appear, in addition, residual foam gap filler generally all adopts cleaning agent to clean in the post use plastic pipe, cleaning agent is easy to corrode plastics, plastics is dissolved or attenuation or break and cause the phenomenon of leakage; If plastic pipe is made thicker or bigger size, be difficult in the less slit and construct.
