Chemical barrel is the tool for holding chemical industry materials, dyestuff, medicine, pesticide.Chemical barrel is made of plastic mostly
It forms, be generally called plastics chemical barrel and plastic cement chemical barrel, is blow molded with scientific formula development, color multiplicity, shape
Beautiful and generous, corrosion-resistant in acid and alkali-resistance, anti-leak is not faded, it is indeformable etc. reach packaging property index, it is good and cheap, be
The ideal chose that chemical products packaging material far transports on the way at present.
However, since the main composition material of chemical barrel is polyethylene (polyethylene, PE), therefore chemical barrel uses
After complete, inner wall generally can all remain a large amount of greasy dirts or chemical industry materials, to recycle chemical barrel, then need to carry out chemical barrel clear
It washes.Cleaning chemical barrel needs the enterprise to professional cask washing to go, and cleaning up is not only troublesome, and cleans at high cost.Chemical barrel
It is also easy to cause environmental pollution after industrial wastewater discharge after cleaning.Remaining industrial chemicals can only be cleaned in chemical barrel
Fall and cannot be recycled well.So remaining chemical industry is former in chemical barrel from saving for angle and environmental angle
Expect that processing technique is currently a very big notch.
It can be seen that above-mentioned existing chemical barrel is in structure and use, it is clear that there are still there is inconvenient and defect, and urgently
It is further improved.To solve the above problems, relevant manufactures there's no one who doesn't or isn't painstakingly seek solution, but long
Have no that applicable design is developed completion since long always, and common product is able to solve the above problem without appropriate structure,
This is clearly the problem of correlation dealer is suddenly to be solved.
In view of this, being applied to chemical barrel, the inner lining bag includes bag body, described the present invention provides a kind of inner lining bag
One end of bag body is equipped with pan feeding portion, and feeding inlet is arranged in the one end in the pan feeding portion, and the pan feeding portion includes side wall, the side wall with
The bag body connection, the edge of the one end of the side wall far from bag body are equipped with sealing film, and the sealing film is layed in described
The other end of the bung hole outer of chemical barrel, the bag body is equipped with discharge part.Inner lining bag of the invention, which passes through, to be arranged in chemical barrel,
For holding chemical industry materials, chemical industry materials are isolated with chemical barrel, the cleaning procedure after chemical barrel use is avoided, also avoids
The industrial wastewater discharge of cleaning chemical barrel and cause environmental pollution.Also, remaining chemical industry materials can remain on inner lining bag
In, remaining chemical industry materials are can be recycled into broken hole below inner lining bag.Inner lining bag can be membrane structure, buy inner lining bag at
This has saved cost well below the cost for cleaning chemical barrel, therefore for enterprise.
Referring to Fig. 1, showing the structural schematic diagram of the inner lining bag 10 of present pre-ferred embodiments offer.The present invention is preferable
