Since the release and compression of the negative pressure drainage bag 1 ideally proceed straight along the vertical direction, but actually, because of the transient nature of the spring recovery and the deviation of the stress points of the first grip 223 and the second grip 224 on the pressing plate 222, these two processes may generate more or less non-vertical forces, which requires the T-shaped clamping block 221 to perform the function of fixed guiding, which increases the friction between the T-shaped clamping block 221 and the fixing groove 213 to some extent, which increases the wear of the T-shaped clamping block 221, so that a wear-resistant layer is coated on the T-shaped clamping block 221 to protect the T-shaped clamping block 221, which slows down the wear of the T-shaped clamping block 221 and prolongs the service life thereof, wherein the wear-resistant strength and peel strength data of embodiment 4 are optimal, so that the optimal formula is finally determined: 49 parts of epoxy resin, 17.5 parts of acrylic resin, 13 parts of nano amorphous silicon nitride powder, 8.5 parts of nano iron oxide, 5 parts of polyurethane resin, 2.5 parts of graphite powder, 1.5 parts of ceramic micropowder, 4.5 parts of calcium carbonate kaolin, 1.5 parts of wood powder, 26 parts of styrene, 4 parts of triethanolamine, 3.5 parts of propylene glycol monobutyl ether, 2.2 parts of polydimethylsiloxane, 1.4 parts of fatty glyceride and 1.5 parts of octylphenol polyoxyethylene ether.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it is understood that "first" and "second" are only used for convenience of expression and should not be understood as limitations to the embodiments of the present invention, and the following embodiments do not describe any more.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
