Abstract
The invention discloses a method for preventing liquid metal gallium from being adhered to the inner wall of a container. The method is characterized in that the inner wall of the container is passivated. The container is made of a plastic material, such as PVC (Poly Vinyl Chloride), PE (Poly Ethylene), PP (Propene Polymer), ABS (Acrylonitrile Butadiene Styrene) and nylon. According to the method provided by the invention, the liquid metal gallium is prevented from being adhered on the inner wall of the plastic container by using a method applicable to the passivation of the plastic surface according to a surface physical principle and the properties of the inner wall of the plastic container. With the adoption of the method provided by the invention, not only can the loss, caused by the factor that the gallium is dissolved in a hydrochloric acid solution or sodium hydroxide solution, be avoided, but also the gallium can be prevented from being polluted by acid or alkali.
Description
Technical field
The present invention relates to a kind of method that liquid adheres to container inner wall of eliminating, relate in particular to a kind of method that the liquid metal gallium adheres to container inner wall of eliminating.
Background technology
The liquid metal gallium infiltrates all metal surfaces, even glass, pottery and frosting.For avoiding metallic pollution, the container of containing gallium all is made of plastics.But no matter plastic containers are PVC, PE, PP, ABS or nylon, contained liquid gallium after, inwall overworks the gallium film, can't take off.A 1000mlPE beaker is hung gallium 6g, and the PP bucket of a 3L is hung gallium 20g, and the PP bucket of a 5L is hung gallium 30g.
In the prior art, with hydrochloric acid solution or sodium hydroxide solution, can change the contact angle of liquid gallium and plastic cover, make the gallium film be shrunk to bead and come off, but on the one hand the gallium part is polluted by acid or alkali on the other hand by hydrochloric acid or sodium hydroxide solution dissolving and incur loss; The non-stick pan of spraying plating TEFLON is not infiltrated by liquid gallium, but liquid gallium can not be used canister, and plastic containers can not be accepted the high temperature spraying plating of TEFLON.
Summary of the invention
The object of the invention is to overcome the above-mentioned weak point of prior art, according to the surface physics principle, with the method for passivation container inner wall, the contact angle of the frosting after change liquid metal gallium surface and the passivation reaches the purpose that the liquid metal gallium no longer adheres to container inner wall.
The technical scheme that realizes the object of the invention is: a kind of method of eliminating liquid metal gallium adhesion container inner wall, it is characterized in that, and container inner wall is carried out Passivation Treatment.The material of container is plastics, such as PVC, PE, PP, ABS, nylon etc.,
Passivation process is as follows: with granularity be 10 ~ 100 order sands to the container inner wall sandblast, make the container inner wall passivation; Perhaps with granularity be 100 ~ 500 order Buddha's warrior attendant mortars to the container inner wall rubbing down, make the container inner wall passivation: perhaps use 100 order fabric discs to the container inner wall rubbing down, make the container inner wall passivation.
The beneficial effect that the present invention compared with prior art has is: the inventor has analyzed the principle of surface physics, characteristic according to the plastic containers inwall, adopted the method for suitable frosting passivation, realize eliminating the liquid metal gallium to the adhesion of plastic containers inwall, this method both can have been avoided gallium by the dissolving of hydrochloric acid or sodium hydroxide solution and incur loss, and can avoid again gallium to be polluted by acid or alkali.
The specific embodiment
The present invention is further described in more detail below in conjunction with specific embodiment.
Embodiment 1: get plastics (PE) beaker of 2 1000ml, one of them uses granularity is that 10 purpose Buddha's warrior attendant mortars carry out the inwall rubbing down, makes its inwall passivation.Another one does not deal with.Clean up these two beakers after anhydrous, add respectively 6kg liquid metal gallium, leave standstill 2 minutes after, gallium is wherein poured out.Observe, the plastic beaker inwall that does not deal with has sticked the gallium layer, and a gallium does not adhere to yet on the plastic beaker inwall of passivation.
Embodiment 2: its difference from Example 1 is, gets plastics (PE) beaker of 2 1000ml, and one of them uses granularity is that 75 purpose Buddha's warrior attendant mortars carry out the inwall rubbing down, makes its inwall passivation.Another one does not deal with.Clean up these two beakers after anhydrous, add respectively 6kg liquid metal gallium, leave standstill 2 minutes after, gallium is wherein poured out.Observe, the plastic beaker inwall that does not deal with has sticked the gallium layer, and a gallium does not adhere to yet on the plastic beaker inwall of passivation.
Embodiment 3: its difference from Example 1 is, gets plastics (PE) beaker of 2 1000ml, and one of them uses granularity is that 100 purpose Buddha's warrior attendant mortars carry out the inwall rubbing down, makes its inwall passivation.Another one does not deal with.Clean up these two beakers after anhydrous, add respectively 6kg liquid metal gallium, leave standstill 2 minutes after, gallium is wherein poured out.Observe, the plastic beaker inwall that does not deal with has sticked the gallium layer, and a gallium does not adhere to yet on the plastic beaker inwall of passivation.
Embodiment 4: its difference from Example 1 is, gets plastics (PVC) beaker of 2 1000ml, and it is that 200 purpose Buddha's warrior attendant mortars carry out the inwall rubbing down that one of them beaker uses granularity, makes its inwall passivation.Clean up these two beakers after anhydrous, add respectively 6kg liquid metal gallium, leave standstill 2 minutes after, gallium is wherein poured out.Observe, the plastic beaker inwall that does not deal with has sticked the gallium layer, and a gallium does not adhere to yet on the plastic beaker inwall of passivation.
Embodiment 5: its difference from Example 1 is, gets plastics (PP) Plastic Drum of 2 2000ml, and one of them uses granularity is that 500 purpose Buddha's warrior attendant mortars carry out the inwall rubbing down, makes its inwall passivation.Another one does not deal with.Clean up these two Plastic Drums after anhydrous, add respectively 10kg liquid metal gallium, leave standstill 2 minutes after, gallium is wherein poured out.Observe, the inner wall of plastic that does not deal with has sticked the gallium layer, and a gallium does not adhere to yet on the inner wall of plastic of blunt mistake.
