The invention relates to an inward-wound seal packaging bag for ring-shaped cylindrical object and packaging method thereof, which comprises a flexible bag body corresponding to the inner surface and the outer surface of the ring-shaped cylindrical object, wherein two ends of the cylindrical bag body are open, and colloid is arranged at an opening on one side of the bag body; and the outer layer of the flexible bag body is made of plastic film and the inner layer of that is made of gas phase rustproof film coated on the inner wall of the outer layer. The sealing packaging is achieved by the following steps: the bag body is covered on the surface of a steel coil in a manner of aligning the edge of the ring-shaped cylindrical object like the steel coil; the rest of the bag body penetrate out from a ring-shaped hole of the steel coil; and the turned-over edge of the bag body is jointed with the bag opening previously covered on the other side of the steel coil surface via the colloid. In the invention, the VCI (Volatile Corrosion Inhibitor) gas phase rustproof film is used to seal the packaging, and the inner wall and the outer wall of the steel coil are fully coated, so that the sealing is good, the rustproof period is long, the ideal rustproof effect can be obtained, the substantive breakthrough in the rust prevention during the transportation to metal products is achieved, and the economic and social benefits are excellent.

The invention discloses a non-phosphorus water-based metal cleaner which is prepared from raw materials, namely, isodecanol polyoxyethylene ether, 1,3-butanediol, dodecanedioic acid, petroleum barium sulfonate, water, modified siloxane defoaming agent, sylvite, fatty alcohol polyoxyethylene ether, p-tertiary butyl benzoic acid, triazine polycarboxylic acid compounds, fatty alcohol-polyoxyethylene ether, benzyl alcohol fatty alcohol polyoxyethylene ether, isoundecanol polyoxyethylene ether, butyl cellosolve, n-hexane, glycol, glycerol, fatty alcohol-polyoxyethylene ether, fatty alcohol-polyoxyethylene ether, alkyl polymers or blocked polyether, castor oil polyoxyethylene ether, succinic acid derivative, boric acid, petroleum sodium sulfonate, imidazoline, methyl triazole, polyoxyethylene ether, fatty alcohol alcoxyl compounds, triazole, ether carboxylic acid organic chelating agents and the like. The non-phosphorus water-based metal cleaner is excellent in cleaning capability, long in anti-rusting period, low in foam, long in service life and applicable to ferrous metal and non-ferrous metal processing industry.

The invention discloses anti-rust oil used for an instrument. The anti-rust oil comprises, by weight, 40-60 parts of base oil, 20-30 parts of zinc naphthenate, 25-35 parts of lanolin, and the balancing being vaseline. The anti-rust oil overcomes the problems in the prior art. By using the anti-rust oil provided by the invention, the instrument has a good anti-rust effect and a long anti-rust period. Loss of enterprises is reduced. The anti-rust oil has high practicality and is suitable for wide application in related industries.

The invention discloses a rust prevention treatment solution for transmission case inner walls, which is composed of the following components in percentage by weight: 8-10% of oxalic acid, 7-9% of triethanolamine, 5-7% of citric acid, 6-8% of sodium petroleum sulfonate, 5.5-6.5% of fatty alcohol polyethenoxy ether, 3-5% of ammonium molybdate, 2-4% of sodium benzoate, 1.5-2.5% of sodium hydroxide, 2-4% of industrial alcohol, 1.5-3.5% of ethylene glycol and the balance of water.

The invention discloses a preparation method of a humidity regulating and release controlling type gas phase inhibitor. The preparation method comprises the following steps that step 1, a pure gas phase inhibitor is added to deionized water, and heating for dissolution is conducted; step 2, the temperature keeps unchanged, and a cosolvent with the volume of 0.2-2 times of the volume of the deionized water is added, so that the pure gas phase inhibitor is completely dissolved; step 3, a porous hygroscopic material is heated to the same temperature; step 4, under stirring, the dissolved gas phase inhibitor solution is added to a porous carrier which is heated to the same temperature, and even stirring is conducted; and step 5, drying of low temperature and vacuum is conducted on the mixtureevenly stirred, and all the cosolvent is removed to obtain the humidity regulating and release controlling type gas phase inhibitor. According to the preparation method, the gas phase inhibitor prepared has the function of adjusting the environmental humidity, and the volatilization speed of VCI can be controlled.
