Substrate protective structures, including high performance polymers and polymer coatings from 1 to over 2500 mils thick, are disclosed. The structures protect metal and other surfaces with heat resistant, abrasion resistant, and chemical inert polymers. The structures are applied to the substrate in a manner that provides easy processing of curved and bent surfaces, increased adhesion of metal to polymer, greater resistance to mechanical and thermal stresses that cause cracking and de-lamination, and increased environmental resistance.

The invention discloses a well testing steel wire releasing tool which comprises a salvage head, a mandrel, an outer spring, a transposition pin, an upper torque ring, a rotary nut, an outer cylinder,a lower torque ring, an inner spring and a duckbill. The well testing steel wire releasing tool is connected into a well testing tool string and lowered into a well with all tools simultaneously, when the tool is clamped and cannot be unclamped through other unclamping tools, a well testing steel wire can be gently lifted and lowered up and down, when the number of lifting and lowering times reaches a certain numerical value, downhole tool releasing is achieved, all the tools above the well testing steel wire releasing tool can be safely lifted to the ground, the construction loss is reducedto the largest limit, and well testing steel wire fatigue caused by multiple-time shock can also be avoided.

The invention discloses a TPR shoe surface modification technology. The modification technology comprises the following steps of (1) a TPR shoe surface processing step, in which a TPR specific processing agent is employed to clean the external surface of the shoe and soften the external surface, and the shoe external surface is dried for 10 to 20 minutes, (2) a priming paint spraying step, in which a paint spraying device is employed to spray priming paint to the TPR shoe to form a flat priming paint plane on the external of the TPR shoe, and then the shoe sprayed with the priming paint is dried by 10 to 20 minutes at the temperature of 60 to 70 DEG C, (3) a metal spraying step, in which a spraying device is employed to spray an imitating metal layer on the priming paint, and then the imitating metal layer is dried for 5 to 10 minutes at the temperature of 60 to 70 DEG C, and (4) a spraying device is employed to spray a layer of surface paint on the external surface of the imitating metal layer and then the shoe is dried. The modified shot can be achieved at last. The priming paint is composed of the following components according to weight by parts: 100 parts of base main resin, 10 to 30 parts of hardener, 30 to 80 parts of diluents and 1 to 10 parts of binding agents; and the surface paint is formed by the following components according to weight by parts: 100 parts of surface main resin, 30 to 50 parts of hardener, 50 to 80 parts of diluents and proper pigment. The TPR shoe surface modification technology is characterized by great decorating effect.
