A rubber hose wrapping vulcanization process is characterized in that a polyester film is used instead of a traditional water-wrapping cloth as the outer layer pressurized material when the rubber hose is vulcanized. The polyester film is made of polyethylene terephthalate as a raw material, melted and extruded after drying to make a thick sheet, and then a film with a smooth surface and uniform thickness made by longitudinal and horizontal biaxial stretching and heat treatment. The film thickness is 30-50 μm and has physical and mechanical properties meeting certain requirements. The characteristics of this new process are that the process is simple, it can be applied to all specifications of rubber hoses, the equipment investment is small, the cost is low, and the finished rubber hoses have good overall compactness and smooth appearance.

The invention discloses a method for improving the flexibility of a yak decorative fur / leather cutis plate by acid swelling and splitting. In the method, acid swelling, combing, tidying and splitting are sequentially carried out after a degreasing procedure in the conventional production of a yak decorative fur / leather, wherein acid swelling liquid used in the acid swelling procedure is prepared from the following materials: 2-5g / L of acidic materials, 5-15g / L of acid swelling regulator and water as the solvent; and the control process parameters are as follows: the temperature is 20-30 DEG C, the rotation speed of a rotor drum is 3-6r / min, the liquor ratio is 8-10, and the time is 24-48 hours. The invention breaks with convention to skillfully make use of the acid swelling regulator to carry out splitting under the condition that collagen fibers of the cutis plate are moderately swollen, loosened and increased in thickness by the acidic materials, so that the thickness of the cutis plate is greatly decreased, the uniformity of the cutis plate is improved, and the penetration of chemical materials in subsequent procedures as well as the dispersion or lubrication effect of the chemical materials on the collagen fibers of the cutis plate is promoted, and therefore, the flexibility of the yak decorative fur / leather cutis plate is greatly improved.

The present invention belongs to a technique for judging pile body quality in the course of driving pile of ocean engineering. Said technique includes the following steps: according to pile-driving record of construction field and theoretical formula utilizing one-dimensional wave equation to simulate continuous pile-driving process, calculating to obtain relation curve of pile penetration and number of blow in pile driving, regulating calculation parameters of Qs, Qp, Sf, Jp and Js to make the calculated curve can be better fit with pile-driving record curve so as to define values of Qs, Qp, Sf, Jp and Js; using this as basis to make sequent pile-driving analysis, utilizing regulation of f and q values to simulate driving refusal phenomenon; using finally-defined f and q values to calculate actual bearing capacity of single pile, and comparing it with design-calculated bearing capacity of single pile so as to define the treatment of pile body when the sequent pile-driving is refused.

The invention discloses a preparation method of a sealing type gamma ray source in a radioactive density meter, which belongs to the technical field of radioactive well logging. The method comprises the following steps: transferring isotopic elements into a source storage container in a state of a water solution of compounds thereof; controlling the total activity of the water solution of the isotopic element compounds in the source storage container between 30 and 70 mCi; adding water-soluble precipitating agents for precipitating compounds containing the isotopic elements; and sealing the source storage container in a sealed way after heating and drying to obtain the sealed type gamma ray source, wherein the half life of the isotopic elements is shorter than 60 days, in addition, a gamma ray with the energy between 0.1 and 1.4 Mev can be released through the disintegration, and at the same time, the disintegration mode accounts for 40 percent of the total disintegration of the isotopic elements. The gamma ray energy of the sealing type gamma ray source prepared by the invention is in the radioactive density meter sensing range in common use in the well logging, the half life is short, the environment pollution is little, the sealing type gamma ray source can directly replace the original 137 Cs density source on the radioactive density meter, and at the same time, the invention has the advantages of simplicity and easy implementation of production process, easy acquisition of raw materials and low cost, and has wide market potential.
