  • One of the preferred methods is a method in which a tube made of the above resin is put on the outer periphery of a tubular base material (other layer) and the tube is heat-shrinked.
  • a method of applying a paint containing the above resin on another layer may be used.
  • the housing of the present disclosure is for a livestock sensor, and is used for constructing a livestock sensor.
  • the present disclosure also relates to a livestock sensor having the above-mentioned housing for a livestock sensor of the present disclosure and a detection unit housed inside the housing. Since the livestock sensor of the present disclosure includes the housing of the present disclosure, it is slippery, easy for livestock to swallow, and easy for oral administration. Therefore, it is possible to acquire highly reliable data without giving stress to livestock. In addition, since there are fewer restrictions on the shape and size of the housing, the degree of freedom in design is improved.
  • the livestock sensor is a sensor that is placed inside a livestock and detects the state of the livestock (pH, temperature, momentum (acceleration), etc.).
  • the livestock sensor is preferably configured so that it can be orally administered to livestock. Further, the livestock sensor is preferably a wireless transmission type sensor capable of wirelessly transmitting the acquired data.
  • Examples of the detection unit include a pH sensor, a temperature sensor, a piezoelectric sensor, an acceleration sensor, a position sensor, and the like.
  • the livestock is preferably a ruminant, and examples thereof include cows (dairy cows and beef cattle), sheep and goats. Of these, cows are preferred.
  • the livestock sensor is preferably placed in the internal organs of livestock, more preferably in the stomach, further preferably in the rumen, and more preferably in the rumen. ) It is particularly preferable to indwell in the liquid.
  • the livestock sensor is preferably indwelled in the body of livestock for 1 month or longer, more preferably 6 months or longer, further preferably 1 year or longer, and 3 years or longer. Especially preferable.
  • the livestock sensor preferably has a specific gravity of 1.8 or more, more preferably 2.0 or more. When the specific gravity is within the above range, it becomes easy to indwell (submerge) in a body fluid such as gastric juice.
  • the size of the livestock sensor is not particularly limited as long as it can be orally administered to livestock, but when it is cylindrical, it may have a diameter of 10 to 35 mm and a length of 40 to 150 mm, for example. ..
  • the livestock sensor 10 includes a housing 11, and the housing 11 corresponds to the housing of the present disclosure.
  • a signal processing circuit 13 connected to the battery 12 is housed inside the housing 11.

  • the flow value of PCTFE is a value measured by an elevated flow tester.
  • Test Example 1 Using each resin, a sheet having a thickness of 0.2 mm and a thickness of 120 mm ⁇ was produced by compression molding using a heat press. The PTFE was molded at a temperature 50 to 70 ° C. higher than the melting point and a pressure of 5 MPa. Other resins were molded at a temperature 40 ° C. higher than the melting point and a pressure of 3 MPa. The dynamic friction coefficient, static friction coefficient and elastic modulus of the obtained sheet were measured by the following methods. The results are shown in Table 1.
  • Examples 1 to 5 and Comparative Examples 1 to 2 A SUS304 housing having a diameter of 30 mm and a length of 150 mm was covered with a heat-shrinkable resin tube shown in Table 2 having a diameter of 36 mm, a wall thickness of 0.5 mm, and a length of 170 mm. Then, the tube was shrunk by heating at the melting point of the heat-shrinkable tube at + 20 ° C. for 10 minutes, and the SUS housing was covered with the resin. The sensor was assembled in a resin-covered housing, and the following simulated swallowing test was conducted. The results are shown in Table 2.
  • ⁇ Mock swallowing test> The time required for the sample to pass through the neoprene rubber tube having a diameter of 40 mm ⁇ and a length of 1000 mm installed at an inclination of 45 degrees was measured and evaluated according to the following criteria. ⁇ : Less than 10 seconds ⁇ : Less than 20 seconds ⁇ : 20 seconds or more or no sample appears
