How to Solve Vulcanizing Machine Oil Leak Problems:

Vulcanizers sometimes leak oil. If the treatment is not timely or improperly handled, it may cause serious accidents. Therefore, it should be prevented in advance to find a solution.

To solve the oil leakage of the vulcanizer, the process equipment (drilling formwork) can be used to drill through the oil hole to completely solve the shortcoming of the error of the oil passage between the two parts.

The specific operations are as follows:

  • The various holes (size holes) of the drill template are to be completely processed on the coordinate boring machine. The hole pitch error can be controlled within ±0.006mm imitation: the general hole spacing error is required to be 0.1mm. Positioned by the four screw holes of the valve, four positioning pins are mounted on the drill template and inserted into the four mounting holes of the valve body.
  • The four mounting screw holes of the valve body should be drilled to drill the bottom hole of the thread first, and the drill template is positioned to the four holes, and then the oil hole is drilled. The procedure of this processing can ensure that the center distance "X" of the oil passage of the valve body is aligned accurately, and oil leakage does not occur even when the oil temperature rises to 60 °C.

Factors That Effect Vulcanizing Effects:

The vulcanization process is affected by several factors in the vulcanization process, mainly due to the following three factors.

Sulfur consumption

The higher the amount of sulfur in the vulcanizer machinery, the faster the vulcanization rate will be, and the higher the vulcanization procedure will be. However, the solubility in sulfur and rubber is limited. It is not the greater the amount of sulfur used, the excess sulfur. It will be precipitated from the surface of the rubber compound. This phenomenon is called “sulphur spraying”. To minimize the occurrence of sulfur injection, the method is to add an appropriate amount of sulfur at the lowest possible temperature. Under normal circumstances, sulfur is used in soft rubber. Do not exceed 3%, semi-hard rubber does not exceed 20%, the amount of pure hard rubber is higher, up to 40%.

Vulcanization temperature

The vulcanization temperature determines the degree of vulcanization uniformity. When the temperature is 10 °C higher, the vulcanization time will be shortened by about half. The rubber is a poor thermal conductor, and the vulcanization process will be different depending on the temperature of each place. To achieve uniform vulcanization effect, thick rubber products The temperature control is very critical, and should be gradually warmed up. The principle is low temperature vulcanization for a long time.

Vulcanization time

Vulcanization time is an important link in the vulcanization process. If it is too short or the vulcanization process is not enough, it is commonly called “under sulfur: when it is too long, the vulcanization degree will be too high, commonly known as “persulfurization”, only the appropriate length of time can be reached. Vulcanization effect, commonly known as positive vulcanization.
