Paraffin wax has little impact on the ecological environment and is mass-produced at low cost, so it is suitable as an antifouling material used in the short term. In addition to paraffin wax, polyethylene wax, candelilla wax, ceresin wax, etc. may be additionally blended. In any case, the content of paraffin wax among all wax components is maintained at 50 wt% or more.
이때, 파라핀 왁스를 에멀젼 상태로 하여 여타의 왁스를 혼합하고 25~55℃ 정도로 가열한 상태에서 20~30분간 혼합하는 것이 좋다. 설정된 온도를 초과하면 왁스의 물성이 열화되며, 온도가 미달되면 혼합에 요하는 시간이 증가된다.At this time, it is good to mix paraffin wax with other waxes in an emulsion state and mix for 20 to 30 minutes in a state of heating at about 25 to 55 ° C. If the set temperature is exceeded, the physical properties of the wax deteriorate, and if the temperature is not reached, the time required for mixing increases.
