Profession coagulation operator

Coagulation operators control machines to coagulate synthetic rubber latex into rubber crumb slurry. They prepare these rubber crumbs for finishing processes. Coagulation operators examine the appearance of the crumbs and adjust the operation of filters, shaker screens and hammer mills to remove moisture from the rubber crumbs.

  • Weigh materials

    Weigh materials and products, record weight and other relevant data on tags or labels.

  • Monitor tank thermometer

    Monitor the tank in order to prevend explosion or decomposition due to an accumulation of heat.

  • Avoid contamination

    Avoid the mixing or contamination of materials.

  • Monitor valves

    Monitor and accordingly adjust the valves in order to allow a specific amount of liquids (such as ammonia sulfuric acid or viscous soap) or steam into the mixer or machine.

  • Extract fatty acid

    Extract fatty acid obtained through the conversion of creamy latex into coagulated slurry which is further processed in the soap conversion tanks.

  • Fill the mixing tank

    Fill the mixing tank with the chemical ingredients, allowing also the water through the valves at the indicated mark on the tank wall.

  • Segregate raw materials

    Segregate into batches the raw materials to be further processed.

  • Process latex mixtures

    Process latex mixtures using control panels in order to obtain rubber products such as foam rubber sheets, balloons or finger cots.

  • Operate precision measuring equipment

    Measure the size of a processed part when checking and marking it to check if it is up to standard by use of two and three dimensional precision measuring equipment such as a caliper, a micrometer, and a measuring gauge.

  • Use personal protection equipment

    Make use of protection equipment according to training, instruction and manuals. Inspect the equipment and use it consistently.

  • Optimise production processes parameters

    Optimise and maintain the parameters of the production process such as flow, temperature or pressure.

  • Measure materials

    Measure the raw materials prior to their loading in the mixer or in machines, ensuring they conform with the specifications.
