calcium carbonate
During the transportation of calcium carbonate, its physical and chemical properties should be comprehensively considered to ensure its safe and efficient delivery to the destination. The following are the key points during transportation:
Preparations before transportation
Packaging inspection: Ensure that the packaging is intact and undamaged, and has good sealing performance. For bagged calcium carbonate, it is necessary to check whether the bags are damaged or have any holes. For those packaged in barrels or other containers, it is necessary to check whether the containers are firm and the seals are tight to prevent the leakage of calcium carbonate during transportation.
Clear labeling: Mark the product name, specification, net weight, production date, manufacturer and other information in a prominent position on the packaging, and affix a danger warning sign (if applicable) at the same time. For example, if the transported is food-grade calcium carbonate, the relevant words "food additive" should be marked. If there are special storage or transportation requirements, they should also be clearly marked.
Vehicle selection and cleaning: Choose appropriate transportation tools based on the volume of transportation, such as trucks, train carriages, etc. Before transportation, the vehicle should be cleaned to ensure there are no residual harmful substances inside and to avoid contaminating calcium carbonate. For the transportation with special cleaning requirements, such as food-grade or medical-grade calcium carbonate, dedicated cleaning vehicles should be used.
Transportation process requirements
Moisture-proof measures: As calcium carbonate has a certain hygroscopicity, moisture-proof measures should be taken during transportation. Plastic film, tarpaulin and other materials can be used to cover the goods to prevent them from getting wet by rain. For cases that are prone to moisture, desiccants can also be placed inside the packaging.
Prevent collision: Although calcium carbonate is relatively hard, during transportation, it is still necessary to prevent violent collision and vibration to avoid packaging breakage and product damage. When loading, stack the goods reasonably to avoid damage to the underlying goods due to excessive height and weight. For fragile calcium carbonate products, such as ultrafine calcium carbonate, even greater protective measures should be taken.
Temperature control: Although calcium carbonate is relatively less sensitive to temperature, its physical properties may be affected to a certain extent in extremely high or low temperature environments. Therefore, during transportation, it is necessary to avoid prolonged exposure to high or low temperatures as much as possible. If transportation is carried out in a hot summer or a cold winter, corresponding heat insulation or heat preservation measures can be taken.
Safe transportation: During the transportation process, traffic rules must be followed to ensure driving safety. Overloading and speeding are strictly prohibited. Drivers must have the corresponding qualifications and experience. At the same time, necessary safety equipment should be provided, such as fire extinguishers, triangular warning signs, etc.
Handling of special circumstances
Emergency response for leakage: In the event of a calcium carbonate leakage, immediate measures should be taken for handling. First, evacuate the people around to avoid inhaling dust. Then, use tools such as brooms and shovels to collect the leaked calcium carbonate and put it in a suitable container. The collected calcium carbonate can be recycled or properly disposed of depending on the situation.
Isolation from other goods: If transported together with other goods, pay attention to their compatibility. Avoid mixing with acids, flammable and explosive substances, etc., to prevent chemical reactions or safety accidents.
