: com2 Basic requirements for packaging and transportation of finished models
2.0.1 Safe and reliable: Choose a reasonable packaging and transportation method to ensure that the model can be delivered to the destination safely and without damage.
2.0.2 Solid and firm: The design and production of the model packaging box must ensure that the model can withstand bumps and impacts during transportation and loading and unloading without being damaged. The model packaging box must be strong enough and easy to disassemble.
2.0.3 Anti-shock measures: When packaging the model, it must be padded with anti-shock materials so that the model and the packaging box are combined into a relatively stable and firm whole with a certain degree of elasticity. Corresponding anti-shock measures should also be taken between the packaging box and the transportation vehicle, which are required to withstand the bumps and impacts generated during loading and unloading and transportation under normal conditions. 2.0.4 Moisture-proof and dust-proof: Moisture-proof and dust-proof measures should be considered in the design and production of the packaging box to avoid rain infiltration and dust pollution. At the same time, the model is strictly prohibited from being exposed to direct sunlight during transportation. Moisture-proof and sun-proof marks should be marked on the packaging box. 2.0.5 Inspection during transportation: According to the mode of transportation, the model transportation should be escorted by a dedicated person or the box should be inspected by a dedicated person at each transfer link. If necessary, a plexiglass peephole should be set on the top of each model packaging box for the accompanying personnel to observe the integrity of the model in the box and remind the handling personnel to be careful to handle it with care.

3 Technical requirements for model design and production for packaging and transportation 3.0.1 The shape of the model chassis should be rectangular. The control of the outer dimensions should be in accordance with the regulations of the loading tool. Generally, land transportation requires that the outer dimensions of each model should be controlled within 1500mm×1200mm×1000mm. When air transportation is selected, the outer dimensions of each model should be controlled within 1200mm×900mm×800mm. When the outer dimensions exceed the permitted range, the model should be made in blocks according to the above dimensions. 3.0.2 The structure of the model chassis: According to the type of model, choose a structure suitable for model packaging. The chassis of the process equipment pipeline model should adopt a support structure with detachable or foldable legs: the chassis of the general layout model or architectural model should adopt a pallet structure without legs.
3.0.3 When the total height of the model plant or frame exceeds 1200mm, it should be made in layers, and the height of the layers should be controlled within the range of .800~~1200mm. 3.0.4 When the model plant or frame is combined with the chassis, it is required to be firmly bonded. If necessary, it should be fixed with bolts at key locations to prevent loosening or falling off during transportation. 3.0.5 The height of the model equipment is required to be controlled within the size range allowed for packaging and transportation. When the total height of the model after the equipment is installed exceeds 1200mm, the equipment model should be made in sections or temporarily not fixed to the chassis (consider separate packaging during transportation). 3.0.6 In addition to bonding and fixing, the installation of tall model equipment should also use bolts to strengthen the positioning of the equipment foundation.
3.0.7 The installation of the model pipeline should take into account the need for shockproofing of the model during loading, unloading and transportation. Model hangers or support parts should be added for preventive reinforcement in places that are prone to vibration and fall off. 3.0.8 The parts or accessories of the model pipeline system should be tightly matched and firmly bonded during assembly, and the loose parts should be bonded with adhesives for a second time before packaging and transportation to increase the connection strength and prevent loosening and falling off.
4 Packaging and transportation of finished models
4.1 Design and production of model packaging boxes
4.1.1 The size of the model packaging box: It should be based on the actual outer dimensions of the model, and each side should be enlarged by 20 to 30 mm as the clearance size in the packaging box, and the enlarged part should be used as the space for the model's anti-cystic cushioning material. The height of the outer dimensions of the model packaging box should be the same size to facilitate transportation and stacking.
4.1.2 Structure of the model packaging box: Choose a combination of square wood frame and wooden board, and use strip iron sheets to reinforce the four corners of the box. Sleepers should be set at the bottom of the box and fixed with bolts to ensure that the packaging box is sufficiently firm.
Opening and closing method of the packaging box: Generally, it is better to open and close from the top. When the model height exceeds 1000mm, the packaging box can be opened and closed by the side box board. The box board for opening and closing should be fixed with wood screws for easy closing and closing operations. 4.1.3 Main materials of the model packaging box: The packaging box panel is made of 1215mm thick wooden board (or machine-made board): The frame material of the box should be square wood of not less than 30mm×50mm, and the sleepers at the bottom of the box should be square wood of not less than 50mm×100mm. 4.1.4 Packaging auxiliary materials: The pressure strips for fixing the model should be made of 30mm×50mm high-quality wooden strips; the anti-vibration cushion materials should be made of 20-30mm thick polystyrene hard foam plastic sheets; the moisture-proof and dust-proof materials can be made of oil felt or plastic film covered on the inner wall of the box and a 0.050.1mm thick plastic film dust cover. 46

Model Packing Preparation
4.2.1 Comprehensive inspection and reinforcement: All the parts of the model that are easy to fall off must be reinforced with secondary bonding, and temporary support parts must be added when necessary to ensure the stability and firmness of the overall installation of the model.
4.2.2 Model numbering and reset marking: Each model and packaging box should be numbered in sequence, and a schematic diagram of the overall assembly should be drawn. The sub-surfaces of the model plant and the segmented surfaces of the equipment should be reinforced and reset marked for unpacking and assembly. 4.2.3 Model chassis feet: The removable feet of the model chassis should be uniformly marked for reset. If the feet are of uniform specifications and interchangeable, they can be packed together. In general, the feet should be packed separately with the block models.
4.2.4 Cleaning work: After the comprehensive inspection and reinforcement work, the finished model should be cleaned once, the dust stains on the model and the scattered objects during the reinforcement process should be removed, and the dust cover should be fixed.
4.3 Finished model packaging
Packing procedures
Packing box quality inspection and internal cleaning;
Cushioning and shockproof materials at the bottom of the box;
Finished model box;
Shockproof materials and fixation of the four sides of the model chassis: Check the packaging quality;
Put in the packing list;
Seal the box;
Spray or write the transportation mark on the outer wall of the packaging box. Use polystyrene rigid foam plastic sheets to pad the bottom and four sides of the model, so that there is a protective layer between the model and the packaging box, which can not only position the model and the packaging box relatively, but also has a certain elasticity to absorb the amplitude generated during transportation. 4.3.3 When the finished model is packed from the top, ropes should be used as lifting tools, and the ropes should be placed in the box with the model: the model chassis support feet should be pulled before the model box and placed at the bottom of the model; other parts and lists that need to be packed with the box should be placed in appropriate positions and relatively fixed. 4.3.4 After all the finished models and parts are packed and properly padded, select appropriate locations to press the model and the bottom of the packaging box with wooden strips to ensure that the model and parts will not move in the box during transportation.
4.3.5 During the packing process of the finished model, parts that are easy to fall off due to vibration can be padded with lightweight foam plastic blocks and temporarily fixed with tape to prevent shaking and inversion during transportation. Do not use shock-proof materials such as foam balls to fill the whole box. 4.3.6 After all the items in the box are packed, fixed, and checked, the model is sealed. The box cover should be fixed with wood screws, and there should be a certain space between the box cover and the top of the model in the box to prevent the model from being damaged after the box cover is pressed.
4.3.7 The outer wall of the model packaging box should be sprayed with eye-catching signs such as "Handle with Care", "Moisture-proof", "Sunscreen", "Do Not Invert", etc. and the packaging box number in accordance with relevant transportation regulations, and the name and address of the shipping and receiving units should be correctly written.
4.4. Model transportation
4.4.1 Transportation mode: Under normal circumstances, railway and road transportation are appropriate. For large-scale device models that need to be transported over long distances, container packaging and transportation are preferred, as they are safer and more reliable than other bulk transportation methods. When choosing automobile transportation, sandbags must be used to weigh down the vehicle in order to improve stability during operation. 4.4.2 Transportation route: Model transportation should be carried out in a way that allows the model to reach the destination directly using one means of transportation, and the probability of mid-way transshipment should be avoided or reduced as much as possible. 48

Articles and explanations
1.0.1-1.0.3 These regulations apply to the packaging and transportation of finished engineering model designs for chemical, petrochemical, pharmaceutical and other industries.
2.0.12.0.5 The requirements for packaging and transportation of finished models, the choice of transportation methods, the design and production of packaging boxes, shockproof, moisture-proof, dust-proof measures, and inspections during transportation are all closely related, so these regulations have clear provisions. 3.0.1-3.0.8 The technical requirements for packaging and transportation of finished models should run through the entire process of model design and production. For this reason, the structural design of the model chassis, the size requirements and combination methods of the model layers and blocks are stipulated. It is required that the dimensions and structure of the model chassis should not only meet the design of the process equipment, but also take into account the possibility and reliability of model packaging and transportation during the model production process. In addition to controlling the total height of the model, reinforcement measures should be taken for the combination of basic models and the positioning of large equipment. When assembling pipelines and parts, the support brackets required by the model should be added and the two bondings required for reinforcement should be performed. 51
