Description

Technical Field

[0001] The invention relates to the technical field of polyimide slurry production, and specifically, it shows a method for batch packaging and transportation of polyimide slurry. Background Art

[0002] The characteristics of polyimide in performance and synthetic chemistry make it difficult to find such a wide range of applications as polyimide among many polymers, and it shows extremely outstanding performance in every aspect. Polyimide slurry has outstanding high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation properties, and can be used for a long time in air at 250-280℃. It is particularly suitable for use as a flexible printed circuit board substrate and various high temperature resistant motor and electrical insulation materials.

[0003] At present, most manufacturers usually use steel pallets to package barrels when transporting polyimide slurry. However, this type of packaging may cause the following problems during transportation: 1. During packaging and transportation, the barrel is prone to collide with the steel structure, causing damage to the barrel body, affecting subsequent use, and there is a risk of leakage; 2. During transportation, the barrel body collides with the steel structure, which may cause the bottle cap to become loose, causing particles to enter the product, affecting product quality. Summary of the invention

[0004] The purpose of the present invention is to provide a method for batch packaging and transportation of polyimide slurry with good transportation effect.

[0005] The technical solution is as follows:

[0006] A method for batch packaging and transportation of polyimide slurry comprises the following steps:

[0007] First, fill the polyimide slurry into packaging bags in batches, and then place each packaging bag in a NOWPak barrel;

[0008] Place nine NOWPak barrels in a nine-square grid on a horizontal pallet, place a horizontal corrugated cardboard on top of the nine NOWPak barrels, and place another nine NOWPak barrels in a nine-square grid on the corrugated cardboard;

[0009] A four-corner bag is placed on the top of the nine NOWPak barrels on the upper layer, and the upper and lower NOWPak barrels and pallets are wrapped together with a stretch film;

[0010] Tie a circle of plastic-steel tie around the outer periphery of the nine NOWPak barrels above the pallet and the outer periphery of the nine NOWPak barrels above the corrugated cardboard.

[0011] The NOWPak barrels on the upper and lower layers are aligned one by one.

[0012] Among them, the wrapping film is wrapped upward from one side of the bottom of the pallet by a wrapping machine until the wrapping film wraps the four corner bags, and then the wrapping film is wrapped downward from the top until it wraps the other side of the bottom of the pallet; the wrapping film is wrapped upward from one side adjacent to the bottom of the pallet by a wrapping machine until the wrapping film wraps the four corner bags, and then the wrapping film is wrapped downward from the top until it wraps the other adjacent side of the pallet, and the two wrappings are cross-wrapped.

[0013] Among them, cardboard corner protectors are placed around the tops of the nine NOWPak barrels on the upper layer. The cardboard corner protectors, the upper and lower layers of NOWPak barrels and the pallet are fixed together with plastic-steel tie straps through a cross-binding method.

[0014] Among them, the plastic-steel cable ties are fixed by packing buckles.

[0015] Wherein, the pallet is a plastic pallet.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The barrel body is fastened with plastic-steel tie, and the outer diameter of a single barrel is much smaller than the size of the pallet. Excessive impact with foreign objects will not cause damage to the barrel body or loosening of the bottle cap, which enhances the stability of product quality.

[0018] 2. Use plastic pallets, and there is no need to transport the pallets back, saving transportation costs.

[0019] 3. The barrels are closely arranged, which greatly increases the cargo carrying capacity compared to traditional steel pallets. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The embodiment of the present invention provides a method for batch packaging and transportation of polyimide slurry, which is used to solve the technical problems raised in the background technology.

[0025] The specific steps include:

[0026] Step 1: The packaging staff first fills the polyimide slurry into packaging bags in batches. After the packaging bags are sealed, each packaging bag is placed in a NOWPak barrel.

[0027] The packaging staff labels and bags the NOWPak barrels one by one, and tightens the seals with cable ties.

[0028] Step 2: The packaging staff moves the NOWPak barrels to a horizontally placed pallet, a total of nine NOWPak barrels, which are arranged in a nine-square grid.

[0029] Step 3: The packing staff places a horizontal corrugated cardboard on the top of the nine NOWPak barrels so that the tops of the nine NOWPak barrels are completely covered. The packing staff then moves nine NOWPak barrels and also places the nine NOWPak barrels in a nine-square grid on the corrugated cardboard. It is worth noting that the positions of the NOWPak barrels on the upper and lower layers must be aligned one by one.

[0030] Step 4: The packaging staff puts a four-corner bag on the top of the nine NOWPak barrels on the upper layer to completely cover the top of the nine NOWPak barrels on the upper layer, and then wraps the upper and lower NOWPak barrels and the pallet together with the wrapping film. The specific operation is:

[0031] Wrap twice in a cross-shaped manner. First, use a wrapping machine to wrap the wrapping film upward from one side of the bottom of the pallet until the wrapping film wraps the four corner bags, and then wrap the wrapping film downward from the top until it wraps the other side of the bottom of the pallet; then use a wrapping machine to wrap the wrapping film upward from one side adjacent to the bottom of the pallet until the wrapping film wraps the four corner bags, and then wrap the wrapping film downward from the top until it wraps the other adjacent side of the pallet.

[0032] Step 5: The packaging staff uses plastic-steel cable ties to tie up the upper and lower NOWPak barrels as a whole, and uses packing buckles for final fixation, that is, a circle of plastic-steel cable ties is tied around the outer periphery of the nine NOWPak barrels above the pallet and the outer periphery of the nine NOWPak barrels above the corrugated cardboard.

[0033] Step 6: The packing staff places an "L"-shaped cardboard corner protector on each of the four sides of the top of the nine NOWPak barrels on the upper layer, and uses plastic-steel tie bands to fix the cardboard corner protectors, the upper and lower layers of NOWPak barrels and the pallet together through the cross-binding method.

[0034] like Figure 1 and Figure 2 The figure shows the overall schematic diagram of the final packaging according to the above packaging method.

[0035] It comprises a plastic pallet 1, on which nine NOWPak barrels are placed in a nine-square grid, on which a corrugated cardboard 2 is placed, on which nine NOWPak barrels are placed in a nine-square grid, and their placement positions are aligned one by one with the placement positions of the nine NOWPak barrels in the lower layer.

[0036] A four-corner bag is placed on the top of the nine NOWPak barrels on the corrugated cardboard 2 to cover the upper NOWPak barrel, and a stretch film is used to tie a knot on the plastic pallet 1, that is, a wrapping machine is used to wrap the stretch film starting from the plastic pallet 1, from the bottom upward until the bag is wrapped, and then from the top downward until it is wrapped to the plastic pallet 1, and this is repeated twice.

[0037] The nine NOWPak barrels on the plastic pallet 1 are fastened in a surrounding manner using a plastic-steel cable tie 4 and fixed with a packing buckle. The nine NOWPak barrels on the corrugated cardboard 2 are also fastened in a surrounding manner using a plastic-steel cable tie 4 and fixed with a packing buckle.

[0038] Four cardboard corner protectors 3 are placed on the upper nine NOWPak barrels to form a frame shape, and two plastic-steel cable ties 4 are used to tighten the two opposite ends of the two cardboard corner protectors 3 and the plastic pallet 1 from top to bottom, and fixed with packing buckles; two plastic-steel cable ties 4 are used to tighten the other two opposite ends of the cardboard corner protectors 3 and the plastic pallet 1 from top to bottom, and fixed with packing buckles.

[0039] The nine barrels are fastened with plastic-steel cable ties to prevent damage to the barrels or loosening of the bottle caps due to excessive collision with foreign objects, thereby enhancing the stability of product quality; the barrels are closely arranged, which greatly increases the cargo carrying capacity compared to traditional steel pallets, and can pack 19 barrels at a time, with a large transportation volume; the use of plastic pallets eliminates the need to transport the pallets back, saving transportation costs; the layout of each barrel and the upper and lower barrel layers is stable and safe, and the polyimide slurry will not be contaminated, thus ensuring product quality.

[0040] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
