Carton production related accessories storage method

If the carton manufacturing company purchases high-quality carton production auxiliary materials that are backed by the carton manufacturer, improper storage may not only result in deterioration of the auxiliary materials, but also result in wastage of the auxiliary materials. It also causes the physical and chemical performance indicators of the corrugated cardboard and corrugated boxes to decline, resulting in serious appearance quality problems. Even seriously affect the normal production. Therefore, keeping carton production accessories is a work that cannot be ignored and must be done carefully.

I. Storage of powdered materials

1. The place where deposits are kept should be kept clean, ventilated, dry, cool, and protected from the sun and rain. Fire is strictly prohibited. Do not stack with harmful, toxic, corrosive, or odor-containing objects. Product packaging bags should be stacked on the floor more than 100mm above the ground. The stacking should be more than 5OOmm away from the wall, and should be easily transported between days. aisle.

Starch packaging bags must be strong, clean and tidy, sealed at the mouth of the bag, and free from leakage and moisture during transport. Handle with care when loading and unloading. It is forbidden to directly use the hooking bag.

2. Tannins are used as adhesives for vinyl. Storage method

Most of these materials are treated oxidized starches and are generally packaged in plastic woven bags. After the purchase of the factory, as long as the gelatinizer and complexing agent are added, the mixture can be used after stirring. When storing this material in depth, be careful to prevent moisture and prevent breakage of the bag.

Second, the storage of solid and liquid accessories

1. Caustic soda.

Caustic soda is divided into solid caustic soda, caustic soda and liquid caustic soda. Currently, caustic soda is used in the carton industry. The caustic soda and caustic soda must be well protected from moisture and moisture during storage and storage. Otherwise in wet conditions, solid caustic soda and caustic soda will melt. In addition caustic soda has a strong glass erosion.

When you accidentally splash on the eyes and skin immediately rinse thoroughly with water. Caustic soda cannot be stored together with acidic materials to prevent a total reaction in the event of a leak.

2. Borax.

The packaged borax should be protected from rain or moisture, and should not be mixed with moisture and other colored materials to prevent it from becoming agglomerated and deteriorated. It should be stored in a dry and clean warehouse.

3. Hydrogen peroxide (also known as hydrogen peroxide).

Strong oxidants, although they will not burn, but contact with flammable and reducing substances will cause severe reactions and combustion. Therefore, it cannot be combined with reducing chemicals such as sodium thiosulfate and sodium hyposulfite. Hydrogen peroxide has a strong irritant effect on human skin. When hydrogen peroxide is exposed to heat or sun exposure, it will decompose or even explode. In case of alkaline substances, oxygen will be released quickly under any humidity. Storage must be sealed and stored in a cool, dark and ventilated place to prevent decomposition. Handle with care, long storage will reduce the ingredients. Therefore, it should not be stored for too long. Acetylaniline may be added in small amounts, and acetyltetanylaniline may be used as a stabilizer.

4. Bonded potato tongue or "white glue" for color printing of paper and potato veneers.

Most of these adhesives are water-soluble resins and are packed in plastic buckets. Store as long as the seal is stored in a cool dry place.

5. Paper printing ink.

The commonly used inks are classified into three types: water-soluble inks, alkali-soluble inks, and diffusing inks, depending on the type of the binder. They must be stored separately during storage and storage, and should not be confused. After opening, it is estimated that it cannot be used once. It must be stamped and sealed immediately. The used ink must be sealed and sealed after the day is used to prevent evaporation and dust from falling into the ink and causing the surface of the ink to knot. The skin or ink is deteriorating, and the specifications and models must be strictly marked to prevent confusion in the future.

In addition, during the storage of ink, high temperature and sun exposure should be avoided.

The desiccants, defoamers, stabilizers, detackifiers, and other functional auxiliaries used in printing inks are generally chemicals. Therefore, they should be sealed and protected from light and ensure that the labels of various additives are complete and accurate. Mistakes in use make mistakes, leading to serious quality problems.

6. Paper hoop production moisture-proof agent.

There are two commonly used:

a. Solvent-based moistureproof agent must be sealed during storage to prevent volatilization and fire protection. Store in a cool, dry place. Stir well when using.

b. The water-soluble moisture-proof agent should be kept in sealed storage to prevent evaporation, and it should be stored in a cool and dry place to prevent the sun and rain. It should be stored in an environment of 1Occ or more in winter to prevent flocculation. Stir before use, shelf life is generally 6 months.

Third, the storage of sheet materials

1. The printing plate of the flexible printing resin plate must be protected from light to prevent sunlight and ultraviolet light from being irradiated. Otherwise, after being irradiated by the sweet light and the ultraviolet light, it will seriously cause the polymerization of the flexible plate material to cause the plate to be scrapped, and the light will cause The pattern, text, and lines are not deep enough to wash out. In addition, do not place ozone, arcs and organic chemical solvents in order to avoid denaturation of the resin plate.

2. When storing the plates of rubber printing plates, do not put them together with organic solvents such as gasoline, fragrant water, incense water, toluene, and engine oil. Otherwise, the rubber plate will soon deteriorate and become unusable. Avoid strong sunlight exposure during storage and storage, and protect yourself from metal and sharp hardeners.

3. Double-sided pressure-sensitive adhesive tapes must not be in contact with oils, organic solvents and other substances when stored. Otherwise, double-sided pressure-sensitive adhesive tapes will lose their viscous properties and be discarded. They should be placed in a dry warehouse that is one meter away from the heat source.

4. Polypropylene tying ropes should be stacked in a dry, clean, cool warehouse, not close to the fire source, heat source, and keep the package intact. The storage period should not exceed one year from the date of manufacture.

5. Plastic-based pressure-sensitive adhesive tapes (water-free adhesive tapes) shall be stored in a cool and dry warehouse. The floor shall be provided with a backing plate. There shall be a certain distance from the wall to prevent direct sunlight, away from steam pipes, radiators or other heat sources and corrosion. Sexual material.

Fourth, metal accessories and equipment spare parts storage

1. Do not store corrosive and oxidizing materials together with flat and sealed nails for storage of nail boxes, and place them in a dry place to prevent moisture from rusting.

2. Storage of equipment spare parts: A detailed record of the quantities, specifications, models, and purchases should be made of the purchased machinery and equipment. According to the specification, model, manufacturer, purchase time, purchase quantity classified storage, and to do a good job of spare parts rust, dust, classification, positioning, identification, use, distribution, records and other items of custody.

Warehouse custodians should master the performance, characteristics, validity period, storage methods, precautions and requirements of the above-mentioned warehousing materials, and do a good job of moisture-proof, dust-proof, rust-proof, heat-proof, fire-proof, sun-protection, anti-deterioration, and prevention of specifications of the above-mentioned materials. The model is mixed in storage. Accessories must be registered in a timely manner according to category, name specifications, batches, and quantities, and records of receipts and payments must be made. Consistency must be achieved for the account items and the quality of the accessories that are put into production should be good.
