Successfully cracked three major problems for the realization of calcium carbide soft bag transport

The situation in which calcium carbide was transported by steel drums has been broken by vinylon water-soluble yarn composite soft bags. Ningxia Railway Lili Industrial Co., Ltd. has successfully completed the trial production and trial development of the Vylon water soluble yarn composite soft bag for calcium carbide transportation and packaging, and has been praised by the company.

Vinylon water-soluble yarn composite soft bag has high strength and low breakage rate. The needle hole of the packaging bag has a telescopic function. When the pressure in the bag increases, the pin hole of the sewing thread can be exhausted to prevent the occurrence of obstruction to ensure the safety of transportation. The inner layer has a moisture-absorbing effect and retards the decomposition reaction of calcium carbide. Under normal circumstances, maintaining pressure in the inner bag to resist the entry of outside air, thereby greatly reducing the rate of calcium carbide powder. The vinylon yarn used in the product is a material that is not treated with acetal and is easily dissolved in 80sE water, which is beneficial to the recycling of the bag. At the same time the product also has a buffer, heat resistance, anti-aging properties. As the material is soft, the empty bag can be folded and compacted and packaged for transport.

According to reports, the vinylon water-soluble yarn composite soft packaging bag is a three-layer structure, the middle layer and the outer layer are composite braided materials, and the inner layer is a bonded mesh vinylon-soluble yarn. Using a special bag machine processing production.

Ningxia Railway Lili Industrial Co., Ltd. is also used to ship potassium hydroxide and sodium sulfide. It is said that it is also preparing to ship other powdered mineral products, as well as grain, salt, feed, etc.

The trial shows that this kind of bag is used for calcium carbide transport packaging, and the comprehensive cost per ton of calcium carbide transport packaging can save about 170 yuan. Among them, the cost of packaging was reduced by 55%, the transportation cost was reduced by 11%, and the rate of powdered calcium carbide was reduced from 16% of steel drums to about 5%.

The company also revealed that the adhesive used in the production of vinylon water-soluble yarn composite flexible packaging bags was made by the company using proprietary technology. This adhesive has a strong ability to bind paper and yarn and solves the problems of quick-drying and flame-retardant.

After testing, the physical and chemical indexes of the vinylon soft-wool yarn composite flexible packaging bag all meet the export packaging standards, and the technical performance is at the leading level at home and abroad.

It is reported that this product has now been applied in China's railway calcium carbide transportation, and gradually gain more user approval.
