What advantages does the drought-resistant special water tank play?
The main function of the drought-resistant water tank is to store and transport water. In production, its production process is suitable for any polyethylene technology and belongs to the forefront of industry technology! It uses high-molecular composite materials, which are wear-resistant, flame-retardant, highly soft, and can be folded at will. Due to its good insulation and corrosion resistance, the drought-resistant water tank can also be used to transport some special substances and is widely used. Its capacity can reach 25,000 liters, and the quality control is more stringent. It is suitable for various terrains, especially hilly and mountainous areas with severe water shortages. When the water supply container is filled with water, it becomes a round container. In addition, the design of the conical water tank can be improved according to the needs of users, which can be open or with a lid. The material of the water tank is a thermoplastic polyurethane, or PVC coated cloth, which has the characteristics of high strength, light weight, non-toxic, odorless, no water pollution, good environmental protection performance, aging resistance, and water resistance. In addition to its beautiful appearance, the water tank is convenient and practical. It is easy to carry, simple to pack, and can be folded when there is no water, giving full play to the incomparable advantages of iron and plastic containers. Not only these aspects, the drought-resistant water tank can also be used in other aspects, such as rainwater collection, fire fighting, life-saving, public emergency, etc., and can also be used to store and transport drinking water or other liquid bulk products. The loading and unloading is simple and easy to transport, which can save time, labor and cost. In terms of storage, the drought-resistant water tank is stable and will not be unusable due to seasonal changes. When not in use, it can be folded and stored after cleaning to reduce the occupied space and facilitate the next use.

What types of liquid transportation are flexitanks suitable for?
A flexitank is a foldable and environmentally friendly soft container suitable for the transportation of liquid goods. It can be loaded into a 20 foot ISO standard container and can be used for multimodal transportation by road, rail, waterway, etc. It is divided into disposable flexitanks and reusable flexitanks. The material used is polypropylene (PP) for the outer layer and polyethylene (PE) for the inner layer. It is usually equipped with a loading and unloading valve and a gas release valve. The edges are welded with double passes, and the corners of the liquid bag are reinforced with technology. Firstly, the food category that everyone is familiar with is concerned about pollution, so it is suitable to transport it in flexitanks. Of course, it is only suitable for some non corrosive liquids, such as wine, edible oil, various concentrated fruit juices, food additives, sorbitol, palm oil, soy sauce, yellow wine, mineral water, malt extract, various syrups, etc. This can be transported over long distances using flexitanks, which is an effective way for our products to safely reach the other shore. Another concern is the transportation of some industrial products, which can actually use oils and fats, such as lubricants, lubricant additives, transformer oil, white oil, tung oil, glycerin, coconut oil, hydraulic oil, industrial gear oil, castor oil, high-fat fatty acids, oleic acid, etc., which can meet the higher efficiency transportation mode of various products. Another option is that flexitanks can also transport some non hazardous liquid chemicals, which can be used for common container liquid bag transportation modes such as plasticizers, resin compositions, cleaning agents, disinfectants, surfactants, polyols, feed additives, silicates, saline solutions, etc.  The above content is for reference only.
