Problems solved by technology

The molding and material of the bowl floppy disk, the most suitable molding process for the production of the bowl floppy disk, adopts blister molding, and the vacuum blister molding process is prone to perforation, which affects the molding effect, and the bottom of the bowl is thin, which does not meet the agricultural requirements, and the production efficiency Also compared, improved production materials
Plastic floppy disks currently on the market are mostly made of poor weather resistance polyethylene, polypropylene, and polyvinyl chloride with poor heat resistance. As for plastic floppy disks, they should be made of suitable and economical materials. In terms of plastic wrap, polyethylene and polypropylene bowl floppy disks are slightly inferior in toughness and strength compared to PVC bowl floppy disks, and are easy to break
However, PVC floppy disks are not suitable for the cultivation of oil-containing crops, and cannot be heated at high temperatures. Due to the poor heat resistance of PVC materials, they decompose and release hydrogen chloride gas when exposed to high temperatures. Plasticizers DEHP and DOP are usually added. (dioctyl phthalate), and a small amount of heat stabilizer to reduce the processing temperature. PVC itself is a hard material. After adding plasticizer, it will become soft and easy to bend, so it has its application. Agents DEHP and DOP have hepatotoxicity and can cause can
