In 1987, the Chinese feed classification code was established under the auspices of Academician Zhang Ziyi. The total is divided into eight categories and 17 sub-categories. The various feeds are labeled with the corresponding China Feed Code (Feeds Number of China, CFN) and the coding mode is 0-00-0000. The first digit is the IFN classification number, the second and third digits are the CFN subclass number, and the fourth digit is the specific feed number. Such as 4-07-0279 level corn. 4-07-0280 secondary corn. In terms of feed characterization, both product characteristics and nutritional characteristics are taken into account.
Stainless steel square washer, which fits into slots and channels and have flat sides to keep them from rotating. They are wider and thicker than most round washers, making them good for distributing heavy loads. products are made of 304 316 stainless steel washers have good chemical resistance and may be mildly magnetic. these square washers are for use with blind rivets for extra support when fastening into soft material. They fit into slots and channels and have flat sides to keep them from rotating. They are wider and thicker than most round washers, making them good for distributing heavy loads.
Square taper washers are special types of washers that have a square shape with tapered edges. They are commonly used in construction and engineering applications to provide a secure and tight fit between two components.

The tapered edges of square taper washers allow them to be easily inserted into square holes or slots. Once inserted, the washer prevents the component from rotating or moving, providing stability and preventing loosening.
These washers are typically made from steel or other durable materials and are available in various sizes to accommodate different applications. They are commonly used in conjunction with bolts or screws to ensure a secure connection between two parts.
Square taper washers are commonly used in automotive, machinery, and structural applications where a strong and stable connection is required. They are designed to distribute the load evenly across the surface, reducing the risk of damage or failure due to excessive stress or movement.
