1, eggshell powder. After the eggshell is dried, it is made into eggshell powder as a calcium source feed, which contains some organic matter, generally containing 12.4% crude protein and 24.5%-26.5% calcium. Care should also be taken to prevent eggshell contamination during use. 2, stone powder. That is limestone powder, natural calcium carbonate. Generally containing about 38% pure calcium, it is the cheapest mineral feed for calcium supplementation. Other pure commercial calcium carbonate, chalk and old lime also have the same effect as stone powder. 3, shell powder. Use shell powder as a calcium source feed, should pay attention to the use of shells that have been stacked for many years on the seashore, because after a long time of accumulation, the organic matter attached to it has disappeared, and there are few bacteria; fresh shells should be disinfected because of protein spoilage and attached bacteria. There are many viruses, and it will cause diseases to chickens without disinfection. Generally, the shell powder contains about 96.4% of calcium carbonate, which is equivalent to 38.6% of calcium.
General Purpose Powder-Actuated System is used for building fastening, which have three parts: Actuated tools, Cartridges and fasteners. When Actuated Tool strikes cartridge and cartridge will explode in the inner of tools and produce a lot of high temperature and high pressure gas. The gas will push the piston and the piston will push the fasteners into the basement. Or the gas will push the fasteners directly into the basement. Like this, we can fix a lot of things into concrete and steel basement tightly.
The fundamental is as the following:
The Actuated tools are classified for direct tools and undirect tools, we can also called high velocity and Low velocity tool, the fundamental is as the following:
High velocity tool:
Low velocity tool:
Based on different purpose, Cartridges are classified for different calibers and dimensions. The usual caliber and dimension is as the following:
.27calX11mm(S1)
.22calx15mm(S5)
.22calx16mm(S52)
.27calx18mm(S3)
.25calX16mm(S43)
At the same time, each caliber cartridge is classified for different specification based on the quantity of inner powder, which is marked by different color. when the color is more darker, the power level is stronger. otherwise, the power lever is lighter.
The fasteners are classified for different categories. Each different category is classified for different specification based on different length and diameter. At the same time, it is can also be re-designed based on special use.
The packages are as the following:
1. Tools: one tool/ plastic box/carton or five boxes/carton
2.Cartridge: 100pcs/paper or plastic box, 100boxes/carton.
3. Fasteners: 100pcs/paper box, XX boxes/carton.
For shipment, all cartons will packed by pallet.
