Important relationship between lead plate and design thickness of protective layer

Factors related to the design thickness of the lead plate and protective layer:
1, the nature of the protective layer of the data, the general density of the data has a better protective effect. Such as lead, steel, concrete, lead glass, etc.
2. The influence of environmental factors, whether there is any personnel working or walking outside the flaw detection room to decide whether to add or reduce the degree locally.
3. Type of X-ray machine (unidirectional machine or circumferential machine),
4, the length of the operator's weekly operation time,
5. The distance between the protective layer and the X-ray machine target (ball tube),
6. The tube voltage and tube current of the X-ray machine are too small
The low-efficiency operation of the lead plate profession will become the norm, and some lead plate enterprises will continue to lose cash, and even lead plate may break the lead plate capital chain. Looking ahead to the lead board store, the lead board store will still be the lead board store with over-capacity.
The national policy is gradually being implemented, from reducing production capacity to energy conservation and environmental protection, from quality improvement to high-tech research and development, etc. are all going step by step. The medium and heavy plate market in the next year will be a relatively quiet year, although it will not change much from a large scale, but there will still be changes in a small scale.
Whether it is the price change or the requirement of improving the quality of steel itself or solving the overcapacity, even the supervision mechanism for all aspects of steel mills will gradually deepen. It is estimated that the overall price trend of domestic medium and heavy plate shopping malls will be stable and strong. Lead plate demand is relatively stable, which can also be seen from the inventory changes throughout the year.
Downstream anti-radiation lead plate terminal procurement is still cautious, it is estimated that the short-term anti-radiation lead plate dry flow price will be low consolidation.
Anti-radiation lead board store: This week, the price of anti-radiation lead board in North China is stable and loose. The inventory of anti-radiation lead board enterprises is not high, and the shipment of anti-radiation lead board has been improved and partially adjusted. At present, the supply side of shopping malls in a single area is relatively tight, and independent coking plants are still processing at full capacity. However, due to the general malaise of steel, iron ore and other related types, it is estimated that the price of the main stream of short-term coke shopping malls has fallen steadily.
