The protective door is a door that can resist various shock waves or heavy objects. The ones that can block rays or protect personal safety can also be called protective doors. The protective door is made of steel and has durability. The following mainly introduces the three characteristics of lead protection door and concrete protection door safety protection door.
Lead protection door
1. The lead protection door adopts the national standard steel skeleton, made of stainless steel as the panel, sandwiched with high-quality radiation protection lead plate, combined with advanced cold high-pressure bonding technology, with special stainless steel protective door special door hinge, high quality Hardware, imported protective door special engineering locks.
2, the current common lead protection door lead thickness is 0.5-20mm, the common specification is 1000*2000mm, the best machine in China can make the widest 1300mm, the longest 8000mm, mostly made of 1# electrolytic lead, there are also on the market Made from recycled lead, the quality is slightly worse and the price is a little different.
3. The lead plate used for the lead protection door is a plate rolled with metal lead. It has strong anti-corrosion, acid and alkali resistance, acid-proof environment construction, medical radiation protection, X-ray, CT room radiation protection, aggravation and sound insulation. And many other aspects, but also a relatively inexpensive radiation protection material. It is mainly used for import and export that needs to block the passage of radiation, and is often used in hospitals, computer rooms and mining areas. According to the opening method, it is divided into electric radiation protection lead door and manual radiation exposure lead door; according to the opening direction, it is divided into 90 degree flat opening and 180 degree linear push-pull protection lead door.
Concrete protective door
1, mainly used in industrial linear accelerator, gamma ray protection shielding (cobalt-Co60, 铱-192, linear accelerator 2MeV, 4MeV, 6MeV, 9MeV, 12MeV, 15MeV). The gate is in the form of a steel structure with a concrete layer as a shielding filler.
2. Compared with the steel lead structure, the protective door has more stable performance, lower cost and better shielding effect. Different sizes of door sizes can be designed according to the dose level and workpiece size of different ray devices, and various load-bearing and transmission modes can be designed according to different door weights. The flat-lane rails do not need to be disconnected. Convenient for operation, people and cars, forklifts can directly enter and exit, to meet the industrial x-ray inspection health protection standards "GBZ117-2002".
Security door
1. The safety protection door frame is made of 30*30*1mm Shougang square tube. The panel is composed of diamond-shaped steel mesh and 1mm thick steel plate hydraulic punching combination. It is humanized design, scientific and reasonable, ensuring construction safety and welding technology. Easy to install and use. The panel paint adopts the spray-painting process, which is beautiful and durable. It is the first choice for the standard chemical industry and one of the safest products designated by the safety supervision station.
2, safety protection door roots, construction site, outer frame step distance 1.8m, spacing 1.5m, human goods construction elevator car 1.5m, national unified standardization specifications for each layer 2 groups each group 2 doors, height 1.8m, width 1.5 m, leaving 5cm of active clearance up and down and left and right.
