DK 300 automatic sliding door operator (400kg heavy type,)

结构示图

Airtight door should pass high temperature to make glass brick blank above all, undertake roughing to airtight door blank next, the airtight door after roughing should undertake cutting, make the dimension that needs.After fine grinding and polishing, finally clean.After a series of processes, the air tight door blank into a very high transmittance of the air tight door.Changzhou shentong air-tight door manufacturers specializing in the production and processing of various types of air-tight doors.Use of airtight door: used in CT room, can be used to shield x-rays emitted by X-ray machine, reduce the radiation damage to X-ray machine operators.

Airtight door is also known as medical X-ray radiation-proof airtight door plate in the medical field. Airtight door is mainly used for diagnostic X-ray room, CT, ECT, PET, ct-pet and other computer rooms, X-ray photography protection room, observation window on protective door screen, and operational protective screen for nuclear medicine.Pan automatic door hanger lead is a heavy metal with blue silver white.There are four stable isotopes of lead in nature: 204, 206, 207, 208, and more than 20 radioisotopes.Lead is the softest heavy metal and one of the most important. It has good ductility and can be easily alloyed with other metals.Lead oxidizes on the surface of the air, forming a film of lead oxide.Lead carbonate is formed in moist air containing carbon dioxide.These products prevent lead from oxidizing further.Lead is an amphoteric metal that forms lead salts.Lead can interact with HCl or H2SO4 to form an almost insoluble PbCl2 or PbSO4, preventing further corrosion of lead.

Lead is widely used in making lead alloys.Lead alloys are widely used to make battery plates, and lead pipes and plates are used as anticorrosive materials.Lead of air-tight automatic door hanger has good absorption to X-ray and gamma-ray, and is widely used as protective material for X-ray machines and atomic devices.The octane number of gasoline can be improved by adding tetraethyl lead [Pb(C2H5)4].Lead compounds used as pigments include lead white [2pbco3pb (OH)2], lead Dan (Pb3O4), lead yellow (PbCrO4), mituo seng (PbO), etc.Basic lead sulfate, lead phosphate and lead stearate are used as stabilizers for PVC.The main raw material for smelting lead is lead sulfide ore. The grade of ore produced is generally lower than 3%.The common components of lead concentrate are lead 40 ~ 75%, zinc 1 ~ 10%, sulfur 16 ~ 20%, and often contain silver, copper, bismuth, arsenic, antimony and other associated or symbiotic metals.
