[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - the ventilation pipe work product protection 1], to maintain galvanized steel surface smooth and clean, dry, moisture barrier on the spacious wooden pad holder, stacked neatly. 2, stainless steel, aluminum to be leaning on the gallows in the refrigeration room works, not flat Diego, to avoid scratching the surface drag, cutting should be used no scratches scribing tool. Operation should use a rubber mallet or hammer holster not use a hammer, hammer the point in order to avoid generating rust. 3, the flange should put material classification code law, should be taken to prevent outdoor rain, snow measures to reduce rusting. 4, duct finished code should be placed flat without water, spacious grounds, the system should be numbered when stacked, neat, reasonable, easy to ship. 5, duct transportation and handling should be gently, to prevent damage to the finished product. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - decontamination] clean room clean room temperature and humidity control temperature and humidity are mainly determined according to process requirements, but in the process to meet the requirements of the conditions, should Taking into account the person's sense of comfort. With the improvement of air cleanliness requirements, the process appears to require more stringent temperature and humidity are also trend. After specific process temperature requirements also cited ventilation pipe works, but as a general principle, due to precision more sophisticated, so the range of temperature fluctuations have become increasingly smaller. For example, in the production of large scale integrated circuit lithography exposure process, as the thermal expansion coefficient of glass and the mask and the wafer become increasingly smaller difference. 100 um diameter wafers, the temperature rise of 1 degree, it caused a 0.24um linear expansion project, so there must be a constant temperature ± 0.1 degrees, while the requirements of generally low humidity values, because people sweat later, the product will have pollution project offer, especially sodium afraid semiconductor plant, which workshop temperature should not exceed 25 degrees, high humidity generated more questions. When the relative humidity exceeds 55%, the walls of the cooling water pipes, condensation, when it occurs in a precision device or circuit can cause a variety of accidents. Relative humidity at 50% rust. In addition, the water molecules in the air through the dust silicon surface chemical adhesion adsorbed on the surface is difficult to remove when the humidity is too high. The higher the relative humidity, the more difficult to remove the adherent, when the relative humidity is below 30%, but also due to an electrostatic force so that the particles are easily adsorbed on the surface, while a large number of semiconductor devices prone to breakdown. For optimum humidity range of wafer production 35-45%. Refrigeration room works, engineering, HVAC engineering company Tianjin Jinzhong Ji provided by Tianjin Jinzhong Ji HVAC purification equipment.
