In the previous article, we talked about new houses. Basically, the changes are not particularly large. Compared to new houses, second-hand houses may be more concerned by everyone because the original hydropower of second-hand housing is already out of fashion, and there is still a long period of time. There will be a variety of problems, therefore, the second-hand housing of the hydropower reform is also one of the mainstream business of the decoration company, today Xiao Bian will give you talk about if the second-hand housing of the hydropower reform program how to develop! First, the characteristics of second-hand housing water and electricity pipelines 1, according to the number of years to judge Second-hand housing within ten years: Most of the commercial housing built after 2006 will have little difference between the power system and the new housing estate. The circuit modification program will be based on local changes. Generally, there is no need to change the overall system. Second-hand housing in 20 years: Residential communities were built from the end of the 1980s to 2000. Most of the wires use 1.5 or 2.5 square wires, but many home lighting and sockets are only divided into 2-3 loops. This requires the original strong electricity. The system performs optimization adjustments (mainly to increase loops) and tries to retain the original system as far as possible. A long time ago, the second-hand housing: the residential area established before the 1980s, the indoor electric power system basically uses 1.5 square wires, and even uses aluminum core cables. The interior uses pull-wire switches, etc. It is necessary to remove the original cable to thoroughly design a new high-power system. 2, second-hand housing circuit Due to the different construction ages of second-hand housing, the installation of hydropower pipelines may not be the same as it is now, and hydropower reform programs need to be taken into consideration when they are formulated. 3, second-hand housing water features Material and installation design location need to be changed. When building a house by the year 2006, most of the water supply pipes use galvanized pipes or aluminum plastic pipes. Exposed pipe wall will affect the decorative effect. Metal pipes inside and outside wall will rust and pollute the water source. The water supply valve cannot be closed. Water and other problems need to be replaced with materials such as PPR during the renovation; the original water position of the old house is different from the current toilet and equipment requirements, and it is necessary to redesign the direction of the pipeline. Second, key points for the development of second-hand housing hydropower reform programs 1, distribution electrical equipment should be compatible with the charge load Second-hand housing should not use instant-type water heaters or extra-large central air-conditioning, ovens and other appliances. If it is necessary to purchase related electrical appliances, it is necessary to explain the situation during the design of the hydropower, so as to avoid severe current overload and affect normal operation. Second-hand housing weak transformation is often subversive and requires rewiring. 2, pay attention to the quality of the replacement pipe The transformation of second-hand housing waterways, especially galvanized pipes, is considered completely replaced with new-type pipes in the design; if the replacement of the total valves requires temporary stoppage of water for an hour or so, contact the relevant units in advance to obtain consent and stagger the peak cooking time; the drainage pipe is especially Iron pipe to PVC pipe, on the one hand to do a good job of the metal pipe and PVC pipe joints to prevent leakage, and the other belongs to the pressure pipe without drainage, must ensure smooth drainage.

narrow bandpass filters are characterized by high passband transmittance, accurate center wavelength, steep filter edges between pass- and blockband, and broadband blocking range.In manifold applications, the filters are used to select the appropriate part of the spectrum either from a light source or in front of a photodetector.Narrow bandpass filters for biomedical and industrial applications, with FWHM from 10nm to 60nm
Optical Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Optical
IR Narrow Bandpass can use by Fluorescence analyzer, enzyme marker, cable TV upgrade equipment, wireless transmission equipment, mobile phone barcode scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical equipment, infrared ink recognition, red film recognition, face recognition sensor system. Hand held infrared laser rangefinder, laser rangefinder, optical instruments, medical and health equipment and testing instruments.
