The function of door and window hardware and the preventive measures for damage

[China Aluminum Network] Door and window hardware accessories is not just gadgets, it is more integrated into the fashion elements, door and window hardware accessories play a huge role in the doors and windows, although the door and window hardware accessories are small, but once it damages will affect The overall beauty and function. Therefore, when it comes to quality, door and window hardware fittings should pay attention to preventing damage, and do maintenance work in advance.

How to prevent damage to hardware:

(1) The type, specification and performance of the selected hardware accessories shall comply with the current national standards and relevant regulations and be matched with the selected plastic doors and windows.

(2) For sliding windows with a width of more than 1m, or with double glass doors and windows, double pulleys or rolling pulleys should be used.

(3) Sliding hinges shall not be made of aluminum alloy materials and shall be made of stainless steel.

(4) When installing hardware with fastening screws, metal liners must be provided. The thickness of the liner should be at least twice that of the fasteners. Do not fasten on plastic profiles or use non-metallic linings.

(5) Hardware fittings shall be installed afterwards. Door and window locks, handles, etc. shall be assembled after the window leaf is inserted into the frame to ensure correct position and flexible switching.

(6) After the hardware is installed, pay attention to maintenance to prevent rust corrosion. In daily use, you must lightly open and close the door to prevent hard opening and closing and damage.

The hardware fittings are the parts that are responsible for the close connection of the frame of the door and the window and the fan. Without it, the doors and windows will only become dead fans, which will lose the significance of the doors and windows. We analyze the effect of hardware accessories on doors and windows from the performance and function of doors and windows:

1. Physical performance indicators of doors and windows include: wind pressure resistance, airtightness, watertightness, thermal insulation, heat insulation, sound insulation, and pressure resistance. The effect of hardware accessories on the front wind resistance performance of doors and windows determines the success or failure of doors and windows; similarly, airtightness, watertightness, heat preservation, heat insulation and sound insulation are all related to the door and window seals involved in hardware accessories. Hardware locks and locks are distributed around the entire door and window. When the doors and windows are locked, the lock points and the lock seats are firmly buckled and cooperate with the hinges (hinges) or the slide stays to provide a strong seal pressing force, so that the seal strips are elastically deformed, thereby providing sufficient doors and windows. The sealing performance of the fan and frame can greatly improve the performance of doors and windows. Similarly, the mechanical performance indicators (opening and closing force, repeated opening and closing) of doors and windows, and other opening and closing requirements are inseparable from the requirements of hardware accessories.

2. Doors and windows are lightweight components, and its use of energy consumption accounts for more than half of the building energy consumption. It is the most important aspect of energy conservation in buildings. The energy saving of doors and windows should be fully taken into account when designing, ie insulation and heat insulation. If there are no multi-point lock hardware fittings, doors and windows do no better, its insulation, heat insulation can be imagined.

3. Similarly, the anti-theft performance of doors and windows is also a concern for owners*. In this regard, the anti-theft performance of hardware accessories is particularly important in the development of smart anti-theft doors and windows.

4, doors and windows have a variety of window shapes and structural forms, and all kinds of window-type functions are dependent on the configuration of hardware accessories. Just imagine, there is no hardware, how to achieve the flat open under the hanging window is open and inverted function? Push-pull folding doors and windows and how to achieve the function of both push-pull and fold? Inverted push-pull, activity shutter, etc., which does not rely on hardware The role of accessories to achieve its unique features? It can be said that hardware accessories are the "heart" of the door and window accessories.

Washed suspensions of Escherichia coli were exposed to different concentrations of chlorine dioxide at various temperatures. Platings of the mixtures to evaluate the numbers of surviving cells were made after 5–300 sec of contact. Survival data were best fitted by a reaction model that is first order with respect to cell concentration and to exposure time. Bactericidal rates were found to increase markedly with both increased disinfectant concentrations and increased temperatures. Activation energies at each concentration of chlorine dioxide are reported.
