Broken bridge aluminum doors and windows refers to the use of heat insulation broken aluminum profiles and hollow glass, with energy, noise, noise, dust, waterproof and other functions. The thermal conductivity K of the broken bridge aluminum doors and windows is 3W/m2&8226; below K, it is reduced by half than the heat loss of ordinary doors and windows, the heating cost is reduced by about 30%, the sound insulation is more than 29 decibels, and the watertightness and airtightness are good. Class A1 window standard.

Broken bridge aluminum doors and windows have many advantages, mainly include: reduce the heat conduction: the use of thermal break bridge aluminum alloy, the thermal conductivity of 1.8 ~ 3.5W/m2? K is much lower than the ordinary aluminum alloy section 140 ~ 170W/m2?k The use of hollow glass structure, the thermal conductivity of 3.17 ~ 3.59W/m2? K is much lower than the ordinary aluminum alloy 6.69 ~ 6.84W/m2? K, effectively reducing the heat transmitted through the doors and windows. Anti-condensation: The temperature of the inner surface of the profile with the insulating strip is close to the room temperature, which reduces the possibility that the indoor moisture will condense on the surface of the profile due to over-saturation. Energy savings: In winter, window frames with thermal insulation can reduce 1/3 of the heat lost through the window frame; in the summer, if there is air conditioning, the window frame with thermal insulation can be more Reduce the loss of energy. Protecting the environment: Through the application of thermal insulation systems, energy consumption can be reduced, while environmental radiation due to air conditioning and heating is reduced. Health: The exchange of heat between the human body and the environment depends on the temperature of the indoor air, the speed of air flow, and the temperature of the outdoor air. By adjusting the temperature of doors and windows to make it not lower than 12-13 °C, it has reached the most comfortable environment. Reduce noise: The use of hollow glass structures with different thicknesses and thermal break aluminum profile cavity structure can effectively reduce the resonance effect of sound waves, prevent sound transmission, and reduce noise by more than 30 dB. Colorful and colorful: After anodic oxidation and powder coating surface treatment, it can produce more than 200 different colors of aluminum in RAL color system. After rolling and pressing, the insulated aluminum alloy doors and windows produce indoor and outdoor two-color windows with different colors.
Broken aluminum doors and windows have now become a new force for domestic doors and windows. The principle of broken bridge aluminum-plastic composite windows is to use plastic profiles (more than 1250 times higher than aluminum profiles) to separate and tightly connect two layers of indoor and outdoor aluminum alloys. As a whole, it constitutes a new type of heat-insulating aluminum profile. Using this type of profile for doors and windows, its heat insulation is in the same grade as the plastic (steel) window--national standard, which completely solves the problem of rapid conduction and heat dissipation of the aluminum alloy. Do not meet the fatal problem of energy-saving requirements, while taking a number of new forms of structural cooperation, completely solved the "aluminum alloy sliding window sealing is not strict," the old hard problem.

Erlenmeyer flasks are widely use in cell suspension culture, medium confifiguration, mixing and storage.It is suitable for culturing cell lines with high oxygen requirements. It can also be used to culture bacteria, fungi and animal and plant cells in suspension. Compared with culture flasks, dishes and spinner flasks, it requires less work and is an economical solution. Cell Culture tool ideal for media preparation, mixing and storage.Reduces the chance of experimental personnel being infected during bacterial culture work.
