The gusset plate is an important part of the ceiling. At present, the ceiling gusset plate on the market is mainly made of metal material, and the metal material is more widely used in the aluminum gusset plate, and as a consumer, how to make good and bad aluminum gusset products on the market Pick it up? Jiuzheng Xiaobian is here to make the following tricks for you, hoping to help the majority of owners to buy.
1. Aluminum, the aluminum used in good brands is the aluminum of the regular aluminum factory. The flexibility and strength are much stronger than those of the garbage aluminum. You can do an experiment and go to the store to find two large price gaps. The model of the brand, bending him by hand, this time the aluminum (garbage board) will be easily bent, and will not restore the original shape, and the good aluminum bending will take more effort And after bending, it will rebound to some extent, which is the difference in toughness and strength between aluminum.
2. Process, aluminum gusset plate is divided into three types: spray coating, roller coating and film coating. At present, the most popular one is the laminated board, which is rich in color and colorful, and has the characteristics of light weight, water resistance, no dust absorption, corrosion resistance, easy scrubbing, easy installation, strong stereoscopic effect, soft color and beautiful appearance. User's welcome.
3, keel, aluminum gusset ceiling keel has two installation methods of light steel keel and wood keel, wood keel will be deformed after damp, it is best to use light steel keel to install.
4, service, choose products more important is after-sales service, a strong brand, its pre-sale, sale, after-sales service is also very perfect.
5, thickness, standard aluminum gusset plate thickness is 0.6mm, which is also the standard thickness specified by the state.

Snowmelt agent is mainly divided into two categories, one kind is potassium acetate as the main composition of organic snowmelt agent, although this kind of snow melt agent snowmelt effect is good, no corrosion damage, but its price is too high, generally only applies to the airport and other places. The other group is chlorinated salt, including Sodium Chloride, Calcium Chloride, Magnesium Chloride, potassium chloride, etc., which is known as' ice salt '. Its advantages are cheap, and the price is only about a tenth of that of organic snowmelt, but its corrosion of large public infrastructure is serious.
There are two chlorine salt snow removal effect of snowmelt agent, in addition to dissolved salts in the absorption of heat, is another role of brine freezing point is lower, so again to dissolve the salt in the water after it will be difficult to ice formation, thus is advantageous to the row of snow.
When the snow melts in water, the concentration of ions in the water rises, causing the vapor pressure of the water vapor to drop, but the solid vapor pressure of the ice remains unchanged. The ice melts in order to achieve the state of water mixing and solid vapor pressure. This principle also explains why salt water is not easy to freeze.
