The maintenance of steel doors is very important. Proper maintenance can extend the service life of steel doors. Therefore, the maintenance of steel doors is something we must pay attention to every day. The following experts introduce six maintenance knowledge of steel doors:

1. The heating used indoors in winter cannot make the indoor air too dry, and the air should maintain a certain humidity. Try to avoid direct sunlight in the summer to prevent the steel door from being heated.

2. The steel door is at normal room temperature and temperature to prevent the product from being deformed due to excessive temperature and humidity, and the metal is rusted. Keep away from wood when using electric heaters or other equipment during the winter. So as not to affect the wood products.

3. When cleaning steel doors, do not use organic solvents for wiping. Organic solvents will damage the paint layer on the surface.

4, steel wood door paint is afraid of bumping, when opening its steel door, avoid using too much strength to avoid damage.

5, steel wood doors are afraid of water in the process of use, if the door is soaked by water is very troublesome, so take precautions against moisture.

6. When maintaining the steel-wood door with glass, do not infiltrate the detergent or water into the gap of the glass bead to avoid deformation.

At present, the bottleneck and disadvantage of large scale development and manufacturing of isotropic Graphite in China still exist: the design and manufacture of large, special cold and other static presses have not kept up with it. (2) other facilities not perfect, such as the large and super large (1200 mm) Φ graphite impregnated, roasting, graphitization, purification processing, special machine tools machining must be perfect.

Fortunately, there are now cold and other static press factory to start to design and manufacture the large specification (1200mm) cold isostatic pressing machine, if the successful two years can be put into production. At the same time, the development of large scale homogenated graphite is also used in the development of vibration-forming graphite, carbon/carbon composite materials, carbon fiber and other materials used in silicon crystal production.

In the face of such a huge graphite market prospect, and graphite profound understanding to the graphite pieces processing technology progress is the precondition that the future market share, the graphite with milling, car, plane, cutting, drilling, grinding and CNC (CNC), main products including graphite, graphite mold, such as thermal field static pressure graphite, High Purity Graphite, EDM graphite, graphite crucible, graphite flake, Graphite Powder for the SPD, all kinds of graphite profiled, etc., products are now widely used in solar photovoltaic (pv), mold, electronic semiconductor, electrical discharge machining, metallurgy, chemical industry, nuclear industry and quartz, etc. We hope to cooperate with you and develop together with you in the future.
