Description

Antibacterial steel gypsum panel structure{ANTIMICROBIAL STEEL GYPSUM PANEL STRUCTURE}

The present invention relates to a panel structure, and more particularly, to an antibacterial steel gypsum panel (SGP) structure.

In general, clean rooms are used to improve product quality and reduce defect rates in manufacturing processes that require high clean environments, such as semiconductor manufacturing processes, pharmaceutical manufacturing processes, and various food manufacturing processes. In addition, clean rooms are also used in hospital intensive care units and operating rooms. This clean room has a structure that is completely blocked from the external environment in order to block the inflow of dust or bacteria. In addition, efforts to provide an environment in which dust and bacteria hardly occur inside the clean room are required.
On the other hand, in a clean room, there are many cases where partitions are constructed to divide the work space. In order to divide the space with partition construction, a lot of panel construction is being carried out. Korean Patent Registration No. 10-1150024 discloses a clean room panel including an operating room equipped with an antibacterial function.
However, the conventional clean room panel structure mainly provides an antibacterial function only to the panel itself, that is, a steel plate. Since the conventional panel structure has an antibacterial function only in the panel, there is a risk that fine dust adheres to the connection part connecting the panels or other parts of the finishing material, and bacteria propagate. Therefore, there is a risk that the conventional panel structure is used in a semiconductor manufacturing plant that requires a fine manufacturing process or an operating room directly connected to the life of a patient.

Referring to FIGS. 1 and 2, the antibacterial steel gypsum panel structure 10 includes a plurality of panels 100, connecting units 200 to each panel 100, and a mop disposed under the panels 100. It may include a receiver 300, a ceiling receiver 400 disposed on the panels 100, and a finishing receiver 500 for closing both ends.
Each of the panels 100 may include two steel plates 110 spaced apart from each other and facing each other, two gypsum boards 120 spaced apart and facing each other, a stud 130, and a filler 140. The two steel plates 110 may face each other with a first length LT1 and may be spaced apart. In this case, a direction in which the two steel plates 110 are separated may be a thickness direction of the panel 100. Each steel plate 110 may be composed of a plurality of layers.
3 is a view for explaining a steel plate of the antibacterial steel gypsum panel structure according to an embodiment of the present invention. Referring to FIG. 3, according to an embodiment, the steel plate 110 includes a base metal plate 101, a first zinc layer 102 and a first pretreatment layer 103 sequentially disposed on an upper surface of the base metal plate 101. ), the lower coat layer 104 and the upper coat layer 105, a second zinc layer 106, a second pretreatment layer 107, and a functional paint layer 108 that are sequentially disposed on the lower surface of the base metal plate 101 It may include. The surface of the steel plate 110 exposed to the outside may be a top coat layer 105. That is, the top coat layer 105 is exposed to the outside, and the functional paint layer 108 may face the gypsum board 120.
The base metal plate 101 may include a cold rolled steel sheet. For example, the base metal plate 101 is a hot-dip galvanized steel plate (galvanized, GI), an alloyed galvanized steel plate (galvanneled, GA), an aluminum-galvanized steel plate (galvalume, SGL), and an electro galvanized steel plate (electro galvanized, EGI). , Aluminum (AL), cold-rolled stainless steel (stainless steel, SUS), Black plate (BP), TFS, TP, may include at least one of ALCOT (hot dip aluminized steel).

In addition, the steel plate 110 includes a special uninterruptible paint, and the surface electrical resistance of the panel structure 10 can be maintained at 10 ⁶ to 10 ⁹ Ω by the special uninterruptible paint, so that it can have semi-permanent antistatic performance. When static electricity is generated, electronic components may rupture or deteriorate due to dust contamination and ESD discharge.
When charged dust floating in the air approaches the charged object, attractive force acts by the coulomb force generated by electrostatic induction, and the dust may adhere to the surface of the charged steel plate 110. To prevent this, the surface of the steel plate 110 may be coated with an uninterruptible paint to prevent dust from sticking to it. In addition, when the surface of the charged steel sheet 110 is discharged to an electronic component or object to be coated, the discharge current passes through a region where the resistance of the electronic component or object is low. The thermal energy generated at this time may cause thermal damage in proportion to the discharge current. Accordingly, ESD discharge can be prevented by coating the surface of the steel plate 110 with an electroless paint.
